I have a patient that I am placing an implant on #19. He is missing #18 and #20 has class II mobility due to trauma from occlusion. I would like to place #19 with possibly having to place an implant on #20 in the future in mind. I know the minimum distance from an adjacent tooth is 1.5-2mm and distance away from an implant is 3mm. However, what would you say the furthest I should place #19 away from #20 is?

Made a quick little diagram for ya. Does this help? You’re right that you should not place it within 2mm from #20. Besides that you need to consider the Mesio-Distal length of #20.
SInce the average MD length of a mandibular molar is 10mm, the furthest you’d want to start your prep is 5mm away from #20. As shown in diagram. LMK if that helps or if you have more questions about it 🙂

That being said I would still place it less than 5 or countersink it two mm so I had papilla formation. Nothing sucks more than a black triangle at the finish line.
