Pharyngeal Airway Dimensions With Twinblock Versus Myobrace Appliances in Developing Skeletal Class II Patients
Cephalometric Changes in Pharyngeal Airway Dimensions After Functional Treatment With Twinblock Versus Myobrace Appliances in Developing Skeletal Class II Patients: A Randomized Clinical Trial
The goal of this clinical trial is to compare the pharyngeal airway changes after treatment with Myobrace and after treatment with Twinblock in developing skeletal Class II patients.
The main question it aims to answer is: Is the efficacy of the twin-block Vs Myobrace appliances in the improvement of pharyngeal airway dimensions in adolescents having skeletal Class II malocclusion with retrognathic mandible utilizing sagittal pharyngeal airway area measurements.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
SNA
Time Frame: Six months
|
Angle formed between points Sella, Nasion and A point and describes anteroposterior position of the maxilla relative to the anterior cranial base.
|
Six months
|
SNB
Time Frame: Six months
|
Angle formed between points Sella, Nasion and B point and describes anteroposterior position of the mandible relative to the anterior cranial base.
|
Six months
|
ANB
Time Frame: Six months
|
Angle formed between points A, Nasion and B point indicating the skeletal relationship between the maxilla and the mandible.
|
Six months
|
Witts appraisal
Time Frame: Six months
|
The linear distance between the perpendicular projections of points A and B over the functional occlusal plane.
|
Six months
|
FMA
Time Frame: Six months
|
Angle formed between mandibular plane and Frankfort horizontal plane.
|
Six months
|
Pharyngeal air way area measurement
Time Frame: Six months
|
The upper border of Naso Pharyngeal air way area will be delineated by a line extending from the harmonium (H) to the posterior nasal spine.
The lower extent of the NPAA will be traced by marking a line at the tip of the soft palate parallel to the Frankfort horizontal (FH) plane extending to the posterior wall of the pharynx.
The OPAA and LPAA are differentiated by a line drawn at the level of the tip of epiglottis parallel to the FH plane to the posterior wall of the pharynx.
The lower border of the LPAA is defined as a line drawn parallel to FH plane and passing through the anteroinferior most point (C5AI) of the fifth cervical vertebra.
Area will be measured.
