Description

Technical Field

[0001] The present invention relates to the technical field of oral restoration, and in particular to a pre-bonded abutment template for upper implant restoration and a preparation method thereof. Background Art

[0002] Fixed restoration is one of the main methods of oral restoration; the last step of fixed restoration is to bond the restoration to the tooth tissue through adhesive. This step is also the most important step in fixed restoration. If there is a problem with the bonding between the restoration and the tooth tissue, all the previous work will be wasted.

[0003] Existing fixed restorations do not use pre-bonded abutment models in clinical practice. After the doctor has positioned the abutment in the patient's mouth, he or she directly wears the restoration on the abutment. After the excess adhesive overflows under the gums of the patient, the doctor needs to use tools to clean the excess adhesive out of the patient's mouth. When the patient's mouth opening is not enough, or the abutment shoulder penetrates deep into the gums, the doctor's cleaning work becomes very difficult, resulting in the excess adhesive in the patient's mouth being difficult to clean. Failure to clean the adhesive can cause a series of complications such as gingivitis and periodontitis, which seriously affect the patient's health. In addition, the doctor's wearing time is prolonged due to the need to clean the excess adhesive in the patient's mouth, thereby prolonging the patient's mouth opening time and increasing the patient's pain. Summary of the invention

[0004] In view of this, the object of the present invention is to provide an implant upper restoration pre-bonded abutment model and a preparation method thereof, which can convert the cleaning of excess adhesive from an intraoral operation to an extraoral operation through a simulated abutment, reduce the doctor's wearing time, and reduce the patient's mouth opening time and pain.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a pre-bonded abutment prototype for implant upper restoration, including a hollowed-out implant upper restoration, and also including a pre-bonded abutment prototype inserted in the implant upper restoration; the pre-bonded abutment prototype includes a steel nail, and a resin abutment prototype solidified and formed at one end of the steel nail facing the implant upper restoration; the end of the steel nail to which the resin abutment prototype is bonded and fixed is the fixed end, and the end of the steel nail away from the resin abutment prototype is the clamping end, and a mark is provided on one side of the clamping end; the resin abutment prototype includes an embedded portion inserted into the implant upper restoration, and a closed portion located outside the implant upper restoration and in contact with the outer surface of the implant upper restoration.

[0006] Preferably, the radius of the steel nail gradually decreases along the direction from the fixing end to the clamping end.

[0007] Preferably, a bonding cavity is provided inside the implant upper restoration, the bonding cavity is opened at one end facing the steel nail, and the embedded portion is located inside the bonding cavity.

[0008] Preferably, an adhesive layer is filled between the inner wall of the bonding cavity and the embedded portion.

[0009] Preferably, the shape of the embedded portion changes with the shape of the bonding cavity.

[0010] Preferably, the adhesive layer is a dental cement adhesive layer.

[0011] A method for preparing a pre-bonded abutment template for implant upper restoration, comprising the following steps:

[0012] (1) Inspecting the implant upper restoration;

[0013] (2) After the implant upper restoration is inspected and qualified, vaseline is dipped into a brush and evenly applied to the inner cavity of the implant upper restoration by the brush. The thickness of the vaseline in the inner cavity of the implant upper restoration is based on the thickness required by the adhesive;

[0014] (3) After applying vaseline inside the implant upper restoration, use another brush to dip in resin and fill it into the inner cavity of the implant upper restoration until the inner cavity of the implant upper restoration is filled, and then insert the fixed end of the steel nail into the resin;

[0015] (4) When the resin chemically reacts to cure and generate heat to a hardened state, the resin is solidified on the fixed end of the steel nail to form the resin base model, and the embedded part of the resin base model is inserted into the inner cavity of the implant upper restoration, and the closed part of the resin base model overflows to the outside of the implant upper restoration due to the steel nail being inserted into the inner cavity of the implant upper restoration.

[0016] ⑸ When the resin chemical reaction solidifies and generates heat to a hardened state, the resin base prototype is directly taken out from the inner cavity of the upper implant restoration through the clamping end of the steel nail. After taking it out, the resin base prototype is inserted into the inner cavity of the upper implant restoration through the steel nail. This insertion and removal is repeated multiple times to check the tightness, smoothness of positioning and tightness between the resin base prototype and the inner cavity of the upper implant restoration.

[0017] (6) When the tightness, smoothness of seating and tightness between the resin base mold and the upper implant restoration are checked and qualified, a mark is set on one side of the clamping end of the steel nail.

[0018] ⑺Finally, the pre-bonded abutment prototype is completely removed from the inner cavity of the implant upper restoration, and the resin abutment prototype is no longer inserted into the inner cavity of the implant upper restoration through the steel nail, and the vaseline in the inner cavity of the implant upper restoration is cleaned.

[0019] Preferably, the resin is a self-curing resin.

[0020] The technical effect of the present invention is mainly reflected in that the pre-bonded abutment mold can simulate the abutment inside the patient's mouth outside the patient's mouth, so that excess adhesive can be effectively cleaned outside the patient's mouth, thereby converting the cleaning of the adhesive from an intraoral operation to an extraoral operation, reducing the doctor's wearing time, reducing the patient's mouth opening time and pain, and also avoiding a series of complications such as inflammation and fever in the patient's mouth due to unclean handling of the adhesive, thereby protecting the patient's health.

[0024] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0025] In this embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right", "left end", "above", "back", "middle", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] In addition, in this specific embodiment, if the connection or fixing method between components is not specifically described, the connection or fixing method can be through bolt fixing or pin fixing, or pin shaft connection and the like commonly used in the prior art, and therefore, it is not described in detail in this embodiment.

[0027] A pre-bonded abutment for implant restoration, such as Figure 1-3As shown, it includes a hollowed-out implant upper restoration 1, and also includes a pre-bonded abutment prototype 2 inserted into the implant upper restoration 1; the pre-bonded abutment prototype 2 includes a steel nail 21, and a resin abutment prototype 22 solidified and formed at one end of the steel nail 21 facing the implant upper restoration 1; the end of the steel nail 21 to which the resin abutment prototype 22 is bonded and fixed is a fixed end 211, and the end of the steel nail 21 away from the resin abutment prototype is a clamping end 212, and a mark 213 is provided on one side of the clamping end 212; the resin abutment prototype 22 includes an embedded portion 221 inserted into the implant upper restoration 1, and a closed portion 222 located outside the implant upper restoration 1 and in contact with the outer surface of the implant upper restoration 1.

[0028] The radius of the steel nail 21 gradually decreases from the fixed end 211 to the clamping end 212. The radius of the fixed end 211 is larger than the radius of the clamping end 212, and the contact area between the resin and the fixed end 211 is larger, which is conducive to the bonding and fixing of the resin base die 22 on the fixed end 211.

[0029] The upper implant restoration 1 is provided with a bonding cavity 11 inside. The bonding cavity 11 is opened at one end facing the steel nail 21 . The embedded portion 221 is located inside the bonding cavity 11 .

[0030] In this embodiment, an adhesive layer 12 is filled between the inner wall of the bonding cavity 11 and the embedded portion 221 .

[0031] In this embodiment, the shape of the embedding portion 221 changes with the shape of the bonding cavity 11 .

[0032] In this embodiment, the adhesive layer 12 is a dental cement adhesive layer.

[0033] In this embodiment, the resin base mold 22 is a self-curing resin base mold.

[0034] A method for preparing a pre-bonded abutment template for implant upper restoration, comprising the following steps:

[0035] (1) inspecting the implant upper restoration 1;

[0036] (2) After the implant upper restoration 1 is inspected and found to be qualified, (the implant upper restoration 1 with screw holes reserved needs to block the screw holes with paper towels first) use a brush to dip in vaseline, and evenly apply the vaseline on the inner cavity of the implant upper restoration 1 with the brush. The thickness of the vaseline in the inner cavity of the implant upper restoration 1 is based on the thickness required by the adhesive;

[0037] (3) After applying vaseline inside the implant upper restoration 1, use another brush to dip in resin to fill the inner cavity of the implant upper restoration 1, and fill the inner cavity of the implant upper restoration 1, and then insert the fixed end 211 of the steel nail 21 into the resin;

[0038] ⑷ When the resin chemically reacts to cure and generate heat until it becomes hard, the resin is solidified on the fixed end 211 of the steel nail 21 to form the resin base model 22. The embedded portion 221 of the resin base model 22 is inserted into the inner cavity of the implant upper restoration 1, and the closed portion 222 of the resin base model 22 overflows to the outside of the implant upper restoration 1 due to the steel nail 1 being inserted into the inner cavity of the implant upper restoration 1.

[0039] ⑸ When the resin chemical reaction solidifies and generates heat to a hardened state, the resin base mold 22 is directly taken out from the inner cavity of the implant upper restoration 1 through the clamping end 212 of the steel nail 21. After taking it out, the resin base mold 22 is inserted into the inner cavity of the implant upper restoration 1 through the steel nail 21. This insertion and removal is repeated many times to check the tightness, smoothness of positioning and tightness between the resin base mold 22 and the inner cavity of the implant upper restoration 1.

[0040] (6) After the tightness, smoothness of placement and tightness between the resin base model 22 and the implant upper restoration 1 are checked to be qualified, a mark 213 is marked on one side of the clamping end 212 of the steel nail 21. The mark 213 is used to mark the side as the labial and buccal side of the clamping end 212, which is conducive to the subsequent filling of the adhesive into the inner cavity of the implant upper restoration 1, and the adhesive is evenly applied to the inner wall of the implant upper restoration 1 through the pre-bonded base model 2, so as to avoid the adhesive failing to fill the thickness reserved by vaseline due to the wrong insertion of the pre-bonded base model 2, which affects the placement of the implant upper restoration 1 on the base in the patient's mouth.

[0041] ⑺Finally, the pre-bonded abutment mold 22 is completely removed from the inner cavity of the implant upper restoration 1, and the resin abutment mold 22 is no longer inserted into the inner cavity of the implant upper restoration 1 through the steel nail 21, and the vaseline in the inner cavity of the implant upper restoration 1 is cleaned.

[0042] In this embodiment, the resin is a self-curing resin.

[0043] Implant dentures include three indispensable components: implant pins implanted in the upper and lower jaws (commonly known as implants), abutments connecting the implants and restorations, and restorations (porcelain teeth or all-ceramic teeth, which are used to restore the patient's occlusal function and are also the upper structure of the implant). The industry stipulates that one denture is one unit. In this embodiment, the implant upper restoration 1 is a three-unit restoration.

[0044] The method for using the pre-bonded abutment template for implant upper restoration is as follows: after the pre-bonded abutment template 2 is completed, when the doctor needs to bond and fix the implant upper restoration to the abutment in the patient's mouth, he only needs to fill the adhesive into the inside of the bonding cavity 11 of the implant upper restoration 1 outside the mouth, and then confirm which side of the pre-bonded abutment template 2 is the lip and cheek side according to the mark 213 on the steel nail 21, and then repeatedly insert the pre-bonded abutment template 2 into the bonding cavity 11 of the implant upper restoration 1, because the thickness of the bonding cavity 11 of the implant upper restoration 1 is reserved by vaseline before, so the embedded part 221 of the pre-bonded abutment template 2 and the inner part of the bonding cavity 11 are in good contact with each other. There is a gap between the walls. After the pre-bonded abutment prototype 2 is repeatedly inserted into the bonding cavity 11 of the implant upper restoration 1, the adhesive will fill the gap to form an adhesive layer 12. Therefore, the thickness of the adhesive layer 12 is the thickness of the gap between the embedded part 221 and the inner wall of the bonding cavity 11. During the repeated insertion and removal of the pre-bonded abutment prototype 2, excess adhesive will overflow. When the tightness, smoothness of positioning and tightness between the resin abutment prototype 22 and the implant upper restoration 1 are qualified, use a paper towel to clean the adhesive traces on the outside of the implant upper restoration 1. Finally, the doctor can bond and fix the implant upper restoration 1 to the abutment in the patient's mouth.

[0045] The technical effect of the present invention is mainly reflected in that the pre-bonded abutment mold can simulate the abutment inside the patient's mouth outside the patient's mouth, so that excess adhesive can be effectively cleaned outside the patient's mouth, thereby converting the cleaning of the adhesive from an intraoral operation to an extraoral operation, reducing the doctor's wearing time, reducing the patient's mouth opening time and pain, and also avoiding a series of complications such as inflammation and fever in the patient's mouth due to unclean handling of the adhesive, thereby protecting the patient's health.

[0046] Of course, the above are only typical examples of the present invention. In addition, there may be many other specific implementations of the present invention. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
