RESUMO

STATEMENT OF PROBLEM: Knowledge of the effectiveness of hydroxyapatite coatings on the surface of titanium dental implants is lacking because of difficulties in standardizing their thickness, roughness, and effect on osseointegration. The selection of articles describing this coating in osseointegration will be of great relevance to implant dentistry. PURPOSE: This systematic review aimed to answer the question, "How effective is hydroxyapatite on titanium surfaces for osseointegration?" MATERIAL AND METHODS: The Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020 guidelines were followed, and the protocol was registered on the international prospective register of systematic reviews (PROSPERO) database (CRD42023422601). The PubMed, Scopus, Web of Science, and Embase databases were searched, and articles were selected manually in 2 steps by 2 blinded investigators according to the previously selected eligibility criteria. The risk of bias was assessed using the systematic review center for laboratory animal experimentation (SYRCLE) tool. RESULTS: Initially, 671 results were found. After analysis of eligibility criteria and full reading, 15 articles were included in the present review. Of these, 12 reported favorable osseointegration results for hydroxyapatite-coated surfaces, and 3 found no significant long-term difference between the coated and uncoated groups. CONCLUSIONS: Hydroxyapatite surface treatment is effective in the osseointegration of titanium dental implants because it favors the absorption of proteins, adhesion, and proliferation of bone cells when obtained by methods that ensure proper adhesion.
