Diagnostic T
The Diagnostic T was developed as an analytic aid and is used for the initial diagnostic work up to assist the surgeon and dentist in determining minimum special prerequisites. The diagnostic T maybe used on study models or introrally to evaluate spatial relationships between teeth, and teeth and possible implants. The T can help to evaluate four different space requirements. The back side of the T shows the minimum height requirement to accommodate all surgical instruments during the surgical procedure. The front side has three possible measurements. Pictograms on the instrument show which arm of the T is used for which measurement. The X axis indicates the minimum occlusal space requirement for the lowest prosthetic restoration variant. Minimum interproximal distance between teeth (edentulous area) is determined with the Y axis indicator for all three platform diameters (3.5, 4.8, 6.5mm) and the Z axis indicator illustrates the minimum distance requirement from the center of the proposed implant to the adjacent tooth.

Implant Distance Indicator
The discs at the ends of the arms of the Implant Distance Indicator correspond to the shoulder diameters of the different Straumann® platform diameters. The instrument can be used to check the available space before the start of treatment, or can be used during surgery to mark the desired site of implantation. Two of the discs on the distance indicator have a diameter of 4.8 mm in order to define the precise placement of several regular neck (RN) implants in a row. Depending on the precise positioning of the disc(s) at the planned implant site, it is possible to drill through the perforation in the disc(s) with a Ø 1.4 mm round drill in order to mark the center of the proposed implant on the crest of the bony ridge.

A adapter engages the hex at the top of the fixture mount to facilitate touch less pick up from the implant packaging and delivery to the osteotomy site. There are 2 adapter versions, each in 3 different lengths. The implant  can optionally be inserted manually with a ratchet or with a handpiece and each delivery method requires a dedicated adapter.

Holding key
When loosening the fixture mount from the implant, the holding key (catalog # 046.064) is used to engage the secondary hex closest to the implant for stabilization (counter torque) and the fixture mount is loosened with the ratchet or handpiece (counter-clockwise) only. The shape of the holding key is specially designed for different oral situations. The forked end when mesio-distal spaces are normal and the closed end when the interdental space is limited.

The ratchet (Fig.1 top, catalog #046.119) itself has no torque control mechanism. A torque direction selector at the end of the ratchet can be turned 180 ° to change the direction of the torque only. A secondary component called a "Torque control device" is coupled to the ratchet to form a complete torque wrench.
Torque device
The torque control device (Fig.1 bottom, catalog # 046.049) once coupled to the ratchet transforms the ratchet in to a complete torque wrench. A spring pin attached to the torque device is pushed away from the main body of the device until the desired torque value is reached. A torque value indicator welded at 90 ° in relation to the spring pin is marked at 10, 20 and 30Ncm.

SCS screw drivers are produced in three lengths (15, 21, 27mm) for the Straumann® ratchet. Latch type SCS drivers (Fig.2, middle)for a handpiece are available in three lengths (20, 26, 32mm) as well. Regular neck (RN) solid abutments are delivered with a dedicated abutment driver (Fig.2, right) offered in two lengths (13, 19mm). Solid abutment drivers can only be utilized with a Straumann® ratchet.
