Description

Technical Field

[0001] The utility model relates to the technical field of dental implants, in particular to a dental implant restoration device without a base and an integrated crown. Background Art

[0002] Denture implant, also known as artificial tooth implant, is the process of implanting an implant as a tooth root in the jawbone in the edentulous area of ​​the mouth, and then burying a covering screw. After the implant is combined with the jawbone, the covering screw is removed, and then a healing abutment is placed on the upper end of the implant. After the cuff is healed, the healing abutment is removed and a transfer rod is placed. After the mold is taken, the transfer rod is removed from the mouth, the healing abutment is put back into the mouth, and the impression is sent to the processing factory for denture production, thus forming a denture suitable for the edentulous area of ​​the mouth.

[0003] Denture implants can significantly improve patients' chewing ability and feel comfortable, similar to real teeth, making them the most advanced and popular dental implant technology today. However, currently, after the doctor completes the dental implant surgery, the doctor will lock the cover screw into the upper part of the implant, wait for healing to be completed, cut the gums open, remove the original cover screws, and then lock the healing base, suture the gums, and wait for the gums to heal and shape before repairing. Traditional dental implants require repeated replacement of implant accessories, which prolongs the treatment time, and bacteria are easily introduced during the insertion and removal process, leading to implant failure.

[0057] In order to better illustrate the technical effect of the present invention, the present invention provides the following specific embodiments to illustrate the above technical process:

[0058] Embodiment 1: A dental implant repair device with an integrated crown without an abutment. After the doctor completes the dental implant surgery, the repair device is a special accessory (i.e., MU connecting component 2) that is directly locked according to the bone / gum height without locking in a healing abutment or covering screws. The repair can be performed directly after the wound is healed, without the need to open the gums a second time to replace accessories and wait for healing. MU is suitable for most implant brands and models on the market.

[0059] The MU connection assembly 2 comprises an MU screw portion 21, an MU truncated cone portion 22 and an MU raised portion 23 which are sequentially connected from bottom to top, and has the following characteristics:

[0060] Gold or pink finish;

[0061] The MU connection component 2 has a small diameter;

[0062] After the MU connection component 2 is locked in, it does not need to be removed.

[0063] Before using the MU connection component 2 , the doctor needs to implant the implant 1 into the patient's mouth.

[0064] The utility model is a repair method without a base, which simplifies the operator's work process, such as Figure 3 As shown, the specific steps include the following:

[0065] When the doctor implants the implant 1 into the gum bone according to the clinical condition, the upper part of the implant 1 is locked into the MU connection component 2; the MU frustum 22 of the MU connection component 2 can play a role similar to a healing abutment or a covering screw;

[0066] Use the intraoral scanning equipment on the market to obtain intraoral data, use computer-aided design software to carry out restoration design and computer-aided production software to carry out production work, grind or print the designed restoration shape with dental materials, and obtain the restoration crown 3;

[0067] Install the restoration crown 3 onto the upper part of the MU connection component 2.

[0068] Traditional restoration requires designing and manufacturing a crown based on the abutment. Compared with the restoration method without abutment, it has the following advantages:

[0069] The utility model optimizes the process, eliminating the need for repeated operations of covering screws and healing abutments, and at the same time eliminating the need for abutments, thereby reducing the thickness of the abutments, leaving more space for restoring the crown 3;

[0070] Clinicians need to perform repeated surgeries to replace the healing base, cover the screws, and wait for healing, but the present invention does not require this, thus reducing the number of surgical procedures.

[0071] Traditional restorations require the abutment to be fixed by glue, but the present invention does not require this.

[0072] When the clinician needs to change the restoration design, the utility model can directly replace the three parts of the restored crown that have been remade.

[0073] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
