Description

A kind of two-period form dentistry implant

Technical field

The present invention relates to tooth implantation technology field, in particular to a kind of two-period form dentistry implant.

Background technique

Plantation recovery technique has become the optimal treatment method of most of agomphosis patients at present.It can be very after planting body implantationRestore the oral cavity function of patient well, protect the stabilization and health of oral cavity hard and soft tissue, and reaches good aesthetic effect.ButIt is that the success rate after plantation is repaired is significantly lower than planting body survival rate, or even is up to two using the failure rate of quick dental implant methodAt reason is that a plurality of types of complication can be generated after planting reparation, such as bacterium infection causes gingival infection.And this occursClass situation has the long disadvantage of slow effect, the course for the treatment of by topical administration and drug for oral administration, it is difficult to long-term after guaranteeing implantationIt uses.

Summary of the invention

The present invention provides a kind of two-period form dentistry implant, is gone directly the logical of gum bone by being equipped in implant for medical fluidRoad, the patient after helping to carry out plantation prosthesis carry out sterilization medical fluid or promote the benefit of medical fluid of the bone in conjunction with implantIt fills.

A kind of two-period form dentistry implant, including implant, base station, center screw and sealing ring, be equipped in the implant withThe compatible blind hole of center screw, the implant are fixedly connected with base station by center screw, the sealing ring be located at implant withBetween base station, the implant includes countersunk head connected unit and medicine liquid channel, and the sealing ring is abutted with countersunk head connected unit, the medical fluidChannel has inlet and outflux, and the inlet is located at countersunk head connected unit, and the outflux is located at the outer wall of implant.

Medicine liquid channel of the present invention includes a main channel and several bypass passages, the top of each bypass passageIt is connected to main channel, the top of the main channel is connect with inlet, and the end of the bypass passage is connect with outflux.InstituteStating main channel includes straightway and spiral section, and the main channel is connect by straightway with inlet, and the spiral section is around blindHole arrangement.The medicine liquid channel has two groups, and the spiral section of two main channels is symmetrical with blind hole setting, is distributed in double helix.

Inlet of the present invention has chamfering.

Countersunk head connected unit of the present invention and sealing ring contact position are conical surface.

The stopple of protrusion, the stopple and inlet are equipped at sealing ring of the present invention and the contact surface of countersunk head connected unitIt is adapted.

Two-period form dentistry implant disclosed by the invention, implant have additional inlet, medicine liquid channel and outflux, can be withMedicine liquid channel flow direction and outflux position are designed according to patient's gum bone feature, so that being in for the design of patient's Yi Fasheng lesionExisting greater density distribution.After patient completes plantation reparation, medicine liquid channel injection can be killed by unloading base station and sealing ringBacterium medical fluid promotes medical fluid of the bone in conjunction with implant, reduces gum infection of bone and raising bone and implant combination degree to reachPurpose.

Specific embodiment

It is carried out below with reference to technical effect of the embodiment and attached drawing to design of the invention, specific structure and generation clearChu is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hairBright a part of the embodiment, rather than whole embodiments, based on the embodiment of the present invention, those skilled in the art are not being paidOther embodiments obtained, belong to the scope of protection of the invention under the premise of creative work.In addition, be previously mentioned in textAll connection/connection relationships not singly refer to that component directly connects, and referring to can be added deduct according to specific implementation situation by addingFew couple auxiliary, to form more preferably coupling structure.Each technical characteristic in the invention, in not conflicting conflictUnder the premise of can be with combination of interactions.

As shown in figures 1-4, a kind of two-period form dentistry implant, including implant 1, base station, center screw and sealing ring 3, instituteIt states and is equipped with blind hole 2 compatible with center screw in implant 1, the implant 1 is fixedly connected with base station by center screw, describedFor sealing ring 3 between implant 1 and base station, the implant 1 includes countersunk head connected unit 4 and medicine liquid channel, the sealing ring 3 withCountersunk head connected unit 4 abuts, and the medicine liquid channel has inlet 5 and outflux 6, and the inlet 5 is located at countersunk head connected unit 4On, the outflux 6 is located at the outer wall of implant 1.The implant 1 is based on SLM technology and is made, can root during three dimensional designPersonalized medicine liquid channel is designed according to the difference of different patient's gum bones, so that medical fluid can be smoothly after the injection of inlet 5Arrival needs at application.Sealing ring 3 is added between implant 1 and base station simultaneously, and tooth-implanting is avoided to have food in normal useOther bacteriums invade medicine liquid channel in residue or oral cavity.

As further preferred embodiment, the medicine liquid channel includes a main channel 7 and several bypass passages8, the top of each bypass passage 8 is connected to main channel 7, and the top of the main channel 7 is connect with inlet 5, the branchThe end of paths 8 is connect with outflux 6.The pipe diameter of main channel 7 and bypass passage 8 has apparent difference, this is becauseMedical fluid is injected from inlet 5, so main channel 7 will have sufficiently large volume to be just avoided that liquid medicine spill, but medical fluid is logical from branchRoad 8, which is flow to, needs outflux 6 then can not be too fast, gathers infiltration affected part to prevent medical fluid.

As further preferred embodiment, the main channel 7 includes straightway and spiral section, and the main channel 7 is logicalIt crosses straightway to connect with inlet 5, the spiral section is arranged around blind hole 2.Spiral section can lead to 1 plurality of positions of implant, haveHelp the design of bypass passage 8.

As further preferred embodiment, the medicine liquid channel has two groups, and the spiral section of two main channels 7 is symmetricalIt is arranged in blind hole 2, is distributed in double helix.

As further preferred embodiment, the inlet 5 has chamfering.The chamfering that inlet 5 is equipped with taper hasConducive to the injection of medical fluid.

As further preferred embodiment, the countersunk head connected unit 4 and 3 contact position of sealing ring are conical surface, are hadConducive to sealing.

As further preferred embodiment, protrusion is equipped at the sealing ring 3 and the contact surface of countersunk head connected unit 4Stopple 9, the stopple 9 are adapted with inlet 5.

Better embodiment of the invention is illustrated above, but the invention is not limited to the implementationExample, those skilled in the art can also make various equivalent modifications on the premise of without prejudice to spirit of the invention or replaceIt changes, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
