CN203107315U - Dental implant with screw thread - Google Patents

Abstract

The utility model discloses a dental implant with a screw thread. The dental implant with the screw thread comprises a body 1; the upper part of the body 1 is cylindrical; the lower part of the body 1 is conical; a trapezoidal screw thread 2 is formed on the outer side of the cylinder on the upper part of the body 1; the end of the lower part of the body 1 is provided with a horizontal through hole 3 and a vertical hole 4; the horizontal through hole 3 is crossed with the vertical hole 4 to form a T shape; porous tantalum is filled in the horizontal through hole 3 and the vertical hole 4; and a nano-apatite filling part 5 is formed on the lower conical part of the body 1. By the dental implant with the structure, the biocompatibility of the dental implant is enhanced, so that the dental implant is more stable and a person feels more comfortable after the dental implant is implanted; the postoperative recovery time is shortened; and the implanting effect is improved.

Description

A kind of threaded tooth implant

Technical field

This utility model relates to a kind of threaded tooth implant, relates in particular to the threaded tooth implant that a kind of comfortableness is good, biocompatibility is high, repair time is short.

Background technology

The tooth planting technology has obtained extensive use clinically as a kind for the treatment of and reparation tooth effective ways damaged or anodontia, has vast potential for future development.Tooth implant has fundamental influence as a big critical component of tooth planting technology to the success or failure of planting.There are many defectives in existing tooth implant, as the biocompatibility deficiency, comfort is poor, repair time is long etc., and postoperative effect is had a greatly reduced quality.

The utility model content

At the above-mentioned defective that prior art exists, this utility model aims to provide the threaded tooth implant that a kind of comfortableness is good, biocompatibility is high, repair time is short.

To achieve these goals, this utility model by the following technical solutions: threaded tooth implant comprises body; Described body top is cylindrical, and the bottom is conical; The cylinder outside, described body top has trapezoidal thread; Described body lower end headband has horizontal through hole and upright opening, and described horizontal through hole and upright opening intersect and be " T " shape, are filled with porous tantalum in described horizontal through hole and the upright opening; Described body lower cone is provided with nano-apatite and fills the position.

As the improvement to the technical program, described trapezoidal thread tooth form angle is 60 °.

As the improvement to the technical program, described body lower cone tapering is 30 °.

Compared with the prior art, this utility model has strengthened the biocompatibility of tooth implant owing to adopted technique scheme, and is more firm comfortable after tooth implant is implanted, and shortened postoperative repair time, promoted planting effect.

Description of drawings

Fig. 1 is the structural representation of this utility model embodiment.

Among the figure: 1 body, 2 trapezoidal threads, 3 horizontal through hole, 4 upright openings, 5 nano-apatites are filled the position.

The specific embodiment

Carry out concrete description below by this utility model of embodiment; 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 threaded tooth implant, as shown in Figure 1, threaded tooth implant comprises body 1; Described body 1 top is cylindrical, and the bottom is conical; The cylinder outside, described body 1 top has trapezoidal thread 2; Described body 1 lower end headband has horizontal through hole 3 and upright opening 4, and described horizontal through hole 3 and upright opening 4 intersect and be " T " shape, are filled with porous tantalum in described horizontal through hole 3 and the upright opening 4; Described body 1 lower cone is provided with nano-apatite and fills position 5.

Preferred 60 ° of described trapezoidal thread 2 tooth form angles.

For fully adapting to organization of human body, preferred 30 ° of described body 1 lower cone tapering.

Trapezoidal thread can be strengthened interlocking, helps the enhancing of tooth implant steadiness.Be cylinder on the tooth implant, be the architectural feature of circular cone down, with human body matching degree height, strengthened the comfort of human body.The porous tantalum of high-biocompatibility and nano-apatite can start bone tissue growth, the molding of guiding sclerotin, accelerate healing, shorten repair time; Simultaneously, also can promote bony fusion, eliminate foreign body sensation, promote comfortableness.
