Incorrect wedge placement during a dental procedure can lead to overhang or cupping of the finished restoration. When wedges are not properly positioned, they do not create the right contact and contour needed to form a seamless restoration with the adjacent tooth structure. This can result in excess material pooling outside the intended area, creating overhangs that can trap food debris and plaque, leading to possible decay or periodontal issues. Additionally, cupping may occur when the restoration does not appropriately fill the space or contour of the tooth, compromising both aesthetics and function. A proper wedge placement is crucial in achieving a stable and well-contoured dental restoration.
