Esthetics Clinical Trial
Official title:
Comparison of the Short-term Clinical Efficacy of Angulated Screw-retained and Cemented Single Implant Crowns in Esthetic Region: A Randomized Controlled Clinical Trial
Objective: To compare the clinical efficacy of angulated screw-retained and cemented single
implant crowns(SIC) in esthetic region.
Methods/Design: The study was a prospective, single center, randomized controlled clinical
trial. Patients with the needs of single tooth restoration in esthetics region were recruited
from Oct. 2018 to Aug. 2019. Sixty patients were enrolled in the present study and they were
randomly assigned into two groups: angulated screw-retained group(AG, 30 patients) and
cemented group (CG,30 patients). Clinical and radiological evaluations were performed on the
day of final crowns delivery and 12 months later. Implant survival rate, marginal bone
loss(MBL), pro-inflammatory cytokinesin peri-implant crevicular fluid (PICF)(TNF-α, IL-6),
mechanical complications, peri-implant conditions(mPI, PD, BOP%), pink esthetics score/white
esthetics score (PES/ WES) and patients satisfaction were assessed.
