Dr. K. asks:
I read in Dental Economics where Gordon Christensen has proposed using mini dental implants to help support fixed bridges. You place the mini implant in the pontic region and then you connect the metal framework to the mini dental implant and natural teeth. In the case he described, the natural teeth, which will serve as the abutments, were not ideal and were to some extent questionable. BY using the mini implant and the natural teeth together as abutments, he felt this design would suffice for this particular case.
In order to prevent the natural teeth from intruding, he recommended using resin cement and roughening up the surface of the axial walls to increase retention.
Has anybody tried this technique? What are your thoughts?
