Software to control vibration

Abstract

A processor containing software allowing for measuring the speed of a motor, and adjusting that speed by pulse width modulation is provided. A dedicated voltage limiter prevents excess speed, and a battery charge management controller to charge the battery and monitor the battery charge status, ensures battery voltage is regulated to 3.3 V. These additional features contribute to safety, such that when included on an orthodontic remodeling device they allow safe and effective vibration, with minimal changes in frequency and force and no danger of excess speed or power.

AI Technical Summary

Benefits of technology

[0039]Preferably, a custom or semi-custom application-specific integrated circuit (ASIC) is designed to drive the device, and is particularly preferred for a completely intraoral device. An ASIC can include entire microprocessors, memory blocks including ROM, RAM, EEPROM, Flash and other large building blocks. Such an ASIC is often termed a SoC (system-on-chip). Hardware description language (HDL), such as Verilog or VHDL, can be used to describe the functionality of ASICs. Field-programmable gate arrays (FPGA) are another option for driving the device. Programmable logic blocks and programmable interconnects allow the same FPGA to be used in many different applications. For smaller designs and / or lower production volumes, FPGAs may be more cost effective than an ASIC design even in production.

[0079]When we refer to contacting “the teeth” or similar phrase herein, what is meant is the entire dentition, e.g., the teeth of both arches. If less than the entire dentition is intended, it will be referred to as maxillary teeth, mandibular teeth, or a “portion” of the teeth or specific teeth or arches will be identified by name. Nevertheless, the bite plate need not contact every single tooth, since by definition some malocclusions may results in one or more teeth considerably out of alignment. The phrase also allows some leeway at the molars to accommodate the fact that dentition varies in size, and that molars erupt over 20-25 years of age, if at all, or may be removed to provide additional space for the remaining teeth, and thus most patients will not have a full set of adult teeth. Therefore, a bite plate intended to contact all teeth of the average youth patient, may not reach the molars of older or larger patients, or patients with more mature dentition.

Problems solved by technology

Any variation therefrom results in malocclusion.

Orthodontic treatment is complicated by the fact that it is uncomfortable and / or painful for patients, and the orthodontic appliances are perceived as unaesthetic, all of which creates resistance to use.

Further, the 24-month treatment time is very long, and further reduces usage and compliance, which can include chronic poor dental hygiene.

However, this idea did not become practical until the advent of 3D scanning and computer modeling in 1997.

However, because these appliances can be removed, compliance can be an issue, and failure to use slows overall treatment time.

As a treatment modality, aligners are also limited in the classifications of clinical malocclusion that they can address.

In the past, aligners have not been able to easily rotate or extrude teeth because the aligner cannot adequately direct force in all directions.

However, Mao's early experiments were performed on rabbit cranial suture closure model, and no device was ever built that could be used for human teeth.

However, no such device was available.

Finally, the device is slim, capable of hands free operation, lacks the bulky head gear of the prior art devices, and has optimized force and frequency for orthodontic remodeling.
