What should be done before trimming teeth on a stone case for an immediate denture?

• A. Measure the length of the teeth
• B. Mark a line 3 mm above the free gingival margin
• C. Evaluate the patient's bite
• D. Polish the case for aesthetics

Answer: (B)

Marking a line 3 mm above the free gingival margin is crucial before trimming teeth on a stone case for an immediate denture. This step ensures that there is an appropriate reference point to maintain the natural appearance and functional aesthetics of the denture. By establishing this line, the clinician can avoid trimming too little or too much, which could result in a denture that does not fit properly or looks unnatural. Furthermore, keeping this measurement in mind allows the technician to account for the reduction of the alveolar ridge that may occur following tooth extraction. This helps in achieving proper gingival contour, which is vital for the overall fit and look of the immediate denture. Aligning the height of the teeth correctly contributes to a more successful and aesthetically pleasing outcome for the patient. While measuring the length of the teeth, evaluating the patient's bite, and polishing the case are important steps in the process of creating an immediate denture, marking the line above the free gingival margin serves as a foundational guideline that directly influences the success of subsequent steps in the fabrication of the denture.
