Digital dental design

The realization of digital dental prosthesis design is possible thanks to advances in technology in recent years. These technologies are certainly making treatments faster, more precise and with better predictability of results. This applies to both fixed prostheses on dental implants and prostheses on teeth.

It is now possible to see and perfect the result of the treatment on the computer screen before it is finished

ImplArt is continually investing in acquiring the main technologies developed in this sector. They allow us to carry out what we call a digital smile project, i.e. we use a computer to design one or more teeth (choosing their shape and shade) and to plan implant surgeries.

The latest addition is the Cerec Primemill milling machine, which allows crowns to be made with even more detail and even more precise results.

Modern technologies are constantly advancing, always seeking to combine greater patient comfort, speedy treatment and superior aesthetic results. In addition, there is a variety of work available such as crowns, blocks, fixed prostheses with pontics, dental lenses, prostheses on implants.

Photographs of the patient and software are used to plan and make functional and aesthetic changes to the smile, such as adjusting occlusion, the shape and shade of the teeth.

According to scientific research carried out by Dr. Roberto Markarian, Clinical Director of ImplArt, the use of digital prostheses speeds up the delivery time of the work by up to 5x, and increases the degree of patient satisfaction by 80%.

Cerec 3D and Ceramill Motion II

Systems developed for dental laboratories in which we can make the digital design of prostheses, plan and execute teeth using 3D printers. The technique used in digital smile design is called CAD/CAM (computer-aided design). It consists of 4 phases:

Intraoral Scanner – This is a high-precision camera used to capture images inside the patient’s mouth. The images are so lifelike that they show minute details such as the tone and texture of the gums and teeth.

Processing software – The images captured by the camera are sent to specialized software that creates a three-dimensional digital mould. In this processing phase, our team has the freedom to make adjustments, such as altering the shape and tone, in order to leave the piece with the characteristics that best match the patient’s needs. The computerized design can be superimposed on photographs of the patient to make it easier to understand the proposed treatment.

Milling – Equipment that works in a similar way to 3D printers. It receives information from the project and executes it accordingly. This compartment has robotic arms that mill raw ceramic blocks until they reach the shape of the designed part.

Ceramic kiln – The designed piece is taken to a high-temperature kiln to undergo a process called ceramic sintering. This phase is what gives the piece strength, shine and shade so that it has characteristics very close to natural teeth.

The main advantages of digital prosthesis design are:

Precision – the design of each tooth is made according to the patient’s needs. Once finished, they are the same size and shade as the original design. The fit is usually excellent.

Predictability – the software we use is sensitive enough for us to create a three-dimensional mold of the patient in great detail. Both our professionals and the patient can visualize the project on the computer screen, thus being able to predict the outcome of the treatment very accurately.

Speed – this system allows us to skip steps that could previously only be done manually, meaning that prosthetic work has become faster. We can perform teeth in a few days or even a few hours through the Day Clinic*.

Repeatability – The system allows you to repeat jobs and even make an identical copy of a prosthesis or tooth.

The installation of a provisional made with digital smile planning allows the patient to concretely visualize how their treatment will look before they begin the more invasive procedures in the mouth. This is known as a smile test drive or digital mockup. Treatments that can be planned on a computer:

Dental aesthetics
Oral rehabilitation
Implant surgery – computer-guided surgery
Porcelain crowns with zirconia structure – Metal Free
Porcelain crowns with metal structure – Metalloceramics
Crown on implants
Crown on teeth
Full dentures
Partial prosthesis

Pure porcelain crown for highly aesthetic implants

The digital all-porcelain crown is a highly efficient ceramic system used to make prosthetic crowns for dental implants.

What are digital pure porcelain crowns made of?

Lithium disilicate ceramics have aesthetic and resistance properties comparable to natural teeth. They are the best and most technologically advanced materials for achieving aesthetic teeth because they are white and translucent, which makes the crown look natural even in the brightest of environments.

e.max ceramic was developed for use in Digital Dentistry Systems, with a 3D printer that sculpts dental prostheses. With this system, the all-porcelain crown can be made quickly, with more strength and naturalness than other materials made by hand.

*Cemented pure porcelain crown indicated for cases with a greater need for aesthetics*

What is the best material for pure porcelain digital prostheses?

The digital porcelain crown is made as a monoblock, i.e. it has no internal reinforcement layers, as the computer will create the crown from a prefabricated block of dental porcelain.

digital prosthesis design — *Example of raw material blocks for computerized dental porcelain EMAX CAD*

The Pura Digital porcelain crown is an evolution in the materials used in dental prostheses. With it, it is possible to reproduce details that make the prosthesis similar to natural teeth. With the Cerec System, the e.max crown is made more quickly and precisely, because it is designed on a computer and sculpted by robots.

The main advantages of modern porcelain crowns:

High resistance to dental fracture and durability;
Very aesthetic look, comparable to a natural tooth;
Range of blocks with different colors and types of resistance for different uses;
Stain-resistant material;
It can be made using the Metal Free technique (no metal in the internal structure). This makes the crown look translucent and much more aesthetic in bright environments.
It can be designed and built quickly thanks to the Cerec system.

To make digitalpure porcelain crowns , we use CAD/CAM techniques:

1 – Intraoral scanner: It all starts with the digital molding of the dental implant with a high-precision color camera that takes images of the oral interior and sends them to the computer.

2 – Computer and software: receives the information captured by the intraoral scanner and carries out the simulation and personalized planning of the dental crown using three-dimensional images.

3 – Machine manufacturing: robots mill the e.max ceramic block based on the computerized design until the shape of the crown is achieved. The result is certainly a piece that is strictly compatible with the patient’s needs.

It is common for a temporary crown to be made before finalizing the permanent tooth to test whether the computer modeling is correct. Immediately after milling, the piece undergoes a crystallization process at approximately 850°C for 20 to 30 minutes and acquires high resistance, shade and translucency.

When the crown is finished, it is attached to the previously installed dental implant. For your convenience, the Cerec System and e.max ceramics are available at ImplArt Dental Clinic in Brazil. As an alternative to the pure porcelain crown, we now have an even more resistant material, translucent pure zirconia.

If you have any questions about this or other techniques and prices, please make an appointment or contact us. We are located in the Paulista Avenue area/Downtown of São Paulo. We will be happy to assist you.

Cerec 3D – Emax Cad crowns

Emax Cad crowns are prostheses used in oral rehabilitation and dental restoration to cover, protect and strengthen teeth that have been extensively damaged by decay or root canal treatment.

Ceramic crowns in Emax Cad

Developed by the German company Ivoclar, the technical name of the Emax material is lithium disilicate and it has the ability to offer high aesthetics and high resistance.

Dissilicate porcelain is classified as a glass porcelain, or glass-ceramic, with diverse applications for dental prostheses on teeth and implants, contact lenses, porcelain blocks, individual crowns on structure. In other words, these are applications for single teeth or up to 3 teeth. For larger dental prostheses, we use other types of dental porcelain, such as translucent dental zirconia.

EMAX crown applications

Dental crowns can also be placed on dental implants to replace missing teeth. They can be made from different materials such as temporary resins, but the main one is Emax Cad ceramic. What are the main advantages of the Emax Cad crown?

High resistance and durability;
Very aesthetic look, similar to a natural tooth;
Range of blocks with different colors and types of resistance for different uses;
Minimally invasive restorations;
It can be made using the metal-free technique (no metal in the internal structure). This makes the crown look translucent and much more aesthetic in bright environments.

emax crowns — The digital emax crown is milled by robotic machines in the blue phase, when the material is still soft. The material is then crystallized at over 700 degrees to achieve the final color. On the right, it has received the final polish that guarantees the smoothness of the structure and final pigmentation (even in black light environments).

Emax porcelain crowns in digital dentistry – how are they made?

ImplArt Odontologia is equipped with the modern Cerec 3D system with CAD/CAM technology, which simulates and digitally plans the treatment right through to making the Emax Cad ceramic crowns. The system is complete and consists of three units:

1 – Intraoral scanner: high-precision color camera that makes digital molds of the patient’s teeth and sends them to the computer.
2 – Computer and software: receives the information captured by the intraoral scanner and carries out simulation and personalized treatment planning using 3D images.
3 – Machining bay: robots mill the Emax Cad ceramic block based on the computerized design until the shape of the crown is achieved. The result is a piece that is strictly compatible with the patient’s needs.

When the milling is complete, the piece undergoes a sintering process at approximately 850°C and acquires high strength, shade and translucency. The CEREC 3D system certainly speeds up treatment, even allowing it to be carried out and finalized in Day Clinic planning.

With it, it is possible to make crowns and restorations that are very precise and customized to the needs of each case. Contact us and make an appointment to find out if your case could benefit from this technique.

We’ll be happy to solve your problem in our specialized clinic. We also offer translucent zirconia crowns, a new type of dental porcelain that is even more resistant than Emax.

Dental zirconia: better aesthetics for dental prostheses

There are different materials that can be used to build a dental prosthesis, the main ones being: resin with a metal internal structure (metalloplastics/Branemark protocol), ceramic with a metal internal structure (metalloceramics) and the most aesthetic option which is ceramic with a metal-free dental zirconia internal structure (metal free).

Therefore, among the possible materials for dental prostheses, we have:

resin with an internal metal structure – this is known as metalloplastic or Branemark protocol,
ceramic with an internal metal structure – this is called metal-ceramic,
the metal-free dental zirconia ceramic.

The most aesthetic option is ceramic with a metal-free dental zirconia structure, also known as metal free.

The evolution of aesthetic dentures

Most total or partial infrastructures are made with metal alloys that play the role of mechanical and functional support. However, their dark color can compromise the final aesthetics, especially in areas that are more apparent and important to patients.

As a result, metal-free ceramic structures are gaining ground, mainly because they achieve a more aesthetic result and because of their biocompatibility, resistance and stability.

Dental ceramics and zirconia are considered the most advanced materials because they do not contain metals in their composition, which provides an aesthetic dental prosthesis that is much more similar to natural teeth.

Zirconia teeth can be single, bridged or full-arch, installed on teeth or on dental implants.

Dental zirconia is a white, resistant ceramic material used to build the structure of the prosthesis. A layer of porcelain is applied to this structure, which makes the prosthesis similar to natural teeth in terms of translucency, texture and shade.

As zirconia is white, the prosthesis has a similar shade and translucency to natural teeth, even when exposed to light.

New types of more translucent dental zirconia allow for the complete fabrication of dental prostheses by computer, without the need to apply porcelain manually.

The shade of zirconia is comparable to natural human dentin. In contrast, the same result cannot be achieved with a prosthesis containing a metal framework.

Zirconia – far superior aesthetics

Metal-ceramic prostheses, when exposed to light, have a slightly darkened core. In addition, over time, grayish lines may appear on the gingival margin.

This is because bone and gum changes naturally occur over the years, and this remodeling can expose a small portion of the metal of the prosthesis and thus cause aesthetic damage to the smile.

Another advantage of zirconia is that prostheses made from this material are completely computer-engineered and executed on 3D printers using Cad/Cam systems. This allows prostheses to be made more quickly and accurately.

For your convenience, ImplArt Odontologia has its own digital prost hesis laboratory that develops dental zirconia prostheses. Make an appointment and find out if this technique is right for you. We would be delighted to hear from you!
