Abstract
The utility model discloses a gingiva protector for tooth preparation. The gingiva protector for tooth preparation comprises a main rod, an S-shaped auxiliary retractor, a subsidiary rod and a gingiva arrangement device, wherein the S-shaped auxiliary retractor is arranged in front of the main rod, the subsidiary rod is arranged at the front end of the main rod, and the gingiva arrangement device is arranged at the front end of the subsidiary rod and is apparently in a segment shape. During tooth preparation clinically, if gingivae are not pushed and pressed by the gingiva arrangement device when subgingival shoulder parts are prepared, sulcular epitheliums of the gingivae can be possibly damaged by a bur. If users can use the gingiva protector for tooth preparation during tooth preparation, the free gingivae can always keep to be pushed away, so that gingival tissues are well protected. The gingiva protector for tooth preparation integrates functions of arranging the gingivae and pulling mouth corners with a mouth mirror, and accordingly operation of clinicians is facilitated, damage to the gingivae during tooth preparation is greatly reduced, and the gingiva protector for tooth preparation can be popularized and applied.
Description
Technical field
This utility model relates to a kind of tooth that is equipped with and uses the gingiva protector, belongs to the Oral Repair field.
Background technology
At present; Oral repairing clinic is to labial teeth, when premolars complete crown dummy carries out tooth preparation; Lip, cheek side are for guaranteeing requirement attractive in appearance, and normal the selection prepares shoulder under the gum, and still do not have the method that effectively intercepts car pin and gingiva; Usually damage patient's gingiva tissue inevitably, bring unnecessary damage and misery to the patient.
Summary of the invention
To above-mentioned prior art, this utility model is to alleviate the damage of tooth preparation process to patient's gingiva, and the spy works out can push free gum open when tooth preparation, take into account the stretching bicker simultaneously uses the gingiva protector with a kind of novel tooth that is equipped with that keeps getting a clear view.
This utility model is realized through following technical scheme:
A kind of tooth that is equipped with is used the gingiva protector, comprises mobile jib, S shape auxiliary drag hook, secondary bar and row's gum device, and wherein, the auxiliary drag hook of S shape is located at the mobile jib front portion, and secondary bar is located at the mobile jib front end, and row's gum device is located at secondary bar front end, and row's gum device profile is segment shape (arc surface).
Said secondary bar and mobile jib angulation during practical application, can be selected different angles according to demand between 0 °～90 °, to adapt to different tooth position (like labial teeth, premolars) when operation tractive lip, BT more easily.
Clinical when carrying out tooth preparation, when preparing to gum the shoulder part, if arrange gum device pushing gingiva, then the car pin might injure epithelium in the ditch of gingiva.And if in the tooth preparation process, the operator can use the tooth that is equipped with of this utility model to use row's gum device, then can remain and push free gum open, play the effect of good protection gingiva tissue.
Being equipped with tooth and can stretching in patient's labial gingiva ditch with the gingiva protector of this utility model,, the gum that will dissociate simultaneously pushes to lip buccal side and root side, has avoided effectively that the car pin stretches into the damage to epithelium in the ditch that gingival sulcus possibly cause in the tooth preparation process.The design of auxiliary drag hook makes the operator when using this utility model, can in row's gum, protection gingiva tissue, fully draw back lip, bicker soft tissue, keeps the clear of the visual field.Row's gum device is circular arc, just in time meets lip side neck portion's tooth body and gingival contour, can whole labiad side of gingiva and root side be passed, and has fully intercepted contacting of car pin and gingiva, has protected gingiva tissue well.
The function that this utility model will be arranged gum and mouth mirror pulling mouth corner rolls into one, and makes things convenient for clinicist's operation, has alleviated greatly in the tooth preparation process the damage of gingiva, can apply.

The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described.
A kind of tooth that is equipped with is used the gingiva protector, comprises mobile jib 1, the auxiliary drag hook 2 of S shape, secondary bar 3 and row's gum device 4, and is as shown in Figure 1; Wherein, the auxiliary drag hook 2 of S shape is located at mobile jib 1 front portion, and secondary bar 3 is located at mobile jib 1 front end; Row's gum device 4 is located at secondary bar 3 front ends, and row's gum device 4 profiles are segment shape (arc surface).
Said secondary bar 3 and mobile jib 1 angulation during practical application, can be selected different angles according to demand between 0 °～90 °, to adapt to different tooth position (like labial teeth, premolars) when operation tractive lip, BT more easily.
Use: during tooth preparation, will arrange gum device 4 and stretch in the gingival sulcus, gum labiad side and the root side pushing that will dissociate, obstruct car pin contacts with the interior epithelium of free gingival groove, plays the effect of protection gingiva.Simultaneously, the auxiliary drag hook 2 of S shape can guarantee pulling mouth corner effectively, keeps the clear of the operator visual field.
Clinical when carrying out tooth preparation, when preparing to gum the shoulder part, if arrange gum device pushing gingiva, then the car pin might injure epithelium in the ditch of gingiva.And if in the tooth preparation process, the operator can use the tooth that is equipped with of this utility model to use row's gum device, then can remain and push free gum open, play the effect of good protection gingiva tissue, as shown in Figure 2.
Being equipped with tooth and can stretching in patient's labial gingiva ditch with the gingiva protector of this utility model,, the gum that will dissociate simultaneously pushes to lip buccal side and root side, has avoided effectively that the car pin stretches into the damage to epithelium in the ditch that gingival sulcus possibly cause in the tooth preparation process.The design of auxiliary drag hook makes the operator when using this utility model, can in row's gum, protection gingiva tissue, fully draw back lip, bicker soft tissue, keeps the clear, as shown in Figure 4 of the visual field.Row's gum device is circular arc, just in time meets lip side neck portion's tooth body and gingival contour, can whole labiad side of gingiva and root side be passed, and has fully intercepted contacting of car pin and gingiva, has protected gingiva tissue well, and is as shown in Figure 3.
