IMPACT RESISTANCE OF FRAGMENT BONDED ANTERIOR TEETH

This in vitro study evaluated the impact resistance of fragment-bonded anterior teeth restored with Composite resin (Shofu) and resin-modified glass ionomer cement (RMGIC, Vitremer). Impact resistance was measured using an Impact Testing Machine, and data were analyzed with AutoCAD 2000 software, applying the Students t-test and ANOVA for statistical evaluation.Master Chart Observations that chart presented impact resistance and fracture surface area values for intact and fragment-bonded teeth. Values were recorded in joules and converted to kilojoules, while fracture surface areas were measured in mm and converted to m .Conclusion showing that the intact control group exhibited significantly higher impact resistance than both Composite resin and RMGIC groups. Further research is needed to optimize restorative materials for better clinical outcomes.
