Micrometric characterization of the implant surfaces from the five largest companies in Brazil, the second largest worldwide implant market.

Purpose: To characterize the surface of implants from Brazilian companies by light interferometry and evaluate the level of control of the surface treatment process.

Materials And Methods: Oral implants from the five largest Brazilian companies were evaluated topographically. The surfaces of the implants were analyzed on the tops, valleys, and flanks of the threads, totaling nine measurements for each unit.

Retrospective study of the anterior loop of the inferior alveolar nerve and the incisive canal using cone beam computed tomography.

Purpose: The mental foramen is an important landmark during surgical procedures such as osseous grafting or the placement of dental implants. To avoid injuring the mental nerve, it is important both to carefully assess the location of the mental foramen and to determine whether an anterior loop of the mental nerve or the incisive canal lies mesial to it. The objective of this study was to quantify the ability of cone beam computed tomography (CBCT) to measure the length of the mental nerve loop, the length and diameter of the incisive nerve canals, and the incisive canal path.

The influence of surface treatment on the implant roughness pattern.

Unlabelled: An important parameter for the clinical success of dental implants is the formation of direct contact between the implant and surrounding bone, whose quality is directly influenced by the implant surface roughness. A screw-shaped design and a surface with an average roughness of Sa of 1-2 µm showed a better result. The combination of blasting and etching has been a commonly used surface treatment technique.
