Description

A rubber dam clip for prefabricated crown restoration of children's second deciduous molars

technical field

The utility model relates to the technical field of medical appliances, in particular to a rubber dam clip for repairing prefabricated crowns of children's second deciduous molars.

Background technique

In the process of diagnosis and treatment in the Department of Pediatric Dentistry, for the safety and comfort of diagnosis and treatment, the rubber dam system is often used; the rubber dam is a rubber cloth that can separate the "water", isolate the teeth, and make the mouth The saliva and blood do not flow into the dentist's operation area.

The rubber dam isolation can well isolate saliva, blood or other tissue fluids, and obtain a clean and dry operating area; it reduces the possibility of patients frequently rinsing their mouths and talking to doctors during treatment; it avoids repeated replacement of wet-proof cotton rolls, saving treatment Time, improve efficiency; put the doctor in contact with the patient's saliva, avoid iatrogenic cross-infection of diseases such as hepatitis and AIDS, reduce cross-infection of the root canal system, and prevent the potential spread of infectious substances; retract soft tissues and protect oral tissues ;Rubber dam can provide a safe and comfortable guarantee to protect patients from inhaling or swallowing oral instruments, dental fragments, filling materials, drugs and irrigation fluid; rubber dam can provide a dry view and reduce the atomization of the mouth mirror, thereby improving Operational visibility.

Using a rubber dam can also protect the oral soft tissues, that is, the lips and tongue, from being cut by dental instruments, especially for children who often don’t listen to their tongues during treatment. If there is no rubber dam, it is easy to be cut by dental instruments. In addition, the rubber dam can prevent small instruments from falling into the mouth and accidentally swallowed into the esophagus or trachea, and reduce the cross-infection between patients and doctors.

During the use of the rubber dam, it needs to be clamped on the surface of the teeth by the rubber dam clips, so that the teeth are exposed outside the rubber dam, which is convenient for the dentist to diagnose and treat. However, for preschool children, the first permanent molars have not yet erupted. When performing crown restoration on the second deciduous molars, the doctor needs to prepare the mesial and distal teeth, especially the distal teeth. Some rubber dam clips cannot leave enough space for the distal tooth preparation, resulting in unsatisfactory treatment effects.

In order to solve the above technical problems, the utility model proposes a rubber dam clip for the preformed crown restoration of children's second deciduous molars.

Contents of the invention

The purpose of this utility model is to overcome the deficiencies of the prior art, and to propose a rubber dam clip for prefabricated crown restoration of children's second deciduous molars, which can prefabricate the second deciduous molars in children whose first permanent molars have not erupted. When the crown is restored, a space is reserved for the distal prepared tooth, so that the restoration effect of the prefabricated crown on the second deciduous molar can reach the expectation, and improve the safety of clinical treatment in pediatric stomatology. At the same time, the operation is simple, the difficulty of clinical operation is reduced, the operation time is shortened, and the improvement is improved. Efficiency; at the same time, improve the comfort of children's visits to the doctor, and alleviate the fear and rejection of children.

Preferably, the height difference between the highest point and the lowest point of the arc-shaped beak is more than 2 mm, so that the tip of the arc-shaped beak bends more than 2 mm below the gums, because the prefabricated crown needs to be in place about 1 mm below the gums, which is convenient for prefabrication. Crown try-on.

Specifically, the rubber dam clamp is installed on the rubber dam cloth, the rear rubber dam is arranged on the V-shaped wing, and at the same time, the rubber dam clamp is inserted into the through hole to separate the two clamping parts, and then the two clamping parts Socketed on the second deciduous molars, release the rubber dam forceps, and under the action of the resilience of the clamping arch, the two clamping parts are clamped on both sides of the second deciduous molars; then follow-up operations can be performed.

The beneficial effects of the utility model are:

The utility model arranges an arc-shaped beak on the front side of the clamping part, so that when the clamping part clamps the second deciduous molars, the arc-shaped beak bends more than 2 mm below the gums, thereby facilitating the try-on of the preformed crown.

The utility model arranges V-shaped wings on the rear side of the clamping part, so that the rubber dam is more than 2mm away from the distal second deciduous molars, and reserves enough space to facilitate the distal preparation of the second deciduous molars, and also facilitates prefabricated crowns. try it on.

The utility model provides anti-slip tooth lines on the inner side of the clamping part, so that the clamping part is more stable when clamping the second deciduous molars.

By adopting the above-mentioned scheme, the utility model can reserve space when the pre-formed crown of the second deciduous molar is restored to the child with the first permanent molar that has not erupted, which is convenient for the distal preparation of the second deciduous molar and the pre-formed crown. It can increase the clamping stability of the rubber dam clip on the second deciduous molars; make the restoration effect of the preformed crown on the second deciduous molars reach the expectation, improve the safety of clinical treatment in pediatric stomatology, and at the same time, the operation is simple and reduces clinical The operation is difficult, shortens the operation time, and improves the efficiency; at the same time, it improves the comfort of the children's treatment and alleviates the fear and rejection of the children.
