Abstract

Objective: To Compare and contrast different intraoral autogenous grafts for 3D reconstruction of atrophic anterior maxillae, to receive dental implants.

Patients & Methods: Twelve patients suffering from anterior maxillary bone resorption and in need for bone augmentation to be able to place dental implants were included in this study. Autogenous bone grafts were harvested from either the symphyseal region (Group A) or the retromolar region (Group B). Assessments were performed using CBCT both pre- and post-operatively; as well as, clinically on delayed implant placement.

Results: Both groups showed significant bone formation at 4 months postoperatively, and implants were placed with adequate initial stability. Group A, showed significantly higher insertion torque mainly occlusal and midway upon placement than Group B. All cases had uneventful fixed prosthetic loading of implants.

Conclusion: Both symphyseal and retromolar intraoral donor graft sites provide successful graft material for anterior maxillary 3D reconstruction, however, the symphyseal grafts despite providing better initial stability for implants, yet, were less perceivable by the patients regarding postoperative pain and oedema; and provided no significant difference regarding successful loading of dental implants with fixed prosthetics.
