Problems solved by technology

[0008] For functional adsorption dentures (BPS), when the initial occlusal relationship is prepared with the centric occlusal tray, due to the soft texture of the silicone rubber, the patient cannot control the force, which may eventually result in a lower initial vertical distance
In addition, the central occlusal tray with silicone rubber is large in size, and it is difficult for the patient to move the mandible according to the doctor's instructions when it is placed in the mouth.

Embodiment 1

[0034] Such as figure 1 with figure 2 As shown, this embodiment provides an improved complete denture maxillary initial mold tray, including a tray body composed of a tray base 1 in the middle and occlusal dykes 2 on both sides. The positions of the two occlusal dykes 2 Corresponding to the alveolar ridges between the first premolar and the second premolar on both sides of the human teeth; one end of the tray body is provided with a tray handle 3 connected to the tray base 1; A plurality of overflow holes 4 are evenly arranged; the width of the occlusal embankment 2 gradually increases from one end close to the tray handle 3 to the other end, and three fixing grooves 5 are arranged at intervals on the occlusal embankment. It should be noted that the maxillary blank tray of the present invention is made of silicone rubber; the angle a between the end surface of the tray handle 3 away from the tray base 1 and the vertical surface is equal to 15°.

[0035] The preliminary occl...

Embodiment 2

[0037]This embodiment is a further improvement made on the basis of Embodiment 1. The specific differences between this embodiment and Embodiment 1 are:

[0038] What needs to be further explained in this embodiment is that the width of the occlusal embankment 2 is 6-8 mm. It should be further explained that the height of the occlusal embankment 2 is 10mm. Specifically, the width of the occlusal embankment 2 can be 6mm, 7mm or 8mm, etc., as long as it is within this range, there is no specific limitation. Since the average width of the maxillary wax occlusal embankment is 6-8mm, the occlusal embankment The width of 2 is between 6-8mm, which is the most appropriate range. At the same time, since the average height of the maxillary wax occlusal embankment is 12mm, after taking an impression as a tray, the impression material may raise the occlusal height by 1-2mm, so It is most appropriate to set the height of the occlusal embankment at 10mm, and the width and height of the occ...

Embodiment 3

[0040] This embodiment is a further improvement made on the basis of Embodiment 1 or Embodiment 2. The specific differences between this embodiment and Embodiment 1 or Embodiment 2 are:

[0041] What needs to be further explained in this embodiment is that the fixing groove 5 is a trapezoidal groove structure with a bottom width and a top narrowness. That is, the inner bottom surface of the fixing groove 5 is equivalent to the lower bottom surface with a larger area in the trapezoidal structure, and the opening at the upper end of the fixing groove 5 is equivalent to the upper bottom surface with a smaller area in the trapezoidal structure, and this trapezoidal groove structure After the material is hardened, Because the opening is smaller than the bottom, the material is not easy to separate from the occlusal embankment, and the material can be firmly stuck on the occlusal embankment.

Abstract

The invention belongs to the technical field of dental molding apparatuses, and discloses an improved complete denture maxillary blank mold tray. The blank mold tray comprises a tray base located in the middle and a tray body composed of occlusion banks on the two sides. The positions of the occlusion banks correspond to alveolar ridge crests between the first premolar tooth and the second premolar tooth on the two sides of human teeth respectively. A tray handle connected with the tray base is arranged at one end of the tray body. A plurality of overflow discharge holes are evenly formed in the tray base. The width of the occlusion banks is gradually increased from one end close to the tray handle to the other end. Three fixing grooves are formed in the occlusion banks at intervals. Whenan impression is prepared from the maxillary blank mold tray, the primary occlusion position relation can be prepared; the length and the position of the tray handle cannot interfere with the motionsof an upper lip, operability is high, a patient can hardly be interfered with, a doctor can more easily observe whether the mandible of the patient stretches forwards or not, and the patient is more easy to control.

Description

technical field [0001] The invention belongs to the technical field of dental mold-making instruments, and in particular relates to an improved complete denture maxillary primary mold tray. Background technique [0002] Complete denture impressions can be divided into open impressions and closed impressions according to the position of the mandible. When taking an impression of an opening, since it is the doctor who applies pressure to the tray, the doctor's operating experience and techniques are different, which may cause deformation of the mucous membrane, resulting in tenderness after the denture is worn. When making a closed mouth impression, the impression is made at the correct vertical distance in the center of the jaw, and the patient uses normal chewing pressure. This is a physiological, natural, and average pressure, not a doctor's impression. This kind of mastication pressure objectively shows the mucosal morphology in the functional state, and at the same time ...
