2016 AAO Annual Session - Complex Space Closure of Missing Teeth with TADs / Simplified Mechanics for Challenging Adult Cases

Complex Space Closure of Missing Teeth with TADs

A missing tooth can offer bold challenges to orthodontic treatment. The treatment plan can include the maintenance of space for rehabilitation by an implant-supported prosthesis. However, in many cases it might be advantageous to close the space, especially when the gap closure provides superior esthetic results, or when the patient simply does not want to receive implant rehabilitation. Commonly, the use of TADs as anchorage is beneficial to the latter form of treatment. In some cases the TAD, be it a miniplate or a mini-screw, is crucial to achieve excellent treatment results, and then the applied orthodontic mechanics have several specificities. This lecture will tackle the treatment protocol used to close the space of missing teeth with miniplates, as well as the advantages and limitations of this treatment modality.

After this lecture you will be able to:

• Recognize the indications of closing the space of missing teeth
• Determine the proper TAD position for the orthodontic mechanics
• Distinguish the advantages of space closure in comparison to the implant rehabilitation

Simplified Mechanics for Challenging Adult Cases

Adult patients are often presented with malocclusions and a wide range of additional complex challenges. Orthodontic treatment can improve occlusal functions while paving the way for subsequent periodontal, restorative care and implant surgeries. This lecture aims to demonstrate how to design simplified mechanics to treat gummy smile, impaction, sagittal discrepancy and a variety of other compounding issues.

After this lecture you will be able to:

• Identify common adult patients’ treatment needs
• Determine the sequence of treatment involving multiple specialties for complex adult patients
• Design simplified mechanism using miniscrews to solve three-dimensional problems
