Abstract

The utility model discloses a kind of die cream switchback suit, it is made up of 2 instruments of leading knife and switchback knife, the switchback of first die during for oral restoration.Leading knife is seal shape, and seal bottom is 2mm blades high raised in plane, and blade is pressed into first die tissue surface during switchback, forms the deep depth of 2mm and indicates ditch.Switchback knife projected depth cue mark at cutter head 2mm, during switchback, the uniform depth according to indicated by depth indicates ditch strikes off die cream, and the depth indicating marker of cutter head can further aid in determining switchback depth.Need to receive the patient of large area removable denture repairing and treating for multiple anodontias, the first die after switchback can reach preferable uniform gap with patient tissue face gap, therefore can obtain more accurate final impression, then produce more particularly suitable artificial tooth.

Description

Die cream switchback is set with

Art

Impression taking used tool when the utility model is related to oral restoration, especially repairs die during large area movable prosthodontics The first die used tool of cream.

Background technology

It is repair mode main at present using removable denture reparation for the patient of multiple absence of tooth in oral cavity.Repair When multiple, the upper lower jaw former of accurate acquirement is first had to, then record plaster cast, the making of removable denture is completed on plaster cast. Take upper and lower dentition former and need to use the pallet being adapted with patient's Dental arch dimension, due to every patient Dental arch dimension form and Edentulous region situation is different from, and ready-made tray only has several models, therefore pallet is often mismatched with patient's dental arch.In order to solve This problem, the patient for clinically being repaired for large area removable denture at present, in order to accurately record upper mandibular dentition and agomphosis Area's form, generally using secondary impression technique impression taking.Secondary impression technique includes that first impression making and final impression are produced.Just Secondary die after obtaining first die, die tissue surface is struck off with cutter using the die cream material that mobility is low, intensity is high 2mm or so, i.e. die cream switchback, individual tray used is produced as patient's final impression.Final impression produce using mobility it is high, The alginate impression material of low intensity, alginate impression material is placed in first die individual tray, is again introduced into patient mouthful It is interior, patient tissue form is accurately recorded.Existing die cream switchback instrument is universal cutter, if can reach textbook The 2mm switchbacks depth of regulation is completely with doctor's range estimation, and switchback depth is often deep mixed, therefore first die after switchback holds in the palm individually Disk does not often reach preferable uniform gap with patient tissue face gap, and have impact on the precision that final impression is produced, and final influence is repaiied Multiple effect.

Utility model content

In order to overcome, existing universal cutter switchback depth is complete to be estimated with doctor, deep mixed deficiency, the utility model A kind of die cream switchback suit is provided, the suit is made up of 2 instruments, it is possible to achieve uniform accurate switchback, realize textbook Requirement to switchback.

The utility model solves the technical scheme that its technical problem used：Design die cream switchback suit, the suit It is made up of 2 instruments of leading knife and switchback knife, is stainless steel.Leading knife is seal shape, and seal bottom is that plane is convex The 2mm blades high for rising, during switchback, blade is pressed into first die tissue surface by leading handle of a knife hand-held first, and seal bottom is flat Face, blade is completely forced into when being in close contact with die tissue surface, and the depth for forming depth 2mm indicates ditch, in first die group Surface of second order positions a plurality of depth and indicates ditch with leading knife in different parts, is that further switchback is prepared.Switchback knife and universal cutter Difference be projected depth cue mark at cutter head 2mm, during switchback, according to depth indicate ditch indicated by uniform depth strike off Die cream, the depth indicating marker of cutter head can further aid in determining switchback depth.

The beneficial effects of the utility model are, for multiple anodontias, it is necessary to receive large area removable denture repairing and treating Patient, more accurate die can be obtained, more particularly suitable artificial tooth is then produced, so as to improve the treatment of repairing and treating Effect.
