Randomized Trial Comparing Accuracy of Metallic and Plastic Probes for Single-Unit Dental Implant Assessment

What this Trial Is About

This research aims to assess whether the type of probe usedplastic versus metallicaffects the accuracy of peri-implant probing in patients with single-unit dental implants. It compares the probing depth measured with the prosthesis in place to that recorded without the prosthesis. Additionally, the study explores how prosthetic design and implant position influence probing measurements and other clinical and radiographic outcomes. Participants are randomly assigned to two groups one using a metallic UNC-15 periodontal probe and the other using a plastic UNC-15 periodontal probe. Probing is conducted at six sites per implant, both with the prosthesis on and after its removal, using a standardized force. The study follows a parallel group design and includes patient-reported discomfort assessment using a visual analogue scale. During a single clinical visit, participants undergo peri-implant probing and have their probing depths recorded. Researchers evaluate the difference in probing depth with and without the prosthesis, patient discomfort during probing, and other clinical and radiographic parameters. The study follows international consensus guidelines for implant dentistry outcomes and is sponsored by the University of Barcelona, with completion expected in October 2026.
