Dear Dr. Manalili, 

We see so many implant cases being completed nowadays with immediate placement. Why was that method not adopted in your full-arch implant rehabilitation (Chairside® magazine, Vol. 17, Iss. 2)? 

DDS, Salt Lake City, Utah 


Dear Doctor, 

For complicated full-arch implant cases like this one, I always utilize Glidewell’s Digital Treatment Planning (DTP) team. Although they gave me the confidence and the resources I needed to immediately load this case, I decided to delay implant placement.

Immediate implant placement is a valuable treatment option, but dentists should never feel pressured to complete an immediate full-arch implant case unless they have the capacity to do so. It is also important to consider the well-being of the patient who may not be able to physically comply with the demands of a full-arch rehabilitation in one appointment.

The pressure to complete full-arch implant rehabilitations with immediate implant placement should never get in the way of what’s best for the patient and for the clinician. 

Dear Dr. Johnson, 

You mentioned two migraine prevention devices in your article: the NTI-tss Plus® and the NTI OmniSplint® (Chairside magazine, Vol. 17, Iss. 2). Which one should I prescribe in my practice?

Hello Doctor,

The NTI-tss Plus follows the original style of the first nociceptive trigeminal inhibition tension suppression system, which was created by Dr. Jim Boyd over 30 years ago. It is backed by decades of research that shows its efficacy in reducing tension-type headaches and migraines. The small, anterior style of the NTI-tss Plus is ideal for patients who struggle with gag reflex. I more commonly prescribe the device for the lower arch, unless the patient presents with an overbite greater than 50% or an overjet greater than 4 mm.

The NTI OmniSplint was created by Glidewell in 2021 and offers the same clinical success as its predecessor. It mimics the same anterior pointstop (the small resin nodule at the front of the device) but offers full occlusal coverage. Unlike the NTI-tss Plus, the NTI OmniSplint covers both arches. This style is ideal for patients who are used to wearing retainers or bite splints and for patients worried about aspirating a smaller device — though such concerns are unfounded.

Dear Dr. Park,

I was unable to attend the 2022 Glidewell Symposium that was highlighted in the previous issue of Chairside (Chairside magazine, Vol. 17, Iss. 2). Will there be more symposia at Glidewell in the future?

DDS, Tallahassee, Florida 


Hello Doctor, 

Glidewell Clinical Education will be hosting seven other Glidewell symposia in 2023 that you might be interested in. Each one offers a deep dive into some of the most topical themes of dentistry, including dental sleep medicine, esthetic dentistry, complete dentures, digital dentistry, and women’s leadership in digital expansions. I highly recommend these engaging learning opportunities that have the potential to fuel your success for years to come. Visit glidewellsymposium.com for more information or to register. Tickets sell out quickly! 

See you there, 

Neil Park, DMD
