INTRODUCTION Current studies have compared indirect bonding with direct placement of orthodontic brackets; many of these have shown that indirect bonding is generally a more accurate technique. However, the reproducibility of an indirect bonding setup by an orthodontist has yet to be described in the literature. Using cone-beam computed tomography and computer-assisted modeling software, we eva...

The slots of five upper left central incisor brackets from 11 commercially available bracket systems (3M Unitek, Monrovia, Calif: Twin Torque Roth, Clarity MBT, and Victory Series MBT; Dentarum, Pforzheim, Germany: Discovery Roth (0.56 mm) and Elegance Plastic Roth; Forestadent, Pforzheim, Germany: Mini Mono MBT; TP LaPorte, Indiana: Nu-Edge Roth and Mxi Advant-Edge Roth; Ormco Corp., Orange, C...

The convergence of computer-aided technology and dental implant has shown that dynamic navigation can effectively improve the accuracy reliability clinical placement. To address this, a system for oral surgery based on Mixed Reality (MR) been developed. Using standard dentition experimental model, stability linear curved positioning tracking brackets was studied by constructing real-time monito...

duced in the early 1970s, used conventional labial brackets that were modified by the clinician and bonded directly to the lingual surfaces. Brackets designed specifically for lingual usage1-4 were initially prone to technical problems that made them difficult to use in everyday practice. The development of indirect bonding permitted more precise lingual bracket positioning and reduced the chai...

BACKGROUND The basic premise of preadjusted bracket system is accurate bracket positioning. It is widely recognized that accurate bracket placement is of critical importance in the efficient application of biomechanics and in realizing the full potential of a preadjusted edgewise appliance. AIM The purpose of this study was to design a calibrating system to accurately detect a point on a plan...

Introduction: Torque in orthodontics is vital in final positioning of the teeth during fixed appliance therapy. Torqueing of archwires is a significant factor in transferring the applied forces to the bracket which might cause deformation of the slot. Any deformation in the bracket slot can vary the torque prescription and thus can affect the tooth position. Aim: To evaluate and compare the def...

To improve the accuracy of bracket placement in vivo, a protocol and device were introduced, which consisted operative procedures for accurate control, computer-aided design, an augmented reality–assisted navigation system. The present study evaluated this protocol. Methods: Thirty-one incisor teeth tested from four participators. bonded by novice expert orthodontists. Compared with control gro...

The front bracket of a certain type studied in this subject is part the braking system and plays an important role system. main parts support are grooved surface, 44.3mm cylindrical M16 threaded hole plane, Ф 12 holes 2.5mm grooves. These matched with brake plate, so they have high dimensional accuracy geometric accuracy. content paper to optimize positioning scheme when machining height 2mm gr...

INTRODUCTION The indirect bonding technique optimizes fixed appliance installation at the orthodontic office, ensuring precise bracket positioning, among other advantages. In this laboratory clinical phase, material and methods employed in creating the transfer tray are decisive to accuracy. OBJECTIVE This article describes a simple, efficient and reproducible indirect bonding technique that ...
