Patient: Hello, Dr. Zhang! My mother still has roots on her right 3rd and 4th teeth, but no roots on her 5th, 6th and 7th teeth! She wants to do porcelain for all 5 teeth, but does she need a root implant for the 7th tooth? I would like to ask you how to treat this case, and how much does it cost? She only has a partial photo of the 4th tooth. These 5 teeth are on the upper right side! I have already had porcelain restorations before. The 2 porcelain surfaces were broken by biting on something hard. When I went to the hospital to remove it, I broke the root of the 7th tooth! I want to consult how much it costs and how long it takes to implant a root? Zhejiang University School of Medicine Second Hospital, Department of Stomatology Zhang Yanzhen: the cost of dental implants in 8000 to 10,000 a piece. The time between implantation and restoration is 4 to 6 months. Whether the implant can be implanted or not, it is necessary to take a film to understand the width, thickness and height of the alveolar bone in the implant area, as well as the direction of the blood vessels, nerves and sinus cavities in the area, and to understand the whole body situation. Therefore, it is necessary to go to the hospital for further examination.
