Mechanical behavior of dental implants in different positions in the rehabilitation of the anterior maxilla.

Statement Of Problem: In dental rehabilitations that involve implants, the number of implants is sometimes smaller than the number of lost teeth. This fact can affect the biomechanical behavior and success of the implants.

Purpose: The purpose of this study was to investigate the mechanical behavior of different implant positions in the rehabilitation of the anterior maxilla.

Fatigue and fluoride corrosion on Streptococcus mutans adherence to titanium-based implant/component surfaces.

Purpose: The influence of fatigue and the fluoride ion corrosion process on Streptococcus mutans adherence to commercially pure Titanium (Cp Ti) implant/component set surfaces were studied.

Materials And Methods: Thirty Nobel implants and 30 Neodent implants were used. Each commercial brand was divided into three groups.

Influence of a fluoridated medium with different pHs on commercially pure titanium-based implants.

Purpose: The objective of this study was to assess the influence of a fluoride medium with different pHs on the corrosion resistance of three commercially pure titanium-based dental implant commercial brands, under scanning electron microscopy (SEM) and EDS.

Materials And Methods: Forty-two dental implants, from three commercial brands, were used. Five years of regular use of mouth rinsing, with NaF 1500 ppm content and two different pHs, were simulated by immersing the specimens into that medium for 184 hours.
