Abstract: Ultrasonic dental instruments, inserts, and insert assemblies are provided which include an acoustic transformer and a tip that, in combination, are configured to operate at an operational frequency different from the frequency of resonance of the transducer that drives the combination. As a result, the ultrasonic dental instruments, inserts, and insert assemblies provide improved performance durability by providing improved output stroke ranges over nominal wear lengths between, for example, 2 mm and 3 mm, which results in more durable performance over a longer service life.

Abstract: A training system includes a tool connected to a control module. The tool includes a tip and a grip having two or more force sensing transducers configured to enable determination of sensor force measurement data. The control module receives the sensor force measurement data. The control module includes a storage device configured to store zeroed force data, and a data processing unit including a processor and memory storing instructions that, when executed by the processor, cause the processor to obtain the sensor force measurement data and the zeroed force data; determine, based upon the sensor force measurement data and the zeroed force data, a load force magnitude that is independent of grasp forces; determine whether the load force is within a set range; and, provide a corresponding indication where the load force is within the set range and/or where the load force is outside of the set range.

Abstract: A dental ultrasonic tool configured to connect to a magnetostrictive or piezoelectric transducer of a dental instrument operating in the frequency range between 18 kHz and 50 kHz. The tool includes a tip and a singular surface marking having a minimum width of 0.5 mm disposed on the tip. The tip includes a distal point as a datum. The singular surface marking is spaced-apart from the distal point of the tip and defines at least one edge. The at least one edge is not coincident with a first flexural node of the tip at an operating frequency of the tip. Dental ultrasonic tip wear measurement tools for measuring the wear on a tip are also provided.

Abstract: An ultrasonic instrument includes a tip portion, a transducer configured to convert electrical energy into vibrational energy, an acoustic transformer interconnecting the transducer and the tip portion, and a grip portion disposed at least partially about the acoustic transformer. The grip portion is coupled to the acoustic transformer via a resilient nodal coupling at a nodal region of the acoustic transformer. The resilient nodal coupling is configured to provide rotational and axial stability to the acoustic transformer.

Abstract: The present disclosure relates to structures that are adapted to facilitate the retention, storage, and transport of arrows. In one embodiment of the present disclosure, for example, an arrow retainer is described that includes a resilient portion having a plurality of passageways extending therethrough for retaining a plurality of arrows therein. Each passageway is resiliently expandable upon insertion of an arrow to maintain the position of the arrow. In another embodiment of the present disclosure, for example, an arrow storage device is disclosed that provides an efficient and secure means of storing arrows. The presently disclosed arrow retainer and arrow storage device may be used in conjunction with one another as part of an arrow storage system.

Abstract: An ultrasonic electro-mechanical resonant system and instrument that provides improvements in the design and implementation of a feedback system. The disclosed configuration and orientation of coils enhance the motional or velocity feedback signals while minimizing the effects of transformer coupling. A two coil and a three coil approach is disclosed that takes advantage of non-homogeneous magnetic fields. An asymmetrical arrangement enables velocity signals to be coupled into the coils without requiring additional signal conditioning or capacitive elements.
