NCT ID: NCT05853211 Not yet recruiting - Clinical trials for Malocclusion, Angle Class II

Therapeutic Effects of Class II Elastics on Aligners in Different Vertical Skelettal Patterns

Start date: May 30, 2024
Phase:
Study type: Observational

The objective is to compare the dento-alveolar therapeutic effects of wearing class II inter-arch traction elastics on aligners versus multi-brackets in an adult population. The principal hypothesis is no significant difference in therapeutic effects of using inter-arch elastics on aligners versus multi-brackets.

NCT ID: NCT05467579 Not yet recruiting - Clinical trials for Juvenile Idiopathic Arthritis

Mandibular Advancement Clear Aligner Treatment in Juvenile Idiopathic Arthritis Subjects

Start date: October 1, 2022
Phase: N/A
Study type: Interventional

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

NCT ID: NCT04028661 Not yet recruiting - Clinical trials for Class II Malocclusion, Division 1

Evaluation of 3D Printed Modified Twin Block for Correction of Skeletal Class II Malocclusion in Growing Females

Start date: August 1, 2019
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03863275 Not yet recruiting - Clinical trials for Class II Malocclusion

Analysis of Muscle Activity With Myofunctional Devices, Using Surface Electromyography

Start date: February 26, 2019
Phase: N/A
Study type: Interventional

Importance and justification The importance of carrying out this study is to verify the electrical activity generated by the masticatory muscles to be able to have clarity of their performance in the development of orthopedic treatment, thus complementing the diagnosis to achieve a more successful treatment with myofunctional device SN1 in Class II malocclusions. In addition, with the results of this study, treatment prediction criteria are provided to the clinician, depending on the thickness of the muscle, more specific equipment will be chosen to solve the malocclusion and prognosis when using the SN1 myofunctional device in class II malocclusions. Additionally, it has academic utility, since there is little scientific evidence about myofunctional SN1 device and its impact on masticatory muscles, thus opening the door to a line of research where this study can be used as a basis for future orthopedic clinical research. in UNICIEO. Added to this and according to the results, the knowledge about the SN1 will be updated, thus providing evidence for the teaching of orthopedics for the students; and also a measurement protocol with electromyography for children will be provided Overall objective To evaluate the electrical activity of the masseter and temporal muscles in patients from 7 to 12 years of age, with skeletal class II who are under treatment with myofunctional apparatus (Sn1), in the UNICIEO orthopedics clinic by means of kinesiological electromyography compare with a control group without use of the device Specific objectives - Determine the activity of the masseter and temporal muscles of patients at rest (without functional orthopedic apparatus) in the two study groups. - To determine the activity of the masseter and temporal muscles of the patients after the use of functional orthopedic equipment (Sn1), after six months of treatment and in the control group without treatment.

NCT ID: NCT03764189 Not yet recruiting - Clinical trials for Class II Division 1 Malocclusion

Evaluation of Micro-osteoperforation on Rate of Maxillary En-masse Retraction

Start date: January 2019
Phase: N/A
Study type: Interventional

accelerated anterior teeth retraction with the help of microosteoperforation procedure and miniscrews.

NCT ID: NCT03635463 Not yet recruiting - Clinical trials for Class II Division 1 Malocclusion

Effect of Modified Twin Block in Skeletal Class II Growing Females With Mandibular Deficiency

Start date: December 2018
Phase: N/A
Study type: Interventional

The aim of this study is to evaluate the treatment effects of conventional twin block appliance versus modified twin block appliance in the treatment of patients in growing stage having skeletal class II division 1 with mandibular deficiency.

NCT ID: NCT03450551 Not yet recruiting - Clinical trials for Malocclusion, Angle Class II

Comparison of Efficacy of Three Orthodontic Appliances

Start date: April 1, 2018
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03085082 Not yet recruiting - Clinical trials for Class II Malocclusion

Study of the Relationship Between Blood Groups,RH and Skeletal Malocclusion : a Cross Sectional Study

Start date: April 1, 2017
Phase: N/A
Study type: Observational

the study is searching if there is a relationship between the blood groups and RH and the skeletal malocclusion using the skeletal class I as a control group
