PEREIRA G, Álvaro  and  OLIVA M, Patricio. Hydroxyapatite Effectiveness in Healing of Bone Grafts and Dental Implants: A Systematic Review of the Literature. Int. J. Odontostomat. [online]. 2014, vol.8, n.3, pp.425-432. ISSN 0718-381X.

Hydroxyapatite (HA) is a mineral component of bone. The hydroxyapatite has been marketed: synthetic or alloplastic, as porous or nonporous, dense and resorbable or non-resorbable. These are used as bone graft due to their osteoconductive properties and stimulation of cell proliferation that generate favorable conditions for tissue regeneration. The objective of this study was to evaluate the effectiveness of treatment with HA in dental implant surgeries and bone grafts. We conducted a systematic review and studied clinical trials on healing and graft of synthetic hydroxyapatite in PubMed, Cochrane Library, Google Scholar, Blackwell and Ebsco. Selection criteria were: patient's candidate to treatment of periodontal defects or rehabilitation with dental implants without significant systemic abnormalities. The strategy is summarized in the following: Identification of the problem, identifying search terms, systematic search and selection of articles by using critical analysis guides, incorporating REVMAN® information, unbiased analysis, and Meta-analysis. Our results indicate that assessing the meta-analysis shows that the HA is effective for healing bone graft. When omitting low weight studies, the summary measure remains in the HA. In conclusion, treatment with HA in bone healing and dental implants is positive with a high success rate in the long term, although its effective range varies with the materials to which it is associated.
