Description
Technical Field
The invention relates to a medical appliance, in particular to a dental clearance retainer implanted in an oral cavity.
Background
The primary teeth of children are lost early due to various reasons, and a missing tooth gap is left in the primary teeth columns, and the primary teeth on two sides of the gap incline to the gap side due to the loss of support; the jaw teeth can be gradually stretched due to no normal tooth blocking, so that the dentition disorder can be finally caused, and the subsequent eruption of the permanent teeth is blocked.
The gap retainer is used for keeping the teeth lost gap and keeping the dentition form stable. Can solve the problem caused by the early loss of the deciduous teeth.
Although the existing clearance retainers are various, the existing clearance retainers are often troublesome to manufacture, simple in process, unstable in fixation and poor in clinical treatment effect due to a plurality of concurrent dental diseases. For example, figures 5 and 6 illustrate a prior art gap retainer comprising a band that fits over the distal tooth (the tooth to the left of the missing tooth) and a loop of wire that is in the position of the missing tooth and that slightly contacts the proximal tooth (the tooth to the right of the missing tooth).
In addition, the existing gap retainer needs to be manufactured one-to-one according to the dentition form of a patient, the process is complicated, the main components need to be bent manually, and the precision and the comfort level depend on personal experience and technology of doctors. The movable gap retainer is manufactured by using self-setting resin, peculiar smell exists after the movable gap retainer is manufactured, the resin has aging deformation phenomenon in the use process, the size is large, the movable gap retainer is inconvenient to take off and wear, and children often refuse to wear the movable gap retainer; the wire ring type retainer needs to wear a belt ring, the belt ring is large in volume and weight, strong in foreign body sensation and poor in comfort, gum is easy to stimulate, secondary caries is easy to occur around the belt ring, falling is easy to occur in the correction process, and a wire ring welding point formed by bending steel wires is easy to crack.
Disclosure of Invention
The invention aims to solve the problems that the process of the deciduous teeth gap retainer is complex, the doctor experience and technology are seriously depended, the wearing is uncomfortable, and the like.
The technical scheme adopted for achieving the purpose of the invention is that the universal semi-wire ring type gap retainer is characterized by comprising a supporting rod, a base, a sliding sleeve and a set screw.
One surface of the base is an adhesive surface B, and the other surface of the base is connected with the sliding sleeve.
The sliding sleeve is provided with a sleeve hole and a threaded hole. The sleeve hole is a through hole penetrating through two ends of the sliding sleeve. One orifice of the threaded hole is formed in the wall of the sleeve hole, and the other orifice is formed in the outer wall of the sleeve hole.
The support rod is sequentially divided into a first section, a second section and a third section.
The first section of the support rod penetrates through the trepanning. The second section of the support rod is bent towards the direction of the base.
The third section of the support rod is bent towards the direction of the base. The third section of the support rod is a contact surface A on one side of the third section, which is away from the base.
The set screw is screwed into the threaded hole.
Further, the support rod, the base and the sliding sleeve are made of titanium alloy.
Further, the bonding surface B is provided with staggered scores.
The technical effects of the invention are undoubted:
1) The titanium alloy is used as the main body material of the device, so that the device has small volume and light weight, and the problem of strong foreign body sensation and poor comfort level is solved; the device has no peculiar smell;
2) The device is adhered to the surface of the teeth, has small contact area with the teeth, and can not stimulate gum mucous membrane and generate secondary caries;
3) The device is connected with the rod type by adopting the slide way, the straight screw is fixed, the length adjustment and interception can be carried out according to the gap size, one-to-one manufacturing is omitted, the device is used without taking a model, the precision is good, and the bending is not required;
4) The slideway and the base are cast and molded, so that the problem of later cracking does not exist.

In the figure: the tooth support comprises a support rod 1, a first section 101, a second section 102, a third section 103, a base 2, a sliding sleeve 3, a set screw 4, a sleeve hole 301, a threaded hole 302, a contact surface A, an adhesive surface B, a far-middle side tooth 5, a near-middle side tooth 6, a belt ring 7, a wire loop 8 and a missing tooth position E.
Detailed Description
The present invention is further described below with reference to examples, but it should not be construed that the scope of the above subject matter of the present invention is limited to the following examples. Various substitutions and alterations are made according to the ordinary skill and familiar means of the art without departing from the technical spirit of the invention, and all such substitutions and alterations are intended to be included in the scope of the invention.
Referring to fig. 1 and 2, a universal semi-wire loop type gap retainer includes a support rod 1 made of medical titanium alloy material, a base 2, a sliding sleeve 3 and a set screw 4.
Referring to fig. 3, the base 2 is a rectangular or other metal plate, one surface of which is an adhesive surface B, and the other surface of which is connected to the sliding sleeve 3. In the embodiment, the adhesive surface B is provided with staggered scores as shown in fig. 4, and the adhesive surface B can be fixed at 1/3 of the buccal side of the crown of the tooth at the far side of the gap by using an adhesive special for dentistry.
Referring also to fig. 3, the sliding sleeve 3 is an elongated metal block, and the lower surface of the sliding sleeve is fixed on the base 2. The sliding sleeve 3 is provided with a sleeve hole 301 and a threaded hole 302. The sleeve hole 301 is a through hole (extending in the length direction of the sliding sleeve 3) extending through both ends of the sliding sleeve 3. One orifice of the threaded hole 302 is on the wall of the sleeve hole 301, and the other orifice is on the outer wall of the sleeve hole 301.
The support bar 1 is divided into a first section 101, a second section 102 and a third section 103 in sequence.
The first section 101 of the support rod 1 extends through the trepanning 301. The second section 102 of the support rod 1 is bent towards the base 2 and is at an angle α to the first section 101 of the support rod 1.
The third section 103 of the support bar 1 is bent towards the base 2 and is beta deg. to the second section 102 of the support bar 1.
It should be noted that the third section 103 of the support rod 1 extends into the gap left by the missing tooth, and the side of the third section 103 of the support rod 1 facing away from the base 2 is a contact surface a. The contact surface A is slightly contacted with 1/3 of the distal crown surface of the mesial tooth without subjecting the contacted tooth to additional thrust.
In an embodiment, the angles of α ° and β ° may be thermally bent according to the actual situation. For example, in the figure, α° +β° =270°, α° =150°, β° =120 degrees.
In an embodiment, after the set screw 4 is screwed into the threaded hole 302, the set screw 4 is tightened to compress the first section 101 of the support rod 1 in the sliding sleeve 3. The length of the whole device is fixed, the length of the gap between two teeth is reliably maintained, the corresponding fine adjustment can be carried out according to the change of the gap length caused by the growth change of the dentition, and the permanent teeth at the corresponding positions can be removed after eruption.
