Investigational drug(s) / intervention(s)

Metallic UNC-15 periodontal probePlastic UNC-15 periodontal probe

Metallic UNC-15 periodontal probe: Probing performed at six sites per implant with the prosthesis in place and after prosthesis removal, under standardized force (0.20 N).

Plastic UNC-15 periodontal probe: Probing performed at six sites per implant with the prosthesis in place and after prosthesis removal, under standardized force (0.20 N).

Study summary

Evaluate whether the type of probe (plastic vs. metallic) modifies the accuracy of peri-implant probing in single-unit implants, by comparing the probing depth recorded with the prosthesis in place versus without the prosthesis (ΔPD, mm). Secondarily, explore the influence of prosthetic design and implant position on probing values and on other clinical and radiographic parameters.

Inclusion Criteria: * Adults (≥18 years) * Presence of at least one single-unit bone-level implant rehabilitated with a screw-retained prosthesis directly connected to the implant (no intermediate abutment) * Implant in function for at least 1 year after prosthetic loading * No pathological bone loss on periapical radiograph (distance from the most coronal rough surface of the implant to the bone crest \< 3 mm) * Ability to understand and sign informed consent * Peri-implant health or mucositis, defined according to the 2017 World Workshop criteria: * Health: no clinical signs of inflammation, lack of profuse (line or drop) bleeding on probing, no increase in probing depth compared to previous records, and no progressive bone loss beyond initial remodeling (\<2 mm). In the absence of previous radiographs, radiographic bone level \<3 mm without bleeding and/or suppuration on probing. * Mucositis: presence of bleeding and/or suppuration on probing, no increase in probing depth compared to previous records, and no bone loss beyond initial remodeling (\<2 mm). In the absence of previous radiographs, radiographic bone level \<3 mm with bleeding and/or suppuration on probing. Exclusion Criteria: * Cement-retained restorations or prostheses that cannot be removed * Systemic antibiotic or anti-inflammatory treatment within the previous 3 months * Pregnancy or lactation * Peri-implant treatment within the previous 3 months * Participation in another clinical trial within the last 30 days

Primary outcome measure(s)

  • Difference in probing depth with vs. without prosthesis (ΔPS, mm) — Baseline (single clinical visit)
    Difference in peri-implant probing depth (ΔPS) between plastic and metallic probes, measured by a single calibrated examiner at six sites per implant using a standardized probing force (20-25 g). Unit of Measure: millimeters (mm) This primary outcome was defined following the mandatory outcome domains recommended by the international consensus on Implant Dentistry Core Outcome Set and Measurement (ID-COSM), published in the Journal of Clinical Periodontology in 2023.
