Instrument for accurate positioning of occlusion plane

Abstract

An instrument for accurate positioning of occlusion plane comprises a surface plate closely attached to a complete denture plane, an interpupillary line reference plate, a left ala-tragus line reference plate and a right ala-tragus line reference plate, and the latter three are respectively provided with a pupil connecting rod sliding groove, a left ala-tragus connecting rod sliding groove and a right ala-tragus connecting rod sliding groove. A right pupil connecting rod with millimeter scale and a pointer, and a left pupil connecting rod with millimeter scale and a pointer are installed in the pupil connecting rod sliding groove; a left nosewing connecting rod with millimeter scale and a pointer, and a left tragus midpoint connecting rod with millimeter scale and a pointer are installed in the left ala-tragus connecting rod sliding groove; and a right tragus midpoint connecting rod with millimeter scale and a pointer, and a right nosewing connecting rod with millimeter scale and a pointer are installed in the right ala-tragus connecting rod sliding groove. According to the present invention, pointers can be adjusted to objectively and precisely observe whether a front tooth region plane is parallel to a pupillary line, a nosewing root point line and an ala-tragus midpoint line. The connecting rod sliding grooves are used for retaining the pointer scale connecting rods, and can move the pointer connecting rods along the grooves. By moving the connecting rods, the instrument for positioning of occlusion plane can be suitable for patients with different facial sizes.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a precise positioning Plane. Background technique: [0002] When performing a complete denture restoration for a patient, the anterior teeth of the complete denture must be reached The plane is parallel to the line connecting the pupils on both sides, the posterior teeth area The plane is parallel to the alar tragus line, so that the complete denture can best fit the human anatomical structure, and achieve maximum coordination with the masticatory system such as the temporomandibular joint. Therefore, in the process of making complete dentures, it is necessary to use Plane guide to inspect the anterior region of a complete denture Line connecting the plane and bilateral pupils, posterior teeth area Whether the plane is parallel to the alar tragus line. However, the existing methods are all single-handedly The flat guide is placed in the mouth so that The plane pla...

Problems solved by technology

[0003] At present, when making complete dentures for patients with complete tooth loss clinically, there is a lack of accurate Planar positioning instrument or equipment, capable of objective and accurate inspection Whether the plane is parallel to the line between the pupils and the line between the nose and the tragus, if not parallel, it will accurately indicate the difference, which is convenient for the doctor to make objective and precise adjustments
