Title: The synergy in functional load of short dental implants and fiber reinforced substructures in free fibula transplants
Abstract:
This multi-center retrospective study evaluated the survival and success of short and extra short locking-taper dental implants placed in both maxillary and mandibular iliac crest-, fibula-, and scapula grafts.
A total of 49 patients were treated across five study sites and received 186 implants in iliac crest-, fibula-, and scapula grafted sites. Out of those patients, 34 received prostheses. Kaplan-Meier survival analysis was used to assess the survival and success rates of both implants and prostheses. Multivariate Cox regression was used to correlated study covariates to implant survival outcomes.
The overall thirteen-year implant survival rate was 86.2% (95% confidence interval: 81.6-94.0%), while the implant success rate was 78.9% (95% confidence interval: 62.3-87.7%.) The prosthesis survival rate at 12.8 years after prosthesis insertion was 89.4% (95% confidence interval: 62.5-95.4%); while the prosthetic success rate was 81.2% (95% confidence interval: 62.0-93.7%.) Implant placement in the mandible, patient age, systemic conditions, and irradiation after implant surgery were correlated with reduced implant survival; while maxillary implant placement, antiresorptive drug use, and tooth loss due to trauma were correlated with improved survival.
Short and extra short locking-taper dental implants provide a viable solution for the restoration of dentition in patients receiving iliac crest-, fibula-, and scapula grafts for maxillary or mandibular reconstruction.
