The aim of this study was the clinical and radiographic evaluation of hollow cylinder implants that were inserted during the time period of 1978\u20131987 in partially and completely edentulous patients to support overdentures, fixed partial prostheses and single crowns. Altogether, 71 patients with a total of 132 hollow cylinder ITI\u2010implants still <jats:italic>in situ<\/jats:italic> had been followed regularly during the entire observation period of 11.4 to 19.7 years (mean 14.1). Thirteen implants had to be removed before an observation period of 10 years was completed, 4 additional implants were lost after being in function for over 10 years and two further implants were considered to be failures at the time of the examination. Thus 91.4% of the implants were still <jats:italic>in situ<\/jats:italic> after 10 years and the survival rate for a mean observation period of 14.1 years was 84.6%. Periimplant parameters were used to assess the clinical conditions of the implants. On the radiographs, horizontal bone loss or angular defects could be detected on 40% of all implants if compared to the base\u2010line situation. The probing depths around these implants were significantly increased compared to implants with an unchanged bone level, however the mean probing depths did not exceed 3.5 mm and 2.8 mm respectively. From this clinical evaluation one may conclude that with the early generation of hollow cylinder ITI\u2010implants favorable long\u2010term results were achieved.<\/jats:p>","DOI":"10.1034\/j.1600-0501.2001.012003252.x","type":"journal-article","created":{"date-parts":[[2003,3,11]],"date-time":"2003-03-11T12:37:35Z","timestamp":1047386255000},"page":"252-259","source":"Crossref","is-referenced-by-count":40,"title":["Long\u2010term evaluation of non\u2010submerged hollow cylinder implants"],"prefix":"10.1111","volume":"12","author":[{"given":"Regina","family":"Merickse\u2010Stern","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dominik","family":"Aerni","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alfred H.","family":"Geering","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Buser","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2002,1,19]]},"reference":[{"key":"e_1_2_6_2_1","first-page":"749","article-title":"Hard and soft tissue reactions to ITI screw implants: 3\u2010year longitudinal results of a prospective study.","volume":"12","author":"Behneke A.","year":"1997","journal-title":"International Journal of Oral & Maxillofacial Implants"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0501.1998.090402.x"},{"issue":"16","key":"e_1_2_6_4_1","first-page":"1","article-title":"Osseointegrated implants in the treatment of the edentulous jaw.
