Abstract:

The aims of tooth restoration of endodontically treated teeth are to protect the remaining dental tissue; restore coronal morphology, functions and aesthetics; prevent bacterial microleakage and ensure periodontal healthy; prevent fracture of the restorations and reduce the wear from antagonist teeth. This article reviews the preservation and minimally invasive restoration of endodontically treated teeth. The results of the literature review show that tooth fracture resistance decreases after root canal treatment, the amount of remaining tooth tissue is an important factor affecting the success of root canal treatment, and the neck is the stress concentration area of tooth tissue, the traditional full crown and postcore crown have a certain amount of abrasion on the healthy neck teeth tissue, which will further reduce the bending resistance of the teeth and may cause the teeth to fracture. With the development of bonding technology, composite resin materials and ceramic materials, there are fewer molar tissues removed when resin, inlay, onlay, overlay and inlay crown are used to repair tooth defects, which can better preserve the remaining tooth tissues, especially the neck tooth tissues. After root canal treatment, only the pulp cavity of the tooth can be directly repaired by resin. When the marginal ridge is absent, minimally invasive restoration methods, such as inlay, onlay, and inlay crown, can be selected according to the number of marginal ridges removed and the thickness of the remaining dental tissue.

Key words: Tooth defect, Root canal treatment, Inlay, Onlay, Minimally invasive, Computer aided design/computer aided manufacturing
