Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail, it is to be understood that protection domain of the present utility model is not by the restriction of detailed description of the invention.
Explicitly indicate that unless otherwise other, otherwise in entire disclosure and claims, term " includes " or its conversion will be understood to comprise the element or ingredient stated at such as " comprising " or " including " etc., and does not get rid of other element or other ingredient.
As shown in Figure 1, baried type implantation body according to this utility model detailed description of the invention constitutes a whole set of structure with base station main body, base station fastening screw three part, have stress dispersion, bearing load is strong, the uniform feature of cutting force, it is easy to primary stability, is conducive to bone union process.The concrete structure of this baried type implantation body includes: root screw thread 11, cervical region fine thread 12 and foundation pile portion 13, and screwed hole of centre.Wherein, the external diameter of root screw thread 11 is Φ 3.3mm, and pitch is 0.8mm；The external diameter of cervical region fine thread 12 is 3.6mm, and pitch is 0.2mm；Foundation pile portion 13 is outer six side's designs, and screwed hole of centre is M1.8, and the base station supporting with it is connected.This baried type implantation body can adapt to the feature of China patient tooth jawbone, retain the design of general implantation body screwed hole of centre, and the connection mechanical strength of implantation body and base station will not be reduced, change the interior connection design of tradition implantation body into outer connection, improve connective stability and the convenience of implantation body and base station, support the use with corresponding base station, form a rounded system, to adapt to the demand of different patient.
Specifically, as in figure 2 it is shown, root screw thread 11 is saw-tooth thread, its external diameter is Φ 3.3mm, and the angle [alpha] between inclined plane and back pressure face is 60 degree, and pitch a is 0.8mm, and thread depth h1 is 0.3mm.Monnolithic case of the present invention is wide at the top and narrow at the bottom, root major diameter of thread is Φ 3.3mm, adapt to the needs of our asian population, saw-tooth thread (Fig. 3) design improves the self tapping performance of implantation body, make to screw in during operation to be more prone to, add the contact surface of implantation body and jawbone, be conducive to implant osseointegration, can improve and the synestotic efficiency of jaw, moreover it is possible to anti-rotation is to improve surgical quality.
The outer surface spraying hydroxyapatite of root screw thread 11, promotes and the combination of bone more, makes the healing at initial stage and compatible is more prone to.Tooth Shape Design considers that loosing prevention designs, and makes implantation body avoid and loosens because using time length.
As it is shown on figure 3, cervical region fine thread 12 is saw-tooth thread, its external diameter is Φ 3.6mm, and the angle beta between inclined plane and back pressure face is 50 degree, and pitch b is 0.2mm, and thread depth h2 is 0.1mm.Cervical region fine thread is equivalent to the labyrinth sealing mechanism in Machine Design, it is possible to effectively prevent the immersion of microorganism and other pollutant, it is appreciated that implant the healing in face in implantation body.And the external diameter of fine thread increases to some extent than the external diameter of heel, it is increased by the intensity of whole implantation body, reduces the ratio of operative failure owing to implantation body's intensity is low.
Foundation pile portion 13 is outer positive six square toes designs, is connected with six sides in the base station main body of Aided design, and anti-rotation performance improves, and makes operation simple and convenient.Outer six side's designs on this utility model top, it is by Innovation of Connection in traditional implantation body, avoid traditional narrow implantation body makes center bolt reduce accordingly and risk that intensity is substantially reduced owing to external diameter is little, thus substantially increasing the bond strength of implantation body and base station, anti-fatigue performance is greatly enhanced.
Screwed hole of centre is M1.8 screwed hole, is connected with the screw thread of the fastening screw of Aided design base station, reaches the purpose of plantation, and ensure that the bonding strength of implantation body and base station, and fatigue resistance is greatly enhanced.The interior screwed hole of centre of implantation body of the present invention to reduce because of the change of external diameter, still continues to use international conventional M1.8 design, it is ensured that the bonding strength of implantation body and supporting base station.
To sum up, this baried type implantation body can adapt to the feature of China patient tooth jawbone, retain the design of general implantation body screwed hole of centre, and the connection mechanical strength of implantation body and base station will not be reduced, change the interior connection design of tradition implantation body into outer connection, improve connective stability and the convenience of implantation body and base station, support the use with corresponding base station, form a rounded system, to adapt to the demand of different patient.
The aforementioned description to specific illustrative embodiment of the present utility model illustrates that and the purpose of illustration.These describe and are not wishing to be defined to this utility model disclosed precise forms, and it will be apparent that according to above-mentioned instruction, it is possible to carry out much changing and change.Purpose exemplary embodiment selected and describe is in that to explain certain principles of the present utility model and practical application thereof, so that those skilled in the art is capable of and utilizes various different exemplary of the present utility model and various different selection and change.Scope of the present utility model is intended to be limited by claims and equivalents thereof.
