Learn the types of clasps used in removable partial dentures (RPDs) including I-Bar, C-Clasp, Roach Clasp, Flexible Clasp, and Tooth-Colored Clasp. Clear explanations with examples for NEET MDS, prosthodontics, and clinical practice.
IMPORTANT NOTES ABOUT FULCRUM LINES 📍 INTRODUCTION: In removable partial dentures (RPDs), achieving stability and retention is crucial for patient comfort and function. One of the key biomechanical factors in RPD design is the fulcrum line—an imaginary axis around which the denture rotates due to functional forces. This blog post breaks down fulcrum lines, their […]
TOPIC: SURGICAL AND PROSTHETIC PHASE 🎯 KEY POINTS: 🔹In implant-retained overdenture for completely edentulous patient, balanced occlusion or lingualized occlusion is given. 🔹In full fixed arch implant-supported bridges, there should be simultaneous contact on the anterior and posterior teeth in centric relation with anterior group function and multiple contacts in eccentric jaw movements. 🔹Guided bone […]
TOPIC: OSSEOINTEGRATION AND MATERIALS 🎯 KEY FACTS 🔹The term osseointegration was coined by P.I. Branemark in 1977. 🔹Minimum period required for osseointegration of the implants in the maxilla is 6 months and for mandible is 4 months. 🔹Implants should be placed after 16 years of age in a young patient once the alveolar growth is […]
TOPIC: Introduction, Diagnosis and Treatment Planning 🎯 KEY POINTS: 🔹Dahl of Germany introduced the mucosal inserts or button implants for maxilla in 1940. 🔹Dahl also conceived the concept of the subperiosteal implants. 🔹Goldberg and Gershkoff made subperiosteal implant with vitallium in 1948. 🔹Sollier, Chercheve and Small introduced the transosteal implant in 1953. 🔹L.I. Linkow in […]
TOPIC: MAXILLOFACIAL DEFECTS AND PROSTHESIS 🎯 KEY POINTS: 🔹Rapid prototyping technology used in maxillofacial prosthodontics is used to create three-dimensional models from a three-dimensional representation (CT scan or MRI). 🔹Essig splint is used to stabilize fractured or repositioned teeth and the involved alveolar bone. 🔹Inflatable balloon obturators were first described by K.W. Coffey in 1984. […]
TOPIC: INTRODUCTION OF MAXILLOFACIAL PROSTHODONTICS 🎯 KEY POINTS: 🔹Ambroise Pare (1517–1590) was first to close palatal perforations. 🔹Tycho Brahe (1546–1601) was famous Danish astronomer who made an artificial nose of gold and silver. 🔹First artificial eye was made of glass in 1579 in Venice. 🔹Pierre Fauchard (1728), considered as the father of modern dentistry, used […]
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: 🔹Lost wax technique was first used in casting of alloys by W.H. Taggart (1906). 🔹Gypsum-bonded investment material is used for casting gold alloys. 🔹Pickling is a method of cleaning gold casting by hot acid solution for several minutes. 🔹Phosphate-bonded investment is used for casting metal–ceramic alloys having […]
TOPIC: OCCLUSION RELATIONSHIP 🎯 KEY POINTS 🔹Group function is characterized by contact of all teeth on the working side and no contact on the balancing side during lateral excursions. 🔹Maximum limit of transverse hinge axis movement is 18–22 mm. 🔹Balanced occlusion is based on three classic theories of occlusion: Bonwill’s three points of occlusal balance, […]
