Description
Technical Field
The utility model relates to an oral medical instrument, in particular to an individual tray for preparing a pressure impression of missing free end dentition.
Background
The individual tray is widely applied in the oral field, and the complete denture can not meet the individual dental arch and alveolar ridge conditions of a patient due to the fact that the oral morphology and the alveolar ridge conditions of the patient are different in the complete denture repair, and the accuracy of the impression can be improved only by manufacturing the individual tray to prepare the secondary impression, so that the individual difference of the patient can be met, and the complete denture repair effect is guaranteed.
For removable partial dentures with free-end dentition defects, the support is provided by a special mixture of teeth and mucous membraneA support mode. The free end dentition defect refers to the defect of the back teeth on one side of the dental arch, the far middle is a free end, when only one back teeth on one side is lost, the defect is called as the defect of the free end on one side, and when the back teeth on two sides are all lost, the defect is called as the defect of the free end on two sides, because the free end teeth and the mucous membrane have obvious allowability difference, the mucous membrane and the denture base do not stick to each other after the free end removable local denture is used for a period of timeThe phenomenon of (2) causes food retention, false tooth loosening and also can cause certain stress damage to natural teeth. To solve this problem, pressure impression techniques are generally used clinically in the free-end edentulous area, which can be accurateRecording the shape of the mucous membrane under the functional pressure state, overcoming the defect that the traditional impression technology can only prepare surface shape, reducing the allowance difference between the tooth and the denture base, and ensuring that the base is kept attached to the mucous membrane under the functional state

Detailed Description
The utility model discloses an individual tray for preparing free end tooth row lacks loss pressure nature die, including tray body 1, tray body 1 includes the natural tooth district tray 11 of surplus and lacks tooth district tray 12, a serial communication port remaining stings of natural tooth district tray 11The surface is provided with a through hole 13 for extending the residual natural teeth out of the individual tray, and the tray 12 of the edentulous area is provided with an occlusionAnd a dike 14.
In this embodiment, an on-bite dentition is provided that allows for the creation of a free end defectIndividual trays of pressure impressions in the state in which they are to be taken by the wearerThe pressure impression in the state needs to design individual trays so that the wearer can completely bite natural teeth and jaw teeth when wearing the individual trays
In this embodiment, the top of the natural teeth is exposed by forming the through-holes 13 in the tray 11 for the remaining natural teeth so that the remaining natural teeth pass through the through-holes 13 and normally bite the teeth of the jawThereby leading the wearer to be capable of remaining natural teeth and the pair when wearing the individual trayBite of teeth
In this embodiment, the dentition and the biting of the teeth of the jaw are performed in the absence of teethThen, in order to extract the pressure impression of the mucous membrane tissue in the edentulous area, the tray for the edentulous area is provided with a biteThe dike 14, as shown in fig. 1, bites intoThe dike 14 is approximately cuboid, one surface of the cuboid is attached to the tray of the edentulous area and is integrally formed with the tray of the edentulous area, and the bite is arrangedThe purpose of the levee 14 is to bite by injection thereinThe silicone rubber jaw-biting embankment and the natural opposite jaw teeth can be centrally occluded, and pressure is transmitted to the surface of the tray tissue to form the pressure impression.
In this embodiment, a specific tray can be shown in fig. 1, and the specific tray is suitable for making a model of dentition with both free ends missing, that is, two occlusion embankments are arranged on the specific tray and are respectively used for making an impression of oral mucosa of the two missing tooth areas; the individual tray, which is also suitable for modeling dentition with missing free ends on one side, can be designed according to the specific situation of the dentition to be modeled, as shown in fig. 2.
Therefore, the steps of using the individual trays provided in this embodiment are:
after injecting impression materials on the tissue surface of the individual tray and the fenestration position in the individual tray, putting the individual tray on the dentition of the impression to be made as shown in figure 3; biting on individual traysBite of dikeOn-face injection biteAfter the silicone rubber material was recorded, a median bite was performedUp to the impression material and biteAfter the silicone rubber material was recorded to solidify, the individual tray was removed and a new pressure impression was obtained.
As shown in fig. 1-2, to prevent individual traysPrying and rotating are formed after the dental impression tray is worn in the mouth, so that the accuracy of the pressure impression is influenced, and a tray part corresponding to a natural tooth support recess is provided withThe support bracket 17 is provided with a support bracket 17,the number of the rests 17 can be determined according to the dentition of the impression to be taken, at least one of them being provided in order to be able to pass after the individual tray has been placed in the mouthThe rest 17 is in place in the natural dental rest depression, acting as a resting stop and reference point when the individual tray is worn,the rest 17 being smoothly positioned in correspondence with the natural toothRest in the fovea without affecting the median biteThe individual trays can obtain stable dead points without swinging and prying, ensuring the precision and accuracy of impression making, as shown in figures 1-2,the lugs 17 are located inside the tray 11 of the remaining natural dental area.
As shown in fig. 1-2, for facilitating bitingBite by injection on leveeRecording silicone rubber material capable of adhering to biteOn the surface of the dike, preventing biting in the center of executionAt that time, the bite has not solidified yetRecording the movement of the silicone rubber material in the oral cavity to ensure bitingRecording the positional stability of the Silicone rubber Material in bitingThe levee 14 is provided with a recess 15 so that an accurate impression of the edentulous area is obtained.
As shown in fig. 1-2, for facilitating bitingRecording that the silicone rubber material can be uniformly adhered to the biteOn the surface of the bank, on which said biteThe dike 14 is provided with a plurality of parallel grooves 15.
Optionally, the height of the residual natural tooth area tray 11 is 1/3-1/2 of the crown height of the residual natural tooth.
To enable the patient to perform a complete biteWhen the windowing treatment is carried out, the height of the individual trays wrapping the natural teeth is further reduced, so that the natural teeth can be fully exposed to realize complete occlusion of the jaw teethThe bite of the tray 11 of the remaining natural tooth area is cut offFlour and biteThe height of the tray 11 of the remaining natural dental area after the two facing surfaces are connected is 1/3-1/2 of the crown height of the remaining natural tooth.
Optionally, a plurality of overflow holes 16 are opened on the tray body 1.
As shown in fig. 1-2, since the light silicone rubber impression material needs to be injected into the inner side of the individual tray during the use of the individual tray, when the individual tray is worn on the dentition, the light silicone rubber impression material which is not solidified yet is extruded from the inlet of the individual tray due to the extrusion action of the individual tray and the dentition, which affects the accuracy of the obtained impression, a plurality of overflow holes 16 are provided in the tray body 1 for discharging the light silicone rubber impression material from the overflow holes 16 when the individual tray is worn.
Optionally, the individual tray further comprises a tray handle 2 connected to the tray body 1.
As shown in fig. 1-2, in order to facilitate the worker to take a particular tray, a tray handle 2 is connected to the tray body 1, and the fixed end of the tray handle 2 is fixedly connected to the middle of the tray body 1.
