Teeth that have undergone trauma are best observed for 3-6 months or more before permanent treatment. Because of the uncertainty of the long-term results of traumatized teeth, internal resorption or external root resorption may occur. Teeth with mesial root fractures can only be extracted. Teeth with only a crown fracture and exposed pulp can be retained if they are not too loose and the root length is normal, requiring root canal treatment first. When choosing a restoration method, if both adjacent teeth in the anterior area are root canal treated teeth, a fixed bridge restoration is preferred. It can be a metal porcelain or a high-strength all-ceramic bridge such as zirconia porcelain. The specific materials can be found in the answer to the patient’s question I wrote. If the adjacent teeth are healthy, dental implants are the best. Although expensive, but the use of long years, now the survival rate of the regular system of the famous hospital can reach 95% or more. The diagnosis after the examination of the physician is still the best.
