Back molar teeth can have immediate implants! This means that the same day a molar is extracted, an implant can be put in the socket. When it is possible, this saves you money by avoiding the cost of a second procedure or bone graft. Besides cost, it also saves you time because you don’t have to “extract, then let it heal for 2-4 months.” You want your tooth as soon as possible!
In order to do an immediate implant for a back molar tooth a large, wide diameter implant must be used.
Super Wide Diameter Implants (6.0mm and larger)
-reduces or eliminates the need for bone grafting in back tooth extraction sites
-enables proper emergence contour of the final crown 
-reduces stress delivered to the implant-bone interface as well as throughout the rest of the implant
-Ideal for “rescuing” teeth implants where smaller-diameter implants have failed
Less invasive
-Shorter treatment time
-Prevents bone shrinkage.
-Following an extraction, bone width decreases 25%-40% in the first year!
Considerations
-Size of tooth being replaced. The average measurements of back teeth indicate use of a 7.0mm implant. Tooth size varies by type of tooth as well as your genetics
-Nerve position is critical
Increased initial stability (tightness when first placed)
-When the diameter of the root is less than that of the implant, the resulting primary stability is greater. This is important for the
