Talking about the inlay repair technology of contemporary tooth defect (1)

Mooth defect is the most common disease in dental diagnosis and treatment. The reasons such as caries , wear and even trauma can lead to different degrees of tooth tissue defects. The purpose of the treatment of tooth defect is to restore the shape and function of the tooth, and its methods can be divided into two types: direct filling and indirect restoration. For a long time, the direct filling method has been used to restore the shape and function of the affected tooth. However, the technical difficulties of dentin bonding caused by the special structure of dentin have always been the focus of scholars. In addition, the commonly used dental resin filling materials will produce polymerization shrinkage, form micro-leakage, cause secondary caries, and lead to the failure of restorative treatment. Commonly used indirect restoration methods include full crowns (metal crowns, porcelain crowns, all-ceramic crowns), post and core crowns , three-quarter crowns, and inlay restorations. Compared with other methods, inlay restoration has the advantages of less tooth grinding, less fracture of the prosthesis, good restoration of the adjacency relationship to prevent food impaction, and better restoration of the deformed tooth shape. With the development of modern prosthodontics, there is a trend of inlaying the restoration of tooth defects. Inlay is a restoration that is embedded in the tooth to restore the shape and function of the defective tooth. It has the advantages of grinding less tooth tissue and is widely used in clinical practice. With the improvement of the bonding level and the update of inlay materials, the indications of inlays have been continuously expanded, which has become the main development trend of the restoration of oral tooth defects. There is also a wide application of computer aided design/manufacturing (CAD/CAM) technology, which can complete the production of restorations in a more refined manner. It not only improves the work efficiency of doctors, but also reduces the number of patients' visits. In this paper, the research status of the classification, indications and contraindications, common postoperative problems in clinical practice, and types of inlay repair materials for inlay repair of dental defects are reviewed. Provide reference for clinical application and research..

Classification of inlays

In order to facilitate the preparation of tooth preparation for the restoration of posterior tooth defects, the development of clinical research and case exchange. classified the cavity types of the chairside CAD/CAM repairing cavity for posterior tooth defects into according to the cavity shape and location after tooth preparation : Inlays, onlays, full crowns, inlay crowns, super inlays, occlusal veneers, etc.
