Resin-bonded fixed dental prosthesis versus implant-supported single crowns in the anterior region.

Background: Different treatment options exist for replacement of an anterior tooth, and as implant-supported single crowns (ISSC) and resin-bonded fixed dental prosthesis (RBFDPs) both are widespread treatment options, it is of clinical relevance to know which treatment modality can be considered superior.

Purpose: The purpose of this comparative study was to evaluate the 3- and 5-year survival and failure rate of tooth-supported resin-bonded fixed dental prosthesis compared to implant-supported single crowns. The null hypothesis was that there was no significant difference in survival rate, occurrence of complications or patient-reported outcome between RBFDPs and ISSCs.

Digital versus conventional prosthetic workflow for dental students providing implant-supported single crowns: A randomized crossover study.

Statement Of Problem: Digital scanning has become popular and has been reported to be more comfortable for patients and equally or more accurate than conventional impression techniques. However, clinical evidence to support the advantages of digital scanning is sparse.

Purpose: The purpose of this randomized crossover study was to examine and compare the patient and provider perceptions of digital scanning and conventional impression making for implant-supported single crowns (ISSCs) provided by dental students under supervision.
