Pulp diseases and periapical diseases developed from caries can cause large area of tooth defects, and root canal treatment is the most effective treatment for them. The loss of tooth tissue during treatment will lead to the reduction of tooth flexural strength, which will affect the long-term repair effect. The posterior tooth is the most frequent tooth position for root canal treatment, and the repair method after the posterior tooth root canal treatment is the focus of clinical attention.With the development of repair technology and materials, and the popularity of minimally invasive concept, onlays have been widely used in the restoration of posterior tooth defects. In this paper, the materials and design methods of onlay restoration are discussed in order to provide reference for clinical work.
