pubmed

Prog Orthod. 2019 Jan 7;20(1):1. doi: 10.1186/s40510-018-0251-z. ABSTRACT OBJECTIVES: The aim of this study is to investigate and compare the characteristics of as received and retrieved NiTi archwires at a constant temperature by plotting their load/deflection graphs and quantifying three parameters describing the discharge plateau phase. MATERIALS AND METHODS: Two hundred four NiTi archwires, traditional…

Self-reported AB as well as information on sleep characteristics were collected from a questionnaire. The…

Correlation Between Sleep-Time Masseter Muscle Activity and Tooth Wear: An Electromyographic Study

pubmed

J Oral Facial Pain Headache. 2019 Spring;33(2):199-204. doi: 10.11607/ofph.2081. ABSTRACT AIMS: To assess the correlation between tooth wear and sleep-time masseter muscle activity (sMMA) in a group of healthy young adults who underwent home electromyographic/electrocardiographic (EMG/ECG) recordings with a portable device. METHODS: A total of 41 healthy volunteers (23 women, 18 men; mean age 28.8…

Marsupialization of a dentigerous cyst followed by orthodontic traction of two retained teeth: A case report

pubmed

Int Orthod. 2019 Jun;17(2):365-374. doi: 10.1016/j.ortho.2019.03.019. Epub 2019 Apr 22. ABSTRACT 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…

Experimental Study of the Pressures and Points of Application of the Forces Exerted between Aligner and Tooth

pubmed

Nanomaterials (Basel). 2019 Jul 12;9(7):1010. doi: 10.3390/nano9071010. ABSTRACT The analysis of forces, moments and pressure points has long been of great interest in orthodontics. Hence, we set out to define a method for measuring the pressure exerted by aligners on the teeth, and specifically to identify the precise points of pressure exertion. Intraoral scans were…
