Step Cut
A type of tooth stump preparation technique for a dental crown is known as step cut. The tooth cut in the stump may be done in several ways such as groove cut, tangent cut and step cut. The video explains the tooth cut technique of step cut in greater detail. The main advantage of a tooth cut in a step shape is that it can be completed relatively quicker. A tooth cut is made in the form of a step using a roller. The step cut allows for a lot of space for the ceramic edges of the tooth. One disadvantage of a tooth cut in the form of a step is that the glue used in the cementing of the crown cannot flow away well within the step, resulting in a wide glue joint. This increases the risk of losing the glue or cement over a period of time and subsequent development of root cavity. While performing a tooth cut, the dental technician should be careful about size and width of the tooth cut. If the tooth cut is narrow, the crown will fit very tightly, which might lead to a ceramic spilt-off. Similarly, if the tooth cut is too wide, food particles will accumulate below the crown leading to cavities. The video explains the step cut method of a tooth cut in details as also the difference between the step cut and other methods of tooth cut.
