  • Publication number: 20230034006
    Abstract: 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.

  • Publication number: 20200000549
    Abstract: 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.
