Precision Machining for the Medical Industry – Dental Implants

Table of Contents

In the past, if you lost a tooth, you would have to wear a large tooth and plate to fill it. Now, with the development of precision machining technology, filling a tooth only requires a dental implant to be installed in the vacant tooth cavity, which can fit the tooth perfectly and work effectively. The demand for precision machining in the field of dental implants is growing, because medical devices and implants require high-quality, reliable components.

Precision Machining for Dental Implants

Importance of Dental Implants in Modern Dentistry

Dental implants have revolutionized the way dentists deal with tooth loss in modern dentistry. These implants offer a long-lasting, durable solution that closely mimics the function and appearance of natural teeth.

Unlike traditional dentures or bridges, dental implants provide improved stability and comfort through precision implant components (e.g., dental screws, implant posts, connectors, etc.) provided by Dental Parts Supplier, allowing patients to eat, speak, and smile with confidence. As a result, dental implants not only improve oral health, but can also significantly enhance overall quality of life.

What is Dental Implants?

Dental implants are artificial tooth roots made of biocompatible materials (usually titanium) that are surgically implanted into the jawbone to support a replacement tooth or bridge. They are the basis for a variety of prosthetic solutions, such as crowns, bridges or dentures.

The precision machining of dental implants ensures that they are securely seated in the jawbone, promoting osseointegration – the process by which the implant fuses with the bone. This integration provides stability and strength, allowing the implant to function like a natural tooth root. Dental implants are popular because they are durable and prevent bone loss, a common problem with tooth loss. They offer a permanent solution to tooth loss, requiring minimal maintenance while providing a natural look and feel.

Dental Implants Components

Dental implants consist of several key components, each serving a distinct purpose to ensure the success and longevity of the implant.

– Implant Post or Fixture: The implant post, also known as the fixture, is the component that is surgically implanted into the jawbone. Made of titanium or other biocompatible materials, it acts as the root of the artificial tooth and is designed to integrate with the bone through osseointegration.

– Dental Screw: The dental screw secures the implant post into place, providing the necessary stability for the implant. Precision machining ensures that the screw fits perfectly, reducing the risk of loosening or failure.

– Dental Abutment: The dental abutment connects the implant post to the prosthetic tooth. It serves as the intermediary component that supports the crown or bridge, ensuring a secure fit and proper alignment.

– Dental Drills: These are specialized tools used during the surgical placement of the implant. Precision drilling is essential to create the correct size and depth of the hole in the jawbone, facilitating successful implantation.

– Connectors, Transfers, and Healing Caps: Connectors and transfers are used during the implant process to ensure accurate placement and alignment of the components. Healing caps protect the implant site during the healing phase, promoting tissue regeneration and integration with the bone.

Precision Machining Techniques Used in Medical Dental Implants Manufacturing

Precision Machining for the Medical Industry

High Precision Bar Turning (Multi-Axis CNC Turning)

This technology involves the use of multi-axis CNC (Computer Numerical Control) lathes to shape and finish cylindrical components such as implant posts and screws. Multi-axis capabilities allow complex geometries to be machined with high precision and consistency. This precision ensures that dental implants fit the jawbone perfectly, promoting successful osseointegration. The ability to machine parts to the tightest tolerances reduces the risk of implant failure while also increasing the lifespan of the implant.

 

CNC Milling

CNC milling is used to create complex shapes and surfaces on dental components such as abutments and connectors. The technology utilizes a rotating cutting tool to remove material from the workpiece, allowing for the creation of fine and precise features. CNC milling is particularly useful for producing parts with complex geometries that require high precision and surface finish.

Advantages of Machining in Dental Implants Manufacturing

The use of precision machining in dental implants manufacturing offers several key advantages:

  • Zero Burrs: Precision machining techniques ensure that components are free from burrs and imperfections, which is essential for preventing irritation or damage to surrounding tissues once the implant is placed.
  • High Precision and Consistency: Machining allows for the production of components with tight tolerances and consistent quality, crucial for the successful integration and function of dental implants.
  • Customization: CNC technology enables the customization of implants to meet the specific needs of patients, ensuring a perfect fit and improved outcomes.
  • Efficiency: Automated machining processes enhance production efficiency, reducing lead times and costs while maintaining high quality.

The Most Common Materials Used to Produce Dental Implants

Dental implants are typically made from materials that are biocompatible, durable, and capable of withstanding the forces exerted during chewing. The most common materials used in dental implants are:

Titanium

  • Usage: The most widely used material for dental implants.
  • Properties: Titanium is known for its excellent biocompatibility, strength, and ability to osseointegrate (bond directly to bone). It is lightweight, corrosion-resistant, and can last for many years.
  • Types: Titanium implants can come in pure form or as a titanium alloy (often mixed with elements like aluminum or vanadium for additional strength).

 

Zirconia (Zirconium Dioxide)

  • Usage: A ceramic alternative to titanium, becoming increasingly popular, especially for patients with metal sensitivities or those seeking a more aesthetic option.
  • Properties: Zirconia is strong, highly biocompatible, and has a natural white color, making it ideal for use in the anterior (front) part of the mouth. It’s also corrosion-resistant and has a low plaque affinity.
  • Advantages: Unlike metal, zirconia doesn’t cause any allergic reactions and doesn’t interfere with MRI or other imaging techniques.

 

Polyether Ether Ketone (PEEK)

  • Usage: Used as a temporary material or in specific situations where a non-metal option is preferred.
  • Properties: PEEK is a high-performance polymer that is lightweight, has good mechanical properties, and is biocompatible. However, it lacks the osseointegration capability of titanium and zirconia, so it’s not commonly used for permanent implants.

 

Tantalum

  • Usage: Occasionally used in implants due to its high biocompatibility and bone integration properties.
  • Properties: Tantalum is very corrosion-resistant and has a unique porous structure that encourages bone ingrowth. However, it’s expensive and less commonly used compared to titanium and zirconia.

 

Stainless steel

  • Uses: Historically used for some implants and dental hardware, such as braces.
  • Properties: Stainless steel is strong and durable, but less biocompatible and more susceptible to corrosion than modern alternatives such as titanium and zirconia.

Why use these materials?

-Biocompatibility: These materials have an innate ability to bond with human bone without causing adverse reactions. This biocompatibility is critical to the success of dental implants, ensuring they are accepted by the body and perform their functions effectively.

-Corrosion resistance: Dental implants must withstand the harsh conditions of the oral environment, including exposure to saliva and varying pH levels.

-Fracture resistance: The materials used in dental implants must be able to withstand significant mechanical loads to support daily eating and speaking functions.
