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

Question

I was told ( as an option) that in order to avoid a sinus lift in tooth #3 the implant could be placed in an angle ( between #3 and #4( extracted) approximately at 45 degrees as shown in sketch below. Then the abutment would be placed in a vertical position. I'm concerned of the distribution of forces may place an angular momentum or torque on the implant. I was told the bone does not care. Does anybody see a problem with this? Does anyone have experience with this?

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.

Joseph F. DelPrete, DMD · Answer

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.
