Publication number: 20240350228Abstract: A frame for a dental dam, a kit comprising the frame, and a method of accessing a patient's oral cavity during a dental procedure using the frame. A body of the frame defining two portions engaging with the dental dam at opposite sides of the body. The body is conformationally adaptable between an open configuration, where the two portions are splayed away from each other in the open configuration to spread out the dental dam, and a retracted configuration, where the two portions are drawn towards each other to fold the dental dam. The kit may have a device comprising a member suitable for biting on and elongated between an intraoral end and an extraoral end, an intraoral fitting at the intraoral end, and an aiming portion at the extraoral end that is positioned complementarily to the intraoral fitting about the member to facilitate extraoral targeting of the intraoral fitting.Type: ApplicationFiled: September 1, 2022Publication date: October 24, 2024Applicant: PDS Inc.Inventors: Mahmoud TORABINEJAD, Mason A.

Publication number: 20230034006Abstract: A dental tool electrically powered by a power source includes: a handpiece having at least one switch; and a probe attachable to the handpiece so as to define a probe tip, the dental tool being operable to maintain the probe at its probe tip at a specifiable temperature. At least one of the handpiece and the probe includes a thermoelectric device, the dental tool being operable to maintain the probe at said probe tip at a specifiable temperature in response to user actuation of the at least one switch. Optionally, a second handpiece having an electrically conductive enclosure houses a second switch held by the patient. A method of conducting a dental test on a tooth of the patient includes: generating a sensory stimulus at the probe tip when the probe tip is in contact with the tooth; and receiving an actuation by the patient of the second switch.Type: ApplicationFiled: December 4, 2020Publication date: February 2, 2023Applicant: PDS Inc.Inventors: Mahmoud Torabinejad, Mason A.

Publication number: 20200000549Abstract: Dental surgical stents can be used to assist a dental surgeon. A hard tissue stent can include an access hole formed in one side and may be placed over one or more of the patient's teeth where the access hole is accurately aligned at a location for drilling to, for example, remove infection. Suction channels may be included in the stent to provide suction about the access hole to remove saliva, water, bone debris and the like, during the surgical procedure. A soft tissue stent may be placed over one or more of the patient's teeth, where the stent can include a mark positioned where the surgeon is to cut to create an access flap in the soft tissue. By keeping the flap attached to the semi-circular window of the soft tissue stent, the surgeon can more easily return the flap to the proper position.Type: ApplicationFiled: June 29, 2018Publication date: January 2, 2020Applicant: CORNERSTONE SPECIALTY PRODUCTS, LLCInventors: Hamid Reza ABEDI, Ajay KUMAR, Mahmoud TORABINEJAD, Arin ALEXANDER
