Patient satisfaction of vita enamic versus lithium disilcate hybrid abutment crowns in implants placed in the anterior zone

Abstract

Aim: This study was performed to evaluate the use of vita enamic versus lithium disilicate hybrid abutment crowns on the patient satisfaction. emax was found to be a stiff material when used with implants. This causes a remarkable stress concentration in the crestal bone that is a primary factor in bone loss resulting in failed esthetic restoration in the anterior esthetic zone.with subsequent patient dissatisfaction. Methodology: forty two patients who needed a single implant restoration in the esthetic zone were included in this study. 42 patients completed screening, twelve-month follow-up visits. At the screening visit, the patients were randomly allocated into two groups: vita enamic hybrid abutments (A) Group, and lithium disilicate hybrid abutments (B) Group. Patients Satisfaction was assessed by visual analogue scale (VAS). Results: All implants were successfully osseo-integrated with a 100% survival rate over one year. Patient satisfaction for vita enamic is comparable to lithium disilicate. Conclusions: Both Lithium Disilicate and Vita Enamic hybrid abutment crowns reported high scores of patient satisfaction throughout the follow up period.
