Implantation body's gingival forming base station
Technical field
This utility model relates to a kind of gingiva base station molding device of medical field, particularly a kind of implantation body gingival forming base station.
Background technology
International oral artificial tooth is repaired status of development and shown: the appearance of oral implant rehabilitation technology is the once innovation of traditional Oral Repair science, power is directly imported in the jawbone through implantation body, thereby can bear bigger masticatory force, implant denture base area is less or do not have the base design, makes the patient feel comfortable.Implantation body's synosteosis theory has obtained generally acknowledging of international medical circle of oral cavity at present, and it is the new problem of international and domestic research that implant denture aesthetics repairs, and the focus that the gum end aesthetics of implant denture is studied especially.The deficiency of all gingiva gingival formers of using when implantation body's secondary operation existence is both at home and abroad so far: 1. size does not match, and the base station diameter is thin partially.2. aesthstic not enough: existing gingiva gingival former profile is cylindrical or truncated cone-shaped, but not the irregular form of natural tooth cervical region, and the various kinds of different dental (as the Upper Anterior Teeth cervical region is triangle, the premolars cervical region is a dumb-bell shape) 3. there is not corresponding aesthstic base station: still do not have at present and the similar gingiva gingival former of natural neck portion, make the cervical region aesthetic effect after plantation porcelain hat is repaired not good.The imitative gingiva material of using when adding the plantation delivery closely holds foundation pile or base station position, consequently porcelain hat cervical region can only be the circle of approximate foundation pile, or owing to plant the foundation pile tight parcel of gingiva on every side, force porcelain hat gum edge can only go deep at most under the gum can't accomplishing that gingiva is shaped about 0.5mm.Directly make plantation porcelain hat because of not doing gingival forming, make and receive obviously in the porcelain hat neck edge that form is single, gum edge line is with adjacent teeth on every side or offside gingival margin curve of the same name is extremely asymmetric, coordinate, and very influences the aesthetic effect that the Anterior Implant artificial tooth is repaired.Temporary crown compressing gingival forming technology is arranged at present clinically, but still have following problem: the self-curing resin material of 1. making temporary crown constantly discharges zest self-solidifying monomer to the pessimal stimulation of gingiva generation on every side, make and to utilize gingiva generation chronic inflammatory disease, the hemorrhage or red and swollen phenomenon of gum edge after the temporary crown molding, affect and make the gum edge that permanent porcelain is preced with needed smooth coordination; 2. production process complexity, expense increases; 3. increase patient's number of times of going to a doctor, prolong the plantation repairing efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of can increase plantation porcelain hat gum end aesthetics, simplifies the operation, and shortens the patient and plants repairing efficiency, reduces go to a doctor implantation body's gingival forming base station of number of times and plantation rehabilitation expense of patient.
For achieving the above object, the technical solution adopted in the utility model is: comprise by last transition part, middle forming part, the gingival forming base station made of the pure titanium formed of transition part and interpolation portion or machinable glass ceramic material down, be characterized in, the irregular form of the outline simulating nature neck portion of middle forming part, and offer screw at gingival forming base station central part.
Another characteristics of the present utility model are: the bottom surface of following transition part is to change between 3.5~5.0mm to the height between the last transition part.
Description of drawings
Below in conjunction with accompanying drawing this utility model is described in further detail.
Accompanying drawing is an overall structure sketch map of the present utility model.
The specific embodiment:
Referring to accompanying drawing, this utility model comprises the gingival forming base station of being made up of last transition part 1, middle forming part 2, following transition part 3 and interpolation portion 4, the irregular form of the complete simulating nature tooth of the outline cervical region of middle forming part 2, and be provided with a central screw 5 in gingival forming base station inside, the bottom surface of following transition part 3 is 3.5~5.0mm to the height between the last transition part 1.
This utility model is when the secondary operation of extension secondary method oral implant rehabilitation, it is suitable for reading by the center screw in the central screw 4 on the gingival forming base station this utility model to be installed on implantation body, use this base station to gingival forming 6-8 week, 6-8 gives the patient and removes the gingival forming base station after week, carrying out the porcelain hat on implantation body top on the gingival forming good basis again repairs, consequently porcelain is preced with the more approaching natural dental phenomenon of neck edge form, hat edge gingiva curve and adjacent teeth are coordinated nature, increase denture aesthetics, easy to operate, shorten the plantation repairing efficiency.Specific design can be carried out 3 D stereo scanning to adult's denture standard plaster model (more natural tooth is big) neck portion according to the CAD/CAM principle, scanning result input computer, scaled by adult's tooth form mean values, utilize related software to construct the three-dimensional stereo model of nature neck portion form, press this form design finished product gingival forming base station, computer aided manufacturing gingival forming base station again.The finished product base station of each tooth position divides large, medium and small three kinds of diameters, and high and low two kinds of forms are to adapt to different patients' requirement.
