Anterior mandibular dentoalveolar advancement utilizing lyophilized bone
International Journal of Oral Surgery
|August 1, 1979
Summary
This study addresses complex Class II malocclusions by proposing anterior mandibular dentoalveolar advancement. Lyophilized bone is recommended to prevent complications associated with autologous grafts.
Area of Science:
- Orthodontics and Maxillofacial Surgery
- Dental Bone Grafting Techniques
Background:
- Class II malocclusions with specific facial profiles and mandibular anomalies pose diagnostic and treatment challenges.
- Existing treatment modalities may not adequately address complex cases involving interarch width discrepancies and exaggerated mandibular curve of Spee.
Observation:
- Patients present with low angle Class II malocclusions, prominent nasal and chin features, and discrepancies in arch width.
- An exaggerated curve of Spee in the mandible complicates treatment planning.
Findings:
- Anterior mandibular dentoalveolar advancement is proposed as a viable treatment option for these complex cases.
- The use of lyophilized, homologous bone is recommended for bone grafting to mitigate risks of root resorption and ankylosis associated with autologous bone.
- A modified surgical incision technique is presented to ensure watertight wound closure.
Implications:
- This approach offers a potential solution for challenging Class II malocclusions, improving both aesthetics and function.
- The use of allogeneic bone may enhance predictability and reduce surgical morbidity.
- Improved surgical techniques can lead to better patient outcomes and recovery.
