Description
Technical field
Oral cavity medical apparatus technical field is the utility model is related to, more particularly to a kind of straight base station planting body of titanium zirconium anti-rotation
System.
Background technology
With the continuous development of tooth-planting technology, " implant tooth " technology is gradually ripe and stably.Implant tooth is first
The high titanium artificial tooth root of biocompatibility is inserted into fixed, suture in teeth groove, and treated through the several months in artificial tooth root and teeth groove
Bone stable connection after (concept for embodying Integrated implant), then carry out follow-up artificial tooth installation.The artificial tooth root of " implant tooth "
Directly it is connected with bone, preferable support force can be provided, harder food can be chewed and very popular.Wherein artificial tooth
Plant success rate and totally coordinate attractive in appearance to be most concerned two problems of people naturally.
The planting body that " implant tooth " uses can be divided into single-piece and multi-piece type according to type, can be divided into according to planting patterns
Implantation type and non-implantation type.The less-restrictive of implant depth when the advantages of single-piece planting body is to be implanted into, and planting body is more
It is firm, it is not easy to break, but its shortcoming is that single-piece planting body can protrude from about 1 centimetre of the bone plane, and then waiting bone whole
During conjunction, the single-piece planting body easily because Occlusal interference of the dental implant surgical person in chewing on things, causes Integrated implant
Intensity deficiency, influence to plant the steadiness after tooth, the problem of causing bone atrophy and plant tooth is failed, in addition, single-piece kind
Implant can not also coordinate with other external members again, and the programmable space of corona and type are less.And planted for more than one piece implantation type
For body, advantage is that another aspect coronal can carry out multiple design, can the problem of on the one hand can effectively avoiding Occlusal interference
Different facing part designs are coordinated to be combined fixation.But its shortcoming is that multi-piece type planting body must be accurately sealed and be cut flat with
In bone plane, with the engagement of sharp follow-up coronal.Because the uncertainty operated on medicinal, generally make multi-piece type planting body
Bone plane is excessively locked, interior during Integrated implant, the planting body is possible to be healed by the epidermis bone layer, and is covered by micro-
Lid, cause the difficulty of follow-up coronal engagement.Such as multi-piece type, the planting body lock table entry osteoderm head layer is excessively shallow, then can cause screw thread
Exposed, exposed screw thread is possible to breed bacteria and produces lesion.An other shortcoming be multi-piece type planting body structural strength compared with
Difference, the coronal is fixed on by way of screw threads for fastening on multi-piece type planting body, and coronal is arranged at soft group
In tissue layer, the support force deficiency of coronal horizontal direction is caused, thus when coronal is pressed by the shearing of horizontal direction, easily
There is the problem of screw thread sealed structural break, once the sealed structural break of screw thread, remaining screw thread closure is still locked on the plantation
In vivo, taking-up is not easy, and is repaired extremely difficult.
In recent years, increasing doctor and patient expect that planting body can load at once, and load at once is substantially shorter
The course for the treatment of repaired is planted, patient's function at once and attractive in appearance is brought, how to realize that load at once just turns into research heat in recent years
Point.The primary stability of planting body is the key loaded at once, is focused primarily upon in the research in terms of planting body outside to planting body
Shape, helicitic texture and surface treatment etc., in addition Bone condensing technology can also improve planting body primary stability, but Bone condensing
Technology needs to use special osteotomes, considerably increases operating difficulty and treatment cost.
At present, the helicitic texture of planting body uses single thread structure more, from mechanics and it is mechanistic in terms of from the point of view of, single thread
Cutting resistance is big caused by structure, it is easy to produces bone and burns, stress concentration occur, planting body is produced fine fisssure at fluting
Crack initiation, the infringement to alveolar bone is larger, is easily caused plantation failure；
Preferably plantation dental restortion is not only embodied on the firmness and service life of planting body, it is often more important that
Obtain and the coordination of surrounding tissue and remaining denture, attractive in appearance.
The content of the invention
The purpose of this utility model is, for being operated not on above-mentioned existing multi-piece type implant Ya Yiyin medicinals
Certainty, cause to be combined difficulty with coronal or cause bacteria breed；Screw thread closing component structure easy fracture；Cutting resistance is big, holds very much
It is also easy to produce bone to burn, stress concentration occurs, planting body is produced fine fisssure crack initiation at fluting, the infringement to alveolar bone is larger,
The problem of being easily caused plantation failure and being unable to reach effect that is attractive in appearance and repairing, proposes that one kind uses Double-layer threaded planting body,
The ceramic anti-rotation bent angle installation planting body of multi-piece type, the implant system realizes stability and intensity is high, can be adapted to each
