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%.

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
Dental contact lenses
Porcelain veneers
Ceramic laminates
Onlays and Inlays
Ceramic fragments
Orthodontic treatment

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!
