All implants were placed in healed sites and had to be inserted with a torque &gt;25 Ncm. The implants in the immediate\u2010restoration group were fitted with a non\u2010occluding temporary crown on the day of surgery. Both groups received a full occluding final crown 6 months after surgery. Mean marginal bone loss, probing depth, and bleeding on probing were assessed at 6\u2010, 12\u2010, 24\u2010, and 36\u2010month follow\u2010up examinations by a masked examiner.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> Sixty 3.0\u2010mm\u2010diameter implants were placed between July 2003 and February 2006; 27 (45.0%) were in men, and 33 (55.0%) were in women. All implants osseointegrated and were clinically stable at the 6\u2010month follow\u2010up. No statistically significant differences were observed for bleeding or plaque index. No implant fractures occurred. At the 36\u2010month follow\u2010up, the accumulated mean marginal bone loss and probing depth were 0.85 \u00b1 0.71 mm and 1.91 \u00b1 0.59 mm, respectively, for the immediate\u2010loading group (n = 30) and 0.75 \u00b1 0.63 mm and 2.27 \u00b1 0.81 mm, respectively, for the one\u2010stage group (n = 30). There was no statistically significant difference (<jats:italic>P<\/jats:italic> &gt;0.05) for the tested outcome measures between the two procedures.<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold> In the rehabilitation of a single missing lateral maxillary incisor, no statistically significant difference was assessed between immediately and one\u2010stage restored small\u2010diameter implants with regard to implant survival, mean marginal bone loss, and probing depth. Three\u2010millimeter\u2010diameter implants proved to be a predictable treatment option in our test and control groups if a strict clinical protocol was followed.<\/jats:p>","DOI":"10.1902\/jop.2009.090153","type":"journal-article","created":{"date-parts":[[2009,9,1]],"date-time":"2009-09-01T08:49:24Z","timestamp":1251794964000},"page":"1393-1398","source":"Crossref","is-referenced-by-count":62,"title":["Immediate Versus One\u2010Stage Restoration of Small\u2010Diameter Implants for a Single Missing Maxillary Lateral Incisor: A 3\u2010Year Randomized Clinical Trial"],"prefix":"10.1002","volume":"80","author":[{"given":"Marco","family":"Degidi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diego","family":"Nardi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adriano","family":"Piattelli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2009,9]]},"reference":[{"key":"e_1_2_7_2_1","first-page":"8","article-title":"Single tooth replacement with a one\u2010stage implant: Case reports","volume":"23","author":"Meredith GM","year":"1992","journal-title":"Hawaii Dent J"},{"key":"e_1_2_7_3_1","first-page":"184","article-title":"Optimal esthetics in single\u2010tooth replacement with the Re\u2010Implant system: A case report","volume":"12","author":"Heydecke G","year":"1999","journal-title":"Int J Prosthodont"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0757.1998.tb00128.x"},{"issue":"9","key":"e_1_2_7_5_1","first-page":"4","article-title":"A modular approach to dental implant therapy: The appropriate selection of one\u2010 and two\u2010stage surgeries","volume":"23","author":"Cooper LF","year":"2002","journal-title":"Compend Contin Educ Dent"},{"key":"e_1_2_7_6_1","first-page":"44","article-title":"Use of a one\u2010stage narrow\u2010diameter implant to replace incisors","volume":"88","author":"Wojcik MS","year":"2006","journal-title":"J Mich Dent Assoc"},{"key":"e_1_2_7_7_1","first-page":"436","article-title":"Bone augmentation at single\u2010tooth implants using mandibular grafts: A one\u2010stage surgical procedure","volume":"15","author":"Friberg B","year":"1995","journal-title":"Int J Periodontics Restorative Dent"},{"key":"e_1_2_7_8_1","first-page":"1107","article-title":"Single\u2010tooth replacement in the aesthetic zone with immediate provisionalization: Fourteen consecutive case reports","volume":"10","author":"W\u00f6hrle PS","year":"1998","journal-title":"Pract Periodontics Aesthet Dent"},{"key":"e_1_2_7_9_1","first-page":"31","article-title":"Immediate placement and provisionalization of maxillary anterior single implants: 1\u2010year prospective study","volume":"18","author":"Kan JY","year":"2003","journal-title":"Int J Oral Maxillofac Implants"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1708-8208.2007.00029.x"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1708-8240.2000.tb00221.x"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1708-8208.2007.00038.x"},{"key":"e_1_2_7_13_1","first-page":"769","article-title":"Correlation between placement torque and survival of single\u2010tooth implants","volume":"20","author":"Ottoni JM","year":"2005","journal-title":"Int J Oral Maxillofac Implants"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1708-8240.2005.tb00138.x"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0501.2003.00950.x"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joms.2005.10.021"},{"key":"e_1_2_7_17_1","first-page":"449","article-title":"Narrow\u2010diameter implants: A restorative option for limited interdental space","volume":"27","author":"Froum SJ","year":"2007","journal-title":"Int J Periodontics Restorative Dent"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2007.01410.x"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1708-8208.2007.00054.x"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2007.01346.x"},{"key":"e_1_2_7_21_1","first-page":"450","article-title":"Osseointegrated implants for single\u2010tooth replacement: A prospective 5\u2010year multicenter study","volume":"11","author":"Henry PJ","year":"1996","journal-title":"Int J Oral Maxillofac Implants"},{"key":"e_1_2_7_22_1","first-page":"115","article-title":"Frossard WM, Ferreira HM, de Menezes Filho LM, Touati B.
