摘要：This article presents an important topic in the field of dental medicine. Reconstruction of the contact point in the lateral interdental area is obtained using a large number of type techniques, with different materials and instruments. The centripetal build up technique involves the initial restoration of the proximal absent wall, thus transforming the second-class cavity into a first-class cavity, followed by it’s restoration. This technique provide a correct, appropriate contact point and an easy restoration of the occlusal morphology.
