Chapter 2 – Clasp-Retained Partial Denture

  1. In chronological order of accomplishment, give the six sequential, correlated phases in treating a partially edentulous patient with removable prostheses.

      • First phase: Patient education, patient should be educated thouroughly and understand the tx before any treatment is decided on or started.

      • Second phase: diagnosis (Health hx, dental health, etc.), treatment planning (surveying) , design of the partial denture framework, treatment sequencing and execution of mouth preparations (get good support, retention)

      • Third phase: Provision of adequate support for the distal extension denture base (not needed for tooth supported partials, need to make the distal base based on the functional impression / form (soft tissue shape under function) rather than the anatomic ridge form)

      • Fourth phase: establishment and verification of harmonious occlusal relationships and tooth relationships with occlusal and remaining natural teeth.

      • Fifth phase: initial placement procedures, adjustments to contours and bearing surfaces and to occlusal surfaces. Also, review patient instructions.

      • Sixth phase: follou up services, recall appointments

  2. If the dentist and the patient share responsibility for the success of treatment, what must be undertaken to prepare patients to accept their responsibility?

      • Inform patient of the benefits of a removable partial denture

      • Advise Patients on proper oral care and maintenance procedures

      • Educate on use of the prosthesis to avoid misuse

  3. Because treatment planning is the sole responsibility of the dentist, which if any of the following may be omitted as noncontributory to total treatment: (1) a complete health history, (2) a history of past dental experiences (3) an oral examination, (4) a radiographic examination, (5) an evaluation of occlusal relations of remaining teeth (6) a survey of diagnostic casts, (7) cost or (8) patient desires?

      • Neither 7 or 8 are mentioned as parts of the treatment plan. (see page 14)

  4. A specific design of the removable restoration must be planned before mouth preparation procedures. The dentist (can-should not) delegate the responsibility for the design to a dental laboratory technician.

      • The dentist should not delegate the responsibility for the design to a dental laboratory technician.

  5. Stability in a removable restoration (is – is not) desirable to help maintain the health of oral structures. A tooth – supported restoration usually (can – cannot) be made more stable than a restoration supported by teeth and residual ridges.

      • Stability in a removable restoration is desirable to help maintain the health of oral structures.

      • A tooth – supported restoration usually can be made more stable than a restoration supported by teeth and residual ridges.

  6. In the fifth phase of treatment (initial placement of the restorations), three things are done before the patient is given possession of the denture(s). Two of these are (1) correction of denture base contours and occlusal discrepancies that may have resulted form processing and (2) review of patient education, including adjustment expectations. What other step must be accomplished during the appointment?

      • Ensure that the patient understands the uses of the RPD and how to care for the denture and soft tissues.

  1. What is the purpose of periodic recall of patients treated with removable partial dentures?

      • For evaluation of the response of the oral tissues, soft tissue changes

      • maintain oral health

      • evaluation of the acceptance of the prosthesis by the patient

      • Evaluate patient oral hygiene

  2. What is the one predominant reason why the clasp-type or partial denture is used more often in most practices than is the internal attachment type of prosthesis?

      • Cost

  3. Deficiencies in design and fabrication and those related to patient education are the culprits of limited success in treatment with removable prostheses. Avoiding these deficiencies will make the goal of prosthetic dentistry obtainable. This goal is to ______________, ___________, and ______________.

      • promotion of oral health

      • restoration of partially edentulous mouths

      • elimination of the ultimate need for complete dentures

Chapter 3

  1. Would you agree that the primary purpose of a classification is to enhance communication among dentists? Support your answer?

A: Yes and no. There are several classifications that have been proposed and the use of it would facilitate communication. In this book the Kennedy classification is the only one used as a way to better communication. So the use of classifications for partially edentulous areas does help communication, but one classification should be used.

  1. Many classification systems have been propsed; however, the most widely accepted system in the US is the one proposed by _______________ in 1925.

A: Dr. Edward Kennedy

  1. A classification of partially edentulous arches should satisfy at least three requirements. List them.


      • It should permit immediate visualization of the type of partially edentulous arch that is being considered

      • It should permit immediate differentiation between the tooth supported and the tooth and tissue supported removable partial denture

      • It should be universally acceptable

  1. Kennedy divided al partially edentulous arches into _______ main types.

A: 4

  1. What is meant by modification space?

A: Edentulous areas in an arch that are variations to the basic 4 classifications. Edentulous areas other than those determining the classification.

  1. Which two classes of partially edentulous arches have the greatest incidence of occurrence according to Skinner?

A: Skinner classification type III

  1. Dr. O.C. Applegate contributed greatly to the application of the original Kennedy classification system. What was this contribution?

A: He contributed eight rules governing the application of the Kennedy method

  1. Classify the partially edentulous arches illustrated in Figure 3-3 (p. 23)

A. Kennedy Class IV

B. Kennedy class I

C. Kennedy class II

D. Kennedy Class III

E. Kennedy Class III

F. Kennedy Class III

G. Kennedy Class IV

H. Kennedy Class II

I. Kennedy Class III
