Clasps: what are they and why are they needed?

**Clamp** is a dental structure that is designed to create support for removable prosthetics, as well as to fix dentures in the oral cavity. In addition, the clasp can be used as a clasp blowtorch.

Why are clasps needed in dentistry? - For fixing complete removable dentures on the upper jaw - Used in cases where it is necessary to create support to improve occlusion and resist dislocation - Creating supports for partial removable dental structures, such as clasp dentures or Teflon crowns. - To create a bend on the frame of a plastic and metal denture - It can be used to achieve stabilization of metal orthopedic structures - Serves to connect the elements of two crowns to each other - Finding in cracks and defects in the dentition - Reducing friction inside the oral cavity and creating anatomical bends - Fixes partial denture on artificial gum, which is the basis of the dental system. Types of clasps There are several types of clasps: Clasp arches - installed along the dentition, serving as a support for removable dental structures. Fixed to obturation crowns. Very often used in combined dental systems. Made from cast steel or copper alloy. They are very durable and can last up to several decades, but require additional tooth preparation. Supramarginal plates (marginal crowns) - are used for partial stabilization and fixation of a denture from the side of the dentition. The tooth is fixed (an arch is used) to the necks and cusps of the tooth. They create a support for the denture structure. They are made from copper alloys or can be ceramic or plastic. Ligature discs – used for increased fixation of prosthetic structures in the presence of negative occlusion. Increases the strength of the denture frame. What types of clasp systems are there - Crown systems - this method of attaching a prosthesis has been used since the advent of plastic crowns, which were invented back in 1907. In this case, the denture is held in place with the help of crowns fitted on dental crowns - they are immediately made together with the denture and placed on the front teeth. This allows you to completely hide traces of a missing tooth. Before taking an impression, a rubber strip is attached over the crowns (it serves to tear it off), and after placing the prosthesis on the upper teeth, it is removed. Today, porcelain crowns are most often attached, or they can be made of metal, silver, gold and other materials. - Filling systems – in
