Abstract
The bridge-fixed implanted tooth without crown sleeve includes one body part and one connected pile and features that the pile has two wings connected to a fixing unit via a connecting cap or to the wing in other pile. The making process of the bridge-fixed planted tooth includes making female oral cavity mold with the position of adjacent teeth; making male oral cavity mold with fixing unit connecting cap, fixing planted unit and pile connecting core; setting implant pile and welding the two wings with connecting cap; and making the upper structure of the implanted artificial tooth. The present invention makes adjacent teeth share partial pressure and reduces the pressure of the implant tooth to alveolar bone to prolong the service life of the implanted tooth. Separating the implant into two, one outer and one inside, parts facilitates the clinical operation.
Description
Technical field
This invention relates to a kind of novel manual tooth planting's body and preparation method thereof, is applicable to the reparation of a small amount of disappearance tooth Dental Implant fixed denture.
Background technology
The disappearance that Buccodental is repaired by implantation body is comparatively advanced at present a kind of reparation means, and the base portion of Dental Implant directly links with jawbone, and fixes wherein, do not need after the reparation to extract, do not have obvious foreign body sensation, patient's sensation with from body tooth no significant difference, therefore more and more be subjected to patient's welcome.Yet, find that it easily produces phenomenons such as becoming flexible, come off along with the clinical practice of Dental Implant.The important indicator of judging the tooth implant success or not mainly is the degree of implantation body's bone interface healing and the healing degree at implantation body and gingival epithelium interface.Because present Dental Implant base material is mainly titanium alloy, it combines with the physical property that is combined into of alveolar bone, and the frictional force between dependence alveolar bone and base threads fixes, and the synostosis rate of itself and bone interface can not reach 100%.Simultaneously, As time goes on, power directly acts on the absorption that alveolar bone causes alveolar bone, and particularly the alveolar bone around implantation body's apical area and the cervical region is the main concentrated area of stress, also is main clinically bone resorption district.Therefore the success rate at a specified future date and the Biomechanical factor of implantation body are closely related, and too high stress can cause the implant neck surrounding bone to absorb and then cause becoming flexible, coming off of implantation body.Differences such as the existing position that studies show that implantation body's material, shape, size and implantable bone tissue, number can exert an influence to implantation body-bone interface stress, but still can not solve the stress concentration that causes alveolar bone owing to the conduction of power.
In order to address the above problem, traditional fixed bridge Technology Need is made the hat cover on adjacent teeth, and is more to the adjacent teeth wearing and tearing like this, destroys greatly, increases patient's the misery and the feared state of mind, simultaneously because the existence of metal crown cover, influences attractive in appearancely, is not suitable for the labial teeth reparation.

First technical scheme that the present invention adopts is such, it is fixedly bridge-type manual tooth planting body of a kind of nothing hat cover, tooth implant comprises body and the foundation pile that is attached thereto, it is characterized in that: have both wings on the foundation pile, every wing links to each other by retainer attachment cap and retainer or is connected with the wing on another foundation pile.
Second technical scheme that the present invention adopts is such, and promptly a kind of nothing hat cover is manufacture method such as bridge-type manual tooth planting body fixedly, and method comprises: make the oral cavity former, include in this former with prepare after the position of the bonding retainer of adjacent teeth; Make the formpiston of oral cavity denture again, on formpiston, place the retainer attachment cap, the fixing core body that is connected of implantation body and foundation pile, make its position on model with mouthful in identical, place implant abutment, its both wings link to each other with the retainer attachment cap, and welding is fixed it, finish the making of the foundation pile of implantation body's band retainer attachment cap; The superstructure of making implant denture on foundation pile.When wearing tooth fixedly implantation body be threaded with the tooth implant body with the core body lower end that is connected of foundation pile, the foundation pile that will be connected with the retainer attachment cap then is connected with the upper end of core body, the retainer attachment cap is enclosed within on the retainer that is reserved in the oral cavity and bonding, it is damaged promptly to repair patient's tooth.
This invention is exactly a method of not having hat cover fixed bridge by adopting, design and produce out and be fit to manual tooth planting's body that Dental Implant is repaired, improve the implant abutment structure, overcome the deficiency in the treatment of Dental Implant, implant denture and adjacent teeth are connected, power is scattered in adjacent teeth, reduces the pressure of Dental Implant, improve the success rate of implantation of tooth alveolar bone.Simultaneously, do not combine with tooth implant owing to there is hat cover fixed bridge, having overcome does not have the problem of axially rotating in hat cover fixed bridge near, far away in application yet.
The beneficial effect of this invention is that tooth implant all links to each other closely with alveolar bone and adjacent teeth, can disperse the suffered power of implantation body preferably, has also overcome the unusual rotation of tooth implant etc. simultaneously, has prolonged its service life.Zoopery and clinical practice results suggest, the Dental Implant method of this invention is in the process of repairing absence of tooth, near, late result observation by postoperative January-December, estimate indication and comprise gingival hemorrhage index, loosening degree index, X line tooth sheet indication etc., adopt the multiplicity legal system to make the index accepted of Dental Implant success standard, the Dental Implant success rate of phase section when observing each, found that in the late result, fixedly the success rate of bridge-type tooth implant is apparently higher than matched group (P＜0.05) not have the hat cover, and its concrete testing result is as shown in the table.
