Abstract
Intraosseous metal implants are used in dentistry to replace lost teeth and to function as artificial roots, where a dental prosthesis could be anchored. The phenomenon of bone tissue growth on the surface of the implant is known as osseointegration, and several strategies are used to improve osseointegration on dental implants, such as modifying surface roughness and increasing the implant surface energy. With the recent popularization of additive manufacturing / 3D printing, there is an increasing interest in the application of this technology on dental implant manufacturing since it offers several advantages such as the development of implants with customized design, porosity and roughness. In the present work, metal additive manufacturing flat surface roughness parameters are evaluated to be used as intraosseous dental implants without the use of posterior surface treatments. The roughness measurements were obtained using a mechanical contact profilometer. The results are compared with data provided in the literate for commercially available implants and show that additive manufacturing is suitable to be used in the dental context in relation to the surface roughness parameters. In addition, a great prospect of this proposal is the possibility of elimination of posterior surface treatments, allowing faster and cheaper production of these implants.
