Description
Technical Field
The invention relates to a disposable anti-demolding lower jaw tray, and belongs to a tool for preparing an impression in an oral cavity.
Background
In oral treatment, the preparation of an impression in the oral cavity is often needed, such as fixing, movable repairing, implant denture repairing and the like in the oral cavity repairing treatment, model analysis in the oral orthodontic treatment, model registration and the like.
The accurate impression is the basis of all restoration treatments and also the guarantee of the invisible correction accurate treatment.
Although the development of digital impression technology is changing day by day, because the scanner is expensive and not convenient for clinical popularization, the clinical treatment such as daily outpatient service restoration still adopts the tray and impression material to prepare upper and lower dentition impressions, and then prepares a restoration or an appliance after pouring a model, and the accuracy of the impression determines the accuracy of a plaster model, and only an accurate model can prepare a high-quality restoration and an appliance.
The stainless steel trays which can be sterilized at high temperature are generally used clinically, and are divided into two types of trays with holes and without holes, the trays with the holes are arranged at the handle parts of the trays, namely, the tooth cutting areas of the trays, in order to enhance the retention and the strength, the retention holes are not usually arranged, the impression material has higher pressure when an impression is made and is thinner, and when the impression material is finally dislocated in the mouth, the negative pressure is higher, so that the impression material is easy to separate from the trays, namely, the demoulding phenomenon appears; the nonporous tray needs a tray adhesive to strengthen the adsorption of the impression material and the tray in order to prevent demoulding when a fine silica gel impression or a polyether impression is prepared; the tray adhesive belongs to a chemical preparation and has pungent smell; the disposable tray is also adopted clinically, so that clinical cross infection is avoided, but the retention of the impression material is increased by simply adopting a tray punching mode, the mechanical locking force between the impression material and the tray is insufficient, the demoulding phenomenon in impression preparation is often caused, the working efficiency and the preparation quality of a restoration body are influenced, and certain influence is caused on clinical work.
Disclosure of Invention
In order to solve the defects and shortcomings of the prior art, the invention provides a disposable anti-demolding lower jaw tray which can realize good mechanical retention and strength of an impression material during impression taking, avoid separation of the impression material and the tray and ensure high accuracy of an impression. Meanwhile, the low use cost is ensured.
The invention carries out mechanical retention design of the bottom and the side wall of the disposable mandible tray again; firstly, a T-shaped retention device is added in the middle of two sides of a cheek tongue in the side wall of the lower jaw tray, and the edge of the tray is designed into an inward-rolling locking retention structure; the tray bottom that holds the dental arch is the design of two bottoms, increased die position fixing hole windowing on the inner bottom, be convenient for the die material from the centre through flow go into in the maintenance chamber intermediate layer between the outer sole, the outer sole of two bottoms is totally closed, there is not die position fixing hole, maintenance chamber intermediate layer height between the inside and outside both sides is about 2.0mm, there is thin columnar support column maintenance device in the centre, the exhaust hole has been designed around the maintenance chamber intermediate layer lateral wall, overflow of air when being convenient for the die material to flow in and be full of the intermediate layer, the intensity and the thickness of die material have been guaranteed, and realize good mechanical maintenance. Meanwhile, the design of the double-bottom tray increases the strength of the tray and is not easy to deform. The design of the impression retaining hole on the side wall of the tray is increased, the overflow and the locking strength of the impression material are convenient, and the bottom edge is an inward-rolling locking retaining structure. The tray handle is positioned in the center of the outer bottom of the horseshoe-shaped tray and extends out, so that the retention and the adsorption force of the impression material at the position are not influenced, the impression material is ensured not to be separated from the tray finally, the tight combination is not deformed, and the accuracy is good.
The disposable anti-demolding lower jaw tray is made of high-strength recyclable environment-friendly materials such as plastics, composite materials, printing resin materials and the like, preferably high-strength polyvinyl chloride (PVC) or Polyethylene (PE), and is low in application cost.
The technical scheme of the invention is as follows:
disposable anti-stripping lower jaw tray, including tray handle 1, tray lateral wall 2, impression position fixing hole 3, "T" type strip position fixing device 4, tray inner bottom 5, tray outer sole 6, intermediate layer exhaust hole 7, intermediate layer support column 8 and tray inside wall 9, wherein:
the tray handle 1 is positioned at the top end of the horseshoe-shaped tray;
the bottom of the lower jaw tray is in an arc shape with the rear part slightly protruding inwards;
a plurality of interlayer exhaust holes 7 are formed in the interlayer side wall between the tray inner bottom 5 and the tray outer bottom 6;
a plurality of impression retaining holes 3 are distributed on the inner side wall surface and the outer side wall surface of the lower jaw anti-demolding tray, and a U-shaped groove for accommodating dentition is formed between the outer side wall 2 of the tray and the inner side wall 8 of the tray; a surrounding T-shaped strip fixing device 4 is respectively arranged at the inner center of the inner and outer side walls of the groove, die fixing holes 3 are distributed at the bottom of the U-shaped groove, the bottom of an interlayer between a tray inner bottom 5 and a tray outer bottom 6 is fully open, and a columnar interlayer supporting column 8 is arranged in the middle for supporting;
the horizontal surface of the lower jaw tray is in a horseshoe shape;
the edge of the tray is inward rolled and inclined towards the side wall;
the tray is made of polyvinyl chloride (PVC) or Polyethylene (PE);
the U-shaped groove is in a trapezoid shape with a narrow lower part and a wide upper part.
The invention has the beneficial effects that: the lower jaw tray adopts the design of double bottom layers at the bottom of the tray for accommodating dental arches, the retention devices are additionally arranged on the inner side wall, the outer side wall and the edge of the lower jaw tray, and the common problem that the disposable plastic tray is easy to demould is fundamentally solved through the locking retention of the mechanical structure of the double bottom layers, the clinical application of chemical agents such as tray adhesives is avoided, the possible cross infection of patients in the preparation of impressions is prevented, the accuracy and the clarity of the repaired impressions are ensured, and the high-efficiency and accurate clinical repair treatment and the like are facilitated.
