Effect of Injectable Platelet-rich Fibrin on the En Masse Retraction of Maxillary Anterior Teeth
Effect of Injectable Platelet-rich Fibrin (i-PRF) on the Rate of Orthodontic En Masse Retraction of Maxillary Anterior Teeth: A Randomized Controlled Clinical Trial
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
Trial will be carried on 2 groups, each involve 13 participants with a total of 26 participants.
- Subject examination to ensure he/she meets the eligibility criteria of the research.
- Leveling and alignment using fixed orthodontic appliance.
- Upper first premolars extraction as a part of the orthodontic treatment planning.
- With the starting of en masse retraction, injection of the (i-prf) obtained from venous sample palatally and distally to the anterior teeth in the intervention group, and sham injection in the control group. The injection in both groups will be done just before retraction, 21 and 42 days after beginning of retraction Rate of en masse retraction will be calculated for patients in both groups at the monthly basis for for months after starting en masse retraction, data will be analyzed statistically.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: intervention group
Intervention group subjects will receive injectable platelet rich fibrin (i-prf) . The (i-prf) will be injected in the periodontal ligament of maxillary anterior teeth during en masse retraction.The injection sites will be the sites of bone compression to target the surfaces of the bone where osteoclastogenesis and bone resorption occurs during en masse retraction. Considering that the obtained (i-prf) after centrifuging would be 4 ml, 1 ml will be injected intraligamentally distal to the right and left canines, and 0.5 ml will be injected intraligamentally palatal to each incisor. The study group will receive i-PRF intraligamentally in the periodontal ligament space of the maxillary six anterior teeth three times as follow, just before anterior teeth retraction, and after 21 days of the retraction, and after 42 days of the retraction. Before each time of injection, an anesthetic solution will be administered for pain control. |
I-prf is a second-generation PRP where autologous platelets and leukocytes are present in a complex fibrin matrix and can be obtained from blood using low-speed centrifugation without adding anticoagulants.
|
Sham Comparator: control group
Subjects in the control group will only receive sham (placebo) injection three successive times with and interval of 21days between each injection, similar to the timepoints of (i-prf) injection in the intervention group.
Also the sites of injection will be similar to the sites of injection of the intervention group; 1 ml of the placebo agent will be injected intraligamentally distal to the right and left canines, and 0.5 ml will be injected intraligamentally palatal to each incisor.
An anesthetic solution will be administered for pain control before the administration of the sham injections.

Measure Description |
Time Frame |
---|---|---|
Rate of En masse retraction
Time Frame: 4 months
|
Alginate impression will be taken for each participant to obtain a plaster model obtained at five time points: before incisor retraction (T0), after one month (T1), after two months (T2), after three months(T3), and after four months (T4) of retraction.
The models will be coded with numbers assigned to the participants, and will be sent to an assessor not participating in the research.
In both groups, the amount of space closure will be calculated by a digital caliper in millimeters for each time point (T) and averaged for right and left sides.

Associated Pain
Time Frame: 4 months
|
Pain will be assessed using a visual analogue scale questionnaire that will be completed by the patient starting from the day following i-prf injection in the intervention group or the sham injection in the control group, the questionnaire will be repeated every month until the fourth month
