Embodiment 1

[0047] The manufacturing method of the repositioning occlusal splint for treating the repositionable anterior displacement of the temporomandibular joint disc of the present invention comprises the following steps:

[0048] (1) The patient opens the mouth normally, let the patient protrude the mandible and close the mouth, find the position of the mandibular condyle when the mandible is protruding and in contact with the teeth, record and fix the position;

[0049] Among them, the determination of the position of the mandibular condyle is that when the patient opens his mouth, after the bilateral or unilateral mandibular joints pop and the mouth reaches the maximum, the mandible protrudes forward and closes the mouth to the position where the upper and lower incisal edges or cusps touch in a point-like manner. Open the mouth and close the mouth again and reciprocate the mandibular protruding position. After the bilateral or unilateral mandibular joints do not appear popping sou...

Embodiment 2

[0061] The manufacturing method of the occlusal splint for treating temporomandibular joint disc displacement of the present invention comprises the following steps:

[0062] (1) The patient opens the mouth normally, let the patient protrude the mandible and close the mouth, find the position of the mandibular condyle when the mandible is protruding and in contact with the teeth, record and fix the position;

[0063] Among them, the position of the mandibular condyle is determined when the patient’s mandible is protruded, and after bilateral or unilateral mandibular joints have popping sounds and reach the maximum, the mandible is protruded and closed to the position where the incisal edges of the upper and lower anterior teeth are opposite, and the mouth is opened and closed again. Reciprocate the mandibular protruding position. After the bilateral or unilateral mandibular joints do not appear popping sound, if it still occurs, continue to protrude and adjust the mandibular po...

Embodiment 3

[0076] The accompanying drawing is only a structural diagram, and those skilled in the art can obtain a structural diagram that meets clinical needs by combining the accompanying drawings and clinical practice.

[0077] As shown in the figure, the repositioning occlusal splint for the treatment of the repositionable anterior displacement of the temporomandibular joint disc of the present invention includes 2 pairs of continuous symmetrical molar occlusal sleeves 1 that coincide with the upper dentition, and dental occlusal sleeves 1 on both sides. Connected by the connecting plate, tooth placement holes 4 are correspondingly set in the occlusal sleeve, the connecting plate is arranged on the inner and outer sides, and the shape of the inner connecting plate and the outer connecting plate is consistent with the inner and outer sides of the upper jaw or the top of the upper dentition. The shape of the inner bottom surface of 1 is consistent with the bottom surface of the teeth of...

Abstract

The invention discloses a manufacturing method of a biteplate for treating temporal-mandibular joint disc displacement by 3D printing. The manufacturing method comprises the following steps: (1) mandible condyle process positions of patients are recorded and fixed; (2) craniomaxillofacial surfaces of the patients are shot to obtain conical beam CT data of the patients; (3) upper and lower jawboneparts of the patients are rebuilt; and the head positions of the patients are adjusted according to frankfort planes of the patients; (4) bone tissue CT values, teeth and occlusalf surface areas are selected from three-dimensional drawing software for three-dimensional rebuilding of occulsalf surface data of the patients; (5) occulsalf surface three-dimensional models of the patients are rebuilt in the three-dimensional drawing software; (6) interference parts of the occulsalf surface three-dimensional models are removed; (7) the occulsalf surface three-dimensional models are guided into 3D printer mated software; (8) upper jaw parts and lower jaw parts of occlusal pads are designed; and (9) a 3D printer is used for printing to finish manufacturing of the occlusal pads. Through projectionsformed on the inner side of the biteplate, lower teeth cannot retreat due to stop by lower jaw projections of the biteplate, so that the lower jaws of the patients are maintained in a protraction state to treat the temporal-mandibular joint disc recoverable forward displacement.

Description

technical field [0001] The invention belongs to the technical field of oral medical devices, and in particular relates to a manufacturing method of a repositioning occlusal plate and a repositioning occlusal plate for treating the repositionable anterior displacement of the temporomandibular joint disc. Background technique [0002] Temporomandibular joint disc displacement (anterior disc displacement, ADD) is a common clinical disease in stomatology, which refers to the forward displacement of the articular disc beyond its normal position when the cusps are interlaced above or slightly behind crest). According to whether the disc-condyle relationship can return to normal when the mouth is opened, ADD is divided into reversible and irreversible anterior displacement, that is, during the opening process, the articular disc can bounce back to restore the normal disc-condyle position relationship. It is reversible anterior disc displacement; after the condyle slides forward an...
