Precision Marking Tip, Straight, Scale 8/10/13/16 mm | Helmut Zepf No. 47.990.08
The Precision Marking Tip, Straight is a component of the VGO Ost-Set osteotome system, developed by Dr. Pavel Krastev DDS as part of the patented VGO Ost-Set system (U.S. Patent No. 9,333,058 B1). It provides accurate purchase-point marking prior to osteotomy in immediate-placement implant surgery.
Product Overview
Rotary drills commonly slide down the bone surface due to the angle at which an osteotomy is initiated. The Precision Marking Tip is used during immediate placement surgery to establish an offset purchase point toward the palatal aspect before the osteotomy is started, giving the clinician a controlled, repeatable starting position.
