Description

Full-mouth rubber barrier for orthodontics

Technical Field

The utility model relates to the technical field of orthodontic treatment, in particular to a full-mouth rubber dam for orthodontic treatment.

Background

In the bonding process of orthodontic brackets, it is important to isolate saliva and keep tooth surfaces dry, cotton balls are often used for moisture isolation in clinic, but the moisture isolation effect of the method is poor, the bonding stability of orthodontic treatment brackets is affected, the mistaken swallowing and the mistaken suction of the cotton balls are easily caused, and the medical risk occurrence rate is increased.

The clinical rubber dam is widely applied to tooth filling and root canal treatment, effectively isolates saliva and avoids the error swallowing of instruments, but is only used for the tooth treatment of individual teeth or certain areas, the bonding of the upper and lower jaw full dentitions is required to be simultaneously bonded by the bracket bonding of the orthodontics, and the rubber dam suitable for full mouth use is required. Products of this type are lacking, so a full mouth barrier for orthodontics has been developed.

Disclosure of Invention

The utility model aims to provide a full-mouth rubber dam which is used in the bonding process of a full-dentition orthodontic bracket and can effectively isolate saliva from a tooth surface and wash liquor from oral tissues.

The technical scheme adopted by the utility model is as follows:

a full-mouth rubber barrier for orthodontics comprises an isolation part made of elastic materials, an annular opening part and an arched tooth pressing part, wherein the outer edge of the isolation part is connected with the opening part, and the tooth pressing part capable of pressing upper dentition and lower dentition is arranged between the isolation part and the opening part.

Further, the tooth pressing part comprises an upper bow-shaped piece and a lower bow-shaped piece which are approximately shaped with the upper dentition and the lower dentition, the two ends of the upper bow-shaped piece and the lower bow-shaped piece are correspondingly connected, and an angle is formed between the upper bow-shaped piece and the lower bow-shaped piece.

Further, the upper and lower bows are made of a wire-like material that is plastically deformable.

Further, the two ends of the upper bow-shaped piece and the lower bow-shaped piece are provided with hinging mechanisms.

Further, a transverse tongue pressing rod is arranged at the position of the lower bow-shaped piece close to the joint of the two ends. Further, a clamping groove is formed in the position, close to the connecting position of the two ends, of the lower bow-shaped piece, and a tongue pressing rod is arranged in the clamping groove.

Further, a fixing clip for fixing the isolation part at the tail end tooth is also included, the fixing clamp is a U-shaped metal clamping ring.

Further, the inside of the partition is marked with a reference site of the whole mouth tooth.

The utility model separates the upper lip and the lower lip from the tooth surface through the opening part, enlarges the operation visual field, separates the teeth of the whole mouth for orthodontic operation through the upper arch piece and the lower arch piece pressed on the upper dentition and the lower dentition, and physically separates saliva, flushing fluid, the tooth surface and oral tissues through the separating part, thereby reducing the pollution of the saliva to the tooth surface and avoiding the incorrect swallowing of the flushing fluid and the instrument.

Detailed Description

For a better understanding of the objects, structure and function of the present utility model, a full mouth barrier for orthodontic use according to the present utility model will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, a full-mouth rubber barrier for orthodontic treatment comprises an isolation part 1 made of elastic materials, an annular opening part 2 and an arched tooth pressing part 3, wherein the outer edge of the isolation part 1 is connected with the opening part 2, and the tooth pressing part 3 capable of pressing upper dentition and lower dentition is arranged between the isolation part 1 and the opening part 2. The elastic material can be elastic materials such as rubber cloth, plastic cloth and the like.

As shown in fig. 2 to 3, the tooth pressing portion 3 includes an upper arch piece and a lower arch piece which are approximately shaped as upper and lower dentitions, two ends of the upper arch piece and two ends of the lower arch piece are correspondingly connected, and an angle is formed between the upper arch piece and the lower arch piece. Since the tooth pressing portion 3 needs to have a certain angle. In this embodiment, the two ends of the upper and lower bows are integrally connected, and the whole tooth pressing portion 3 forms a member made of a wire-like material capable of plastic deformation, such as an iron wire. The opening angle is folded into a required opening angle by external force.

In an alternative embodiment, the upper and lower bows have hinge mechanisms 5 at both ends. The hinge mechanism 5 can be adjusted in angle or fixed in angle. This form of hinge mechanism 5 is conventional in the art.

In this embodiment, the lower bow member is provided with a clamping groove near the connection position of the two ends, and a transverse tongue pressing rod 4 is arranged in the clamping groove.

When in use, the fixing clamp 6 can be matched, as shown in fig. 4, A is a buccal surface view; b is tongue appearance; c is the far-middle aspect; d is the combined face view. The retainer clip 6 is a U-shaped metal clasp for the retention of the end dental dam around the buccal, lingual, distal cervical portion of the tooth. The inside of the partition 1 also needs to be marked with reference sites for the whole teeth.

It will be understood that the utility model has been described in terms of several embodiments, and that various changes and equivalents may be made to these features and embodiments by those skilled in the art without departing from the spirit and scope of the utility model. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the utility model without departing from the essential scope thereof. Therefore, it is intended that the utility model not be limited to the particular embodiment disclosed, but that the utility model will include all embodiments falling within the scope of the appended claims.
