Description

General-purpose type is manually planted dental structure

Technical field

The present invention relates to a kind of dental structure of manually planting, relate in particular to a kind of general-purpose type and manually plant dental structure.

Background technology

Along with the technical development of " manually planting tooth " is gradually ripe and stable, manually planting tooth is to utilize the artificial tooth root of the high titanium of biocompatibility to insert fixing and stitching in the teeth groove earlier, and through after treating after several months that the interior bone of artificial tooth root and teeth groove is connected firmly, carry out the action of subsequent installation artificial tooth again.Because artificial tooth root is directly to be connected with bone, thereby preferable support force can be provided, and can chew and very popular harder food.And manually plant tooth plant that the tooth build can be divided into single-piece or multi-piece type is planted the tooth body, single-piece plants the tooth body such as United States Patent (USP) discloses No. 2010/0119993 " Dental Implant ", the structure that single-piece is planted the tooth body be directly insert behind the bone bed of dental bed and the epidermis bone layer fixing, after treating several months, this single-piece is planted tooth body and bone bed and epidermis bone layer and is carried out bone when integrating fixedly, carries out molding again and then directly sheathed this single-piece that is fixed in of facing spare is planted on the tooth body.When being to implant, the advantage of aforesaid way plants the less-restrictive of the body degree of depth, and it is comparatively firm to plant the tooth body, easy fracture not, but its shortcoming is single-piece and plants tooth cognition and protrude from about 10 millimeters of this epidermis bone layer, and then in waiting between the bone integration period, this single-piece is planted the tooth body easily because the interlock of dental implant surgical person when chewing on things disturbed, the undercapacity that causes bone to integrate, influence is planted the steadiness behind the tooth and then may be caused the problem of bone atrophy and make and plant the tooth failure, in addition, single-piece is planted the tooth body and also can't be cooperated with other external members again, and the programmable space of artificial tooth and type are less.

Multi-piece type is planted the tooth body and is then disclosed No. 2007/0254265 " Dental Implant " as United States Patent (USP), multi-piece type is planted the tooth body and then will be planted the tooth body and be divided into and plant tooth body (implant), Zhi Taiti (abutment) and coronal (crown), to plant the tooth body when planting tooth earlier is implanted in the bone bed and epidermis bone layer (cortical bone) of this dental bed, and make this plant the tooth body not protrude from this epidermis bone layer, be coated with one deck soft tissue (soft tissue) layer on the epidermis bone layer, just be the oral cavity on this soft tissue layer, so this is planted the tooth body and can not be subjected to interlock disturb after implanting.And wait to plant tooth body and this bone bed and epidermis bone layer carry out bone integrate fixing after, go this soft tissue layer of surgical incision and be fixed in this and plant on the tooth body this Zhi Taiti is sealed again, carry out molding at last and make coronal and will be fixed in and protrude on the outer Zhi Taiti of this soft tissue layer.The advantage of this mode is effectively to avoid the problem of interlock interference, and this coronal is to carry out various design on the other hand, and can cooperate different facing spares designs to make up fixing.But it is must be accurately sealed and cut and put down on epidermis bone layer, in order to the joint of follow-up coronal that its shortcoming is that this plants the tooth body.For instance, because the uncertainty that medical treatment is operated clinically makes this plant the tooth body and too locks this epidermis bone layer, in then between the bone integration period, this plants the healing that the tooth body might be subjected to this epidermis bone layer, and is covered slightly, causes the difficulty of follow-up this coronal of joint.An other shortcoming is that structural strength is relatively poor, because this coronal major part is the mode by screw lock to be fixed in this and to plant on the tooth body, and this coronal is to be arranged in this soft tissue layer, the support force that causes this coronal horizontal direction is comparatively not enough, thereby the shearing that is subjected to horizontal direction when coronal easily has the problem of screw lock structural break when exerting pressure, in case screw lock structural break, remaining spiral lock still is locked on this and plants in the tooth body, takes out to be difficult for, and repairs quite difficulty.Therefore, in this case this planted tooth body and this Zhi Taiti and respectively had one and be connected the surface and make this plant the tooth body to be connected with this Zhi Taiti and to form an abutment (abutment joint), this coronal then is connected in this abutment, increases horizontal shear by this, to avoid the problem of transverse breakage.

But the planting dental structure and after planting tooth body installing, can protrude from about 10 millimeters of this epidermis bone layer of single-piece, and planting of two pieces type also can protrude from about 10 millimeters of this epidermis bone layer after dental structure is installed this Zhi Taiti, if the interlock space between the last lower tooth of sufferer than hour, then must be with the worn one section height of the Zhi Taiti that plants tooth body or two pieces type of single-piece with realistic use, quite inconvenience in the use.And dentist must be prepared the dental structure of planting of planting dental structure and two pieces type of single-piece respectively, use with the demand that cooperates different sufferers, and the dental structure of planting of single-piece and two pieces type can not commonly use, and comparatively inconvenience in the use, and cost is also higher.

See also shown in Figure 1A and Figure 1B, because it is actual when planting tooth, this dental bed 1 is not necessarily smooth, but may have according to patient's dental bed 1 growth or the situation of projection, and make that general two pieces type plants dental structure plant tooth body 2 in implanting this dental bed 1 time, shown in Figure 1A, because this is planted tooth body 2 and exposes to outside this dental bed 1, cause the not good problem of impression, in addition, because this surface of planting tooth body 2 is provided with a plurality of screw threads, and the screw thread that exposes might breed bacteria and is produced pathological changes, in order to avoid screw thread to expose, must carry out the processing in the non-genus specification, but not belong to the suitable time and effort consuming of processing mode in the specification.Again might be as shown in Figure 1B, this is planted tooth body 2 and too gos deep into this dental bed 1, the difficulty when causing the installing of the follow-up Zhi Taiti of carrying out.Improved necessity is arranged in fact.

Summary of the invention
