Definitions

  • the present invention relates to a high speed stylus, low speed stylus, dental micromotor dental turbine drive system which provides for the turbine to be fluid driven, considerably reducing the noise levels produced by the said pen when in operation.
  • the daily dental surgeon in addition to having to deal with problems inherent to the handling of dental equipment, is subject to noise exposure in his work environment, especially the noise from the equipment that make up a dental office, especially those produced by the dental office. by dental turbines, widely used in a dentist's routine.
  • Such dental turbines operate through compressed air, ranging in the range of 230,000 rpm to 450,000 rpm, and the average values of sound intensity levels range in the range of 70 to 90 decibels.
  • the maximum noise level allowed by the World Health Organization is 80 decibels when the worker is exposed for up to 8 hours per day.
  • MU 8500878-8 refers to a constructive arrangement introduced in a dental pen based on the use of a plumbing output of air and noise and a mechanical assembly that produces less vibration.
  • the dental pen in question has in its internal structure a bearing assembly differentiated from the conventional assembly used in models known in the state of the art.
  • This differential bearing assembly is formed by balls interspersed with other smaller diameter balls, which are supported by appropriate supports between the pen head and the air turbine. Smaller diameter balls serve as separators and replace conventional bearing separators, and through the low clearance between the interleaved balls, when the turbine is running, sliding and rotating direction can be achieved on the larger balls with minimal of possible noises.
  • Another innovative feature presented by the dental pen of the present utility model patent is the presence of an exhaust vent, excess lubricants and debris that may accumulate inside the dental pen.
  • This channel is present in the air outlet of the pneumatic turbine and is coupled to a piping that has the function of taking air to a remote location relative to the workplace. Because sound easily propagates through the air, this channel significantly decreases the noise level emitted by the dental pen and transports air and turbine-generated noise, spheres and other mechanical components out of the workplace.
  • PI0405309-5 which describes an integrated ergonomic intelligent dental system for application in dental-oral and prosthetic surgical acts, which is intended to eliminate occupational disability factors. It consists of three interdependent modules, namely: Ergonomic module of direct manual actuation in surgical, tooth-oral and prosthetic acts, which are high-speed and low-speed motors, which are called: 'dental pens', which It is installed, fixed in the body of the dental pen, being equipped with sensors and internal electronic commands, submitted to external control, through digital movements of professionals; Electronic central control module and Electronically driven and controlled electro-pneumatic on-off valve module (via the ergonomic module), or even a single proportional electropneumatic valve actuated and controlled by the ergonomic module.
  • Ergonomic module of direct manual actuation in surgical, tooth-oral and prosthetic acts which are high-speed and low-speed motors, which are called: 'dental pens', which It is installed, fixed in the body of the dental pen, being equipped with sensors and internal electronic commands, submitted to external control, through digital movements
  • the modules are interconnected through their electronic, electrical and pneumatic devices and circuits.
  • This system like the others Existing dental systems, equipment, chairs have compressed air as the kinetic energy source to drive their high-speed turbine as well as their low-speed turbine.
  • This Patent has the purpose of solving the serious problems pointed out herein by eliminating the sources of RSI 'Repetitive Strain Injury', or rather by eliminating the sources of DORT 'Osteomolecular Disorders Related to Work', namely , eliminating 'the pedal, the crankset', which will no longer exist, being replaced by the innovative Ergonomic Module, installed in the body of the dental pen, which is triggered and controlled by digital movements by professionals.
  • Radio frequency remote control where all commands, pneumatic controls will be live (synthesized), thus replacing not only the foot pedals, as well as the digitized commands.
  • the features described in the ergonomic and integrated intelligent dental system differ entirely from the concept of the present invention in that it is based on the replacement of conventional dental equipment controls with remote controls. Additionally, this system does not suppress noise produced by the dental turbine.
  • the present invention relates to a high-speed pen, low-speed pen, dental micromotor type dental turbine drive system comprising a fluid source or liquid reservoir connected to a pressurized pump connected to a A source of electrical power or battery, where when the dentist depresses the pedal, the pump automatically injects fluid under pressure into a fluid channel to drive the dental turbine.
  • the main object of the present invention is to provide a considerable reduction of the noise level within a dental office by driving the dental turbine through fluid.
  • Another objective is to decrease the incidence of hearing problems in professionals working in a dental office.
  • Another objective is to increase the rotation of the dental turbine drill.
  • one or more embodiments comprise the aspects to be described below and specifically defined in the claims.
  • the following description and the accompanying drawings provide certain illustrative details of aspects of the embodiments described. These aspects, however, indicate only some of the many ways in which the principles of various modalities can be used.
  • the embodiments described are intended to include these aspects and their equivalents.
  • Figure 1 illustrates a schematic view of the dental turbine drive system object of the present invention.
  • the present invention relates to an ODONTOLOGICAL TURBINE DRIVING SYSTEM, which provides a considerable reduction of the noise level within a dental office.

  • the noise reduction of the dental turbine (1) is due to the fact that the turbine drive is made by fluid that stifles the propagation of sound. In cases where the turbine is driven by the high-pressure airstream produced by the air compressor, the sound produced by the balls and other mechanical components travels easily through the air.
