Objective:
The aim of this study was to evaluate the relationship between the number of
pillar implants of implant-supported fixed prostheses and the prevalence of
periimplant disease.
Material and Methods:
Clinical and radiographic data were obtained for the evaluation. The sample
consisted of 32 patients with implant-supported fixed prostheses in function for
at least one year. A total of 161 implants were evaluated. Two groups were formed
according to the number of implants: G1) ≤5 implants and G2) >5 implants. Data
collection included modified plaque index (MPi), bleeding on probing (BOP),
probing depth (PD), width of keratinized mucosa (KM) and radiographic bone loss
(BL). Clinical and radiographic data were grouped for each implant in order to
conduct the diagnosis of mucositis or peri-implantitis.
Results:
Clinical parameters were compared between groups using Student’s t test for
numeric variables (KM, PD and BL) and Mann-Whitney test for categorical variables
(MPi and BOP). KM and BL showed statistically significant differences between both
groups (p<0 .001="" 19="" 26="" compared="" differences="" from="" g1="" g2="" implants="" of="" p="0.0210).</p" peri-implantitis="" prevalence="" regarding="" showed="" significant="" statistically="" the="" with="">
