Description

Artificial tooth's multi-piece type implant system
Technical field
This utility model relates to oral cavity medical apparatus technical field, relates in particular to a kind of artificial tooth's multi-piece type implant system.
Background technology
Along with the development of tooth-planting technology, " implant tooth " technology is gradually ripe and stable.Implant tooth is first the high titanium artificial tooth root of biocompatibility to be inserted to fixing in teeth groove, stitching, and after the bone stable connection in artificial tooth root and teeth groove, (embodies the concept that bone is integrated) through the several months, then carries out follow-up artificial tooth installation.The artificial tooth root of " implant tooth " is directly connected with bone, and preferably support force can be provided, can be very popular to chewing compared with hard food.Wherein manual tooth planting's success rate and overall two problems that the coordination people of being attractive in appearance are concerned about most naturally.
The implantation body that " implant tooth " adopts can be divided into single-piece and multi-piece type according to type, according to planting patterns, can be divided into implantation type and non-implantation type.When being to implant, the advantage of single-piece implantation body plants the less-restrictive of the body degree of depth, and implantation body is comparatively firm, easy fracture not, but its shortcoming is single-piece implantation body and can protrudes from approximately 1 centimetre, this bone plane, and then in waiting between bone integration period, this single-piece implantation body is easily because the Occlusal interference of dental implant surgical person when chewing on things, the undercapacity that causes bone to integrate, the steadiness after tooth is planted in impact, cause the problem of bone atrophy and make to plant tooth failure, in addition, single-piece implantation body also cannot coordinate with other external members again, the programmable space of corona and type are less.And for Duo Jian implantation type implantation body, advantage is can effectively avoid on the one hand the problem of Occlusal interference, coronal can carry out various design on the other hand, can coordinate different facing part designs to combine fixing.But it is must be accurately sealed and cut and put down in bone plane that its shortcoming is multi-piece type implantation body, in order to the joint of follow-up coronal.Because medical treatment is the uncertainty of operation clinically, conventionally make multi-piece type implantation body too lock bone plane, between bone integration period in, this implantation body is likely subject to the healing of this epidermis bone layer, and by micro-covering, the difficulty that causes follow-up this coronal to engage.As excessively shallow in this implantation body's lock table entry osteoderm head layer of multi-piece type, can cause screw thread to expose, the screw thread exposing is breed bacteria and produce pathological changes likely.An other shortcoming is that multi-piece type implantation body structural strength is poor, this coronal major part is that the mode by screw threads for fastening is fixed in multi-piece type implantation body, and coronal is arranged in soft tissue layer, cause the support force of coronal horizontal direction not enough, thereby the shearing that is subject to horizontal direction when coronal is when exert pressure, and easily has the problem of the sealed structural break of screw thread, once the sealed structural break of screw thread, remaining screw fastening component is still locked in this implantation body, takes out and is difficult for, and repairs quite difficulty.
At present, desirable Dental Implant reparation is not only embodied in the firm degree and service life of implantation body, and the more important thing is will acquisition and the coordination of surrounding tissue and remaining denture, attractive in appearance.Wherein " passive being applicable to " of base station and implantation body, corona is most important, natural root of the tooth is all asymmetrical and is not vertical direction completely in most cases, and implantation body need to implant according to the direction of original root of the tooth, use in this case straight base station can cause corona not straight, cannot reach effect attractive in appearance and that repair.
