Computed tomography and computer-aided design for locating available palatal bone for grafting: two case reports

Area of Science:

• Oral and Maxillofacial Surgery
• Regenerative Medicine
• Biomaterials

Background:

• Autologous bone grafting is the standard for oral and maxillofacial rehabilitation.
• Identifying optimal donor sites is crucial for successful bone reconstruction.
• The palate's potential as a donor site requires further investigation.

Observation:

• A novel surgical technique utilizing computer-aided design (CAD) for palatal bone grafting was developed.
• Computed tomography (CT) and Simplant software were employed for detailed analysis of the palatal donor site.
• Corticocancellous bone blocks were harvested from the palate using a trephine, with no adverse events like swelling or hematomas reported.

Findings:

• Simplant software effectively mapped bone quantity and quality within the palatal region.
• The evaluated palatal bone met the criteria for reconstructive purposes.
• The technique facilitated precise preoperative planning for dental implant placement.

Implications:

• The palate presents a promising and accessible donor site for oral and maxillofacial bone grafting.
• CAD and CT imaging significantly improve the predictability and safety of palatal bone harvesting.
• This approach can enhance outcomes for patients requiring dental implants and maxillofacial reconstruction.
