Abstract
Molar extrusion is a quite common problem in prosthodontic patients. It is caused due to the loss or infraocclusion of opposing teeth. A more conservative approach than reduction of the coronal part of extruded tooth is to intrude the malaligned molar orthodontically. Several authors have presented the cases of molar intrusion, by cither removable or fixed appliances. However, the design of those appliances was complex so that many teeth were included as an anchorage unit. This increased the patient's discomfort inevitably. Moreover, the results could be unpredictable. Instead of these conventional methods, skeletal anchorage has been suggested for ideal force system to intrude a molar without any side effects. Many recent clinical reports presented the cases using microscrew or miniplate as a direct anchorage, which included some limitation. The purpose of this report is to introduce the indirect skeletal anchorage for intrusion of extruded maxillary molar.
