Engaging undercuts is considered the least pertinent in denture construction for improving fit. In denture fabrication, the primary concern is creating a stable and secure fit that enhances the retention of the prosthesis. While undercuts can help retain the denture in certain situations, their engagement can sometimes compromise the ease of insertion and removal of the denture.

In contrast, maximizing ridge contact is crucial as it directly influences how well the denture adheres to the supporting structures of the mouth, providing optimal stability and comfort for the patient. Maintaining aesthetic contour also plays an important role, as it affects the overall appearance and natural look of the denture, directly impacting patient satisfaction and confidence. Furthermore, prioritizing patient comfort is essential, as any discomfort can lead to a lack of cooperation and potential problems with denture wear. Therefore, while undercuts can assist in retention, they are not as vital to achieving overall fit compared to the other factors mentioned.
