title: Mk II: the self-tapping Brånemark implant: 5-year results of a prospective 3-center study.
abstract: The 5-year result of a prospective 3-center study is presented, comprising 103 patients with 288 Mk II self-tapping and 275 standard implants of the Brånemark System. Out of 363 mandibular and 200 maxillary fixtures, one Mk II was lost of the lower jaw and 13 of each implant type failed in maxillae during the study period. Cumulative prosthesis stability was 97%. Five patients accounted for more than 85% of the fixture losses. Marginal bone resorption was similar for both implant designs. Apart from the implant failures and one patient exhibiting disturbed nerve sensation of the mental nerve, no major complications were encountered. Overall, this study revealed equal cumulative success rates for standard and Mk II implants after 5 years of observation. Mandibular implants exhibited greater success rates (100%) for both tested implant types compared to maxillary implants (87%).
