Tinplate Steel Sheet Woodworking Machine - Telescopic work – Foo Tian

Telescopic work: the telescopic denture consists of the primary crowns or caps made of precious or non precious dental alloys that will be cemented on the prepped teeth, the secondary crowns that are slipping over the primary caps and thus maintaining the bridge through sliding friction tight on the teeth. Telescopic denture is also known as overlay denture. A complete denture that is supported by both soft tissue and natural teeth that have been altered so as to permit the denture to fit over them. The altered teeth may have been fitted with short or long copings, locking devices, or connecting bars.
