Furthermore, the influence of an augmentation procedure 3\u00a0months before implant placement and the type of restoration (screw\u2010retained vs. cement\u2010retained) was evaluated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Material and methods<\/jats:title><jats:p>Sixty patients with a missing anterior tooth in the maxilla were treated with a Straumann Bone Level Implant. Bone augmentation was performed in 29 patients at 3\u00a0months before implant placement. Implants were loaded after 3\u00a0months of submerged healing. Follow\u2010up was conducted at 7 and 18\u00a0months after implant placement. Peri\u2010implant mucosa and implant crown aesthetic outcomes were determined using the Implant Crown Aesthetic Index (ICAI) and the Pink Esthetic Score\u2010White Esthetic Score (PES\u2010WES).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>No implants were lost. At 18\u00a0months after implant placement, mean bone level change was \u22120.10\u00a0\u00b1\u00a00.27\u00a0mm and mean probing pocket depth was 2.57\u00a0mm. No differences were found between augmented and nonaugmented sites (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.28). The ICAI indicated satisfactory mucosa and crown aesthetics in 67% and 75% of the cases, respectively, while the PES score was 14.4. ICAI mucosa (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.004) and PES (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.02) scores were significantly less favourable for augmented sites compared with nonaugmented sites. Patient satisfaction was high (8.9\u00a0\u00b1\u00a01.1 on VAS\u2010score).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>From the present prospective, clinical study, it can be concluded that the Straumann Bone Level Implant shows an excellent survival rate, marginal bone stability and good clinical and aesthetic results. Bone augmentation before implant placement does not lead to more marginal bone loss. However, less favourable pink aesthetic outcomes were found in augmented sites compared with nonaugmented sites, while no differences were found between cement\u2010retained and screw\u2010retained restorations.<\/jats:p><\/jats:sec>","DOI":"10.1111\/j.1600-0501.2012.02486.x","type":"journal-article","created":{"date-parts":[[2012,4,30]],"date-time":"2012-04-30T07:37:54Z","timestamp":1335771474000},"page":"941-948","source":"Crossref","is-referenced-by-count":41,"title":["Performance of the Straumann Bone Level Implant system for anterior single\u2010tooth replacements in augmented and nonaugmented sites: A prospective cohort study with 60 consecutive patients"],"prefix":"10.1111","volume":"24","author":[{"given":"Hendrik J.","family":"Santing","sequence":"first","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery University Medical Center Groningen University of Groningen Groningen the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gerry M.","family":"Raghoebar","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery University Medical Center Groningen University of Groningen Groningen the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arjan","family":"Vissink","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery University Medical Center Groningen University of Groningen Groningen the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laurens","family":"den Hartog","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery University Medical Center Groningen University of Groningen Groningen the Netherlands"},{"name":"Department of Fixed and Removable Prosthodontics University Medical Center Groningen University of Groningen Groningen the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Henny J.
