Description

A three-in-one implant restoration abutment for oral implantation and method thereof

Technical Field

The present invention belongs to the technical field of oral treatment and restoration, and in particular, relates to a three-in-one implant restoration base for oral implantation and a method thereof.

Background Art

Dental implants are surgically placed into the alveolar bone of the edentulous area. After several months, when the implant is tightly integrated with the alveolar bone, a restorative abutment and crown are installed on the implant. The abutment and crown can be divided into temporary use and formal long-term use. Before installing the formal abutment and crown, a temporary abutment and crown need to be installed as a transition.

After the existing implant is implanted into the alveolar bone, a healing cap, a scanning rod, a temporary restoration abutment, and a permanent restoration abutment are required. This method requires multiple disassembly and assembly of the temporary abutment, scanning rod and other components on the implant. The operation is cumbersome and can easily destroy the stability of the implant. In addition, the dental clinic needs to be equipped with more parts, which increases the number of surgical steps and the treatment time for the patient.

Summary of the invention

The technical problem to be solved by the present invention is to provide a three-in-one implant restoration abutment for oral implants and a method thereof. The restoration abutment has the functions of a healing cap, a scanning rod, a temporary restoration abutment, and a permanent restoration abutment, and can be placed after the alveolar bone has healed. The restoration abutment does not need to be moved or removed again during the entire restoration process, which facilitates the restoration work, reduces costs, reduces the probability of misuse of accessories, and can minimize the patient's discomfort and infection risk during the restoration process, thereby shortening the treatment time.

In order to solve the above technical problems, the present invention provides the following technical solutions:

A three-in-one implant restoration base for oral implantation, comprising: a healing cap for connecting a tooth crown and a lower connecting base for connecting an implant, the healing cap and the lower connecting base are fixedly connected via a connecting section, a marking surface for scanning alignment is provided on the outer side of the top of the healing cap, and a limiting portion is fixedly connected to the outer surface of the connecting section;

A step hole is coaxially opened in the middle of the healing cap, the connecting section and the lower connecting base. The upper end of the step hole passes through the upper end surface of the healing cap, and the lower end of the step hole passes through the lower end surface of the lower connecting base. A positioning screw is arranged in the step hole.

The following is a further optimization of the above technical solution by the present invention:

The outer surface diameters of the healing cap and the lower connecting base are smaller than the outer surface diameter of the connecting section, and the outer surface of the limiting portion is a conical surface structure.

Further optimization: the number of the marking surfaces is two, the two marking surfaces are symmetrically arranged at the two sides of the healing cap, the marking surfaces are inclined surfaces, and the marking surfaces gradually tilt toward the sides of the healing cap from top to bottom.

Further optimization: the limiting portion includes an inclined surface connected to the connecting section, and a first groove and a second groove are sequentially arranged on the inclined surface near the connection of the healing cap, and the size of the first groove is larger than that of the second groove.

Further optimization: the step hole includes a first step groove, a second step groove and a third step groove which are sequentially connected from top to bottom, and the inner bottom wall of the third step groove is provided with a through hole which penetrates the lower end surface of the lower connecting base.

Further optimization: the second step groove is a tapered hole, the large end of the second step groove is connected to the first step groove, the small end of the second step groove is connected to the third step groove, and the inner surface diameter at the lower end of the second step groove matches the inner surface diameter of the third step groove.

Further optimization: the healing cap, the lower connecting base and the connecting section are integrally formed, and are made of titanium alloy material. A plurality of limiting surfaces are provided on the outer surface of the bottom end of the lower connecting base, and the limiting surfaces are planar structures.

The present invention also provides a method for using a three-in-one implant restoration abutment for oral implantation, based on the above-mentioned three-in-one implant restoration abutment for oral implantation, comprising the following steps:

Step 1: The clinician transmits the CBCT data to the processing software, which recognizes and edits the 3D model. Then, the 3D model size data is imported into the 3D printer, and the restoration abutment and crown are printed to obtain the restoration abutment blank and crown.

Step 2: Machining the printed restoration abutment blank and deburring the crown to make the surface of the restoration abutment blank and the crown smooth and meet the use requirements;

Step 3: Install the implant on the gum between two adjacent teeth in the oral gums, then insert the lower connecting base at the bottom of the repair base on the implant, fix the entire repair base to the implant through positioning screws, and then make the crown;

Step 4: Install the crown on the healing cap on top of the restoration base for a trial tooth. Adjust the crown based on the trial tooth result, and finally install the crown on the healing cap to complete the implant restoration.

Further optimization: During 3D printing, the 3D model of the repair base is sliced, and then the scanning path is planned. A layer of medical-grade alloy powder is laid on the substrate. The alloy powder is quickly melted according to the slice shape and scanning path, and the repair base blank is obtained by melting and superimposing layer by layer.

Further optimization: During machining, the repair abutment blank is loaded into the tooling to fix the repair abutment blank and ensure that the tool center is consistent with its center. Then, the healing cap, connecting section and lower connecting abutment are processed in turn, and then the marking surface, limit part and limit surface are processed. Then, the step hole in the middle is processed, and finally, the repair abutment blank is removed for deburring to obtain the repair abutment.

The present invention adopts the above technical solution and has the following beneficial effects:

1. In the present invention, the CBCT data of the clinician is used to process the restoration abutment blank and the crown using 3D printing technology, and then a qualified restoration abutment is obtained by machining, and the crown is deburred, thereby improving the processing accuracy of the product, making the treatment effect more accurate, reducing the error of the restoration abutment, and making the patient more comfortable. Because the personalized three-in-one restoration abutment and crown are designed and manufactured before the restoration abutment is implanted, the restoration abutment generally has 5 specifications with a length ranging from 5mm to 10mm. The doctor can select the specification according to the patient's maxillofacial distance, thereby simplifying the doctor's clinical surgery, and can immediately repair special patients, which not only reduces the patient's medical expenses and the number of follow-up visits, improves the protection of the oral cavity, but also reduces the hospital's procurement costs and reduces the workload of warehouse storage.

2. The upper half of the oral implant restoration in the present invention is replaced by one piece instead of multiple consumables, and has the functions of a healing cap, a scanning rod, a temporary restoration abutment, and a permanent restoration abutment. The lower connecting abutment and the implant are placed after the alveolar bone is healed. The restoration abutment does not need to be moved or removed during the entire restoration process, which not only reduces costs but also reduces the probability of misuse of accessories, minimizes the patient's discomfort and infection risk during the restoration process, and shortens the treatment time.
