The Camper’s plane passes from the
1. lateral commissure of the mouth to the inferior edge of the ear
2. orbitale to the middle of the tragus of the ear
3. ala of nose to the superior edge of the tragus of the ear
4. outer canthus of eye to the most posterior point on the tragus of the ear
Prosthodontics
Answer: 3
The Camper’s plane is a facial reference plane that passes from the ala of the nose to the superior edge of the tragus of the ear. This plane is used in facial and cranial anatomy to describe the orientation of various structures and is often referenced in the field of orthodontics and surgery. It is useful for assessing the facial profile and the relationship between the nose, ears, and other facial features.
Porosity occuring in the bulky portions of the heat-cured acrylic complete dentures is due to
1) Insufficient pressure application during packing
2) Time lag between packing and curing
3) Directly placing the packed resin in water at 100 degree
4) Using a fluid pour technique
Prosthodontics
Answer: 3
Porosity in heat-cured acrylic dentures can occur due to several factors, but the most significant cause in this context is the direct placement of the packed resin in water at high temperatures (100 degrees Celsius). When the packed resin is subjected to such conditions, it can lead to rapid polymerization and the formation of bubbles or voids within the material, resulting in porosity. This is because the heat causes the monomer to vaporize, and if the vapor cannot escape, it leads to trapped air pockets.

If the clasp assembly is not being placed on a tooth adjacent to an edentulous
area, the minor connector must
be positioned
1. in the embrasure between two teeth
2. on the lingual surface of the tooth distal to the edentulous space
3. on the lingual surface of the tooth mesial to the edentulous space
4. on any tooth with a convex lingual surface
Prosthodontics
Answer: 1
Explanation: The minor connector should be positioned in the embrasure between
two teeth to provide adequate support and stability for the clasp assembly. This
positioning helps distribute forces evenly and maintains the integrity of the
prosthesis. The other options do not provide the same level of support.
