Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an oral shaping piece. Background Art

[0002] Dental caries is one of the common oral diseases. When the interproximal surfaces of the posterior teeth are decayed, it can cause food to get stuck, gingival swelling and pain, and pulpitis. Therefore, timely and effective filling of the interproximal surfaces of the posterior teeth is necessary to restore the interproximal surface appearance of the teeth and extend the service life of the teeth.

[0003] There are two existing technologies. The first is that after the forming sheet crosses the tooth gap, the forming sheet is clamped on the tooth by a forming clamp; the second is a separate forming sheet that does not require a forming clamp and directly crosses the tooth gap. The forming sheet is fixed on the wedge in the tooth gap.

[0004] When filling interproximal caries cavities in orthodontic patients, the first type of forming sheet and forming clip are used together, and the orthodontic wire must be removed, which brings more inconvenience to the patient and the orthodontist; the second type of forming sheet used alone can only be inserted from the side of the tooth without the bracket. If the wedge in the tooth gap is not stuck tightly, the forming sheet may fall into the mouth and even cause the risk of accidental swallowing or aspiration. Therefore, in clinical practice, interproximal caries lesions in orthodontic patients basically require the removal of the orthodontic wire, which causes considerable trouble to the operator.

[0005] Therefore, a kind of oral cavity forming sheet is provided to address the deficiencies in the prior art. Utility Model Content
