The Rectifier


The foundamental instrument of this experimental method to treat, reverse and possibly cure Secondary Idiopatic Cervical Dystonia is based on the Rectifier, an intra-oral appliance (dental splint) that is the result of the research and development carried out by Moreno Conte.

Moreno’s developed this technology out of genius and desperation: the twisting colapse of his skeletal structure had brought him to face death. He had to find a way to survive, and he did.

The intra-oral aplliance, that Moreno Conte designed and tested on himself and hundreds of patients around the world, produces orthopedic forces that are engineered to move and modify the skeletal structure in order to recover vertical balance, symmetry and allignment of all the structures that support the skull.


Rx Evidence

In the following pictures, you can see how 7 months of use of the Rectifier can change the bone structure supporting the dental arches, maxila, mandible, skull and cervical vertabrae.


This patient suffered from cronic neck and back pain, difficulty in phonetic expression, broken voice, Cronic Fatigue Syndrome and neurological problems including difficulty to focus and concentrate. 7 months of treatment resolved all the symptoms. Before resorting to the Starecta method, this patient had tried many sorts of treatment, traditional and alternative medicine, with no improvement in his condition.

The pictures on the left were taken before the treatment. Pictures on the right were taken 7 months later. All the described symptoms had disappeared.


And here below, you can appreciate a model of how the skeletal structure and allignment was modified.

How does it work?

The Rectifier is a progressively adaptive, dynamic lower dental splint that needs to be adjusted every 2 weeks and produces orthopedic forces.

This dental splint takes advantage of the swallowing reflex to activate a lever centered on the molar teeth to produce orthopedic forces that move the mandible in retrusion, the maxila in extrusion and elevate the skull.


It needs to be used 24 hours a day, most importantly during meals and at night.

Progressively adaptive

Adjustments of the splint are carried out every 2 weeks directly in the mouth, using a self-curing resin that becomes solid in 2-5 minutes.

The patient is instructed to sit on a chair and try to extend his spine and neck as far as he can, while he keeps is mouth open. This position is the result of trying to separate vertically the tip of the head from the pelvic bone as much as the patient possibly can.

In this position, a new bite is registered onto the splint, letting the resin become solid as the patient sits still. The result is that the new extended skeletal position is cristalized in a new relation between the dental arches, a new functional position between the mandible and the skull.

Orthopedic forces

This dental splint takes advantage of the swallowing reflex to activate a lever centered on the molar teeth to produce orthopedic forces that move the mandible in retrusion, the maxila in extrusion and elevate the skull.

The following picture explains the principle.


This tool lifts the skull in regrad to the jaw only in the premolar and molar area, making it alter its inclination in regrad to its point of support (the jaw). It effectively moves the fulcrum of the lever distally (towards the back side of the mouth) and uses the weight of the skull and the movement of the mandible when swallowing to produce a force that lifts the skull, extends and alligns the cervical spine.

In the next two pictures tou can se how the Molar Lever works:


By applying force with the hand along the same direction that the masticatory muscles do (red arrows in the picture), you can clearly appreciate how the posterior part of the mouth is subject to a stretching force (green arrows in the picture): the white plastic sustainers slide along the rails and the distance between the mandible and the maxilla in the back side of the mouth is raised about half a cm.


That is how the lever centered along the molar part of the dental arches stretches the back of the cervical spine and lifts the skull.

The Rectifier to Treat Dystonia

The method and technology that Starecta has developped have a scientifically proven and documented record of removing the morphological alterations of a twisted spine, those curvatures that go by the names of scoliosis, hyperlordosis and hyperkyphosis.


It takes advantage of several laws of Newtonian mechanics applied to the human body, understood as a musculoskeletal, biomechanical system, in order to bring the body back to a correct posture. By means of a lever, the Rectifier can allow the spine to stretch itself in a totally natural way.

Condylar Shaped Teeth

The Rectifier reproduces in the mouth what is technically defined a “Gerber bilaterally balanced occlusion with condylar shaped teeth.”

The following picture show how it works.

The Rectifier creates in the lower molars the shapes and curves of the glenoyd fossa and in the upper molars the shape and curves of the head of the condyles.

Thus, the movement of the mandible is articulated through the xurves of the molar teeth to mimic the movements of the condyles in the glenoyd fossa. The next picture explains how the Rectifier allows for a Bennet Movement that alligns the axis of the plain of occlusion with the axis of the cervical spine.

It is worth boting that this concept is the exact opposite of the paradigm of the currently prevalent concepts of occlusion based on anterior guidance. With the Rectifier, molar teeth of the opposing dental arches work as a joint articulating movement that describes curves, with forces between antagonistic teeth in many different directions. In the “mutually protected with anterior guidance” prevalent occlusion philosophy, teeth only have vertical forces in their contacts.

This Blog

In this blog, we will report on how we test the theory that Secondary Idiopatic Cervical Dystonia is strictly related to a skeletal and postural colapse that comes to affect, compress and strain the brain stem, driven by a sinking skull that does not find appropriate support in the dental arches.

We are applying the Rectifier to treat a case of Secondary Idiopatic Cervical Dystonia.

      • You have to ask your local nearest dentalnlab to make one. and then you have to buy polymorph onlkne from Amazon.
        Obviously, thrb dental lab will say that they can only sell splints to dentists. It is justba form of corporativism disguised as regulation. The lab will charge 30$ to build it. The dentist will charge 300$ to process the order.

        Find ways to work with thw lab directly. We all do. Some say they are dentists, same use dentist friends, some become friends of the lab ownwr, some hure a dental lab student for a specific work. I do research with the lab and a dentist and that gives me access to orsering all kinda of dental appliances directly. This is a DIY method.


  5. My daughter,13 yrs of age has been diagnosed with idiopathic scoliosis & an underbite(Mandibular prognathism).Surgery was recommended for both these.We are trying alternative methods at the moment-back brace,physiotherapy & schroth method of exercise for her back which appear to be working.We don’t have to make a decision on orthognathic surgery until she is 16.Therefore my daughter would be interested in trying the Rectifier if it could help in any way & is open to taking part in a research program.We live on West coast of Ireland,Cather


    • Hi Catherine. Please send me an email at and I will five you the contact info.
      Personally, I think thatntou ahouldw try everything possible before tou even consider orthognatic surgery. It is obscenely traumatic, prone to all kinds of complications (lip paralysis due to nerve damage happens in a great number od cases) and based on a model of dental occlusion which I consider wrong (only vertical forces) that has no scientific base.
      Please read the post on this blog dedicated to “Can tou trust your dentist?” for a detailed explanation on why I do not believe in orthognatic surgery.
      It was porposed to me. I did a little research and I have bit been able to find a single person who did this kind of surgery who would do it again or would recommend it.


  6. I also have a question. Is this something that you wear indefinitely? It seems like if you were to stop after your posture is corrected that your posture would revert. Is this something that is worn 24/7?


    • Hi Saima. I do not sell anything. The best option for you is to join the Starecta community on Facebook.

      They will provide you with videos and info on how to make dental splints at home ( ).

      In the community you will ve able to find more info on how to start splint theraphy and support and advise from people who are currently doing the treatment.

      For example, please watch this video to learn how to build a splint at home.


  7. Pingback: Principles of Splint Therapy | Bio-Mechanical Dystonia

    • Scot: read the post on “principles of splint therapy” on this blog, buy the polimorph online and start. Home made. Don’t yourself. And join the Starecta Facebook group for support and advise.
      All the information in the post I mentioned. It is the last in the blog . section.


      • I am very interested in this technique however I don’t understand why there is not a clear price on the website. No information as to how to use it. It is fishy then. I went to the Facebook page but it is designed so you received information passively and don’t reply. If there is a discussion group on Facebook, I would like to know but have not seen. If what they are described is true, I could really benefit from the rectifier.


      • Ina, there is no information about price because I do not sell anything. I am just describing what I am doing.
        This is a DIY (do it yourself) method. It is necessary to study and understand what is happening to your body. And it is necessary to learn how to build your own splints. And to find a local dental lab that will build your own base splints on which you will register and re-register new bites..
        In the Starecta group on Facebook you can find the comments of other patients who are doing the same thing. It is a great help. Just like the info on my blog. It is a great help.
        You will have to join the group to be able to exchange comments with them.


  8. Hi I don’t see that much extra advice about how to get this treatment on the facebook page. Could you please tell me any further information on this, I have mild scoliosis.

    Thanks a lot for all your info.


  19. What price?? You buy the materials yourself and you don’t buy the materials from Starecta. You should provide more info when you comment. What price are you talking about?


    • I had a local dental lab manufacture the base splints and ALF.
      The prices:
      – Base splint 30€
      – ALF 70€
      Then I bought polimirph online through Amazon and it cost me 9€.

      That means that I spent a grand total of 140€ for the appliances that I needed to carry out the DIY protocol on myself.


  20. Hey Marcello interesting article and very convincing. However, I just find this a little too good to be true, as this mouth piece seems to cure multiple issues. Though plausible , I want to as you how the results have been for you. I want to know if this alleviated with spinal and facial asymmetry for you before I attempt to commit.



    • Anthony: this is a treatment. It does not cure. And it is a treatment that addresses cranial collapse with an ALF, postural collapse with and Gelb rectifier dental splint; TMD with specific kind of dental splint registration; neurological symptoms with a specific rehab.
      The blog has plenty of pictures and info of how it has worked for me.


  21. Hi Marcello,

    I had my right molar tooth extracted by my dentist because I broke it in pieces and there was no solution to fix it. So, my dentist suggested me to put a dental implant there. What should i do in this case to not impact on the Rectifier proper usage?


    • I would have to see to have an opinion. In general: of it is a mandbiular molar there is no problem whatsoever. If it is an upper maxillary molar, you should probably get an ALF to prevent the skull from collpsing onto.itself and cranial.bines to get deranged.


      • Hello Marcelo,

        Thank’s for the fast response!

        I forgot to mention which the side that I think that I need to use the lever to correct my low jaw and sinking skull is the left side ( the side where the lever should be build), though I also guess which the case that I mentioned above is something which also need to be considered in the treatment.
        Is there any possibility you could evaluate my picture?




  22. Hi Marcelo,

    I have another question. In the two pictures above showing how the molar lever works, I saw that one side of the Rectifier is higher than the other. Is the higher Rectifier side appllied on the side where the pacient has the lower jaw and sank skull? I mean, my intention is to restore all my left side muscles which are weak and sore from the neck to the foot, rotating my spine and pelvis due to left molars maloclusion. Is that correct what I wrote above according to the Rectifier protocol?

  24. Hello Marcelo,

    I ddin’t find any dentist or neurlogist that is open to learn about bio-mechanic treatments (using the info on this blog) to work with him. So I would like to ask you to keep answering my questions as soon as you can.

    After start using the rectifier and take a better look at my face, I found that my left zigomatic bone is lower than on the right side. I think I am in the rigth direction when I put more polimorph on the left side of the splint to stop my skull to sink futher, right?


    • I would suggest you to keep looking for a dentist to work with. The height of the splint on either side is determined by the phonetic registration thst you do. It is a natural slow process. Do not add polimirph on one side looking for a quick instant fix.


  25. Hello Marcelo,

    Thank’s for your valuable information.

    I would like your opinion about my situation. I had the both rigth third molars teeth extracted in 2008 and after two years I started to have some neck pain which later, went to my whole left back and leg. I asked a dental prothestic to make a splint based on the same splint that you show in your website and now I’m pain free. I received a copy of my dental cast from the dental prothestic and after doing a thoroughly examination, I find out that my left superior third molar is touching my left inferior third molar and because of that my first and second left superior and inferior molars are not touching each other ( no oclusion). Do you think if I extract my left superior and inferior third molars, my left side oclusion will improve? I also have my left inferior arch lower than the right inferior arch. Do you think that after my left superior and inferior third molars extraction, my teeth on the left inferior arch will move backwards allowing better teeth distribution and oclusion?

  26. Hello Marcelo,

    Thanks for the kick answer! I ‘ve tried to join the facebook group, but the I 1ve got this message below:

    Sorry, this content isn’t available right now

  27. Hello Marcelo,

    Although after I ‘ve read and watched the content about the ALF available here, have finally understood the process, I still would like to ask you a question about my left third molars. My lower left third molar is higher on the external side than on the internal side and it is not alowing my leff third molar to have a proper occlusion, futhermore it is affecting my left first and second molars superior and anterior to have a proper oclusion. Do you think that I can use a brace on my left lower third molar to align itself and improve my third left molars occlusion as they are having occlusion in the wrong way and not allowing my first and second left molars to have occlusion. What is your sugestion?




  28. Hello Marcelo,

    Can I post a photo of my open mouth on the Facebook Biochemical Dystonia group for your evaluation?

  34. Hello Marcello Mazza,

    Can the Rectifier be a substitute of the alf to correct all the facial assymetry that the alf resolves?

    I have almost the same facial assymetry that you had.


    • The Rectifier works to correct scoliosis below the skull: TMJs, mandible, upper cervical and all the way down the spine.

      Cranial scoliosis above the neck can only be treated with the ALF and cranial ostheopathy.

      You need both an ALF and a Rectifier to treat cranial, TMJ and spinal derangement.
