These models are used to plan and discuss  the design and fabrication of dental restorations between patients and clinicians and between dental technicians. This provides dental professionals with an accurate model that can be visually and physically examined to gain a clearer understanding of the patient's anatomy before commencing any treatment.
 
Surgical Guides
3D printing technology enables the creation of highly accurate surgical guides for dental procedures. 3D printing technology allows for the creation of extremely accurate surgical guides for dental procedures. These guides are designed based on digital information of the patients, giving dentists a detailed roadmap for implant placement and other surgical interventions. The result is increased precision during procedures, shorter surgery times, and reduced risks of complications. This advancement is particularly beneficial for complex cases where precise implant positioning is crucial for long-term success.

Gingival Masks
One of the significant uses of 3D printing in dentistry is to fabricate gingival masks. 3D printed soft tissue models are becoming a requirement for fabricating implant-supported prosthetics as these workflows become digital. Using the soft resin as a base, dental professionals can now print gingival masks easily.
 
Dental Crowns and Bridges
Utilizing dental 3D printers enables the precise fabrication of removable crowns and bridges. With data collected from intraoral scanners, dental professionals could utilize 3D printing technology to print temporary crowns and bridges with the resin. The advent of 3D printing has markedly enhanced the crown and bridge manufacturing process in dentistry.
 
Customized Prosthetics and implants
One of the most significant applications of 3D printers in dentistry is the creation of customized restorations and implants. Traditional methods often involved a time-consuming and less precise process of crafting dental prosthetics. 3D printing enables the creation of patient-specific dental implants, crowns, bridges, and dentures, assuring a flawless fit and maximum functioning. This level of customization not only improves patient comfort but also enhances the aesthetic results of dental restorations
 
Orthodontic Models And Aligners
In orthodontics, 3D printing has streamlined the process of creating models for treatment planning and the fabrication of customized aligners. Orthodontists can now use digital scans of a patient's teeth to produce accurate 3D-printed models, allowing for more efficient diagnosis and treatment planning. Furthermore, the use of 3D printing to create personalized aligners has gained popularity as a substitute for traditional braces, providing patients with an orthodontic treatment that is both more visually beautiful and more comfortable.

Dental milling machines have revolutionized the field of dentistry, providing precise and efficient solutions for fabricating dental restorations. These equipment are essential in modern dental laboratories because they enable the precise manufacture of crowns, bridges, and other dental restorations. In this article, we explore more about dental milling machines.
What Is A Dental Milling Machine?
A dental milling machine is a specialized piece of equipment used to automate the creation of dental restorations from a variety of materials such as ceramics, metals, and resins. These machines use Computer-Aided Manufacturing (CAM) software to convert digital information about a patient's teeth into precise physical restorations.

Dental milling machines begin their process with computer-aided design (CAD) software. Dentists and dental professionals use this program to produce digital models of intended dental restorations. These digital designs serve as the blueprint for the milling process.

Following the design phase, computer-aided manufacturing (CAM) software takes over. CAM software provides tool paths based on the digital design, instructing the milling machine to accurately sculpt the restorations from selected material. Zirconia, glass ceramics, metals, Peek, PMMA, etc. are among the materials that dental milling machines can process. These materials often come in the form of pre-fabricated blanks/ blocks that the milling machine carves into the final restoration.
Types Of Dental Milling Machines
Dental milling machines come in three distinct types, each tailored to specific processing methods: dry, wet, and combination dry/wet models. The following is an overview of each type.
Dry Type
The dry milling method eschews the use of water or coolant during the processing phase. This technique is particularly advantageous for working with materials such as zirconia, resin, and PMMA. Small-diameter tools in the 1mm range are particularly effective in cutting these softer materials, allowing for delicate modeling and accurate processing. However, when tackling harder substances, the utilization of small-diameter tools is limited due to concerns like breakage and extended machining times.
Wet Type
Employing water or coolant during the processing stage, the wet milling method serves to minimize frictional heat, especially when polishing hard materials like glass-ceramic and titanium premills. With increased demand for stronger and more visually pleasing dental components, the wet technique is critical to getting the required results.
Combination Dry/Wet Type
The combination dry/wet milling machine serves as a dual-use model compatible with both processing methods. It provides the flexibility of treating a wide range of materials in a single machine, fulfilling your diversified milling needs.
Conclusion
Dental milling machines have become indispensable devices in digital dentistry, enabling the production of high-quality and customized dental restorations efficiently and accurately. Whether in a small clinic or a big laboratory, this equipment helps to streamline the workflow by delivering dependable, visually acceptable, and digitally controllable solutions to the dental technicians.

A: Hardness is a measure of a material’s ability to withstand impacting and abrasive forces, yet it also occupies a unique mechanical intersection between toughness and strength. Zirconia are extremely tough with outstanding impact resistance qualities. This denotes a balance between hardness, toughness, and strength which enables zirconia ceramics to withstand extremely high amounts of friction.

A: Aconia® blanks are made by CIP( Cold Isostatic Pressing) processing technology. Cold isostatic pressing is the most accepted procedural technique for shaping Y-TZP and produces stable, chalk-like non-sintered green-stage objects with a very high primary density. Aconia® blanks have the proper density. High-density blanks are easily damaging the burs during the milling. Insufficient density blanks will cause margin chipping in a higher percentage.

A: Fracture toughness is used to describe an ability of a material with a crack in it to resist further fracture. The higher fracture toughness of zirconia, the lower probability of the crack spreading in restorations. So the high value of fracture toughness ensures superior clinical long-term performance, which means the restorations can be long-term lasting. That is why fracture toughness is a clinically significant value. Aconia® HT plus has fracture toughness more than 9 MPa · m1/2. This highlight has helped more and more technicians to achieve more success in their work.

For the dental zirconia, high flexural strength means wider indications, so it can be used to make restorations with more units. On the other hand, high flexural strength also affects the thickness of the restoration walls. A high-strength material allows a low wall thickness. Aconia® provides a wide range of zirconia blanks with different flexural strength, which means you can select the best solution for balancing aesthetics and strength.

!

Flexural strength is a term that is frequently used in dental zirconia products, and it has been considered as a key feature of the stability of the material. In general, flexural strength indicates the resistance of a material against deformation. The commonly used flexural strength testing method is a 3-point testing method & 4-point testing method. The values measured from different testing method are not comparable. All Aconia® zirconia applies with the 3-point testing method.

Crystal phases are used to describe the crystalline structure of substance under different temperatures. ZrO2 has three crystal phases: monoclinic, tetragonal and cubic. The monoclinic phase is stable at room temperatures up to 1170 ℃, the tetragonal at temperatures of 1170-2370 ℃ and the cubic at over 2370 ℃. About Aconia® zirconia, after sintered, the zirconia is mainly combined with tetragonal and cubic phases. The different percentage of crystal structures determines the different properties of sintered zirconia.

Yttria-stabilized zirconia (YSZ) is a zirconium oxide based ceramic, in which the particular crystal structure of zirconium oxide is made stable at room temperature by addition of yttrium oxide. The addition of yttria (Y2O3) as a stabilizing agent in zirconia allows the zirconia can be stable at room temperature with the tetragonal phase or the cubic phase. The different yttria (Y2O3) percentage in zirconia will lead to different ratio of tetragonal form and cubic forms in the final restoration, which come with the different strength and translucency of zirconia restorations. (eg. 3YSZ-with 3 mol-% Y2O3 partially Stabilized ZrO2, Yttria Stabilized Zirconia). Aconia® blanks are Yttria-stabilized zirconia.
