Description

Manual tooth planting's system
Technical field
This utility model relates to oral cavity medical apparatus technical field, relates in particular to a kind of manual tooth planting's system.
Background technology
Along with the development of tooth-planting technology, " implant tooth " technology is gradually ripe and stable.Implant tooth be first titanium artificial tooth root high biocompatibility is inserted in teeth groove fixing, sew up, and through the several months after the bone stable connection in artificial tooth root and teeth groove, then carry out follow-up artificial tooth installation.The artificial tooth root of " implant tooth " is directly combined with bone, and preferably support force can be provided, can be very popular to chewing compared with hard food.The fastness being connected with implantation body at the stability of the mid-early stage implantation body (root of the tooth) of implant tooth process and later stage corona, base station is the key of the final success of Dental Implant.
In recent years, increasing doctor and patient expect implantation body's load at once, and load at once can be shortened the course for the treatment of that plantation is repaired greatly, bring function at once of patient and attractive in appearance, and how realizing load at once just becomes study hotspot in recent years.The primary stability of implantation body is the key of load at once, research aspect implantation body mainly concentrates on implantation body's profile, helicitic texture and surface treatment etc., in addition bone extrusion technique also can improve implantation body's primary stability, but bone extrusion technique need to adopt special osteotomes, operating difficulty and treatment cost are greatly increased.Studies have found that to implantation body and add self tapping groove, Neng Shi implantation body possesses self tapping performance, without tapping step, can directly implantation body be screwed in the hole of getting ready, can produce to a certain extent bone extrusion effect.At present the structure of self tapping groove mainly with vertical, skewed slot is common, and two end faces of fluting are plane, and the angle of two planes be 90 ° in the majority.From mechanics and mechanistic aspect, vertically self tapping groove stressed substantially concentrating on a line in the time of cutting connecting hole, the cutting resistance producing is large, is easy to produce bone and burns; And vertically self tapping groove belongs to front clearance structure, the bone bits that produce in self tapping process cannot discharge or hold, and make the corner of vertical self tapping groove occur stress concentration, make implantation body produce micro-crack cracking at fluting place, cause planting unsuccessfully.Although skewed slot and implant axis are to having formed certain cutting angle, cause skewed slot more easily to cut than vertical self tapping groove, but being limited to the elongated cylindrical structural feature of implantation body, the angle of skewed slot fluting and the length of fluting restrict the included angle that cannot reach desirable and desirable fluting volume each other.
In addition on the one hand, existing base station and implantation body adopt four jiaos, hexagonal and anistree equal angles type to be connected, and this connected mode is prone to base station and implantation body produces micro-rotation, and osseous tissue healing rate is slow, the very difficult assurance of primary stability; And make implantation body part occur stress concentration, cause frontal resorption.Even if adopt central bolt in addition fastening, because implantation body is undersized with base station, cannot in production, accomplish fitting together perfectly truly, trickle rotation cannot be avoided.In the time there is trickle rotation, the face of angle type connection script and the Stress Transfer of face have just become the Stress Transfer of line and face, when stress is excessive or when long stress accumulation, just easily cause damage and the degeneration of junction, the rotation of implantation body and base station, loosening, thereby make manual tooth planting's failure, all that has been achieved is spoiled.
