Patient Satisfaction with Implant-Supported Monolithic and Partially Veneered Zirconia Restorations

Abstract

The digital workflow and the application of Computer-Aided Manufacturing (CAM) to prosthodontics present the clinician with the possibility of adopting new materials that confer several advantages. Especially in the case of zirconia, these innovations have profoundly changed daily practice. This paper compares the satisfaction and perception of patients who received implant-supported single crowns (SC) and fixed partial dentures (FPD) made from zirconia, either monolithic or partially veneered, after 3 years of follow-up; the success and survival rate of these restorations were also measured. Forty patients, who had been previously treated with implant-supported SC or FPD, either monolithic or partially veneered, and submitted to a yearly maintenance program, were recalled 3 years after their treatment and requested to complete an 8-question questionnaire regarding their perceptions of the treatment. Any mechanical or biological complication that had occurred from the time of delivery was also recorded. Patients that experienced ≥1 complication were less likely to be prone to repeat the treatment. The 3-year success rate was 92.6% for monolithic restoration and 92.3% for partially veneered restoration, while the survival rate was 100% for both restorations. The 3-year follow-up found that monolithic and partially veneered zirconia restorations are both well-accepted treatment options, and patients preferred the veneered restorations (0.76, p < 0.05 ) from an aesthetic point of view. According to our results, monolithic and veneered zirconia restorations are both reliable treatment options and are both equally accepted by patients.

The Application of Angulated Screw-Channels in Metal-Free, Implant-Supported Restorations: A Retrospective Survival Analysis

“…The present study reported on the success rate of screw-retained FPD employing ASC. At the 2 years follow-up, a success rate of 94% was observed; this is in line with what other studies reported on FPD not employing ASC [26][27][28], hinting that this retentive system does not reduce the efficacy of these kind of restorations.…”

Endocrowns Clinical Performance and Patient Satisfaction: A Randomized Clinical Trial of Three Monolithic Ceramic Restorations

“…39,40 Patients were less satisfied with shade and proximal contacts with Enamic and monolithic zirconia. Some studies showed less patient satisfaction with monolithic zirconia when compared to bi-layered zirconia restorations, 41 while other studies reported a high satisfaction with monolithic zirconia crowns. 33,42 Color match was rated excellent in other studies investigating Enamic partial restorations.…”

Satisfaction and attitudes of the student population about dental aesthetics

“…When planning orthodontic therapy, in addition to the specialist assessment of malocclusion, it is necessary to take into account the subjective needs, that is, the esthetic perception of the patient. Technological progress through the application of new materials and methods has enabled significant advances in prosthetic rehabilitation, which occupies a significant place in cosmetic dentistry aimed at achieving patient satisfaction with their smile (48)(49)(50). One should have in mind that prosthetic treatments are financially challenged, so the socio-economic status of the patient might influence the final therapy choice.…”
