Types of fixed prostheses from Emilio Aguinaldo College, Philippines

  1. 1. Types of Fixed prostheses • • • • • • • Inlays Pinledge Onlays Artificial crown Veneer Jacket Post crown
  2. 2. Inlays • fits exactly by cementing medium; an intracoronal restoration- surrounded by tooth structure.; not suitable anchor for casting in FPD.
  3. 3. Inlay classification: • Class I: occlusal of posterior (bicuspid and molars) • Class II: proximal (M/D) and occlusal of the posterior (MO, MOD, DO).
  4. 4. • Class III: proximal of the anterior • Class IV: proximal and incisal of anterior. • Class V: facial or lingual surface including the cervical third of the teeth (anterior and posterior).
  5. 5. Pinledge a thin casted gold restoration that covers the lingual surface of anterior tooth involving 1 of the proximal surface. - Categorized as specialized form of inlay - Has 2/3 parallel pin with a depth of 1.52mm. - Most aesthetic , most conservative type used in FPD. - Least reliable, potentially destructive to an abutment because of the pin.
  6. 6. Onlays a casted gold restoration in (M,D,O,L,B) up to the extend of carries ; usually up to the middle third. - Partially capped; smallest form of FPD. - An extacoronal restoration.
  7. 7. Artificial crown a fixed prosthetic restoration which covers more than half of the tooth surface that is exposed inside the patient’s mouth. -categorized in various kind: Complete crown: covers the entire surface/anatomy of the clinical crown. Partial crown: a restoration designed to replace 1 or more missing natural teeth. -Retains or attaches to primary abutment.
  8. 8. Veneer a complete coverage of submetal structure overlying with either porcelain or plastic(acrylic) for aesthetic effect.
  9. 9. Jacket a complete crown for anterior tooth made entirely of porcelain or acrylic.
  10. 10. Post crown a complete crown of any kind – metal or veneer. - Uses a “core” where the crown is attached.
