Abstract

Objective To summarize the treatment options for congenital maxillary lateral incisor agenesis (MLIA). Methods Review the literature, summarize the current treatment options and advantages and disadvantages of various methods of MLIA, and analyze cases. Results When a patient′s occlusion and other conditions are suitable for space closure and canine substitution, closure of the gap is the recommended method, as it has good aesthetic results and leads to good periodontal health. However, when closure cannot be performed, a dental implant has a strong advantage compared with other restoration methods. When planning implants for MLIA patients, doctors should carefully select the correct surgery time and take care with the implant position to obtain good results. Conclusion In the choice of a treatment plan for MLIA, we need to use the concept of multidisciplinary combined treatment to obtain a more satisfactory treatment effect with regard to aesthetics and function.
