Stress\u2010related factors, such as implant size, have been associated with changes in crestal bone levels on dental implants. The purpose of this study is to evaluate the effect of an implant size, specifically 5 mm wide \u00d7 8 mm long (5 \u00d7 8), on peri\u2010implant bone levels.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> A retrospective cohort study was conducted. The cohort was composed of patients who had \u22651 plateau root\u2013form implant. Descriptive statistics, univariate and multivariate mixed\u2010effects regression models, adjusted for multiple implants in the same patient were used to evaluate the correlation between 5 \u00d7 8 implants and other clinically relevant factors on crestal bone levels after insertion of single\u2010tooth replacements.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> The cohort was composed of 81 individuals who received 326 implants. The average change in crestal bone levels (AvBL) for 5 \u00d7 8 maxillary and mandibular implants after 5.9 years of follow\u2010up were \u22120.36 and \u22120.04 mm, respectively. In contrast, AvBL for mandibular implants not measuring 5 \u00d7 8 was \u22120.51 mm. Of several different local and systemic factors evaluated, including 10 different implant sizes, 5 \u00d7 8 mandibular implants were found to be significantly less likely to lose bone when compared with mandibular implants not measuring 5 \u00d7 8 (<jats:italic>P<\/jats:italic> = 0.047).<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold> Implants measuring 5 \u00d7 8 demonstrated statistically significantly less peri\u2010implant bone loss in the posterior mandible. This finding indicated that a specific implant size may be involved in mandibular bone preservation. However, prospective multicenter clinical trials are needed to validate these findings.<\/jats:p>","DOI":"10.1902\/jop.2012.110299","type":"journal-article","created":{"date-parts":[[2012,2,6]],"date-time":"2012-02-06T11:38:23Z","timestamp":1328528303000},"page":"1235-1244","source":"Crossref","is-referenced-by-count":13,"title":["The Effect of Implant Size 5 \u00d7 8 mm on Crestal Bone Levels Around Single\u2010Tooth Implants"],"prefix":"10.1002","volume":"83","author":[{"given":"Rainier A.","family":"Urdaneta","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joseph","family":"Leary","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William","family":"Lubelski","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kimberly M.","family":"Emanuel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sung\u2010Kiang","family":"Chuang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,10]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0022-3913(89)90081-4"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2007.060139"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1708-8208.2009.00182.x"},{"key":"e_1_2_7_5_1","first-page":"318","article-title":"Single\u2010tooth replacement by osseointegrated Astra Tech dental implants: A 2\u2010year report","volume":"10","author":"Karlsson U","year":"1997","journal-title":"Int J Prosthodont"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2008.01626.x"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2006.01306.x"},{"key":"e_1_2_7_8_1","first-page":"253","article-title":"Changes in crestal bone levels for immediately loaded implants","volume":"21","author":"Yoo RH","year":"2006","journal-title":"Int J Oral Maxillofac Implants"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.2006.01008.x"},{"key":"e_1_2_7_10_1","first-page":"1063","article-title":"Factors associated with crestal bone gain on single\u2010tooth locking\u2010taper implants: The effect of nonsteroidal anti\u2010inflammatory drugs","volume":"26","author":"Urdaneta RA","year":"2011","journal-title":"Int J Oral Maxillofac Implants"},{"key":"e_1_2_7_11_1","first-page":"208","article-title":"Early experience with Wide\u2010Platform Mk II implants.
