The primary purpose of the study is to evaluate and compare the frequency of cement and screw-retained restorations among implant practicing dental professionals in India in institutes and government and private practices.
Patients and method
A cross-sectional observational study by means of a virtual survey was conducted in India to evaluate the frequency of use of screw and cement-retained retention systems in implant prostheses. The descriptive survey included questions regarding the type of practice i.e., government or private, as well as their specialties. The descriptive statistical analysis was conducted through counts and percentages and by using online software IBM SPSS Statistics (Version 24.0. IBM Corp., Armonk, New York, USA). The significance level was set as less than .05.
Results
The total number of responses collected in the survey was 405, out of which 89.1% of the participants were MDS graduates of whom 48.6% were working in institutions, either private or government. The majority respondents included Prosthodontists (66.9%) and most of them were currently in institution (34%). Cement-retained retention system was most preferred (59.0%) for restoring anterior crowns and bridges, whereas screw-retained was the most preferred retention system for restoring posterior crowns and bridges (65.2%) and for full arch implant supported prostheses (75.3%).
Conclusion
The study concluded that the use of cement-retained prostheses was favoured more in the anterior region, while screw-retained prostheses was favoured in the posterior region. The most common complication in screw-retained prostheses was loosening of screw, while deboning of prostheses was common with cement retained restorations. Based on the responses, it can be concluded that posterior regions are more prone to complications compared to anterior implant restorations.
