This study evaluated maxillary sinus reconstruction using iliac bone grafts and titanium implants. The procedure achieved a high implant survival rate (80.9%) and successful fixed prosthesis rehabilitation (100%).

Area of Science:

  • Oral and Maxillofacial Surgery
  • Dental Implantology
  • Bone Grafting Techniques

Background:

  • Maxillary sinus reconstruction is crucial for dental implant placement in atrophic jaws.
  • Iliac corticocancellous bone blocks offer a viable grafting material for sinus floor augmentation.
  • Two-stage reconstruction allows for graft consolidation before implant placement.

Purpose of the Study:

  • To assess the outcomes of a two-stage maxillary sinus reconstruction protocol.
  • To evaluate titanium implant survival and prosthetic rehabilitation following iliac bone grafting to the sinus floor.
  • To determine the success rates of implants placed in grafted sinus bone versus adjacent grafted alveolar bone.

Main Methods:

  • Prospective evaluation of 50 consecutive patients undergoing two-stage maxillary sinus reconstruction.

  • Placement of 314 Brånemark titanium implants into iliac corticocancellous bone blocks grafted to the sinus floor and adjacent alveolar bone.
  • Follow-up ranging from 9 to 48 months post-implant placement, with implant integration and prosthetic success recorded.

    • Main Results:

    • Implant integration rates were 84% in grafted sinuses and 75% in the anterior alveolar graft.
    • Overall implant survival rate was 80.9%, with a 100% survival rate for fixed prostheses.
    • Twelve percent of patients required secondary implant placement due to strategic implant loss; 76% received fixed prostheses.

    Conclusions:

    • Two-stage maxillary sinus reconstruction with iliac bone blocks and titanium implants yields favorable implant survival and prosthetic success rates.
    • This technique effectively restores the maxillary bone for dental implant rehabilitation.
    • The results compare favorably with existing literature on sinus augmentation and implantology.
