The "SIG" Device is a multi-functional prefabricated surgical stent to assist with the accurate placement of IMTEC’s Sendax Mini-Dental Implants. It's main use is in edentulous jaws to obtain overdenture retention with MDI's and metal housings. The SIG Device features one piece construction, a terminal titanium metal sleeve to allow for the 1.1mm Pilot Drill to pass through, a horizontal floss hole 5mm away and an O-Ball Head Recess 10mm from the drill hole, just in front of the finger grip. The finger grip handle extends backwards for stability and has a concavity on its underside to pass over additional exposed O-Ball Heads. The body of the SIG Device has serrated edges to prevent slippage on gingival tissues. It is made of a hard, clear plastic that can be re-sterilized for multiple uses.

The SIG Device is easy to master and use. It will give the operator confidence since it will allow him to obtain proper site selection, insure limited depth penetration into bone by the Pilot Drill and be perpendicular to the bone ridge. The SIG Device will keep the MDI's 10mm apart to allow room for metal housings in the denture intaglio and insure parallelism of the fixtures placed in the jaw. The most significant achievement is that when the SIG Device is used properly, it will place the inserted MDI fixtures at a safe distance from the mental foramina, thereby removing the risk of any lip paresthesia. The low cost and simplicity of design makes the SIG Device a welcome addition to the MDI surgical kit.
