Temporary anchorage devices -Mini-implants

Mini-screw implants (temporary anchorage devices): orthodontic and pre-prosthetic applications.

Mini-screw implants, often referred to as temporary anchorage devices (TADs), have become an accepted component of orthodontic treatment. The comparatively simple technique for the placement of these mini-screws is described with emphasis on the importance of correct site selection as well as an understanding of the possible complications that may arise. The application and description of appli...

The Use of Mini-Implants (Temporary Anchorage Devices) in Resolving Orthodontic Problems

Experience with orthodontic temporary anchorage devices

In orthodontics, anchorage is a prerequisite for the application of therapeutic forces and can limit their successful use. According to the intended treatment goals, desired tooth movements should, therefore, be maximized and undesirable effects minimized. But additional anchorage such as extraand intraoral forces are visible and hence compliance dependent and are associated with the risk of un...

Corrosion of orthodontic temporary anchorage devices.

Corrosion of orthodontic miniscrews or temporary anchorage devices (TADs) has been proposed as a contributor to inflammation, which in turn is a factor in the clinical success of miniscrews. The purpose of this study was to measure the electrochemical properties of orthodontic miniscrews in artificial saliva with and without fluoride. The corrosion properties of three miniscrew products (Vector...

Mandibular molar protraction with temporary anchorage devices.

351 P of mandibular molars is challenging because of the high density of mandibular bone. Anterior dental anchorage is often inadequate to protract even a single first molar without reciprocal retraction of the incisors or movement of the dental midline. Furthermore, if the buccal and lingual cortical plates in the edentulous region have collapsed, safe and effective protraction may be impossib...
