CAD reconstruction using contralateral mirrored anterior teeth: a 3-dimensional metric and visual evaluation

Area of Science:

• Dental technology
• Biomedical engineering
• Computer-aided design (CAD)

Background:

• Accurate restoration of anterior teeth is crucial for aesthetics and function.
• Traditional CAD methods may lack personalized morphologic data for contralateral teeth.
• Developing efficient digital workflows for dental restorations is an ongoing challenge.

Purpose of the Study:

• To evaluate a novel computer-aided design concept for anterior teeth restorations.
• To assess the feasibility of using mirrored contralateral tooth morphology in CAD.
• To establish a digital workflow integrating contralateral tooth data for dental restorations.

Main Methods:

• Utilized a digital 3D tooth library for automatic mirroring, rotation, and translation of ipsilateral teeth.
• Integrated morphologic information from contralateral teeth into the CAD process.
• Evaluated reconstruction outcomes using 3D similarity measures, approximal/antagonistic relationship analysis, and expert visual ratings.

Main Results:

• Metric and visual evaluations confirmed the viability of the contralateral tooth mirroring concept.
• The digital mirroring approach provided a suitable base for anterior restoration design.
• Expert assessments supported the aesthetic and functional potential of the method.

Conclusions:

• Mirroring contralateral tooth morphology is a promising strategy for computer-aided design of anterior restorations.
• This digital approach enhances the personalization and accuracy of dental CAD.
• The study provides a foundation for advanced, morphology-driven digital dentistry workflows.
