* Clinician may use the G-Stop as a vertical stop for free hand guided preparation without the C-Guide.
* Clinician may use a G-Stop size that would correspond with implant diameter and Drilling Protocol according to Versah IFU.

How is the Versah C-Guide System different from other guided surgery systems?
1. It’s keyless — the operator does not need to hold a separate key during surgery. The Vertical G-Stop® attaches directly onto the G4 Guided Densah® Bur, providing simplified functionality during use.
2. The C-shaped hole in the C-Guide sleeve allows more optimal irrigation flow to the site.
3. The Versah G-Stop attached to the G4 Guided Densah® Bur can be used as a vertical stop to help control vertical depth.
4. Traditional guided surgery systems rely on the drill press concept with significantly low tolerances between the guided drill and the guided sleeve diameter, allowing only for one pass in and out. This does not work with Osseodensification. The C-Guide® sleeve is designed to be slightly wider than the Vertical G-Stop®, allowing for the pumping action needed for the Densah® Bur operation. The buccal opening of the C-Guide® sleeve and the Vertical G-Stop® multiple slots allows for additional adequate irrigation.

What has changed with the new Versah® Guided Surgery System from the previous generation?
The new guided system has been simplified for efficient workflow by reducing the required pieces. The G4 Guided Densah® Bur does not require the addition of any plastic gauge. The G3 Vertical Stop snaps directly onto the G4 Densah Bur, eliminating the need for a Vertical Gauge. This design allows for easy snap on-off of the Vertical G-Stops
• A more precise fit between the Vertical G-Stops and the new G4 Guided Densah® Bur.
• Autoclavable, reusable metal G-Stop Keys
• Compatibility with most surgical implant handpieces.
• The ability to provide depth control ranging from 3mm up to 15mm when used as a vertical stop without the C-Guide® Sleeve.
• The ability to provide depth control from 2mm up to 14mm when used fully guided with the C-Guide® Sleeve in a surgical guide.
• Color-coded four diameter sizes, for easy differentiation between S, M, L, and XL, with Vertical G-Stops matching C-Guide® Sleeves.

Do I need to buy the full kit, or can I buy them individually?
The C-Guide® Sleeves, G3 Vertical G-Stops, and G4 Densah Burs can be ordered a la carte—just follow our workflow chart above (“Getting Started with Versah C-Guide System”). When purchasing Versah® Guided Surgery components for a specific case, we recommend following the implant diameter to ensure the right sizes required are received.

Are there special Densah® Burs for Versah Guided Surgery System?
Yes. The G4 Guided Densah Bur features a built-in notch which allows the Vertical G-Stop® to easily snap onto the Guided Densah® Bur. The proprietary Densah® Bur design that facilitates Osseodensification remains the same.

Can I print my own guide in-house, or use my own lab?
Your Versah C-Guide is compatible with many treatment planning and printing software. Just follow the steps below:
• Set up your software to produce the guide with a negative space/window that matches the C-Guide® Sleeve outer diameter.
• Create a buccal window to match the Versah C-Guide Sleeve opening
• Order the C-Guide and the matching G-Stop from Versah
Please find a Versah Certified Lab. Versah can help your lab become a Versah Certified Lab

Is the Versah C-Guide compatible with my CEREC Guide?
Yes. Versah’s Vertical G-Stops in sizes S, M, and L are compatible with CEREC S, M, and L holes. However, if you would also like to utilize the C-Guide® Sleeve, the Versah C-Guide S is compatible with CEREC M hole, and Versah C-Guide M is compatible with CEREC L hole

When using the full C-Guide System, do I have to factor in my calculation for the 1mm shelf in the bottom of the C-Guide Sleeve?
Yes. We recommend using the following formula to calculate the G-Stop® drilling depth you will need: Implant length + 1mm shelf in the C-Guide + offset = Versah G-Stop length (3, 5, 8, 10, 11.5, 13, 15mm). For example, if you are placing a 10mm implant, utilizing a guide with an offset of 2mm, and using the Versah C-Guide, your formula would be 10 (implant length) + 2 (offset) + 1 (internal built-in shelf in the C-Guide) = 13, so you would select the 13mm Vertical G-Stop.

How do I calculate the D2 distance with my CEREC system?
Doctors may calculate the D2 distance using a simple formula of desired osteotomy depth plus 7mm (C-Guide Sleeve height). This will allow the CEREC guide to rest at bone level. The G-Stop together with the C-Guide Sleeve will control the desired drilling depth for the osteotomy

Do I need to use a bone level guide?
Yes. To allow for the necessary irrigation to reach the bone, we strongly recommend the use of a bone level guide with flap reflection.

* The G-Stop Vertical Gauge, and the C-Guide Sleeve are single use only.
