The Xdent PT-XD Scaler & Air Polisher integrates ultrasonic periodontal treatment and air-powered sandblasting into a unified, high-performance workstation. Utilizing piezoelectric ceramic technology, the scaler operates with an elliptical vibration trajectory that disperses contact forces evenly between the working tip and tooth surface. Coupled with real-time dynamic frequency tracking, the system automatically adapts to tip characteristics to maintain optimal performance across scaling, periodontal, and endodontic procedures.

For air polishing, the unit features a 0.7 mm small-caliber gingival sandblasting handpiece engineered with a high-coaxiality water-vapor design. The inner stream delivers compressed air and powder to eradicate stubborn stains, plaque, and soft deposits, while the concentric outer water ring encapsulates the powder spray to minimize overspray, rinse the field, and protect soft tissues from abrasive damage.

Designed for clinical versatility and convenience, the Xdent PT-XD features a dual waterway supply capable of delivering water or clinical solutions such as chlorhexidine and sodium hypochlorite from clearly graduated bottles. Its built-in heating valve provides automatic water preheating to minimize patient sensitivity. Smart magnetic induction automatically detects the active handpiece and applies preset power and water levels, while automated 15-second pipeline purge cycles prevent powder clogs, fluid stagnation, and internal corrosion.

Key Features

0.7 mm Caliber Gingival Sandblasting Handpiece: Concentrated nozzle with high-coaxiality fluid dynamics encapsulates powder inside an outer water barrier, reducing aerosol spread and protecting soft tissues and enamel.

Elliptical Vibration Trajectory: Piezoelectric ceramic drive creates smooth, elliptical tip motion to disperse impact forces and enhance treatment comfort.

Real-Time Dynamic Frequency Tracking: Automatically monitors tip load and adjusts operating frequency ($30\pm5\text{ kHz}$) to ensure maximum cutting efficiency.

Comfort Temperature Control System: Self-developed internal heating valve with touch-panel control and automatic preheating ensures temperature-controlled irrigation to reduce dentin sensitivity.

Magnetic Induction Recognition: Automatically identifies whether the scaling or sandblasting handpiece is lifted, instantly engaging the appropriate preset power and water settings.

Automated Pipeline Cleaning: Includes dedicated 15-second automated purge cycles—clearing powder residue in air polishing mode to prevent blockages and flushing liquids in scaling mode to prevent internal corrosion.

Dual Waterway & Medicament Support: Clear-scale reservoir supports specialized clinical irrigants including chlorhexidine and sodium hypochlorite.

Titanium Alloy Working Tips: Tip hardness (HRC 37–43) is lower than tooth enamel (HRC 50), offering superior elasticity, reduced scratching, and gentle debridement.
