View on ClinicalTrials.gov →
Summary
This research is being done to evaluate the clinical, technical, biological, and aesthetic results of two different fabrication methods (additive and subtractive) for creating implant-supported fixed dental prostheses (iFDPs). Patients will receive an iFDP, meaning an implant-supported crown, according to regular treatment protocols. The fabrication method used to create the implant-supported crown will be decided in a randomised way. Clinical and radiological examinations will be performed prior to and when receiving the implant-supported crown and during a follow-up period of 3 years. Furthermore, technician- and patient-reported outcomes will be evaluated used questionnaires.
