Abstract
The utility model discloses a dental implant. The dental implant comprises a body part (1), a neck part (2) and a base platform (3), wherein the body part (1) and the neck part (2) are integrated and made of a gradient porous tantalum material; one end of the body part (1) and the neck part (2) are made of porous tantalum with the porosity of 20 to 30 percent; and the other end, which is connected with the neck part (2), of the body part (1) is made of porous tantalum with the porosity of 60 to 70 percent. The dental implant has excellent biocompatibility, is made of the gradient porous tantalum material, and also meets the requirements of mechanical properties at the same time; when the dental implant is implanted into alveolar bone, slight grooves or indentations can be formed by the grinding and filing actions on hole walls of the porous tantalum material, and help to limit the rotation or the torsion of the implant; meanwhile, the osseointegration on the implant and the porous material is facilitated because the porous material is impacted by the bone; and the dental implant is high in biocompatibility and has a long service life.
Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of manual tooth planting's body of good biocompatibility.
Background technology
Behind the absence of tooth, can adopt multiple mode to cure in the human mouth, for example, dental filling, have a denture made etc.
Over past ten years, along with science and technology development, stomatology has also had significantly progressive, cures anodontia even can plant.Oral dental implant mainly is made up of body, cervical region and base station three parts; Body is that implantation body screws in the part in the tissue; Cervical region be base station the latter half, work to connect body and base station; Base station is that implantation body is exposed to the outer part of alveolar bone and mucosa, for the artificial artificial tooth of its superstructure provides support, maintenance and Stabilization.In the last mandibular bone (alveolar bone) of operating mode with its implant into body agomphosis position, treat its operation wound heal after, install to repair the device of artificial tooth at an upper portion thereof.The process of this kind treatment oral cavity anodontia is called plants tooth or plants tooth; Implantation body's implant surgery divided for two phases accomplished; Usually adopt two-part helicity titanium implant; The body cylindrical that two-part screw type titanium implant screws in the tissue need be processed into tapping screw thread, and body connects with all adopting shaping connecting of cervical region.
At present generally adopt titanium or titanium alloy, thereby grown it and repelling the service life that influences tooth implant can appear in tissue for metal material, time as manual tooth planting's body material.
The utility model content
The purpose of this utility model is to provide a kind of and the human-body biological compatibility is good, manual tooth planting's body of long service life.
The purpose of this utility model realizes through following technical scheme:
A kind of tooth implant; Comprise body, cervical region and base station; It is characterized in that: said body and cervical region are one of the forming, adopt gradient porous tantalum material; Wherein an end of body, cervical region employing porosity are 20 ~ 30% porous tantalum, and the body other end that links to each other with cervical region employing porosity is 60 ~ 70% porous tantalum.
Above-mentioned porous tantalum can adopt preparations such as foam dipping method, die pressing; Adopt above-mentioned gradient porous tantalum material not only reached tooth implant mechanical property requirements, but also improved the biocompatibility of tooth implant greatly; Human body dentale tissue infiltrates in the hole of porous tantalum, the service life of having improved this tooth implant greatly.Base station adopts titanium or titanium alloy material.
Further, above-mentioned employing porosity is 20 ~ 30% porous tantalum materials body end accounts for 1/3 of body length.
For the further roughness that improves the porous tantalum material surface, thereby when tooth implant is implanted alveolar bone, improve the grasping force between implantation body and skeletal tissue, above-mentioned porous tantalum body adopts thread profile.
The cervical region of above-mentioned tooth implant can adopt sintering to be connected with base station, hollow platform awl, base station lower surface also can be set in middle part, cervical region upper surface a platform awl is set makes that cervical region and base station are inserted to be connected.
In order to collect broken kindred tissue residue, to be beneficial to osseous tissue and to get in the porous tantalum more quickly and grow, also hole slot is set at above-mentioned body.
Improve intensity in order to reduce stress, above-mentioned hole slot preferably is arranged on and adopts porosity is the body one end end face central authorities of 20 ~ 30% porous tantalum.
The utlity model has following beneficial effect:
This utility model tooth implant has excellent biocompatibility; Adopt gradient porous tantalum material also to satisfy mechanical property requirements simultaneously; When tooth implant is implanted alveolar bone on the hole wall of porous tantalum material mill frustrate action and can form slight groove or indentation; Help limit the rotation of planting body or reverse,, help to carry out the bone integration on body and the porous material planting simultaneously also because of bone impacts porous material; Good, the long service life of this utility model tooth implant bio-compatibility.
Description of drawings
Fig. 1 is the structural representation of this utility model tooth implant preferred embodiment; Wherein, 1 body, 2 cervical regions, 3 base stations, 4 hole slots.
The specific embodiment
Being this utility model preferred embodiment below, is not the protection domain that is used to limit this utility model.
Referring to accompanying drawing 1; A kind of tooth implant comprises the body that is wholely set 1 and cervical region 2, is provided with base station 3 at the other end of cervical region; This implantation body adopts gradient porous tantalum material; Wherein an end of body 1 and cervical region 2 employing porositys are 20 ~ 30% porous tantalum, and the body end of the porous tantalum of these employing 20 ~ 30% porositys accounts for 1/3 of body 1 length, and the porosity of the porous tantalum that body 1 other end that links to each other with cervical region 2 adopts is 60 ~ 70%; Said porous tantalum body 1 adopts thread profile, adopts the body end end face central authorities of the porous tantalum of 20 ~ 30% porositys to be provided with hole slot 4; The cervical region 2 of said tooth implant adopts sintering to be connected with base station 3.
Claims (5)
