Summary
Growth factor bioavailability-enhanced allograft (GFBA) shows promise as an alternative to autogenous bone grafting for alveolar ridge augmentation. This study demonstrated successful implant placement and osseointegration in moderate anterior maxilla defects using GFBA.
Area of Science:
- Oral and Maxillofacial Surgery
- Regenerative Dentistry
- Dental Implantology
Background:
- Alveolar ridge deficiencies in the anterior maxilla can hinder dental implant placement.
- Autogenous bone grafting is the standard, but alternatives are sought.
- Growth factor bioavailability-enhanced allograft (GFBA) offers a potential solution.
Purpose of the Study:
- To evaluate the efficacy of GFBA in alveolar ridge augmentation for anterior maxilla implant rehabilitation.
- To compare GFBA with autogenous bone grafting in a clinical case.
Main Methods:
- A patient with a missing tooth and a non-restorable tooth in the anterior maxilla underwent ridge augmentation.
- Site No. 8 was augmented with an autogenous ramus block graft.
- Site No. 7 involved extraction and socket grafting with GFBA.
- Cone-beam computed tomography was used for assessment.
Main Results:
- Both GFBA and autogenous grafts achieved successful ridge augmentation at 11 months.
- GFBA demonstrated homogeneous trabecular patterns and advanced integration.
- Autogenous grafts showed ongoing remodeling and integration.
- Implants were successfully placed and osseointegrated at both sites with stable bone levels.
Conclusions:
- GFBA can be a viable alternative to autogenous bone grafting for moderate alveolar ridge defects.
- Successful implant outcomes were achieved with GFBA in the anterior maxilla.
