Description
Technical Field
The utility model belongs to an oral denture making tool, and particularly relates to a tray for a dental impression.
Background
Dentition loss refers to the loss of teeth from the entire arch without any natural teeth or roots, i.e., the loss of teeth from the entire mouth, also known as the edentulous jaw. The inexpensive and non-invasive traditional complete dentures (complete dentures) remain the most prominent way for the restoration of edentulous patients.
The complete denture is a repairing mode with strong technical sensitivity, and for patients with poor alveolar ridge conditions, the complete denture has the problems of poor retention, poor stability, chewing pain and the like, so that the functional recovery of the edentulous jaw patients, such as chewing, beauty, pronunciation, physiological stimulation and the like, is poor. In view of the great influence of the edentulous jaw on the physiology and the psychology of the patient, the good repairing effect is the guarantee of recovering the physical and mental health of the patient and improving the life quality. Therefore, improving the complete denture repair effect is a clinical difficulty faced by oral medicine and a social problem of aging society.
In the complete denture repair process, impression preparation and jaw position relation recording are two most central links. The conventional complete denture manufacturing steps are generally as follows:
1. the first visit of the patient: a preliminary impression is made, a preliminary model is cast and individual trays are made on this model.
2. The patient is treated for the second time: edge finishing was performed using individual trays, and a precise final impression was made with the final impression material and the final model (working model) was cast.
3. The third visit of the patient: making the upper and lower jaws on the final model
Holding in the palm, determining and recording the correct vertical and horizontal jaw position relation in the patient's mouth, and transferring the recorded jaw position relation record to
The racks are arranged in parallel.
4. The fourth visit of the patient: after the patient tries to arrange teeth in the mouth and adjusts the teeth satisfactorily, the complete denture is packed into a box, filled with glue, thermally treated and polished to complete the manufacture of the complete denture.
5. The fifth visit of the patient: the complete denture is tried on in the mouth of the patient.
The problems existing in the prior art are as follows:
1. in the open impression method adopted by the prior art, the muscular function modification made during impression taking is passive muscular function modification under the assistance of doctors, so that lip, cheek, tongue and muscle movement and the like during impression taking are greatly different from the actual functional state when a patient wears a complete denture, retention and stability of the denture are influenced, and the problems of easy falling, chewing pain and the like after repair are caused, thereby being a clinical difficulty faced by oral medicine.
2. In the prior art, the jaw relation can be recorded only after the steps of initial impression making and casting, individual tray making, final impression making and casting and the like are carried out, 4-5 times of medical visits of a patient are needed to be completed, and the time cost and the economic cost for the patient and family members to see the medical doctor are increased due to more medical visits.
3. In order to obtain an ideal closed impression to improve the complete denture repair effect, the prior art needs to perform multiple-link repair procedures including the steps of initial impression preparation and casting, individual tray preparation, final impression preparation and casting, tooth trial arrangement, denture completion and the like. Although the existing closed impression technology is improved for determining the step of the initial occlusion record, the steps of initial impression making and casting, individual tray making, final impression making and casting and the like cannot be reduced, the procedure is still complex, the time beside a chair for a doctor to occupy 4-5 hours is required, and the further improvement of the working efficiency of the doctor is hindered.
4. In the prior art, patients need to be matched for a longer time due to the fact that the patients have many times of treatment, complex procedures and complicated links. However, most of complete denture repairs are performed on elderly patients, and the tolerance is poor, so that complex procedures and complicated links easily cause the reduction of the fit of patients in key steps of impression preparation, jaw position measurement and the like due to poor physiological and psychological tolerance, thereby affecting the accuracy of the impression and the correctness of jaw position relation, and finally affecting the repair effect.
5. In the prior art, the repair procedure is complex, the links are complicated, the medical cost is increased, and the complete denture repair cost is further reduced and the economic burden of a patient is reduced on the premise of ensuring the repair effect.
