Peri-Implant Mucosal Inflammation and Bone Loss: Clinical and Radiographic Evaluation of 108 Dental Implants After 1-Year Loading

Zhihui Tang, DS, PhD/Yueqin Sha, DDS, MS/Ye Lin, DDS, MD/Gang Zhang, DDS, MS/Xin Wang, DDS, PhD/Caifant Cao, DDS, MS

Objective: To evaluate the clinical outcomes, and a possible correlation between peri-implant mucosal inflammation and marginal bone loss, 1 year after restoration in a group of Chinese patients with dental implants. Methods: Observation of the clinical and radiographic parameters of 108 IMZ and Frialit-2 dental implants in 70 patients. Results: One year after loading, there were no signs of mobility and peri-implant radiolucency in any of the implants. The average bone loss adjacent to implants was 0.63 mm(SD 0.78). The prevalence of peri-implant mucosal inflammation, as indicated by sulcus bleeding index (SBI) of 1.0 or more, was 32.9%. Significant positive correlation was found betweel mucosal inflammation and bone loss (P<0.05). 92% of the observed sites had plaque index (LI) scores greater than 1. Conclusions: The 1-year outcomes from this patient group indicate that IMZ and Frialit-2 implants provide satisfactory clinical results. One of the etiologic factors of alveolar bone loss around implants seems to be plaque-associated marginal inflammation. Improvement of oral hygiene, elimination of soft tissue inflammation, and proper tretment of periodontal disease of natural teeth are critical for maintaining the implants.
