Brief summary

The present pre-post quasi-experimental study assessed changes in peri-implant disease perception and oral health-related quality of life following non-surgical peri-implant therapy. Using validated psychometric tools, including the Brief Illness Perception Questionnaire (Brief-IPQ) and the Oral Health Impact Profile-14 (OHIP-14), the study evaluates patients at baseline and three months after therapy. The study builds upon prior cross-sectional findings highlighting the low perception of peri-implant diseases and aims to determine whether non-surgical treatment improves patients' psychological awareness and perceived impact of their condition.

Interventions

PROCEDURENon-surgical peri-implant therapy

Standardized non-surgical therapy consisting of mechanical debridement of peri-implant sites using ultrasonic instruments, combined with personalized oral hygiene instruction. The intervention is delivered in a single session. No adjunctive antimicrobials are used. Follow-up is scheduled 3 months after therapy for clinical and psychometric re-evaluation.
