A dental drill and a method of surface treating a drill. The drill includes a shaft extending along a central longitudinal axis from a proximal end to a distal end. The proximal end of the shaft includes a shank adapted for connection to a rotary driver. The shaft further includes, distal of the shank, a fluted section including at least one flute extending along the longitudinal length of the fluted section. The method includes: 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.

The invention relates to a rotary instrument (1) for dental implantology or endodontics, comprising at least one proximal part (10) configured to be connected to a rotational drive means, and a distal part (20), the shape of which is determined by the use of the instrument; the instrument comprising flexible means that make the instrument (1) flexible.

In an aspect, a method of manufacturing a surgical kit includes providing one or more medical devices based on a three-dimensional (3D) image of an anatomical structure. The method additionally includes providing packaging based on the 3D image, and providing the surgical kit utilizing the packaging and the one or more medical devices. In another aspect, a surgical kit has one or more contoured packaging surface having a contour that matches a contour of an anatomical structure. The contoured packaging surface has one or more features for receiving one or more medical devices provided based on the contour in the 3D image. The surgical kit additionally has a lid connected under pressure with the one or more contoured packaging surface. The lid has apertures for sterilization of components of the one or more medical devices situated between the lid and the contoured packaging surface.
