Definitions
- the invention relates to a dental implant according to the preamble of patent claim 1.
- Dental implants of the aforementioned type are known in practice and comprise a receiving body which is inserted into the jawbone of a patient and grows there.
- a blind hole-like recess is formed, into which a shaft can be screwed, which serves as a support for a tooth tip, on which a cutting edge or a chewing surface of the dental implant is formed.
- the shaft may have on its front side facing away from the tooth head a capsule for receiving a sealant or adhesive, which is destroyed when screwing the shaft into the receiving body, so that the sealant or adhesive in the blind hole-like recess of the receiving body and distributed to the upper Edge rises to connect with the gums.
- the invention has for its object to provide a dental implant of the aforementioned type, at a controlled application of a flowable substance from the cavity of the shaft is possible.
- the shaft is thus connected to a discharge device for the flowable material, the actuation of which occurs during insertion of the shaft into the recess of the receiving body, so that the flowable material is distributed in the recess of the receiving body. Since the shaft simultaneously displaces the flowable material by insertion into the recess of the receiving body, it can flow to the edge of the blind hole-like recess and thus to the mouth of the facing end side of the dental implant, so that the flowable material with the dental implant limiting gum to seal of the dental implant construction.
- the flowable material is a sealant or adhesive which is associated with the subject's gums upon insertion of the dental implant and may be a dual cement or the like.
- the discharge device comprises a cylindrical or pot-like insert, which is displaceably guided in an end-face blind hole-like recess of the shaft, which forms the cavity for receiving the flowable substance, and which has at least one transverse opening on the circumference, which is in communication with the cavity of the shaft facing away from the end face of the insert.
- the cyclic -cylindrical insert which can be designed as a unilaterally closed inner sleeve, offset from the shaft so that the transverse opening is in fluid communication with the lumen of the shaft.
- the flowable material can be promoted from the shaft into the blind hole-like recess of the receiving body.
- the displacement of the insert relative to the shaft is preferably carried out by the advancing movement of the shaft when inserted into the receiving body, that is, the insert is then at least partially at the bottom of the blind hole-like recess of the receiving body, so that the axial pressure exerted on the shaft offset the insert relative to the shaft result.
- the insert is arranged in a transport position in an extended position relative to the shaft, in which the transverse opening is arranged on the side of a sealing lip facing away from the recess of the shaft, and arranged in an insertion position relative to the shaft in an activation position , in which the transverse opening is arranged on the side of the sealing lip facing the recess of the shank.
- the transport position can be secured by means of a securing device, which is before the onset of Shank is dissolved in the receiving body.
- the securing device is for example a plastic strip, which is arranged or clamped in the extended transport position between the shaft and the insert or the inner sleeve and can be removed by means of a tear tab, so that the insert or the inner sleeve are pressed into the cavity of the shaft can.
- the arranged on the peripheral wall of the inner sleeve or the insert opening passes over when inserting the shaft into the receiving body, the sealing lip at least partially, so that the substance from the cavity flow through the opening to the outside and can be distributed there.
- the inner sleeve acts like a displacement piston.
- the shaft has, in a preferred embodiment, an external thread which engages in an internal thread of the receiving body.
- the shaft may have at least one axial groove on its peripheral surface, over which the substance applied out of the cavity can advantageously be distributed in the receptacle of the receiving body and can penetrate to the edge of the blind-hole-like recess.
- the receiving body is a component that is inserted into the jaw of a person and grows there. But it is also conceivable that the receiving body is formed by the jaw itself. In this case, the shaft is thus inserted or screwed directly into the jaw.
- the cavity, which is formed in the shaft for receiving the flowable material, for example, has a receiving volume of 4 to 7 mm 3 , that is, flowable substance of this amount can be kept in the shaft.
- FIG. 1 shows a dental implant inserted into a jaw bone with a shaft before the discharge of a sealant
- Fig. 2 is a Fig. 1 corresponding view, but after the discharge of the sealant and the placement of a tooth head.
- a dental implant 10 which has a receiving body 12 which is inserted into a corresponding, orthodontically prepared recess 14 of a jawbone 16 of a person and grown there.
- the receiving body 12 has on its side facing the oral cavity a blind hole-like recess 18 which is provided with an internal thread 20.
- the blind hole-like recess 18 serves to receive a shank 22, which is designed like a bolt and serves as a support for a tooth head 24, on which a purchase
- a shank 22 which is designed like a bolt and serves as a support for a tooth head 24, on which a purchase
- an external thread 26 is formed, which engages in the internal thread 20 of the recess 18 of the receiving body 12.
- the receiving body 12 thus forms a socket for the shaft or bolt 22nd
- the shaft 22 has a blind-hole-like receiving space 28 forming a cavity for a flowable substance, which may be formed as a sealant and / or adhesive.
- a cup-like insert 30 is displaceably guided, which forms a closed on one side inner sleeve, which is provided on its peripheral wall with at least one transverse opening 32 which is in fluid communication with the interior of the cup-like insert 30 with its surroundings.
- the pot-like insert 30 is guided on an annular sealing lip 34 of the shank 22 forming an outer sleeve, so that, depending on the position of the transverse opening 32, the cavity or receiving space 28 of the shank 22 is in fluid communication with the surroundings of the shank or not.
- the application of the dental implant 10 shown in the drawing takes place in the manner described below.
- the receiving body 12 is inserted into a corresponding recess of the jaw bone 16 so that it grows there.
- the shaft 22 can be inserted and screwed into the recess 18 of the receiving body 12 together with the insert 30, which is located in the transport position shown in FIG. 1.
- the insert 30 then abuts with its free end face on the bottom of the recess 18.
- the insert 30 experiences by the pressure exerted on its end face an offset relative to the shaft 22 so that it is inserted into the cavity 28 of the shaft 22 and there in the manner of a displacement piston therein absorbed flowable substance displaced.
- the transverse openings 32 pass over the sealing lip 34 so that the receiving space 28 is in flow or flow communication with the surroundings of the shaft 22.
- the flowable substance initially received by the receiving space 28 is thus conveyed to the outside of the shaft 22, where it is distributed and rises up to a gum 36 and connects with this.
- the flowable material thus acts as a sealant and adhesive.
- the shaft 22 has at least one axially aligned groove 38 on its circumference.
