Success Rate of Immediate Functional Loading Implants over a Period of 5 Years - A Retrospective Study.

Introduction: Immediate functional loading implants have picked up pace in the era of implant dentistry not only in terms of offering fast, secure and definitive treatment, but also in the realm of comfort, phonetics, aesthetic, and masticatory functions. The aim was to evaluate the success rate of strategic implant-supported prosthesis over five years.

Materials and methods: A total of 5108 implants were placed in accordance with the need of rehabilitation of individual full jaw and segment. All ceramic, metal-fused ceramic and metal acrylic prostheses were given as per the requirement. The evaluation of criteria includes fracture or decementation of the prostheses. The statistical analysis was done with the Chi-square test for the success rate of implant and failure of the prostheses.

Results: A total of 154 implants failed, 80 in the maxilla and 74 in the mandible. Five metal acrylic bridges were damaged out of 170. As for metal ceramic bridges, 6 out of 206 full arches and 11 segments out of 215 were damaged.

Discussion: The ceramic prostheses have more efficiently met the success criteria followed by the metal acrylic prostheses. Since all-ceramic prostheses were only given into the anterior region, no failures were seen in those prostheses. The immediate functional loading implants have a 97% success rate even though there is shortcoming of prosthesis.
