Abstract
Objective: Loading of titanium craniofacial implants is dependent upon osseointegration, the bonding of titanium oxide and bone. The purpose of this study seeks to determine the safety of early loading of the Baha BI-300 implant system (Cochlear Limited, Englewood, Colorado), which has been modified with novel surface texture and geometric design.
Method: This prospective multi-institutional study follows implant stability as determined by clinical evaluation and resonance frequency analysis (RFA) at implantation, 1, 3, 6, 12, and 24 weeks postopative, in 20 patients who underwent single-stage implantation and exteriorization of the BI-300. The processor was loaded at 3 weeks postoperative.
Results: Implant stability and the incidence of implant loss was compared with patients loaded at 6 weeks and the traditional 12 weeks postoperative. Our preliminary results confirm implant stability at 3 weeks postoperative. No increase in implant loss or postoperative complications were encountered as a result of the early loading.
Conclusion: Three-week loading of the BI-300 implant did not result in any failure of osseointegration. Earlier activation of the external processor with earlier hearing rehabilitation resulted in improved patient satisfaction.
