Abstract

Objectives: To investigate the prevalence of open contacts between single implant-supported fixed protheses and adjacent natural teeth and to evaluate the risk factors associated with interproximal contact loss (ICL). Subjects and methods: 126 single implant-supported fixed prostheses in 82 patients (41 males and 41 females) were included in the study. Clinical examinations were performed to assess the prevalence and risk factors of interproximal contact loss relating to patient (age, sex), implant prosthesis (delivery time, restoration material, location) and adjacent tooth (mesial or distal side, restored or original crown). Patients were asked about their feeling of food impaction then the concerns were re-examined by researchers, using waxing dental floss to confirm the presence of food debris. Periapical radiographs were used to investigate the crestal bone loss at the interproximal contact points. Results: Interproximal contact loss has occurred in 23.1% cases, Mesial contact points were significantly more prone to ICL than distal ones (p=0.000, 95%CI). Delivery time and food impaction had a significant effect on ICL. Meanwhile, implant location, patient’s sex and age were not significant risk factors of ICL. Conclusions: Interproximal contact loss is a frequent complication with many related factors. However, its importance has been underestimated.
