Active clinical trials for "Overbite"

this is a controlled clinical trial with 2 groups of patients of class II skeletal discrepancy due to mandibular retrusion one group is treated with twin block functional appliance and the other with twin block combined with low level laser therapy ,the study aims to detect the effect of low level laser on the skeletal outcomes , dentoalveolar outcomes, rate of correction and pain during treatment

Patients with skeletal class II malocclusion who have a retracted lower jaw will be treated in this study. The efficacy of clear Plates in the treatment of Skeletal Class II Malocclusion will be assessed. The skeletal, dental and soft tissues changes resulted by this intervention will be studied and compared with the results of Traditional treatment with fixed appliances.

The purpose of this study is to determine if the Herbst appliance with indirect skeletal anchorage in mini-implants is capable of preventing excessive inclination of the lower incisors at the end of the treatment when compared to the Herbst appliance with dental anchorage and Twin-Block appliances in patients with Class II malocclusion and overjet ≥ 6 mm.

In this study the investigators are going to compare the predictability of the backward movement of upper first molars in patients with the upper dentition more advanced than the lower dentition. The investigators are going to study if the movements that they predict are achieved and in which proportion and compare it between four different aligner systems. The investigators hypothesis is that there are no differences in the predictability of this movement between the four aligner systems.

The aim of this study is to compare the treatment results when treating Class II division 1 malocclusion using the Van Beek-Headgear Activator combination (vBHGA) appliance versus using the Andresen activator.

This clinical study will be directed to compare the effect of presence or absence of third molar on distalization of the upper posterior segment by using carriere motion appliance

Carriere Motion appliance (CMA) was designed to correct a Class II molar relationship into a Class I relationship by distalizing the whole posterior maxillary segment by means of class II elastics and mandibular anchorage. To revoke the adverse effects of CMA with class II elastics, we can use the CMA to distalize the maxillary posterior segment with TADs anchorage using miniscrews. The aim of this study is to evaluate TADs anchored CMA vs. conventionally anchored CMA for distalization of the maxillary buccal segment.

This project examines sleep quality (e.g. prevalence of obstructive sleep apnea(OSA)), dimension of upper airway, jaw function, well-being and quality of life in children with large overjet compared to a control group. In addition, the effect of treatment with a mandibular advancement device (MAD) on sleep quality, upper airway and jaw function are examined, and how these factors affect the children's well-being and quality of life.

There is currently no information on how mandibular advancement therapy could influence three-dimensionally the condylar and mandibular morphology in growing patients affected by Juvenile Idiopathic Arthritis (JIA). Therefore, the aim is to assess the three-dimensional morphological mandibular changes produced by the Invisalign® Mandibular Advancement (MA) (Align Technology, San José, CA, USA) in growing subjects affected by juvenile idiopathic arthritis with unilateral and bilateral JIA and to compare them with not-JIA control subjects

A deep bite is a bite where the upper front teeth cover almost all, if not all the lower front teeth. Currently there is no clarity which of the available treatment approaches is better when these patients still have some baby (deciduous) teeth in their mouths. This study will compare the results of four ways to manage this problem: Delay treatment until all permanent teeth are erupted, Temporary glue some brackets to the upper front teeth and correct the problem with orthodontic wires, Temporary glue some dental material in the back of the front teeth to allow the back teeth to erupt. The amount of improvement (increased exposure of lower front teeth when biting) will be compared between the four treatment options. The reason there is a no treatment group is because a slight improvement of the deep bite happens naturally in some cases. In this case delay of treatment is not a major concern as this bite type can be managed later during permanent dentition.
