OBJECTIVE This study compared the effects of three different methods of preparing bone implant sockets (drilling, osteotomes, and piezoelectric device) on osseointegration using resonance frequency analysis (RFA). STUDY DESIGN An experimental prospective study was designed. MATERIAL AND METHODS Ten adult beagle dogs were studied. After 5 weeks, 23 out of 28 initially placed implants in the ...

BACKGROUND This study evaluated the influence of implant site preparation depth on primary stability measured by insertion torque and resonance frequency analysis (RFA). MATERIAL AND METHODS Thirty-two implant sites were prepared in eight veal rib blocks. Sixteen sites were prepared using the conventional drilling sequence recommended by the manufacturer to a working depth of 10mm. The remain...

OBJECTIVES Implant primary stability is one of the important factors in achieving implant success. The osteotome technique may improve primary stability in patients with poor bone quality. The aim of this study was to compare implant stability using two different techniques namely osteotome versus conventional drilling in the posterior maxilla. MATERIALS AND METHODS In this controlled randomi...

A highly skilled surgical technic is an important factor for the success of implant. But the heat generation during bone preparation will greatly affect the healing process of bone and prognosis of implant. In this study, the heat occurrence and distribution during bone preparation which performed on an in vitro mandible model (ribs of pig) were considered with the aid of a real-time thermograp...

Up to date, zygomatic implants (ZIs) have been considered a predictable treatment modality for cases of atrophic maxilla. In some severe cases with severe vertical and/or horizontal bone resorption in the anterior maxilla, the placement of standard implants in the anterior area represents a challenge. In these arduous scenarios, performance of a zygomatic "quad-approach" might be advocated. Nev...

Drilling of the skull base bone without damaging the important inside structures and with the correct orientation is very difficult even with the help of the anatomical landmarks. Monitoring of the location and direction of the drill tip and indications of the removed part of the bone during the drilling procedure enhances safety and achieves less invasive neurosurgery. We have developed a nove...

Osteochondral lesions are drilled with the aim of stimulating the growth of new cartilage to cover the defect (Pnidie 1959). This may be performed at arthrotomy or anthroscopically, but arthroscopic drilling is far from standard practice. Performed percutaneously, arthroscopic drilling by Kirschner wire can be hindered by difficulty with accurate placement, skidding off sclerotic bone and entan...

Insufficiency fractures secondary to prolonged alendronate use is due to inhibition of osteoclastic activity and suppressed bone turnover. Complications of fracture fixation include non-union, mal-union, and difficulty in intramedullary nail insertion. We report a technical challenge in intramedullary nailing of an obliterated femoral canal in a patient on long-term bisphosphonate treatment. Th...

RATIONALE Retrograde drilling is a well accepted procedure for osteochondral lesion of the talus and subchondral cyst with intact overlying cartilage. It has good results in most reports. Compared to anterograde drilling, retrograde drilling can protect the integrity of the articular cartilage. The purpose of this study was to evaluate the suitability of using retrograde drilling for osteochond...

AIM This study aimed to evaluate the length of the holes drilled for the placement of zygomatic implants using two surgical techniques: the original Brånemark and the Exteriorized (extrasinus) protocols. The most frequent implant length used and position where the implants emerged in the zygomatic bone were recorded. MATERIALS AND METHODS Both surgical techniques for inserting zygomatic impla...
