Open CADCAM system zirconia

Introduction

In the field of dental restoration, open CAD/CAM system has become the standard choice for digital production. In particular, Open CAD/CAM system zirconia, a zirconium oxide material, is widely used in various restorations due to its excellent strength and aesthetic effects. This article will introduce the definition, characteristics, advantages and applications of this product in detail.

2.what is Open CAD/CAM system zirconia?

Open CAD/CAM system zirconia is a zirconia material designed for open computer-aided design and computer-aided manufacturing (CAD/CAM) systems. It is compatible with many different CAD/CAM systems, providing a flexible solution.

2. Features of Open CADCAM system zirconia

High strength: The strength of Open CADCAM system zirconia zirconia material can reach 1100 MPa, which is suitable for posterior teeth and long bridge restorations.

Compatibility: Supports a variety of open CAD/CAM systems and provides a wide range of adaptability.

Excellent aesthetic effect: Due to its good light transmittance, it can present an effect similar to natural teeth, suitable for anterior teeth and complex restorations.

Durability: Excellent wear resistance and crack resistance, ensuring long-term and stable restoration effects.

3. Advantages of Open CADCAM system zirconia

Flexibility: supports a variety of equipment and systems, making it easier for dental laboratories to choose the right tools for production.

Reduce operational difficulty: not limited by equipment, simplifying the production process.

Improve efficiency: The pre-coloring option of Open CAD/CAM system zirconia makes post-staining work easier and saves time.

4. Types of Open CADCAM system zirconia

Standard type: Suitable for routine restoration work, providing high strength and high aesthetic effect.

Ultra-transparent type: Especially suitable for anterior tooth restoration, with high transparency and more natural color.

High-strength type: For long bridge restoration, with higher strength and durability.

5. Application of Open CAD/CAM system zirconia

Open CAD/CAM system zirconia is widely used in:

Single tooth restoration:

Bridge restoration: Due to its high strength, it can effectively support the restoration of long bridges.

All-ceramic tooth restoration: Ultra-transparent zirconium oxide blocks provide natural aesthetic effects for front teeth.

6. production process of Open CAD/CAM system zirconia

The production process of Open CAD/CAM system zirconia goes through many fine processes, and each link is strictly controlled to ensure the high quality and consistency of the final product. Our production process can be roughly divided into the following steps:

Raw material preparation

Before the production begins, we strictly select high-quality zirconia powder. We use the best dental zirconia powder in China, as well as powders from top international suppliers, such as multi-layer powder from TOSOH (Tosoh) in Japan. The choice of raw materials determines the strength and aesthetic effect of the final product, so we strictly test the quality of each batch of powder to ensure that there are no impurities.

Mixing

According to different product requirements, zirconia powder is mixed with appropriate amounts of stabilizers and colorants. This process requires precise control of the ratio to ensure the uniformity and stability of the material. We use automated mixing equipment to ensure the accuracy of each mixing.

Cold isostatic pressing

The mixed zirconia powder is loaded into a mold and cold isostatically pressed. The powder is pressed into a blank block of a predetermined shape by uniform pressure. The cold isostatic pressing process ensures the density and uniformity of the material, laying a good foundation for the subsequent sintering process.

Pre-sintering

The pre-sintering process further improves the stability of the blank. The pre-sintering process can eliminate the residual stress in the zirconia blank and improve the quality of the finished product after sintering. We precisely control the temperature and time of pre-sintering according to the requirements of different products.

Sintering

In the high-temperature sintering furnace, the pre-sintered zirconia blank is further heated to above 1200℃, and the material is densified and the required hardness is obtained through high-temperature sintering. The fine control of sintering temperature, time and atmosphere is a key step to ensure product quality. We use internationally advanced sintering equipment to ensure that each batch of products meets high standards.

Cooling and processing

The sintered zirconia block needs to go through a natural cooling process to ensure the stability of its internal structure. After cooling, it enters the post-processing stage. According to customer needs, we can perform fine cutting and grinding to ensure that the size and shape of the zirconia block meet the standards.

Quality inspection

Each batch of products will undergo strict quality inspection before leaving the factory, including strength testing, appearance inspection, dimensional accuracy, etc. We ensure that each zirconia block meets the standards of international certifications such as ISO 13485, FDA and CE. Through quality control, we ensure that each product can provide a long-lasting and stable restoration effect.

Packaging and Shipping

After completing all processes, the product enters the packaging stage. We use high-quality packaging materials to ensure that the product will not be damaged during transportation. The delivery cycle of regular products is 1-3 working days, and the delivery time of customized products can be communicated according to needs.

7. Cooperation Methods

We provide OEM and ODM services, and customers can customize the size, color, etc. according to their needs. Whether it is bulk ordering or single customization, HONCHON can provide flexible cooperation solutions.
