Two animals each were killed at 20, 40, and 60 weeks of observation periods. The mandibular jaw segments were prepared in toto for light microscopy by resin embedding and serial ground sectioning. Additionally, one \u03b2-TCP-treated socket at 60 weeks was thoroughly investigated by correlative light, electron microscopic and electron probe X-ray microanalysis to assess the bioabsorbability and host removal of the replica material from the implant site. The extraction wounds of the animals healed satisfactorily with very little histologically observable differences in the healing pattern of the test and control sites. The \u03b2-TCP was completely removed from extracellular sites, but at 60 weeks, remnants of it were found in the cytoplasm of multinucleated giant cells. The root replicas made out of \u03b2-TCP were biocompatible and bioabsorbable. Osseous healing occurred both in the test and control sockets, but the healing process was delayed due to the presence of \u03b2-TCP particles.\n                  <\/jats:p>","DOI":"10.1177\/0885328206054167","type":"journal-article","created":{"date-parts":[[2006,3,30]],"date-time":"2006-03-30T07:08:02Z","timestamp":1143702482000},"page":"307-324","source":"Crossref","is-referenced-by-count":17,"title":["Biocompatibility of b-Tricalcium Phosphate Root Replicas in Porcine Tooth                 Extraction Sockets - A Correlative Histological, Ultrastructural, and X-ray                 Microanalytical Pilot Study"],"prefix":"10.1177","volume":"20","author":[{"given":"P.N.R.","family":"Nair","sequence":"first","affiliation":[{"name":"Institute of Oral Biology, Section for Oral Structures and Development,                         Centre of Dental and Oral Medicine, University of Zurich, Zurich,                         Switzerland,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hans-Ulrich","family":"Luder","sequence":"additional","affiliation":[{"name":"Institute of Oral Biology, Section for Oral Structures and Development,                         Centre of Dental and Oral Medicine, University of Zurich, Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabrizio A.","family":"Maspero","sequence":"additional","affiliation":[{"name":"Department of Materials, Swiss Federal Institute of Technology (ETH),                         Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00fcrgen H.","family":"Fischer","sequence":"additional","affiliation":[{"name":"Institute of Experimental Medicine, University of K\u00f6ln,                         K\u00f6ln, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jens","family":"Schug","sequence":"additional","affiliation":[{"name":"Clinic for Preventive Dentistry, Periodontics and Cariology, Centre of                         Dental and Oral Medicine, University of Zurich, Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2006,4,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1016\/S0278-2391(96)90113-5"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.14219\/jada.archive.1960.0152"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3913(98)70116-7"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1016\/0022-3913(71)90070-9"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1016\/0022-3913(62)90125-7"},{"key":"atypb6","doi-asserted-by":"publisher","DOI":"10.1016\/0030-4220(88)90129-6"},{"key":"atypb7","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1998.69.4.414"},{"key":"atypb8","doi-asserted-by":"publisher","DOI":"10.1016\/0278-2391(84)90347-1"},{"key":"atypb9","doi-asserted-by":"publisher","DOI":"10.1177\/089875649501200201"},{"key":"atypb10","first-page":"393","volume":"12","author":"Froum, S.","year":"2000","journal-title":"Pract.
