Problems solved by technology

Implants with standardized sizes in traditional forms are usually inconsistent with the shape of the extraction socket, resulting in the gap between the implant and bone tissue after immediate implant surgery, making it difficult to obtain good initial stability
Bone grafting or bone augmentation surgery is more traumatic and expensive, and it will also increase the treatment cycle and the risk of potential complications for patients
Most of the traditional implant machine tool processing methods belong to subtractive manufacturing. On the one hand, it will cause material waste and time-consuming. On the other hand, it cannot make products with complex structures. Moreover, the casting process is cumbersome, prone to shrinkage cavities, incomplete casting and other defects, resulting in The mechanical properties are low, which affects the quality of castings

Embodiment 1

[0038] A 3D printing method for personalized porous-layer multi-root implants, such as figure 1 shown, including the following steps:

[0039] Step one, scan the object and get the data.

[0040] Step 2: Use MIMICS software to separate and reconstruct the data obtained in Step 1 for the scanning area, and obtain the three-dimensional models of the root, socket, crown and dentition area of ​​the subject to be extracted.

[0041] Step 3: Use Magic software to edit the 3D model in step 3, digitally design the root, abutment and crown of the implant and adjust the printing parameters as the implant model to be printed.

[0042] Step 4: Copy the data of the implant model to be printed in Step 3 to a 3D printer for printing to obtain a personalized porous-layer multi-root implant.

[0043] Step 1 is specifically to scan the maxillofacial region of the target with a CBCT scanner to obtain dental and maxillary bone data.

[0044] In step 2, MIMICS software is used to separate and r...

Embodiment 2

[0055] A 3D printing method for personalized porous-layer multi-root implants, such as Figures 1 to 5 shown, including the following steps:

[0056] (1) Data collection

[0057] Scan the maxillofacial region of the target with a CBCT scanner to obtain dental and maxillary data.

[0058] (2) Data processing

[0059] Use MIMICS software to separate and reconstruct the data obtained in step 1 of the scanned tooth extraction area, and obtain the three-dimensional model of the tooth root, extraction socket, crown and dentition area of ​​the subject to be extracted.

[0060] (3) Specific design of personalized multi-root implants with porous layers

[0061] Use Magic software to edit the 3D model in step 3, digitally design the root, abutment and crown respectively and adjust the printing parameters, as the implant model to be printed. The specific design of the root, abutment and crown is as follows:

[0062] The root is designed to include a root tip and a root body composed...

Abstract

The invention discloses a 3D printing method of an individualized porous-layer multi-tooth root implant. The 3D printing method comprises the following steps of step one, scanning an object, and acquiring data; step two, aiming to a scanning region, using an MIMICS software to carry out separation and reconstruction on the data acquired in the step one to obtain a three-dimensional model of a tooth root, a tooth fossa, a corona dentis and a dentition region to be pulled out of the object; step three, utilizing a Magic software to edit the three-dimensional model in the step three, carrying out digital design on a root, an abutment and the corona dentis of the implant, and regulating printing parameters to obtain a model of the implant to be printed; and step four, copying the model of the implant to be printed in the step three into a 3D printer for printing to obtain the individualized porous-layer multi-tooth root implant. The method has the advantages of high manufacturing accuracy, shortening in planting treatment period, reduction in planting cost and improvement in stability of the tooth root implant.

Description

technical field [0001] The invention relates to the field of dental implants, in particular to a 3D printing method for a personalized porous-layer multi-root implant. Background technique [0002] Oral implant surgery is a surgical procedure in which oral implants are implanted into the jawbone in the edentulous area, and artificial crowns are made on the implants to replace the missing natural teeth to exercise their physiological functions. According to the length of implant treatment, it can be divided into immediate implant surgery and delayed implant surgery. [0003] Delayed implantation is currently the most common surgical method in clinical practice, that is, after 3-4 months of tooth loss or extraction, the implantation operation is performed after the growth of soft tissue and bone tissue in the edentulous area recovers to a certain extent. The course of implantation treatment is relatively long, and it will cause secondary surgical trauma. Immediate implantati...
