statement of problem: as a physical property, wear resistance of the materials used in the fabrication of orthodontic retainers play a significant role in the stability and long term use of the appliances. objectives: to evaluate the wear resistance of two commonly used materials for orthodontic retainers: acropars op, i.e. a polymethyl methacrylate based material, and 3a-gs060, i.e. a polyethy...

OBJECTIVE The aim of this study was to evaluate retention practices commonly employed by orthodontists. The objectives were to identify the types of retainer frequently used and to investigate the variations in retention practice. METHODS A total of 97 orthodontists were randomly selected, and a questionnaire consisting of 25 multiple-choice questions sent to them by mail. Upon receiving of t...

Clear thermoplastic retainers have been widely used in daily orthodontics; however, they have inherent limitations associated with thermoplastic polymer materials such as dimensional instability, low strength, and poor wear resistance. To solve these problems, we developed a new type of clear orthodontic retainer that incorporates multi-layer hybrid materials. It consists of three layers; an ou...

OBJECTIVE To test the null hypothesis that orthodontist characteristics and factors related to retainer choice do not influence the management of the retention phase with regard to frequency and duration of follow-up care provided. MATERIALS AND METHODS Orthodontists (n  =  1000) were randomly selected to participate in an online survey divided into three categories: background, retainer choi...

Retainer care arrangements allow patients to pay a retainer directly to a physician's office in order to obtain special access to care.' Practices usually convert to retainer status by focusing their attention on those willing to pay a retainer fee, and dropping the majority of their patients, who are left to be absorbed by other practices.2 Also known as "boutique medicine," "concierge care," ...

Background: Major goal of orthodontic treatment is long term stability the corrected teeth after treatment. After there always chance relapse. To prevent relapse several appliances are available as a retention device such bonded fixed retainers, vacuum formed removable Hawley retainer, Begg’s retainer. Now days retainer has become more acceptable due to low cost, esthetic and easy fabrication. ...
