Filter by: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
Various malocclusions require the extraction of the first premolars and retraction of the canines with the need for maximum anchorage. If the canines are pulled into the extraction space using the molar teeth for support, unwanted tooth movement occurs. This study aims to evaluate the effect of temporary anchorage devices and power arms, which are auxiliary orthodontic appliances in reducing undesirable tooth movements.
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.
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
The present day social setup considers facial charisma as an important physical characteristic. The facial characteristics of an individual are measured through anthropometry, photogrammetry, computer imaging and cephalometric radiographs. Cephalometric radiographs offer significant diagnostic information regarding the association between the dental and skeletal structures. By means of photogrammetric measurements, a fresh diagnostic resource is accessible to the orthodontist which permits an intangible, radiation free attainment of measure points of soft tissue with no instrumental expense and radiation to the patient. Orthodontic patients range from adolescents to senior citizens and originate from an assortment of populations, thus an extensive series of representative norms will be ideal. Knowledge of the normal dentofacial outline of every group will make certain better success of treatment to set up the best possible facial agreement. Hence, it is extremely important to assess the soft tissue profile of a patient as it is one of the most vital components of orthodontic diagnosis and treatment planning. The purpose of the present study is to evaluate the photographic characteristics of soft tissue facial profile of patients with class II malocclusion as ethnic differences have been found to be reported in the literature. It is hypothesized that soft tissue facial characteristics on lateral profile photographs and lateral cephalometric radiographs in a sample of local population with class II malocclusion are closely related.
