Negotiating the severely resorbed extraction site: a clinical case report with histologic sample

Area of Science:

• Dental Implantology
• Periodontal Regeneration
• Oral Surgery

Background:

• Treating infected sockets with severe facial defects poses challenges for dental professionals.
• Implant-supported restorations and fixed partial dentures are potential solutions with varying outcomes.

Observation:

• A multi-stage regenerative approach was used for an implant-supported single crown after maxillary central incisor extraction.
• Initial grafting with biphasic calcium sulfate (BCS) showed partial regeneration, exposing implant threads.
• Subsequent augmentation with freeze-dried bone allograft (FDBA) and a collagen membrane addressed the defect.

Findings:

• Histology confirmed complete resorption of grafted material and new woven bone formation.
• Clinical evaluation showed complete defect regeneration and alveolar ridge augmentation within 4 months.
• The regenerative approach enabled successful implant placement and restoration.

Implications:

• This regenerative strategy offers a viable option for complex alveolar ridge defects.
• Clinicians should weigh the benefits and drawbacks of this approach against conservative alternatives.
• Successful bone regeneration is crucial for predictable dental implant outcomes in compromised sites.
