Noncompliance screw supported maxillary molar distalization in a parallel manner

Abstract

Objective: Intraoral noncompliance upper molar distalization techniques have gained in popularity and have subsequently found to be successful in Class II correction. The aim of the present study was to introduce a screw supported intraoral distalization appliance and investigate its efficiency. Methods: Twenty-one subjects (11 females, 10 males; average age of 14.9 years) with Angle Class II malocclusion participated in this study. Two screws were inserted behind the incisive foramen and immediately loaded to distalize the upper first molars. An intraoral screw supported distalization appliance was used to distalize the upper molars in order to achieve a Class I molar relationship. Skeletal and dental changes were evaluated using cephalometric and three-dimensional (3D) model analysis. Results: Upper molars were distalized 3.95 mm on average and a Class I molar relationship was achieved without any anchorage loss. The upper molars were tipped only 1.

Zygoma-Gear Apareyi ile Maksiller Molar Distalizasyonunun Maksiller Üçüncü Molar Dişler Üzerine Etkileri

“…Fakat literatürde birinci molarların distalizasyonu sırasında maksiller üçüncü molar dişlerin pozisyonu ve angulasyonu ile ilişkili araştırma bulunmamaktadır. Araştırıcıların çoğu (12)(13)(14), distalizasyon öncesinde üçüncü molar dişleri çekmişlerdir ve distalizasyon öncesinde üçüncü molar dişlerin çekimini genellikle önermişlerdir. Bu nedenle distalizasyon mekaniklerinin maksiller üçüncü molar dişleri üzerindeki etkilerini inceleyen az çalışma mevcuttur (15)(16)(17).…”

“…However, the position and angulation of the maxillary third molars when distalizing the first molars was not investigated in the literature. Most of the authors (12)(13)(14) have the maxillary third molars extracted prior to the distalization and the extraction of the third molars before distalization is usually recommended (12)(13)(14). Thus few studies (15)(16)(17) Maksiller birinci molarların bilateral distalizasyonu için çalışmada kullanılan aparey, zigomatik ankraj plakları ile kombine edilen ağız içi bir distalizasyon mekaniğidir.…”

A reliable method for evaluating upper molar distalization: Superimposition of three-dimensional digital models

“…To correct a molar relationship or crowding, molar distalization is frequently performed with various appliances. 10 , 11 To assess the efficacy of these appliances, superimpositions of serial cephalometric radiographs, study model photographs, and photocopies have been used in previous studies. 10 , 12 To our knowledge, there is no study that compares the superimposition of 3D digital models with cephalometric radiography and model photocopy methods in cases of molar distalization.…”

Various Contemporary Intraoral Anchorage Mechanics Supported with Temporary Anchorage Devices

“…Using this device, bodily distalization of the molars can be achieved by applying the force at the level of its center of resistance. The distal tipping of the molars with this appliance has been reported to be 149 degrees in a previous study, while with other mini-implant-supported distalization mechanics, it has been reported to be 3 to 11.3 degrees (19,20). TSADRME, MISME, Implant-Supported RME, and Hybrid Hyrax: These appliances are various types of the Hyrax (Hyrax®; Dentaurum; Ispringen, Germany) type maxillary palatal expander.…”
