Effect of MOPs During Orthodontic Movement in Periodontitis Patients

This is a comparative 2-arm parallel single-blinded randomized controlled clinical trial, with allocation ratio of 1:1, aimed to test an intervention (the use of MOPs) on CAL changes 12 months after placing orthodontic appliances. The control intervention will be the same treatment without the bone traumatic intervention.

Sample: Patients with stage IV periodontitis case type 2 characterized with PTM characterized the presence of at least one flared tooth of the upper-anterior sextant with an intrabony defect (intrabony component <5mm) attending the Post-graduate Program of Periodontology and the Post-graduate Program of Orthodontics of the Faculty of Dentistry at the Complutense University of Madrid (UCM).

Inclusion criteria

Patients will be included if agreeing to undertake combined periodontal and orthodontic therapy following the clinical practice guideline of stage IV periodontitis patients, and fulfilling the following criteria:

• adult patients older than 18-year-old;
• systemically healthy (see exclusion criteria);
• diagnosed as stage IV (Papapanou et al., 2018) case-type 2 (Herrera et al. 2022) periodontitis;
• the presence of at least one flared tooth of the upper-anterior sextant with an intrabony defect (intrabonny component <5mm) (experimental teeth);
• in need of orthodontic therapy.

Exclusion criteria

• systemic diseases (diabetes mellitus, obesity, cardiovascular diseases);
• any medication that could affect the level of inflammation, (such as chronic antibiotics, phenytoin, cyclosporin, anti-inflammatory drugs, systemic corticosteroids, or calcium channel blockers);
• pregnant or lactating woman;
• inability to respond questions or to attend follow-up visits;
• extreme skeletal malocclusions requiring orthognathic surgery;
• patients smoking more than 10 cigarettes/day; and
• the presence of PD greater or equal to 5mm with BOP after step 3 of periodontal therapy
