What is the best bevel design for a Class IV composite resin fracture restoration on tooth #8 (maxillary right central incisor)?

For Class IV restorations involving the incisal angle of anterior teeth, a long straight bevel is the preferred preparation design. A long bevel maximizes the surface area for bonding, creates a gradual transition between the restoration and tooth structure for improved esthetics, and reduces the visibility of the margin. A scalloped bevel may also be used but is less predictable. A short bevel provides inadequate bonding surface, and no bevel results in a conspicuous restoration margin and reduced bond strength due to the butt-joint configuration.
