Background technique

力的能力最强，如果控制得当，患者使用这样的全口义齿不会出现疼痛不适。如果受力不均衡，比如作用力位于偏离中心的某一点或者出现倾斜作用力，那么作用力分布不均衡，义齿会出现翘动，摆动或滑动，作用力会导致支持组织某些位置出现受力过大，过大的受力可能会导致局部疼痛，或者长期作用下会导致牙槽骨吸收。Different from natural teeth, traditional complete dentures are mucosa-supported dentures. The viscoelastic nature of the mucous membrane causes the complete denture to have greater instability in the mouth, similar to a ship floating in shallow water. If a vertical force is applied to the center of the entire supporting tissue of the complete denture, the force will be evenly distributed throughout the support. Tissue, the entire supporting tissue is evenly compressed and sinks, and the supporting tissue tolerates this time

The ability to force is the strongest, and if properly controlled, the patient will not experience pain and discomfort when using such a complete denture. If the force is not balanced, such as the force is located at a point off-center or there is an oblique force, then the force distribution is not balanced, the denture will warp, swing or slide, and the force will cause the support tissue to be stressed in some places Excessive force may cause local pain, or cause alveolar bone resorption under long-term action.

The production of complete dentures is a complex operation that requires many procedures. There are more or less errors in the completed complete dentures. After the upper and lower complete dentures are inserted into the patient's mouth, there may be some local interference points or early contact points. , destabilize the denture. Due to the instability of the base of the complete denture, if a non-central point is subjected to force, the complete denture does not remain stationary, but slides, swings, and tilts. The occlusal contact of the upper and lower jaws occurs in the position. This process is very fast and is generally difficult to detect. Therefore, when examining with occlusal paper, there will be many false occlusal contact points on the surface of the upper and lower complete dentures. It is difficult to distinguish the initial true occlusal contact high point or interference point. After wearing such a complete denture with unbalanced occlusion, the clinical manifestations are local tender ulcers on the upper and lower mucosa.

An embodiment of the present invention provides an occlusal auxiliary inspection adjuster for a complete denture. Please refer to FIG. 1 to FIG. 7 . The complete denture occlusion auxiliary inspection adjuster includes: a positioning plate 10. The positioning plate 10 is used to be arranged on the upper jaw. On the oral denture 1; the fixed bracket 20, the fixed bracket 20 is used to be arranged on the mandibular complete denture 2, and is connected with the center of the relative base lingual side of the mandibular complete denture 2; the adjusting member 30, the adjusting member 30 is arranged on the fixed On the bracket 20, and located at the center of the fixed bracket 20, when the maxillary complete denture 1 and the mandibular complete denture 2 are engaged, the adjustment member 30 is in contact with the positioning plate 10; wherein, at least part of the adjustment member 30 is relative to the fixed bracket 20 is movably arranged in a direction toward or away from the positioning plate 10 .

The occlusal auxiliary inspection adjuster for a complete denture according to an embodiment of the present invention can obtain stable and correct occlusal contact points for the maxillary complete denture 1 and the mandibular complete denture 2 through the positioning plate 10 , the fixing bracket 20 and the adjusting member 30 . In specific use, the positioning plate 10 is set on the maxillary complete denture 1, the fixing bracket 20 with the adjusting member 30 is installed on the mandibular complete denture 2, and the maxillary complete denture 1 and the mandibular complete denture 2 are occluded in the oral cavity , by gradually adjusting the position of the adjusting member 30, the center of force is always maintained at the center of the supporting tissue in the coverage area of the maxillary complete denture 1 and the mandibular complete denture 2, avoiding the need for the maxillary complete denture 1 and the mandibular complete denture 2 Unstable, the occlusal high point or interference point can be gradually and accurately determined to avoid misjudgment caused by the unstable base of maxillary complete denture 1 and mandibular complete denture 2, and finally achieve the stability of maxillary complete denture 1 and mandibular complete denture 2 Correct bite.

It should be noted that, because the fixed bracket 20 is connected with the center of the lingual side of the relative base of the mandibular complete denture 2 (it can be understood that the fixed bracket 20 is connected with the center of the lingual side of the left and right bases of the mandibular complete denture 2, the fixed bracket 20 The two ends are clamped in the middle of the lingual side of the base, as shown in Figure 1), that is, the two connecting ends of the fixed bracket 20 and the mandibular complete denture 2 are clamped in the middle space formed by the mandibular complete denture 2, and the fixed bracket The center of 20 is consistent with the center of the denture, and does not affect the movement of the tongue, so it will not affect the balance of the mandibular complete denture 2. Moreover, since the adjusting member 30 is located at the central position of the fixing bracket 20, when the adjusting member 30 is in contact with the positioning plate 10, the force of the mandibular complete denture 2 is evenly distributed to the supporting tissue by realizing the central occlusal contact, preventing the The complete denture 2 is supported by the mucosa and has a large warping, swinging or sliding. At this time, the occlusal high point or interference point can be accurately confirmed.

It should be noted that the adjusting member 30 is located at the center of the fixing bracket 20 , that is, the distance between the adjusting member 30 and the opposite sides of the mandibular complete denture 2 is the same. For example, if the fixing bracket 20 is a symmetrical structure, the adjusting member 30 The center line of 20 intersects with the symmetry line of the fixing bracket 20 itself. The central position here is an ideal position. If the fixed bracket 20 itself is an irregular structure, its central position can also be understood as the center of the coverage area of the mandibular complete denture 2, including the front and rear and left and right centers. It is to reflect that when the adjusting member 30 is in contact with the positioning plate 10, the front and rear and left and right forces of the mandibular complete denture 2 are balanced, thereby ensuring that the mandibular complete denture 2 will not warp, swing or slide. Of course, in actual use, if the installation deviates in a small range, it will not have a significant impact on the whole.

In one embodiment, the positioning plate 10 is arranged at the center position of the maxillary complete denture 1 , and when the maxillary complete denture 1 is engaged with the mandibular complete denture 2 , the adjusting member 30 is perpendicular to the positioning plate 10 . The positioning plate 10 is arranged on the side of the maxillary complete denture 1 facing the lingual side, and the side of the maxillary complete denture 1 facing the lingual side is an installation surface, so the central position of the installation surface can be determined, that is, the central position, Thus, the positioning plate 10 is installed at the central position of the maxillary complete denture 1. At this time, since the adjusting member 30 is located at the central position of the fixing bracket 20, after the adjusting member 30 contacts with the positioning plate 10, the maxillary complete denture 1 And the mandibular complete denture 2 is in a balanced position.

In one embodiment, the surface of the positioning plate 10 facing the adjusting member 30 is a plane, and the fixing bracket 20 is installed on the mandibular complete denture 2, so when the patient is occluded, the movement state of the fixing bracket 20 is basically consistent with the mandibular closed arc, At this time, the adjusting member 30 is in contact with the plane of the positioning plate 10 to form a fulcrum, which can maintain the stability of the complete denture, and form three fulcrums with the bilateral temporomandibular joints to form a stable structure, which avoids joint instability and complete dentures. Dentures are unstable. The height of the adjusting member 30 can be adjusted by rotating, gradually reducing the height until the artificial teeth of the complete denture are in contact, and gradually adjust the grinding step by step until all the contacts are uniform. Stable, the occlusal contact points that appear gradually in this way are truly abnormal occlusal contact points, which are easy to find and adjust the occlusion, which solves the occlusion problem of the complete denture.

In one embodiment, the positioning plate 10 is a metal plate, and the metal plate is pasted with the maxillary complete denture 1 . The metal plate can ensure the structural stability of the positioning plate 10, not only can prevent deformation and other phenomena, but also has a long service cycle, and no problems will occur during use.

The sleeve 31 is fixedly arranged on the fixed bracket 20 to ensure that the adjusting member 30 is located at the central position of the fixed bracket 20, that is, there will be no positional deviation, and the fastener 32 moves relative to the sleeve 31 to adjust the positioning plate 10 and the positioning plate 10. Fixing the distance between the brackets 20, ie, adjusting the height of the support point, gradually determines and eliminates abnormal occlusal contact points.

In one embodiment, as shown in FIG. 7 , the fastener 32 includes a stud segment 321 and a ball 322 , and the stud segment 321 is threadedly connected with the sleeve 31 , so that when the stud segment 321 is rotated relative to the sleeve 31 , The fastener 32 moves along the axial direction of the sleeve 31 , and the balls 322 are used to contact the positioning plate 10 . The arrangement of the stud segment 321 can control the moving distance of the fastener 32, and the ball 322 acts as a support point in contact with the positioning plate 10. The ball 322 is rotatably arranged on the stud segment 321, and the ball 322 locates the plate 10 in a point-like shape. Contact can guide the joint to automatically move into a stable neutral position during the occlusion process, reducing the error caused by occlusal instability. By gradually reducing the height of the support point, the early contact point or interference point gradually appears, and the grinding is gradually adjusted. Finally, a stable and correct occlusal contact point can be obtained.

In one embodiment, the fastener 32 is a screw, and the pitch of the screw is 1 mm (for every 360-degree rotation, the height changes by 1 mm, and the height is adjusted by turning the screw). The patient loosens the bite, and after stabilization, the screw height is gradually reduced until the maxillary complete denture 1 and the mandibular complete denture 2 are in contact, and then the contact surface with contact is started to be ground, and the central screw is continuously reduced until an acceptable uniform bite is obtained. touch. Since the point of force is always on the central screw, the early contact points and interference points of the complete denture do not affect the stability of the denture.
