Replacement of mandibular posterior teeth with implants in a postmandibular resection case: a case report

Area of Science:

• Oral and Maxillofacial Surgery
• Prosthodontics
• Biomaterials

Background:

• Ameloblastoma resection often results in significant mandibular defects.
• Effective bone regeneration and functional restoration are critical post-resection challenges.
• Patient preference for fixed prostheses influences treatment planning.

Observation:

• A healing obturator was utilized to facilitate bone formation in a large mandibular defect post-segmental resection.
• Significant bone fill, reaching the ridge crest, was observed after 3 months of obturator use.
• The patient opted for a fixed dental solution over a removable one.

Findings:

• The healing obturator successfully promoted substantial bone regeneration within the mandibular defect.
• Implant-supported fixed prostheses provide a viable solution for restoring dentition after extensive mandibular resection.
• Progressive loading of the implant-supported prosthesis was the chosen rehabilitation strategy.

Implications:

• Healing obturators can be effective in reconstructing large mandibular defects, aiding bone regeneration.
• Implant-supported fixed prostheses offer a stable and functional outcome for patients with post-surgical mandibular defects.
• This approach highlights the successful integration of reconstructive and prosthetic phases in managing ameloblastoma treatment sequelae.
