Has published 4 books in the field of orthodontics, one about “Stimulotherapy in Orthodontics” (in Spanish)

Gives courses around the world about his MFS philosophy.

Creator of the MFS philosophy: individualized prescription of the brackets and Stimulotherapy devices.

MFS (multifunction system) is a new diagnosis and treatment philosophy in orthodontics based on the codified diagnosis of oral functions. Oral functions normalization with the use of Stimulotherapy devices. A diagnosis protocol used to calculate the individualization of the brackets torques prescription. MFS objectives are aesthetics and/or stability at the end of the orthodontic treatment.



MFS (multifunction system) PHILOSOPHY

1 – CODIFYING ORAL FUNCTIONS: It’s a new concept that gives a number to each function:

  • Breathing
  • Swallowing
  • Masticatory pattern
  • Key factors:
    • Nose collapse
    • Tongue mobility
    • Adenoids hypertrophy
    • Tonsils hypertrophy

Oral functions codification is a diagnostic tool that gives to the orthodontist the possibility to evaluate the level of dysfunction on each patient and re-evaluate –sometime later- his problem and see if the functional problem has resolved or not.

2 – MFS STIMULOTHERAPY: Is the possibility to use stimuli in the orofacial area to promote automatized exercises to correct oral dysfunctions. A stimulus sensed an afferent sensitive signal to the thalamocortical area of the brain and this response with an efferent motor signal to the muscles around the stimuli.

3 - MFS STIMULOTHERAPY DEVICES: developed to create stimuli during his night time use and promote continuous reflex exercises of the muscles, helping to normalize the oral functions. There are different MFS Stimulotherapy devices:

  • Nose stimulator
  • Mouth obturator
  • Lips stimulator
  • Musculature relaxant
  • Bite plane
  • Ant-bruxism device
  • Open bite device

They work to treat: mouth breathing, nose collapse, snoring, help apnea, lips incompetency, short upper lip with a gummy smile, perioral muscular contraction, bruxism, deep bite, open bite and to protect fixed mechanics from the muscular pattern and promote a faster action of the mechanics…

4 – MFS OCCLUSAL DIAGNOSIS: based on the occlusal analysis and calculating anterior, lateral and posterior discrepancy. Also using a protocol to calculate the stable position of the lower incisors.

5 – MFS CUSTOMIZED BRACKETS PRESCRIPTION: using a specific protocol to calculate the torques of the brackets, different for each patient. MFS most important objective is stability. For that, we calculate the torques to obtain:

  • Lower incisors stability: equilibrium position in relation to the musculature.
  • Upper incisors stability: parallelism between the upper central incisors axis and facial growth axis.
  • Canines overjet: to protect TMJ functionalism.
  • Premolars inner intercuspidation: for a better function.
  • Molars inclination: to establish a posterior pee curve.

6 – NEW AESTHETIC AND SELF-LIGATING BRACKET: that could be passive or active, using the MFS customized brackets prescription.

7 – MFS MECHANICS: using Nickel-Titanium wires during all the orthodontic treatment, the most time with upper Spee curve and lower antiSpee curve. We used also a new concept of anterior anchorage with anterior retainers.


  • To control oral dysfunctions as aetiological factors that can promote the relapse.
  • To help to the mechanics in the treatment of open bites and deep bites.
  • To maintain the lower arch in centric relation during the treatment.
  • To protect orthodontic treatment from bruxism.


  • Integration of functionalism with fixed mechanics.
  • Preventing relapse, searching stability at the end of the treatment.
  • Customizing brackets prescription and mechanics for each patient, using anterior and posterior anchorage methods.



  • Introduction: function and form
  • Key point: relapse in orthodontics
  • Negative oral stimuli an aetiological factor of teeth malpositions and malocclusions
  • Positive oral stimuli controlling oral functions
  • Oral Functions codification, objective diagnosis of functions
  • Stimulotherapy MFS devices: description and clinical use
  • Clinical cases treatment evaluated with videos: oral dysfunctions normalization
  • Functional appliances used in mixed dentition
  • Functional appliances used with fixed mechanics (brackets)
  • MFS Diagnosis: occlusogram and protocol for the calculation of the torque of an individualized prescription of the brackets: stability at the end of the treatment
  • Upper incisors axis and parallelism with the facial growth axis
  • MFS mechanics: treatment of different malocclusion
  • Clinical cases using self-ligating brackets; new aesthetic self-ligating interactive bracket
