Details and patient eligibility

About

The main purpose is to compare overall alignment time (OAT) in days in alleviating mandibular incisors crowding between control group and MOPs group.Furthermore, to investigate the presence of volumetric root resorption from CBCT, gingival recession and formation of black triangle post lower labial segment alignment between micro-osteoperforations group and control group.

Full description

Prolonged treatment time in orthodontics is an undesirable side effect for both the patient and clinician. Usually, an average course of comprehensive orthodontic treatment with fixed appliances requires less than 2 years to complete (19.9 months). This prolonged treatment time may cause adverse effects such as root resorption, gingival recession, caries & enamel demineralization. Micro-osteoperforations is safe, minimally invasive technique which perforations are performed through the gum tissues, penetrating the bone without the need to raise a flap.Control group will not received any MOP and will receive standard orthodontic treatment.

Enrollment: 19 patients

Micro-osteoperforations

Experimental group

Description:

Lower arch, 2 MOPs vertically at interdental area bilaterally mesial to lower 6's ; mesial to lower 1st premolar; mesial to lower 2's and between the lower 1's..The start date of lower labial segment alignment (T1) was recorded after insertion of the lower 0.014'' NiTi archwire. Participants were reviewed every 6 weeks and repeated MOPs were performed for the experimental group until the completion of lower labial segment alignment (LLS), which is when the Little's irregularity index scores one, indicating a minimum irregularity of ≤ 2 mm contact point displacement, based on the contact point displacements of the mandibular anterior segment, from canine to canine.
