MK II - THE SELF-TAPPING BRANEMARK IMPLANT - 5-YEAR RESULTS OF A PROSPECTIVE 3-CENTER STUDY

The 5-year result of a prospective 3-center study is presented, compri sing 103 patients with 288 Mk II self-tapping and 275 standard implant s of the Branemark System((R)). Out of 363 mandibular and 200 maxillar y fixtures, one Mk II was lost of the lower jaw and 13 of each implant type failed in maxillae during the study period. Cumulative prosthesi s stability was 97%. Five patients accounted for more than 85% of the fixture losses. Marginal bone resorption was similar for both implant designs. A part from the implant failures and one patient exhibiting d isturbed nerve sensation of the mental nerve, no major complications w ere encountered. Overall, this study revealed equal cumulative success rates for standard and Mk II implants after 5 years of observation. M andibular implants exhibited greater success rates (100%) for both tes ted implant types compared to maxillary implants (87%).
