Dr. Doron kalman deliberately fractured 2 natural teeth because he was angry with me for becoming emotional in his office. As a result of the first proceedure he placed implants and cracked two teeth in the process and immediately placed an implant in after an extraction without letting the area heal first. He also placed the wrong sized healing cap on one of the implants. His assistant didn't know how to suction the blood saliva and materials from the surgery, which frightened me and angered kalman toward me. Subsequently, upon the second visit after performing a bone grafting(which failed) he took 2 dental instruments, twisted two teeth and fractured them.
