Sonendo‘s patented apparatus and methods for endodontic treatment use a high-pressure liquid jet to effectively clean teeth by detaching organic material from dentinal surfaces and tubules. The pressure wave generator creates cavitation in the liquid, ensuring thorough cleaning of the treatment region.

A recently granted patent (Publication Number: US11918432B2) describes an innovative apparatus designed for treating teeth. The apparatus includes an enclosure with a mounting surface that is positioned against a tooth surface over a treatment region, creating a chamber to be filled with liquid. A pressure wave generator, coupled with the enclosure, directs a coherent, collimated energy beam through the liquid, generating pressure waves that create cavitation to clean the treatment region effectively. The pressure wave generator features a liquid jet device with specific dimensions and pressure requirements to optimize the cleaning process.

The apparatus, as outlined in the patent claims, incorporates various features such as an orifice with specific transverse width and axial length, a liquid jet with defined energy flux and velocity ranges, and a pressure range for the liquid used to produce the jet. Additionally, the apparatus includes elements like a pump for pressurizing the liquid, a suction port for fluid removal, and a controller for operational control. The pressure waves generated by the apparatus cover a wide range of frequencies, including widespread acoustic noise, to enhance the cleaning process. The apparatus is designed to efficiently remove organic material from the tooth's treatment region, with the pressure waves having sufficient energy to detach the material from surrounding dentin when the substantially gas-free liquid is present. The inclusion of a fluid source for delivering gas-free liquid, along with a suction port for liquid removal, further enhances the apparatus's functionality for dental treatments.
