Dental technology has come a long way by offering cutting-edge
diagnostic and therapeutic technologies to dentists around the
world. Gone are the days when dentists relied solely on
two-dimensional X-rays or waited days before their patients'
restorations arrived from the laboratory.
Thanks to 3D technology, dental treatment today is much less
time-consuming, more comfortable, and most importantly, more
aesthetic than ever! This article explains how 3D printing
technology has revolutionized dentistry and how it will
benefit dental patients.
The 3D Revolution in Dentistry
3D X-Rays
- Diagnosis and treatment planning: many dentists in the U.S. have already said goodbye to old 2D X-ray machines. 3D X-ray technology allows faster processing of X-ray images and provides dentists with information that helps them make better treatment plans for their patients.
- Implant dentistry: Cone Beam CT (CBCT) technology has allowed dentists to see a three-dimensional image of the bone structures where implants need to be inserted. Dentists can use this technology to precisely determine the quality and density of the jawbone and visualize any anatomically essential structures nearby.
- Diagnosis of oral diseases: early diagnosis of lesions or swellings in the deeper parts of the face or neck was a challenging task when dentists had to rely on conventional X-ray images. With 3D X-rays, dentists can now visualize even the smallest inflammations or pathologies, and treat them, long before they cause permanent damage.
3D Digital Impressions
Conventionally, dentists had to take physical impressions of patients, which were then sent to the laboratory for the fabrication of the required prosthesis. Those days are over, says the American Dental Association. Your dentist can now take 3D digital impressions of your teeth using a high-resolution intraoral scanner. Then, your dentist simply enters these digital impressions into software and designs the desired prosthesis, before manufacturing it with a 3D printer.
3D Printing
- Dental restorations: Cone Beam CT (CBCT) technology has allowed dentists to see a three-dimensional image of the bone structures where implants need to be inserted. Dentists can use this technology to precisely determine the quality and density of the jawbone and visualize any anatomically essential structures nearby.
- Implant surgical guides: Dentists often use surgical guides to ensure that implants are inserted in the precise, pre-planned location. These surgical guides were previously manufactured in dental laboratories, but not anymore. Now these surgical guides can be 3D printed chairside, which are not only more accurate but also require less preparation time.
