The accuracy of implant placement is determined by the first drill.
DIOnavi. Surgical Kit is equipped with the drill tube system, unique to DIOnavi. that plays a crucial role for the highest precision of the first drill.
The drill tube maximizes contact area with the drill, which helps to firmly hold the horizontal path when drilling.
In particular, because the drill tube is longer than usual, increasing vertical guidance of the drill, it results in increased accuracy and stability while drilling.
The 9mm drill is guided by a 7mm drill tube, and a longer, 12mm tube is provided to be used in the anterior, where even higher precision is required.
Besides length, the drill tube in DIOnavi. Surgical Kit is designed to be inserted into the punched soft tissue. When drilling, the drill tube is first inserted into the drill and seated on the guide. It is praised for its differentiated excellence in all aspects of accuracy and convenience in limitation of space within the oral cavity.

In addition, all of Korea's precision processing technologies have been concentrated to eliminate errors in drill tubes.
The tolerance between the drill tube and the guide is 0.01 mm.
This is the minimum tolerance value that can be narrowed with Korean processing technology.
The result of the study that the tolerance of 0.01mm between the drill tube and the guide arithmetically shows an error range of less than 1 degree (DIOnavi.’s average degree error is 0.4 degrees),
while showing a 5 degree error when drilling without using a drill tube is presented other studies.

'DIOnavi. Surgical Kit' is a system that completely solves concerns about bone heating. 'DIOnavi. Surgical Kit' is a guide kit consisting of a precision machined drill from 'Maillefer' in Switzerland. Unlike the conventional high-speed drilling system, low-speed drilling without irrigation at 100 rpm is required owing to the excellent cutting force and durability of the ‘DIOnavi.’ drill. On average, 'Drilling Time' is completed within 10 seconds during implant surgery. As a result of 'Heating Test' during that period, 'DIOnavi. Surgical Kit' showed around 39°C, a very low value compared with conventional high-speed drilling. In addition, DIOnavi. provides an easy safety system that injects saline with a 'metal needle' for each drilling section, removing particles in the bone cavity, and cools down into the deepest area of the osteotomy, and at the same time, a sort of guided irrigation system used to safely and easily avoid bone heating.
