Abstract
The micro thread implant includes one conic top with larger upper part and smaller lower part, one conic hole including one octagonal middle part and one lower screw hole part and surface coating of hydroxyapatite. It features the neck with fine thread, the root part with self-tapping straight thread and the conic end, with both the fine thread and the straight thread being saw tooth threads. The present invention has high neck strength, capacity of preventing microbes from invading, easy integrating with bone, easy screwing into the jaw bone and self locking, and may be used in repair dental defection, especially false tooth implanting operation.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly the micro thread implant of using about a kind of full jaw implant denture with biological sealing function.
Background technology
Oral implantology is an inter-trade medical skill that grows up nineteen sixties, relates to the complex art subject of medical science, electronics, machinery, material and biomechanics.Implant denture is the important component part in the oral implantology.Implant denture is widely used in the reparation of defect of dentition, disappearance, and the particularly application of full jaw implant denture for the serious patient who absorbs of alveolar ridge, has solved conventional artificial tooth and repaired more insurmountable problems.But also there are some problems in the success rate at a specified future date of implant denture, as the prolongation along with observing time, can occur the loosening of implantation body after the artificial tooth plantation and fractures, thereby cause planting the failure of prosthesis.Showing according to clinical observation, cause the reason that implantation body is loosening and fracture, mainly is that implantation body's design is unreasonable, its cervical region intensity is low, and in the implant operation process, antibacterial and microorganism enter easily in the cortical bone and cause difficulty and the failure that bone is integrated, and cause the loosening of implantation body at last.
Summary of the invention
At the problems referred to above, the purpose of this invention is to provide the micro thread implant that a kind of full jaw implant denture is used with biological sealing function.
For achieving the above object, the present invention takes following technical scheme: a kind of micro thread implant, the top of implantation body is a up big and down small round platform, described round platform top inwardly offers a taper hole, at described taper hole middle part hole, all directions in is set, described taper hole bottom is extended a screw vertically, described implant surface scribbles hydroxyapatite coating layer, it is characterized in that: the cervical region of described implantation body is provided with fine thread, described implantation body root is a straight thread, described straight thread end has tapering, and has the self tapping cutting slot, and described fine thread and straight thread are saw-tooth thread.
Angle between the inclined plane of described fine thread and the back pressure face is 70 °, and the angle between back pressure face and the vertical is 10 °.
The inclined plane of described straight thread profile of tooth and the angle between the vertical are 70 °, and the angle between back pressure face and the vertical is 16 °.
Described self tapping cutting slot is three of 120 ° of settings of being separated by.
The tapering of the intravital taper hole of described plantation is less than 8 °, and described implantation body inner bolt hole diameter is 2mm.
The diameter of described fine thread is 3.7mm, and pitch is 0.3mm, and tooth depth is 0.15mm.
The present invention is owing to take above technical scheme, and it has the following advantages: 1, therefore the present invention can increase the contact area of the implantation body and the face of implantation effectively owing to be provided with fine thread at implant neck, is very beneficial for implant osseointegration.2, the present invention is equivalent to the labyrinth sealing mechanism in the Machine Design at the fine thread that implant neck adopts, and can prevent effectively that therefore microorganism and other pollutant from immersing, and is very beneficial for the healing rehabilitation of the face of implanting.3, the present invention is owing to the cervical region in implantation body has adopted fine thread, particularly adopt the screw thread at the specific zigzag angle of inclination of the present invention, its pitch is short, tooth depth is shorter than standard thread, therefore than the cervical region intensity height of the implantation body of other structure, the implantation body that has solved anistree taper hole in the present design band runs into the difficult problem of cervical region insufficient strength, and successfully producing diameter is the implantation body of the interior anistree taper hole of band of 3.7mm.4, therefore the present invention can make implantation body more easily screw in the oral cavity jawbone, and by the self-locking action that buttless thread has, guarantee that under the effect that is not subjected to external force, screw thread can not become flexible owing to adopt special type buttless thread at implantation body's root.5, therefore the present invention can make implantation body cut the oral cavity jawbone easily, and help the first location of implantation body owing to the self tapping cutting slot that has tapering root being provided with of implantation body.The present invention can be widely used in the reparation of various defect of dentition, disappearance, particularly in the operation of full jaw implant denture.

The specific embodiment
Below by drawings and Examples, the present invention is described in detail.
As shown in Figure 1, the present invention is the non-baried type tooth implant of a kind of two-period form, the implantation body top is a up big and down small round platform 1, round platform 1 top has chamfering 2, the bottom of round platform 1 is that the cervical region of implantation body is the fine thread 3 that one section diameter is 3.7mm, the pitch of fine thread 3 is 0.3mm, and tooth depth is 0.15mm.And then the bottom of fine thread 3 is that the root of implantation body is a straight thread 4, and the end of straight thread 4 has tapering, and has three self tapping cutting slots 5 (as shown in Figure 2), three 120 ° of settings in self tapping cutting slot 5 spaces.As Fig. 1, shown in Figure 3, a taper hole 6 is inwardly offered at round platform 1 top of implantation body, and the tapering of taper hole 6 is less than 8 °.At taper hole 6 middle parts hole 7, all directions in is set, extends a screw 8 vertically in taper hole 6 bottoms, the base station location when being used to perform the operation and fixing, screw 8 diameters are 2mm.Implant surface is same as the prior art, scribbles hydroxyapatite (HA) coating.
As shown in Figure 4, the fine thread 4 of implant neck of the present invention is a saw-tooth thread, and the angle between the inclined plane of this saw-tooth thread and the back pressure face is 70 °, and the angle between back pressure face and the vertical is 10 °.As shown in Figure 5, the screw thread 4 of implantation body's root also is a saw-tooth thread, and the inclined plane of this saw-tooth thread and the angle between the vertical are 70 °, and the angle between back pressure face and the vertical is 16 °.Each above-mentioned angle can change in 1～2 ° scope.Adopt the saw-tooth thread of the special type of the present invention, when implantation body screws in the oral cavity jawbone (as shown in Figure 6), being equivalent to A moves along the inclined plane S direction of sawtooth, being equivalent to B when implantation body is loosening moves along the inclined-plane M of sawtooth, when the α angle more hour, A moves along the S direction more easily, and when the α angle increased, it is more difficult that A moves along the S direction; Same cause, B is more difficult when becoming flexible in implantation body rises.
Described above is a specific embodiment of the present invention; wherein many concrete sizes are in order to realize that implantation body's diameter is 3.7mm (recess diameter) and specially being provided with; when carrying out other diameter dimension design of cervical region; above-mentioned each concrete physical dimension can change; the variation of this size should not got rid of outside protection scope of the present invention.
