I have treatment planned a patient to place a dental implant in #12 area. I have a Tomographic view of the site and there is adequate occlusogingival dimension to place an 11mm long implant in the site. However, there is only 5.8mm mesiodistal space between #11 and #13. I would like to place a 3.8mm wide implant there. That will leave me only 1mm of space on each side. Will this be enough space between the implant fixture and the adjacent natural teeth? If I do not place the 3.8mm wide implant, I will have to drop down to the next narrowest implant which is only 3.4mm. What should I do?
