Abstract
Abstract: Aim of the study: To evaluate the efficacy of two different techniques for maxillary alveolar ridge expansion, the osteotome and screwexpander. Patients and methods: This study was carried out on 16 healthy male patients received 16 implants. Average age 40 years. Each patient has partial edentulous maxilla with bone width not less than 4 mm and height not less than 10 mm. The patients were divided into two equal groups. In group I, implant site was prepared by osteotomes of increasing diameter to reach the planned osteotomy width, group II, implant site was prepared by expansion screws of increasing diameter to reach the planned osteotomy width. Clinical evaluation was done 24 hours postoperatively for edema, wound dehiscence, pain and signs of infection and regular checkups were done weekly during the first month. Radiographic evaluation using CBCT was done after 3 and 9 months postoperatively to measure bone density around inserted implants and vertical bone loss. Implant stability was measured by using Osstell ISQ device for all the implants of the two groups after 6 months (before loading) and after 9 months. Results: Radiographic evaluation showed significant higher bone density and lesser vertical bone loss around the inserted implants in group I than in group II after 3 and 9 months. Also, implant stability measurements at six and nine months showed highly significant values in group I more than in group II. Conclusion: Maxillary alveolar ridge expansion with osteotome is superior to screwexpander regarding to bone density and osseointegration.
