- Surgical Spacers: These devices are used in various surgical procedures to create space between tissues or organs. Their safety depends on the specific procedure and the surgeon's expertise.
2. Spacers in Construction and Engineering:
- Structural Spacers: These are used to maintain gaps between building materials. They are generally safe when installed correctly and made from appropriate materials.
- Spacer Rings: Used in bearings to reduce friction and wear. They are essential for proper bearing function and are generally safe when used correctly.
3. Spacers in Other Contexts:

- Furniture Spacers: Used to prevent furniture from sticking or scratching. They are generally safe, but ensure they are made from non-toxic materials.
It's crucial to understand the specific context of the spacer you're asking about to determine its safety. Consult professionals like doctors, dentists, or engineers for specific advice on the safe use of spacers in their respective fields.
