TADS vs osseointegrated implants in orthodontic skeletal anchorage

Aims: This clinical evaluation showed the benefits, possibilities and limits of Temporary Anchorage Devices system (TADs) to obtain a rigid skeletal anchorage for tooth movements. These were compared to osseointegrated implants, used as orthodontic anchorage. Materials and Methods: The study utilized 88 patients, 51 men and 37 women, aged 20 to 49 years. Were inserted 84 mini-implants and 44 fixtures to control anchorage. The mini-implant system consisted of a pure titanium micro anchor screw and an abutment hook. Results: The use of mini-implants as anchorage in tooth movement, produced a satisfactory result in a short period of time. This is very important for preventing dental, periodontal, esthetical and psychological problems during orthodontic treatment. Teeth can be moved more efficiently because force can be applied directly in the direction of the position indicated by the treatment objectives. Conclusions: The new type of anchorage system has overcome the biomechanical limitations of conventional orthodontic mechanotherapy in terms of anchorage. The entire dentition can be moved at one time because the problems related to anchorage are resolved. The teeth can be simultaneously moved theree-dimensionally for several treatment objectives, and simplifies control of asymmetric mechanics. The use of mini-implants as temporary anchorage enables to insert an appliance in any aimed position and carries out easily the tooth movement.
