Reply To: No prep veneers

Hello Dr. Jain

My apologies for the late reply.  I did not see your response.  Thank you for your feedback.

Please see my answers below:

1. Any mock trial was done?

No mock trial was done.  I typically get a wax up done for my prepped cases, but given that this was a no-prep case, no wax up was needed

2. Pts canine were attrited, what could be the reason?

The patient suffers from GERD and grinds his teeth, but does not have sleep apnea.  For this reason, we provided him with a night guard (NTI) post-cementation and advised him to see his primary care physician to manage the GERD.

3. What material is this veneer?

The material is eMax

4. What was the Bonding Protocol?

I use VarioLink Esthetic cementation protocol.  I’ve attached the instructions for your perusal.

5. It would have been difficult to hold, so what was used to hold the veneer and what was the sequence used?

I always use Pic-n-Stic from Pulpdent to hold each veneer.  This makes handling much easier, especially for large cases.

6. Was this done on semi adjustable articulator?

Yes

7. How have you decided to increase by 20 percent, as wouldn’t it be in accordance to eminence slope, was it taken into consideration and how?

Initially, the patient wanted to have his lower anterior teeth incorporated into the design, however, he wanted no prep.  We determined this was not possible as there was not enough clearance due to the anterior coupling being tight.  We did not decide to increase the length by 20% from the start.  This was determined after the case was mounted.

8. What Post Cementation care was Advised to prevent fracture?

I put the patient into a FDA approved appliance call NTI (nociceptive trigeminal inhibitor)

9. Where is the location of junction of veneer onto teeth Palatally?

As these are no-prep then is no junction that rests ‘onto’ the teeth.  The finish line is at the junction where the natural tooth ends.

10. What occlusal guidance scheme was followed?

We did not alter the occlusal scheme.  It was bi-lateral balanced before we started.  The canines have worn down but typically I like to restore them with canine guidance.
