Summary
This study demonstrates a novel technique using a demineralized dentin plate from an extracted tooth for guided bone regeneration (GBR). This method successfully augmented a posterior jaw ridge for dental implant placement, offering an alternative to traditional bone grafts.
Area of Science:
- Dental Regenerative Medicine
- Biomaterials Science
- Oral Surgery
Background:
- Horizontal ridge deficiency presents a challenge for dental implant placement.
- Guided bone regeneration (GBR) is a common surgical procedure to augment bone volume.
- Autogenous bone grafts are typically used but have limitations.
Observation:
- A partially demineralized dentin plate was fabricated from an extracted second molar.
- The dentin plate was used for horizontal ridge augmentation in a patient with posterior ridge deficiency.
- The augmentation site was further enhanced with cortico-cancellous allograft and a collagen membrane.
Findings:
- Post-operative cone-beam computed tomography (CBCT) at 6 months showed sufficient ridge width for implant placement.
- The dentin plate integrated with the alveolar ridge, as evidenced by CBCT.
- A dental implant was successfully placed in the augmented site.
Implications:
- Partially demineralized dentin plates offer a viable alternative to autogenous bone grafts for GBR.
- This technique provides a potential solution for utilizing extracted teeth in regenerative dentistry.
- Meticulous graft preparation and fixation are crucial for successful outcomes in GBR procedures.
