RESUMO

The aim of this study was to identify potential risk factors for periimplantitis based on data collected from a private clinic in Campina Grande-PB. Information collected from dental charts included patient sex, age and time period since installation of the implant or prosthesis. Clinical examination was carried out at each implant site where health conditions of surrounding mucosa, as well as, probing depth, and bleeding on probing was assessed. Digital radiography was used to measure the distance between implant-abutment gap and mesial and facial surfaces of the alveolar crest. Based on a total of 107 implant sites, Pearsons test did not reveal significant correlations between mean bone loss and age (r= -0.07; p= 0.4) or time period of implant or prosthesis installation (r= -0.14;p= 0.1). A significant association was observed between cemented prostheses and detection of periimplantitis according to the diagnosis criteria used in this study (p=0.002 Chi-square test, OR=5.15) and also highest values of bone loss (p=0,001 Student T test). Implants with bleeding on probing had also highest values of probing depth (p<0,0001) and bone loss (p=0,002). Other risk factors investigated were subgingival localization of the implant-abutment gap and localization of the implants within the dental arch. None of theses variables presented statistically significant correlations. The results of this study suggest that cemented prostheses may be potential risk factors for periimplantitis.
