Correlation of Mandibular Angle and Malocclusion with Hand Grip Strength in Vertical, Horizontal and Average Grower

Background: An orthodontic treatment focuses on improving an individual's facial esthetics and functional occlusion via improved chewing patterns, muscular power, increased force, and occlusal contact area through a more efficient masticatory function. Every decision made during orthodontics treatment will be influenced by the patient’s growth pattern and /or muscle strength.

Objectives: To evaluate the gonial Angle in vertical, horizontal and average grower, to evaluate the hand grip strength in vertical, horizontal and average grower and to correlate between gonial angle with hand grip strength in vertical, horizontal and average growth pattern.

Methodology: We will study a patient group undergoing orthodontics treatment with vertical, horizontal, and average growth patterns in the Orthodontics Department at Sharad Pawar Dental College and Hospital in Sawangi (Meghe), Wardha District. The calculated sample size of the study will be 196, under criteria 49 for vertical, 49 for horizontal, and 98 for the average growth pattern. Both male and female norms for the value are to be evaluated based on the value.

Expected Results: Hand grip strength is to be compared between average, horizontal and vertical growers. Hand grip strength would be inferior in the large gonial angle group compared to the small gonial angle group. Gonial angle is the most conspicuous determining factor of Hand grip strength. Assessment of growth pattern has a vital role in diagnosis and treatment planning.

Conclusion: In the present study it will be an attempt to analyze effectiveness of gonial angle in vertical, horizontal and average growth pattern patients compared with hand grip strength. Subject with large and small gonial angle groups using cephalometric radiograph shall be assessed with hand grip strength. A major finding of this study is that gonial angle is one of the key factors for the strength of Hand grips.
