TOPIC: FINISHING AND CEMENTATION 🎯 KEY POINTS: 🔹In Chronic Xerostomic patient, cervical caries and periodontitis are prime reasons for FPD failure. 🔹Beilby layer is a microscopic surface layer produced during polishing of gold crowns. 🔹Metamerism is a phenomenon of an object appearing of different colours when viewed under different light source. 🔹The use of dissimilar […]
TOPIC: INSERTION, RELINING AND REBASING 🎯 KEY POINTS: 🔹Shim stocks are useful in verifying the presence and location of the occlusal contacts. 🔹Spoon denture is the maxillary interim RPD which is without clasp and whose palatal resin base resembles the shape of the spoon. 🔹It is usually used during periodontal treatment. 🔹RPD is preferred in […]
TOPIC: IMPRESSION MAKING IN REMOVABLE PARTIAL DENTURE 🎯 KEY POINTS : 🔹Dual impression technique is usually indicated in distal extension cases. 🔹Fluid waxes can flow at mouth temperature and be firm at room temperature. 🔹Iowa wax was developed by Dr E.S. Smith. 🔹Zinc oxide eugenol paste is the material of choice for recording edentulous ridges […]
TOPIC: MOUTH PREPARATION IN RPD 🎯 KEY POINTS : 🔹Shape of the rest seat in natural posterior teeth should be saucer-shaped. 🔹A rest helps to transmit the occlusal stresses parallel to the long axis of the tooth. 🔹The intentional conservative tooth reduction to prepare guiding planes is called enameloplasty 🔍 DEFINITION : 🔺ENAMELOPLASTY: The intentional […]
TOPIC: PRINCIPLES OF RPD DESIGN 🎯 KEY POINTS 🔹Gillett Bridge consists of a partial denture that utilizes the Gillett clasp system. It is composed of an occlusal rest which is notched deep into the occlusal axial surface with a gingivally placed groove and a circumferential clasp for retention. The occlusal rest is custom-made with a […]
WHAT ARE COMPONENTS OF RPD (REMOVABLE PARTIAL DENTURES) 🎯 KEY POINTS 🔹The fulcrum line is an imaginary line that joins the occlusal rests around which the prosthesis tends to rotate in function. 🔹Continuous gum denture is an artificial denture consisting of porcelain teeth and tinted porcelain denture base material fused to a platinum base. 🔹Fulcrum […]
