What do you think of an implant being placed at a 45 degree angle? (Photo)

I would suggest that if you are spending the time, money  and effort to have implants placed and restored you should consider doing it in the most ideal fashion. Short cutting and not having a sinus lift creates potential restorative problems down the road. Additional cost and time up front will save you much heart ache if the implant fractures or the crown is continuously coming loose do to chewing forces that are being placed on the implant in a less than ideal fashion.

I would prefer placing the implant in the proper position rather than placing it at a 45 degree angle.  The biting force could potentially cause a failure of the implant.
