Description
Technical field
The invention belongs to endosseous implant technical field scope.In particular to the artificial dentistry implant of one.
Background technology
Before the sexcentenary in Christian era, Maya just brings into use endosseous implant technology.Until Per-Ingvar Branemark uses titanium as material, oral implantology is just that modern dentistry opens a brand-new field.Dental Implant as a kind of newly reliable and effective Oral Repair means, more and more receives the concern of people in stomatology field.
The tooth of healthy human body is connected with tooth socket bone wall by periodontal ligament; the dense connective tissue that in periodontal ligament, collagen fiber are formed makes tooth form an overhung construction in tooth socket bone wall; shock and vibration suffered when this overhung construction effectively can cushion tooth for chewing food; and it can be disperseed to pass to alveolar bone sting pressure, thus play and take care of one's teeth and the effect of alveolar bone.But due to modern times allegro life, people are negligent of the protection of tooth, many factors makes its pathological changes corrupted, thus affects tooth and chew behavior normally, finally has to adopt canine implant to replace nature tooth.
Existing canine implant technology first cuts tooth post ligament, is then screwed in alveolar bone by the implantation body of canine implant, finally by the prosthese corona part of canine implant by machinery or/and the mode of chemical bonding is fixed on implantation body.
Due to use frame for movement replace biological tissue formed overhung construction, dentistry implant inevitably by divide from crown portion sting pressure and impact shock be directly passed to alveolar bone.Research shows, alveolar bone can promote the differentiation of osteoclast when being subject to compressive stress, thus causes the bone resorption of alveolar bone.The loss of sclerotin directly has influence on the mechanical connection of alveolar bone and implantation body, thus affects the stability of implantation body, causes implantation body to loosen and loses efficacy.
Existing research and technology generally carries out design and optimization from material and structure two aspects to implantation body.1. material aspect: the implant part of Dental Implant widely uses pure titanium metal now, as:
the product Superline of company.Also the patent adopting titanium alloy is had, as: US 6238491B1, US 19990305881, EP 1206587A1.And adopt the patent of ceramic material, as: US 2008213726A1, JP 2008541960A, EP 20060741621, in addition use calcium phosphate ceramic in addition, such as hydroxyapatite (HA) and tricalcium phosphate (TCP) can improve the synosteosis ability of material.In addition, adopt process for treating surface in addition, as:
the bulky grain sandblasting of the S.L.A. Surface of the product I mplantium employing of company and acid etching technology; Nobel Biocare
the product of company
there is the highly crystalline of the perforate in nanometer range and to be rich in phosphatic titanium oxide be patterned surface.These are all the synosteosis abilities by using the mode of the material with good biocompatibility and the chemical property changing surface to improve implantation body and alveolar bone, thus improve the stability of implantation body.
2. configuration aspects: main Design of Main Structure (b) implant of consideration (a) implant part and the syndeton of base station design (c) anti-rotational structure and design (d) buffer shock-absorbing structural design
(a) in this regard, various taper and the implant part with various thread profile by extensive cognition, as: US5427527, this taper implant part is installed in cylinder osteotomy position to reduce the bone compression in its widest end.Also have and adopt the implant of two helicitic texture to increase synosteosis and to screw in efficiency, adopt fine thread to increase the contact area of cortical bone edge implant and osseous tissue at implant shoulder, strengthen the early stage fixing of cortical bone, as: the patents such as CN 101297772A.What adopt alterable screw thread can partly disperse occlusion load to produce answers a power apparatus, as: the patents such as US 5527183, US 5435723.In addition, also have by improving synestotic example to implant shoulder surface annular knurl, etching.
B () in this regard, the existing interpolation type of syndeton of implant part and base station also has outside plug type, the length of insertion portion affects transmission and the dispersion of gmatjpdumamics to a great extent.Outside plug type considers that the restriction of wearing gum height is general shorter in design, as: the products such as patent and Branemark, Osstem, Biohorizons such as US 6626911B1, US 6997711B2, US 2001004519A1.Interpolation type is less because considering that superstructure intensity designs insertion depth usually, as: the products such as patent and Alpha-bio, BEGO, Zimmer such as US 7249949B2, WO 2006109176A1, US 6283753B1, WO 2006088291A1.
C () in this regard, the structure that majority has rotation preventing function all designs near implant shoulder upper end open, easily gap is left like this after base station and implant part are assembled, for in cavity, virus and noxious bacteria provide the space grown, as: patent and the Nobel such as US 7108510B2, US 7309231B2, DE 20022420U1
deng product.In addition, also have putting of being connected with base station interpolation type of implant to revolve structure and adopt hexagon or eight-sided formation, the structure of such complexity equally easily grows virus and noxious bacteria, and for establishing angled base station to there is inconvenience when assembling, as: the products such as patent and Frialit-2, ITI such as US 20040209226A1, EP 1679049A1, US 6663388B1.
D () in this regard, current less patent and product consider the structural design of this respect, have employed of having arranges spring at implant intracavity, the coefficient of elasticity of spring can reduce in time on the one hand, thus affect the function of buffer shock-absorbing, seal not tight on the other hand at spring and base station contact jaw, the space stayed easily grows virus and noxious bacteria, as: the patents such as US 19730407244.Also have some to adopt elastic material or memory alloy material or elastomeric material to be filled in implant intracavity, such design can reduce implantation body's superstructure strength and stability, as: the patents such as US 5174755A, EP 1770302A1, US2009208904A1.In addition, these devices can not effectively reach the function of putting rotation while buffer shock-absorbing.
Summary of the invention
