A clinical technique was developed where the buccal portion of the root is retained to preserve the periodontal ligament and bundle bone. This technique is based on animal studies showing the potential to preserve the facial tissues utilizing this approach. The purpose of this study was to gain more insight regarding the safety of the technique with regard to biological and implant\u2010related long\u2010term complications and to observe the clinical appearance of the peri\u2010implant tissues. Another objective was to evaluate volumetric changes of the affected facial contours in long\u2010term and the esthetic outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Material and Methods<\/jats:title><jats:p>This study is a retrospective case series of 10 consecutive patients with implant replacement between the maxillary first premolars. Impressions were made prior to extraction (t1) and 5\u00a0years post\u2010implant placement (t2). 3D\u2010surface scans of the casts were digitally superimposed for quantitative evaluation of alterations of the facial peri\u2010implant tissue contours and soft tissue recessions. Additionally, clinical data were collected (<jats:styled-content style=\"fixed-case\">PPD<\/jats:styled-content>,<jats:styled-content style=\"fixed-case\"> BOP<\/jats:styled-content>, peri\u2010apical radiographs and photographs).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>All implants healed without adverse events. Peri\u2010implant probing revealed healthy conditions. The comparison of radiographic images showed physiologic bone remodeling at the implant shoulders. Mean tissue loss on the facial side in oro\u2010facial direction was \u22120.21\u00a0\u00b1\u00a00.18\u00a0mm. Average recession at implants was \u22120.33\u00a0\u00b1\u00a00.23\u00a0mm and at neighboring teeth \u22120.38\u00a0\u00b1\u00a00.27\u00a0mm. Mean loss of the marginal bone level at the implant shoulder amounted to 0.33\u00a0\u00b1\u00a00.43\u00a0mm at the mesial and 0.17\u00a0\u00b1\u00a00.36\u00a0mm at the distal aspect of the implants. A mean pink esthetic score of 12 was recorded.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Volumetric analysis showed a low degree of contour changes from extraction and implant placement to the follow\u2010ups. Mucosal recession at the implant restoration was comparable to that of the neighboring teeth. Within the limitations of this descriptive study, the socket shield technique offers reduced invasiveness at the time of surgery and high esthetic outcomes with effective preservation of facial tissue contours. This technique should not be used in routine clinical practice until a higher level evidence in the form of prospective clinical trials is available.<\/jats:p><\/jats:sec>","DOI":"10.1111\/clr.13012","type":"journal-article","created":{"date-parts":[[2017,3,24]],"date-time":"2017-03-24T09:10:26Z","timestamp":1490346626000},"page":"1450-1458","source":"Crossref","is-referenced-by-count":120,"title":["Socket Shield Technique for immediate implant placement \u2013 clinical, radiographic and volumetric data after 5\u00a0years"],"prefix":"10.1111","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2873-3751","authenticated-orcid":false,"given":"Daniel","family":"B\u00e4umer","sequence":"first","affiliation":[{"name":"Private Practice H\u00fcrzeler\/Zuhr Munich Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Otto","family":"Zuhr","sequence":"additional","affiliation":[{"name":"Private Practice H\u00fcrzeler\/Zuhr Munich Germany"},{"name":"Department of Periodontology Johann\u2010Wolfgang Goethe University Frankfurt Frankfurt Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephan","family":"Rebele","sequence":"additional","affiliation":[{"name":"Private Practice Rebele Dinkelsbuhl Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Markus","family":"H\u00fcrzeler","sequence":"additional","affiliation":[{"name":"Private Practice H\u00fcrzeler\/Zuhr Munich Germany"},{"name":"Department of Operative Dentistry and Periodontology Albert\u2010Ludwigs\u2010University Freiburg Freiburg Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,3,23]]},"reference":[{"key":"e_1_2_7_2_1","first-page":"176","article-title":"Conventional immediate implant placement and immediaten placement with socket\u2010shield technique \u2013 Which is better","volume":"1","author":"Abadzhiev M.","year":"2014","journal-title":"International Journal of Clinical Medicine Research"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.19070\/2377-8075-SI05001"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.2005.00642.x"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/cid.12076"},{"key":"e_1_2_7_6_1","first-page":"30","article-title":"Outcome analysis of implant restorations located in the anterior maxilla: a review of the recent literature","volume":"19","author":"Belser U.C.","year":"2004","journal-title":"International Journal of Oral and Maxillofacial Implants"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.2004.00565.x"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1708-8208.2012.00456.x"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0501.1997.080302.x"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/0022-3913(80)90174-2"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/prd.12167"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.11607\/jomi.2014suppl.g3.3"},{"key":"e_1_2_7_13_1","first-page":"23","article-title":"Papilla preservation between two implants: a modified socket\u2010shield technique to maintain the scalloped anatomy?
