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:
