Description
The Heister Mouth Gag – HEISTER is a mechanical jaw-opening instrument designed to maintain controlled mouth opening during dental and oral surgical procedures. It is commonly used in extractions, minor oral surgeries, pediatric cases, and procedures requiring prolonged intraoral access.
The screw-adjustable mechanism allows gradual and stable opening of the mandible, providing consistent access to the operative field while minimizing operator fatigue. The design ensures controlled expansion without sudden movement, supporting procedural safety and patient stability.
Manufactured from high-quality surgical-grade stainless steel, the Heister Mouth Gag offers durability, corrosion resistance, and reliable performance under repeated sterilization cycles. It is suitable for use in dental clinics, surgical settings, and specialized procedures requiring mechanical mouth support.
Direction to use
Ensure the instrument is sterilized before clinical use.
Position the mouth gag between the upper and lower posterior teeth on one side.
Gradually rotate the screw mechanism to gently increase mouth opening.
Adjust to the required opening while monitoring patient comfort and stability.
Ensure the instrument is securely positioned before beginning the procedure.
After completion, slowly release the screw mechanism to close the mouth gradually.
Remove the instrument carefully.
Clean thoroughly to remove debris.
Disinfect and sterilize according to standard autoclave protocols before reuse.
