Periodontal Endoscopy for Mechanical Debridement in the Non-Surgical Management of Peri-Implantitis: A Narrative Review.

Background

The aim of the present narrative review is to synthesize the available scientific evidence on the effects of submarginal instrumentation with periodontal endoscopy and evaluate its' potential efficacy in terms of the non-surgical therapy of peri-implantitis.

Methods

The literature search was performed via electronic databases, including PubMed, Web of Science, Cochrane, and Scopus, and was supplemented by manual searching. A literature review was conducted addressing the following PICOS questions: (1) What is the efficacy of non-surgical submarginal instrumentation of the implant surface with the aid of a periodontal endoscope in patients with peri-implantitis? (2) What is the efficacy of non-surgical subgingival instrumentation performed with the aid of a periodontal endoscope compared with conventional subgingival instrumentation in patients with periodontitis, in terms of clinical parameters and patient-reported outcomes? Mechanical decontamination of the implant surface is crucial for resolving inflammation and arresting further bone loss. However, there is no consensus on the most effective treatment. Non-surgical therapy remains the initial intervention, focused on biofilm removal to control the disease, although with limited capability to achieve complete disease resolution as the presence of threads and the complex-structured implant surface hinder effective biofilm removal. This evokes the need for providing supporting technologies such as periodontal endoscopy, which enables direct visualization and precision, potentially enhancing the outcomes and reducing the necessity for surgical procedures and their associated risks. Within the limitations of this narrative review, periodontal endoscopy may offer a less tissue-invasive approach. Larger prospective studies and RCTs are needed to confirm these findings and guide clinicians in determining periodontal endoscopy's suitability based on specific case characteristics.
