| Abstract | ||
| ABSTRACT Background: The lateral approach for sinus floor augmentation using the trephine-osteotomy is a precise surgical technique. For the time being, in implant dentistry, trephine drills have been used instead of conventional drills to conserve the bone during osteotomy. Aim of the Study: To evaluate the effectiveness of trephine osteotomy during sinus floor augmentation using the autogenous bone resulting from implant trephine drills with a lateral sinus lifting approach. Material and Method: In this clinical study, 12 Patients were included and have been subjected to lateral sinus lifting using trephine osteotomy. A bone graft used in sinus floor augmentation has been prepared using autogenous bone resulting from implant site preparation in addition to β-tricalcium phosphate. Outcome measurements consisted of both clinical and radiographical evaluation. Results: After 6 months, the difference between the primary stability and implant stability was statistically significant as p-value ≤ 0.05. After 6 months, The mean bone density and the mean vertical bone height were increased by 984.7 ± 276.2 mm and 11.71 ± 0.72 mm respectively. Conclusion: Trephine osteotomy technique in both lateral approach of sinus lifting and implant site preparation allows preservation of autogenous bone. Moreover, the trephine osteotomy technique in lateral approach of sinus lifting eliminates the use of an absorbable membrane. However, this technique requires proper case selection and is considered sensitive. | ||
