Introduction:
Growing aspect of endosseous implant research is focused on surface modification of dental implants for the purpose of improving osseointegration. The aim of this study was to evaluate and compare the clinical outcome (ie, osseointegration) of hydroxyapatite coated, bioactive glass coated and machined titanium alloy threaded dental implants in human jaw bone after implantation.
Materials And Methods:
One hundred twenty-six implants (45 hydroxyapatite coated, 41 bioactive glass coated, and 40 machined titanium implants) have been placed in incisor areas of 62 adult patients. Outcome was assessed up to 12 months after prosthetic rehabilitation using different clinical and radiological parameters. Surface roughness of failed implants was analyzed by laser profilometer.
Discussion:
Hydroxyapatite and bioactive glass coating materials were nontoxic and biocompatible. Least marginal bone loss in radiograph, significantly higher (P < 0.05) interface radiodensity, and less interfacial gaps were observed in computed tomography with bioactive glass coated implants at anterior maxilla compared to other 2 types.
Conclusion:
Bioactive glass coated implants are equally safe and effective as hydroxyapatite coated and machined titanium implants in achieving osseointegration; therefore, can be effectively used as an alternative coating material for dental implants.
