Abstract
The utility model discloses a nest hole forming device used for filling tooth cavity and forming, which is characterized in that a clipping sheet (1) and a sheet clip (3) on a screw rod (2) form integration. The clipping sheet (1) and the sheet clip (3) clamp teeth in an annular shape through rotating an adjusting nut (4), and the forming filling of the MO hole shape, the DO hole shape, or the MDO hole shape of teeth is once completed. The utility model has the advantages of simple structure and convenient and quick operation, which is an ideal tool for clinical use.
Description
This utility model relates to dentistry, particularly relates to the apparatus that uses when the filling cavity is shaped.
At present, shaping piece and clamp have been widely used for the filling reparation of back dental cavity.During clinical practice,, need to transfer again and select shaping piece to be clamped in folder hole on the shaping piece, just can carry out filling if the cavity size estimation is improper.
If the hole type relates near, the distal surface and the occlusal surface (MDO hole type) of tooth simultaneously, earlier must be with the mesial surface of clamp and shaping piece clamping tooth, make its filling after, the distal surface with clamp and shaping piece clamping tooth carries out filling again.Not only troublesome poeration, effort, time-consuming, and influenced the effect after the filling.
The purpose of this utility model is to provide a kind of nest hole former, and it is a kind of device that replaces shaping piece and clamp, and the clamping tooth is finished the filling reparation once.
This utility model is made up of intermediate plate, sheet folder, screw rod, nut, adjusting nut.Intermediate plate is at an end of screw rod, and sheet folder, nut, adjusting nut be by screw rod, the front end of intermediate plate and sheet folder ringwise, the other end that sheet presss from both sides is integral the other end at screw rod with adjusting nut on nut.
Intermediate plate is the corneous thin slice of Pedicellus et Pericarpium Trapae.
The sheet folder is " U " shape, and the through hole of two correspondences is arranged on the bar of " U " shape, and an end of " U " shape bar has the thin slice identical with the intermediate plate size shape.
One end of screw rod is circular, and there is screw thread the outside of the other end.
The endoporus of adjusting nut has and the identical screw thread of screw rod size, and there is screw thread its outside.
There is the identical screw thread of outside size with adjusting nut the inside of nut.
The utility model has the advantages that: when filling MO type, DO type, MOD type cavity, the clamping tooth is rapid, easy to adjust, can finish the shaping filling to tooth once.The saliva contamination that has caused when having avoided previously because of operating cost has improved filling quality with type again every wet, has reduced dehiscing the time of patient.
With reference to accompanying drawing embodiment, the utility model will be further described:
Fig. 1: nest hole former structural representation.
Fig. 2: nest hole former vertical view.
Fig. 3: sheet folder (3) launches sketch map.
Among Fig. 1-Fig. 2: intermediate plate (1) is fixed on an end of screw rod, through hole (6) on the front end (8) of sheet folder (3), rear end through hole (7), nut (4), adjusting nut (5) are by screw rod (2), intermediate plate (1) presss from both sides (3) front end (8) ringwise with sheet, the rear end of sheet folder (3) is on nut (4), be integral the other end with adjusting nut (5) in screw rod (2).
During use, the front end (8) of intermediate plate (1) and sheet folder (3) is encircled far away, the mesial surface of tooth, during adjusting nut (4), pushing piece folder (3) moves forward or moves backward, the front end (8) that makes intermediate plate (1) and sheet folder (3) is the clamping tooth rightly, the disposable filling reparation of finishing MO hole type, DO hole type or MDO hole type.
Among Fig. 3: front end (8), through hole (6), (7) of sheet folder (3).
Claims (3)
1, a kind of nest hole former that relates to the filling cavity is characterized in that: be made up of intermediate plate (1), sheet folder (3), nut (4), adjusting nut (5), and intermediate plate (1) is at an end of screw rod (2); Sheet folder (3), nut (4), adjusting nut (5) be by screw rod (2), an end (8) of intermediate plate (1) and sheet folder (3) ringwise, the other end of sheet folder (3) goes up at nut (4), be integral the other end in screw rod (2) with adjusting nut (5).
2, nest according to claim 1 hole former, it is characterized in that: intermediate plate (1) is the corneous thin slice of Pedicellus et Pericarpium Trapae.
3, nest according to claim 1 hole former is characterized in that: sheet folder (3) is " U " shape, and through hole (6), (7) of two correspondences are arranged on " U " shape sheet, the thin slice that an end (8) of " U " shape sheet has with intermediate plate (1) is big or small, shape is identical.
