Crowding of Anterior Maxillary Teeth
Conditions
Brief summary
Mandibular incisor crowding is a frequent issue that prompts many adults to seek orthodontic treatment. The treatment may enhance patients' quality of life, facilitate dental plaque control, and improve the quality of periodontal tissue. However, this treatment is accompanied by several side effects, including resorption of the apical portion of the teeth. Platelet-rich concentrates, such as injectable platelet-rich fibrin, have been shown to have positive effects on both soft- and hard-tissue healing. They may serve as a beneficial self-derived material to prevent this complication.
Detailed description
In recent years, increasing attention has been directed toward biologically driven approaches to modulate tissue responses during orthodontic treatment and minimize adverse effects, such as root resorption. Platelet-rich fibrin (PRF), a second-generation autologous platelet concentrate, has emerged as a promising biomaterial due to its high concentration of platelets, leukocytes, and a fibrin matrix that allows gradual release of multiple growth factors, including platelet-derived growth factor (PDGF), transforming growth factor-β (TGF-β), vascular endothelial growth factor (VEGF), and insulin-like growth factor (IGF). However, in 2014, injectable platelet-rich fibrin (I-PRF), which is similar to PRF, was introduced in France by Choukroun, using non-glass tubes and adjusting the centrifugal force. Just like traditional PRF, i-PRF contains high levels of growth factors, stem cells, leukocytes, and cytokines. These growth factors play a crucial role in angiogenesis, tissue regeneration, modulation of inflammation, and bone remodeling, all of which are central processes in orthodontic tooth movement and periodontal healing.
Interventions
I-PRF will be injected in 4 sessions at 28-day intervals. The injection will administered submucosally in the buccal region of the lower incisors, using 2 ml of i-PRF per session (0.5 ml per incisor). Orthodontic wires will be sequenced until they reach 0.019×0.025-inch stainless steel.
Saline serum will be injected in 4 sessions at 28-day intervals. The injection will be administered submucosally in the buccal region of the lower incisors, using 2 ml of i-PRF per session (0.5 ml per incisor). Orthodontic wires will be sequenced until they reach 0.019×0.025-inch stainless steel.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in root length | First assessment time: one day before the commencement of treatment. Second assessment time: within one week following the leveling and alignment stage (The stage is expected to finish within 4 to six months after the beginning of treatment) | Root resorption (i.e., change in root length) will be measured by calculating the difference in the full linear length of each incisor (incisal edge to the apex) between two assessment times (in millimeters) using CBCT images. |
