1. Diagnosis and tt planning in FDP-III
Dr Jitendra Rao
Dept of Prosthodontics

2. Consideration before FDP tt planning
Deep bite
Supraeruption of teeth
Short clinical crown
Para functional habits
Severe loss of tissues in the edentulous ridge
(Ridge defect)

3. Deep Bite/Traumatic bite
Overbite more than 3mm of anterior teeth often results in problems in the design and fitting of F.P.Ds
Sign of posterior occlusal collapse, with its accompanying loss of inter-arch space

4. Supra-erupted teeth
Overlooked clinically but will often complicate fixed partial denture design and fabrication
Inter-arch space obliteration
Short axial height of crown/prosthesis
How to counter this problem?
Coronoplasty of enamel
Extraction of tooth
Intrusion of crown
Intentional endodontic tt followed by crown

5. Parafunction habit
Any parafunctional habit like bruxism, clenching of teeth,nail biting,object biting
If a parafunctional habit is verified or even strongly suspected, the patient must be counseled regarding the effects of the habit and if necessary
Treatment for the adverse habit should be instituted

6. Tilted Molar Abutments
The over-all objective in molar uprighting is ideal positioning of the molar which will eventually become an abutment tooth for a fixed prosthesis. The ideal position will provide an optimal periodontal environment for the molar
Removable partial denture with molar uprighting springe – an appliance for uprighting the severely tilted bilateral molar abutment. This design is very cheap and can be planned at any age without hampering masticatory function during the course of treatment.

8. Cantilever FPDs
A cantilever FPD is one that has an abutment or abutments at one end only, with the other end of the pontic remaining unattached. This is a potentially destructive design with the lever arm created by the pontic
Abutment teeth for cantilever FPDs should be evaluated for lengthy roots with a favorable configuration, good crown root ratios and long clinical crowns.

9. Canine Replacement FPD/ Canine Rule

3.Symptoms are considered to be suffering from a TMJ disorder except
a. Facial disfigurement
b.Restricted Jaw movements
c.Clicking
d. Pain& tenderness

12. 4.Health of the attached gingiva can be best assessed by
a. Measurement on a radiograph
b.Application of force on tooth
c.Periodontal probe examination on buccal and lingual surface
d.Bleeding on examinations
5. An Intra-oral radiographic examination reveals all EXCEPT
a. Remaining bone support
b. Width of Periodontal ligament and trauma from occlusion
c. Quality of supporting bone, trabecular patterns and reactions to
functional changes, proximity to lamina dura
d. Bird eye view of the associated tooth and structure
6.Consideration for tt in FDP can be possible in
Edentulous space with no distal abutment
Multiple edentulous spaces
Tipped teeth adjoining edentulous space
Tooth having long and divergent root

13. 7.The major biomechanical factors which affect the design of an FPD are:
Length of edentulous Ridge
Pontic design
Connector design
The direction of the forces acting on the FPD
8.Ideal crown-root ratio for a tooth to be utilized as a fixed partial denture abutment is 2:3
1:1
2:3
1:1.75
1:1.5

14. 9. Non rigid connector, keyway on -distal contours of a abutment and key on mesial side of the distal pontic are the features of
a. Pier abutments
b. Tilted molar abutments
c.Cantilever abutment
d. Double abutments
10.Arcon articulator 
Condylar housing is in lower member
Condylar housing is in upper member
Have no Condylar housing
Is fully adjustable articulator
11. Hinge axis is  
Transverse axis
Vertical axis
Saggital axis
Coronal axis

15. 12.Jepsen’s rule is applicable for
Pontic selection
Abutment selection
Crown root ratio for FPD
Root surface area of abutment
13.Tilted molar abutment is contraindicated for FPD
> 150
< 200
>250

16. 14.Reason for not replacing the maxillary canine through FPD is all EXCEPT
Canine is outside the inter-abutment axis
Longest root in the arch
LI is weakest in ant and Ist PM is weakest in post region
Prone for pulp exposure
15. Tooth having minimum root surface area
Maxillary CI
Mandibular CI
Mandibular LI
Maxillary LI
