Description
Technical field
The invention belongs to oral cavity medical apparatus technical field, relate to tooth implant.
Background technology
Since nineteen sixty-five Branemark takes the lead in pure-titanium tooth implantation is applied to clinic, along with material with
The development of medical skill, the application of tooth-planting is more and more extensive, but the most usually meets in actual application
The problems such as and bone regeneration around implant infection bad to the Bone mineral change (height and thickness) of patient, implant retention.
In recent years, the progress of digital medical technology, the development for prosthetic dentistry provides a new approach.
Utilize digitizing technique to carry out corona and the three dimensional design of prosthesis and making, and become tooth and Maxillofacial defect is repaiied
One of important development direction gone back to school.Particularly computer-aided design/Computer aided building (CAD/CAM)
It is widely used to the making of oral cavity zirconium oxide prosthesis in recent years.But for dentistry implant, apply at present
The commodity of finished product, the most not yet occurring being similar to commercialization dental CAD/CAM system like that can be with pin
To the most patient personalized implantation body's product.
Summary of the invention
The present invention seeks to for current mouth cavity planting body Malretention, peri-implantitis and some patients jaw
The situations such as bone Bone mineral change and the wing implantation body that designs, this wing surface of jawbone around covers implants,
Increase the contact area of implantation body and bone, increase maintenance and the holding strength of implantation body, effectively prevent implantation body
The generation of inflammation around.And personalized wing implantation body can design according to the practical situation of patient, can be effective
Improve the indication of implantation body.This wing can become discoid or irregularly shaped, jaw around covers implants
The surface of bone.
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, it is characterised in that the body (1) of implantation body exists
The periphery of jawbone surface is provided with fin (2).The body (1) of fin and implantation body is integrated, fin (2)
The length of fin (2) it is referred to as from the outward extending length in laminating jawbone surface, the surface of the body (1) of implantation body
Degree, fin is the most thinning from the outside thickness of body (1) i.e. airfoil root of implantation body；The preferably body of implantation body
The fin (2) of portion (1) surrounding is an overall continuous print closure flaps, as discoid.
The length of the wing can design 1.0-5.0mm, the thickness of the wing and the junction of implantation body according to the practical situation of patient
0.5-2.0mm, 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 personalized implantation body or the impersonal theory implantation body of winged of winged.
The wherein personalized implantation body of (1) winged: this implantation body can utilize computer-aided design/calculating
Machine secondary process (CAD/CAM) system, it is possible to should utilize the technology such as laser sintering technology or 3-D printing, needs
Applied Digital technology is wanted to carry out three-dimensional data scanning, the three dimensional design of implantation body's body and the numerical control of implantation body
Processing.Firstly, for oral cavity jawbone three-dimensional data scan, mainly use layer scanning technology, including CT,
MRI scan technology.Utilize different physical principles successively to scan testee and obtain the X-Y scheme of many levels
Picture, these images contain the complete information of each cross section profile and internal feature thereof, then pass through three-dimensional reconstruction
Software obtains the threedimensional model that object is complete.Then, utilize digitizing technique according to the three-dimensional shaped of patient's jawbone
State can accurately design suitable diameter and the implantation body of length, the Er Qiegen meeting patient's practical situation
According to the situation on patient's jawbone surface design close with jawbone surface and the wing, finally make implantation body reach closely sealed solid
Position.Finally, prepared by technology such as machining, laser sintering technology or 3-D printings that to meet patient actual
The personalized wing implantation body of situation.Owing to the wing of this implantation body and the contact surface of jawbone are irregular shape, with
The fitness of jawbone surface is good, is difficult to rotate in place, and the surface of implantation body is designed as smooth type.Personalized plantation
The wing of body and jawbone contact surface are the form Designs according to jawbone surface, close with jawbone surface and, the length of the wing
Degree can design 1.0-5.0mm, the thickness of the wing and the junction of implantation body according to the practical situation of patient
0.5-2.0mm, is extended to the bladed of edge.
(2) the impersonal theory implantation body of winged: the design of this wing produces in batch with conventional mechanical cutting processing.
The contact surface of the wing and jawbone be regular shape, can rotate in place, but the most in place needs the jawbone below the wing
Surface carries out suitable finishing, so implant surface can be smooth type and screw-type.Impersonal theory implantation body
The face of the wing and jawbone contact surface 0-45 degree, the length of the wing can design 1.0-5.0mm, the thickness of the wing and plantation
The junction 0.5-2.0mm of body, is extended to the bladed of edge.
Wing implantation body material can be pottery or metal material.
Wing implantation body can be one-part form or two-part；Described one-part form is the implantation body of band fin (2)
Body (1) with wear gum portion (4), abutment portion (5) is integrated；Described two-part is band fin (2)
The body (1) of implantation body and to wear between gum portion (4) be separate.
Wing implant surface can be modified by various methods, to improve its biocompatibility.
The mouth cavity planting body of winged of the present invention can be effectively improved the indication of implantation body, adds implantation body and bone
Bonded area, improves holding strength the most at a specified future date, resists bigger masticatory pressure, can be effectively increased kind
The maintenance of implant and can effectively prevent the infection of bone regeneration around implant.This implantation body can utilize digitizing technique,
Design personalized wing implantation body more can be suitable for the practical situation of patient, it is to avoid because the Bone mineral change of patient is (high
Degree and thickness) and need bone grafting the situation such as maybe cannot plant, can further improve the success rate of implantation body；Also
Can conventional mechanical cutting processing produce in batch.The invention provides a kind of novel mouth cavity planting body.
