Technical Field

The invention relates to a false tooth manufacturing tool, in particular to a guide plate for assisting tooth arrangement when a complete false tooth is manufactured.

Background

Currently, the complete denture artificial tooth arrangement work is mainly carried out manually by a dental technician or assisted by a semi-elliptical flat plate. The traditional method has the limitations that the manual operation cannot accurately control the arrangement position and the direction of the artificial teeth in the median occlusion, and the requirement on a technician is high, so that the traditional method depends on the experience of the dental technician to a great extent; meanwhile, the later adjustment occlusion difficulty of the doctor is large, and the operation time is long; the patient can open the mouth for a long time during the treatment, which results in poor treatment experience and poor stability of the false tooth during the use.

The complete denture belongs to one of movable dentures, and is different from a local movable denture in that when the complete denture is arranged, balanced occlusion needs to be achieved, namely when the lower jaw extends forwards and moves laterally, a plurality of artificial teeth are contacted simultaneously, so that the denture is favorable for the stability, and the chewing efficiency is further improved. Therefore, it is more necessary to precisely control the position and direction of the artificial tooth arrangement.

On the base, a bevel is formed, which forms an angle with the base, which angle serves to guide the lateral incisor to form the proper slope of the incisor.

The bottom of the first premolar locating block (10) on the right side is square and 0.5mm high. This distance guides the tip of the first premolar tongue 0.5mm from the occlusal plane. An inclined plane is formed from the middle line of the bottom to the far-middle side surface, and a certain angle is formed between the inclined plane and the bottom, wherein the angle is the inclination of the cusp and is used for determining the rotation angle of the tooth body in the near-far-middle direction.

The second front molar positioning block (11) on the right side is in an inclined plane shape, and the inclined plane and the bottom surface form a certain angle which is the inclination of the cusp.

The first molar positioning block (12) on the right side is square and is divided into four equal parts, the part corresponding to the tongue tip in the middle is hollowed out, and the tongue tip in the middle is guided to be in contact with the occlusion plane; the thickness of the part of the far-middle tongue tip corresponding to the near-middle cheek tip is 0.5mm, and the distance between the near-middle cheek tip and the far-middle tongue tip is guided to be 0.5mm from the occlusion plane; the thickness of the corresponding part of the far and middle buccal cusps is 1.0mm, and the far and middle buccal cusps are guided to be 1.0mm away from the occlusal plane.

The inclination of the cusp mentioned in the above-mentioned positioning block is determined to be 20 ° according to the angle commonly used for each brand of resin teeth.

The tooth arrangement guide plate is used in the step of arranging the complete denture artificial teeth.

When the tooth arrangement guide plate is installed, the lower jaw wax dike is cut off by 1mm, the plane plate (1) is fixed on the lower jaw wax dike, the upper surface of the plane plate is level with the occlusal plane, and the cusp (or the cutting ridge) contacted with the plane plate is positioned on the occlusal plane. The midline of the plane plate corresponds to the midline of the dental arch.

The radian baffle (3) is inserted on the plane plate, the metal sheet (7) is enclosed on the outer side of the wax dike of the upper jaw, the position of the tail end of the metal sheet (7) is determined according to the radian baffle, the tail end of the metal sheet (7) is inserted into the slot (4) in the rear part of the plane plate (1), and the radian formed by the metal sheet (3) can be used for recording the dental arch radian formed by the wax dike. Then, the upper jaw wax dike is cut down to reserve positions for the positioning block (2) and the artificial tooth.

And (3) placing the arch radian recorded by each positioning block (2) with reference to the metal sheet (7) at a corresponding position. The front tooth positioning blocks (8, 9) should ensure that the inclined plane inclines towards the front lower part and the side surface is parallel to the central line of the dental arch, so that the inclination of the incisal tract formed by the inclined plane is correct. When the personalized tooth arrangement is carried out, the positioning blocks (10, 11, 12 and 13) of the back teeth are rotated. The positioning block (2) is adsorbed on the plane plate (1) by magnetic force, and has enough force for positioning.

When the artificial teeth are arranged, the labial surface of the artificial teeth is tightly attached to the metal sheet (7) or keeps a proper distance with the metal sheet (7) according to the requirement of a patient by referring to the arch radian recorded by the metal sheet (7). The artificial teeth have their cutting crests (or cusp tops) abutted against the positioning block (2) or the plane plate (1), and the distance between the cutting crests (or cusps) and the occlusion plane can be determined, i.e., the height position of the artificial teeth arrangement is determined. For the first molar and the second molar, the four cusp vertex positions and the labial surface positions are determined, and the artificial teeth are accurately positioned. For other tooth positions, the axial direction of the tooth body still needs to be determined. For the first premolar and the second premolar, the distal cuspid ridge of the tongue tip is abutted against the inclined plane of the corresponding positioning block, and the position of the labial surface is determined according to the metal sheet, so that the axial direction of the teeth can be determined, and the accurate positioning of the tooth body is realized. For anterior teeth, the cutting ridge of the artificial tooth is abutted against the inclined plane, and the position of the labial surface is determined according to the metal sheet, so that the axial direction of the artificial tooth can be determined, the tooth body can be accurately positioned, and meanwhile, a proper incisal path inclination is formed.

When the second molar is used for forming forward extending balanced occlusion, the far middle cusp of the second molar is tightly abutted against the inclined plane of the corresponding positioning block, and the near middle cusp keeps contact with the plane of the positioning block, so that the tooth body can be positioned.

After the artificial tooth is accurately positioned, the artificial tooth is fixed on the wax dike by wax.
