HOSA Dental Terminology Practice

What is a clasp in dental terminology?

1. A tool used for tooth extraction

2. A framework of a full denture

3. An extension of a partial appliance that grasps surrounding teeth

4. A substance used for tooth whitening

The correct answer is: An extension of a partial appliance that grasps surrounding teeth

In dental terminology, a clasp refers specifically to an extension of a partial appliance that grasps surrounding teeth. This is important in the context of removable partial dentures, where clasps are designed to provide retention and stability by securely fastening onto adjacent teeth. This secure fit helps maintain the position of the partial denture, preventing it from moving during function and improving the comfort for the patient. While tools for tooth extraction, frameworks for full dentures, and substances for tooth whitening serve their purposes within dentistry, they do not relate to the specific function and design of clasps in partial dentures. The primary function of a clasp is vital for ensuring that the appliance remains effective and comfortable for the wearer, making it a key component in restorative dental practices.
