A dental drill has a main body and a collecting hood. The main body has a first cutting member and a second cutting member, and both of the first cutting member and the second cutting member have a blade on two sides. A drill is formed by the first cutting member and the second cutting member with their respective bottom ends, a top end of the drill connected to a drill shank. The collecting hood has a closed end and a circular wall forming an accepting space in the collecting hood. The closed end having an engaging hole accepting the drill shank, and, a bottom inner face of the closed end has four clefts arranged in a cross shape and four pairs of the scrapers with a scraping section inbetween.

The present disclosure provides a dental screw (10) for fixing dental components (1, 2) to each other, the dental screw having a proximal end (11), a distal end (12), and a longitudinal axis (LS), wherein the dental screw further comprises a screw head (13) including a tool engaging interface (20) for engaging a fastening tool (30) at the proximal end and distally to the screw head a screw shank (14), the screw shank comprising a torque limiting portion (15) and distally to the torque limiting portion a threaded portion (16) for engaging a dental component (1, 2, 3), wherein the dental screw is configured to transfer a minimum torque from the tool engaging interface to the threaded portion of 26 Ncm and the torque limiting portion is configured to limit the torque transferable to a maximum torque for preventing damage to the threaded portion. The disclosure also provides a dental fastening tool, a dental fastening set, and a dental support set.

Dental prosthetic screw, tightening tool and coupling system firstly refers to a screw for retaining and fixing a dental element in a dental implant, said dental element being able to be any component that preferably aims to support a dental structure or dental prosthesis, preferably machined or laser sintered or laser sintered and re-machined or machined by CAD/CAM, and even the structure itself or dental prosthesis. Therefore, different components are used in the manufacture of prostheses on dental implants in human implantology, requiring said components to be retained and fixed to the dental implant by means of screws on the implant. Moreover, the invention relates to a screwdriver or tightening tool compatible with said dental screw and a tightening or coupling system formed by the two.

A depth stop for a drilling tool to form a hole of predetermined depth. The depth stop includes an interface portion that couples directly to the shank of the osteotome via interlocking spur and groove features. The interface has a cap flange and a tapered skirt. The underside of the cap flange establishes a reference surface for a tubular key that slides onto the tapered skirt and is held there by friction. The skirt is formed with a relief directly under the cap flange to facilitate haptic confirmation of proper connection. Elongated irrigation windows in the key expose a domed transition on the osteotome, thereby facilitating irrigation. The depth stop can be used, optionally, with an alignment jig designed with a precision guide bushing. The guide bushing is semi-cylindrical and terminates with an internal abutment step against which the lower end of the key engages at full depth.

A medical or dental device for determining a bone's quality by cutting a thread into the bone with a rotating threaded element comprises a control unit having a measurement circuit configured: (i) to determine values of the motor current via a first electrical contact device with which the motor drive is supplied for rotational drive of the threaded element that can be connected to the motor drive, the current values being a measure of the bone's quality; (ii) to monitor and/or to determine the penetration depth of the threaded element into the bone, and (iii) to generate measurement signals which show the relationship between the penetration depth and the determined current values or parameters derived therefrom, and to transmit these signals to a display unit, which displays the relationship between the determined current values or parameters derived therefrom, in particular the bone's quality, and the penetration depth.

The surgical guide tool for single dental implant positioning includes an adjustable U-shaped frame having an inner member and an outer member. The inner member of the frame includes a first arm and a second arm that extends normal to the first arm. The outer member of the frame includes a first arm and a second arm that extends normal to the first arm. The first arm of the outer member includes an inner cavity for slidably receiving the first arm of the inner member. The first arm of the inner member can be moved within the cavity to adjust the size of the frame. A ring, attached to the second arm of the inner member, includes a circular wall with a central aperture extending therethrough. The central aperture is configured for receiving a drill bit therethrough for properly positioning the drill bit on the jawbone.

A dental surgical retraction article is manufactured by combining one or more aliphatic or cycloaliphatic isocyanates with one or more polyols including at least one polyether polyol that has a molecular weight of at least 2000.

A surgical incision device for dental implant placement is provided. The device comprises of two parallel blades, one perpendicular blade, skateboard-like surface and two finger rests. Said two parallel blades are half-elliptical in shape and parallel to each other. Said third blade is half round in shape and perpendicular to other two blades. All three blades are attached to a single skateboard like surface. Said two finger rests positioned opposite to each other on skateboard like surface with one designed for index finger and the other for thumb. The device is capable of producing a double papilla sparing incision. The device further comprises of two-wheel like blades, center of rotation and protective cap.
