Replacing a large molar with one dental implant or two?

Replacing a molar space with a dental implant or two? Mesial Distal width considerations?

Misch recommends (Measure from crestal bone to crestal bone)

  1. 7mm M-D place 4mm diameter implant
  2. 8-12mm place a 5mm implant
  3. 14mm place 2 implants of 4mm
  4. 15mm place 2 implants of 4mm and 5mm
  5. 16mm place 2 implants of 5mm

Can place 2 narrows in the spaces also. Two 3mm implants are also good for these cases

Misch recommends at 11-13 gain space to 14mm.  This is from older addition textbook verify??

If 2 placed in mandible then mesial implant is slightly to lingual and distal slightly to buccal.  Occlusal contacts are placed on buccal of distal implant and central fossa of mesial implant.
If 2 placed in maxilla then mesial is to buccal and and distal to palatal.  Occlusal contacts are placed on lingual of distal implant and central fossa of mesial implant.

Crown margin height above gingiva if esthetics allow.

Personally I find it kind of a PIA to place 2 at 14mm and prefer one and just adding something to the adjacent teeth and placing implant slightly deeper.
