A method of surface treating a drill, the drill including a shaft extending along a central longitudinal axis from a proximal end to a distal end, the proximal end of the shaft including a shank adapted for connection to a rotary driver, the shaft further including, distal of the shank, a fluted section including at least one flute extending along the longitudinal length of the fluted section, the method including the steps of: acid etching at least a portion of the fluted section of the shaft in order to create a visible matted effect, subsequently electro-polishing at least the portion of the fluted section of the shaft in order to visibly reduce the matted effect and subsequently creating one or more visual marking within the portion of the fluted section of the shaft.

Dental drill surface treatment

A dental drill guiding system includes a drill guide including a hollow tube having an exterior surface and a guide sleeve including an internal surface defining a through bore configured to receive the hollow tube of the drill guide. The exterior surface of the hollow tube and guide sleeve's internal surface have complementary anti-rotation sections. The drill guide's hollow tube further includes at least one radially extending protrusion limited in the axial extent and formed by an increase in radius of the hollow tube in the apical direction and dimensioned for accommodation in at least one undercut of the guide sleeve, such that when at least one protrusion of the hollow tube is housed in at least one undercut of the guide sleeve the hollow tube is axially retained within the guide sleeve such that removal of the drill guide from the guide sleeve in the coronal direction is prevented.
