Proximal Contact Points between Fixed Dental Restorations during Bisque Trial Stage

Abstract

Introduction
Proper proximal contact points between a crown and adjacent teeth plays an important role in the gingival health and longevity of the prosthesis. This study was conducted to assess the proximal contact points between a metal ceramic crown and adjacent teeth in bisque trial stage.

Methods
A cross-sectional study was conducted in a total of 75 maxillary and mandibular 1st molar crowns to assess the type of contact points present on the mesial and distal side by using a dental floss. The contact points were categorized as being either open, acceptable or too tight. Descriptive statistical analysis (frequency and percentage) was done using SPSS Statistical Software Package (version 21.0).

Results
In this study 75 crowns were studied to assess the proximal contact points in 150 ( 75 mesial and 75 distal ) sites. A total of 24 (16%) sites showed open contact points, 47 (31.33%) showed acceptable contact points and 79 (52.66%) sites showed too tight contact points.

Conclusion
A significant number of crowns showed open and too tight type of contact points. These can be rectified before final cementation since the assessment was done during the bisque trial stage.
