The vertical bone gain, graft stability, and marginal bone loss were measured radiographically.

After an average healing time of 148\u00a0days, 220 implants were placed in 74 procedures. Perioperative complications included intraoperative fracture (1\/75), transient paresthesia (18\/75), wound healing disturbance (18\/75), and keratinized tissue deficiency (14\/75). The average vertical bone gain was 5.4\u00a0mm at the time of implant placement. Significant marginal bone loss occurred during the first 6\u00a0months, after which the resorption remained stable. The implant survival rate was estimated as 96.7%, and the success rate was 95.3%. Implant survival and success showed no significant correlation with higher age, anticoagulation therapy, cardiovascular disease, or thyroid disorder. Smoking was correlated with significant lower success rate.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Sandwich osteotomy is a suitable augmentation procedure for atrophic mandible, allowing for implant placement with promising outcome.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/clr.13516","type":"journal-article","created":{"date-parts":[[2019,7,29]],"date-time":"2019-07-29T13:09:35Z","timestamp":1564405775000},"page":"1027-1037","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Sandwich osteotomy in atrophic mandibles: A retrospective study with a 2\u2010 to 144\u2010month follow\u2010up"],"prefix":"10.1111","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5393-1675","authenticated-orcid":false,"given":"Yuan\u2010ming","family":"Geng","sequence":"first","affiliation":[{"name":"Department of Stomatology, Zhujiang Hospital Southern Medical University Guangzhou China"},{"name":"Department of Oral and Maxillofacial Surgery Red Cross Hospital Kassel Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miao","family":"Zhou","sequence":"additional","affiliation":[{"name":"Key laboratory of Oral Medicine, Guangzhou Institute of Oral Disease Stomatology Hospital of Guangzhou Medical University Guangzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patricia","family":"Parvini","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery Red Cross Hospital Kassel Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastian","family":"Scarlat","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery Red Cross Hospital Kassel Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hendrik","family":"Naujokat","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery University Hospital of Schleswig\u2010Holstein Kiel Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sophia Mulugeta","family":"Abraha","sequence":"additional","affiliation":[{"name":"Private Practice K\u00f6ln Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0709-114X","authenticated-orcid":false,"given":"Hendrik","family":"Terheyden","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery Red Cross Hospital Kassel Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,8,31]]},"reference":[{"key":"e_1_2_5_2_1","first-page":"11","article-title":"The long\u2010term efficacy of currently used dental implants: A review and proposed criteria of success","volume":"1","author":"Albrektsson T.","year":"1986","journal-title":"International Journal of Oral and Maxillofacial Implants"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.aanat.2015.07.004"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijom.2010.03.002"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joms.2010.10.054"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0501.1990.010105.x"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/clr.12186"},{"key":"e_1_2_5_8_1","volume-title":"Ridge augmentation procedures in implant patients: A staged approach (ITI Treatment Guide Volume 7)","author":"Cordaro L.","year":"2013"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/joor.12605"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/clr.12985"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.11607\/jomi.4861"},{"key":"e_1_2_5_12_1","first-page":"103","article-title":"Implant prosthodontics in medically challenged patients: The university of toronto experience","volume":"68","author":"Elsubeihi E.
