It is a good idea to use a plastic instrument to protect the tissue while refining the finish line in dental impression making.

True

It is recommended to designate a specific instrument for dental impression making to avoid damaging it quickly.

True

If making a polyether impression, it is essential to use PVS adhesive.

False

Using the wrong adhesive with stock trays can lead to proper fusion and distortion in dental impressions.

False

Pulling the cord down slightly with a plastic instrument while refining the preparation can help prevent accidentally pulling out the cord with the diamond.

True

It is recommended to go around the finish line twice when making a dental impression to ensure any air bubbles trapped are pushed out with the second layer.

True

To ensure a good dental impression, it is crucial to capture the entire finish line and some uncut tooth beyond it all the way around.

True

According to the passage, capturing two millimeters of uncut tooth beyond the finish line is necessary to make a good dental impression.

False

The technique of going around the finish line twice when making a dental impression is applicable only for optical scans and not for physical impressions.

False

Removing the impression from the mouth immediately after making it is key to ensuring a successful dental impression.

False

The finish line should have bubbles and gross voids to ensure a good impression.

False

The machine used for mixing heavy body material has a timer built into it.

True

Patient comfort techniques during dental impressions involve leaning the patient's head backwards to prevent gag reflex.

False

Holding the patient in a headlock during dental impressions is considered reassuring and helpful for patients.

True

One of the tricks for impression making to distract patients is asking them to lift their legs while making the impressions.

True

It is critical for the dental professional to be in control and properly positioned during impression making to ensure everything is under control.

True

Impression evaluation involves looking for specific characteristics such as a bevel on the preparation.

True

Hydrophilic impression materials are harder to pour models with compared to hydrophobic materials.

True

Having a hydrophobic impression material can lead to gaps in the final impression due to the way it beads up.

True

Patient comfort techniques play a crucial role in ensuring accurate dental impressions.

False

It is more important to make a good, sharp impression than to pour the model correctly.

False

Using a bubbleizer on a hydrophobic material makes the surface more hydrophobic.

False

It is not important to double-check the occlusal reduction when making an impression.

False

Practicing pouring skills with a surfactant improves one's proficiency in using it.

True

Patient comfort techniques are not relevant when making dental impressions.

False

The speaker emphasized the importance of placing the cord properly while making impressions.

True

The traditional technique for dental impressions involves placing a small piece of cellophane in the tray over the material seated in the mouth.

True

In the traditional technique, after setting the cellophane in the tray, you remove it and have an indent where all the teeth were, but no room around the teeth.

False

The technique of using light body material squished into the mouth against the teeth can potentially displace tissue, blood, and capture the dental impression.

True

One of the techniques mentioned involves grinding out some room in the initial impression to add more wash material.

True

Using light body material in dental impressions is highly recommended by the faculty in the clinic.

False

There are various variations to the traditional technique, including drilling holes in trays and injecting body material around teeth.

True

Materials used for dental impressions come in varying forms, such as different consistencies and compositions.

True

The putty wash technique involves adding putty material to the initial impression without any modifications.

False

Drilling holes in trays and injecting body material around teeth is not considered a valid approach in dental impression techniques.

False

In the traditional technique, the light body material is squished into the mouth against the teeth, displacing tissue and blood to capture the dental impression.

True

The putty wash technique involves adding putty material to the initial impression without any modifications.

False

The putty wash technique involves adding putty material to the initial impression without any modifications.

False

Using light body material in dental impressions is highly recommended by the faculty in the clinic.

True

Hemostatic agents are crucial in dental impression techniques to control bleeding and ensure clear impressions.

True

Using light body material in dental impressions is highly recommended by all faculty members in the clinic.

False

In dental impression techniques, drilling holes in trays and injecting body material around teeth is considered a valid approach.

False

Injecting body material around teeth is not considered a valid approach in dental impression techniques.

False

Hemostatic agents are commonly used in traditional dental impression techniques to improve impression accuracy.

False

It is recommended to box the impression when first using new materials in dental impression techniques.

False

The PVS material used in dental impressions is different from vinyl polyester.

False

A regular or heavy body material is mixed using an auto mixing machine in dental impression techniques.

True

The auto mixing gun is used to inject heavy body material during the dental impression process.

False

The machine used for mixing heavy body material in dental impressions usually has a timer built into it.

True

Using light body material in dental impressions is not recommended by the speaker in the passage.

False

The putty wash technique involves removing putty material from the initial impression and adding a different material for modifications.

False

Hemostatic agents are irrelevant in the context of dental impression techniques according to the passage.

False

Heavy body material is typically mixed using a machine with a built-in timer for precise mixing.

True

The speaker emphasizes the importance of using heavy body material over light body material for better dental impressions.

False

The putty wash technique involves modifying the initial impression before adding putty material.

False

Hemostatic agents are commonly used in traditional dental impression techniques to improve impression accuracy.

True

Patient comfort techniques are irrelevant when making dental impressions.

False

According to the passage, the key thing to watch out for when using disposable syringes is that they are often manufactured poorly, resulting in plastic bits at the end.

True

In dental impression techniques, it is recommended to spread separate groups of materials around a pad for efficient mixing.

False

If light body material has been in the mouth for too long, it may lead to an inaccurate impression.

True

In dental impression techniques, placing the catalyst directly on the base is considered a correct method for ensuring a good impression.

False

Using a heavy body material with a timer built into the mixing machine is recommended for making precise dental impressions.

False

Using a hydrophobic impression material can lead to gaps in the final impression.

True

The putty wash technique involves adding putty material to the initial impression without any modifications.

False

It is highly recommended by the faculty to use light body material in dental impressions.

True

Hemostatic agents are crucial in dental impression techniques to control bleeding and ensure clear impressions.

True

Heavy body material is used for precise and detailed impressions in dentistry.

True

The finish line should have bubbles and gross voids to ensure a good impression.

False

The traditional technique involves drilling holes in trays and injecting body material around teeth.

False

Patient comfort techniques play a crucial role in ensuring accurate dental impressions.

True

The putty wash technique involves capturing the entire finish line and some uncut tooth beyond it all the way around.
