View clinical trials related to Class II Malocclusion.
Filter by:This study will collect data to try to assess which one of the two management options works better. The first option involves the use of the bite corrector first and then braces, while the second option involves the temporary addition of small support bone screws with the bite corrector later and then braces. Currently, it is not clearly known if there are important differences between the proposed management options. Such approaches are conventionally used in orthodontic practices. The information collected in this study will be used to compare the differences in the nature of the facial, teeth, and bone changes after the treatment. Questions about the experience while using the devices will be asked.
There is a scarcity in the current literature regarding such appliance and its effect on distalizing the first maxillary molar in absence of the second molar. Therefore, this study was made to evaluate the effect of bilateral distalization of upper first molars in a group of patients after extraction of maxillary second Molars using infra zygomatic mini implants.
Fixed Functional Appliances comparisons in treatment of orthodontic class II malocclusion cases
This study will be directed to evaluate The effect of two different types of fixed functional appliances on the temporomandibular joint. Study design: Prospective randomized clinical study. Study setting and population: This study will be conducted on twenty orthodontic patients. The number of patients was dependent on a power study. Sample size calculation was based on the observed average effect size derived from previous article addressing "the effect of skeletally anchored Forsus FRD using miniplates for the treatment of Class II malocclusion
the objective of the current study is to compare the dentofacial effects of the mini-plate anchored Herbst appliance Versus the dentally anchored Twin force bite corrector Appliance in Young Adult Class II Orthodontic Patients with retruded mandible.
This experimental study will evaluate the effect of an esthetic Twin-block appliance on the correction of class II malocclusion compared with the traditional Twin-block appliance. The study sample will consist of 50 patients with class II malocclusion. The sample will be allocated randomly into two groups: the control group and the experimental group. The traditional Twin-block appliance will be applied for the control group patients, while the esthetic Twin-block appliance will be applied for the experimental group patients. The dentoskeletal, soft tissue changes and esthetic and functional efficacy occurring after functional treatment will be assessed using cephalometric radiographs and profile photographs, pre and post-treatment, and a questionnaire. Changes for each group will be evaluated individually, and the two groups will be compared.
Thirty-eight patients requiring extraction of maxillary first premolars and maximum anchorage to retract the upper anterior teeth will participate in the study. They will be divided randomly into two groups: electrical group and control group. In each group, en-masse retraction will be initiated after completion of the leveling and alignment phase via closed nickel-titanium coil springs applying 250 g of force per side, Mini-implants will be used as an anchor unit. The dental changes will be detected using dental casts and to evaluate the rate of teeth retraction.
Thirty two patients requiring extraction of maxillary first premolars and en-masse retraction of upper anterior teeth will participate in the study. They will be divided randomly into two groups: electrical group and control group. In each group, en-masse retraction will be initiated after completion of the leveling and alignment phase via closed nickel-titanium coil springs applying 250 g of force per side, Mini-implants will be used as an anchor unit. The overall retraction duration will be calculated. The skeletal, dental and soft tissue changes will be detected using panoramic and lateral cephalometric radiographs which will be obtained pretreatment, pre and post en-masse retraction of the anterior teeth.
54 patients who need extraction-based treatment of the maxillary first premolars with subsequent retraction of the maxillary canines will be divided randomly into three groups in this trial. The prolonged duration of the treatment period can cause many side effects such as white spots, caries, periodontal diseases, and pain and discomfort. So many efforts have been made to reduce the treatment time. Many procedures have been introduced to accelerate orthodontic tooth movement, which can category as surgical or non-surgical. Piezocision is a minimally invasive surgical method for accelerating orthodontic tooth movement and shortening treatment time. Low-level laser therapy (LLLT) is one of the physical acceleration methods that have contributed to decreasing treatment time. There are three groups: The first group (control group): the canine retraction in this group will be performed in conventional method. The second group (Experimental group): the canine retraction in this group will be performed in association with piezocision. The third group (Experimental group): the canine retraction in this group will be performed in association with low-level laser therapy.
Sixty patients need extraction-based treatment of the maxillary first premolars with subsequent retraction of the maxillary canines will be divided randomly into three groups: piezocision group, low-level laser therapy group, and control group. In each group, the canine retraction will be started after completion of the leveling and alignment phase via closed nickel-titanium coil springs applying 150 g of force per side. For anchorage, a soldered trans-palatal arch will be used. Pre- and post distalization dental casts will be assessed to study the rate of canine retraction, as well as, canine rotation and anchorage loss over a follow-up period until a class I canine relationship is achieved.
