2. Drilling
A pilot hole is drilled in the patient’s dental model, using an Analogue Drill (DB10-0035 or DB10-0036) in either a straight or contra-angle dental hand piece, or in a laboratory hand piece (DB10-0037), to a depth of approximately 10 mm. It is critical that the drill is held at the correct 3D angulations to ensure that the desired vertical and mesio-distal insertion angles are produced. This procedure is normally performed ‘free hand’, but if desired, a technician may use the Analogue Drill in a vertical pillar drill with the model set on an adjustable angled table (as described in Cousley RRJ, Parberry DJ. Surgical stents for accurate miniscrew insertion. Journal of Clinical Orthodontics 2006; 40: 412-417).
