Surface modifications on titanium, zirconia and peek implants. Dental implants

      Аннотация: The book discusses briefly about the modifications that are created on the implant surfaces to enhance the osseointegration for better results. Newer materials PEEK have also been discussed which is a very new discovery and biocompatible. Surface modification mostly improves clot wettability, cell-implant adhesion, proliferation, and osseointegration, all of which contribute to the end of shorter healing time. Surface wettability describes the contact angle of a hydrophilic substance as it spreads out over to the surface of the interface in question (titanium). It is directly proportional to a substance’s hydrophilicity and is a key factor in osseointegration in that cell migration and adhesion to an implant’s surface is driven by adsorption of osteogenic proteins at the surface of the implant. These proteins have a higher affinity with hydrophilic surfaces rather than hydrophobic surfaces. While many different surface modification methods exist, they can be subdivided into two broad categories: additive methods and subtractive methods.
