Overview
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.
Description
Peri-implantitis is a plaque-induced inflammatory condition characterized by inflammation of peri-implant tissues and progressive bone loss. Probing is essential for diagnosis; however, prosthetic design may hinder or prevent proper probing access, potentially compromising diagnostic accuracy.
Despite its clinical relevance, no studies have directly evaluated whether limited access to probing is associated with peri-implant bone loss. This study aims to address this gap.
This is a multicenter cross-sectional observational study conducted in nine private clinics in Spain. A total of 281 patients will be included. Clinical and radiographic data will be collected, including probing accessibility, probing depth, plaque index, bleeding on probing, suppuration, prosthetic design, hygiene accessibility, and radiographic bone levels.
Statistical analysis will evaluate associations between probing access and peri-implant bone loss at both patient and implant levels.
