BLANCO LOPEZ, P et al. Osseointegration of titanium implant with several rough surfaces. Av Odontoestomatol [online]. 2018, vol.34, n.3, pp.141-149. ISSN 2340-3152.

Implant surface is very important for enhance the osseointegration. They are many types of dental implant surfaces. Implant surface research begins with machined surface. Roughened surface titanium increase cell adhesion and exhibit stronger bone-implant contact area. Plasma-spray and hydroxyapatite coating were common methods for rough surface modification. Most recently, blasting (i.e. alumina) and acid-etching (i.e. hydrochloric, sulphuric and nitric) are another process by which surface roughness can be increased. Most recently, technology begins in implant dentistry with the development of porous surfaces that manifest better osteogenic response and increase bone-titanium mechanical interlocking. Osseointegration appeared to be strongly influenced by the animal species model. The rabbit model was faster compared to the dog model, and the dog model was faster the human model. The introduction of new materials and new technical process in dental surfaces research offering new possibilities for better tissue response and bone regenerative potential.
