The removal of old dental crowns should be performed by a dental professional using specialized tools, such as a crown remover or high-speed handpiece with a diamond or carbide bur, to break the cement seal and loosen the crown without damaging the underlying tooth structure. The process typically involves several steps, including administering local anesthesia, using controlled pressure to loosen the crown, and carefully cleaning the underlying tooth structure after removal 1. For all-ceramic crowns, an Er:YAG laser can be used to efficiently debond the crown without damaging the underlying tooth structure, with an average debonding time of 190 seconds for E.max CAD crowns 2.
When removing old dental crowns, it is essential to prioritize preserving as much sound tooth structure as possible to prevent tooth fractures 3. The use of full coverage and minimizing the removal of sound tooth structure are crucial factors in preventing tooth fractures 3. Additionally, the placement of crowns to prevent tooth fracture should be carefully determined to ensure effectiveness and appropriateness 4.
Some key considerations when removing old dental crowns include:
- Using specialized tools to break the cement seal and loosen the crown
- Applying controlled pressure to avoid damaging the underlying tooth structure
- Cleaning the underlying tooth structure after removal
- Preserving as much sound tooth structure as possible to prevent tooth fractures
- Using alternative removal techniques, such as Er:YAG laser, for all-ceramic crowns.
It is also important to note that the removal of old dental crowns should only be performed by qualified dental professionals with appropriate tools and expertise to ensure the best possible outcome for the patient's oral health and quality of life.
