Evaluation of Periodontal Distractor in Acceleration of Canine Retraction

Start date: July 1, 2022
Phase: N/A
Study type: Interventional

evaluate the effect of periodontal distractor with and without interseptal bone cuts on the displacement of the maxillary canines, to assess the effect of two approaches on the pain intensity and on the pulp vitality of the retracted canines.

NCT ID: NCT05811728 Completed - Clinical trials for Orthodontic Tooth Movement

Three-dimensional Assessment of the Bone Changes Accompanying Laser-assisted Orthodontic Tooth Movement

Start date: February 25, 2023
Phase: N/A
Study type: Interventional

Aim of the present study is to evaluate the effect of low-level laser therapy on bone quality and quantity with orthodontic tooth movement.

NCT ID: NCT05782088 Completed - Clinical trials for Orthodontic Tooth Movement

Single Versus Repeated Piezocision-assisted Orthodontic Tooth Movement

Start date: January 1, 2023
Phase: N/A
Study type: Interventional

The primary aim of the study is to evaluate the effect of single and repeated piezocisions on the rate of orthodontic tooth movement. Secondary aims are to evaluate the effect of both protocols on molar anchorage loss, as well as on canine root resorption.

NCT ID: NCT05780788 Recruiting - Canine Retraction Clinical Trials

Characterizing Orthodontic Tooth Movement With Photographic Scans

Start date: December 31, 2020
Phase: N/A
Study type: Interventional

Characterizing orthodontic tooth movements in real time by using photographic scans to monitor teeth movement. The photographic scans will also be compared to 3D model scans. Canine retraction over the course of 1 orthodontic visit will be measured.

NCT ID: NCT05727124 Active, not recruiting - Canine Retraction Clinical Trials

Poul Gjessing Versus T Loops for Orthodontic Maxillary Canine Retraction

Start date: August 1, 2022
Phase: N/A
Study type: Interventional

Poul Gjessing versus T loops for orthodontic maxillary canine

NCT ID: NCT05643443 Not yet recruiting - Canine Retraction Clinical Trials

Effect of Gradually Increasing Force Magnitude on the Rate of Canine Retraction Randomized Controlled Trial

Start date: December 2022
Phase: N/A
Study type: Interventional

Therefore the aim of the current randomized controlled clinical trial is to investigate the effect of gradually increasing force magnitude versus constant force magnitude on the rate of tooth movement in a canine retraction model, furthermore investigate the effect of the two force systems on the ratio of cytokines and the pain experienced by the patient. Research question: In adult orthodontic patients requiring bilateral maxillary canines retraction, will gradually increasing force magnitudes accelerate the rate of canine retraction in the experimental side when compared to the control side?

NCT ID: NCT04226469 Recruiting - Healthy Clinical Trials

Gingival Crevicular Fluid Characterization During Orthodontic Treatment

Start date: January 1, 2019
Phase:
Study type: Observational

During Orthodontic tooth movement, teeth are moved through alveolar bone under applied forces. The applied mechanical loading force must be transferred to the alveolar bone via periodontal ligament (PDL). This process of mechanotransduction stimulates bone remodeling during which osteoblasts produce bone on the tension side and osteoclasts resorb bone on the compression side of the PDL. Complex interactions between osteoblasts and osteoclasts involve numerous biologic molecules including cytokines and growth factors. During the tooth movement, the expression of cytokines such as interleukin (IL)-1β, IL-6, IL-8, prostaglandin E2, RANKL and MMP1 in PDL will be up-regulated. The sequence of events from the mechanotransduction commanding the tightly controlled accomplishment of osteogenesis attention sides and osteoclastogenesis at compressive sides is not completely understood. The gingival crevicular fluid (GCF) is a transudate of interstitial tissues that is produced by an osmotic gradient and it is released into the crevicular crevices at a flow rate of about 3 ul/h. Orthodontic treatment is triggered by an inflammatory process and it has been hypothesized that the quantification of specific biomarkers within the GCF can be determined using Periotron. However contrasting results have been reported in the literature, which studies showing both increased or unchanged GCF volumes incident to orthodontic treatment. Given that the orthodontic treatment is triggered by a set of inflammatory cytokines that are released into the crevicular fluid during the mechanical loading, and its homeostasis is dependent on mechanical stimulation. An understanding of the biological response of crevicular fluid to mechanical loading could further advance the knowledge of orthodontic treatment. In this study, the investigators will investigate the biological response of gingival crevicular fluid before and after the initial wire placement of orthodontic treatment to determine the differentially expressed genes and proteins related to mechanotransduction.

NCT ID: NCT04020952 Completed - Canine Retraction Clinical Trials

Effect of Archwire Gauge on the Rate of Canine Retraction

Start date: September 10, 2019
Phase: N/A
Study type: Interventional

trial will be done to evaluate the effect of archwire gauge on the rate of canine retraction, canine tip and torque, root resorption and loss of anchorage in maxillary dental protrusion cases requiring first premolars extraction.

NCT ID: NCT03308851 Terminated - Clinical trials for Orthodontic Treatment

Evaluation of the Effects of Osteoperforation and Piezocorticision on Canine Retraction

Start date: January 1, 2018
Phase: N/A
Study type: Interventional

The primary objective of this research is to compare the rate of canine retraction following the osteoperforation and piezocorticision procedures in cases of first premolar extractions. The secondary objectives are to compare the second order movement of the canine (tipping), the amount of root resorption associated with the procedures, the inflammation process by measuring the inflammatory markers in the gingival crevicular fluid, the loss of posterior anchorage by measures on the cone beam computed tomography (CBCT) 3-dimensional radiograph and on the casts and to evaluate the pain level and the impact on quality of life following each procedure using the questionnaire of the visual analogue scale (VAS) of pain.
