Consequence of injectable platelets rich fibrin versus microosteopeforation on root resorption during orthodontic intrusion of incisor teeth
This study aims to investigate the effectiveness of low-level laser in reducing the resorption of the roots of the upper incisors. Participants will be recruited from patients who will attend the Department of Orthodontics and Dentofacial Orthopaedics at Damascus University. The study sample will consist of 30 patients with a deep bite who will be randomly distributed equally into two groups, 15 patients in each group, average age: 22.37±3.38 years. Mini-implants will apply between the roots of the maxillary central and lateral incisor at both sides with a loading force of 40 g on each end by using a nickel-titanium spring extending from the head of the mini-implants to a wire welded to it with two hooks. A low-level laser (Ga-Al-As) will be used with 808 nm wavelength in continuous mode, 250 milli-Watt power output, 4 Joules/point energy density, 16 s per point in the experimental group. It will be applied on the day of intrusion, then on days 3,7, and 14 of the first month, and then every 15 days starting from the second month until the end of the intrusion. In addition to adjusting the force gauge every 4 weeks until the end of the intrusion stage and reaching normal coverage will be activated every 4 weeks in both groups until normal overbite was reached.
The present study will be directed to evaluate the effect of low-level laser therapy on root resorption during orthodontic intrusion of upper incisors.
Rationale: Class II Division 1 malocclusion is characterized by upper anterior teeth protrusion resulting in upper lip protrusion and convex facial profile, which are considered esthetically unfavorable. Treatment of class II malocclusion due to maxillary protrusion can be done with bilateral maxillary first premolar extraction followed by en-masse retraction of upper anterior teeth using mini implants placed between maxillary 2nd premolar & 1st molar. Treatment of class II malocclusion due to maxillary protrusion without premolar extraction frequently requires distalization of maxillary molars into Class I molar relation by means of extra-oral or intraoral forces. Absolute skeletal anchorage, available 24 hours a day is an alternative method for molar distalization. Zygomatic miniplates fixed at a distance from the root apices, allows distalization of entire dentition as there is no interference between the fixation device and roots of the teeth. Aims and Objectives: To quantify root resorption seen with bilateral extraction of maxillary first premolars (followed by en - masse retraction of anterior teeth) vs full arch distalization with zygomatic miniplates in Class II Division I malocclusion. Method of study: Patients will be allocated randomly to 2 groups-G1 and G2. Patients in G1 will undergo bilateral maxillary 1st premolar extraction before bonding followed by leveling & alignment. Maxillary arch will be stabilized with the help of 0.019"×0.025" stainless steel wire. Hooks will be soldered on archwire used for stabilizing dentition. Mini implants will be placed under local anaesthesia between maxillary 2nd premolar & 1st molar. Ni-Ti closed coil spring will be used to apply a force for en masse retraction of maxillary anterior teeth . In G2, treatment will be initiated by bonding 0.022" slot MBT preadjusted edgewise appliance. Maxillary arch will be stabilized with the help of 0.019"×0.025" stainless steel wire. Zygomatic miniplates will be placed bilaterally. Hooks will be soldered on archwire used for stabilizing dentition. Ni-Ti closed coil spring will be used to apply a force .
The goal of this study is to compare the three dimensional root resorption after extraction space closure in two groups: two step retraction and en masse retraction. Th main aim of this study is to conclude which method is less damaging to the roots. Participants will be divided into two groups: 1. En masse retraction (experimental) 2. Two step retraction (control) Pre retraction and post retraction CBCT scans will be compared for both groups.
