Wax to the ideal thickness the case requires, not thinner, not thicker. Remember, the thicker the wax up the higher the chances air bubbles will form. Use TCS wax patterns to help achieve proper wax thickness.
Avoid placing the sprues too close to the teeth when possible. Sometimes this causes air bubbles to appear underneath the teeth. Instead, place sprues at the tip end of the wax up.
Choosing shorter teeth and leaving a large space of thick wax up under the teeth is another reason why bubbles occur. These bubbles usually appear underneath the teeth. Be sure to choose longer teeth to avoid this from happening.
Remember, different resins and injection units require different times, temperatures, and pressure. Follow the manufacturer's instructions.
If a case requires a thicker wax-up using a large cartridge will help avoid bubbles from forming.
Applying too much separator, not allowing it to absorb, and/or using dense separators may prevent the material to flow correctly causing air bubbles and leaving unusual marks behind.
Invest with Putty 95 for clean injections and to save time during the finishing stage!

Use TCS Twist Drills for diatorics.
Diatoric holes must be made in a “T” shape that connect in the middle.
