Technical Field

The invention belongs to the technical field of dental instruments, relates to a dental filling tool for stomatology, and in particular relates to a water-gate-type filling device suitable for filling dental caries in the neck of a tooth.

Background

In oral clinical diagnosis and treatment, the filling of caries treatment is not separated from a proper filling instrument, and after the humus is removed, the cavity filling is carried out by selecting resin materials, and the sealing between the materials and the filling of dental tissues is the key for preventing secondary caries. Dental caries is common caries of old people, dental caries is narrowed due to morphological characteristics of teeth, the distal end of a traditional water-gate-type dental caries filler is a vertical plane, and for dental caries, especially neck dental caries, the dental caries is difficult to operate, the operation time is long, filling materials at the narrowed part are not easy to fill, the filling is not tight, and the occurrence probability of secondary caries is increased.

The application changes the existing structure, is beneficial to the filling and sealing of the filling body of the tooth neck cavity so as to reduce the occurrence of secondary caries.

Disclosure of utility model

The technical scheme adopted for solving the technical problems is as follows: the water gate filler comprises a handle (2), an upper filling head (1) and a lower filling head (3), wherein one end of the handle (2) is the upper filling head (1), the other end of the handle is the lower filling head (3), the upper filling head (1) comprises a crown-side contact part (4) at the upper end and a gingival-side contact part (5) at the lower end, the gingival-side contact part (5) is fixedly connected with the handle (2) through the crown-side contact part (4), the crown-side contact part (4) is fixedly connected with the handle (2) in a bending way, and the crown-side contact part (4) and the gingival-side contact part (5) are of an integrated forming structure, and the upper filling head (1), namely the gingival-side contact part (5) and the crown-side contact part (4), is of an arc-shaped bent plate structure, and the arc-shaped bending degree of the upper filling head (1) accords with the curve of a connection part of a dental crown and a dental root; the section of the upper filling head (1), namely the gingival contact part (5), which corresponds to the crown side contact part (4) and is parallel to the length direction of the handle (2), is a section B, the included angle theta 1 between the upper end central line of the section B and the central line of the corresponding handle (2) is 90-120 degrees, the included angle theta 2 between the lower end central line of the section B and the central line extension line of the corresponding handle (2) is 30-60 degrees, and is preferably 105 degrees, and theta 2 is 45 degrees; the handle (2) adopts an anti-skid design, and the anti-skid is preferably provided with strip unidirectional lines, longitudinal and transverse bidirectional lines, raised array points and the like on the surface.

The upper end and the lower end of the upper filling head (1) are in arc-shaped bending connection, and the lower end is bent to the handle (2); the upper filling head (1) is basically parallel to one side, namely the inner side, of the tooth and the other side, namely the outer side, of the opposite tooth, but is connected at the most end part by adopting an arc surface;

Meanwhile, the surface of the arc-shaped bent plate structure is also of a trapezoid structure, the surface of the plate corresponding to the arc-shaped bent plate is gradually reduced from the upper end to the lower end of the upper filling head (1), namely, the upper end is wider than the lower end (the width refers to the axial length direction perpendicular to the handle (2)), and the width direction corresponding to the lower end is an arc line.

The beneficial effects of the utility model are as follows: the upper filling head is designed to be trapezoid, the upper end is widened, the bottom of the lower end (gingival end) is retracted, the lower end is in an arc obtuse angle with the upper end, meanwhile, the lower end is narrowed and is matched with the anatomical form of teeth, a doctor can press and mold the filling material quickly and accurately, the sealing between the filling material and tooth body tissues is increased, and the filling head is suitable for clinical filling treatment of dental caries.
