This case report details the successful reconstruction of a jaw deformity and alveolar bone defect using a custom titanium mesh and autogenous bone graft. Three-dimensional simulation guided the surgical bone augmentation and subsequent dental implant placement for improved function and aesthetics.
Area of Science:
- Oral and Maxillofacial Surgery
- Regenerative Medicine
- Biomaterials Engineering
Background:
- Alveolar bone defects necessitate bone augmentation for functional and esthetic restoration.
- Causes include trauma, tumor resection, congenital issues, and periodontitis.
- Maxillary anterior defects pose significant reconstructive challenges.
Observation:
- A 26-year-old male presented with a jaw deformity and alveolar bone deficiency in the maxillary anterior region due to childhood trauma.
- Preoperative diagnosis confirmed the extent of the bone and tooth deficiency.
Findings:
- A combined surgical approach involved sagittal split ramus osteotomy and maxillary anterior bone augmentation.
- A custom-made titanium mesh combined with autogenous iliac particulate cancellous bone and marrow was utilized.
- Three-dimensional simulation guided the precise placement of the bone graft.
- Dental implants were successfully placed in the augmented bone 4 months post-surgery, followed by prosthetic rehabilitation.
Implications:
- This case highlights the efficacy of 3D simulation in planning complex alveolar bone reconstructions.
- The described technique offers a viable solution for restoring both function and esthetics in patients with significant jaw deformities.
- This approach may be applicable to a range of alveolar bone defect etiologies.
