Conditions

Nuerosensory Disturbance of Inferior Alveolar Nerve after orthosurgery. Injury of trigeminal nerve, unspecified side

Interventions

Intervention 1: Intervention group: Posnik Mandibular Osteotomy Group (Inferior-Internal), In the intervention group, after pre-surgical procedures such as obtaining CBCT and determining the mediolate
surgical procedures will be performed routinely and after the patient was anesthetized and an incision will be made in the retromolar region on both sides and access will be gained using an oscillatin
