Abstract
The utility model relates to a metal tooth root used for being embedded to a teethridge, which comprises a teethridge implant and is characterized in that the teethridge implant consists of a front implant made of medical compact-state metal material and a rear implant made of medical porous titanium nickel base shape memory alloy; the rear part of the rear implant is provided with a diameter-contracted screw; the outside of the diameter-contracted screw is provided with outside threads; the central part of the front end face of the front implant is provided with a screw hole; the rear body is screwed to the screw hole of the front implant through the screw of the other end and connected with the front implant. The metal tooth root solves the problems that the prior medical compact-state tooth root implant has high elastic modulus, can not realize the ideal tissue growth and firm fixing, etc.
Description
Technical field
This utility model relates to the new device of human body root of the tooth implant.
Background technology
Owing to reasons such as pathological changes or wounds, the implantation that has a lot of people need carry out root of the tooth improves life quality.Traditional fine and close attitude root of the tooth implant adopts medical pure titanium, titanium alloy metal materials such as (as Ti6Al4V) to make, because the elastic modelling quantity of the metal material of fine and close attitude is higher than human teeth's elastic modelling quantity far away, can forms " stress shielding effect " after the implantation and cause problems such as osteoporosis; And, tissue causes tooth root loosening even problem such as come off because can not growing into fine and close attitude metal.
Summary of the invention
This utility model easily causes osteoporosis and loosening problem in order to solve the existing root of the tooth of implanting, and a kind of metal root of the tooth that is used to implant in the dental bed is provided.
The technical scheme that adopts is:
A kind of metal root of the tooth that is used to implant in the dental bed, comprise the root of the tooth implant, it is characterized in that described root of the tooth implant is that preceding implant of being made by medical fine and close attitude metal material and the back implant of being made by the Ni-based marmem of medical porous titanium constitute, the rear portion of described back implant has the undergauge screw rod, and the outside of this undergauge screw rod has external screw thread; The center of the front end face of implant has screw before described; Before being screwed into, the screw rod of back Yue main body by other end interconnect in the screw of implant.
Above-mentioned medical fine and close attitude metal material is pure titanium or titanium alloy;
The Ni-based marmem of above-mentioned medical porous titanium is porous titanium nickel alloy or POROUS TITANIUM nickel-molybdenum alloy or POROUS TITANIUM dilval.
This utility model had both utilized the surrender of the fine and close attitude metal material of conventional medical, tension, characteristics that fatigue strength is good, the characteristics of having utilized the three-dimensional communication pore structure of medical whole POROUS TITANIUM Ni-based marmem and elastic modelling quantity and osseous tissue to mate again.Guaranteeing under the prerequisite of mechanical performance, can guarantee better that tissue problem, raising root of the tooth implantation quality such as grows into, fix.Particularly earlier with the part of the Ni-based marmem of medical porous titanium, help the growing into of conveying, tissue of human body fluid and nutrient substance, thereby realize the secure fixation of implant as the root of the tooth implant.It has the three-dimensional communication similar to the human body spongy bone the reticulated cell gap structure, with the ess-strain shape of human body hard tissue be super-elasticity that is complementary and mechanical property and the elastic modelling quantity that is complementary with sclerous tissues, good biocompatibility.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of this utility model.
The specific embodiment
A kind of metal root of the tooth that is used to implant in the dental bed, comprise root of the tooth implant 1, be characterized in that root of the tooth implant 1 is the preceding implant 2 made by medical titanium alloy Ti6Al4V and is made of the back implant 3 that the medical porous titanium nickel-molybdenum alloy is made, the rear portion of back implant 3 has undergauge screw rod 4, and the outside of this undergauge screw rod 4 has external screw thread; The center of the front end face of preceding implant 2 has screw 5; Before being screwed into, the undergauge screw rod 4 of back implant 3 by its rear end interconnect in the screw 5 of implant 2.
Claims (3)
1, a kind of metal root of the tooth that is used to implant in the dental bed, comprise the root of the tooth implant, it is characterized in that described root of the tooth implant is that preceding implant of being made by medical fine and close attitude metal material and the back implant of being made by the Ni-based marmem of medical porous titanium constitute, the rear portion of described back implant has the undergauge screw rod, and the outside of this undergauge screw rod has external screw thread; The center of the front end face of implant has screw before described; Before being screwed into, the screw rod of back Yue main body by other end interconnect in the screw of implant.
2, a kind of metal root of the tooth that is used to implant in the dental bed according to claim 1 is characterized in that described medical fine and close attitude metal material is pure titanium or titanium alloy.
3, a kind of metal root of the tooth that is used to implant in the dental bed according to claim 1 is characterized in that the Ni-based marmem of described medical porous titanium is porous titanium nickel alloy or POROUS TITANIUM nickel-molybdenum alloy or POROUS TITANIUM dilval.
