Introduction:
Resin-bonded fixed dental prostheses have an advantage over conventional fixed dental prostheses in terms of conservation of tooth structure but many clinicians refrain from using this treatment plan over the concern of the retention of those prostheses. In anterior region, it has better survival rate because of the less masticatory force. This study was conducted to find out the survival of resin-bonded fixed metal-ceramic dental prostheses placed in anterior region of a tertiary care hospital.
Methods:
A descriptive cross-sectional study was carried out in a tertiary care hospital from September 2020 to February 2021. Ethical approval was taken from the Institutional Review Committee of Kantipur Dental College (reference number: 29/020). One hundred fifty-five patients who underwent prosthesis placement at least 5 years ago in the institution were identified from the hospital record and called, out of which only 80 agreed to be enrolled in the study. Consent was taken and data were collected using questionnaires filled by investigators and analyzed using the Statistical Package for the Social Sciences version 25. Point estimate at 90% Confidence Interval was calculated along with frequency and percentage for binary data.
Results:
Out of 80 patients, the prostheses survived in 72 (90%) (90% Confidence Interval 84.48-95.51). The mean duration for which the prostheses survived in the mouth was 73.33±13.493 months with minimum 28 and maximum 98 months.
Conclusions:
This study showed that the survival after five years of resin-bonded fixed dental metal ceramic was high. The study's findings are comparable with international studies.
