Peri-implantitis, a disease affecting dental implants, shows an accelerating bone loss pattern. Most cases begin within three years of implant function, highlighting the need for early intervention strategies.
Area of Science:
- Dental Implantology
- Periodontology
- Biostatistics
Background:
- Limited data exists on the onset and progression of peri-implantitis, despite known prevalence.
- Understanding disease dynamics is crucial for effective management of peri-implant conditions.
Purpose of the Study:
- To investigate the onset and progression patterns of peri-implantitis using longitudinal data.
- To model the rate of marginal bone loss in patients with peri-implantitis.
Main Methods:
- A 9-year follow-up study of 596 implant recipients.
- Identified 62 patients with moderate/severe peri-implantitis.
- Utilized multilevel growth models to analyze longitudinal marginal bone levels and estimate bone loss patterns.
Main Results:
- Peri-implantitis exhibited a non-linear, accelerating pattern of bone loss.
- Early onset was observed, with 52% and 66% of implants showing >0.5 mm bone loss by years 2 and 3, respectively.
- By year 3, 70% and 81% of subjects had at least one implant with >0.5 mm bone loss.
Conclusions:
- Peri-implantitis progression is characterized by non-linear, accelerating bone loss.
- The onset of peri-implantitis typically occurs within the first three years of functional loading.
- Findings underscore the importance of early detection and intervention for peri-implantitis.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
