This case report describes a successful orthodontic therapy of an adult female treated by mandibular central incisor extraction and vestibular fixed appliances. The patient presented a skeletal Class I with normodivergent facial pattern, Class II subdivision dental relationship, extremely deep Curve of Spee and severe overbite. Moreover, during the treatment, the upper left first molar does not respond to orthodontic forces due to tooth ankylosis, augmenting the difficulty of this case. Despite...

CONCLUSIONS: There were considerable differences both between and within racial groups in crown height, crown width, and numbers of clusters, which should be taken into account during bonding. Although single-bracket placement guides specific for ethnicity may be feasible for the mandibular arch, the significant diversity in number of clusters in the maxillary arch indicates that more accurate bracket placement guides that take into account such heterogeneity are required.

CONCLUSIONS: This investigation is the first attempt to assess individual compliance with EMA for reporting awake bruxism. Results suggest that a smartphone-based strategy can have interesting potential. The compliance rate reported in this study will serve as a comparison standpoint for future investigations.

This case report discussed a combined surgical-orthodontic rescue of two impacted teeth in a large dentigerous cyst by the means of fixed orthodontic appliances. After careful evaluation of the 3D radiographic exams, extraction of the deciduous elements was carried out, followed by marsupialization and orthodontic traction of the impacted teeth. Surgical procedures, pre- and posttreatment records and orthodontic biomechanical evaluations are discussed.

by Daniele Manfredini on Aprile 24, 2019 at 10:00 am

CONCLUSION: The null hypothesis of an absence of correlation between tooth wear and sMMA could not be rejected, implying that tooth wear cannot be used as an indicator of ongoing SB or sMMA. Future studies taking into account the multifaceted nature of tooth wear and the complex natural course of sleep phenomena are encouraged to investigate the issue further, at the individual level.

This case shows that using a rapid palatal expander (RPE) and then a pendulum appliance anchored to palatal miniscrews is an option for improving treatment management in a noncompliant patient requiring maxillary expansion and molar distalization in the late mixed dentition. First, an RPE was used to expand the maxillary arch. Then, a modified pendulum appliance was used to distalize the maxillary first permanent molars. Optimal positioning of two palatal miniscrews enabled both appliances to be...

CONCLUSIONS: Considering all tooth and movement types of the 45 participants, the mean total imprecision was 2.1 ± 0.9 degrees, with respect to a mean prescription of 5.7 ± 2.2 degrees. There was no difference in accuracy between replacing the aligners accompanied by low-frequency vibration every 7 days and replacing them every 14 days without vibration. Moreover, low-frequency vibration seemed to improve the accuracy of a conventional protocol in terms of upper incisor rotation.

by Luca Lombardo on Settembre 2, 2018 at 10:00 am

CONCLUSION: Combining aligners with appropriate auxiliaries is an efficacious means of resolving orthodontic issues such as class II, dental crossbite, and crowding in a time-frame comparable to that of conventional fixed orthodontics. Furthermore, this system is associated with optimal oral hygiene and excellent esthetics.

by Anna Colonna on Agosto 15, 2018 at 10:00 am

Objective: To investigate the association between volumetric measurements of craniofacial morphology and temporomandibular disorders (TMDs). Methods: Computerized tomography (CT) scans of 20 individuals aged 18 to 40 with (TMD group) or without TMJ pain (control group) were gathered based on a case-control design. Three-dimensional reconstructions were performed to evaluate the gonial angle, condylar volume, and the distance between the posterior edge of the condyle and the sigmoid notch....

This case report describes the use of a miniscrew-assisted rapid palatal expander and aligners to correct bilateral cross-bite and crowding in an adult patient with a Class III skeletal pattern. A digitally designed surgical guide was three-dimensionally printed and used to accurately insert four miniscrews into the palate; these were employed to anchor a novel miniscrew-assisted rapid palatal expander appliance without any dental anchorage. Cone-beam computed tomograms before and after...

CONCLUSIONS: The use of a hybrid-anchorage expander followed by 4 months of facemask treatment improves the skeletal Class III relationship with minimal dental effects, even in older patients (mean age, 11 years 4 months, ± 2.5 years).

by Júnia Maria Serra-Negra on Gennaio 30, 2018 at 11:00 am

CONCLUSION: There was no association between possible SB and AB or the chronotype profiles among Italian dental students.

by Luca Lombardo on Novembre 14, 2017 at 11:00 am

CONCLUSIONS: Without the use of auxiliaries, orthodontic aligners are unable to achieve programmed movement with 100% predictability. In particular, although tipping movements were efficaciously achieved, especially at the molars and premolars, rotation of the lower canines was an extremely unpredictable movement.

by Luca Lombardo on Agosto 8, 2017 at 10:00 am

CONCLUSIONS: Of the nine cleaning strategies examined, only that involving 5 min of ultrasonication at 42 k Hz combined with a 0.3% germicidal cationic detergent was observed to be statistically effective at removing the bacterial biofilm from the surface of F22 aligners.

CONCLUSIONS: The expanders tested demonstrated stiffness characteristics compatible with opening of the palatine sutures in pre-adolescent patients. The stiffness of such devices can be further increased during the construction phase.

by Lucia Pisani on Settembre 13, 2016 at 10:00 am

CONCLUSIONS: A more robust approach to trial design in terms of methodology and error analysis is needed. Besides, more studies with longer periods of follow-up are required.

by Luca Lombardo on Settembre 6, 2016 at 10:00 am

CONCLUSIONS: The stiffness of an archwire is a function of its diameter, length and the alloy it is made from. In lower lingual wires, there is little difference in stiffness between mushroom and straight wires, but in upper wires, the straight version is considerably stiffer. The greater bearing effect exhibited by the straight wire in the working and finishing phases makes it less susceptible to bowing effect and therefore preferable for sliding mechanics during en masse retraction,...

CONCLUSIONS: Perceptions of dental esthetics can vary between dental professionals and laypersons. Investigating each patient's esthetic expectations is thus important, but in the patient's best interest, esthetic and functional aspects should be carefully weighed during comprehensive treatment planning.

by Angela Arreghini on Agosto 11, 2016 at 10:00 am

CONCLUSIONS: Compliance is generally very poor in young patients, regardless of their gender and psychological maturity. Although awareness of monitoring does not appear to boost compliance, such systems may be a valuable means of providing a dentist with objective information regarding their patients' compliance.

by Daniele Manfredini on Luglio 30, 2016 at 10:00 am

CONCLUSION: These findings support the study hypothesis only in part and confirm the absence of a clear-cut relationship between SB and psychological features.

by Luca Lombardo on Luglio 2, 2016 at 10:00 am

CONCLUSION: Although the Bolton index is useful for identifying dentodental discrepancies in most patients, cluster analysis enabled the mandibular and maxillary tooth dimensions of the male and female subjects to be divided into 3 general classes (clusters) and the precise location of the discrepancies to be pinpointed.

by Luca Lombardo on Giugno 18, 2016 at 10:00 am

CONCLUSIONS: Orthodontic aligner performance is strongly influenced by the material of their construction. Stress release, which may exceed 50% of the initial stress value in the early hours of wear, may cause significant changes in the behavior of the polymers at 24 hours from the application of orthodontic loads, which may influence programmed tooth movement.

by Luca Lombardo on Aprile 21, 2016 at 10:00 am

CONCLUSIONS: Our findings confirm that Class III patients have little periodontal support at the upper and lower incisors, irrespective of the amount of symphyseal leeway space available, and any tooth movement must therefore be carefully planned and monitored.

CONCLUSIONS: In archwires of the same cross-section, steel is always stiffer than TMA and NiTi, and super-tempered steel is always stiffer than conventional steels. In archwires of the same material, the stiffness increases with the cross-section, in particular with its height.

by Luca Lombardo on Novembre 20, 2015 at 11:00 am

CONCLUSIONS: Commercial aligners possess significantly different optical, and therefore aesthetic, properties, both as delivered and following aging.

by Luca Lombardo on Novembre 8, 2015 at 11:00 am

CONCLUSIONS: There are very significant differences in arch form between the two ethnic groups considered, and the range of pre-formed archwires on the market does not provide for the anatomical variability of patients.

by Daniele Manfredini on Ottobre 30, 2015 at 10:00 am

CONCLUSIONS: Findings confirmed the substantial absence of clinically significant effects of orthodontics as far as TMD is concerned. The very low correlation values of a negative or positive history of ideal or nonideal orthodontics with the different TMD diagnoses suggest that orthodontic treatment could not have a true role for TMD.

CONCLUSIONS: The quality of the available literature is not adequate to provide an evidence base on the topic. Despite the heterogeneity of design and findings of the reviewed articles, it seems reasonable to suggest that skeletal Class II profiles and hyperdivergent growth patterns are likely associated with an increased frequency of TMJ disc displacement and degenerative disorders.

by Luca Lombardo on Giugno 11, 2015 at 10:00 am

CONCLUSIONS: Race and ethnicity have a strong influence on values of tip, torque and in-out. This is translated as a more positive tip in Caucasian subjects and a more positive torque in those of African descent (greater proclination of the incisors). Finally, with respect to the values reported by Andrews, we found a tendency to more positive mean tip (except for at the upper second molars and lower incisors) and less negative torque in the posterior sectors.

by Silvana Allegrini Kairalla on Febbraio 27, 2015 at 11:00 am

CONCLUSION: The straight-wire arch shape used in the lingual straight wire technique is a parabolic-shaped arch, slightly flattened on its anterior portion. Due to similarity among dental arch sizes shown by males and females, a more simplified diagram chart was designed.

by Luca Lombardo on Novembre 28, 2014 at 11:00 am

CONCLUSIONS: The following prescriptions are advisable: tip 5°, torque 8° and in-out 2.5 for U1; tip 9°, torque 3° and in-out 3.25 for U3; tip 10°, torque -8° and in-out 3.75 for U4; and tip 5°, torque -8° and in-out 4 for U5. Andrews' prescription is suitable for the lower jaw, except for at L6. It is also advisable to execute selective grinding (1.33±0.5 mm) and extrusion (0.68±0.23 mm) on the upper canine during treatment, and the first premolar requires some intrusion (0.56±0.30 mm).

by Luca Lombardo on Novembre 19, 2014 at 11:00 am

CONCLUSIONS: The archwire-slot play was greater than the ideal for each archwire considered, inevitably leading to a loss of information within the system.

by Angela Arreghini on Ottobre 21, 2014 at 10:00 am

CONCLUSIONS: The dimensional precision of orthodontic brackets and archwires and the rigidity of the latter have a profound influence on the torque expression of pre-angled appliances.

CONCLUSIONS: Lingual vs. labial bracket placement influences the pattern of tooth movement, but the stress that occurs around the teeth can be accurately mapped using a 3D FEM model.

by Luca Lombardo on Dicembre 12, 2013 at 11:00 am

CONCLUSIONS: Friction resistance is influenced not only by the bracket type, type of ligation, and wire diameter but also by geometric differences in the brackets themselves.

by Luca Lombardo on Dicembre 12, 2013 at 11:00 am

CONCLUSIONS: Lingual and labial orthodontic appliances showed a different potential in modifying the investigated clinical parameters: patients wearing STb lingual orthodontic appliance had more plaque retention 4 and 8 weeks after bonding, while there were more gingival inflammation and more S. mutans counts 8 weeks after bonding. No differences were found between the two groups as regards the Lactobacillus counts, the salivary flow rate, and saliva buffer capacity.

by Luca Lombardo on Dicembre 12, 2013 at 11:00 am

CONCLUSIONS: In the present study, extractive orthodontic treatment appeared to predispose patients to a greater degree of root resorption. Indeed, the bone at the extraction site showed greater resorption in the study group with respect to the control group, and the appearance of intraosseous defects was noted in the former.

by Luca Lombardo on Novembre 26, 2013 at 11:00 am

CONCLUSIONS: None of the commercial archwires examined faithfully represented the shape of the 'ideal' dentition we calculated, particularly at the molars and canines. The bone structure of the mandibular support cannot be used as a guide to the shape of the arch form during orthodontic treatment.

CONCLUSIONS: No statistically significant differences in arch width were found between the different classes analysed (there are only slightly differences between classes), except in the case of mandibular inter-canine width (L3), which was smaller in Class I than in Class II,1, and maxillary inter-premolar width (U4), which was smaller in Class II-I than in Class I.

A 35-year-old female patient with dentoalveolar open bite of 4 mm, molar Class I malocclusion, centered midlines, moderate crowding, and labial inclination of the lower incisor was treated with clear aligners to reduce protrusion and close the anterior open bite. The result showed that clear aligners were an effective method with which to correct this malocclusion. The treatment was complete after 18 months. The patient was satisfied with her new appearance and function.

A 13-year-old girl came with the chief complaint of an unesthetic dental appearance. Her maxillary canines were bilaterally impacted. Treatment included extraction of the maxillary canines and the mandibular second premolars. The maxillary first premolars were substituted for the canines. After 26 months of active treatment, the patient had a Class I molar relationship and ideal overbite and overjet. Her profile was improved, lips were competent, and gingival levels were acceptable....

Although evident advances have certainly been made, not only in the use of brackets, but also in the mechanics and type of wires and accessories employed, the most recent systematic review of the literature on this topic stated despite claims regarding the clinical superiority of self-ligating brackets, evidence is generally lacking. Thus, the aim of this study was to show, by means of four clinical case reports, that conventional brackets, used in conjunction with relatively recently introduced...

CONCLUSIONS: Application of an intrusive lingual force to a lower incisor appears to generate bodily movement, while the same intrusive labial force appears to lead to labial tipping. Subject to further study, this should be taken into consideration when devising treatment plans for fixed appliances.

by Dominique Toscano on Agosto 28, 2012 at 10:00 am

CONCLUSIONS: It seems appropriate to recommend early application of a surgical-orthodontic protocol to treat cleft lip and palate patients, prevent postoperative bone resorption, and guarantee correct positioning of the teeth.

by Davide Mirabella on Agosto 28, 2012 at 10:00 am

CONCLUSIONS: The results of this study highlight great variability among the patients studied, and suggest that the behaviour of the soft tissues (lower lip changes) following displacement of the upper and lower incisors is multifactorial and very difficult to predict.

by Luca Lombardo on Agosto 23, 2012 at 10:00 am

CONCLUSIONS: All nickel-titanium wires tested showed a significant change related to temperature in terms of behavior and force for both traditional and heat-activated wires. Stress under high temperatures can induce permanent strain, whereas the residual strain detected at low temperatures can be recovered from as temperature increases.

by Antonio Gracco on Agosto 4, 2012 at 10:00 am

CONCLUSIONS: Analysis of the results showed that there are no significant differences between perceptions, sensations and judgments related to smiles presented either as part of the whole face or in only the lower facial third: general facial attractiveness does not influence evaluations of the smile. The study confirms the general tendency to award higher scores to smiles with normal alignment.

by Luca Lombardo on Febbraio 3, 2012 at 11:00 am

CONCLUSION: This study showed that there are no different perceptions and sensations due to the variation of dental alignment. There is a general trend in the classification of smiles according to dental alignment. Background attractiveness and sexual traits influenced the judgment of smile.

by Luca Lombardo on Ottobre 25, 2011 at 10:00 am

CONCLUSION: Overall, STB brackets performed better, and sandblasting proved to be an efficient way of improving the mechanical features of lingual brackets. Bonding technique, on the other hand, did not seem to exert a great influence on bonding success, and the bracket-adhesive interface was identified as the area most prone to failure.

by Luca Lombardo on Settembre 15, 2011 at 10:00 am

CONCLUSIONS: Although great variation was seen in the plateau behavior, heat-activated versions appear to generate lighter forces over greater deflection plateaus. On average, the increase in plateau force was roughly 50% when the diameter was increased by 0.002 inch (from 0.012 to 0.014 and from 0.014 to 0.016 inch) and about 150% when the diameter was increased by 0.004 inch (from 0.012 to 0.016), with differences between traditional and heat-activated wires noted in this case.

by Antonio Gracco on Maggio 3, 2011 at 10:00 am

CONCLUSION: The CBCT data obtained permitted identification of the alveolar anatomy and quantification of the intrusion possible. In the older age group, potential intrusion was significantly greater for teeth 12, 21 and 22. Furthermore, a directly proportional relationship between the measurements pertaining to each tooth in a single patient was noted.

CONCLUSIONS: The research suggested that Italian orthodontists were less prone to Burnout Syndrome compared to general dentists. As life-style has a major impact on the onset of the syndrome, preventive measures and solutions could be useful in order to prevent the symptoms of the Burnout Syndrome.

Today a lot of minor cosmetic surgery operations on the gingiva can easily be carried out directly by the orthodontist with a small quantity of topical anaesthetic and the use of a soft tissue laser. The Diode laser is the most commonly used laser in dentistry for minor surgery to the soft tissues. This kind of laser offers numerous advantages with respect to traditional or electric scalpels. In this article the authors will analyse several typical uses of the diode laser in daily orthodontic...

CONCLUSIONS: The distal screw anchored by two palatal mini-implants allows not only translatory molar distal movement, but also distal movement of the maxillary first premolars, thereby avoiding characteristic anchorage loss.

A 23-year-old woman with a skeletal Class III relationship, a normal vertical jaw relationship, and missing maxillary lateral incisors was treated with bidimensional fixed edgewise appliance therapy combined with orthognathic surgery. A functional and esthetic occlusion in an improved facial profile was established at the end of the surgical and orthodontic treatment. Pretreatment, posttreatment, and long-term follow-up records for the patient are presented.

by Luca Lombardo on Febbraio 5, 2011 at 11:00 am

CONCLUSION: The initial hypothesis was supported. Because of the reduced interbracket distance, the adoption of superelastic wires is required in lingual mechanics and with smaller diameter compared to labial mechanotherapy, in particular during the first phases of treatment. The use of a bracket with reduced mesiodistal dimensions can contribute to reduce the load on the teeth.

by Domizia Di Fazio on Gennaio 4, 2011 at 11:00 am

CONCLUSIONS: In healthy patients, (1) upper lip pressure does not change at rest and during swallowing, (2) upper lip pressure was similar in the 2 groups (Class I, 24.33 g/cm(2); Class II, 24.61 g/cm(2)), and (3) lip pressure was higher in adults than in young subjects. Further studies are needed to measure the pressure of the lower lip and to evaluate whether there are differences in labial pressure between subjects with labial competence and incompetence.

by Luca Lombardo on Settembre 7, 2010 at 10:00 am

CONCLUSIONS: Three lingual curves (small, medium, and large) for the maxillary and mandibular arches, representing the mean values of our sample, were developed and can be used as guides for the setup in the lingual straight-wire technique.

Odontodysplasia of the third molars is a relatively common anomaly. The frequent complications associated with this disorder very often constitute an indication for extraction of the third molar. This surgical treatment can damage the lower alveolar nerve and/or trigger distal bone loss of the second molar, thus jeopardizing the future status of the periodontium. The author presents two case studies treated exclusively with miniscrews with no dental anchorage in order to achieve partial eruption...

The mushroom arch-wire is mainly used in lingual orthodontic treatment but the complicated wire bending it requires affects both the treatment results and the time spent at the chair. The author proposes a new lingual straight wire method (LSW) in order to facilitate arch coordination and simplify the mechanics. The attention paid to the set-up model and bracket positioning and bonding plus the use of the new LSW method will also improve patient comfort.

by Luca Lombardo on Ottobre 27, 2009 at 10:00 am

CONCLUSIONS: The hypothesis is rejected. Miniscrews loaded within the normal orthodontic force range do not exceed the stress levels that lead to bone fracture.

The purpose of this research was to evaluate changes in upper arch dimension and form following rapid maxillary expansion (RME) using a modified Haas appliance in the primary dentition. The sample comprised 49 children [17 males, 32 females, mean age 7 years 5 months, standard deviation (SD) 1 year 1 month] with a crossbite or maxillary crowding. Twenty patients had a normal SN-GoGn angle (7 males, 13 females, mean 33.25 degrees, SD 2.10), three were low angle (1 male, 2 females, mean 27.67...

INTRODUCTION: In this study, we aimed to analyze the displacement field and the level of stability for a human mandible that had symphyseal distraction osteogenesis. The mandible was fitted with various orthodontic devices: tooth borne, bone borne, and hybrid. Three-dimensional nonlinear finite element analyses were performed to study differences between the nominal aperture of the device and the actual mandibular distraction. Furthermore, displacement fields of the mandibular arch evaluated...
