Description
Technical field
The present invention relates to oral cavity medical apparatus technical field, specifically a kind of planting system based on titanium-zirconium alloy
System.
Background technology
With the continuous development of tooth-planting technology, " implant tooth " technology is gradually ripe and stable.Implant tooth is first
Titanium artificial tooth root high for bio-compatibility is inserted fixed, suture in teeth groove, and is treated in artificial tooth root and teeth groove through the several months
Bone stable connection after, then carry out follow-up artificial tooth installation.The artificial tooth root of " implant tooth " is directly connected with bone, can be provided
Preferably support force, can be chewed to harder food and very popular.Wherein manual tooth planting's success rate and overall from
It is most concerned two problems of people so to coordinate attractive in appearance.
The plant tooth body that " implant tooth " is adopted 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.Single-piece plants the less-restrictive of implant depth when the advantage of tooth body is to be implanted into, and plants tooth body more
Firm, not easy fracture, but its shortcoming is that single-piece is planted tooth cognition and protrudes from about 1 centimetre of the epidermis bone layer, and then is waiting
During Integrated implant, the single-piece plants tooth body easily because Occlusal interference of the dental implant surgical person in chewing on things, causes bone whole
The intensity of conjunction is not enough, affects the steadiness after planting tooth, causes the problem of bone atrophy and makes plant tooth fail, in addition, single-piece
Formula is planted tooth body and also cannot be coordinated with other external members again, and the programmable space of artificial tooth and type are less.And for more than one piece implantation type
For planting tooth body, advantage is that the problem that on the one hand can be prevented effectively from Occlusal interference, another aspect coronal can carry out various setting
Meter, can coordinate different facing part designs to be combined fixation.But its shortcoming be multi-piece type plant tooth body must accurately sealed simultaneously
Cut flat with epidermis bone layer, with the engagement of sharp follow-up coronal.Because the uncertainty operated on medicinal, generally makes many
The part formula plant tooth body excessively lock table entry osteoderm head layer, during Integrated implant in, the plant tooth body is possible to by the epidermis bone layer
Healing, and by micro- covering, cause the difficulty of follow-up coronal engagement.Such as the multi-piece type plant tooth body lock table entry osteoderm head layer mistake
Shallow, then screw thread can be caused to expose, the screw thread for exposing is possible to breed bacteria and produces pathology.An other shortcoming is that multi-piece type is planted
Tooth body structural strength is poor, and the coronal major part is to be fixed on multi-piece type to plant on tooth body by way of thread locking, and is preced with
Shape portion is arranged in soft tissue layer, causes the support force of coronal horizontal direction not enough, thus when coronal is subject to horizontal direction
Shearing when pressing, tend to have the problem of screw-locking structure fracture, once screw-locking structure fracture, remaining spiral lock is still locked on the plant
In tooth body, taking-up is difficult, and repairs extremely difficult.
Stability and later stage corona, base station and planting body company in the mid-early stage planting body (root of the tooth) of implant tooth process
The fastness for connecing is the key of the final success of tooth-implanting.
In recent years, increasing doctor and patient expect that planting body can be loaded at once, and load at once is substantially shorter
The course for the treatment of that plantation is repaired, brings patient's function at once and attractive in appearance, how to realize loading at once the research heat for just becoming in recent years
Point.The primary stability of planting body is the key for loading at once, and the research in terms of planting body focuses primarily upon external to planting
Shape, helicitic texture and surface treatment etc., in addition Bone condensing technology can also improve planting body primary stability, but Bone condensing
Technology needs, using special osteotomes, to considerably increase operating difficulty and treatment cost.
At present, the helicitic texture of planting body more adopt single thread structure, from mechanics and mechanistic in terms of from the point of view of, single thread
Cutting resistance produced by structure is big, it is easy to produces bone and burns, stress concentration occurs, makes planting body produce fine fisssure at fluting
Crack initiation, the infringement to alveolar bone are larger, are easily caused plantation failure.
Preferably plantation dental restortion has not only been 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.Wherein base station extremely closes weight with " passive suitable " of planting body, corona
Will, natural root of the tooth is all asymmetrical and not completely vertical direction in most cases, and planting body need according to
The direction of original root of the tooth is implanted into, and corona can be caused not straight using straight base station in this case, it is impossible to reach effect that is attractive in appearance and repairing
