Abstract
The utility model discloses an adjustable dental implant. The adjustable dental implant comprises a pile 1, a neck part 2 and a root part 3 from the top to the bottom, wherein the pile 1 is divided into an upper pile 4 and a lower pile 5, the upper pile 4 is of a solid cylinder structure, and the lower pile 5 is of a big end up solid conical structure; the upper pile 4 is provided with a flat plane tool interface 6; the circumference middle part of the neck part 2 is reduced, and the vertical section is of an arc shape; the root part 3 is of a big end up conical structure; a counter bore 7 is formed at the tail end of the root part in the axial direction, and a porous tantalum material is filled in the counter bore 7; a perforated hole 8 is formed at the tail end of the root part 3 in the radial direction, and a porous tantalum material is filled in the perforated hole 8; and the counter bore 7 and the perforated hole 8 are crossed in a T shape. According to the dental implant with the structure, the adjustability and adaptability can be reinforced, the biocompatibility of the structure can be improved, and the postoperative refresh cycle can be greatly shortened.
Description
Technical field
This utility model relates to a kind of tooth implant, relates in particular to that a kind of adjustability is high, strong adaptability, good biocompatibility, short tooth implant of restore cycle.
Background technology
There is poor, the not corrigibility shortcoming of adjustability in present tooth implant system.Be the problem that single-piece tooth implant or combination type tooth implant all exist foundation pile angle and form to be difficult to correct, be unfavorable for installing corona.
Simultaneously, even the corona installation because tooth implant material biocompatibility is not high, also as easy as rolling off a logly causes loosening or comes off.And because biocompatibility is not enough, tooth implant needs restore cycle of growing after implanting the oral cavity, could fully merge with body bone tissue.
The utility model content
In view of the foregoing defects the prior art has, this utility model aim to provide that a kind of adjustability is high, strong adaptability, good biocompatibility, short tooth implant of restore cycle.
To achieve these goals, this utility model by the following technical solutions: the adjustable type tooth implant is divided into foundation pile, cervical region and root from top to bottom; Described foundation pile is divided into foundation pile top and foundation pile bottom; Described foundation pile top is the solid cylinder body structure, and described foundation pile bottom is up big and down small filled circles cone structure; Described foundation pile top is provided with the flat horizontal surface tool interface; Described cervical region Zhou Jing middle part dwindles, and longitudinal section is circular arc; Described root is up big and down small conical structure; Described root end has counterbore vertically, is filled with the porous tantalum material in the described counterbore; Described root end radially has the hole of perforation, is filled with the porous tantalum material in the hole of described perforation; The hole of described counterbore and described perforation is " T " word and intersects.
As the improvement to the technical program, described root tapering is 10 °.
As the improvement to the technical program, described root outer surface belt screw thread.
Compared with the prior art, this utility model has strengthened the adjustability of tooth implant form owing to having adopted technique scheme, has improved the adaptability of tooth implant structure, has improved the biocompatibility of structure, has greatly shortened the restore cycle of postoperative.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment.
Among the figure: 1 foundation pile, 2 cervical regions, 3 roots, 4 foundation pile tops, 5 foundation pile bottoms, 6 flat horizontal surface tool interfaces, 7 counterbores, 8 holes that connect.
The specific embodiment
Below by embodiment this utility model is carried out concrete description; be necessary to be pointed out that at this following examples only are used for this utility model is further detailed; can not be interpreted as the restriction to this utility model protection domain, those skilled in the art can make some nonessential improvement and adjustment to this utility model according to foregoing.
Embodiment: a kind of adjustable type tooth implant, as shown in Figure 1, the adjustable type tooth implant is divided into foundation pile 1, cervical region 2 and root 3 from top to bottom; Described foundation pile 1 is divided into foundation pile top 4 and foundation pile bottom 5; Described foundation pile top 4 is the solid cylinder body structure, and described foundation pile bottom 5 is up big and down small filled circles cone structure; Described foundation pile top 4 is provided with flat horizontal surface tool interface 6; Middle part, described cervical region 2 week footpath dwindles, and longitudinal section is circular arc; Described root 3 is up big and down small conical structure; Described root 3 ends have counterbore 7 vertically, are filled with the porous tantalum material in the described counterbore 7; Described root 3 ends radially have the hole 8 of perforation, are filled with the porous tantalum material in the hole 8 of described perforation; The hole 8 of described counterbore 7 and described perforation is " T " word and intersects.
In order to strengthen the matching degree with the human body dental bed, preferred 10 ° of described root 3 taperings.
For the ease of implanting described root 3 outer surface belt screw threads.
Top Zhou Jing is larger for the tooth implant foundation pile, has larger ground leeway.After tooth implant was implanted, the doctor can grind foundation pile top as required in the oral cavity.The porous tantalum that root end is filled can strengthen the biocompatibility of structure, promotes the body bone tissue growth, the restore cycle after the desmopyknosis.
