Randomized Clinical Trial on the Effect of Micro-osteoperforations (MOPs) During Intrusion of Flared Upper Anterior Teeth in Stage IV Periodontitis Patients
Micro-osteoperforations (MOPs) cause cortical bone injuries and consequently increase the expression of inflammatory mediators, allowing for increased bone and periodontal ligament remodeling associated with orthodontic movement. It remains unclear the effect of orthodontic intrusion combined with MOPs application on teeth with reduced periodontium. The general objective will be to determine the efficacy of MOPs during orthodontic tooth movement (OTM) in terms of periodontal and orthodontic outcomes in stage IV periodontitis patients, case type 2 with pathological tooth migration (PTM), characterized the presence of at least one flared tooth of the upper-anterior sextant with an intrabony defect (intrabony component \<5mm)
⁃ 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.
