Intended Use

Dental Low-speed Turbine Handpiece is intended for removing carious material, excess filling material, cavity and crown preparation, finishing tooth preparations and restorations, root canal preparations and polishing teeth.

Device Story

Dental Low-speed Turbine Handpiece is an air-powered instrument used by dental professionals in clinics or hospitals for drilling, grinding, and repairing tooth disease. The device consists of a handpiece, connector, air motor, and geared angle handpiece. It operates via air pressure (245–392 KPa) to drive rotation at speeds up to 22,000 rpm. The device features a slide-proof handle and various gear ratios (1:1, 20:1, 1:5) to facilitate operational vision and efficiency. It requires routine maintenance with specified lubricant (PANA SPRAY Plus) and is compatible with steam autoclave sterilization at 135°C. The output is mechanical rotation for dental procedures, allowing the clinician to perform precise tooth preparation and restoration tasks, ultimately benefiting the patient through effective treatment of dental conditions.

Clinical Evidence

Bench testing only. Performance testing conducted per ISO 14457; biocompatibility testing per ISO 10993-1; reprocessing and sterilization validation per ISO 17665:2006 and ISO 11134:2003. No clinical data provided.

Technological Characteristics

Materials: Stainless steel, brass, titanium. Energy source: Air-powered. Dimensions/Form: Handpiece with air motor and geared angle attachments. Connectivity: None. Sterilization: Steam autoclave (135°C). Standards: ISO 14457, ISO 10993-1, ISO 10993-5, ISO 10993-10, ISO 17665, ISO 11134.
