Masticatory orthodontic appliance and its manufacturing method

摘要

A method of making a dental appliance for repositioning a patient's teeth includes: providing a target dental model of the patient's dental arch in a target tooth arrangement, and providing a combined dental model derived from the target dental model and an initial dental model of the patient's dental arch in an initial tooth arrangement; forming a block-out layer to cover at least one first tooth of the combined dental model; forming a first material layer over the block-out layer and the combined dental model to form a rigid shell; forming a second material layer over at least one first tooth of the target dental model corresponding to the at least one first tooth of the combined dental model; placing the rigid shell against the second material layer and the target dental model to form at least one resilient member in the rigid shell.
