Class II Malocclusion Clinical Trial
— STFPOfficial title:
Photographic Analysis Of Soft Tissue Facial Profile In Patients With Class II Malocclusion
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.

---|---|---|---|---|
Primary | Mean values of facial profile angles and linear measurements | Mean values of soft tissue angles and linear measurements will be determined both on cephalographs and photographs separately. | Within one week after cephalographs and photographs have been taken. | No |
Secondary | Comparative angular and linear parameters | Mean values of soft tissue angles on cephalographs and photographs will be compared. Similarly comparison of linear measurements on cephalographs and photographs will be performed. | Within two weeks after cephalographs and photographs have been taken. | No |
