Abstract: A dental material formed by using a hydroxyapatite, which is suitable for performing a guided bone regeneration (GBR) method in the implant therapy of dentistry. Also, a composite dental material which is a bioabsorbable film provided integrally with hydroxyapatite is capable of rapidly attracting osteoblast and blocking fibroblast. The dental material is a membrane for a guided bone regeneration method of guiding a bone formation by preventing invasion by anaplastic fibroblast by covering a bone developing site with a blocking membrane and filling the bone developing site with osteoblast, wherein a main body of the blocking membrane is formed by using hydroxyapatite having osteoconductive capability of rapidly attracting osteoblast for the purpose of disposing the hydroxyapatite at a bone developing site side of the membrane main body.
