Abstract
Background Personality factors might influence participants' satisfaction and the effects of dental management on daily living. Purpose This randomized controlled clinical trial aimed to assess the impacts of two types of implant-supported maxillary anterior crown restorations on daily living and participants' satisfaction, and its correlations with personality profiles. Materials and Methods One hundred and seventy participants (84 males and 86 females; mean age = 35 +/- 9 years) obtained maxillary anterior implant-supported crowns. They were allocated into two treatment groups (85 participants each: 43 females and 42 males). Group 1 was treated with titanium abutment-supported porcelain fused to metal (PFM) restorations. Group 2 was treated with zirconium abutment-supported ceramic restorations. A control group (85 participants each: 43 females and 42 males) that matched the treatment groups in gender and age was recruited. Precise clinical standards were followed to judge the clinical success of treatment. The NEO Five-Factor Inventory was used to evaluate participants' personality profiles. The dental impact on daily living questionnaire (DIDL) was used to evaluate restoration impacts on daily living and participants' satisfaction. Statistical analysis was carried out with probability of alpha = .05. Results Higher DIDL scores were reported after crown treatments (P < .001). Group 2 participants reported highest levels of satisfaction with appearance (P = .007). DIDL scores were significantly associated with neuroticism, extraversion, and openness scores (P < .05) before restoration, and, with neuroticism, extraversion, agreeableness, openness, and conscientiousness scores (P < .05) after restoration. Conclusion Implant-supported crown restorations in anterior maxillary region were associated with positive impacts on daily living and participants' satisfaction. Implant-supported ceramic crowns and abutments were accompanied with higher levels of satisfaction with appearance than implant-supported PFM crowns and titanium abutments. Certain personality and psychological features (neuroticism, extraversion, agreeableness, openness, and conscientiousness) might affect and predict dental satisfaction and impacts on daily living.
