Forces acting on the abutment tooth in an FPD can be effectively minimised by
1) Directing the forces perpendicular to long axis of the crown
2) Directing the forces along the long axis of the crown
3) Both of the above
4) None of the above
Prosthodontics
Answer: 2
Directing forces along the long axis of the crown is an effective way to minimize the stresses on an abutment tooth in a fixed partial denture (FPD). This allows the tooth to function more naturally and reduces the likelihood of complications such as root fracture or periodontal damage

FPDs are generally contraindicated and the missing teeth replaced with a RPD,
in patients less than
1. 17 years old
2. 10 years old
3. 30 years old
4. 46 years old
Prosthodontics
Answer: 2
FPDs are generally contraindicated for several reasons:
Growth and Development: Children are still in their
growth phase, and their jaws and teeth are developing. Placing a fixed
prosthesis can interfere with normal growth patterns and may require
adjustments or replacements as the child grows.
Eruption of Permanent Teeth: In younger patients,
especially those under 10, many of the permanent teeth have not yet erupted.
Using FPDs in this age group can complicate future dental treatments, as the
position of the teeth may change with the eruption of permanent teeth.
