3 Credits / Quarter 6 (Winter, Second Year)
This is the second course in a three course sequence of preclinical fixed prosthodontics. The didactic course and laboratory exercises emphasize the restoration of endodontically treated teeth, preparation of multiple abutments for fixed prostheses, multiple unit provisional restorations, preparation of teeth for partial veneer crowns for single or multiple unit prostheses, pontic design, selection of rigid and non-rigid connectors in fixed prostheses, and general fundamentals in treatment planning for fixed prostheses.
Students will gain knowledge in the planning and restoration of missing teeth with fixed prostheses, planning and designing for restoration of endodontically treated teeth. A high standard of ethical behavior is expected throughout this course (2-20, 2-21). Clear guidelines are presented in the course manual preface and course outline to ensure ethical conduct.
Course objectives include the ability to:
- Design, prepare, and restore four endodontically treated teeth using a variety of post systems including: a custom cast post & a preformed cast post, both with cast cores; a preformed glass fiber post & a stainless steel post, both with composite cores; as well as making an impression for an indirect cast post and core.
- Prepare two abutments for CVGC retainers of a three-unit fixed prosthesis replacing a single molar tooth, fabricate an appropriate provisional restoration, obtain impression, working cast and complete selected laboratory procedures; (2-25.g)
- Prepare a posterior tooth for a partial veneer crown restoration.
- Prepare two teeth for complete ceramic crown restorations.
Lecture topics include: course description; restoration of endodontically treated teeth, cast post and core foundation restorations; prefabricated alloy and esthetic post and core restorations; periodontal status of abutments for fixed partial dentures, mouth preparation, clinical decisions; abutment selection; retainer selection; multiple unit provisional restorations; post and core try-in and cementation; pontic and connector design; torch soldering technique; dowel and/or pin retained foundation restorations; cementation procedures; tooth preparation for partial coverage restorations; and treatment planning for fixed partial dentures.
Assessment of Competency
To successfully meet the requirements of this course, the student is expected to attend lectures and laboratory sessions, complete all laboratory projects and to demonstrate her/his knowledge of the lecture and assigned reading material through quizzes, midterm and final written examinations as well as demonstrate skills through simulated clinical and laboratory projects and practical examinations. Students must pass all tooth preparation and provisional restoration practical examinations with 70% or greater. Tooth preparation and provisional restoration practical examinations include both faculty and student self-evaluations with recognition for closeness between faculty and student marks.
- Attend eight, two-hour lectures, read selected references related to each topic and pass a midterm and final (multiple-choice format) written examination.
- Practice preparing dentoform teeth for four different designs of indirect restorations using evaluation criteria for reference, manual instructions, and faculty instruction for guidance; subsequent to the skill development for each preparation design, a timed, clinically simulated, competency practical examination must be successfully completed with a grade of 70% or greater
- Attend ten, five-hour laboratory sessions and complete several clinically simulated projects at a satisfactory level
- Also, in a clinically simulated environment, students must successfully complete (with a 70% or greater grade) a series of procedures analogous to the Restorative Clinic setting. This practical examination is extended over several weeks and includes several procedures including study casts, diagnostic waxing, treatment planning and an unsupervised tooth preparation. In addition to this, there are graded procedures including a provisional restoration, a final impression and non-graded procedures including a PVS bite registration and a detailed written laboratory prescription.
Effective Winter Quarter 2007, completion of on-line course evaluation is a requirement of this course. Failure to comply will result in an “Incomplete” grade being assigned.
- UWSOD Competency 2: Communicate the risks and benefits of proposed care and alternative treatment strategies available, then obtain expressed consent for treatment conveyed by a patient or legal guardian.
- UWSOD Competency 3: Formulate a comprehensive treatment plan based on diagnostic findings, then implement treatment in a safe, properly sequenced and timely manner.
- UWSOD Competency 5: Recognize the limits of their expertise and seek consultation with other health care providers to facilitate patient care.
- UWSOD Competency 7: Manage pulpal and periradicular disease.
- UWSOD Competency 14: Manage periodontal diseases.
- UWSOD Competency 16: Manage diseases and conditions of the teeth.
- UWSOD Competency 17: Manage replacement of teeth for the partially or completely edentulous patient.
- UWSOD Competency 21: Recognize the role of lifelong learning and self-assessment in maintaining competency.
- UWSOD Competency 22: Utilize critical thinking in assessing technical and scientific information for use in identifying patient needs and treatments.
Assurance of Competencies
Students are judged competent to proceed to the third quarter of preclinical fixed prosthodontics when they have successfully completed the following:
- two written examinations judging student’s knowledge of fixed prosthodontics, associated disciplines, and relevant dental technology.
- two tooth preparation competency practical examinations and a prefabricated provisional restoration.
- a competency practical examination which includes: a tooth preparation, bite registration, final impression, a custom-made provisional restoration, and a written laboratory prescription.
- completion of two cast dowel-core foundation restorations , an impression for a cast dowel-core, an esthetic post and composite core restoration, a SS post and composite core restoration, three CVGC retainers, a solder index and a provisional three-unit posterior FPD restoration, two complete ceramic crown preparations (all exercises to be completed at a clinically acceptable level).
