The specimen was processed for histologic\/histomorphometric evaluation.<jats:italic> Results.<\/jats:italic> The buccal bone plate was maintained without any resorption; a healthy periodontal ligament was evidenced. The implant showed osseointegration, with a high percentage of bone-to-implant contact (BIC = 76.2%). With regard to the space between the RM and the implant, the apical and medial thirds were filled with compact, mature bone; the coronal third was colonized by noninfiltrated connective tissue.<jats:italic> Conclusions.<\/jats:italic> The RM technique appears to be effective in preventing bone resorption of the buccal bone plate of the human anterior maxilla, five years after the placement of an immediate implant.<\/jats:p>","DOI":"10.1155\/2017\/7269467","type":"journal-article","created":{"date-parts":[[2017,11,22]],"date-time":"2017-11-22T18:31:42Z","timestamp":1511375502000},"page":"1-8","source":"Crossref","is-referenced-by-count":52,"title":["The Root Membrane Technique: Human Histologic Evidence after Five Years of Function"],"prefix":"10.1155","volume":"2017","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0795-0864","authenticated-orcid":true,"given":"Miltiadis E.","family":"Mitsias","sequence":"first","affiliation":[{"name":"Department of Periodontology and Implant Dentistry, College of Dentistry, New York University, New York, NY 10010, USA"},{"name":"Private Practice, Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Konstantinos D.","family":"Siormpas","sequence":"additional","affiliation":[{"name":"Private Practice, Larissa, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Georgios A.","family":"Kotsakis","sequence":"additional","affiliation":[{"name":"Division of Periodontology, School of Dentistry, University of Minnesota, Minneapolis, MN 55455, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Scott D.","family":"Ganz","sequence":"additional","affiliation":[{"name":"Rutgers School of Dental Medicine, Newark, NJ 07103, USA"},{"name":"Hackensack University Medical Center, Hackensack, NJ 07601, USA"},{"name":"Private Practice, Fort Lee, NJ 07024, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4419-4674","authenticated-orcid":true,"given":"Carlo","family":"Mangano","sequence":"additional","affiliation":[{"name":"Department of Dental Sciences, Vita and Salute University S.
