Maintenance and repair requirements of anterior zone aesthetic restorations, investigation of complications and evaluation of patients' quality of life

Aim: To evaluate the clinical success of anterior zirconium-supported crowns and bridges, complications and the effect of existing prostheses on patients' quality of life in the last five years in the Department of Prosthodontics, Faculty of Dentistry, Eskişehir Osmangazi University. Materials and Methods: Patients who underwent zirconium-supported restorations between January 2018 and January 2023 at the Department of Prosthodontics, Faculty of Dentistry, Eskişehir Osmangazi University, were included. 108 patients participated in the study. In addition to the socio-demographic information obtained from the patients, the presence of complications was evaluated based on the modified USPHS clinical evaluation criteria. Pink and white aesthetic results were analyzed with PES-WES analysis and the effect of the current situation on the quality of life of the patients at the end of the entire clinical follow-up was evaluated with the OHIP-14 questionnaire. Results: Of the participating patients, 71 were female and 37 were male. The frequency of smoking, acidic drinks and tea and coffee consumption were analyzed. It was observed that the higher the consumption of tea and coffee, the more clinically acceptable marginal maladjustment occurred. A weak negative correlation was established between marginal adaptation, anatomical form, secondary caries, tooth integrity, restoration integrity and post-operative sensitivity parameters and PES and WES values. There was a weak negative correlation between the duration of use and the complication parameters secondary caries, tooth integrity and restoration integrity. As a result of the comparison of OHIP-14 and complication parameters, a weak positive relationship was established between physical pain-marginal adaptation, psychological inadequacy-anatomical form. It was observed that the quality of life of the patients increased as the number of members increased. The presence of postoperative tenderness and incompatibilities in the whole resrotation increased the overall OHIP value and thus decreased the overall quality of life. Conclusion: According to the findings, the most common complication was post operative tenderness followed by fracture/cracking of the restoration structure. The presence of existing complications decreased the quality of life of the patients. In order to increase the quality of life and the duration of use of the patients, clinical follow-up periods should be more regular and at shorter intervals.
