Description
Technical Field
The invention belongs to the technical field of oral occlusion relation recording, and particularly relates to a method for recording occlusion relation in a static state.
Background
One of the principles that needs to be clarified in the repair treatment is to establish a correct occlusion relationship under a correct jaw position relationship. Jaw position refers to the positional relationship of the lower jaw relative to the upper jaw, and occlusion refers to the contacting relationship of the upper and lower teeth at a certain jaw position. According to the principle of science, the prosthesis not only restores the form of the missing tooth, but also ensures that the occlusion and the jaw position are coordinated so as to ensure that the oromandibular system consisting of the occlusal joint, the temporomandibular joint, the nerve and the masticatory muscles can achieve the functional reconstruction in the true sense. Therefore, establishing a physiologically logical relationship and correctly recording is a prerequisite for successful repair.
Jaw relation records (recording maxillofacial and dental relationships) refer to the determination and recording of the jaw position relation at an appropriate height of the patient's face 1/3 and with the lateral condyles at physiological posterior positions of the mandibular joint concavity, so that the total denture is used to reconstruct the neutral relation of the edentulous patient in this relationship of the maxilla and mandible. When natural dentition exists, the upper dentition and the lower dentition are closely contacted together, the anterior teeth are normally covered and covered, the posterior occlusal surfaces are in a contact relationship of tip and socket staggering, and the upper jaw and the lower jaw are in the most extensive contact position (the normal jaw position). When the natural dentition is lost, the central jaw position is lost, the lower jaw does not have the support of the dentition and the locking of the cusp, the lower jaw can move to various positions, and the lower one third distance of the lower part of the front stretching and combining surface of the lower jaw is shortened. For an edentulous patient, the only stable reference position for the maxillomandibular relationship is the neutral relationship position. Thus, restoration of the physiological jaw position and bite relationship is determined and correctly recorded in the physiological posterior position of the joint at a height of one third below the appropriate plane, i.e., the neutral relationship position.
The repair of the single-jaw complete denture is difficult, for example, the change of the jaw arch of the edentulous jaw is not coordinated with the involution of the dental arch, which brings difficulty to the occlusion design of the denture. And because unstable factors such as loose teeth, edentulous areas and the like possibly exist in the edentulous occlusal arch, the complete denture can not record correct and stable occlusion relationship, and the repair difficulty is increased. Therefore, the occlusion relation record of the single-jaw complete denture repair needs to correctly reflect the situation of the involution dentition and correctly record the jaw position relation and the occlusion relation of the complete denture.
In oral clinical operation, when the occlusion relation of a single-jaw complete denture is obtained in a patient, most occlusion conditions can be obtained by using a conventional wax biting method. However, the involution of the edentulous jaw contains two or more loose teeth (the loose teeth can not be pulled out due to subjective reasons and objective reasons of a patient), and when the patient bites wax, the loose teeth are displaced due to the force of the wax, so that the occlusion is unstable; for patients with anterior or posterior edentulous regions (especially, the posterior area), the patients tend to concentrate their attention on the edentulous region, which makes the occlusion shift to one side, resulting in occlusion errors. The continuous and repeated recording of failed wax bites also can cause unpleasant emotion to the patient.
In the past, physicians have used red wax or silicone rubber bite registration wax to make one impression taking, i.e., to record a dynamic bite registration. However, because of the unstable factors in the mouth of the patient, the patient is difficult to bite to the ideal jaw position relationship under the guidance of the doctor and is easy to be interfered, so that the satisfactory bite record is difficult to obtain, and the problems are not solved. Firstly, the technical requirements on doctors are high, and the occlusion condition under the condition that unstable factors exist in the mouth of a patient, such as occlusion deviation, jaw relation deviation (not being occluded to a central relation position) and the like, can be correctly judged in the occlusion dynamic process. Second, it is difficult for the physician to engage the correct jaw relation on his or her own, and even more difficult for the patient. In a certain learning class in Zhejiang, some doctors with abundant clinical experience can repeatedly generate occlusion deviation and cannot correctly record occlusion relation in the process of experiencing dynamic occlusion recording wax.
Disclosure of Invention
The invention aims to provide a method for recording occlusion relation in a static state, which solves the technical problem that accurate occlusion relation is difficult to obtain due to unstable occlusion relation in the prior art. In order to achieve the purpose, the method adopts the following technical scheme:

(2) taking the final positive relation bit occlusion relation record: and then positioning the combined support in the mouth according to the mark points in the first step, ordering the patient to perform median occlusion to the median relation position in the first step, injecting the elastic impression material on the base support corresponding to the wax levee removed in the first step on the basis of the primary median relation position occlusion relation record in the state of the static median occlusion relation, after the elastic impression material is solidified and attached to the base support, ordering the patient to open the mouth, and taking out the combined support to obtain the final occlusion relation record relation.
Further, the unstable region: the dental arch is divided into three areas, namely an anterior dental area and two posterior dental areas, and the areas contain two or more loose teeth or missing teeth.
Further, when the preliminary and final occlusion relations are recorded, the occlusion relations should be kept still, i.e. kept in a stable neutral relation position, so as to obtain a consistent occlusion relation.
Further, the impression material tightly fills the gaps between the base and the involution and forms seamless connection with the adjacent wax dikes.
Further, the elastic impression material is a silicon rubber impression material.
Compared with the prior art, the invention has the following beneficial effects:
the invention adopts the method of recording the occlusion relation under the static state to make the occlusion record of the unstable area of the base clear, can completely expose the unstable area, and firstly extracts other stable area forms to obtain support. And then, the printing film material with good fluidity is slowly injected into the base support under the direct vision, so that the unstable area is completely and clearly copied on the combined support under the conditions of no pressure and no displacement, the occlusion error caused by the interference of unstable factors can be avoided, the deviation of loose teeth and the occlusion stress concentration of the tooth-free area are prevented, and the occlusion recording relation under the physiological state can be conveniently and accurately reflected. The occlusion relation record taken out in this way is used for manufacturing the complete denture, the recovery of the chewing function of a patient is better reflected, the comfort level is higher, the number of times of the return visit is reduced, and the satisfaction degree is high. The technology accurately reproduces soft and hard tissue anatomical structures of unstable areas (such as loose teeth and edentulous areas) in physiological states, is beneficial to recording occlusion relations of the unstable areas, is convenient for doctors to operate, can be applied to people with unstable occlusion relations or poor occlusion relations caused by other reasons, obviously improves the repair effect of the false teeth, and is worthy of clinical popularization.
