3. “Most clinicians also choose an RPD for a partially
edentulous patient if they need to restore lost residual
ridge, achieve appropriate esthetics, increase
masticatory efficiency, and improve phonetics but are
unable to do so with dental implants or fixed partial
dentures due to financial constraints or patient desires”
- Bohnenkamp DM Removable Partial Dentures :
Clinical Concepts, Dent Clin N Am 58 (2014) 69–89
“Problems related to RPDs may be associated with
errors in diagnosis and treatment planning, including
inadequate mouth preparation “
- McCord JF et al Dent Update 2003; 30: 88–97

4. According to GPT 8
 Diagnosis : the determination of the nature of a
disease
 Treatment plan : the sequence of procedures
planned for the treatment of a patient after
diagnosis

5.  The delineation of each patient’s uniqueness
occurs through the patient interview and clinical
examination process.
 The ultimate treatment is individualized to
address disease management and the
coordinated restorative and prosthetic needs
that are unique to the patient.

6.  understanding the patient’s desires or chief
concerns/complaints regarding his or her
condition
 ascertaining the patient’s dental needs through
a clinical examination,
 developing a treatment plan that reflects the
best management of desires and need
 Executing appropriately sequenced treatment
with planned follow-up

7. The dentist should follow a sequence
that includes:
1. Chief complaint and its history
2. Medical history review
3. Dental history review, especially
related to previous prosthetic
experience(s)
4. Patient expectations

8.  Personal and psychological factors are
significant to the success of prosthodontic
treatment
 House classification
- Philosophical
- Exacting
- Hysterical
- Indifferent
House classification
revisited :
- Ideal
- Submitter
- Reluctant
- Indifferent
- Resistant

9.  The process of clinical examination involves
two stages :
- Medical examination
- Oral examination
A comprehensive medical history includes :
- systemic disorders (Chronic degenerative or
dysfunctional diseases)
- Medication history
- Diet
- Habits

10. Systemic disordes include:
 Hypertension
 Diabetes
 Pernicious anemia
 Vitamin or nutritional deficiencies
 Osteoporosis
 Chronic pulmonary disease (i.e.,emphysema and
chronic bronchitis)

11.  Climacteric (i.e., menopausal changes)
 Parkinsonism
 Salivary gland disorders
 TM disturbances
 Post radiation therapy
 Bell ’ s palsy
 Lichen planus
 Fungal infections

12. An oral examination should be accomplished in
the following sequence :
 visual examination,
 pain relief and temporary restorations,
 radiographs,
 evaluation of abutment and periodontium,
 vitality tests of individual teeth,
 determination of the floor of the mouth position,
 Oral prophylaxis and impressions of each arch.

13. This includes : extra oral and intra oral examination.
TMJ - tenderness, mouth opening deviation & clicking

14.  No of teeth present with their clinical evaluation
 Malposed teeth
 Carious teeth
 Existing restoration- sensitivity to percussion
 Periodontium
 Residual ridges
 Saliva
 Investing structures
 Occlusion and occlusal plane
 Oral hygiene index

15.  to determine the need and management of
acute needs and whether a prophylaxis is
required to conduct a thorough oral
examination.
 to relieve discomfort arising from tooth defects
 the extent of caries and arrest further caries
activity

16.  areas of infection and other pathologies
 the presence of root fragments, foreign objects,
bone spicules and irregular ridge formations
 the presence and extent of caries and the
relation of carious lesions to the pulp and
periodontal attachment
 evaluation of existing restorations : evidence
of recurrent caries, marginal leakage, and
overhanging gingival margins

17.  the presence of root canal fillings
 evaluation of periodontal conditions present
 to evaluate the alveolar support of abutment
teeth, their number, the supporting length and
morphology of their roots
 the relative amount of alveolar bone loss suffered
through pathogenic processes, and the amount of
alveolar support remaining

18.  To locate inferior borders of lingual mandibular
major connectors.
 oral hygiene status before prosthodontic treatment is
important.
 The impression for the diagnostic cast is usually
made with an irreversible hydrocolloid in a stock
(perforated or rim lock) impression tray.

19. • Anatomic consideration
- Root length, size and form
• vitality tests
• caries evaluation
• Periodontal health
• Malpositions
• Analysis of Occlusal
Factors

20. • Supplements oral examination
• Permit a topographic survey of the dental arch
• Patient education and motivation
• Custom tray fabrication
• Constant reference
• Patient's record

21.  verification of appropriate
mouth modifications for a
removable partial denture.
 To determine the most
desirable path of placement
that will eliminate or minimize
interference to placement and
removal
 To locate and measure areas
of the teeth that may be used
for retention

22.  To determine whether tooth and
bony areas of interference will need
to be eliminated surgically or by
selecting a different path of
placement
 To determine the most suitable path
of placement that will permit
locating retainers and artificial teeth
to the best esthetic advantage.
 To permit an accurate charting of
the mouth preparation to be made
including the preparation of
proximal tooth surfaces to provide
guiding

23. • Occlusal plane & relationships
• Abutment tooth contours
• Rest seat areas
• Interarch space
• Residual ridge relation
• Tissue contours

25.  The objectives of any prosthodontic treatment
may be stated as follows:
 the elimination of disease
 the preservation, restoration, and maintenance
of the health of the remaining teeth and oral
tissues
 the selected replacement of lost teeth; for the
purpose of restoration of function
 comfort and in esthetically pleasing manner

26.  Based on diagnostic findings, The American
College of Prosthodontists (ACP) has
developed a classification system for partial
edentulism
 Criteria 1: Location and extent of the
edentulous area(s)
 Criteria 2: Abutment conditions
 Criteria 3: Occlusion
 Criteria 4: Residual ridge

27.  Edentulous area confined to a
single arch
 Abutment conditions -No
preprosthetic therapy is indicated
 Occlusal characteristics- Class I
molar jaw relationships are seen
 Residual bone height of ≥21 mm

28.  Edentulous area – Both arches
 Abutment- Abutments in 1 or 2
sextants have less tooth
structure or support intra or extra
coronal restorations
 Occlusion- Localized adjunctive
therapy Class I molar and jaw
relationships are seen
 Residual bone height of 16 to 20
mm

29.  Any posterior maxillary or
mandibular edentulous area
greater than 3 teeth or 2 molars.
Any edentulous areas including
anterior and posterior areas of 3 or
more teeth.
 Abutments in 3 sextants have
insufficient tooth structure to retain
or support intracoronal or
extracoronal restorations.

30.  Entire occlusion must be
reestablished. Class II molar
and jaw relationships are
seen.
 Residual alveolar bone
height of 11 to 15 mm

31.  Any edentulous area or
combination of edentulous
areas requiring a high level of
patient compliance
 Abutments in 4 or more
sextants have insufficient
tooth structure to retain or
support intracoronal or
extracoronal restorations.

32.  Entire occlusion must be
reestablished, including
changes in the occlusal
vertical dimension. Class II
div 2 and Class III molar and
jaw relationships are seen.
 Residual vertical bone height
of ≤10 mm

33.  Individual diagnostic criteria are evaluated and the
appropriate box is checked. The most advanced finding
determines the final classification
Classification System for Partial Edentulism, Journal of Prosthodontics Vol.
11, no. 3, 2002: 181 – 193.

34. 1. Any single criterion of a more complex class
places the patient into the more complex class.
2. Consideration of future treatment procedures must
not influence the diagnostic level.
3. Initial preprosthetic treatment and/or adjunctive
therapy can change the initial classification level.

35. 4. If there is an esthetic concern/challenge, the
classification is increased in complexity by one
level in Class I and II patients.
5. In the presence of TMD symptoms, the
classification is increased in complexity by one or
more levels in Class I and II patients.
6. In the situation where the patient presents with
an edentulous mandible opposing a partially
edentulous or dentate maxilla, Class IV.

36.  Implant supported fixed dental prosthesis
 Fixed dental prosthesis
 Removable partial denture
 Complete denture
 Combination of the above
 No treatment at all

37.  Distal extension situations
 After recent extractions
 Long span
 Need for cross-arch stabilization
 Excessive loss of residual bone
 Sound abutment teeth
 Abutment with guarded prognosis
 Economic considerations

38.  It is a communication model
 a process where the provider and the patient
identify together the best course of care.
 it addresses the need to fully inform patients
about risks and benefits of care options
 ensures that patient values and preferences
play a prominent role in the process.
