Problems solved by technology

When using bone powder particles, problems such as displacement and difficulty in shaping are prone to occur; while using autologous massive bone cut from other parts, it will increase the scope of surgery, increase the surgical risk and postoperative complications in the bone donor area, and autologous bone The block needs to be fixed with non-absorbable material, and the removal of the fixed material in the second operation will increase the pain of the patient
Moreover, the operation process is complicated, which puts forward high requirements on the surgical skills of the surgeon.

Embodiment 1

[0035] Such as figure 1As shown, this embodiment provides a personalized bionic implant structure for synchronously repairing teeth and surrounding alveolar bone defects, including a crown 1 for meshing with normal teeth, and an abutment for connecting the implant part and the crown 2. The bionic tooth root part used to restore tooth defects 3. The restoration part 4 used to restore alveolar bone defects; the abutment is divided into the upper part of the abutment 2-1 bonded to the crown 1 and the abutment passing through the gingival part The lower part 2-2; the crown is designed according to the shape of the occlusal dentition and the mesial and distal teeth, and is made of all-ceramic block 3D cutting, the abutment and the bionic root part of the implant are printed by laser fusion, and the alveolar bone defect is repaired The body uses polymer materials to deposit fusion printing on the basis of implant biomimetic tooth roots. The design of the denser upper layer of the a...

Embodiment 2

[0037] Provide a kind of molding method of the dental implant structure of embodiment 1, and specific method comprises the steps:

[0038] Step 1: Design the crown 1 according to the occlusal relationship between the upper and lower teeth of the patient and the shape of the surrounding normal teeth;

[0039] Step 2: Carry out a CT scan on the patient's teeth and alveolar bone. After the CT scan, process the CT file, divide the tooth part and the surrounding alveolar bone defect part according to different gray values, and process the CT image to obtain Alveolar bone defect model 5 and tooth root model 6.

[0040] Step 3: Design and print the implant bionic root part and abutment according to the patient's tooth root: remove the concave implant bionic root 3 on the basis of the root model 6 of the affected tooth, so as to facilitate its smooth insertion into the extraction socket ; The position indicator mark 3-1 on the mesial and distal part of the bionic tooth root is used f...

Embodiment 3

[0044] Human teeth are mainly divided into single-rooted teeth and multi-rooted teeth. This embodiment provides a single-rooted tooth that is different from the multi-rooted teeth in Embodiment 1 and is suitable for synchronous restoration of single-rooted teeth and surrounding alveolar bone defects. The personalized bionic implant structure, its specific molding method is the same as Example 2.

Abstract

The invention discloses a personalized bionic implant for synchronously repairing tooth and peripheral alveolar bone defects and a forming method of the personalized bionic implant. The implant comprises a dental crown meshed with normal teeth, an abutment used for connecting an implantation part and the dental crown, an implant bionic tooth root used for personalized restoration of tooth defects,and an alveolar bone defect restoration body used for restoration of alveolar bone defects, the implant bionic tooth root part and the alveolar bone defect restoration body jointly form an implant part; the dental crown is designed according to the shapes of involution dentition and mesio-distal teeth, is formed by cutting an all-ceramic block and sleeves the upper part of the abutment; the alveolar bone defect restoration body is consistent with the bone defect form of a patient and has a porous structure. The tooth implantation device can be used for immediate implantation of teeth accompanied by bone defects, and the operation and waiting time of a clinical implantation operation can be greatly shortened; the implant is matched with original tooth roots and bone defects, so that good initial stability can be achieved, and quicker recovery of an operation area and long-term stability of the implant are facilitated.

Description

technical field [0001] The invention belongs to the technical field of oral medical devices, in particular to a personalized bionic implant for synchronously repairing teeth and surrounding alveolar bone defects and a forming method thereof. Background technique [0002] When the residual root and crown cannot be restored and preserved, extraction of the affected tooth and implantation of dental implants is currently the best treatment method. Immediate implant technology can achieve immediate extraction and planting: after the affected tooth is extracted, the implant is placed at the same time. However, the existing commercial implants are cylindrical or conical threaded implants produced in batches, and different lengths and diameters can be selected, but the degree of matching with the shape of the extraction socket is still poor, which will lead to the initial stability of the implant. Unsatisfactory, thus affecting early healing and functional recovery. When these com...
