Overview:
Versah® Guided surgery is an innovative system that allows for adequate irrigation, proper visualization of the osteotomy expansion/preparation, freedom to luxate the Densah® Bur and the ability to manage multiple sites with different preparation depths and diameters with precision.
Step 1:
Imaging: Obtain a CBCT scan and clinical impressions of patients designated jaw(s).
Step 2:
Treatment Planning: Contact Versah® certified dental lab. Send the lab the CBCT scan and clinical impressions. For a list of all Versah certified labs please visit:
Step 3:
Schedule case planning session with your lab to decide the final implant diameter, angulation, C-Guide® Sleeve placement, and drilling sequence with the needed Densah® Burs.
Maximum distance between the C-Guide® Sleeve and crestal bone level is 2 mm plus 1 mm C-Guide® Sleeve shoulder = 3 mm offset
Step 4:
Select the appropriate G-Stop® assembly. Snap the vertical gauge onto the Densah® Bur designated groove. The gauge should spin freely. (figure 1, 2, 3)
Example:
Large (L) G-Stop ® Vertical Gauge, (L) G-Stop® Key, (L) C-Guide® Sleeve

Step 5:
Follow the suggested Densah® Bur Implant System Drilling Protocol. Use the G-Stop® Keys in incremental steps, e.g., when the distance between sleeve and bone is 2 mm (see Step 3) start with the G-Stop® Key (5 mm) to mark your osteotomy and establish initial trajectory - Exchange (5 mm) for the (10 mm), repeat in regular intervals leading up to your final length, repeat with each Densah® Bur. Your G-Stop® Key must align with your C-Guide®.
Example (Final length desired 13 mm):
• Tapered Pilot Drill with (5 mm key then 10 mm, 13 mm)
• VT1525 with (5 mm key then 10 mm, 13 mm)
• VT2535 with (5 mm key then 10 mm, 13 mm)

*Clinician judgement and experience should be applied in conjunction with this clinical practice suggestive use protocol.
