Question 74 · LDEK · Bridges
The prosthetic bridge will fulfill the long-lasting therapeutic goal if the abutments provide reliable support. Indicate the clinical aspects that should be considered to achieve clinical success while designing the bridge:
1) right clinical crown to root ratio, optimal 2:3, minimal 1:1;
2) right anatomical crown to root ratio, optimal 1:2, minimal 1:1;
3) sufficient number of abutments and their proper location;
4) well-anchored abutment teeth;
5) including Ante’s law describing the root surface area;
6) including Ante’s law describing the deflection (bending) of the span;
7) completed teeth development;
8) properly designed shape of the span;
9) usage of right metal alloys and ceramics; 10) adequate interocclusal space; 11) satisfactory oral hygiene.
The correct answer is:
2) right anatomical crown to root ratio, optimal 1:2, minimal 1:1;
3) sufficient number of abutments and their proper location;
4) well-anchored abutment teeth;
5) including Ante’s law describing the root surface area;
6) including Ante’s law describing the deflection (bending) of the span;
7) completed teeth development;
8) properly designed shape of the span;
9) usage of right metal alloys and ceramics; 10) adequate interocclusal space; 11) satisfactory oral hygiene.
The correct answer is:
- A. 1,3,4,5,7,10,11.
- B. 2,3,4,6,8,9,10.
- C. 1,3,5,7,8,9,11.
- D. 2,4,5,8,9,10,11.
- E. 1,4,5,7,8,9,10.
Hint
Separate clinical conditions of abutment support from design and material choices, and check what Ante's law actually describes.
