Comparative evaluation of the post Orthodontic occlusion in patients Who have completed finishing and Detailing and those who have not, Using t scan: a follow up study

Abstract

ABSTRACT Introduction: The phases of orthodontic treatment include Initial Leveling and Aligning, Space closure, Finishing Detailing and Settling and Retention. The phase of finishing and detailing in orthodontic treatment has a crucial role in refining the occlusion and ensuring long-term stability (1) Occlusion of the patient affects the orofacial muscles, the health of the Temporomandibular joint, and the ligaments and nerves that surround it. The function of the masticatory system and post-orthodontic stability are all impacted by these elements. (3) The study aims to assess the post-orthodontic occlusal characteristics in patients who have undergone meticulous finishing and detailing according to the given guidelines and those who do not meet the required standards, using T Scan. This study will guide the practitioners in refining their treatment protocol to enhance occlusal stability and long-term retention. Materials and methods: The subjects were distributed into Group A and B after inspection of the casts and radiographs based on the inclusion criteria which is similar to the parameters set by the American Board of Orthodontics. The T Scan was used to record the bite forces of 42 patients who had undergone debonding at three time intervals- T1, T2 and T3. The occlusal parameters that were evaluated are- 1. Occlusion Time 2. Disclusion time vi 3. Total Antagonism (%) 4. % of Force Distribution between Right and Left occlusion 5. The Anterior- Posterior % occlusal force ratio in the anterior and the posterior aspect After Clinical Examination and before recording the T Scan Data, every patients tooth dimensions and details regarding teeth present were entered into the T Scan software. The patient was then trained to bite in Centric occlusion and the sensitivity parameters were adjusted. The patient was asked to bite on the sensor plate and the occlusion was recorded in Maximum Intercuspation (MIP) holding the intercuspation into MIP. The scan was repeated 3 consecutive times and the average value was taken into consideration.
