People Prefer 3D Printed Dentures, According to New Clinical Trial Dentures from Formlabs If you lose your teeth, whether heredity or poor dental hygiene is the culprit, typically the result is dentures. In a recent clinical trial, selected participants were asked to compare standard metal dentures with 3D printed denturesand while the results may be surprising to some, the 3D printing community will likely concur. The research trial had a group of people, all in their 60s, ...try out 3D printed dentures first, and then gave them conventional dentures to use. The study participants had to alternate between the two pairs of dentures over a month, and once the study was completed, the results showed that the majority of the participants liked the 3D printed pair better. The participants said that overall, they felt better when they were using the 3D printed dentures they could speak more easily when wearing them, and the 3D printed set was easier to clean. Laser 3D printing technology is used to create dentures, which is far more accurate and offers a more precise fit than pouring a mold into a set of dentures does. Additionally, it usually takes about 96 minutes to complete a traditional denture mold, which includes shaping the mouth and pouring the mold into it; on average, it only takes about 65 minutes to 3D print dentures.

Kolibree, a tech company focused on connected solutions in oral health, launched Ara, an AI-embedded electric toothbrush earlier this year. Deep learning algorithms are embedded directly inside the toothbrush on a low-power processor. Raw data from the sensors run through the processor, enabling the system to learn the user’s habits and refine accuracy the more it’s used. Ara is designed to know exactly where in the mouth the user is brushing, even when the toothbrush is not connected to the mobile app. Whether brushing online or offline, brushing data such as the frequency, duration, and brushed areas is captured in the toothbrush and automatically synced via Bluetooth Low Energy when the app is open, Kolibree noted.

Artificial tooth Researchers produced an artificial tooth whose microstructure mimicked that of a real tooth. The outer layers, corresponding to enamel, were hard and structurally complex. The outer layers contained glass nanoparticles and aluminium oxide plates were aligned perpendicular to the surface. After the outer layers hardened, a second suspension was poured. It contained no glass, and the plates were aligned horizontally to the surface of the tooth. These deeper layers were tougher, resembling dentine. The tooth was then cooked at 1,600 degrees to compact and harden the material a process known as sintering. The last step involved filling remaining pores with a synthetic monomer used in dentistry, which polymerizes after treatment.[2] Hardness and durability approximated that of both the enamel and dentine of a tooth.[3]
