Abstract:

OBJECTIVE: The objective of this current study was to identify the most effective method for cementing crowns with glass ionomer cement that would maximize retention. METHODOLOGY: This in-vitro study was carried out by collecting 120 extracted human premolar teeth which were mounted on an acrylic block and prepared with specific total occlusal convergence and height. Metal crowns for the models were casted and cemented on the prepared premolar teeth by using three cementation techniques A) filling the crown with cement up to margins, B) applying a cement layer on all fitting surfaces and C) applying a cement layer on all fitting surfaces except occlusal surface. The force to crown dislodgment was measured and recorded in Newtons (N). Higher force was indicative of better retention. Data were analyzed using SPSS version 25. p-value less than 0.05 was considered of statistical significance. RESULTS: The median retention load in Category C 'cementation except occlusal surface' (Median=15.04 N) was significantly higher than median retention load in Category A (Median=4.34 N) and Category B (Median=14.20 N) (p<0.001). Posthoc analysis showed that there was significant difference between retention of the three cementations technique A (p<0.001), B (p<0.001) and C (p=0.022). CONCLUSION: There was significant difference in retention of full veneer metal crowns when three different cementation techniques were used. Retention was best when surface area was optimally maximum, cement was applied in thin layer, and cement had enough space to flow between the tooth and crown surface,. Maximizing surface area and increasing cement volume resulted in poor retention. However, applying cement in thin layer but with maximum surface area resulted in better retention.
