15 صفحه اولHigh Force Levels Can Be Delivered With Thermoplastic Aligners Initial Forces Generated by Three Types of Thermoplastic Appliances on an Upper Central Incisor During Tipping
Background: Treatment of minor malocclusions with clear thermoplastic aligners is more commonly being used as an aesthetic alternative to fixed appliances. This can be done by manually resetting teeth on a plaster model or by models generated from a 3D computer model (Invisalign®). However, little research has been performed on the complex force systems generated by these types of appliances. O...
متن کاملInitial forces generated by three types of thermoplastic appliances on an upper central incisor during tipping.
The force properties of thermoformed appliances have not been systematically investigated. Therefore, the aim of the present study was to quantify the forces delivered by thermoplastic appliances manufactured from three different materials, with the same thickness, on a central upper incisor, during tipping. Five identical appliances were manufactured from three different materials all with a t...
متن کاملForces and moments generated by removable thermoplastic aligners.
INTRODUCTION The exact force systems as well as their progressions generated by removable thermoplastic appliances have not been investigated. Thus, the purposes of this experimental study were to quantify the forces and moments delivered by a single aligner and a series of aligners (Invisalign; Align Technology, Santa Clara, Calif) and to investigate the influence of attachments and power ridg...
