The virtual material used for each test was a bur to mark the point of impact, a cylindrical 2 mm drill-driver, a cylindrical 2.85 mm drill, a 3.5 mm drill, and a conical 3.5/4.7 mm drill.
These 21 patients, who underwent frontal cranial vault plasty, were reshaped by a burring down of the supraorbital ridge and the frontal bossing and a recontouring of the forehead through augmention with HAC (BoneSource; Stryker Leibinger GmbH, D-79111 Freiburg, Germany) during a 36 month period.
A bone trephine bur of external diameter 2 mm was used to obtained a bone core from the centers of socket preservation sites at the uncovering surgery (Fig. 3d).
Once a story is set in a wood, it sticks around like a bur or a strangling length of ivy.
b Using a bur or cutter, a portion of the guide was cut away so that the metal plate could fix the bony segments together.
By changing the FLH and the time to initiate transverse direction (TD) expansion, the relative number of lamellae stacked both perpendicular and parallel to the machine direction (MD) could be controlled for a constant blow up ratio (BUR) of 4 1.
Once the impact point is determined, the drilling of the implant was performed using a standard set of drills: a bur-haired and different cylindrical drill (2 mm, 3.2 mm, 3.7 mm, 4.2 mm, 4.7 mm, and 4.85 mm).

Mr. Ruckelshaus said he would hold the manu facturers to "a very strict bur den of proof" before granting extensions of the deadlines.
Ankylotic bone mass was removed using a fissure bur until a thin layer of bone remained on the most medial aspect of the bony union.
