Zirconia Abutment Supporting All Ceramic Crowns in the Esthetic Zone: Interim Results of a Prospective Study.
AIM: This prospective study evaluated peri-implant tissues around all-ceramic crowns fabricated using CAD/CAM technology.
MATERIAL AND METHODS: Twenty-five patients received pre-fabricated zirconia implant abutments with CAD/CAM zirconia copings in the esthetic zone. Implants were evaluated at baseline, and at 3 and 6 months in function.
RESULTS: Radiographic analyzes showed stable bone crest around the implants. Esthetics were more favorable as time lapsed (p > 0.05). Bleeding Index was constant in all time intervals. Plaque index reduced from 3 to 6 months.
CONCLUSION: The all-ceramic CAD/CAM crowns were clinically, radiographically and esthetically stable during the study period.
