    Abstract: Dental instrumentation (180A, 180B) for use in guiding a cutting tool (210) to remove tooth structure from a working tooth (190A) is prepared. A digital model of cutting guide shell structure (162) for placement around a portion of the tooth to be treated is combined with preset tool movements to be made by the cutting tool by one or more processors to define final cutting guide data corresponding to final cutting guide structure (165) for guiding the cutting tool. A digital model of a fixation instrument configuration (168) for fixing the dental instrumentation to an adjacent tooth to the working tooth is combined with the final cutting guide data by one or more processors to define final instrument configuration data corresponding to a final instrument configuration (170) for releasably fixing the dental instrumentation to the adjacent tooth (169) and for guiding the cutting tool in the removal of the tooth structure from the tooth to be treated.

    Abstract: A dental drill system is provided, comprising a drill having a drilling part with a first end configured for drilling a hole in a jaw bone and a shank part with a second end configured for connection to a drill-rotating device and a guiding sleeve for guiding the drill. The guiding sleeve has a first side facing the drill-rotating device and a second side intended to face the jaw bone during a drilling operation. A guiding through-hole extends from the first side to the second side. A rim also extends at least partly around the circumference of the drill, and the system comprises a drill stop sleeve provided with a recess extending circumferentially around an inner side of the drill stop sleeve, allowing the drill stop sleeve to be snap-locked onto the drill. The guiding sleeve also comprises a flange that defines an end position for the drill stop sleeve.

    Abstract: A surgical template (10) comprises at least one a drill guide bore (70) surrounded by a guide bore ring (71) and is adapted to be positioned within the oral cavity of patient. The template (10) comprises an inner rail (20) and an outer rail (30) with an interspace (60) in between. At least three inner and three outer connecting points (81, 82) are provided on the inner and outer rail (20, 30) which are adapted to be positioned on portions of the dental apparatus of the patient in his oral cavity to define the three dimensional position and orientation of the at least one drill guide bore ring (71). The rails (20 and 30) are provided in a predetermined varying distance one from the other allowing accommodation of the inner and outer connecting points (81 and 82) on the rails (20, 30), wherein the template (10) further comprises at least two connecting webs (40) connecting the inner rail (20) and the outer rail (30) in a predetermined distance one from the other.

    Abstract: The invention concerns a dental surgery device (1), comprising a punching member (15) having a cutting end part (16) suitable for removal of tissue on a jaw bone of a patient, and a guiding sleeve (7) for guiding the punching member (15) during a punching operation. The guiding sleeve (7) has a first side (8) intended to face away from the jaw bone and a second side (9) intended to face towards the jaw bone during a punching operation, and a guiding through-hole (101) extends from the first side (8) to the second side (9). The punching member (15) is adapted to fit into the guiding through-hole (101) such as to allow guidance by the guiding sleeve (7) when the punching member (15) is moved in an axial direction through the guiding through-hole (101). The invention is characterized in that the punching member (15) and the guiding sleeve (7) are provided with complementary guiding means configured to control the axial movement of the punching member (15) through the guiding through-hole (101) during the punching operation, wherein the complementary guiding means comprise at least one guiding element (17) that extends in a radial direction and at least one guiding groove (18) adapted to receive the guiding element (17) and guide its movement along the guiding groove (18), wherein the guiding groove (18) extends both in a circumferential direction as well as in an axial direction such that, when the guiding element (17) and the guiding groove (18) are engaged, a rotation of the punching member (15) in relation to the guiding sleeve (7) forces the punching member (15) to move in relation to the guiding sleeve (7) in the axial direction thereof.
