Active clinical trials for "Malocclusion, Angle Class II"

The study aimed to estimate clinically an influence of 635nm diode laser on the primary and secondary stability of orthodontic mini-implants placed in a maxilla, to assess mini-implants failure rate (mini-implant loss) and to evaluate a pain level after the treatment. The randomized clinical split-mouth trial included 15 subjects, 30 implants (Dual Top Anchor System, Seoul, Korea) with a diameter 1.4mm and length of 10mm. Mini-implants were placed in the area of the attached gingiva between the second premolar and first molar teeth 2 mm below the mucogingival junction of both sides of the maxilla in 15 patients.

The randomized clinical split-mouth trial included 15 subjects, 30 implants (Dual Top Anchor System, Seoul, Korea) with a diameter 1.4mm and length of 10mm. Mini-implants were placed in the area of the attached gingiva between the second premolar and first molar teeth 2 mm below the mucogingival junction of both sides of the maxilla in 20 patients (13 women and 7 men; age: 32.5 ± 6.1 years).

The study aimed to evaluate the influence of a 635nm diode laser on the stability of orthodontic mini-implants in vitro, as well as mini-implants failure rate (mini-implant loss) and patients pain level after the treatment. A randomized clinical split-mouth trial was concluded with 22 subjects (14 women, 8 men), 44 orthodontic mini-implants with a diameter 1.4mm and length of 10mm. Mini-implants were placed between teeth 3 and 4; and 13 and 14 (Universal Numbering System), in the area of the attached gingiva, 2 mm below mucogingival junction.

The aim of this clinical prospective study will be directed to evaluate two approaches of micro-osteoperforations (MOPs) during orthodontic canine retraction.

A randomised controlled clinical trial to compare the effectiveness of two functional appliances in the correction of a Class II malocclusion. (Class II malocclusions are where upper front teeth bite significantly further forward in relation to lower front teeth). Null hypothesis: There is no significant difference between the Button & bead and Twin-block appliances with regard to time taken to reduce the overjet

To investigate each treatment modality in its "optimal" environment to avoid operator experience bias. Therefore we propose to operate out of three "specialist centres" with specific units providing one modality alone Which of the three orthodontic appliances does achieve best clinical progress, produce least discomfort to the patient, minimize the time taken for completion of treatment and maximize compliance.

The study is to evaluate the effect of 3D printed modified Twin Block Appliance on skeletal Class II profile correction. The null hypothesis of this research is that use of 3D Printed Twin Block is not able to induce skeletal rather than dental effects for correction of the skeletal Class II malocclusion in comparison with untreated growing Class II control subjects.

The aim of this longitudinal randomized investigation is to determine the long-term effects of early headgear treatment on craniofacial structures and dental arches, compared to treatment started later, during the most active growth period in Class II patients. The aim was further to find out the possible benefits and the burden of early treatment to the patients and parents of these common malocclusions, when compared to groups treated later, but with the same methods as much as possible. The hypothesis is that the timing of treatment has significant effects on orthodontic treatment total time, the general outcome of the treatment, and the compliance of the patient.

Acceleration of orthodontic tooth movement persuades tremendous rise in the interest of adolescents and aduts, as it not only shortens the treatment duration but also lessens the incidence of white spot lesions, root resorption, periodontal and other soft tissue problems. Minimal invasive techniques i.e.both piezocision and micro-osteoperforations had promising results in accelerating tooth movement. Therefore current study will provide evidence for better minimal invasive technique in terms of reducing treatment time and patient comfort.
