EVALUATION OF A NEW ULTRASOUND INSERT IN GUIDED TISSUE REGENERATION (GTR): RETROSPECTIVE STUDY

After completion of the initial periodontal therapy (consisting of causal therapy and non-surgical mechanical therapy) the patient should be re-evaluated after some time in order to verify the achievement of the objectives: reduction in probing depth (PPD), increase in clinical attack level (CAL) and reduction in bleeding on probing (BOP).

Despite the successful outcome of the initial therapy, it is frequent to observe the presence of intrabony defects as an inevitable sequelae of periodontal disease during the re-evaluation phase: this represents a site-specific risk factor for the progression of periodontitis since the sites associated with these defects constitute ecological niches within which the reformation of a pathogenic biofilm will be more likely to favour a re-infection process.

Guided Tissue Regeneration (GTR) techniques address the treatment of these defects and are based on the principle of selective cellular exclusion: after debridement of the intraosseous lesion and treatment of the root surface, which must be carefully decontaminated by the bacterial biofilm, the defect is covered with a barrier membrane (possibly associated with a biomaterial grafted within the defect itself) in order to allow access and proliferation to the only cells capable of reconstructing the periodontal attack apparatus in its entirety.
