Description

Hand-held appliance for assisting tooth adjacent surface forming

Technical Field

The utility model relates to a medical appliance, in particular to a hand-held appliance for assisting the shaping of the adjacent surface of a tooth.

Background

The incidence of distal and proximal caries lesions in the second molar continues to increase due to the non-orthostatic eruption of wisdom teeth. Filling of distal caries lesions in second molar after extraction of wisdom teeth is a major difficulty for clinical work. At present, the mode of clamping and adding the molding plate to the molding plate is mainly applied clinically to help the far-middle noodle formation. However, the far-middle surface recovered by the forming plate system is too straight and does not conform to the arc appearance contour of the tooth anatomy, and the risk of the affected tooth to suffer from tooth fracture, secondary caries and periodontal disease is increased. Meanwhile, as the far middle carious lesion edge of the second molar is usually positioned under the gum, and the walls of the buccal and lingual axes are mostly damaged and affected, when the existing molding plate system is in place, after the gum direction is ensured to be jointed with the tooth surface, the molding plate of the occlusal direction is naturally and outwards opened and cannot be tightly jointed with the edges of the buccal and lingual holes, so that the edges of the buccal and lingual holes filled with the immediate filling body generate overhang.

In addition, in the case of the existing molar or molar with the adjacent tooth caries and the adjacent tooth still exists, the traditional molding plate system still has limited effect of molding the adjacent tooth, so that the filling body cannot form an ideal adjacent relation with the adjacent tooth. Even when the position of the adjacent tooth is abnormal or caries damages the side wall and the cusp of the cheek and tongue, the conventional molded strip cannot be attached to the adjacent tooth, so that the immediate filling of the filling body loses the adjacent surface contact with the adjacent tooth.

No matter the form of the over-straight adjacent surface, poor adjacent relation or the buccal tongue side hole edge overhang, a large amount of later trimming operation is clinically needed, time and labor are wasted, the mouth opening time of a patient is increased, and the burden is caused on the temporomandibular joint of the patient.
