Orthodontic treatment in patients with periodontitis - anarrative literature review.

Abstract

Patients with periodontitis often require an inter-disciplinary approach, including orthodontic treatment, for effective rehabilitation of masticatory function, aesthetics and quality of life. The aim of this narrative review was to comprehensively discuss literature focusing on the biology, indications and inter-disciplinary connections related to the orthodontic approach in patients with periodontitis and to present clinical concepts in accordance with valid guidelines. The outcomes of the experimental studies indicate that orthodontic tooth movement (OTM) can be performed safely for teeth with reduced periodontium, provided infection and inflammation are controlled. Orthodontic treatment can correct pathological tooth migration, is not associated with deterioration of clinical periodontal parameters and improves aesthetics. Intrusion is safe when performed with light forces and under a strict oral hygiene regimen. Teeth can be moved either towards or away from the intrabony defect previously subjected to regenerative procedures, and research suggests that OTM has the potential to enhance bone formation after regenerative therapy. The data on orthodontic movement of teeth with furcation involvement are very scarce. The improvement in furcation involvement following either combined periodontal and orthodontic treatment was only documented in animal model studies. Due to bone and tooth loss, special consideration should be given to orthodontic treatment mechanics. © 2023 Australian Dental Association.
