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.
