Company / 3D technology in dental clinics

3D scanners, CAD software and 3D printing are some of the most commonly used digital technologies in dentistry.

Dentist Itamar Friedlander reveals the benefits of 3D technology in dentistry: personalized, less invasive, smaller and more precise treatments.

According to a global Flash market study promoted by the dental sector of the Spanish Federation of Health Technology Companies, it indicates that 60% of dental clinics in Spain are betting on digital technologies to fuel the recovery of the sector and achieve the values ​​of consumption . before the health crisis. Similarly, according to a study by SmartTech Publishing, 3D printing in dentistry is growing at 35% annually and will reach $9.5 billion in 2027, taking into account equipment, materials and 3D printed parts.

One of the advantages offered by 3D technology in dentistry is to provide the patient with a solution to their problem, in some treatments, in just 24 hours, since it treats prosthetic procedures in a personalized and minimally invasive way. In this line, since the therapeutic procedure can be planned virtually, the professional treats his patients more efficiently, reducing intervention time and increasing clinical success: “Virtual planning of dental implants allows us to design a guide surgical with great precision”. In this sense, Friedlander “highlights the possibility of offering different treatment plans to the patient and you can see what the result will be before it begins”. In addition, “it improves communication with patients, because they can see the results from the start”. On the other hand, there is less waste in the material, because 3D printing is an additive technology, this means that layers of material are added in depending on the requirements of each geometry.

What does the dentistry workflow look like when using 3D technology?

The main pillars of these new working methods are 3D scanners, design software (CAD) and 3D printing. Dr. Itamar Friedlander explains what each technique involves and how it affects workflow in the clinic:

3D scanning. In the case of a scanner, it can be an intra-oral, dental or external scanner of the patient’s face. With intraoral scanners, digital replicas of the teeth can be obtained directly, while with external scanners or facial scanners, a replica of the patient’s facial surface is obtained and this data can be combined with images obtained by computed tomography. (a scanner). All this information will be used to plan rehabilitation or complex cases of orthognathic surgery. Friedlander says, “With today’s scanners, you can get virtual models of the patient, which you can print out, use with software designed to plan treatments. All these new technologies help us to perform dental aesthetics and facial care. assistance in the planning and integration of the aesthetics of the

Design and data processing software. Thanks to this system, digital models of different fragments are reconstructed. With the digital model, the patient’s prosthesis can be digitally designed, the placement of implants can be planned and even the teeth “set” so that the teeth can be worn in the intended position.

3D printer and milling machine. If you want to “materialize” these models, the models are printed with a 3D printer, “the most common are resin printers that use different 3D printing techniques”, he adds to the Friedländer Clinic. So, “once you scan the patient, you can design a crown on a tooth, for example. Later, you can weld this crown. With a ceramic block and some drills, the milling machine polishes this block until there is only one crown. A very precise dental restoration”, he underlines.

Challenges of Virtually Planned Medical Procedures

Currently, the main challenge lies in obtaining a biocompatible material allowing the direct impression of temporary and permanent teeth without intermediate steps. On the other hand, from Friedlander, he points out that there are cases where digital technology still does not overcome analog processes. “For example, the characterization of ceramics used for certain very delicate aesthetic treatments or veneers still requires them to be done manually,” he explains. In addition, they point out that “3D technology remains a tool to achieve greater precision in processes, as well as to make them smaller and more predictable. Not everything may be digital. The digital technology used when treatment is needed.

About Friedlander Dental Clinic

The Friedlander dental clinic was founded 5 years ago by Itamar Friedlander, orthodontist and ATM specialist. The center is located at Carrer Gran de Gràcia 110 in Barcelona and has a team of 12 dentists specialized in various fields who work according to the slow philosophy, a method that adapts to the needs of each patient with a stable and long-lasting focus. on providing durable solutions. The clinic occupies 400m2, has 9 consultation rooms and a hospital-grade operating theater with a sterile circuit. The Friedlander dental clinic team always works hand in hand with the most advanced technology in the field to perform more accurate diagnosis and treatment and currently has a CBTC that allows 3D and CAD-CAM X-rays to be taken for all its technology. Speciality. In the same vein, the dental center also has an intraoral scanner, a 3D printer for model making, a CEREC milling machine for carrying out endodontics, restorative dentistry and periodontics and a Zeiss dental microscope. In addition, the professionals of the clinic are also trainers of other professionals at the national and international level.
