Abstract
Background: Retrograde peri-implantitis (RPI) is a pathological entity with an unclear etiology (e.g., overheating during implant insertion, residual infection of the tooth replaced by the implant or the endodontic lesion of neighboring teeth) and an extremely low prevalence and has been scarcely investigated. Therefore, the aim of this cross-sectional survey was to evaluate the knowledge and attitude of Italian implantologists regarding RPI. Methods: An anonymous questionnaire was sent via email to implantologists randomly selected, including a section about demographic information and questions related to RPI origin, radiographic representation, symptoms and treatment options. All questions were multiple answer and close-ended. Binomial logistic regression was performed to investigate the relationship between correct answers and the following independent variables: age, years of experience and number of dental implants placed per year. Results: In total, 475 implantologists completed the questionnaire, with a response rate of 46.3%. Based on the results of the study, incorrect answers were associated with less experienced participants (<80 implants/year) for all questions evaluated, with the exception of treatment strategies. Furthermore, 26.7% of the survey takers did not recognize radiographic representation of RPI and 35.5% picked “implant removal” when asked about treatment modality. Conclusions: The majority of participants were able to recognize symptoms and indicated the probable causes of RPI; however, around 30% of them showed very limited knowledge of available management strategies.
Highlights
During the last decades, the replacement of missing teeth with dental implants has become a successful and predictable option for clinicians [1,2,3,4]
Even if all clinicians enrolled in this survey practiced implant dentistry, 26.7% of them ignored the radiographic representation of Retrograde peri-implantitis (RPI) (“a radiolucent area at the apical aspect of the implant”), selecting the wrong answers “a radio-opaque area at the apical aspect of the implant” and
Retrograde peri-implantitis could lead to implant failure if the periapical lesion extends to the marginal bone of the implant
Summary
The replacement of missing teeth with dental implants has become a successful and predictable option for clinicians [1,2,3,4]. Peri-implantitis, characterized by bleeding and/or suppuration on gentle probing and progressive loss of supportive bone around dental implants, represents a well-known cause of implant failure [5,6,7,8]. There is another pathological entity, described as retrograde peri-implantitis (RPI) [9,10,11], which represents a less-known disease [12]. This lesion appears radiographically as a radiolucent area around the apical part of the implant. 26.7% of the survey takers did not recognize radiographic representation of RPI and 35.5% picked “implant removal”
