Description

Rubber dam clamp suitable for many serious tooth body defects suffer from tooth

Technical Field

The invention relates to the field of rubber barrier clamps, in particular to a rubber barrier clamp suitable for multiple seriously damaged teeth.

Background

In the process of oral treatment, the rubber dam can isolate the affected teeth from other oral structures, prevent saliva, blood and other tissue fluids from polluting a treatment area, and protect other parts of the oral cavity. The rubber barrier comprises rubber barrier cloth, a rubber barrier clamp, a face bow, rubber barrier clamp pincers, a puncher and the like. Punching a hole at the position corresponding to the rubber barrier cloth, sleeving the rubber barrier clamp on the hole, fixing the rubber barrier clamp on the affected tooth, exposing the affected tooth through the hole of the rubber barrier cloth, and finally stretching the rubber barrier cloth by a face bow to separate the affected tooth. In the prior art, the rubber barrier clip is generally clamped on an affected tooth, and if a plurality of affected teeth exist, the rubber barrier clip is fixed on the farthest tooth. However, the existing rubber dam clamp has some problems, which causes the limitation of the use and popularization of the rubber dam in clinic.

1. Edge leakage

Composite resin materials and adhesive systems are particularly sensitive to technology, and proper handling and adequate isolation is critical to successful repair and material life. Isolation in endodontic procedures is also important to maintain good use and to avoid tissue damage and prevent instrument mistaking. Because of the different anatomical structures of each individual, conventional metal dam clamps generally do not fit completely around the neck of the tooth, and therefore gaps often exist between standard dam clamps and the tooth, resulting in marginal leakage.

2. Rubber dam clamp sliding

The traditional rubber barrier clamp is in four-point contact with teeth, continuous surface contact is not formed, and the risk of sliding or falling off of the rubber barrier clamp exists. Clinical crowns that are short, anatomical variations, teeth that are stumps, teeth that are prepped, high gingival margins, worn clips, blunt clip margins, improper clips, etc. also increase this risk. If the clamp slips off, it may cause momentary significant pain and soft tissue damage to the patient.

3. Soft tissue injury possibly caused by clamp of rubber barrier

The rubber barrier clamp is mainly used for clamping the neck of an affected tooth by two beaks to realize fixation, and the beaks of some rubber barrier clamps are provided with teeth to increase the reinforcing capacity. In the use of the dam, the clip must be pushed as far as the root of the tooth as possible, sometimes up to the gingival margin or even below, during which the hard metal of the two beaks of the dam clip may contact the patient's gums, the surface of the tooth root and directly contact and press the oral mucosa, causing pain and discomfort, bleeding of the gums, adhesion damage to the gums or causing an incision in the cementum at the surface of the tooth root. The use of toothed clips, frayed clip edges, blunt edges, or improper clips often cause trauma to the gingival tissue. In addition, prolonged ischemia can lead to loss and retraction of the gingival tissue.

4. The operation difficulty is high

At present, although the rubber dam has a plurality of methods, the rubber dam cloth is required to be sleeved below the wings of the rubber dam clamp, and the rubber dam cloth is tightly attached to the neck of the tooth so as to better seal and isolate the affected tooth. The process has certain operation difficulty, which also influences the popularization of the dam in the oral treatment.

5. Effect in micro-root canal treatment

With the innovation of clinical technology, micro-treatment has become an important part and development direction of root canal treatment. In microscopic root canal treatment, the operation microscope can not only enlarge the root canal system, can also provide sufficient light source entering root canal, makes the art person treat under the direct-view, has greatly promoted the success rate of treatment. However, most of the existing rubber barrier clamps are made of metal materials, and light diffuse reflection appears on the surface of the barrier clamp under the irradiation of a light source of a microscope to cause the phenomenon that light is reflected to enter eyeballs, so that the observation of an operator on an operation area and the discomfort of eyes are affected, the operation difficulty is increased, and the eyesight of the operator is damaged.

The problem is more prominent for some affected teeth with tooth defects. Most of the tooth crowns of the teeth are damaged due to caries and the like, and are called residual crowns, while the tooth crowns are basically lost, and only the tooth roots are remained, and are called residual roots. For the affected teeth needing full crown or inlay repair, after the preparation of the teeth, the occlusal surface and the axial surface of the teeth are partially ground to form a conical state, so as to reserve the space of the prosthesis and the convenient shape for wearing. For these affected teeth with short clinical crowns, serious tooth defects, lack of contact with adjacent teeth, and great difference between the external shape of the tooth and the normal teeth, the conventional rubber barrier clip faces more challenges. The shapes of the residual crown, the residual root and the prepared tooth body are changed greatly, and the conventional rubber barrier clamp is fixed by adopting a point contact with the surface of the tooth and an inverted concave part which is positioned at the most protruded root of the dental crown, so that the conventional rubber barrier clamp cannot be well attached to the neck of the residual crown and the conical tooth of the affected tooth and is easy to slip; and the conventional rubber barrier clamp only clamps the affected tooth or the tooth far away from the affected tooth, so that stable clamping cannot be realized, and leakage is easy to occur. For the residual crown or the tooth after preparing the crown, the rubber barrier clamp with teeth at the rostral part or the rubber barrier clamp with different length of the contact area at the rostral part is generally selected clinically at present, but the conditions of edge leakage and sliding of the rubber barrier clamp are still more common, and the rubber barrier clamp with teeth at the rostral part is also easy to cause tissue damage of the patient, so that the rubber barrier clamp which can realize stable sealing and isolation of the affected tooth and protection of the tissue of the patient is needed clinically.
