Abstract
This study was conducted on twelve patients selected from the outpatient clinic of the oral and maxillofacial surgery department, faculty of dentistry, Minia University. Patients were of both genders with ages ranged between 45-60 years old. They were free of any systemic disease that could affect the final results were excluded from the study. All the selected mandibular ridges were narrow and have adequate space for implant insertion.
The aim of this research was to evaluate the osseointegration of implants placed in mandibular narrow alveolar ridge after ridge splitting osteotomy with and without bone grafting Patients were divided into two groups, group (1) included patients who received implants after ridge splitting and autogenous bone grafting in the split area, where group (2) included patients who received implants after ridge splitting without bone grafting in the split area. Preoperative general assessment and preparation of the patients in termsof history, physical examination and study models were taken forall cases. Clinically the implants were assessed for any mobilty, pain or inflamation. Also, radiographic evaluation was done to show marginal bone loss and bone density changes around the implants.
The clinical and radiographic follow up period that extended up to one year showed that implants in both groups had successful osseointegration with implants in group (1) had better osseointegration than group (2) in terms of marginal bone loss and bone density.
Conclusion
•Ridge splitting osteotomy technique is a promising procedure for ridge expansion especially in narrowing mandibular ridge.
•The osteotomy methods compared more favorably than ridge augmentation or distraction as they offer better expansion and primary stability of the implant
•The implant success is very predictable especially when bone osteotomy is conservative and the blood suply is preserved.
•Bone grafting proved more valuable for improving osseointegration of implants placed in the splitted mandibular ridges.
