Background technology
Oral cavity activity artificial tooth magnetic retention body technique is to utilize magnetic principles at the abutment residual root, Center stake core, armature keeper to be set, on the base plate of detachable dental prostheses, Magnetitum is set, armature and Magnetitum are attracted each other, thereby realize detachable dental prostheses fixing in the oral cavity.Detachable dental prostheses magnetic retention body technique need not use metal clasp, have advantages of avoid snap ring to the damage of abutment, pluck wear simple to operate, easy to clean, the oral cavity is attractive in appearance, use in Oral Repair.But the shortcoming of detachable dental prostheses magnetic retention technology is: stick with glue the Center stake core that is connected in gingiva and easily come off, when Center stake core came off, its detachable dental prostheses retention is poor maybe can't be fixed.
Telescope crown is also current stomatologic new technique, is comprised of interior hat and outer hat, and interior hat is bonded on abutment, labels in outer hat is enclosed within, and outer hat and the chimeric formation retention of interior hat driving fit are for detachable dental prostheses provides the maintenance effect.But the shortcoming of telescope crown is: use long afterwards, interior hat is easily bonding not firm and come off; Telescope crown abutment neck section frangibility changes magnetic attachment reparation etc. again into after fractureing, magnetic attachment Center stake core easily comes off, and need repeatedly be adhesively fixed, and has a strong impact on repairing effect.Detachable dental prostheses magnetic attachment and telescope crown be the application in the single jaw tooth of Oral Repair simultaneously, and above-mentioned shortcoming also can occur, and makes the patient repeatedly repair and firm detachable dental prostheses.Bring inconvenience to patient's life, strengthened patient's misery, increased medical expense.Therefore invent and a kind ofly both the Center stake core of magnetic attachment can be fixedly secured, the interior hat of telescope crown can be fixedly secured again, the technology of abutment neck section difficult drop-off, make magnetic attachment detachable dental prostheses and telescope crown long service life, reduce the patient suffering, the telescope crown magnetic attachment conjoined device that reduces medical expense is very necessary.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly both the Center stake core in the magnetic retention body technique can be fixedly secured, the interior hat of telescope crown can be fixedly secured again, the technology of abutment neck section difficult drop-off, magnetic attachment detachable dental prostheses and telescope crown are repaired to be extended service life, reduce the patient suffering, reduce the telescope crown magnetic attachment conjoined device of medical expense.
This utility model is achieved in that
Telescope crown magnetic attachment conjoined device, formed by detachable dental prostheses, Magnetitum, armature, Center stake core, select without obviously loosening one or several residual roots, through after root canal, make one or several Center stake cores, Center stake core is placed in residual root, the top of Center stake core is connected with connecting rod, the other end of connecting rod is connected with the interior hat of telescope crown, and the outside of interior hat is provided with outer hat, and abutment is placed in interior hat.
Through after root canal, carry out tooth preparation without obviously loosening abutment, telescope crown is comprised of interior hat and outer hat, and telescope crown can be 1, and perhaps several are connected side by side.
The outer hat of telescope crown is placed in the position corresponding with interior hat, plays packing interaction.
Magnetitum is located in detachable dental prostheses; The top of Center stake core is provided with armature, and armature and Magnetitum attract each other, and detachable dental prostheses is fixed.
Main points of the present utility model are: use connecting rod all to couple together being preced with in one of magnetic attachment or several Center stake core and telescope crown one or several, form telescope crown magnetic attachment conjoined device, both made and the Center stake core in the magnetic retention body technique can be fixedly secured, the interior hat of telescope crown can be fixedly secured again, realize that magnetic attachment detachable dental prostheses and telescope crown extend service life, reduce the patient suffering, reduce the purpose of medical expense.
One end of this utility model telescope crown magnetic attachment conjoined device connecting rod is connected with the top of Center stake core, and armature is cast in Center stake core top; Answer the position to establish Magnetitum at detachable dental prostheses Center stake nuclear phase; Magnetitum connects detachable dental prostheses.The other end of connecting rod is connected with interior hat, and the Center stake nuclear phase at the interior hat of telescope crown and front portion or rear portion is connected, and establishes outside telescope crown at the interior side of labeling corresponding site and is preced with.
Center stake core described in the utility model refers to will metal material imbed after casting the stake in root of the tooth; Described armature keeper refers to be arranged on Center stake core top, is used for the device of attracting each other with the Magnetitum that is arranged on the base plate.Described Magnetitum is a kind of magnetic material; Magnetitum is fixed on the bottom of detachable dental prostheses base plate, and is corresponding with the armature keeper position, attracts each other.Metal link rod described in the utility model, Center stake core, interior hat, outer hat, metal support panel material are that billon, titanium alloy, blunt titanium, nichrome, cochrome a kind of material is wherein made.
In this utility model, the manufacture method of each parts, connected mode are existing disclosed prior art.
This utility model is according to patient's oral condition, one or several residual roots can be put Center stake core, and one or several abutments are put the semifixed detachable dental prostheses that in telescope crown, hat forms and put together.
This utility model combines telescope crown and two kinds of technology of magnetic attachment by connecting rod at world's oral medical field first, has obtained that telescope crown and magnetic attachment are both fixedly secured, the beat all technique effect of detachable dental prostheses and telescope crown life; Make hat difficult drop-off in magnetic attachment Center stake core and telescope crown, abutment is the effect of frangibility not, has greatly reduced patient's misery and medical expense.The utlity model has creativeness, novelty and practicality.
