Description

A kind of mouth cavity planting body with fin
Technical field
The invention belongs to oral cavity medical apparatus technical field, relate to tooth implant.
Background technology
Since nineteen sixty-five Branemark take the lead in pure-titanium tooth implantation to be applied to clinical since, development along with material and medical skill, the application of tooth-planting is more and more extensive, but in actual application, also usually run into patient bone quantity not sufficient (height and thickness), implant retention is bad and the problem such as bone regeneration around implant infection.
In recent years, the progress of digital medical technology, for the development of prosthetic dentistry provides a new approach.Utilize digitizing technique to carry out three dimensional design and the making of corona and prosthesis, and become one of important development direction of tooth and Maxillofacial defect prosthodontics.Particularly computer-aided design/area of computer aided processing (CAD/CAM) has been widely used in the making of oral cavity zirconium oxide prosthesis in recent years.But for dentistry implant, the commodity of the finished product of applying at present, not yet occurring being in the world similar to commercialization dental CAD/CAM system like that can be for implantation body's product of concrete patient's personalization.
Summary of the invention
The present invention seeks to the with Yi implantation body designing for situations such as current mouth cavity planting body Malretention, peri-implantitis and some patients were jaw bones quantity not sufficients, this wing is for the surface of jawbone around covers implants, increase the contact area of implantation body and bone, the maintenance and the holding strength that increase implantation body, effectively prevent the generation of bone regeneration around implant inflammation.And the indication of implantation body can, according to patient's practical situation design, can effectively improve in personalized with Yi implantation body.It is discoid or irregularly shaped that this wing can become, for the surface of jawbone around covers implants.
For achieving the above object, the technical solution used in the present invention is as follows.
A kind of mouth cavity planting body with fin of the present invention, is characterized in that, the periphery of the body of implantation body (1) in jawbone surface is provided with fin (2).The body of fin and implantation body (1) is integrated, fin (2) is called the length of fin (2) from the outward extending length in the surface of the body (1) of implantation body laminating jawbone surface, fin is the attenuation gradually of the outside thickness of fin root from the body (1) of implantation body; Preferably the fin (2) of body (1) surrounding of implantation body is a whole continuous closure flaps, as discoid.
The length of the wing can be according to patient's practical situation design 1.0-5.0mm, the junction 0.5-2.0mm of the thickness of the wing and implantation body, and being extended to edge is bladed.The surface of implantation body is smooth type and screw-type.
Mouth cavity planting body described above can be with the personalized implantation body of the wing or with the non-personalized implantation body of the wing.
Wherein (1) is with the personalized implantation body of the wing: this implantation body can utilize computer-aided design/area of computer aided processing (CAD/CAM) system, also can utilize the technology such as laser sintered technology or 3-D printing, need Applied Digital technology to carry out three-dimensional data scanning, the three dimensional design of implantation body's body and the digital control processing of implantation body.First, for the scanning of oral cavity jawbone three-dimensional data, be mainly to adopt layer scanning technology, comprise CT, MRI scanning technique.Utilize different physical principles successively to scan the two dimensional image that testee obtains many levels, the complete information that these images have comprised each cross section profile and internal feature thereof, then by the threedimensional model of three-dimensional reconstruction software acquisition complete object.Then, utilize digitizing technique can accurately design and meet the suitable diameter of patient's practical situation and the implantation body of length according to the three-dimensional configuration of patient's jawbone, and according to the situation on patient's jawbone surface design close with jawbone surface and the wing, finally make implantation body reach closely sealed maintenance.Finally, by technology such as machining, laser sintered technology or 3-D printings, prepare the personalized with Yi implantation body that meets patient's practical situation.Because the wing of this implantation body and the contact surface of jawbone are irregular shape, good with jawbone surface fitness, be difficult for rotating positioning, the surface design of implantation body is smooth type.The wing of personalized implantation body and jawbone contact surface are according to the form Design on jawbone surface, with jawbone surface close and, the length of the wing can be according to patient's practical situation design 1.0-5.0mm, and the junction 0.5-2.0mm of the thickness of the wing and implantation body is extended to the bladed of edge.
(2) with the non-personalized implantation body of the wing: the design of this wing is produced in batch with conventional mechanical cutting processing.The contact surface of the wing and jawbone is regular shape, can rotating positioning, but finally in placely need to carry out suitable finishing to the jawbone surface below the wing, so implant surface can be smooth type and screw-type.The face of the wing of non-personalized implantation body and jawbone contact surface 0-45 degree, the length of the wing can design 1.0-5.0mm, and the junction 0.5-2.0mm of the thickness of the wing and implantation body is extended to the bladed of edge.
With Yi implantation body material can be pottery or metal material.
With Yi implantation body can be one-part form or two-part; Described one-part form for band fin (2) implantation body body (1) with wear gum portion (4), abutment portion (5) is integrated; Described two-part is what to separate for being with the body (1) of the implantation body of fin (2) with wearing between gum portion (4).
With wing implant surface can be passed through the whole bag of tricks modification, to improve its biocompatibility.
The mouth cavity planting body of the band wing of the present invention can effectively improve the indication of implantation body, increased the bonded area of implantation body and bone, improved the early holding strength in long term, resisted larger masticatory pressure, can effectively increase the maintenance of implantation body and can effectively prevent the infection of bone regeneration around implant.This implantation body can utilize digitizing technique, design personalized with Yi implantation body more can be applicable to patient's practical situation, avoid bone quantity not sufficient because of patient (height and thickness) to need bone grafting the situation such as maybe cannot plant, can further improve the success rate of implantation body; Also can also can conventional mechanical cutting processing produce in batch.The invention provides a kind of novel mouth cavity planting body.
