Essential Trimming RulesControl the speed: Keep your handpiece at a low to medium speed (around 10,000–15,000 RPM) to prevent friction heat.Choose the right bur: Avoid standard acrylic or metal carbide burs. Use specialized tools like ceramic zirconia trimmers or sharp green stones.Use light pressure: Let the bur shave the material gently instead of forcing it into the denture.Prevent fraying: If nylon fibers or fuzz develop on the edges, switch to a fresh, sharp bur or a fine-grit point to cleanly shear the material.Step-by-Step Adjustment WorkflowLocate sore spots: Mark areas causing tissue irritation using pressure-indicating paste (PIP) in the patient's mouth.Contour bulk areas: Use a flame-shaped or tapered ceramic stone to reduce long borders or thick flanges.Smooth edges: Round off sharp trimmed margins using a slow, sweeping motion with a round or conical finishing bur.Polish the surface: Finish the adjusted area with a soft rubber silicone wheel or a specialized flexible denture polisher to restore a smooth feel without scratching. Avoid traditional wet pumice wheels.
