Description
Technical field
This utility model relates to a Dental Implant positioning auxiliary device.
Background technology
Artificial implant treatment is the titanium root of the tooth to be implanted in the jawbone of sufferer oral cavity agomphosis part, to substitute the nature root of the tooth by the doctor.Manually planting tooth ruling by law and treat agomphosis except having firm planting body supports, in masticatory function or stability and in appearance, is good than traditional artificial tooth patchery all, and therefore artificial tooth implantation technology has become artificial in recent years artificial tooth and planted the body treatment and go up development trend.At present artificial dental implant surgical success rate about 65～90%, the location is improper when pointing out that according to clinical report the main cause of dental implant surgical failure is that root of the tooth is implanted, cause plant behind the tooth maxillary nerve or sinus highmori impaired, cause sequela such as lifelong lower jaw paralysis or masticatory function forfeiture.At present general artificial operational approach of planting tooth, as shown in Figure 6, dentist must bore on patient's gingiva 61 point 63 that gos deep into to dental bed bone 62 thoroughly, planting body 64 with one more afterwards is fixed in the point 63 of dental bed bone 62, so, treat that then can utilize this to plant body 64 after a period of time installs an artificial tooth 65 thereon.Wherein, this dental implant method must get out a little 63 in the wideest or the strongst place at dental bed bone 62, and can not get into neural 66 when boring.Yet, at present dentist in boring entirely with the personal experience, so on clinical operation, often can't be drilled in the wideest or the strongst place with putting 63 very accurately, and bore position and angle etc. also possibly can't be vertical with occlusal surface, and then generation bore position deviation, and drilling depth crosses dark and injures nerve, plants the tooth failure so that cause.
Other has the manufacture method of a conventional tooth mould location-plate, it must pass through correction of the flank shape earlier, then on model, the tooth of agomphosis is reverted to original appearance with wax (Wax), the reuse Gypsum Fibrosum duplicates one, make a template (Template) with the acryl thin slice of thickness about 1.5～2 millimeters (mm) on vacuum forming machine then, last reuse resin (Self-Curing Resin) is poured on the template, is placed on edentulous region, copying the tooth of edentulous region, and then form the tooth mould location-plate of transparency.Yet the production process of this structure must so not only cause the diagnosis and treatment program tediously long consuming time based on manually mostly, and the tooth mould location-plate of its made also can't guarantee fully also that quality and profile can reach re-set target.
Because through the obtained structure of above-mentioned each method, not only formality complexity, and also can't provide an accurate ground auger hole in patient's dental bed bone, therefore all have the nerve of injuring, so that plant the risk of tooth failure.
The utility model content
This utility model main purpose is, overcome the problems referred to above that known skill meets with and provide a kind of can be at patient's custom-made by size, what foundation had four point location functions plants the tooth auxiliary device, and it accurately gets out a hole in DIYU patient's the dental bed bone and can be made for to avoid injuring nerve and minimizing and plant the tooth failure and plant the auxiliary usefulness of tooth.
This utility model secondary objective is, can increase the precision of planting tooth and safety to reduce operation risk.
Another purpose of this utility model is, significantly shortens time that artificial tooth root implants amount of bleeding when planting tooth to reduce the patient.
This utility model purpose again is, the effect of can reach medical digitized, changing and oversimplify rapidly.
To achieve these objectives, the technical scheme that this utility model adopted is: a Dental Implant positioning auxiliary device, and it sees through the oral cavity scan-image data that 3D numeral tomoscan produces a patient before planting tooth, and it comprises:
One stocking mechanism in order to the data relevant with a plurality of anchor points of any previous foundation to be provided, and stores any newly-built locating point data relatively;
One computer mechanism, in order to import this patient's oral cavity scan-image data, capture according to agomphosis position wherein and to correspond to certain dental bed specific location data relevant in this stocking mechanism with anchor point, produce one first reference point data and one second reference point data according to this, produce on one locating point data and locating point data once according to this by these first and second reference point data again, and this is planted 3D mathematical model geometric data after the tooth emulation provide and show output; And
One location auxiliary body, its output according to this computer mechanism forms, and it has the bottom on top and a relative top, this bottom is chimeric to be arranged on the denture of this patient's agomphosis portion relatively, tooth mould with this denture, and in this top and its underpart all have on one first reference point, one second reference point, an anchor point and anchor point once, wherein should go up anchor point and be positioned at the last radius junction of this top in this first and second reference point, this time anchor point is positioned at the following radius junction of this bottom in this first and second reference point.
The given data that these first and second reference point data are served as reasons and captured in this stocking mechanism.
These first and second reference point data comprise radius data on respectively, in order to produce locating point data on this according to this via this computer mechanism.
These first and second reference point data comprise radius data respectively, in order to produce this time locating point data according to this via this computer mechanism.
This mathematical model geometric data comprises plants angle, length, accurate location and the degree of depth that body is implanted.
And produce newly-built upper and lower locating point data through this computer mechanism at every turn and all be stored in this stocking mechanism, and be established as archives.
The last radius of this first and second reference point is greater than following radius.
Compared with prior art, the beneficial effect that this utility model had is: this utility model can be when planting the dental drill hole, plant body and implant required angle, length, accurate location and the degree of depth by obtaining according to tooth 3D mathematical model geometric data on the positioning auxiliary mechanism, utilize the positioning action of its upper and lower anchor point, accurately get out a hole in the DIYU patient dental bed bone, plant the tooth failure and can avoid injuring nerve and minimizing, plant the auxiliary usefulness of tooth to be made for.By this, not only can increase the precision of planting tooth and safety, also can significantly shorten the time that artificial tooth root is implanted simultaneously, the amount of bleeding when planting tooth, and then the effect that reaches medical digitized, changes and oversimplify rapidly to reduce the patient to reduce operation risk.
