Summary
Particulate hydroxyapatite (HA) combined with a resorbable collagen membrane effectively regenerated bone in a challenging alveolar ridge deficiency case. This approach offers a viable alternative to traditional grafting methods for dental implant preparation.
Area of Science:
- Dental Surgery
- Regenerative Medicine
- Biomaterials
Background:
- Ridge augmentation is a complex surgical procedure to address bony deficiencies.
- Non-degradable membranes pose risks like infection and require a second surgery.
- Resorbable membranes and bone graft materials are used to overcome these limitations.
Purpose of the Study:
- To evaluate the efficacy of particulate hydroxyapatite (HA) and a collagen membrane for localized ridge augmentation.
- To present a case study of treating a missing maxillary incisor with ridge deficiency.
Main Methods:
- Localized ridge augmentation using particulate hydroxyapatite bone graft material.
- Application of a resorbable collagen membrane to maintain space and support graft material.
Main Results:
- Significant vertical bone fill was observed six months post-surgery.
- Radiographic evidence confirmed successful bone regeneration.
Conclusions:
- Hydroxyapatite in conjunction with a resorbable collagen membrane is a promising alternative for treating compromised alveolar ridge deficiencies.
- This combination avoids donor site morbidity associated with autogenous grafts and the drawbacks of non-resorbable membranes.
