Association of the mid-palatal suture morphology to the age and to its density: A CBCT retrospective comparative observational study

pubmed

Int Orthod. 2021 Jun;19(2):235-242. doi: 10.1016/j.ortho.2021.03.002. Epub 2021 Mar 27. ABSTRACT OBJECTIVE: The twofold aim of the present investigation was to: 1. evaluate the degree of mid-palatal suture (MPS) maturation via CBCT in relation to patient age, and 2. to determine whether there was a correlation between quantitative (i.e., suture density) and qualitative (i.e., suture…

Micro-computed tomography evaluation of general trends in aligner thickness and gap width after thermoforming procedures involving six commercial clear aligners: An in vitro study

pubmed

Korean J Orthod. 2021 Mar 25;51(2):135-141. doi: 10.4041/kjod.2021.51.2.135. ABSTRACT OBJECTIVE: To assess the effects of thermoforming on aligner thickness and gap width in six aligner systems with the same nominal thickness. METHODS: Six passive upper aligners of different brands were adapted to a single printed cast. Each sample was evaluated with high-resolution micro-computed tomography. To…

Dual-section versus conventional archwire for en-masse retraction of anterior teeth with direct skeletal anchorage: a finite element analysis

pubmed

BMC Oral Health. 2021 Feb 25;21(1):87. doi: 10.1186/s12903-021-01443-0. ABSTRACT BACKGROUND: The aim of this study is to compare the biomechanical effects of the conventional 0.019 × 0.025-in stainless steel archwire with the dual-section archwire when en-masse retraction is performed with sliding mechanics and skeletal anchorage. METHODS: Models of maxillary dentition equipped with the 0.019 ×…

Class II subdivision with skeletal transverse maxillary deficit treated by single-sitting bone-borne appliance

pubmed

Angle Orthod. 2021 Jan 1;91(1):129-137. doi: 10.2319/050520-394.1. ABSTRACT This case report describes orthodontic treatment including both skeletal maxillary expansion and unilateral distalization by means of a single bone-borne appliance followed by clear aligner therapy in a young adult patient. A surgical guide was digitally designed and three-dimensionally printed to facilitate the placement of four miniscrews…

Cephalometric analysis of dental and skeletal effects of Carriere Motion 3D appliance for Class II malocclusion

pubmed

Am J Orthod Dentofacial Orthop. 2022 Jan 4:S0889-5406(21)00796-4. doi: 10.1016/j.ajodo.2020.12.024. Online ahead of print. ABSTRACT INTRODUCTION: The objective was to describe the dental and skeletal changes obtained using the Carriere Motion Appliance (CMA), lateral cephalogram, and the corresponding cephalometric tracings. METHODS: A sample of 29 patients with Class II malocclusion (mean age, 12.6 ± 1.7…

Detailed three-dimensional orthodontic tooth repositioning to improve restorative outcome

pubmed

Angle Orthod. 2021 Dec 30. doi: 10.2319/061721-487.1. Online ahead of print. ABSTRACT The case describes the interdisciplinary treatment of a 23-year-old woman with a Class III malocclusion, missing an upper right lateral incisor, abrasion of the maxillary incisal edges, anterior gingival margin discrepancies, and gingival recession. Initially, the patient was treated with fixed appliances combined…

Severe transverse discrepancy in adult Class III patient: Parallel rapid palatal expansion with a bone-borne tandem expansion screws (TSE) followed by lingual fixed appliance for a non-surgical treatment: A case report

pubmed

Int Orthod. 2021 Dec 3:S1761-7227(21)00144-3. doi: 10.1016/j.ortho.2021.11.001. Online ahead of print. ABSTRACT INTRODUCTION: Midpalatal suture opening in young adults is often difficult to achieve, depending on the suture maturation stage. It has been suggested that it is possible to avoid surgery and still achieve a successful pure skeletal expansion if a bone-borne Miniscrew-Assisted Rapid Palatal…

Resolution of lower second molar impaction through miniscrew-supported biomechanics: A proposal for a simplified classification
