Watch the Technique in Action: Rubber Dam Placement & Prep Techniques
Mastering Rubber Dam Placement for the ADEX Exam
Proper isolation is key to a successful ADEX exam.
Rubber dam placement ensures a dry field, improved visibility, and safer prep for both anterior and posterior teeth.
Dr. Nasiry demonstrates how to isolate teeth effectively while maintaining proper technique.
Anterior Teeth Isolation: Clamp the pre-molars and isolate the front eight teeth for proper access.
Posterior Teeth: Ensure at least one tooth on either side of the prep tooth is rubber dammed.
Quadrant Isolation: For optimal visualization, consider isolating the entire quadrant if possible.
Step-by-Step Guide: Prep Techniques for Class II and Class III Cavities
1. Use the Right Burr
For Class III preps, Dr. Nasiry recommends a 330 burr, which is one millimeter wide at the tip. It allows for precise control and accurate outline form.
2. Start Your Prep Correctly
Begin slightly underneath the contact area and carefully measure depth to avoid over-prepping. Accuracy here ensures proper marginal ridge height and wall placement.
3. Manage Your Matrix Effectively
Place your sectional matrix so the top aligns with the marginal ridge height. Proper placement ensures correct contouring and reduces adjustments later.
4. Know the Walls of Your Prep
Class III: Incisal wall, facial wall, axial wall, gingival floor.
Class II: Identify internal walls that don’t touch the exterior.
Follow the depth requirements: premolars 1 mm from DJ, molars 1.5 mm.
5. Maintain Proper Isolation Throughout
Use fingers or clamps to ensure your rubber dam stays in place and the prep area remains fully isolated during the procedure.
