简要总结
Fixed dental prostheses are widely used to replace missing teeth. A crucial factor for their success is a good marginal fit, which prevents issues like micro-leakage and gum problems.
With advancements, dentists now have various materials for fixed partial denture. This study aims to compare 3D-printed resin crowns with milled composite crowns. While milled crowns have limitations, 3D printing offers better control and precision.
There’s no existing data on the clinical performance of 3D-printed permanent fixed partial denture. This study will evaluate how well 3D-printed resins compare to milled composite crowns in terms of marginal fit, gum health, and overall performance over a year.
The hypothesis is that 3D-printed resins may lead to better clinical outcomes due to potentially superior marginal fit.
The study will compare 3D-printed resin crowns with milled composite crowns for single tooth restoration.
Steps include:
-
Screening patients and obtaining consent.
-
Randomly assigning patients to either group (3D-printed or milled crowns).
-
Preparing the teeth for crowns.
-
Taking digital impressions and designing crowns.
-
Fabricating crowns (3D-printed or milled).
-
Evaluating marginal fit of the crowns.
-
Cementing the crowns.
-
Monitoring patients’ gums and plaque buildup for 1 year.
-
Evaluating the clinical performance of the crowns for 1 year.
-
Analyzing the data.
