Comparison of Fracture Resistance of Conventional Composite Veneers with Novel Veneer Preparation Design- In Vitro Study

The patient's primary concern or need for good and pleasing esthetics of anterior teeth has increased. With the progression in the restorative field, multiple treatment options exist for patients’ complaints. Composite veneering is one of the suitable and an appropriate treatment option with classic properties that is a good mechanical property, bend strength, abrasion resistance, and longevity of direct anterior restoration. Objectives: To compare fracture resistance of conventional and novel veneer preparation (a modified form of feather edge preparation) design in the indirect composite veneer method. Methods: In Vitro, a comparative study was conducted at the Department of Operative Dentistry and Endodontics Dr. Ishrat Ul Ebad Khan Institute of Oral Health Sciences, Dow University of Health Sciences Karachi time duration of six months by using a non-probability consecutive sampling technique. Data analysis was performed using SPSS version 26.0. The independent sample T-test was applied to compare the fracture resistance between the two procedures. Results: In terms of fracture load performance, the Conventional Veneer group had an average fracture load of 309.7 ± 126.3 N, compared to 335.5 ± 136.14 N in the Novel Veneer group. Although the Novel Veneer group showed a higher mean fracture load, this difference was statistically significant (p=0.005). Conclusion: It was concluded that increasing fracture resistance of the prepared materials with new preparation designs trends in the present study, however, the obtained data were statistically significant (p-value 0.005).
