PIROP Biometric scanner ( G-scan )


State-of-the-art  ultrasonic device PIROP in intraoral application for biometry soft tissue thickness in the periodontium (Gingival Thickness) – GUM/Gingiva – Periodontal Soft Tissue biometrics.

PIROP allows to measure and monitor  periodontal mucosa thickness in prophylaxis and periodontal treatment. Identification of a periodontal biotype  has a fundamental meaning in optimal planning of preventive and therapeutic management mainly in periodontology, orthodontics, implantology and dental prosthetics.

PIROP user’s interface based on touch screen technology makes operation easy and user-friendly.

Undoubted advantages of using the Pirop device to measure the mucosa thickness  are  fast measurement, very high accuracy and  a complete  noninvasiveness during an ultrasonic examination.



  • In-point, automatic measurement with automatic averaging and calculation of standard deviation
