View clinical trials related to Orthodontic Tooth Movement.
Filter by:A split-mouth study is conducted in order to evaluate the impact of orthodontic movement on the expression of gingival crevicular fluid miRNAs related to inflammation and osteoclastogenesis during canine distalization following asymmetrical extraction treatment of upper first premolars. Samples of gingival crevicular fluid on the mesial and distal side of the canines to be examined will be performed during the baseline and during various follow-ups.
Aim of the present study is to evaluate the effect of low-level laser therapy on bone quality and quantity with orthodontic tooth movement.
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.
This three-arm cross-over randomized clinical trial (allocation ratio of 1:1:1) will aim to explore whether the application of intermittent vibratory forces modify RANKL and OPG concentrations in patients undergoing orthodontic treatment with clear aligners. The specific objective will be to compare gingival crevicular fluid concentrations of RANKL and OPG among groups according to the application or not of Acceledent® treatment at different time points and frequencies of aligner changes.
This clinical trial evaluated the efficacy of micro osteoperforations in accelerating the retraction of maxillary incisors.
The aims of this study will be to evaluate if a Lower Level Laser Therapy (LLLT): (1) enhances the levels of important pro-inflammatory chemokines involved in the bone remodeling process; (2) increases the rate of orthodontic tooth movement (OTM) on human subjects.
Objectives: The aim of this study is to investigate the effect of photobiomodulation therapies on root resorption compared with the placebo group. Materials and Methods: 30 patients, who were admitted to the …………. University Faculty of Dentistry Orthodontics Department for treatment, with an indication of upper right 1st premolar tooth extraction was included. Before the individuals' orthodontic treatment, 0.022 slot MBT brackets and tubes were placed on the maxillary 1st premolar and molar. A 150g buccal tipping force was applied to the 1st premolar. Individuals were then randomly divided into 3 groups. For the first group; laser application was performed with a 810 nm GaAlAs laser device at 0,3,7,14,21 and 28 days to 8 J/cm2. Second group; an LED application according to the manufacturer's instructions with a 850 nm wavelength and 20 mW/cm2 output power for 10 minutes per day during the experiment. Third group; a placebo therapy was completed whereby a laser device that did not make active pulses was used. At the end of four weeks, the amount of root surface resorption was compared using micro-CT imaging after the extraction of the teeth.
The aim of this randomized split-mouth study was to quantify simultaneously 30 analytes including cytokines, chemokines and growth factors in gingival crevicular fluid (GCF) in response to different magnitudes of forces during maxillary canine distalization. The upper right and left canines were distalized using a continuous force of 75 g or 150 g in 15 individuals who had Class II division I malocclusion requiring bilateral extraction of maxillary first premolars. GCF samples were obtained from the tension and the pressure side of each canine at appliance placement and after force application at 24 hours and 28 days. A multiplexed bead immunoassay was used to quantify 30 analytes simultaneously. The effect of force, side and time on the analyte levels were analyzed with Brunner-Langer method.
This study will compare the techniques of piezocision and alveolar corticotomies in accelerating orthodontic retraction movement of canines. In a second phase, this clinical trial will evaluate the effectiveness of micro-osteoperforations in accelerating the retraction of maxillary incisors.
