Statement: Osteotomies are well-established procedures in oral and maxillofacial surgery for either corrective measures or for gaining access to subjacent hard and soft tissues. Yet surgical reconstruction of bony defects can often be very challenging as thin and fragile bony structures are especially prone to fracture due to bulky cutting tips or massive application of pressure by conventional...

BACKGROUND Multiple small drilling for core decompression is widely used to preserve the femoral head in patients with avascular necrosis of the femoral head (ANFH). Nevertheless, the clinical outcome remains controversial. Simvastatin has been demonstrated to promote bone formation and reduce bone adsorption. The purpose of this study was to determine whether simvastatin enhanced the effect of...

BACKGROUND To evaluate the effects of the amount of irrigation on heat generated during implant site preparation. MATERIAL AND METHODS Ten freshly dissected sheep mandibles were sectioned into 30 equal bone blocks and transferred into a heat-controlled water tank. Implant socket preparations were performed with four consecutive drills. Temperature measurements were performed with a thermocoup...

This reviews objective is to inform readers of a creative substitute for traditional drilling techniques that keeps host bone in the greatest possible biological shape implant placement. 4 Optic and electronic microscopy have also demonstrated obtained through this method live bone. crucial since clinical studies indicated autogenous best filler defects. gathering may make it easier manipulate ...

BACKGROUND Graft fixation is critical to the restoration of the medial patella of femoral ligament function and long-term success. Numerous fixations at the patella have been described, while the complications including patellar fractures, violation of the posterior patella and delay of tendon-to-bone healing remain significant challenges. Here, we describe a safe and firm fixation at the patel...

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...

This paper studies a position feedback control strategy for controlling a higher order drifting oscillator which could be used in modelling vibro-impact drilling. Special attention is given to two control issues, eliminating bistability and suppressing chaos, which may cause inefficient and unstable drilling. Numerical continuation methods implemented via the continuation platform COCO are adop...

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...
