In one embodiment of the invention:

the invention meets the technical problems of long processing period, more data which need to be measured in advance, large processing difficulty, high requirement on equipment and improvement of the overall operation difficulty of the greenling technology in the prior art; the technical means that the greenling dental implant is completely detached, the part which needs to be customized according to the gum parameter of the patient and the part which needs to have high assembly precision requirement are completely separated, the parts are processed separately, and the processing mode is improved pertinently according to the requirements of the respective parts of the layout; the technical means follows the rule that the part which needs individuation is processed separately, the problem of excessively considering the processing precision is not needed, and the processing difficulty of the individuation shape and the structure is not needed to be considered for processing the part with the processing precision, so that the processing flow is simplified; obtained the machining efficiency that has improved whole greenling tooth of growing, reduced the processing degree of difficulty, simplified the structure of processing part, increased the technological effect of machining precision, specifically as follows:

the existing greenling bridge dental implant is an existing implant 1, a base station and a greenling bridge 5 are machined, for the sake of integral rigidity, an integral structure is used, very high machining precision is needed when the implant 1 and the base station are machined, particularly, the base station plays a role in connection, the machining precision requirement is highest, the greenling bridge 5 needs to be installed on the upper surface and needs to be adhered, and the lower surface is locked on the implant 1 through threads, so that the whole structure needs to be machined by using a CNC (computer numerical control) machine tool with more than 5 shafts; the fixture is used for ensuring the machining precision and avoiding the installation deviation when the fixture is installed on the alveolar bone, because the deviation of the structure cannot be corrected and can only be manufactured again.

The embodiment of the invention provides a Malong bridge implant of a split abutment and an assembly method thereof, and solves the technical problems that: 1. because the structural requirement of the base station is too high, the upper half part needs to be precisely matched with the greenling bridge 5, and the lower half part needs to be precisely installed with the implant 1, in order to ensure the precision and lose the processing speed, the existing equipment for processing the greenling bridge dental implant has low efficiency, one set can be manufactured generally in ten hours, and only one set can be manufactured at a time; 2. when the numerical control machine tool is used for processing parts, the simpler the structure of the parts is, the smaller the processing difficulty is, and because the structural requirement of the existing base station for the greenling bridge is more complex, the processing difficulty is large, the equipment required to be used is more complex, and the processing precision is more difficult to control; 3. each greenling dental implant must be customized according to the gingiva of a patient, too many parts of the existing greenling dental implant are customized individually, the processing time is too long due to no simplification, the gum inflammation is easily caused due to too long waiting time after the alveolar bone of the patient is drilled, and the main reason of the problem is that the productivity is not more required;

the realized technical effects are as follows: 1. the original integral base station is split into a split combination of a composite base station 2, a screw 3, a connecting base station 4 and a greenling bridge 5 through a split type unsealing structure, therefore, the greenling bridge 5 and the connecting base station 4 need to be customized individually, the required precision of the greenling bridge 5 is not high, the greenling bridge can be attached to gum, the composite base station 2, the screw 3 and the connecting base station 4 need higher precision and need to be processed by a numerical control machine, thus, the individually customized and precisely machined accessories can be separated for operation, the machining efficiency is greatly improved, each part of the completely split accessories can be manufactured in only ten minutes, the preparation time of the accessories is greatly reduced, the greenling bridge 5 can be customized to make about 20 sets of greenling planted teeth on the same plate surface at the same time, and twenty sets of complete greenling planted teeth can be made in 5 hours; 2. the accessory is split into simple parts, the manufacturing is easier, a 5-axis numerical control machine tool is not needed, only 4 axes are needed, the 4-axis machine tool can process simple parts in a few minutes, the screw 3 composite base station and the connection base station of the implant body 1 of the device can be manufactured in advance, the existing base station needs to be precisely processed inside and outside and at the front and back during processing, the interiors of two ends need to be processed, and the device is very complicated, so that the processing time is greatly prolonged; 3. the prior greenotal bridge dental implant cannot be mistaken when being assembled on a alveolar bone, once the errors occur, little errors occur in assembly, and finally when the greenotal bridge 5 is installed, the installation cannot be carried out, and the condition that the u installation hole 51 is not matched easily occurs, so the prior greenotal bridge dental implant either has the condition of non-lamination or frequent rework, the device cannot have the condition that the angle between the composite base station 2 and the connecting base station 4 can be finely adjusted by twice adhesion, and the connecting base station 4 and the installation hole 51 can also be slightly adjusted by adhesion, so the fault tolerance of the device is higher, the rework condition rarely occurs, the reworking is calculated, only one part needs to be reworked, the speed is high, no long-time waiting is needed, and the device can be debugged when being installed by the method, and is not suitable or abnormal in wearing, the greenling bridge frame of the device is 3D printed, reworking or grinding can be conveniently operated, the installation mode of the device is easier to operate, and the prior finish machining greenling bridge does not allow such operation, so that the original accuracy of the greenling bridge can be influenced, the assembly is more difficult, the problem of the assembly mode of the device is that unfit parts can be ground, and even if one part is processed immediately, a simple part can be processed only in ten minutes; 4. the processing mode is efficient like this, and the productivity is high, has reduced the threshold of greenling dental implant, and the time that the disease waited for has shortened greatly, probably waited for several days or ten days before, can accomplish on the same day now, and user experience is good, and the gum with be difficult to inflame has played the promotion effect to whole trade.

for better understanding of the above technical solutions, the following detailed descriptions will be provided in conjunction with the drawings and the detailed description of the embodiments.

When the invention is manufactured, the implant 1, the composite base station 2 which is installed in a matched manner, the screw 3 and the connecting base station 4 are completely processed and finished through a numerical control machine tool, the locking screw 22 and the locking hole 11 can be tightly matched and locked, the lower inverted cone outer wall of the composite base station 2 can be tightly attached to the inner wall of the locking hole 11, the horizontal bulge of the screw cap with the outer pentagon, outer hexagon or outer octagon is arranged outside the composite base station 2 and is vertical to the vertical axis of the composite base station 2, the shape of the horizontal bulge is similar to that of a prismoid, the prismoid is matched with the locking hole 11 of the implant 1, and a matched prismoid-shaped groove is arranged in the locking hole 11, so that the implant 1 and the composite base station 2 can only move up and down along the axis after being spliced and can not rotate, and can not rotate or separate after being locked by the locking screw 22; the outside of planting body 1 needs to have anti-skidding screw thread, the top of compound base station 2 docks boss 21 surface is smooth, closely laminate with the hollow bottom that links up base station 4 completely, the top of butt joint boss 21 will be near with locking snap ring 41 bottom, it is not too many also not few, just in time paste tightly, and the cavity of the locking snap ring 41 top of linking up the 4 inner chambers of base station as long as enable screw head 31 pass through can, and the round hole of locking snap ring 41 will block the laminating completely with screw head 31, locking snap ring 41 two sides all are smooth mirror surface, the bottom of screw head 31 also mirror surface, the outside and the mounting hole 51 shape laminating that link up base station 4 can.

When the invention is installed, firstly, a hole is drilled in a alveolar bone of a patient, the hole distance is based on actually measured data, then the parameter is input into a 3D printer, the size of an installation hole 51 needs to be based on the hole distance of the drilled hole in the alveolar bone, a titanium metal or zirconium oxide material is needed to be used for 3D printing of the greenotal bridge 5, the precision of 3D printing is not high as that of a numerical control machine, and can reach 0.2mm, an implant 1 is installed in the drilled hole of the alveolar bone, generally speaking, the greenotal bridge 5 needs to be manufactured by 4 conjoined teeth, can bear larger biting force and can reach higher strength, a locking screw 22 of a composite abutment 2 is screwed into a locking hole 11 of the implant 1, then the abutment 4 is covered and jointed on the top of the composite abutment 2, the lower cavity of the abutment 4 is ensured to be matched with a butt-joint boss 21 tightly without protruding, and then a screw 3 is locked in from an opening above the abutment 4, the screw is locked into the connecting hole 23, the screw head 31 is tightly pressed on the top of the locking snap ring 41, the base below the screw is installed, finally the mounting hole 51 of the greenling bridge 5 is aligned to each connecting base 4, and the sleeving is firmly performed to remove the adhesion, so that the installation is completed, because the matching base 2 and the connecting base 4 of the device are separated, the connecting base 4 can be customized according to the size of the mounting hole 51, the cutting difficulty is low, the device can be produced in advance, because the size of the mounting hole 51 is basically fixed, the composite base 2 can be processed in advance, the thread processing difficulty is low, only the matching surface of the butt joint boss 21 needs to be precisely processed, the processing difficulty is greatly reduced, the processing requirement of the locking snap ring 41 is precise, the processing difficulty of the original base is greatly reduced, the processed parts are simplified, and the processed parts of the device can be finely adjusted, the effect is better, and the installation is easier.

The sizes of each implant 1, the composite abutment 2, the connecting abutment 4 and the mounting hole 51 have standard size parameters, the implants can be prefabricated in advance, titanium metal or zirconia materials are needed, and the manufactured integral structure with the error not exceeding 0.01mm can be more matched with the skeleton of a human body.

The operation of implanting the implant 1 into the alveolar bone belongs to the conventional operation of dentistry, namely, the implant 1 is screwed and locked on a hole which is punched in advance in the alveolar bone, the bone can slowly heal the thread part of the implant 1 after about 3 months, and the implant 1 and the thread part are grown into a whole, so that the structure is firmer.

Although specific embodiments of the invention have been described above, it will be understood by those skilled in the art that the specific embodiments described are illustrative only and are not limiting upon the scope of the invention, and that equivalent modifications and variations can be made by those skilled in the art without departing from the spirit of the invention, which is to be limited only by the appended claims.
