The high survey line is characterized by being positioned in the occlusal third of the tooth in both the near and far zones, which is important for determining the contour of the tooth.

Explanation: Anterior incisal contacts during posterior masticatory functions are not desirable because they can lead to instability and improper function of the complete denture. Ideally, posterior teeth should provide the primary occlusal contacts during chewing, while anterior teeth should not interfere with these functions. This helps maintain a balanced occlusion and prevents excessive wear or damage to the denture.

Which of the following is most likely to occur if attachment epithelium is removed during curettage: deepening of pockets.

The primary purpose of rinsing the alginate impression in a watery mix of gypsum is to remove the residual saliva on the impression.

Explanation: In bilateral balanced occlusion, if the incisal guidance is steep, it is necessary to create a compensating curve that is also steep to maintain balanced occlusion during lateral movements. This helps to ensure that the occlusal contacts remain balanced and stable, preventing tipping or dislodgment of the denture during function. The other options do not adequately address the need for balance in occlusion.

a properly designed rest on the lingual surface of a canine is preferred because it exerts less leverage against the tooth compared to a rest on the incisal surface (option 1). This is important for maintaining the integrity of the tooth and preventing potential damage or displacement.

 Explanation: The vertical dimension of occlusion (VDO) is easier to establish in patients with removable partial dentures (RPDs) because they typically have some natural teeth remaining. These teeth provide reference points for occlusal relationships and help in determining the appropriate vertical dimension. The presence of remaining teeth allows for better tactile feedback and aids in achieving a more accurate and functional occlusion. The other options, while they may have some relevance, do not directly contribute to the ease of recording VDO as effectively as the presence of remaining teeth.

The thickness of the spacer used in a special tray is 2.0 mm.

Explanation: The compensating curve is designed to ensure that occlusal contacts are balanced during protrusive movements, which is essential for maintaining stability and function of the complete denture. This curve helps to distribute occlusal forces evenly and prevents tipping or dislodgment of the denture during functional movements. The other options do not accurately reflect the primary purpose of the compensating curve.
