Abstract:

Aim: This study compares the time for making prosthetic structures with individual abutments with standard impressions and fully CAD-CAM abutments. The null hypothesis is that there is no difference between the two groups studied.
Materials and methods: Thirty implants from the Neo system (AlfaBio, Tel Aviv, Israel) placed on patients aged 30 to 50 years without concomitant diseases were examined. Two protocols were used for the abutment and prosthetic construction: fully digital CAD/CAM and standard.
Results: The total time for fully CAD-CAM abutments and crown is statistically significantly less than the time to produce individual abutments with standard impression and prosthetic construction.
Conclusion: The ability to design and manufacture customized abutments with precise anatomical shapes individually according to the clinical situation can reduce stress during chewing and help improve successful long-term aesthetic and functional outcomes.

Keywords: digital healing abutment; individual healing abutment; CAD-CAM construction
