DESEMPENHO CLÍNICO DOS IMPLANTES CURTOS: UM ESTUDO RETROSPECTIVO DE SEIS ANOS Clinical performance of short implants: a six-year retrospective study.

Implants and implant prosthetic success rates and longevity are higher than natural teeth-supported prostheses. Due to limiting anatomical factors, implants placed in the posterior regions are often shorter than those placed in the anterior regions. The aim of this study was to retrospectively evaluate the clinical performance of short implants in a six year period. This study evaluated 348 short implants inserted in anterior and posterior regions in both jaws of 153 patients. Out of 348 inserted implants, 220 were of 9 mm and 128 of 10 mm of length, with diameters of 3.5 mm, 4.0 mm and 5 mm. Forty-five implants were placed in sites treated with the principle of guided bone regeneration. Anterior and posterior regions received 45 and 303 implants, respectively. In 19 cases the immediate installation was performed. All implants were prosthetically rehabilitated with single or multiple prostheses. Success rate was 96% (334 implants). It can be concluded that short-length implants may be used to support fixed restorations in the rehabilitation of missing teeth, with the similar success rate and longevity of long implants.
