1 Flexible plastic ruler, Length 160mm scaled in 5mm increments
Item #: D015-020-SD
i-KEYTM is a set of drill keys that provides precise guidance for sequential drilling during dental implant placement. The keys are compatible with all brands of surgical guide with regular platform (4.0mm sleeve opening), including the new EZ Stent® for fully guided step drilling. To prepare an osseous site, simply insert an i-KEYTM into the surgical guide to guide a drill with the corresponding size. Based on the preferred drilling sequence, successively larger drill keys and drills can be used to enlarge an implant site to the appropriate diameter.
i-KEYTM is made of surgical-grade stainless steel with a titanium coating and is fully autoclavable for infection control. The inner diameters are laser-marked on each drill key for easy identification. Each drill key can also be purchased separately so user can mix and match to meet individual needs.

1. Is EZ Stent compatible with all dental implant systems ?
EZ Stent is designed to provide point of entry, depth and angulation control for all implant systems. The titanium drill sleeve of EZ Stent (inner Ø 2.3mm) is compatible with the pilot drill of most dental implant systems. We also offer a high-quality Ø2.3mm surgical drill that can be used to substitute the pilot drill of any other brand. Our pilot surgical drills are sold separately.
2. Can I use EZ Stent with Cone Beam CT ?
The titanium drill sleeve of EZ Stent (L10.0mm or 6.0mm) can be used as a radiographic marker on Cone Beam CT to verify that the positioning and angulation of the template are appropriate prior to surgery. Unlike stainless steel, our titanium sleeve has no radiation scattering in the scan, so you get a precise image. (See Clinical Case #1).
3. Can EZ Stent be adjusted on the study model after CT scan verification?
If necessary, EZ Stent can be easily adjusted after X-ray or CT scan evaluation. Simply re-drill the hole in the same study model and secure the guide pin in a different angulation. Then soften the same stent again in hot water and mold it over the re-angled pin. The thermoplastic base of EZ Stent can be re-heated 2-3 times for minor adjustment on the model without deterioration.
4. How do you determine the drill depth with EZ Stent ?
The drill depth can be determined by measuring the distance from the top of the titanium sleeve to the intended base of the implant fixture on the pre-operative CT scan. (see sample image here)
5. Does EZ Stent provide drill depth control during surgery?
EZ Stent does provide precise drill depth control with our new silicone stoppers. Simply trim a silicone stopper to the appropriate length based on scan measurement, and insert it over the pilot drill. IMPORTANT: Make sure the stopper is seated all the way onto the handpiece head to prevent push-back during surgery.(see instruction of the drill stopper here)
6. Can EZ Stent be used for multiple implant placements ?
The EZ Stent Multiple Teeth Set can be used to fabricate a surgical guide for accurate multiple implant placements. (See Instructional Video here).
7. Can the EZ Stent be re-used ?
EZ Stent is intended for ONE TIME USE only. EZ Stent cannot be autoclaved, so re-using it can introduce cross-contamination between patients.
8. What if patient's jaw opening is limited, or the surgical site is towards the back of the mouth where access is difficult ?
The shorter titanium drill sleeve (L 6.0mm) of the Multiple Teeth Set is designed to accommodate patient with limited intra-oral access.
Alternatively, the surgeon can insert the surgical drill halfway into the metal sleeves before transferring the whole assembly into the mouth, so that the patient does not need to open as wide during EZ Stent insertion and usage.
9. Is the EZ Stent eligible for insurance reimbursement ?
EZ Stent could be eligible for dental insurance reimbursement under Procedure Code D6190 (radiographic/ surgical implant index).
10. How do I locate the drill hole in the model ?
We recommend securing the model on a survey table, then prepare the drill hole in the model using a drill press (available from any hardware store). Free-handed drilling using a straight nose cone handpiece can also be done.
11. Do I need to block out the undercuts on the model ?
Due to a slight flexibility of the thermoplastic base material, usually we do not need to block out the undercuts on the model. Simply apply a thin coating of Vaseline on the model prior to molding the stent.
12. How hot should the water be ?
In general, the hotter the water, the faster the stent will turn soft and clear. The water should be at least 140°F (60°C). Hotter water will not overheat the thermoplastic base. Tips: Use a hemostat to hold the metal sleeve and immerse the stent upside down in hot water. Always use a glass container because the thermoplastic material will stick to the plastic container when it is softened.
13. How do I sterilize the stent ?
We recommend using a cold disinfectant to soak the stent overnight prior to surgery. The stent CANNOT be autoclaved.
14. What is the shelf life for the EZ Stent ?
If stored in a cool dry place the EZ Stent has a 3 year shelf life.
