Which clasp is preferred for a tooth-supported side with modification space?

The simple circlet clasp is preferred for a tooth-supported side with modification space due to its effectiveness in engaging the tooth for retention while providing aesthetic benefits. This clasp is designed to wrap around the retentive tooth, offering a strong retention feature without obstructing the other teeth in the arch.

In situations where modification spaces exist, a simple circlet clasp allows for retention that is straightforward and easily adjustable for adequate fit around the natural tooth structure. Its design minimizes bulk while maximizing retention, which is essential in maintaining the patient's comfort and functionality of the prosthesis.

Additionally, the simplicity of the circlet clasp contributes to its aesthetic appeal, making it less noticeable than other clasp types. This can be particularly important in the anterior regions where cosmetic concerns are paramount. In summary, the ability of the simple circlet clasp to provide optimal retention while maintaining an unobtrusive presence makes it the preferred choice in the scenario of a tooth-supported side with modification space.
