Description
Technical Field
The invention belongs to the technical field of dental molding instruments, and particularly relates to an improved complete denture upper jaw primary mold tray.
Background
The complete denture impression can be divided into an open impression and a closed impression according to the position of the mandible during taking. When an open impression is prepared, a doctor presses the tray, and the skill of the doctor is different in operation experience, so that mucous membrane deformation can be caused, and pressure pain can occur after denture insertion. In the preparation of a closed impression, the impression is prepared at the median jaw position at the correct vertical distance, and the patient uses normal chewing pressure, which is physiological, natural and average pressure, rather than pressure applied to the patient by a doctor when taking the impression, the chewing pressure objectively represents the mucosa form in a functional state, and meanwhile, the patient actively performs muscle movements such as puckering, smiling, swallowing, biting and the like, so that the edge of the impression is matched with the movements of the muscles, thus the closed impression is the most accurate final impression.
The biggest technical key point of closed impression making is to make a waxy dike or a temporary denture in advance. The wax closing dykes are manufactured outside the mouth in advance, so that the upper wax closing dykes and the lower wax closing dykes cannot be aligned completely, and when the patient bites in the mouth, the correct bites can be determined only after the positions of the upper wax closing dykes and the lower wax closing dykes are adjusted repeatedly, so that the process is very time-consuming. Therefore, the initial occlusion relation can be prepared while the initial impression is prepared, the relatively accurate wax dental abutment can be prepared outside the mouth in advance, the time beside a chair can be reduced, and the method is very necessary and significant.
The prior art scheme is as follows:
1. the student produces an improved functional impression resin tray through the average anatomical values of the upper and lower jaws, and on the basis of the resin tray, resin occlusal dykes are produced through the average value at the positions similar to dentitions for recording the primary occlusion relationship.
The average anatomic values of the upper and lower jaws produced an improved functional impression resin tray on which resin and dykes were produced by average values at dentition-like locations for recording the preliminary bite relationship. However, the average value still deviates, and since the mandibular dyke is not open in the anterior mandibular region, there is a possibility that the mandibular protrusion is guided when recording the bite relationship, and thus the erroneous bite relationship is recorded.
2. A functional adsorption denture (BPS) is used for preparing a preliminary jaw relation by using a median dentition tray and silicone rubber during initial impression.
Functional adsorption dentures (BPS), when the primary occlusion relationship is made with an orthodontic tray, the primary perpendicular distance that may be obtained is ultimately lower due to the inability of the patient to control the force because of the softer silicone rubber texture. And the median dentition tray with the silicone rubber is large in size and is placed in the mouth, so that a patient cannot easily perform mandibular movement according to the instruction of a doctor.
3. And when the functional digital complete denture (FSD) with easy adaptability is used for preparing an initial impression, the vertical distance and the horizontal relation of occlusion are directly determined by adding red paste to the upper jaw adjustable aluminum tray.
When the functional digital complete denture (FSD) with easy adaptability is used for preparing the primary occlusion relationship, red paste is directly used for determining the occlusion vertical distance and the occlusion horizontal relationship, and as the red paste is put on the whole vertical distance, a patient needs higher matching degree when determining the jaw position relationship, otherwise, the record of the occlusion relationship of the patient can be interfered.
Disclosure of Invention

Still more preferably, a plurality of overflow drain holes are also provided on the outer side of the dike. The overflow hole is convenient for the excessive impression material to overflow from the overflow hole after the maxillary impression is prepared, reduces the formation of bubbles on the tissue surface of the impression, and prevents the impression from demoulding.
The beneficial effects of the invention are as follows:
when the upper jaw primary mould tray is used for preparing the impression, the initial dental occlusion relation can be prepared at the same time, the upper jaw primary mould tray is provided with a dental occlusion dike and a dental occlusion dike similar device in the oral cavity of a human body, and the upper jaw primary mould tray is provided with a retention groove; the handle direction of the tray is consistent with the upper jaw middle incisor direction, and the length and the position of the tray can not interfere with the movement of the upper lip. After the maxillary impression is prepared, excessive impression material can overflow from the overflow holes, so that the formation of bubbles on the tissue surface of the impression is reduced, and the impression is prevented from demolding. Resetting the upper jaw impression to the inside of the mouth after the upper jaw impression is prepared, placing injection type silicon rubber or organic mixed silicon rubber on the top of the dental alveolus ridge of the lower jaw, and stopping after the middle of the patient is ordered to be occluded to a proper vertical distance; the material enters the retention groove of the dental abutment, which is beneficial to the fixation of the material on the maxillary dental abutment, and after the material is solidified, the maxillary impression and the primary jaw position relationship can be obtained. The method is directly bitten on the top of the mandibular alveolar ridge, the operability is stronger, the patient is relatively not easily disturbed, and a doctor can easily observe whether the mandible of the patient extends forward or not. In addition, only part of the silicone rubber is needed to be placed for recording in the whole vertical distance, and the patient is easier to control because the whole occlusion height is not the whole occlusion height.
