What’s the need of switching to digital?

The conventional techniques in dental care have worked excellent for decades.

 

However, if dental professionals are looking for a simpler, faster, more accurate, and more efficient workflow, there is a large potential in digital dentistry.

 

When we start thinking about digitalization of our practice or laboratory, many dental professionals give concentrated consideration to the individual machines that they want to integrate into their practice.

 

The challenge is to create an individual solution that takes account of all aspects of the internal and external workflow in the best way possible.

 

A fully digitalized workflow brings many advantages to the table for both dentists and dental technicians but also for the patients.

Dentist happy doing digital

 

For a dentist, the advantages of taking a digital impression of the patient’s teeth using an intra-oral scanner are that the scanning itself only takes a few minutes and provides an immediate 3D impression with very detailed information about the patient’s teeth.

 

It allows for the dentist to zoom in on the patient’s teeth and discuss the case with the patient straight away.

 

As the impression is digital, the dentist can then send the file to the dental lab in seconds – the same as sending an ordinary email.

 

Welcome to the world of a much more convenient dental experience with the teeth scanned with an intra-oral scanner.

 

A conventional moulded impression involves bad-tasting impression material inside the patient’s mouth for quite some time, that is often uncomfortable and, worst case, activates the gag reflex.

 

The intra-oral scanner is much more comfortable and requires only a few minutes of the patient’s time. With direct access to the digital impression on the computer screen, the patient will get a much clearer picture of their own case.

 

It also allows for the patient to ask questions related to the impression and discuss further treatment with the dentist.

 

Digital radiography as well as three-dimensional (3-D) cone beam radiography allows an enhanced level of diagnosis and, ultimately, treatment decision-making.

 

An increased range of restorative options becomes available with computer-aided design/computer-aided manufacturing (CAD/CAM) coupled with intraoral and laboratory scanners for conventional impressions.

 

These options include: biocompatible, high-strength, all-ceramic zirconia frameworks for full-coverage crowns and fixed partial dentures; customizable implant abutments and, more recently, milled titanium copings for titanium-porcelain crowns and bridges; milled titanium bars for implant-retained hybrid dentures; and hybrid combination abutments with titanium implant inserts and zirconia abutment bodies.

 

Titanium has been proven highly successful and biocompatible in implant placement, and is both economical and a biocompatible replacement for existing dental materials.

 

Another system, called STL (Stereolithography) and RP/RM (Rapid Prototyping/Rapid Manufacturing), can, in essence, “print” a coping using particles of zirconia, ceramic, and metals, including gold.

 

This process is similar to a laser printer placing powdered toner on a sheet of paper. Imagine the toner being layered by the printer”s head passing over the paper again and again.

 

These new systems work like that and, with each layer, a laser melts/welds the particles together. The days of wax and cast might be numbered.

 

The laboratory is no longer a place; it is instead to a large degree, virtual and fluid entity. It is hence no doubt to call CAD/CAM a Virtual Laboratory.

 

A few CAD/CAM SYSTEMS:

CONCLUSION

 

While a traditional workflow includes many different steps, the digital workflow only includes a few.

 

Minimising the number of steps also minimises the risk of errors.

 

Digital dentistry simplifies the entire workflow.

It also helps to improve the communication between dentists and dental technicians as well as the communication with patients.

 

Using the digital techniques such as CAD/CAM, allows for a faster and more efficient workflow.

Also having the patients with a more pleasant dental experience.
