Abstract

Introduction: The use of dental implants is a widely accepted treatment modality for fully and partially edentulous patients. The beginning of the year 2000 brought the development of moderately rough implant surfaces and macro-designs that are nowadays considered to represent the gold standard for implant treatment. The purpose of this retrospective cohort study was to present long-term data more than 10 years, on survival rate, marginal bone level changes and peri-implant soft tissue healthy status of 709 patients with 864 dental implants in fully and partially edentulous cases.

Material and Methods: The aim of this retrospective open cohort study was to show long-term survival data, and evaluation of several covariates such as marginal bone level changes, peri-implant soft tissue status monitored on 864 dental implants.

Patients who underwent dental implant surgery between January 2003 and September 2008, were investigated. A total of 709 patients treated in 3 different private practices. All the implants were loaded with fixed metal-ceramic or zirconium-ceramic crowns. No removable prostheses were included. X rays and clinical examinations were performed at baseline and yearly for each follow-up visit. Marginal bone level (MBL), Probing Pocket Depth (PPD), Bleeding on Probing (BOP) were assessed.

Results: During the study period there were 9 implant failures (0,9%) and 3 patients (with 7 implants) were drop-outs. The final implant survival rate was of 98% after more than 10 years of follow-up. Considering BOP at the last control visit, 210 implants were positive (24%), 635 (74,5%) negative and 10 (1,5%) was diagnosed with peri-implantitis. The median PPD for implants with negative BOP was of 3.04 mm while for the implants with positive BOP, with presence of mucositis, the median PPD was 3,75mm.For the implants with peri-implantitis the mean value was 5.1mm.

Conclusion: Within the limitation of this study, a low rate of failures and incidence of peri-implantitis was recorded. No relation is present between the failure of the implants and the loading protocols: implants placed immediately or delayed after tooth extraction show similar survival rates and peri-implant marginal bone resorption.
