The primary advantage of implant supported prosthesis is
1. decreased bulk of the prosthesis
2. improved phonetics
3. maintenance of alveolar bone
4. improved proprioception
Prosthodontics
Answer: 3
Explanation: Implant-supported prostheses have the advantage of maintaining
alveolar bone due to osseointegration. This helps preserve the natural bone
structure and reduces the risk of bone resorption that is common with
traditional complete dentures, which can lead to changes in the patient's facial
profile over time.
In a double blind study
1. neither the persons collecting the data nor the subjects know all the details
of the study

4. the investigators and subjects are not allowed to see each other
Public Health Dentistry
Answer: 1
In a double-blind study, neither the participants nor the experimenters know who
is receiving the treatment or the placebo. This is to prevent any bias in the
study results due to the expectations of the participants or the researchers.
The statement that the investigator can omit data that fails to support the
hypothesis is not correct; data should be analyzed as is to maintain the
integrity of the study.
