Summary
Cerec Connect software more accurately simulated maximum intercuspal contacts compared to inLab software in an in-vitro study. This finding is crucial for digital dentistry workflows and prosthetic restorations.
Area of Science:
- Digital Dentistry
- Dental Technology
- Occlusion Simulation
Background:
- Accurate simulation of maximum intercuspal contacts is vital for successful prosthetic restorations.
- Digital impression systems offer potential for improved accuracy in capturing occlusal relationships.
Purpose of the Study:
- To evaluate and compare the accuracy of inLab and Cerec Connect software in simulating maximum intercuspal contacts.
- To assess the virtual simulation against real occlusal contacts on gypsum casts.
Main Methods:
- Ten pairs of gypsum casts were analyzed in maximum intercuspal position.
- Digital impressions were captured using inLab and Cerec Connect software.
- Virtual occlusal contacts were compared to marked contacts on gypsum casts using image processing.
Main Results:
- Cerec Connect achieved a median accuracy of 41.6% in simulating contacts.
- InLab software achieved a median accuracy of 31.9%.
- Statistically significant differences were found, with greater deviations on the contra-lateral side.
Conclusions:
- Cerec Connect demonstrated higher precision in virtually simulating real occlusal contacts compared to inLab.
- The findings suggest Cerec Connect may be more suitable for full-arch dentition scanning for occlusal analysis.
