With proper diagnosis and treatment, the pulp and tooth can be preserved and long-term esthetics and function restored in most cases of traumatized teeth. However, delayed reimplantation of debrided teeth or root fractures with multiple root fractures may be difficult to preserve. In such cases, prosthetic treatment using autografts, implants, or bridges is generally used. However, autografts require an appropriate donor, implants have a high risk of low occlusion, especially in younger patients, and bridges require the formation of abutment teeth in both adjacent teeth, which carries the risk of pulpal necrosis. In such cases, bonded bridges may solve these problems. However, the success rates of bonded bridges reported so far are lower than those of autografts, implants, and bridges, so proper knowledge of the selection of the indications, the design of the formation, the choice of materials, and bonding is essential. In this lecture, I will discuss the scientific basis and clinical points of adhesive bridges. ※This is a lecture from the 22nd World Congress of the International Society of Trauma Dentistry (WCDT2024), held July 12-15, 2024.
