Analysis of Occlusal Force Distribution in Digital and Conventional Occlusal Splint

Each eligible patient will be randomly into one of two groups: Group A: The digital splint group, digital splint will be constructed to each patient. Group B: The conventional splint group, conventional splint will be constructed to each patient. * For both groups, thorough clinical examination, scaling and root-planning will be done. Patient will receive a motivational oral hygiene program with detailed explanation regarding the study process and outcome expectations. * A precise history and clinical examination will be done by (F.M) under supervision of Dr S.G. The digital splint construction method: * First, complete arch intraoral digital scans of the maxillary and mandibular arches will be performed using the intra oral scanner following the scanning protocol recommended by the manufacturer. * For inter maxillary relation recording using optical jaw tracking device, step-by-step procedure for tracking and recording the maxillomandibular relationship and mandibular motion by using an optical jaw tracking system will be illustrated to the patient. * The occlusal device will be designed using a CAD software program. * The occlusal device will be printed using a 3D printer * The occlusal device will be finished and polished manually. The conventional splint construction method: * The first step is making an impression using a quick-setting addition polyvinyl siloxane impression material. A stone model will be obtained after pouring the impression using extra-hard dental stone. * In the second visit a face bow transfer and a centric relation record will be utilized to mount the casts on a semi adjustable articulator. * For centric relation recording, a jig will be made with an incisal plateau from modeling plastic impression compound and the jig will be inserted between the central incisors. To measure centric relation as precisely as possible (by avoiding translational movement in the temporomandibular joint), * The jig will be adjusted with a scalpel to cre
