Summary
Vertical alveolar ridge augmentation using mandibular bone cores effectively restored bone defects. This technique enabled successful dental implant placement and improved aesthetics in the anterior maxilla.
Area of Science:
- Dentistry
- Oral and Maxillofacial Surgery
- Regenerative Medicine
Background:
- Vertical alveolar ridge defects compromise dental implant placement and aesthetic outcomes.
- Restoring resorbed alveolar ridges is crucial for successful implant dentistry.
- The anterior maxilla presents unique challenges for bone augmentation procedures.
Observation:
- A patient with localized vertical bone defects (7mm right, 6mm left) around maxillary lateral incisors was treated.
- Two bone cores were harvested from the mandibular symphysis using a trephine.
- These bone cores were used for vertical ridge augmentation in the anterior maxilla.
Findings:
- Vertical augmentation of 5mm (right) and 4mm (left) was achieved after 5 months.
- The ridge width also increased, facilitating favorable implant positioning.
- Two implants were successfully placed, restored, and followed for 1 year post-loading.
Implications:
- This symphyseal bone core technique is a viable option for vertical alveolar ridge augmentation.
- It offers a predictable method for restoring bone volume prior to dental implant placement.
- The procedure enhances functional and aesthetic results in complex maxillary reconstructions.
