Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Randomized clinical trial with two parallel groups. Eligible patients will be randomized (1:1 ratio) to one of two parallel treatment groups:

Group 1 (Metal probe): Peri-implant probing performed with a UNC-15 metallic periodontal probe (HuFriedy PCPUNC156).

Group 2 (Plastic probe): Peri-implant probing performed with a UNC-15 plastic periodontal probe (HuFriedy PCVO12PT).

Primary objective:

To 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 (ΔPS, mm).

Secondary objectives:

To explore the influence of prosthetic design (e.g., emergence profile, crown contour) and implant position on probing depth values and other clinical/radiographic parameters.

To evaluate patient-reported discomfort during peri-implant probing, recorded using a 100-mm visual analogue scale (VAS).

The study was designed in accordance with the international consensus on Implant Dentistry Core Outcome Set and Measurement (ID-COSM), published in the Journal of Clinical Periodontology in 2023. The protocol includes all applicable mandatory outcome domains recommended by this consensus for implant dentistry clinical trials.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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
