Fixed asymmetrical occlusal pad combined with cast crown to release interlocking device

Abstract

The invention relates to a fixed asymmetrical occlusal pad combined with a cast crown unlocking occlusal device, which includes an upper jaw part and a lower jaw part; the upper jaw part includes upper left / right first premolars to first molars or second Molar casting metal crowns, Hyrax spiral expanders placed in reverse, left / right anterior and posterior two palatal rods; mandibular part includes mandibular first premolars to mandibular first molars or second molars cast metal joints The cast metal crowns are hollowed out at the corresponding cusps, and the buccal and lingual sides of the cast metal crowns of the mandibular first premolars and mandibular first molars are respectively welded with metal traction hooks. Advantages of the present invention: 1) Smaller volume, less foreign body sensation, and at the same time bonded and fixed, the requirement for patient compliance is reduced, and the orthopedic effect is more stable. 2) Connect multiple posterior teeth of interlocking occlusion into a whole, which can avoid the side effect of vertical elevation of teeth that may be caused by interactive traction. 3) The device can also coordinate the width of the upper and lower dental arches while releasing the locking teeth.

Description

Technical field: [0001] The invention relates to an oral orthodontic appliance, in particular to a fixed asymmetric occlusal pad combined with a cast crown to unlock the occlusal device. Background technique: [0002] According to the buccolingual positional relationship of the upper and lower posterior teeth, incisors can be clinically divided into positive and inverse. Among them, positive lock occlusion is more common clinically, which means that the lingual slope of the tongue tip of the maxillary posterior teeth is located on the buccal side of the buccal slope of the buccal cusp of the mandibular posterior teeth, and the occlusal surface has no occlusal contact. The orthoocclusion of individual teeth can be further divided into orthoclenching of individual teeth; unilateral orthoclenching of the upper and lower second molars, unilateral orthoclenching of most posterior teeth and bilateral orthoclenching of majority of posterior teeth. [0003] The unilateral majority ...

This has a greater adverse effect on the functional movement of the patient's jaw and chewing movement

However, patients with facial asymmetry deformity caused by all ortholocking occlusal teeth on one side can only use the opposite side for occlusal function because all the posterior teeth do not touch, which can easily induce temporomandibular joint diseases, thereby causing mandibular abnormalities. The left and right bones develop asymmetrically, resulting in a deviated face, which will cause a great psychological and mental burden to the patient
