Application of dental zirconia block in the fabrication of dental abutment

Dental zirconia block is widely used in the fabrication of dental abutment. Its unique performance advantages provide a high-quality material choice for the fabrication of dental abutment. The following is an overview of the application of dental zirconia blocks in the fabrication of dental abutments:

First, the performance advantages of dental zirconia blocks

High strength and wear resistance:

Zirconia blocks have extremely high strength and wear resistance, and can withstand complex biting and chewing forces in the mouth, ensuring the stability and durability of the abutment.

Good biocompatibility:

The zirconia block does not stimulate the oral tissue, does not cause allergic reaction or rejection reaction, and is conducive to the good combination of the implant and the surrounding bone tissue.

Excellent corrosion resistance:

Zirconia blocks are resistant to acid and alkali attack in the oral environment, reducing the risk of damage to abutment materials due to corrosion.

High aesthetics:

Zirconia blocks have a color and semi-transparency similar to natural teeth, and can be perfectly matched with surrounding teeth through dyeing technology to enhance the overall beauty.

Second, the application form of dental zirconia block in the fabrication of dental abutment

Preformed abutment:

Made entirely of zirconia and fixed in shape, it is suitable for some standard implant systems.

Prefabricated abutments have the advantages of being simple and inexpensive to make, but may not be fully adapted to the individual needs of each patient.

Personalized base:

Computer aided design (CAD) and computer aided manufacturing (CAM) techniques are used to personalize the design according to the patient's oral condition and implant position.

The personalized abutment can better adapt to the individual needs of patients and improve the accuracy and aesthetics of the prosthesis.

Two-stage abutment:

It consists of a metal substrate (such as a titanium substrate) and a zirconia superstructure, which are joined together by a binder.

The two-stage abutment combines the strength of the metal substrate with the beauty of the zirconia superstructure and is suitable for some special implant systems or restoration needs.

Third, the specific process of dental zirconia block in the production of dental implant abutment

CAD/CAM Design:

The oral data of patients were obtained by oral scanning equipment, and the 3D design of the abutment was carried out by CAD software.

After the design is complete, the data is transferred to the CAM device for precise machining.

Precision machining:

High precision cutting equipment is used to process zirconia blocks to ensure the accuracy of the shape and size of the base.

It is necessary to strictly control the cutting parameters and cutting depth in the machining process to avoid cracks or deformation of the substrate material.

Coloring and sintering:

The finished zirconia abutment is colored to match the tooth color of the patient.

After coloring, the substrate is placed in a high-temperature sintering furnace for sintering to achieve the required hardness and density.

Bonding and installation:

The sintered zirconia substrate was bonded to the implant to ensure the stability and cohesibility of the substrate.

In the bonding process, it is necessary to select the appropriate binder and control the amount of binder to avoid fretting and leakage between the abutment and the implant.

Fourth, the application advantages of dental zirconia block in the fabrication of dental abutment

Improve the accuracy and aesthetics of the restoration:

The zirconia block has good processing properties and plasticity, and can be made into a precise shape, a close edge and a high aesthetic base.

Enhanced stability and durability of the restoration:

The high strength and wear resistance of zirconia blocks ensure the stability and durability of the abutment, reducing the risk of abutment material damage due to wear or breakage.

Improve patient comfort and satisfaction:

Zirconia blocks have good biocompatibility, no irritation to oral tissue, and can improve patient comfort and satisfaction.

To meet individual needs:

Using CAD/CAM technology, individual zirconia abutments can be created to meet the unique repair needs of each patient.

Fifth, summaryThe application of dental zirconia block in the fabrication of dental abutment has significant advantages and broad prospects. With the continuous development of material science and computer technology, the application of zirconia blocks in the fabrication of dental abutments will be more and more extensive, providing more patients with high-quality and personalized dental implant restoration services.
