Abstract

Objective: Hard tissue outcomes after implant placement have been well documented. However, there is scarce evidence on immediate soft tissue and patient-centered outcomes. The aim of this prospective study is to quantify post-implant placement edema and to correlate it with oral health-related quality of life. Methods: Patients undergoing a standardized two-stage implant placement at a single tooth-bound site were recruited (n=26; 54.13.3 years, 14 males). Soft tissue edema was recorded by using intraoral scans immediately pre- (PS) and post-operatively (IP), at 2 (2D), 7 (7D) and 14 days (14D) and 2 months (2M). After scan registration, ridge width, maximum height, and volume changes from IP were recorded. OHIP-14 and VAS for pain and swelling were recorded at preop and follow-up visits. Results: Ridge width (1.90.04mm), height (1.4 0.02 mm) and volume (37.80.8%) peaked on 2D. Ridge width reached PS levels by 14D (p=0.44). Height increases from IP to 2D and 7D were the highest compared to all other time point increases (p<0.0001). OHIP-14 and VAS for pain and for swelling exhibited a similar trajectory, peaking at 2D and reaching PS levels by 7D (pain: PS/7D p=0.07; OHIP-14: PS/7D p=0.28) and 14D (swelling: PS/14D p=0.18). There were no statistically significant correlations between edema, OHIP-14 and VAS measurements. Conclusion: Following implant placement, soft tissue changes show a maximal response at 2 days and patients experience the most significant pain and swelling and the worst oral health-related quality of life at the same time point. However, clinically measured and patient-reported outcomes were not correlated.
