  1. 1. INTRODUCTION<br />THE DISCIPLINE OF FIXED PROSTHODONTICS<br />
  2. 2. Course Name:PROSTHODONTICS I (FIXED PARTIAL DENTURE)<br />Course Description<br />Study of fixed partial prosthesis considering the biological requirements for restoring the normal oral functions and aesthetics.<br />Course Credit:<br />4 units – 2 units lecture(75%), 2 units laboratory (25%)<br />Contact Hours:<br />2 hours lecture/6 hours laboratory per week<br />Pre-requisite:<br />Dental Material<br />Placement:<br />2nd year, 1st semester<br />
  3. 3. Course Name:PROSTHODONTICS I (FIXED PARTIAL DENTURE)<br />Course Objectives:<br />To develop the skills in making accurate diagnosis for jacket crowns and fixed partial prosthesis and to formulate a concise treatment plan;<br />To describe the different principles of tooth preparation and the indications and contraindications of the different types of artificial crowns and fixed partial restorations.<br />Course Outline:<br />Overview of fixed partial prosthesis<br />Diagnosis and treatment planning<br />Principles of tooth preparation<br />Temporary restorations<br />Artificial crowns<br />Fixed partial prosthesis<br />Impression materials<br />Indication of Different Cements<br />Clinical aspects and troubleshooting<br />Principles of occlusion <br />
  4. 4. Course Name:PROSTHODONTICS I (FIXED PARTIAL DENTURE)<br />Textbook and References:<br />Johnston, Modern Practice in Fixed Prosthodontics, 4th ed.<br />Rosenstiel, Contemporary Fixed Prosthodontics, latest ed.<br />
  5. 5. DENTISTRY / defined<br />It is the health science that encompasses the:<br />Study and application of measures designed to prevent the deterioration of oral structures and<br />Use of pertinent clinical procedures to improve the oral health of those treated.<br />
  6. 6. DENTISTRY/ RAMIFICATIONS<br />The relief of pain<br />The treatment of oral diseases<br />The maintenance of masticatory efficiency<br />The maintenance and or restoration of the esthetic qualities of the mouth and face.<br />* outcome<br />
  7. 7. DENTISTRY / functions of dental practice<br />Research<br />Educational efforts<br />Preventive efforts and<br />Clinical efforts<br />So that an ever increasing number of people can avoid the loss of teeth.<br />combine and coordinate <br />
  8. 8. DENTISTRY / patient’s role in preventive dentistry<br />If the patient begins coming to the dentist early in life and is convinced of the dividends to be earned from a policy of :<br />Preventive therapy<br />Correct oral hygiene and <br />Prompt repair of the tooth when a carious lesion has penetrated the enamel, <br />there should be little need later for major restorative operations.<br />
  9. 9. DENTISTRY / duty of the dentist<br />If a tooth must be lost, it is the duty of the dentist to ---<br /> inform the patient that the space should be filled after surgery (as soon as healing and shaping of the ridge tissue are complete).<br />The significance of keeping the arches intact must be stressed…<br />WHY?<br />
  10. 10. DENTISTRY / duty of the dentist<br />The loss of one tooth can effect changes in: <br />1. Position of the teeth and <br />2. contact relationships of all teeth remaining in the mouth.<br />
  11. 11. DENTISTRY / duty of the dentist<br />Sequelae in the change of tooth position and contact relationship:<br />
  12. 12. CHARACTERISTICS OF AN IDEAL PROSTHESIS <br />Contribute to mastication,<br />It should augment the ability of the patient to enunciate,<br />It should restore and preserve contacts between the abutments and the approximating teeth and also all other teeth in the arch, and <br />It should maintain the positions of the opposing teeth and the health of the supporting structures.<br />
  13. 13. DEFINITION OF TERMS prosthodontics<br />Branch of dentistry <br />(It is the health science that encompasses the :<br />study and application of measures designed to Prevent the deterioration of oral structures and <br />use of pertinent clinical procedures to improve the oral health of those treated.)<br />pertaining to the restoration and maintenance of<br />oral function, <br />comfort, <br />appearance, and <br />health of the patient <br />by:<br />the restoration of the natural teeth or <br />the replacement of missing teeth and contiguous oral and maxillofacial tissues with artificial substitutes, or<br />by both.<br />

  15. 15. DEFINITION OF TERMS removable prosthodontics<br />Branch of prosthodontics concerned with the replacement of teeth and its contiguous structures <br />for edentulous or <br />partially edentulous patients <br />by artificial substitutes <br />that are removable from the mouth.<br />
  16. 16. DEFINITION OF TERMS removable prosthodontics<br />
  17. 17. DEFINITION OF TERMS removable partial denture <br />Is a prosthesis that replaces tooth/teeth and contiguous structures for partially edentulous patients.<br />It can be removed from the mouth by the patient during oral hygiene procedures and for other purposes.<br />
  18. 18. DEFINITION OF TERMS fixed prosthodontics<br />Branch of prosthodontics concerned with the replacement or restoration of teeth, or both<br />by artificial substitutes <br />that are not removable from the mouth.<br />
  19. 19. DEFINITION OF TERMS fixed prosthodontics<br />
  20. 20. DEFINITION OF TERMS maxillofacial prosthetics <br />Branch of prosthodontics concerned with the replacement or restoration, or both, of the stomatognathic and associated facial structures <br />by artificial substitutes <br />that may or may not be removed.<br />
  21. 21. DEFINITION OF TERMS maxillofacial prosthetics <br />
  22. 22. DEFINITION OF TERMS prosthesis <br />Any artificial replacement of a missing body part.<br />
  23. 23. DEFINITION OF TERMS crown<br />An artificial replacement that restores missing tooth structure by <br />surrounding most or all of the remaining structure with a material such as <br /> 1. cast metal, <br /> 2. porcelain, or <br /> 3. a combination of materials such as metal and porcelain.<br />It is intended to reproduce <br />both the form and the function of the tooth and, <br />in some instances, to restore and enhance the appearance.<br />
  24. 24. DEFINITION OF TERMS full veneer crown<br />An extracoronal restoration that involves all or nearly all of the surface of the clinical crown of a tooth.<br />
  25. 25. DEFINITION OF TERMS partial veneer crown<br />A restoration that usually includes all but one surface of the tooth – <br />hence the frequently heard but not completely accurate term, three quarter crown.<br />
  26. 26. DEFINITION OF TERMS fixed prosthesis / fixed bridge<br />Non removable prosthesis that is <br /><ul><li>rigidly attached to one or more abutment* teeth </li></ul>*(It is the natural tooth or teeth usually two or more, that supports the prosthesis and to which it is attached.)<br /><ul><li>To replace missing tooth structure
  27. 27. To replace one or more lost or missing teeth. </li></ul>The term fixed partial denture is sometimes used.<br />
  28. 28. DEFINITION OF TERMS retainer<br />Is the restoration, usually a crown, rebuilding the prepared abutment tooth, by which the bridge is attached to the abutment and to which the pontic is connected.<br />
  29. 29. DEFINITION OF TERMS pontic<br />Is the substitute for the lost tooth, both esthetically and functionally.<br />
  30. 30. DEFINITION OF TERMS joint or connector<br />Is the part of fixed prosthesis that unites the retainer with the pontic or that joins the individual units of the prosthesis.<br />It may be rigid, as are both the cast and soldered joint, or non rigid as is the dovetail joint.<br />
  31. 31. types of connectors<br /><ul><li>Rigid Connectors
  32. 32. Non Rigid Connectors</li></li></ul><li>RIGID connectors<br />KINDS OF RIGID CONNECTORS<br />Cast<br />Soldered<br />Welded<br /> - connectors to be cast are shaped in wax as part of a multiunit wax pattern<br /> - uses intermediate alloy whose melting temperature is lower than that of the parent metal (parts being joined are not melted)<br />
  33. 33. RIGID connectors<br />KINDS OF RIGID CONNECTORS<br />Cast<br />Soldered<br />Welded <br /> - connection is created by melting adjacent surfaces with heat or pressure.<br />
  34. 34. NON RIGID connectors<br />Not rigidly attached to the abutment.<br />Segmenting of large, complex FPD into shorter components.<br />Indications :<br /><ul><li>Uncertainty of abutments prognosis
