Background technology

Since nineteen sixty-five doctor branemark invention artificial dental root of the tooth, push dental treatment to new epoch, implant tooth implants in alveolar bone by one by artificial tooth root, to replace the artificial tooth of one whole dermal tooth, make the situation having identical dermal tooth when chewing, it has and bears that gmatjpdumamics is high, foreign sense, and do not injure the advantages such as natural health tooth, replace the selection of the common people for facing or movable artificial tooth gradually, thousands upon thousands agomphosis patient is received benefits, and therefore quality of life also promotes.

Commonly using in implanted treatment, dentist is when the operation of dental drill hole is planted in execution, can according to preoperative computed tomography (Computed tomography, be called for short CT) carry out tooth implantation planning, the position that parameter collected when utilizing scanogram implement three-dimensional model determines to plant tooth according to desirable, angle and the degree of depth, and then correspondingly produce one and plant tooth accessory.

Although, computed tomography can provide an effective Surgery Simulation environment, such as demonstrate the accurate location of teeth groove skeleton height, thickness and neural blood vessel distribution, different visual angles can also be switched to inspect implant setting position, but tradition is planted tooth accessory and is mainly located through latch rod, and be limited to the external form of latch rod, cause cannot precisely indicating actual relative position, cause the mistake in parameter interpretation, and then produce a guide plate defective, after making dentist take this guide plate, cannot according to patient's mouth, practical situation be done to revise further again.

Therefore, the bore position that preoperative evaluation flaw causes, the degree of depth, angular deviation and dislocation, will make artificial tooth root cannot install on the position of prior programming, and then cause meaningless complication or medical tangle etc.; In addition, even if guide plate carries out lock when establishing, because this guide plate normally makes with plastic material, therefore when artificial tooth root is implanted in alveolar bone through this guide plate, if dentist is affectedly bashful improper, this artificial tooth root will be made will to be directly expressed to this guide plate, when this guide plate does not support again backstop effect, to the implantation depth of this artificial tooth root be caused excessively dark, and injure the situation of nerve or nasal cavity etc., real palpus improves.

Utility model content

Therefore, the purpose of this utility model, be provide a kind of can precise positioning plant tooth accessory, it can reach precise positioning, easy to use outside, more effectively can control implantation depth, improve and plant tooth stability and success rate.

So, this utility model can precise positioning plant tooth accessory, it includes a body, and one is located at the guidance part on this body, and one connects this guidance part and the sleeved part of the coated human body dental tissue that can coincide; Wherein, this sleeved part is soft materials; Separately, this guidance part includes a guide hole, and one to be sheathed on this guide hole and baffle ring in rigid material.This dental tissue refers to gingiva, tooth.

Be with, when an artificial tooth root implantation is carried out planting tooth, when making sleeved part be coated on this human body dental tissue, and then reach easily fixing and easy to use outside, this baffle ring design simultaneously, the implantation depth of artificial tooth root more can be avoided excessively dark, and injure the situation of nerve or nasal cavity etc., and then tooth stability and success rate are planted in raising.
