Can dental implants be put in sideways?

My implant was putting on an angle and it left me in pain every time I tried to chew. In my previous post, you will see photographs of the angle the implant was on. When I went back to the physician, he said that he couldn’t get his tools into my mouth. I had a good angle…. is there any excuse for putting it in sideways? Eventually, it caused me problems not just not being able to eat on it. The crown was put in on top of it and as you can see on the photographs you can’t you like that
