Description
The utility model discloses a kind of disposable use tray for buccal impression, belong to type medical instrument for dental use
Technical field.
Tray for buccal impression is that odontologist is used for holding impression material when having a denture made for the patient, puts into patient oral cavity impression and obtains a kind of instrument of dental impressions.Clear accurate dental impressions is to guarantee the basis of dental prosthesis quality and crucial, for this reason, will obtain the die of the upper and lower tooth of patient when having a denture made simultaneously, so as dental prosthesis can with the accurate interlock of upper and lower tooth.The present tray for buccal impression of making of metal material that mostly is in hospital's employing, the tray for buccal impression of this metal can be repeatedly used, but has following defective, if sterilization is not thorough, cause easily the patient cross infection, spread disease, as hepatitis, acquired immune deficiency syndrome (AIDS) etc.In addition, the tray for buccal impression of metal combines insecure with impression material, and the demoulding easily influences the accurate of model.Also useful plastic production tray for buccal impression on market at present, but its structural design is unreasonable, can not adapt to human oral cavity dissect physiology structure, can not combine firmly with impression material simultaneously, and easy deformation, thereby cause die type accuracy relatively poor.
The purpose of this utility model provides a kind of disposable use tray for buccal impression, and its reasonable in design combines firmly with impression material, and the impression model is accurate, can avoid patient's cross infection simultaneously, protection patient body health, and simple for production, cost is lower.
The designed disposable use tray for buccal impression of this utility model comprises upper jaw pallet and lower jaw pallet, and they are made of shape of a hoof tray slot, have through hole in the tray slot of upper jaw pallet and lower jaw pallet.
Through hole in the described tray slot is a bellmouth, and the through hole port on the tray slot inner surface is the small-bore port, and the through hole port on the tray slot outer surface is the large aperture port, the through hole cross section be shaped as circular port, strip hole or square opening.
Have blind hole on the inner surface of described tray slot, described blind hole is a tapered blind hole, and the blind hole upper port is the small-bore port, and the blind hole lower end is the large aperture port, and blind hole is shaped as circular port, square opening or strip hole.
The decorative pattern that on the inner surface of described tray slot, has projection.
Described decorative pattern be shaped as X-shaped decorative pattern, undulations, grid decorative pattern, straightway decorative pattern, annular decorative pattern or sparrow pecked.
The lateral wall of the tray slot of described upper jaw pallet forms by upwardly extending lip buccal wall with the corresponding curved wall of upper jaw oral mucosa opisthotonos line, the tray slot medial wall of upper jaw pallet fuses, median rise, common formation and alveoli dentales maxillae ridge, the corresponding curved surface in palate chamber; The lateral wall of the tray slot of lower jaw pallet forms by the lip buccal wall of downward extension with the corresponding curved wall of lower jaw oral mucosa opisthotonos line, and the medial wall of the tray slot of lower jaw pallet forms by the tongue wall of downward extension with the corresponding curved wall of lingual frenum incisura.
Have handle on upper jaw pallet and lower jaw pallet, the front end of handle is connected with the bottom surface of tray slot, and the rear end bending of handle is at two vertical strengthening ribs of handle bending place band.
Both sides, junction, bottom surface at handle front end and tray slot have the plane reinforcement.
Described upper jaw pallet and lower jaw pallet are made with ABS resin.
Be mixed with degradable master batch in ABS resin, the weight of degradable master batch is 5～15% of used ABS resin weight.
The designed disposable use tray for buccal impression of this utility model has following advantage:
1. rational in infrastructure, combine firmly with impression material, the impression model is accurate.The designed disposable use tray for buccal impression of this utility model is rational in infrastructure, have and the close curvilinear sidewall of oral mucosa opisthotonos line in the both sides of tray slot, can make disposable use tray for buccal impression correctly put into the oral cavity, complete covering alveolus obtains correct dental impressions.In tray slot, have through hole, blind hole and decorative pattern, impression material is combined with tray slot firmly, the die difficult drop-off, thereby die is accurate, indeformable.
2. safety and sanitation prevent cross infection.The designed disposable use tray for buccal impression of this utility model adopts ABS resin to make after injection mo(u)lding, makes easily, and cost is lower, adopt disposable occupation mode, do not reuse, thereby safety and sanitation, avoid cross infection, improved medical safety.
3. the designed disposable use tray for buccal impression of this utility model adopts ABS resin to make; in ABS resin, add degradable master batch; within a certain period of time; ABS resin will be decomposed voluntarily; thereby use the depleted disposable use tray for buccal impression in back can not cause environmental pollution, help environmental conservation.The intensity height of ABS resin is not yielding with the tray for buccal impression that it is made in addition, helps improving the die precision.Can use flame heat with the disposable use tray for buccal impression that ABS resin is made, repair after making it softening, make tray for buccal impression be applicable to special instructions for use, increase the scope of application of disposable use tray for buccal impression.
Fig. 1 is the structural representation of upper jaw pallet.
Fig. 2 is the structural representation of lower jaw pallet.
Fig. 3 is the A-A profile of Fig. 1.
Below in conjunction with drawings and Examples this utility model is elaborated.
Embodiment 1
It is shown in Figure 3 that the structural representation of the described disposable use tray for buccal impression of present embodiment sees that Fig. 1 arrives.
Disposable use tray for buccal impression includes upper jaw pallet and lower jaw pallet, and they are made of horseshoe-shaped tray slot 1 and 2.Strip through hole 3 is arranged in tray slot 1 and 2, and strip through hole 3 is a bellmouth.Through hole port on the inner surface of tray slot 1 and 2 is the small-bore port, and the through hole port is the large aperture port on the tray slot outer surface, and its section shape is seen shown in Figure 3.Have blind hole 4 on the inner surface of tray slot 1 and 2, blind hole 4 is a tapered blind hole, and the upper end of blind hole 4 is the small-bore port, and the lower port of blind hole 4 is the large aperture port.The X-shaped decorative pattern 5 and the sparrow pecked 6 that on the inner surface of tray slot 1 and 2, also have projection.
The two ends of the lateral wall 7 of the tray slot 1 of upper jaw pallet are upwardly extending lip buccal wall 8, and the middle part is and the corresponding curved wall 9 of upper jaw oral mucosa opisthotonos line that they link to each other and form lateral wall 7.The medial wall 10 of tray slot 1 is connected as a single entity, median rise, and its shape is and alveoli dentales maxillae ridge and the corresponding curved surface of palate cavity shape, so that alveolar ridge in the complete covering of tray slot 1 energy.
The two ends of the lateral wall 11 of the tray slot 2 of lower jaw pallet are the lip buccal wall 12 that extends downwards, and the middle part is and the corresponding curved wall 13 of lower jaw oral mucosa opisthotonos line that they link to each other and form lateral wall 11.The two ends of the medial wall 14 of tray slot 2 are the tongue wall 15 that extends downwards, and the centre is and the corresponding curved wall 16 of lingual frenum incisura that they link to each other and form medial wall 14, so that alveolar ridge under the complete covering of tray slot 2 energy.
