message board A Fabulous Demonstration Why You Need a CBCT Every Time! A Townie shares a case in which taking an additional scan saved him and his patient from a world of hurt drwillie Member Since: 10/14/02 Post: 1 of 120 I'm doing this case tomorrow. Looking at the panoramic image, it looks like I have close to 20mm from the top of the ridge to the nerve. The coronal view says otherwise. This is an OCO Biomedical 4x10mm implant. And I had a 14mm implant I've been trying to use. ■ 2/26/2019 Fayad 2012 You are right there! I hate lower second molars. ■ Member Since: 03/29/14 Post: 2 of 120 2/26/2019 jmjennings Member Since: 06/09/08 Post: 3 of 120 Did you trace the nerve on your CBCT? I don't think what you see at the apex of your planned implant is the nerve. Looks like a void in the grafted site. The nerve is much more apical, I think. ■ 2/26/2019 washmodoc Member Since: 12/22/04 Post: 5 of 120 Is he worried about the nerve, or just pointing out he could have perfed through the lingual if he used a longer implant? That's how I read what he was saying. The nerve is clearly way gingival to the implant. ■ 2/26/2019 almunk Member Since: 12/17/05 Post: 7 of 120 I've never placed longer than 8mm implant in lower molar site. This keeps me out of trouble most of the time. ■ 2/26/2019 drwillie Member Since: 10/14/02 Post: 8 of 120 32 I should have been more clear. I don't want to perf the lingual concavity. I didn't trace the nerve, because it's so obviously very low, visible in the panoramic view. And, yeah, you can palpate the concavity but when millimeters count, I feel much better having the CBCT.
