Anatomic factors include decreased bone quantity, especially in older edentulous or partially edentulous patients who have experienced alveolar resorption in the wake of tooth loss. The antrum also tends to enlarge with age, as well as with edentulism, and this further decreases the amount of available bone. In addition to the diminished quantity, bone in the posterior maxilla often is softer a...

Atraumatic preparation of the recipient site has been considered an important factor influencing implant survival. Heat generation during bone drilling has been reported to be related to various factors. The methodology for heat assessment and bone examination together with the osseous models are still points of great speculation. The present paper classifies and discusses some of those factors...

Introduction: Compaction of bone to create a cavity for a total joint implant is gaining recognition as a bone-saving alternative to methods of cavity preparation that involve only extraction of bone. Advantages of compaction are increased contact area at the implant-bone interface and subsequent improved initial fixation and potential for bone ingrowth. Rasping and drilling are bone extraction...

PURPOSE Unlike standard dental implants, the stabilization of orthodontic microscrews removed after treatment is done without osseointegration and achieved by several components: cortical bone thickness (CBT), microscrew geometry, and drilling depth. The purpose of this study was to evaluate 10 different microscrews and the influence of their geometric parameters with different CBT and drilling...

BACKGROUND Treatment of tibial stress fractures in elite dancers is centered on rest and activity modification. Surgical intervention in refractory cases has important implications affecting the dancers' careers. HYPOTHESIS Refractory tibial stress fractures in dancers can be treated successfully with drilling and bone grafting or intramedullary nailing. STUDY DESIGN Case series; Level of e...

*Department of P.O.P, college of dentistry, university of Mosul, Mosul, Iraq. Introduction Conservation of anchorage in totality has been a perennial problem to the traditional orthodontist. Conventional means of supporting anchorage have been used by either intra oral sites or relying on extra oral means. Both of these have their limitations. The extra oral forces very difficult device and som...
