I’ll preface this by saying I’ve only done a handful of implant cases. I have a patient whom I have treatment planned for an implant retained mandibular overdenture following the extraction of his remaining lower teeth. Should I use 2 or 4 implants? I understand immediate insertion of the implants is an option but not having done this before do you think this is an ‘easier’ case to start with. The other option is to do it in a delayed approach. So basically, should I extract the teeth and let the bone heal and install the implants later? Should I place bone grafts and membrane after extractions to preserve bone levels? I have only done a few implant cases and I would appreciate advice before proceeding.
