Please be advised that this blog is a “work in progress” that is only a few weeks old and manifestly and evidently needs constant improvement to achieve the accuracy, validity and scientific standards that we wish to maintain.

We are using this blog to report on the progress of the research and experimental treatment that we are carrying out, as we develop it in real time and within the limits of time and resources that bind us.

Your commentaries, peer review, corrections and even financial support are very wellcome.

To further understand our reasearch, approach and method, please read:

Principles of Splint Therapy
A description of the principles on which we base our protocol for the treatment of Cervical Dystonia and other occlusion realated movement disorders with varying degrees of neurological symptoms (from Tourette’s, to postural collapse, Parkinson’s and Generalized Dystonia).

Protocol for the Treatment of Cervical Dystonia
A step by step description of the 3 phases of the DIY protocol that we have developed for the treatment of Cervical Dystonia.

The Molar Lever
Our analysis of the bio-machinics of the Molar Lever and how dental occlusion is related to posture and skeletal allignment.

Phases of Lateral Postural Colapse
Our analysis of the descending skeletal and postural effects of a collapsing and twisting skull that does not find adequate support in the dental arches.

The Rectifier
A description of the adaptive intra-oral aplliance -dental splint – that we use to treat Cervical Dystonia and the orthopedic forces that it produces by progressively pushing the mandible in retrusion, maxila in extrusion and elevating the skull by stretching and aligning the cervical vertebrae.

Bibliography and links to scientific research on the treatment of Dystonia and other neurological movement disorders with a bio-mechanical approach.

Postural Colapse and Dental Arches
A set of animations that present grafically the type of skeletal and postural effects that we intend to produce over a few months by modifying occlusion and the direction of forces between the skull and the mandible.

Beginning of Treatment
Postural analisys, MR evidence and description of the situation of our patient at the beginning of this experimental treatment.

First Rectifier: Cross-Bite Splint with Lateral Moral Lever Effect
Description of the dental splint that we are using for the first two weeks of treatment and the logic behind the selection of the direction and nature of the orthopedic forces that it produces.

Iatrogenic Damage: When the Dentist is a Butcher
Our review of how modern dental theories on occlusion oversimplify and misunderstand the biomechanics of the stomatognatic system, leading to a high potential of traumatic dental treatments.

What is Dystonia?
A short description of the symptoms and clinical definition of Dystonia for those who are not familiar with this desease.

    • Thank you for your replay. No. Atbthe moment there is nobody working at it in the USA. But next summer I will be in the USS for a few weeks and something might come up. If you are suffering from Cervical Dystonia and wish to try this method, please be advised that you can do it easily. All you need is to register as a patient and we will send you all the information and give you assistance online. We actually wellcome patients willing to try it and participate in our research. You will need to find a dental lab that makes your base splint (roughly aeound 32$), buy some self curinf resin (anorher 30-40$) and then tou can start making your own rectifiers at your own home. Starecta provides all the information and videos on how to build the rectifiers and register your bite every 2 weeks.

  4. Hello Marcello, I am a dentist in USA. I’m keen on helping with this project and would like to know how to. I’m currently treating patients with ALF and splint therapy with quite a bit of success. I do not focus only on cervical dystonia. I use these appliances primary for correction of posture and breathing disorders and thus help straighten the teeth. I would love to know and do more. Please send me an email. We are a team of one Osteopath and dentist along with a nearby Chiropractor.
    Thank you

  5. Marcello. Your site is a fantastic sourse of information. I have many of the symtoms that you have described. The right hand side of my head is pulled down towards my right shoulder and is slightly twisted to the left. I think this started about 2 years ago after I had been to a dentist to repair 2 broken upper right hand side molars. I have ordered the retainer and the polymorph. My question is do I need to add extra height to the right hand side or do just register the bite as you have describe in this blog.


    • Tjank you.
      If you register the bite as described in the posts (that is phonetic A or O and regular or crossbite splint), the extra height will be put on the splint authomatically.
      Remember that this is a treatment lasting months or years with regular new registrations of the bite. At the beginning you may even need daily new registrations as all crabial bones and TMJs start to move.


  6. Thanks Marcello. Will do as you suggest. I am also seeing a great dentist that is slowly adding height to my back teeth and will fix my bite. However, you suggest that this should be done only after my symptoms have dissapeard (after a month or so of using the splint). Do you think I should stop this treatment untill the symptoms have gone. Ive got to be honest that after the first session my neck seems worse.


    • Absolutly. Stop working directly on your teeth. I did the same mistake for two years before I realized what I needed to do.
      You will see that by registering a bite in the splint with polymorph your neck will fell better and your spine get aligned UNTIL you need to do another splint. Stretching and untwisting your spine and aligning your cranial bones is a process that takes months or years. At every step your occlusion will change massively.
      Start working with the splint and you will realize why asjusting your teeth does not work. It is like adjusting a door that does not close because the frame is twisted by working on the door.
      Read my post on principles of splint therapy.


  7. Thanks alot for your quick responce. One last question. I am also seeing a chiropractor who knows about TMJ stuff. But she never seems able really do anything that permantly fixes anything. I am thinking of using a cranio sacral therapist instead. What do you think.


    • No pop, crack, manipulation of your vertebrae can be stable and hold if your occlusion, TMJ and cranial alignement are off.
      If you do not treat and repair the leverd that are pushing your skeleton out of alignment, it is useless.
      You are actually harming yourself by doing that.
      When you are in dental splint and ALF therapy, craniosacral maipulations help mobilize the cranial bones and vertebrae. And speed up the process.


  8. Thanks Marcello. Another question, definately the last. I am missing 3 upper teeth. The first molar and second premolar on the left hand side. The first molar on the right hand side. I have a denture to replace missing teeth. Its a long story. Should I make the splint with the denture or without the denture. Should I just used trial and error. Will the splint still work.


    • It is unfortunate. The ALF will not work even closely as well if you do not have upper first molars.
      Butnthe Gelb Rectifier will work.
      You will probably not be able to get as good results as I did because tou can not unlock the suture innthe palate between dirst molars and aexon premolars.
      Do the Gelb Rectifier WITH the denture on. You need a molar lever effect to stretch the spine. That can be done.
      And you will get great relief.
      You can treat and align all the problems below the neck. But above the neck it will be very difficult.

  9. Thanks Marcello. As long as my neck is straight and I can move it from side to side I will be very happy. I am not expecting miracles. I intend to see a cranio sacral therapist as well, so that should help.


  10. Hi Marcello, would it be possible to arrange a consultation over the phone? I had a question about what to do about an asymmetrical mandible (with one ramus longer than the other). Is there an email address I can reach you at?
    Thank you,
