Short Drills Set

Short Drills Set

Product Description

The Short Drills Set is a reusable implantology surgical instrument kit intended for standard implant osteotomy preparation and installation of two-stage dental implants in clinical situations with limited surgical access.

The set includes:

- Marking Bur (403419)
- Short Cylindrical Drills with diameters: 2.0 mm, 2.8 mm, 3.2 mm, 3.65 mm, 4.2 mm with external or internal cooling (401120, etc.)
- Hex Key with 2.43 mm hexagon “Standard Platform” (430525 – short manual)
- Hex Key with 1.27 mm hexagon for screws (431112 – short manual)
- Short Ratchet Wrench (446300)

The system is designed for preparation of the implant bone bed and installation of two-stage dental implants with lengths from 6.0 mm to 11.5 mm and diameters from 3.0 mm to 5.0 mm within the DMi implant system (UTI, PRTI, UMI, PMI).

The Short Drills Set is particularly suitable for use in posterior regions of the upper and lower jaw and in clinical situations involving limited mouth opening.

Manufactured from medical-grade stainless steel, the instruments provide excellent dimensional precision, cutting efficiency, corrosion resistance, mechanical durability, and long-term clinical reliability.

Intended Use

The Short Drills Set is intended for:

- Standard implant osteotomy preparation
- Installation of two-stage dental implants
- Implant surgery in posterior jaw regions
- Implant procedures with limited mouth opening
- Bone bed preparation for DMi implant systems
- Oral implantology procedures

Indications for Use

1. The instruments are indicated for use in dental implant surgical procedures requiring controlled bone preparation and placement of two-stage dental implants with internal hexagon H2.43 mm connection systems.

2. The instrumentation is compatible with implant systems using an internal hexagon of 2.43 mm for implants with lengths of 6.0 mm, 7.0 mm, 8.0 mm, 10.0 mm, and 11.5 mm.

Contraindications

The Short Drills Set is not intended for:

- Implants with length 13.0 mm and greater
- Narrow diameter implants 3.0 mm and 3.3 mm
- One-piece implants
- Zygomatic implants

Do not use the instruments:

- If the instruments are damaged, bent, worn, or corroded
- Without proper sterilization before clinical use
- At rotational speeds exceeding recommended operating limits

Warnings

- The instruments must be used only by qualified dental professionals trained in implantology procedures.
- The packaged medical device is supplied non-sterile and must be sterilized before use.
- The drills should be replaced when cutting efficiency decreases.
- Recommended drill replacement interval: after 30–50 drilling procedures.

 Reduced drill cutting efficiency may result in:

- Bone overheating
- Bone fracture
- Implant rejection
- Drill fracture
- Jawbone cracks or chipping
- Severe postoperative pain
- Increased postoperative edema

Precautions

- Sterilize all instruments before first use and before each subsequent use.
- Use copious sterile saline irrigation during drilling procedures.
- Use intermittent drilling technique during osteotomy preparation.
- Inspect all instruments before each use for wear, deformation, or damage.
- Follow standard implantology surgical protocols and implant manufacturer recommendations.
- Clean instruments immediately after use to prevent residue accumulation.

Directions for Use

- Preparing the Short Drills Set
- Verify that all instruments are present in the surgical kit.
- Check drill sharpness and cutting efficiency.
- Clean and disinfect the instruments according to approved clinical protocols.
- Sterilize all instruments before use.

Cleaning Procedure

- Soak instruments in 3–6% hydrogen peroxide solution for 20 minutes.
- Rinse in running distilled water for 3–5 minutes.
- Perform ultrasonic cleaning in distilled water at 60–70°C for 20–30 minutes.
- Soak in approved medical disinfectant solution for 30 minutes.
- Rinse again in running distilled water for 3–5 minutes and dry completely.

Sterilization Procedure

- Surgical kits and instruments are sterilized using steam sterilization.
- Sterilization agent: saturated water vapor under pressure.
- Recommended sterilization temperature: 135°C (274°F)
- Sterilization cycle: 15 to 180 minutes depending on sterilization protocol.

Surgical Procedure

Bone Preparation

1. Mark the bone using the round bur (403419) to a depth of 2–3 mm.
2. Prepare the osteotomy using the 2.0 mm drill (401120).
3. After drilling to a depth of 8 mm, insert the titanium depth gauge (451630) or shortened titanium depth gauge (451030).
4. Perform radiographic examination using periapical or panoramic imaging.
5. Evaluate implant positioning, drilling depth, and parallelism before continuing osteotomy preparation.

The implant bed should be prepared sequentially using drills of increasing diameter with continuous irrigation and intermittent drilling technique.

The last drill should be 0.5 mm smaller than the implant diameter.

Implant Placement

The implant is installed using:

- 2.43 mm Allen key (430525, etc.) for implants with internal hexagon H2.43 and CH2.43 connections
- 2.1 mm Allen key (430521, etc.) for implants with CH2.1 connections

The keys include orientation edges and reference markings for implant positioning and insertion depth control.

Prosthetic Closure Options

Two-Stage Implantation

- Install the cover screw using the 1.27 mm Allen key (431112, etc.).

One-Stage Implantation

- Install the healing abutment immediately after implant placement using the 1.27 mm Allen key (431112, etc.).

Cleaning and Disinfection

Immediately after use:

- Remove visible debris and biological contaminants.
- Rinse thoroughly under running water.
- Clean manually or using an ultrasonic cleaner with approved medical instrument detergent.
- Dry instruments completely before sterilization.

Storage

- Store in a clean, dry environment.
- Protect from moisture and contamination.
- Store in sterilization packaging until use.
