A dental twin pin is a dowel pin used in dentistry. It has two parallel pins with a single head that engage two teeth and a single insertion in the dental dye2. The twin pins have brass pins along with stainless steel single sleeve for the model and stone casting during articulation1. The strength and precision of the twin pine stainless sleeve are higher, and it is more durable. It guarantees an outstanding fit and protects the dental stone during dental processing.
