The present invention discloses a negative-pressure oral apparatus capable of relieving discomfort of soft tissues in the oral cavity and improving fixation of the oral apparatus to prevent the oral apparatus from falling off due to mouth opening. The oral apparatus is compact and elastic so that it fits various shapes and sizes of the oral cavity and is easy to be put on and taken off to provide convenience and safety to the user. In another embodiment, a method for maintaining a negative oral pressure and collecting liquid by coupling the oral apparatus to a liquid collecting apparatus capable of effectively providing the oral cavity with a negative pressure to expel liquid in the oral apparatus and deliver the liquid to an absorbing element in the liquid collecting apparatus so as to prevent liquid leakage or contamination.

A disposable saliva ejector that utilizes a single planar, double leaf shaped plate design that is embossed on their inner faces with a series of arced ribs and folded about its midpoint. A tab and slot arrangement about the center of the plates, joins the two plates. The distal tips are held together by a dovetail arrangement on raised pads at the distal tips of each plate. The distal and proximal tips are also held in operational contact by the suction forces passed through the device. The arced ribs form a series of channels about perimeter of the device. A trough runs along the linear axis of both of the plates to direct any fluid and debris that is sucked into the channels into a connected suction tube. Placement of the saliva ejector within the mouth lies along the interior of the patient's cheek, keeping the oral cavity clear of viewing obstructions. The discharge end connects to a discharge tube, wrapping around the oral commissure then hooking onto the patient's outer cheek. Once properly placed within the patient's mouth the dental assistant is relieved from providing suction during various procedures.

A dental valve device having a disposable turret is disclosed having a valve body having a tip receiving end, a hose receiving end, a lumen formed between the tip receiving end and the hose receiving end, an opening formed in the valve body, and a rotatable valve sealing body adapted to being inserted into the opening, the rotatable valve sealing body having a bore for alignment with the lumen formed between the tip receiving end and the hose receiving end, the bore having a tip receiving end opening and a hose receiving end opening, the rotatable valve sealing body having an outer surface having an indentation formed in the outer surface adjacent to the tip receiving end opening with the indentation having an upper ramp portion, a lower ramp portion, and an end having a tab portion.

An optical fiber coupling system may include a first coupler half fixed to a first fiber optic element. The first coupler half may include a first magnetically energetic material. The first magnetically energetic material may include a first aperture extending through the first magnetically energetic material. The first fiber optic element may extend within the first aperture. The optical fiber coupling system may include a second coupler half fixed to a second fiber optic element. The second coupler half may include a second magnetically energetic material. The second magnetically energetic material may include a second aperture extending through the second magnetically energetic material. The second fiber optic element may extend within the second aperture. When the first magnetically energetic material is proximate the second magnetically energetic material, the first fiber optic element may be longitudinally aligned with the second fiber optic element. An optical fiber coupler may include a coupler half fixed to a fiber optic element. The coupler half may include a magnetically energetic material. The magnetically energetic material includes an aperture extending through the magnetically energetic material. The fiber optic element may extend within the aperture. The optical fiber coupler may include a circumferentially extending material, at least partially around a perimeter of the magnetically energetic material. The circumferentially extending material may define a receptacle.

A dental tool system a shell made of silicone having a hollow interior and an opening to allow placement of the dental tool around a tooth, a tool base disposed along the hollow interior of the shell, an interchangeable tool head supported by the tool base to hold a dental instrument to operate on the tooth, a flexible mirror disposed along the circumference of the hollow interior at a first angle from the interchangeable tool head to view progression of the dental instrument operating on the tooth, a spray supported by the tool base and positioned adjacent to the interchangeable tool head, a suction supported by the tool base and positioned adjacent to the opening of the hollow interior to allow suction of fluid around the tooth, one or more camera to capture an image of the tooth, and a controller configured to move the interchangeable tool head.

The invention relates to a device which is inserted into the mouth so as to isolate the dental part or area of the mouth to be treated, allowing improved vision, preventing the cheek and the tongue from impinging on the working area, and protecting the tissues of the patient from the dental instruments. Furthermore, the sucking capacity of the device prevents the saliva or any other fluid generated during the treatment from affecting both vision and the performance of a correct technique for carrying out the dental treatment.

A dental device and method for use in the dental device are disclosed. The dental device includes a frame with an interior tube, at least one aperture extending from an exterior surface of the frame into the interior tube, and a mesh material coupled to an interior surface of the frame. A method of using the dental device is also disclosed.
