Brief Summary:
Long-term studies have shown that various occlusal changes occur after the active phase of orthodontic treatment some of these changes are unwanted changes and are considered as relapse The retention appliances are used to maintain the arch dimensions and alignment of the teeth after completion of the orthodontic treatment One indicator of the functional state and health of the masticatory system is maximum voluntary bite force MVBF Its values vary in accordance to the location of measurement highest at the first molar lower at the incisors People with pronounced horizontal craniofacial growth have somewhat higher values of MVBF and those with vertical growth have lower values than do those with an average growth pattern Clinical case reports and descriptive histologic data exist suggesting that bone and tooth remodeling persist for extended periods after removal of appliance or deactivation A reflection of bone remodelling can be found in the gingival crevicular fluid GCF of moving teeth with decrease or increase in the concentration of biomarker This prompted us to evaluate the expression of variation in bone turnover marker levels CTX-Bone resorption marker and BALP -Bone formation marker during the retention period The International Osteoporosis Foundation IOF and International Federation of Clinical Chemistry IFCC have recommended C-terminal telopeptide of type I collagen CTX as one of the reference for BTMs Hence The present trial will be undertaken to assess the changes and compare if there is any difference in bite force and change in level of bone biomarker biomarker CTX type 1 collagenC-terminal telopeptide of type I collagen and bone specific alkaline phosphataseBALP in post orthodontic treatment hypodivergent and hyperdivergent cases using beggs retainer over 12 months of period of retention
Detailed Description:
The proposed study will be a non-pharmacological two arm parallel Prospective single blind clinical trial to evaluate if there is a difference in retentive characteristics of dentition in two group of post orthodontic treatment patients with vertical growth pattern patients in one group and horizontal growth pattern patients in other group of patients The present study will be conducted in the Department of Orthodontic and Dentofacial Orthopedics PGIDS Pt BD Sharma University of health sciences Rohtak The study will be carried out after the institutional approval obtained from ethical committee
Patient will be allocated to two different study group by the investigator the data analyst will be blinded regarding the intervention group The sample size for the proposed study was calculated by using the formula Total sample size N 2σ 2 Zβ Zα2 2 difference of mean 2 sample size of 20 patients was calculated by using the above formula at confidence interval 95 with power 99
GROUP 1 patient with vertical growth pattern have who had undergone fixed orthodontic cases having FMA of 26 0 or more for hyperdivergent cases
GROUP 2 patient with horizontal growth pattern who had undergone Fixed orthodontic cases having FMA of 24 o or less for hypodivergent cases
Changes in levels of bone turnover markers CTX-bone resorption and BALP-bone formation using ELISA These parameters will be charted at T0 T1 T2 T3T4 for each patient
T0 - Records will be obtained at the time of retainer delivery T1 - Records will be obtained after 1month of retainer delivery T2 - Records will be obtained after 3 month of retainer delivery T3- Records will be obtained after 6 months of retainer delivery T4- Records will be obtained after 12 months of retainer delivery
Assessment of bite force will be done using bite force measuring device at T0 - Records will be obtained at the time of retainer delivery T1 - Records will be obtained after 1month of retainer delivery T2 - Records will be obtained after3month of retainer delivery T3- Records will be obtained after 6 months of retainer delivery T4- Records will be obtained after 12 months of retainer delivery
