The prevalence of peri‐implant diseases for two‐piece implants with an internal tube‐in‐tube connection: a cross‐sectional analysis of 512 implants

OBJECTIVES: To assess the prevalence of peri-implant health or disease for a two-piece implant system with a tube-in-tube internal connection on the short-, medium- and long term. MATERIAL AND METHODS: For this cross-sectional analysis, 238 patients with a total of n = 512 implants were screened in six private practices and one university clinic in Germany. Peri-implant health and disease was assessed according to strict case definitions. Binary logistic regression was used to assess the correlation with systemic factors. RESULTS: After a median function time of 23 months, the prevalence of peri-implant mucositis and peri-implantitis amounted to 41.6% and 13.9%, corresponding to 35.6% and 7.6% at the implant level, respectively. Factors plaque (odds ratio [OR], 8.415) and gender "male" (OR, 2.003) were significantly correlated with the event peri-implant mucositis. The event peri-implantitis was significantly correlated with plaque (OR, 9.250) and smoking (OR, 2.679). CONCLUSION: The prevalence of peri-implant diseases was correlated with patient-specific factors.
