14) The Role of the Rectifier in the Profile View (sagittal plane, vertical axis): The Lever Effect

A “Eureka!” moment

In one of the earlier chapters I alluded to the lever effect. At that time I was able to intuit the effect that the Rectifier, placed on my lower teeth, had on my body. I really had the feeling of a lever that pushed my skull upwards and finally stretched my back.

I was able to perceive through my body the verification of the following principle: in the moment of occlusal contact, to the degree that the jaw pulled backwards, pushing itself towards the cervical area, that much more was the skull driven upwards, extending the spine.

But for a long time I was not able to explain rationally how this process took place.

The principle reason that kept me from understanding how a lever found a practical application in the craniocervical mandibular system was due to my erroneous conviction that the fulcrum was positioned on the atlanto-occipital joint.

At first glance it seemed evident to me that the skull did not have its fulcrum on the teeth, but on the atlanto-occipital joint. Truly, it is known that the skull really does tilt on the atlanto-occipital joint. It was here that the fulcrum had to be. Except that it wasn’t. On the other hand, that theory had never satisfied me completely. In fact, there was no scientific proof for it, because it doesn’t explain the reason for the change in the inclination of the skull.

Thus, the skull did not have its fulcrum on the atlanto-occipital joint. The sole role of the atlanto-occipital joint is to permit the skull to tilt. There is another force that pushes the skull upward. It was there that the fulcrum must be. More precisely, that fulcrum is placed between the teeth (the point at which the muscular force is applied) and the atlanto-occipital joint (the point at which the skull is driven upward).

At that time I had not yet identified the point on which the skull rotated, that is, the fulcrum!

One day, during my research I came across some pictures. Two of them were illuminating!

The first were those of a T-Scan which showed the pressure applied to the maxillary arches during occlusion that led me to understand that the fulcrum resided, as it should, in the area of maximum pressure. Thus I had finally identified the fulcrum, it was on the teeth!

Once the fulcrum was identified, the other insight was gained by superimposing two images: one was a famous one of Archimedes, who would lift the Earth by means of a lever on a point of support, and the other was that of a skull.

I simply put the skull in place of the Earth. In fact, in the original picture there was a man with a lever who was lifting the Earth. Moreover, I made the molars on the fulcrum match up so they corresponded with the rock the lever, meant to lift the Earth, stood on. In fact, in picture 33 the lever rests on the molars, to lift the skull.

It was easy to position the skull on the lever just there where the Earth sat, as I had finally found the fulcrum. The fulcrum that lifts the skull had therefore to be the missing dental height recreated by the Rectifier, right there in the premolar and molar area.

Finally everything came back to me. Finally I had found the scientific explanation for how the Rectifier worked. This tool lifted the skull in regard to the jaw only in the premolar and molar area, making it alter its inclination in regard to its point of support (the jaw).

The skull finds a fixed point of support precisely on the jaw. We will explain this phenomenon in the following pages.

The important thing is that finally there was clarity!


The lever effect

“Give me a place to stand on, and I will move the Earth.” (Archimedes)

A very curious anecdote: a kind of irony that the first cervical vertebra, that one that supports the skull, is also called “the atlas”.

Atlas was a picture in Greek mythology. He was a Titan, son of Zeus and Clymene. According to Hesiod, Zeus forced him to carry the entire sky on his shoulders. The punishment was inflicted on him for having been allied with Zeus’s father, Cronos, who lead the revolt against the Olympians. In the Odyssey he is described poetically as one of the pillars of Heaven.

Archimedes recognized very well the efficacy of the lever, to the point of being able to summarize its extraordinary potential in the famous quote: “Give me a place to stand on, and I will move the Earth.”

The function of the Rectifier, used according to the Starecta method, consists in recreating that “place to stand on” to then apply a fulcrum to raise the skull.

Here is how the lever works:

The head is the heaviest part of the human body, weighing on average 4 kg, for which nature has devised a very ingenious method to keep it in place at the highest point in our body without weighing us down.


To reduce the load on the neck muscles, nature makes use of a lever.

The lever that supports the skull is made up of the jaw and the teeth. If the teeth have adequate vertical height, with uniform distribution of force along all the arches, the lever functions well, otherwise it is necessary to create artificial height.

Thanks to the Rectifier, the necessary height is created. In this way the principle of action and reaction can be applied (Newton’s Third Law of Motion), described earlier.

The Rectifier intervenes on the dental arches to create a new occlusion. The new occlusion, by means of this method, causes:

1) the skull to reposition itself along the vertical skeletal axis

2) a redistribution of the forces of pressure found within the teeth.

These forces can be measured with the T-Scan 3.

Once the Rectifier has had an effect, the forces of pressure redistribute themselves along the dental arches and, consequently, the fulcrum positions itself uniformly in the premolar and molar area.

In this case, based on Newton’s Law of Action and Reaction, a force applied to an object from one direction generates an equal force that works in the opposite direction.

The masseter and temporal muscles are responsible for closing the teeth, thus for occlusal contact. It is precisely during occlusal contact that the lever effect is generated, which permits the lifting of the skull. Such a lever is defined as a “first class lever”.

The first class lever: with this type of lever the fulcrum is placed between two opposing forces; this lever can be advantageous, disadvantageous, or neutral. As we can see in picture 37, the fulcrum is located between F1 and F2.


The advantage or disadvantage of the lever is based on the change of position of the fulcrum. By means of inserting the Rectifier, a new occlusion is created. Thanks to this new occlusion, the pressures exerted by the contact of the teeth are shifted to the premolar and molar area.

As we can see in picture 39, the lever effect works in such a way that the skull rotates upward as if it were being pulled by the atlanto-occipital joint.

In pictures 40 and 41 we see the Rectifier which repositions the fulcrum in the premolar and molar area.
