Steam autoclave sterilization is the most widely used method for reprocessing intraoral scanner tips. Selecting the correct temperature and cycle time is important for both effective sterilization and tip longevity.
Two Standard Autoclave Cycles
| Parameter | Cycle A (Standard) | Cycle B (Rapid) |
|---|---|---|
| Temperature | 121 °C | 134 °C |
| Pressure | 102.9 kPa (gauge) | 205.8 kPa (gauge) |
| Sterilization time | 30 minutes | 4 minutes |
| Drying time | 30 minutes | 30 minutes |
| Best for | Routine use, gentler on tip life | High-volume clinics needing fast turnaround |
How to Choose
Daily / routine use → Prefer the 121 °C / 30-minute cycle.
Lower temperature reduces thermal stress on optical components and seals, helping extend tip service life.
Short patient intervals or limited tip inventory → The 134 °C / 4-minute rapid cycle can be used.
Faster turnaround is useful, but repeated high-temperature exposure may accelerate aging of lens adhesives and seals over time.
Drying for 30 minutes is mandatory in both cycles. Residual moisture can compromise optical performance.
Recommended Autoclave Procedure
Complete thorough pre-cleaning and drying of the tip according to the manufacturer's protocol.
Insert medical gauze into the front of the tip to protect the optical window from direct steam and packaging friction.
Place the tip in a dedicated sterilization pouch, seal it, and label with date and cycle count.
Load into the autoclave and select the appropriate validated cycle.
After the cycle finishes, wait until pressure returns to zero and the tip cools to room temperature before removal.
Check the chemical indicator on the pouch to confirm successful sterilization.
Inspect the optical window for cracks, fogging, or coating damage.
Record the sterilization cycle and replace the tip when the manufacturer's maximum cycle limit is approached.
Brand-Specific Examples (Always Verify with Official Manual)
Shining 3D Aoralscan tips: typically support 121 °C / 30 min or 134 °C / 4 min; maximum around 100 cycles.
Fussen Linglong 5: rated for up to 150 autoclave cycles.
Medit i-series: follow manufacturer-recommended parameters (often the rapid 134 °C cycle).
3Shape TRIOS: tips are autoclave-compatible; exact parameters are listed in the user manual.
Some tips from certain brands support only high-level chemical disinfection and are not autoclave-compatible - always check the official instructions.
Common Mistakes to Avoid
Autoclaving without proper pre-cleaning (organic residue can bake onto the lens).
Using the tip immediately after sterilization (risk of patient burns and temporary optical distortion from residual heat/moisture).
Continuing to use a tip beyond its rated cycle count (accuracy and seal integrity decline).
Over-tight packaging that compresses the tip.
Mixing tips from different brands or models that have different validated parameters in the same load.
Always follow the exact sterilization parameters and maximum cycle count published by the manufacturer of your specific tip. Aident AI-30 series tips are designed for reliable clinical performance when reprocessed according to the official care guidelines supplied with the device.
