The NiTi Perio Saw® is supplied as four tip shapes, individually or as a set of four. This page collects, in one place, how the instructions for use (IFU) match each tip to a tooth position and how the instrument is reprocessed between procedures. It is written for the whole surgical team – in a veterinary practice that includes the veterinary nurses and technicians who prepare and reprocess instruments, and in a dental practice the dental nurses and assistants who do the same. The reprocessing conditions below are quoted from the veterinary edition of the IFU; the human dental edition has its own IFU, which is supplied with that instrument.
Four tips by tooth position
| Tip | Model code | Intended position (IFU) | Working tip length |
|---|---|---|---|
| Straight | NiTi Periosaw-ST-02 | Anterior teeth | 36 mm |
| Curved | NiTi Periosaw-CD-02 | Canine or premolar | 36 mm |
| Angled | NiTi Periosaw-AD-02 | Mesial and distal | 42 mm |
| Flat angled | NiTi Periosaw-FA-02 | Interproximal | 42 mm |
All tips share a 100 mm stainless-steel handle (SUS304, ASTM A276) and a nickel-titanium shape-memory alloy tip (ASTM F2063) with a micro-serrated edge [1]. The suffix -02 denotes the 2 mm tip width [1]. As with other extraction instruments, the instrument should suit the root it is used on [2].
Before each use
The IFU checklist [1]: confirm that the patient has no known reaction to, or incompatibility with, nickel or titanium; check the package for breakage; inspect the instrument for damage, breakage, deformation or foreign material; sterilise it as below; and read the IFU. Do not use a damaged, bent or contaminated instrument. The recommended operating-room temperature is 15–30 °C [1].
Sterilisation
The instrument is supplied non-sterile and must be sterilised before first use and before every later use [1].
| Method | Configuration | Temperature | Exposure | Drying |
|---|---|---|---|---|
| Autoclave | Wrapped (sterilisation pouch or wrap) | 134 °C | 15 minutes | 20 minutes |
Keep it in the pouch or wrap until use [1].
Cleaning after use
Remove blood and debris under running water with a cleaning brush; clean with an instrument washer and instrument detergent following their manufacturers' instructions; dry with a clean cloth or a dryer; inspect again for damage, deformation and foreign material; then pack and sterilise [1]. General veterinary dental guidance likewise expects dental instruments to be cleaned, inspected and steam-sterilised in packs [3].
Storage and retirement
Store at 15–30 °C and 1–75 % humidity, away from sunlight, with nothing loaded on top of the package [1]. The IFU gives no sharpening procedure: the micro-serrated nickel-titanium edge is not resharpened. Retire a tip that is worn, damaged or deformed and dispose of it as sharp metal clinical waste under local rules for clinical waste [1].
Who does what in the clinic
The veterinary IFU limits use to veterinarians and trained veterinary staff [1]; the human dental edition is for dentists. Who may perform extractions differs by country – in the United Kingdom, for example, see the RCVS guidance on delegation to veterinary nurses [4] – so nurses, technicians and assistants should follow their national rules. Preparing the pack, reprocessing and inspection are typically shared by the team; this guide covers those tasks, not extraction technique. For technique, see Cutting the periodontal ligament in dog and cat extractions.
