Immediate Placement of Dental Implant with Ridge Augmentation Using Autogenous Bone Ring Transplant

Abstract

Aim: This study was designed to evaluate autogenous chin bone ring consolidation after the augmentation of severely defective sockets and the clinical application of these rings in the premolar–molar region with simultaneous implant placement in a one-stage procedure. Subjects and Methods: Ten patients were selected from those attending the outpatient clinic of the Department of Oral and Maxillofacial Surgery, Faculty of Dental Medicine, Boys, Cairo, Al Azhar University. All selected patients had fresh defective extraction sockets in the mandibular premolar molar region with severely compromised buccal bone. Clinical examination was made to all patients as: Quality, quantity of the bone, mucosa, contour of the underlying bone. Preoperative cone beam CT was taken for every patient to determine alveolar bone height& width. The change in the implant stability and bone density was measured using cone beam computerized tomography (CBCT) immediately, and after 6 months of healing. All readings were recorded and evaluated statistically. Results: The difference between crestal bone height immediate and six months postoperatively was statistically significant in buccal and lingual surface (p value = 0.001), (p value =0.000) respectively. While was not statistically significant in mesial and distal surface (p value = 0.068), (p value =0.960) respectively. Conclusion: The autogenous chin bone ring augmentation technique was found to be a reliable alternative method for the management of severely defective sockets.
