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.
The aim of this review is to summarize biological products -bone replacement materials and techniques for regenerative endodontic therapy. Bone grafting is a dynamic phenomenon. Successful transplantation involves graft placement, healing, incorporation, revascularization, and the formation of the desired amount of new bone.The techniques for regenerative endodontic therapy are described: аpexification and apexogenesis; treatment of vital inflamed dental pulp while maintaining its vitality; treatment of chronic periapical periodontitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
