Effect of Injection Guide Design on the Accuracy of Direct Composite Veneers: An In Vitro Study.

Key Points

• The aim is to evaluate how different injection guide designs affect the accuracy of direct composite veneers in esthetic dentistry.
• Conducted an in vitro study comparing various injection guide designs.
• Evaluated the morphologic accuracy of direct composite veneers produced using each guide type.
• Analyzed the technical sensitivity and efficiency of each method.
• Certain injection guides resulted in significantly more accurate veneers compared to others.
• Improved guide designs led to fewer technical errors during the application process.
• Findings suggest potential long-term benefits for the esthetic appearance of composite veneers.
