Selected models provide torque capacity of up to 80 Ncm and a maximum rotational speed of up to 2,000 min⁻¹. Clinicians should follow the implant-system protocol, motor settings and bur or drill manufacturer instructions.

4:1 Reciprocating Contra-Angle Handpieces

Kaneiko 4:1 reciprocating contra-angle handpieces convert motor rotation into controlled reciprocating movement.

They are designed for use with compatible reciprocating instruments in procedures such as:

• Interproximal reduction
  
• Contact-area finishing
  
• Orthodontic refinement
  
• Controlled enamel reduction
  
• Polishing and contour correction
  

The selected strip, file or reciprocating instrument must be compatible with the handpiece system and intended clinical procedure.

Dental Quick Couplings

Kaneiko dental quick couplings provide the connection between compatible high-speed handpieces and the dental unit hose.

Available configurations include systems compatible with:

• KaVo®
  
• NSK®
  
• Bien-Air®
  
• Sirona®
  
• W&H®
  

Depending on the coupling model, functions may include air transmission, water delivery, exhaust management and fibre-optic light transfer.

Before purchasing, dentists should verify the handpiece connection, hose configuration, number of holes and lighting requirements. A coupling that looks similar may not be mechanically or functionally compatible with another system.

Dental Air Motors

Kaneiko dental air motors power compatible low-speed contra-angle and straight handpieces.

Selected models provide:

• Forward and reverse rotation
  
• Fibre-optic light transmission
  
• Adjustable operating control
  
• Compatibility with low-speed contra-angle and straight handpieces
  

Dental air motors are suitable for finishing, polishing, trimming and other low-speed procedures. Electric contra-angle handpieces should instead be connected to a compatible electric micromotor system.

Kaneiko and MR.Bur Bur Bundles

Kaneiko bur bundles combine compatible handpiece systems with selected MR.Bur dental burs for procedure-based workflows.

Available bur selections may support:

• Crown and bridge preparation
  
• Cavity preparation
  
• Veneer preparation
  
• Restorative cutting
  
• Finishing and polishing
  
• Surgical procedures
  
• Interproximal reduction
  
• Laboratory adjustment
  

Matching the correct bur shank with the correct handpiece is essential. High-speed handpieces generally use FG burs, low-speed contra-angle handpieces use CA burs, and straight handpieces generally use HP burs.

Supporting Modern Dental Workflows

Kaneiko products are organised into specialised collections so dentists can identify the handpiece system required for a specific procedure.

High-speed handpieces support rapid cutting during crown preparation, cavity preparation and restorative procedures. Low-speed contra-angle and straight handpieces support finishing, polishing, trimming and prosthetic adjustment.

Electric contra-angle handpieces provide controlled speed-increasing performance for restorative preparation. Surgical and implant contra-angle handpieces support procedures requiring controlled torque, access and irrigation. Reciprocating handpieces provide specialised movement for compatible interproximal reduction and finishing instruments.

Quick couplings and air motors complete the handpiece connection system, while bur bundles help clinicians select rotary instruments for the intended clinical workflow.

Built Around Daily Clinical Requirements

Dental professionals use handpieces repeatedly throughout the working day. Product selection should therefore consider more than maximum power or rotational speed.

Important clinical considerations include:

• Head size and posterior access
  
• Bur compatibility
  
• Chuck security
  
• Water spray pattern
  
• Fibre-optic or LED visibility
  
• Noise and vibration
  
• Motor or coupling compatibility
  
• Sterilisation requirements
  
• Cartridge or maintenance design
  
• Intended procedure
  

Kaneiko presents model-specific specifications so clinics can compare products according to their clinical and equipment requirements.

Product Compatibility and Maintenance

Correct compatibility is essential for safe and predictable handpiece operation.

Before using a Kaneiko product, confirm:

• The handpiece-to-motor or handpiece-to-coupling connection
  
• The required bur shank
  
• Maximum operating speed
  
• Irrigation configuration
  
• Lighting compatibility
  
• Sterilisation instructions
  
• Lubrication and maintenance requirements
  

Maintenance is model dependent. Serviceable handpieces should follow the lubrication, cleaning and cartridge instructions provided for that product.

Kaneiko integrated high-speed models with fixed M4 connections are different. These economical, non-serviceable handpieces should not be lubricated, dismantled or internally repaired. A faulty integrated handpiece should be removed from use and replaced.
