Brief Summary

The goal of this observational study invitro study was to compare the different cementation techniques used to lute full veneer crowns on extracted and prepared teeth using Glass Ionomer Cement type 1. The main question\[s\] it aims to answer are: The in-vitro effect cement application techniques on retention of full veneer crowns. Which of the three different cementation techniques in-vitro provide a greater retention for a full veneer crown and will it achieve better retention using the concluded method for longer duration of cemented crown in oral cavity. To use of adequate amount of cement to avoid wastage. The principal investigator applied the Glass ionomer cement in three different techniques on custom prepared crowns and with the help of an Universal Testing Machine debonded the crown from the prepared tooth. The results were compared amongst the three categories and the technique C, proved to be the superlative amongst the three.

Conditions

Cementation Teeth; Hyperplasia; Dental Cements; Tooth Crown Fracture

Keywords

Cementation; Cementation techniques; Crowns; Glass-ionomer cement; Retention

Outcome Measures

Primary Outcomes (1)

• Cementation technique A,B and C

  1. Filling the crown with cement up to margins. 2. Applying a cement layer on all fitting surfaces. 3. Applying a cement layer on all fitting surfaces except occlusal surface. Each of the aforementioned groups exhibits distinct measures of tensile strength. Each group will be compared with one another in terms of the cementation technique used, specifically in relation to Newton force. A questionnaire was not employed for comparative purposes among the three groups; instead, the unit of force (Newton) was utilized to compare each group.
