6. Our Firm and its Characteristics

7. Tools: Five S
1. Sort the useful from the useless
3. Clean, wash and sterilize
2. Set in order, a place for everything
and everything at its place
4. Standardize (regular flow of
the previous three points)
5. Discipline intended to
sustain over time the
previous four points.

8. Tools: S.M.E.D
The Dental Surgery firm, moreover, uses the S.M.E.D. technique
(Single Minute Exchange of Die) that has the objective to reduce
the set-up times to allow a different production characterized
by a few lots which follow the pull method.
Basically, in an entire set-up project, the objective is to contain
the time of“machine-stop”

9. Tools: Muda
The minimizations of Mudas (any kind of waste), is guaranteed
by the simple help of operating tools like job descriptions and
briefings of the Dental Surgery.

10. Tools: The Kaizen philosophy
Following the principles of the Lean Organization the Dental
Surgery uses the Kaizen philosophy.
As it is well known, this approach helps to reduce the business
wastes in every form and requires a permanent and
continuous huge improvement (machines, tools, works and
methods), followed by a strong motivation of the staff.

11. Tools: T.P.M.
Another tool we use is the Total Productive Maintenance. This
is one of the main pillars of the Lean philosophy, and identifies a
management technique of the systems that is not limited to
preserve its efficiency but that leads to a productivity rise of the
pillars.
With the term Full/Total we mean a huge involvement of the
staff (coming from every business functions) in the implication
of activities.

Optimization of the yield per hour of an associate dentist
In managing of dental surgery is important to optimize working scheduling in
processing therapies.
The following charts represent the outputs after the modifications in managing of
working hours and in delegating cost-effective therapies, after the application of
Lean philosophy.

Optimization of the yield per hour of an associate dentist
Comparing semesters, production is increased of about 8,000 euros, with minus 27
worked hours in the total amount of the semester. Increasing is given by a yield per
hour of 20 euros more, worked per hour in the period. As you can infer in the chart,
the production of the hygiene category has diminished of about 22,000 euros,
delegating such category to another member of the team, a dental hygienist.
We have optimized the timing of the dental surgeon member of the team,
increasing the work of other more profitable dental categories.

14. The Main Results after the usage of the
Lean Organization and the Final Reflections
The main results can be seen in the following:
1. reduction in timing or preparation and reorganization and
tidying
2. reduction in timing of factual work
3. reduction in using materials
4. reduction and optimization in programmed supplies and
orders
5. correct payment following base-price list
6. optimization and training human resources
7. reduction waiting-times both for patient and for
appointments and waiting room
8. optimization therapy scheduling and reduction of
appointments
9. increasing qualities of work done and professional service
(last, but not least)
