ProsthodonticsGuiding planes are flat, polished surfaces on the abutment teeth that guide the RPD into place. They are crucial for the predictable placement of retentive elements such as clasps and for ensuring that the forces are transmitted along the long axis of the teeth, minimizing horizontal movements. Additionally, they help in the overall stability and function of the denture.

PhysiologyGastric chyme, which is the mixture of food and gastric juice, is highly acidic due to the presence of hydrochloric acid secreted by parietal cells. The pH typically ranges from 1.0 to 2.0 when it enters the duodenum. This acidity helps to denature proteins and provides the optimal environment for pepsin activity. Once in the duodenum, the chyme is neutralized by the secretion of bicarbonate from the pancreas and bile from the liver.
