Description
Technical field
The present invention relates to biomedical engineering technology field, what be specifically related to is a kind of personalized base station assembly and preparation method thereof.
Background technology
Tooth-planting technology from the sixties in last century be applied to clinical since, owing to thering is ideal support effect, become the mainstream technology of Oral Repair, be deeply subject to the favor of extensive patients.But for repairing, poor, the dummy of patient, especially planting area local condition highly difficult, high request is attractive in appearance requires high labial teeth region, and the finished product base station of system support can not meet clinical needs.
At present, the basic structure of most of Dental Implant system is mainly divided into three parts: implantation body, base station and top artificial tooth.Implantation body is the in-house structure of implantable bone, plays the effect of natural tooth root, to bear functions such as supporting maintenance.Base station is to be positioned at implantation body top, pass gingiva and be exposed to the part in oral cavity, the aspects such as it is the key structure connecting between top artificial tooth and bottom implantation body, stability, stationarity and the aesthetic property of the connected mode of the form of base station and plantation one base station to implant denture play a very important role.
But because whole body condition and the local sclerotin factor of individual patients are not quite similar, the form of required base station is also not quite similar.At present, the businessman that produces in the world base station product is nearly all mass production, base station angle (angle of tooth midline and base station center line composition) is mostly fixing, common are 0 °, 15 ° or 25 °, therefore cannot select at present a base station product that is suitable for every patient completely.The mass production of product must supply selection of clinical by a large amount of product of deposit for each hospital that carries out implant prostheses, and stock's multiplication, has increased cost virtually.In addition, due in plantation secondary operation process, suitable base station need to be installed so that implantation body is connected with top artificial tooth, and the neck portion design of plantation base station directly has influence on the gum edge form of implant-supported formula Full Crown and the health of surrounding soft tissue; Standard base station form is single, can not fundamentally meet the personalized demand of repairing of patient.If can design the personalized base station with aesthstic anatomic form similar to patient's natural teeth, can impel gingival forming, to wear the large step of gum and gingiva moulding two unites two into one, thereby shorten the expense for the treatment of time and temporary crown, and can improve well the gum edge form after plantation is repaired.Therefore, research and development be applicable to the personalized base station system of individual demand become essential.
On the other hand, oral implant rehabilitation, through the development of many decades, has obtained more than 90% success rate at a specified future date.But, operative process complexity, primary stability are not good, in repair process, between implantation body and base station, be difficult in place, chew in process because thereby the stressed base station that makes causes gap generation to cause leakage with respect to the trace movement of implantation body, the problem such as loosening of base station and screw, these all may cause planting the undesirable or repairing failure of repairing effect.The success of implant prostheses depend on to a great extent the form of base station, highly, tapering, material, suitable number, reasonably distribute and the obtaining of common path of insertion.Base station by from the different polytypes that are divided into such as top connected mode, function, material, wherein can be divided into finished product (or preformation) base station and customization base station by production method.With the connected mode of base station on, in conventionally adopting, connect, the method is the trend and direction of implant system development, because it all shows good performance at aspects such as anti-rotation, conduction and dispersive stresses.But, along with the increase of service time, base station is loosening be still clinical in the most common phenomenon.Therefore, current base station is improved, increase the stability of base station in cavity and seem very necessary.
Personalized plantation base station can be divided into following classification according to processing technique at present: the 1. special base station of adjusting and reforming, base station larger preformation is adjust and reform as required by hand to the profile needing, general operation difficulty is larger, spended time is many, the zirconium oxide base station of particularly adjusting and reforming likely causes surperficial micro-crack, causes the damage of base station.2. UCLA base station, the wax cylinder on top or plastic warp add wax sculpture and become the profile of needs together to cast and form together with the metallic substrates of bottom again after adjusting and reforming.The method manufacturing procedure is more, needs to cast with noble metal simultaneously, and processing cost is higher.
Summary of the invention
The object of the invention is to overcome above shortcoming, a kind of personalized base station assembly and preparation method thereof is provided.The base station angle [alpha] of base station body of the present invention and base station form be suffer from according to patient that the angle of tooth and implantation body and form be made suffer from the angle of tooth and implantation body and the personalized base station that form adapts with patient, therefore fully met different patients' individual demand, not only be conducive to improve the aesthetic effect of tooth, also more meet the physiological function of tooth, and, hospital supplies selection of clinical without a large amount of product of deposit, has saved to the full extent medical treatment cost.In addition, owing to increasing internal thread hole in implantation body's linkage section, and increase check washer between set bolt and base station body, greatly improved the stability that base station body is connected with implantation body, improved plantation success rate.
The present invention is achieved in that
Scheme one:
