This study shows that combining iliac bone flaps with immediate implant-based dentures is a safe and effective one-stage mandibular reconstruction technique. The procedure offers high implant survival and minimal complications for patients with benign tumors.
Area of Science:
- Oral and Maxillofacial Surgery
- Reconstructive Surgery
- Dental Implantology
Context:
- Mandibular defects often require complex reconstruction.
- One-stage reconstruction aims to improve patient outcomes and reduce treatment time.
- Iliac bone flaps offer a viable source for mandibular reconstruction.
Purpose:
- To evaluate the clinical outcomes of a one-stage mandibular reconstruction using iliac bone flaps and immediate implant-based dentures.
- To define indications for this combined technique.
- To assess surgical planning accuracy and long-term success.
Summary:
- Ten patients with benign tumors underwent one-stage mandibular reconstruction with iliac bone flaps and immediate implant-based dentures.
- Virtual surgical planning (VSP) accuracy was high, with average overall deviation of 1.14 mm.
- Implant survival was 100% during follow-up (median 23.5 months), with a 4-year cumulative survival rate of 97.37% and minimal bone resorption (0.94 mm).
Impact:
- This technique demonstrates promising clinical outcomes for mandibular reconstruction.
- It offers a safe and reliable option with high implant survival and low complication rates.
- Further research with larger cohorts and longer follow-up is warranted to confirm long-term efficacy.
