Access to Probing and Peri-implant Diseases

Condition(s) studied

Investigational drug(s) / intervention(s)

Peri-implant probing: This is a non-interventional, observational cross-sectional multicenter study. No therapeutic, surgical, or pharmacological interventions are performed as part of the study. All procedures correspond to standard clinical practice and include: Peri-implant clinical examination, consisting of probing depth measurements at six sites per implant using a manual periodontal probe. When access is limited, a flexible plastic probe may be used. Assessment of probing accessibility, categorized according to the angulation and feasibility of probe insertion without prosthesis removal (possible, limited, or impossible). Recording of routine clinical parameters, including plaque presence, bleeding on probing, suppuration, and patient-reported hygiene practices. Radiographic assessment, consisting of standardized periapical radiographs obtained using a parallel technique for the evaluation of marginal bone levels. No modifications to the patients' treatment, prosthetic design, or maintenance protocol

Study summary

This multicenter cross-sectional study aims to evaluate the association between access to peri-implant probing and radiographic peri-implant bone loss. Although probing is the primary diagnostic tool for peri-implant diseases, prosthetic design may limit access, potentially affecting diagnosis and disease progression. The study will include patients with dental implants in function for at least three years and will assess clinical, radiographic, and prosthetic variables.

Eligibility

Primary outcome measure(s)

• Association between probing access and peri-implant radiographic bone loss — Baseline (cross-sectional assessment)
  Evaluation of whether limited or impossible probing access is associated with increased radiographic bone loss (measured in mm from implant platform to bone level).
