A noiseless handpiece providing indicator lights. The head portion of the handpiece has one or more internal silencers for baffling the noise that is a byproduct of the generation of the rotational force used to drive the drill component. The indicator lights communicate one or more operational states to the user and reflect the engagement of an electrically connected transducer.

A lighting element is disclosed that provides a projection of light forming a substantially uniform bright light on a surface a known distance from the lighting element. The lighting elements includes a dome lens that is removably positioned on a light source, such that the light source is retained at a location within a focal length of a projection lens and at or within a focal length of the dome lens. The dome lens magnifies the light outputted by the light source, such that the projected light is brighter than the light generated by the light source.

A method for validating a preparation of at least one tooth in a prepared set of teeth for determining whether the prepared tooth is capable of accepting a dental restoration includes obtaining a virtual dental preparation guide configured for validating the preparation of the at least one tooth; obtaining a digital 3D representation of the prepared set of teeth; visualizing the virtual dental preparation guide together with the digital 3D representation of the prepared set of teeth; and validating from the visualization of the virtual dental preparation guide together with the digital 3D representation of the prepared set of teeth whether the prepared at least one tooth is shaped such that it can accept the dental restoration.

A splint device for guided robotic surgery, includes an arcuate splint body having first and second ends and opposing concave and convex surfaces. The splint body defines a plurality of holes spaced apart between the first and second ends, with each hole extending between the concave and convex surfaces. A tracking portion is engaged with the convex surface of the splint body between the first and second ends such that at least one of the holes is disposed between the tracking portion and each of the first and second ends. The tracking portion extends outwardly from the convex surface and has a kinematic mount engaged therewith.

A rolling bearing includes: an outer ring including an outer ring raceway surface on an inner peripheral surface; an inner ring including an inner ring raceway surface on an outer peripheral surface; a plurality of rolling elements rotatably arranged between the outer ring raceway surface and the inner ring raceway surface; and a sealing member fixed to a seal mounting groove formed on an axial end portion of the outer ring by a retaining ring, the sealing member sealing an axial end portion of a bearing internal space between the outer ring and the inner ring. The sealing member includes a protruding portion at a radial outer end portion, and an outer diameter of the sealing member is larger than an outer diameter of the retaining ring in the seal mounting groove.

The disclosure relates to methods for attaching a dental implant surgical guide and a dental implant to a dental surgical site including: assembling an implant combination, positioning the dental implant surgical guide including a double open-ended guide cylinder at the dental surgical site; rotating the implant combination through the double open-ended guide channel; and attaching a cap comprising a hollow cylinder to the double open-ended guide channel so the rim of the implant mount body is sandwiched between the dental surgical guide and the cap. The disclosure further relates to a dental prosthesis apparatus including: an abutment; a dental implant; a dental implant surgical guide including a first and a second double open-ended guide cylinder connected by a support bar; an implant mount including a rim; and a cap operable to engage the dental implant surgical guide and sandwich the rim between the cap and the dental implant surgical guide.

A guided dental implant shield having an implant connector piece where the implant is positioned and an inner shield where the implant connector piece is placed in such a way to grasp the implant, an outer shield with monolithic structure which moves by sliding on the inner shield and guides it at an angle inside the cavity opening to the jawbone, and which has an angled part at its lower end, and a cap which is positioned under the outer shield in such a way to isolate the implant inside the shields.

A method for validating a preparation of at least one tooth in a prepared set of teeth for determining whether the prepared tooth is capable of accepting a dental restoration includes obtaining a virtual dental preparation guide configured for validating the preparation of the at least one tooth; obtaining a digital 3D representation of the prepared set of teeth; visualizing the virtual dental preparation guide together with the digital 3D representation of the prepared set of teeth; and validating from the visualization of the virtual dental preparation guide together with the digital 3D representation of the prepared set of teeth whether the prepared at least one tooth is shaped such that it can accept the dental restoration.

A dental machining system for manufacturing a dental restoration, including: a dental tool machine which includes: a dental blank holder for holding one or more dental blanks relatively movable with respect to one or more dental tools; one or more driving units each for movably holding at least one dental tool for machining the dental blanks; a determination unit for determining the type of each dental blank; an adjustment device for allowing the user to adjust the machining time, a level of quality of the dental restoration, and a level of security of the dental restoration and dental tool against machining damage. The system further includes a control unit which executes a trained artificial intelligence algorithm adapted to generate process parameters for the machining.

A method of converting an air/water dental syringe of the type having a syringe body and an autoclavable dental tip and lacking illumination into a converted air/water dental syringe adapted to be used with a disposable dental tip different from the autoclavable dental tip and with illumination capabilities includes using a conversion kit having a retainer body and a self-contained module. The syringe body is attached to a proximal end of the retainer body through a proximal opening for providing air and water. A proximal end is inserted into a distal opening of the retainer body. The self-contained module includes a light-emitting diode (LED), a battery powering the LED, and a switch to turn the LED ON and OFF. Light emitted from the LED provides illumination through a light opening on an outer surface of the retainer body generally towards a distal end of the disposable dental tip.
