The low bone density of the posterior maxilla presents a challenge forimplant treatment and lower success rates compared to other regions of higherbone quality as the anterior region of the mandible was observed. Improving thelocal bone properties by surgical means is of a particular interest at sites of reducedbone density. Therefore the use of the osteotome technique to locally optimize thelocal bone density and consequently improving the primary implant stability wasproposed. The aim of the present study was to evaluate clinically andradiographically the osteogenesis around the implants placed in the posterior partof the maxilla by using the osteotome versus the conventional drilling techniques.This study was conducted on eight adult partially edentulous patients selectedaccording to a predefined criteria .Ages ranged from 27- 43 years old, from bothsexes (five females and three males), for each patient two implants were installedbilaterally in the posterior maxilla utilizing the osteotome technique on one sideand the conventional drilling technique on the other. Clinical and radiographicassessment was done immediately after implant loading, then at three and sixmonths after loading. The Plaque index was measured according to (Leo 1967),the Gingival index according to Leo and Sillness (1963) gingival index score andthe Probing depths were recorded by a graduated periodontal probe.Radiographic evaluation was done utilizing digital panoramic radiographs with amagnification factor of 1:1 to perform Bone density measurements (Densitometricanalysis) and Bone height measurements (Linear analysis) using The software ofthe Digora system. The conclusions of the present study have proven that theosteotome technique for implant bed preparation is superior for application insofter maxillary bone as it enhances bone density and may reduce crestal bone lossafter implant loading in low density bone, better than the conventional drillingtechnique for implant bed preparation.
