150,000+ Unnecessary Movements?


A picture is worth a thousand words. HSP knows that a picture can also show thousands of unnecessary movements, 150,000+ unnecessary movements or motions per year by the dentist and assistant. Unnecessary movements severely limit productivity and greatly increase stress and fatigue. Movements require time.  Time is money!

The inefficiencies of traditional delivery systems

70% of the world’s dentists use a traditional sit-down over-the-patient chair-mounted delivery unit.  This system makes it impossible for the dental assistant to transfer handpieces.  To retrieve a handpiece the dentist is forced to turn their head from the oral cavity, twist their body, extend their arm to retrieve the handpiece, turn back to oral cavity, rotate and position the handpiece, refocus the eyes and then regain procedural concentration.  (Whew! are you tired yet?)  If the dentist is working in the 8 to 9 o’clock position, the range of movements and the number of motions increase even more because the instruments are 180 degrees directly behind the dentist.

Side and rear delivery units, carts and split delivery systems result in even worse inefficiencies and loss of income. Since dentists charge patients by the completed procedure, the longer a procedure takes, the fewer patients or procedures can be taken care of in a day, and income potential is limited again.  Clinical research has shown that a three surface restoration requires 150 to 160 movements in 30 to 40 min. using traditional equipment.

The efficiency of the true transthoracic delivery system

University clinical studies have proven that the only efficient delivery of dynamic instruments is from the transthoracic position.  HSP’s transthoracic delivery unit provides all instruments in a direct line of reach to the oral cavity, eliminating turning, twisting, reaching, refocusing the eyes, and a loss of concentration. Instrumentation is accessible to either the assistant, as recommended for maximum efficiency, or the doctor when working solo.

Accessibility is maintained from the 7 to 12 o’clock positions. This accessibility increases efficiency, productivity and profits because it eliminates unnecessary and wasted motions.  Clinical studies have shown that a three surface restoration requires only 30 to 40 movements, in 12 to 18 min., when:

  • the dentist uses a fully trained assistant,
  • practices true four-handed dentistry,
  • employs the HSP transthoracic delivery system,
  • the correctly designed HSP patient chair,
  • the HSP Alabama mobile cabinet,
  • and correct clinical seating within the properly designed space where all of the ergonomic criteria have been fulfilled.

Conceptual motion analysis: traditional vs. HSP’s transthoracic delivery

Comprehensive time-motion studies and 40 years of real world clinical experience has shown that a three surface restoration requires 150 to 160 movements in 30 to 40 min. using traditional equipment versus only 30 to 40 movements in 12 to 18 min. using the HSP transthoracic equipment.

Recent statistics state that the average dentist works 192 days per year and treats 12 patients per day.  Using traditional sitdown dental equipment, an average of 155 movements and 8 restorative patients a day results in 1,240 movements a day or 238,080 movements a year.  A dentist fully employing the concepts of true four-handed dentistry and using the HSP transthoracic delivery system has been proven to average 35 movements or motions per procedure.  At 8 patients per day this results in 280 movements a day or 53,760 a year. The reduced movements between traditional and HSP transthoracic equipment is over 184,320.  More importantly, most of these movements are reduced to finger, wrist and elbow motions which are  far less time-consuming, fatiguing and stressful than shoulder, neck and back movements required by alternative delivery systems.

The results: efficiency, time-savings and profitability

The reduction of up to 180,000 unnecessary motions and movements improves efficiency and creates procedural time-savings of as much as 50%, enabling the dentist to double production by treating more patients.  The average dentist produced $660,000 in gross revenues in 2010 (32 hours per week 48 weeks per year).  By cutting procedural time, productivity increases from 20%- 100% have been achieved.  This extends potential increases in annual gross revenues from $120,000 to $660,000.

The time saved can be used to either:

  1. see more patients (increasing revenue).
  2. deliver more services per patient (increasing revenue).
  3. work fewer hours.

In summary,  Time is money!
