Abstract

PURPOSE
This study was designed to measure patient satisfaction and oral health-related quality of life and to assess an association between patients' satisfaction and oral health-related quality of life after implant surgery by using structural equation modeling.
MATERIALS AND METHODS
A total of 257 participants who visited 6 dental clinics located in Daegu city for the purpose of implant treatment participated in this study. Six months after completion of implant surgery, the patients' satisfaction and oral health-related quality of life were surveyed. The effect of factors associated with patients' satisfaction such as functions and aesthetics, maintenance and cost on oral health-related quality of life after implant surgery was analyzed using AMOS 4.0.
RESULTS
Oral health-related quality of life was improved in all dimensions of OHIP-14 after implant surgery. Functions and aesthetics as well as maintenance had a significant effect on oral health-related quality of life (P<.05), while cost was not a critical factor influencing oral health-related quality of life.
CONCLUSION
High satisfaction with functional aspects and maintenance aspects significantly affected good quality of life. The result of this study supported the fact that education and management for patients after implant therapy were positively related to good quality of life based on a theoretical model.
