An Innovative 3D Printed Tooth Reduction Guide for Precise Dental Ceramic Veneers

Area of Science:

• Dentistry
• Dental Materials
• Biomaterials

Background:

• Accurate tooth reduction is crucial for successful ceramic restorations.
• Traditional silicone guides offer limited access for preparation evaluation.
• Minimally invasive dentistry preserves tooth structure.

Observation:

• A novel computer-aided design (CAD) additive computer-aided manufacturing (a-CAM) tooth reduction guide was developed.
• The guide features innovative vertical and horizontal channels for preparation and evaluation.
• A periodontal probe was used through the channels for assessment.

Findings:

• The novel guide facilitated uniform tooth reduction, preventing overpreparation.
• Minimally invasive preparations were achieved for laminate veneer restorations.
• The design allowed for comprehensive evaluation in all directions, offering greater flexibility than silicone guides.

Implications:

• This 3D printed guide is a valuable tool for achieving optimal dental restoration outcomes with minimal tooth reduction.
• The design advances dental restoration technology by improving preparation accuracy and assessment.
• Further research is needed to compare this guide with other 3D printed options regarding reduction accuracy and preparation time.
