Correlation between clinical parameters characterising peri-implant and periodontal health: a practice-based research in Spain in a series of patients with implants installed 4-5 years ago.

Objectives: To explore peri-implant health (and relation with periodontal status) 4-5 years after implant insertion.

Study Design: A practice-based dental research network multicentre study was performed in 11 Spanish centres. The first patient/month with implant insertion in 2004 was considered.

Effect of oral bacteria on the mechanical behavior of titanium dental implants.

Purpose: This study sought to determine whether the mechanical properties of titanium dental implants changed after exposure to bacteria.

Materials And Methods: Two strains of bacteria (Streptococcus sanguinis and Lactobacillus salivarius) were used in the study. The adhesive properties of the two strains were investigated as follows.
