What type of motion is utilized by straight chisels in periodontal surgery?

In periodontal surgery, straight chisels are specifically designed to use a push motion. This technique allows the clinician to effectively remove bone or soft tissue by pushing the chisel against the target surface. The chisel's sharp edge facilitates cutting through tissue as it is advanced forward, making the push motion the most efficient and effective for shaping and contouring the surgical area.

Using a push motion helps in maintaining control and precision, which is critical in delicate periodontal procedures. This contrasts with other tools that may use different motion types, such as pull or sliding motions, which may not provide the same level of effectiveness when employed with straight chisels. Understanding the mechanics of these instruments and their motions is essential for successful outcomes in periodontal surgeries.
