Aim And Objective:
Peri-implantitis is a key concern for dental implants and the main common reason for implant failure. This investigation evaluated the risk factors and their implications on peri-implantitis.
Materials And Methods:
A retrospective search of the patients' clinical notes was performed to identify the documented cases of peri-implantitis. The inclusion criteria encompassed patients who were 18 years and older and were seen at the School of Dental Medicine, University of Nevada, Las Vegas, from January 2014 through September 2018. The search revealed that the number of peri-implantitis cases was 28, with an overall 45 implants. Data were collected and analyzed using the Chi-square test.
Results:
Total 28 patients presented with peri-implantitis. The distribution of males to females with peri-implantitis was 60.7 and 39.3%, respectively. The highest number of patients (21.4%) presenting with peri-implantitis fell within the age range of 65-69 years; 53.3% of peri-implantitis cases were in the maxillary arch. The predilection area for peri-implantitis was the mandibular first molar (24.4%). Periodontitis was the most significant cause (60.7%); respiratory diseases (42.9%) followed by hypertension (28.6%) were the most prevalent medical conditions in the studied population. Peri-implantitis occurred most frequently among Caucasians (62.7%), followed by Hispanics (29%).
Conclusion:
Within the limitations of the current evaluation, findings support previous claims that periodontitis remains the strongest predictor of peri-implantitis. A correlation may exist between peri-implantitis and the location of the implant and respiratory disease.
Clinical Significance:
The implant location, the presence of periodontitis, and respiratory diseases are considered to be risk factors for peri-implantitis.
