    Step-by-Step Process of 3D Printing Dental Implants

Let's elaborate on the process step-by-step to understand the workflow in creating these dental implants.

   3D Scanning of the Oral Structure

The first stage starts with an intricate scanning of the patient's oral region, employing state-of-the-art 3D dental scanning technology. Unlike traditional dental impressions, this dental scan creates a more detailed and accurate digital impression of the teeth and gums. This digital 3D model is instrumental in designing custom implants that perfectly fit the patient's teeth and jaw structure, enhancing the likelihood of successful implant placement.

After 3D scanning, you will need to import the scans into a 3D CAD software and fix any meshes that has issues and even customize it further. There are a lot of programs available that can do the job but we recommend using SelfCAD. SelfCAD is an all in one 3D designing software that supports most of the file formats of 3D scanners and you can not only use it to fix the scans but you can use it too prepare it for 3D printing.

To start working on your files, you will need to first of all import them. You can do this by going to File > Import.

Once you import it you can start working on it based on your needs. For example, if there are issues with it that needs cleaning and fixing, you can use the Magic Fix tool of SelfCAD to fix it and ensure that it is 3D printable. You can access it from the Tools section of the software.

Once you select it, you will see a slider appearing on the left section and you can move it to the left or right until you get the desired results.

When you are comfortable with the results you can preview and finalize. You can also fix issues like gaps and holes in the dental scans using SelfCAD. You can check out our article on 3D printing dentistry to learn more on how you can achieve this.

To prepare your designs for 3D printing, you can use the in-built online slicer of SelfCAD. It is easy to use and it supports most of the common FDM 3D printers. You can access it on the top-right section of the toolbar. The video below demonstrates how you can use SelfCAD to slice your designs.

  Choosing the Suitable Material

During the slicing process, you have an option to choose the material that you want to use to 3D print your designs. The preferred material should be biocompatible, signifying its capability to function in proximity to living tissues without causing adverse reactions. Typically, Titanium and specific medical-grade polymers find favor due to their strong compatibility with the body and sturdy nature.

 3D Printing the Implant

The creation process begins by sending the digital model to a dedicated 3D printer. The printer deploys the selected material, building the implant layer by layer in an additive process to match the original digital design precisely. This exacting process ensures the implant will fit perfectly in the patient's mouth.

Post-Processing

After printing, the implant undergoes a series of post-processing steps to ensure it meets the highest standards. This includes smoothing rough edges, sterilizing the implant for safe use, and completing other finishing tasks that guarantee the implant is ready for surgery. 

This step-by-step process, from high-tech scanning to expert manufacturing, culminates in a dental implant designed for peak performance and patient comfort.
