However, clinical results have shown that hydroxyapatite may require biological modification with a bone resorption\u2010inhibiting agent which may be beneficial for maintenance of alveolar bone. We conducted experimental and clinical studies to evaluate the effect of highly bisphosphonate\u2010complexed hydroxyapatite implants on osteoconduction and repair in alveolar bone.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Methods:<\/jats:bold>\n                    Porous hydroxyapatite implants were pre\u2010incubated in 10\n                    <jats:sup>\u22122<\/jats:sup>\n                    M bisphosphonate solutions at pH 3.49. The implants had a diameter of 2.1 mm and a height of 2 mm and adsorbed 115 \u00b5g bisphosphonate. Five goats were implanted with 4 plain hydroxyapatite implants on each side of the mandible in root extraction sockets for the precision analysis of dual x\u2010ray absorptiometry (DEXA) measurements. Ten goats were implanted with 4 bisphosphonate\/hydroxyapatite implants on one side of the mandible and 4 plain hydroxyapatite implants on the opposite mandible. In a clinical study, 23 bisphosphonate\/hydroxyapatite implants were placed in periodontally destroyed tooth root sockets and followed up during one year.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    The range for the bone mineral density (BMD) measurement errors for goat histologic sections was 0.48% to 1.03%. There were large differences in peri\u2010implant BMDs in the left and right mandible of the same goat, irrespective as to whether hydroxyapatite or bisphosphonate\/hydroxyapatite implants were present. This was due to local anatomical differences typical of alveolar bone. These differences were not significant. Histologically, all bisphosphonate\/hydroxyapatite as well as hydroxyapatite controls appeared to be fully integrated and effective as bone replacement material in goat alveolar bone. They exhibited vascularization and osteoconduction of alveolar bone growth along and inside their porous structure. In patients peri\u2010implant healing was clinically and radiographically comparable to plain hydroxyapatite implants. All implants were retained and no dehiscences developed. Radiographically, peri\u2010implant radiolucencies disappeared and alveolar bone was deposited in close proximity to the implants.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions:<\/jats:bold>\n                    This study contributes to the understanding of the biological properties of hydroxyapatite implants as carriers for the bone\u2010modulating agent bisphosphonate. Our study suggests that normal osteoconduction and repair occurred in alveolar bone around the highly bisphosphonate\u2010complexed hydroxyapatite implants.\n                    <jats:italic>J Periodontol 2000;71:279\u2010286.<\/jats:italic>\n                  <\/jats:p>","DOI":"10.1902\/jop.2000.71.2.279","type":"journal-article","created":{"date-parts":[[2005,2,2]],"date-time":"2005-02-02T06:24:01Z","timestamp":1107325441000},"page":"279-286","source":"Crossref","is-referenced-by-count":30,"title":["Alveolar Bone Response to Submerged Bisphosphonate\u2010Complexed Hydroxyapatite Implants"],"prefix":"10.1002","volume":"71","author":[{"given":"Harry","family":"Denissen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristiana","family":"Montanari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberta","family":"Martinetti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arthur","family":"van Lingen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arnold","family":"van den Hooff","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2000,2]]},"container-title":["Journal of Periodontology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/pdf\/10.1902\/jop.2000.71.2.279","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,19]],"date-time":"2025-10-19T11:57:31Z","timestamp":1760875051000},"score":1,"resource":{"primary":{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/10.1902\/jop.2000.71.2.279"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2000,2]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2000,2]]}},"alternative-id":["10.1902\/jop.2000.71.2.279"],"URL":"https:\/\/doi.org\/10.1902\/jop.2000.71.2.279","archive":["Portico"],"relation":{},"ISSN":["0022-3492","1943-3670"],"issn-type":[{"value":"0022-3492","type":"print"},{"value":"1943-3670","type":"electronic"}],"subject":[],"published":{"date-parts":[[2000,2]]}}}
