Summary
Alveolar ridge defects after tooth loss hinder dental implants. Segmental osteotomy with bone grafting successfully corrected vertical bone loss in the posterior maxilla, enabling implant placement.
Area of Science:
- Dentistry
- Oral Surgery
- Regenerative Medicine
Background:
- Tooth loss triggers alveolar bone resorption, creating defects that compromise dental implant feasibility.
- Vertical and horizontal bone defects in the alveolar ridge present significant challenges for restorative dental surgery.
- Segmental osteotomy with interpositional bone grafting is a recognized surgical approach for alveolar bone reconstruction.
Observation:
- This case report details the treatment of a patient with vertical dimension deficiency in the posterior maxillary region.
- The patient underwent segmental osteotomy combined with interpositional bone grafting to address the bone defect.
- The surgical procedure aimed to restore bone height for subsequent dental implant placement.
Findings:
- The segmental osteotomy and bone grafting technique successfully corrected the vertical bone deficiency.
- Four months post-surgery, the grafted bone showed sufficient regeneration and stability.
- Three dental implants were successfully placed in the reconstructed posterior maxillary region, aligning with the initial reverse planning.
Implications:
- This technique offers a viable solution for complex alveolar bone defects, expanding treatment options for dental implant patients.
- Successful bone reconstruction using segmental osteotomy and grafting facilitates predictable implant placement and long-term restoration.
- The findings support the use of this surgical method in managing vertical bone loss for improved functional and aesthetic outcomes in implant dentistry.
