Simultaneous implant placement with ridge augmentation using an autogenous bone ring transplant

Area of Science:

• Oral and Maxillofacial Surgery
• Periodontology
• Dental Implantology

Background:

• Severely defective bone sockets often preclude immediate dental implant placement.
• Bone grafting is typically required as an initial surgical intervention for socket augmentation.

Purpose of the Study:

• To evaluate the consolidation of autogenous chin bone rings used for augmenting defective sockets.
• To assess the clinical application of these bone rings with simultaneous implant placement in a one-stage procedure.

Main Methods:

• Ten patients with 12 defective sockets underwent augmentation using autogenous chin bone rings.
• Bone rings were harvested from the chin and fitted into prepared sockets, followed by implant placement through the ring and into the apical bone.
• Clinical and radiographic examinations were performed immediately and at 6 months postoperatively, with statistical evaluation of crestal bone changes.

Main Results:

• All grafted sockets exhibited successful bone healing with no significant crestal bone resorption or infection.
• One bone ring showed dehiscence, which resolved during the follow-up period.
• All placed dental implants demonstrated radiographic evidence of osseointegration.

Conclusions:

• Autogenous chin bone ring augmentation is a reliable method for managing severely defective bone sockets.
• This technique facilitates a one-stage surgical procedure for dental implant placement in augmented sites.
• The study supports the use of chin bone rings as a viable alternative for socket reconstruction.
