Active clinical trials for "Malocclusion"

This experimental study aims to evaluate the efficiency of the orthodontic removable traction appliance in the treatment of skeletal class III malocclusion. The study sample will consist of 44 patients with skeletal class III malocclusion. The sample will be allocated randomly into two groups: experimental group and control group. The dentoskeletal changes will be assessed by using lateral cephalometric radiographs before treatment and after obtaining 3mm positive overjet.

The objective of this 2-arm parallel double blinded randomized controlled trial is was to evaluate and compare the treatment effects of PowerScope and Forsus in the treatment of Class II division 1 malocclusion. Patient comfort and operator convenience was also assessed and compared .

The main objective of this prospective, controlled clinical study is: To compare the treatment effects of PowerScope2 and Forsus Fatigue Resistant Device in patients with Class II divison1 malocclusion. To compare the treatment effects of PowerScope2 and Forsus Fatigue Resistant Device with the control group. The null hypothesis for this study is that Forsus and PowerScope2 are equally effective in the treatment of ClassII div1 malocclusion.

This experimental study aims to evaluate the efficiency of the Modified Fixed Mandibular Retractor Appliance in the treatment of skeletal class III malocclusion. The study sample will consist of 44 patients with skeletal class III malocclusion. The sample will be allocated randomly into two groups: experimental group and untreated control group. The soft and hard tissue changes will be assessed using lateral cephalometric radiographs before the treatment and after obtaining 3mm positive overjet.

Advances in orthodontics have improved the quality of appliances and treatment protocols, raising the standard of patient care. However, enamel demineralization is still a problem associated with orthodontic treatment, leading to the formation of white spot lesions; this is a grave concern to orthodontists and patients. The overall prevalence of white spot lesions among orthodontic patients has been reported to be between 4.9% and 84%.1 When basic oral hygiene is poor, orthodontic appliances create areas of plaque stagnation, especially around brackets, bands, wires, and other attachments. Levels of acidogenic bacteria, present in the plaque, notably Streptococcus mutans (S mutans), are higher in orthodontic patients than in non-orthodontic patients. This causes demineralization around the brackets and leads to white spot lesions. They are most prevalent around the cervical region of bands in the posterior region, whereas in the anterior region, the lateral incisors in both arches, followed by the canines, are most commonly affected.

Posterior crossbite is a common clinical condition often associated with transverse maxillary deficiency and functional mandibular shift. This frequent malocclusion is not self-correcting and can lead to the development of craniofacial asymmetries and mandibular dysfunction. The aim of the current study was to evaluate maxillary and mandibular arch widths' response to RME when it is anchored to the upper second deciduous molars or to the upper first permanent molars and to create a decision-making protocol for RME therapy in mixed-dentition patients.

This experimental study will evaluate the effect of combined treatment with low-level laser and functional appliances (twin-block) on the correction of Class II malocclusion, compared with the control group treated with functional appliances (twin-block) only. The study sample will consist of 40 patients with Class II malocclusion. The sample will be allocated randomly into two groups: a control group and an experimental group. Functional appliance (twin-block) will be applied for all patients. Low-level laser will be applied for the experimental group only. The skeleto-dental changes occurring after functional treatment will be assessed using cephalometric radiographs; pre- and post- treatment changes for each group will be evaluated individually.

It is a prospective descriptive study to evaluate TMJ disc-condyle-fossa relationship using MRI scan following functional appliance therapy in skeletal Class II Division 2 malocclusion in adolescent females. All records, including MRI scans will be collected at three stages and will be traced for various angular and linear measurements to document the alterations within the condyle glenoid fossa complex Stage- I (pre-treatment), Stage- II (after pre-functional therapy) Stage-III (After 6-8 months of functional appliance therapy that is after correction to Class I molar relation

This open label study is designed to evaluate the ability of OrthoPulse™ to safely and effectively increase the rate of orthodontic tooth movement with fixed appliances.

Orthodontic therapy allows for the treatment of dental malpositions in order to produce an adequate relationship between teeth during occlusion. Conventional orthodontic therapy applies slight forces and moves teeth slowly. It is generally performed during a 2 year minimum of time. Recent studies seem to suggest that orthodontic therapy time can be shortened by surgical assistance (corticotomy). This investigation is aimed to determine the velocity of tooth movement and changes in periodontal clinical parameters between corticotomy-assisted orthodontic therapy and conventional orthodontic therapy.
