Dr. S asks:
I have an edentulous case that I have treatment planed for 4 regular platform dental implants in the anterior mandible to support a fixed prosthesis. However the CBCT shows that there is a clear anterior loop that tracks up to 14mm anterior to the mental foramen. This leaves just enough room to place the 4 implants with the recommended 3-4mm interproximally. The problem is that if I allow 14mm each side then I will only have enough space to place 2 regular platform implants inter-foraminally rather than the 4 I intended. Is it crucial that I avoid the whole anterior loop? Or can I just allow say 8-10mm and then place the implant without risking paraesthesia? Does anyone have any experience with this?
