Lack of single tooth :
The molar teeth are the first teeth to open in the mouth and, unfortunately, it is usually the first toothpaste that is lost because most of the teeth are toothpaste in the posterior region. Tooth extraction occurs due to extensive caries or root canal treatment, or longitudinal fracture of the tooth. The molars are very important teeth to maintain the relationship between the jaws and maintain the arch form of the jaw. If a person loses his or her teeth, several things happen:
First, the teeth opposite the jaw opposite to the empty space moves and moves. (This is a hawkish tendency in the tooth) Second, the teeth on both sides of the empty space toward the drawn space also travel from the distal side of the mesilas, and one or two years after the tooth extraction, we will have fewer spaces that the insertion of the prosthesis or implant It's harder for us because space is becoming more difficult for us.
For example, if you want to put a fixed or implanted prosthesis, you need to make more teeth on the teeth to create the initial space, or if you want to put an implant, you should use a smaller diameter, which also causes the implant with a smaller diameter It can tolerate more occlusal pressure, which causes the implant to suffer from fatigue or fatigue, reduces the life of the implant and increases the grip on both sides of the implant, thereby increasing the chance of rotting around the implants along the teeth.
