In this post we will describe the appliance that can be used to unravel cranial distortions and collapse: the ALF.


ALF is an acronym for Advanced Lightwire Functional Appliances.  In this post we will describe the use and purpose of the ALF device based on the work of  Dr. Gerald H. Smith.

Our Protocol for the treatment of Cervical Dystonia is based on the use of an upper ALF and a lower Gelb-Rectifier

ALF treatment is one of the main parts of of the Protocol for the Treatment of Cervical Dystonia that we have developed, alongiside  the Splint Therapy with a modified Gelb-Rectifier lower dental appliance.


Video Introduction to ALF Orthodontics/Orthopedics

The following video will provide an introduction to ALF in 2 minutes.


ALF History

The ALF appliance was originally designed in 1983 by Dr. Darick Nordstrom to be a vehicle in a comprehensive dental orthopedic/orthodontic treatment approach. What Dr. Nordstrom initially discovered and later a handful of his disciples is that the ALF proved to be the best instrument to unravel the structural distortions of the skull bones and stabilize the cranial/dental complex.

cranial derangement

ALF treatment is designed to correct cranial assymetries and derangement

The ALF System represents the missing link between conventional orthodontics and the more progressive functional orthopedic/orthodontic concepts. In reality, the ALF concept goes beyond the dental realm and supplies many answers to solving the age old problems of chronic somatic pain and generalized ill health.

The ALF appliance allows to:

  • Correct cranial bone distortions
  • Correct maxillary cant
  • Align teeth to stabilize the cranium

This is how an ALF device looks like when positioned on the maxillary teeth.

ALF in place

An ALF device placed on the maxillary arch. Note the Omega Loops that activate orthopedic forces.

ALF is little more than a wire anchored on first molars and upper canines. It is activated and creates orthopedic forces by expanding the omega loops. In essence, it takes advantage of the force of the tongue when swolloing to expand and align the maxillary arch, palate and teeth. The force that it uses is extremely limited and light but constant.

The fact that the ALF is not anchored to teeth (unlike traditional brackets for orthodontics) allows for the maximization of cranial movement.

The final goal of ALF treatment is to achieve balance of the dental planes:

  • Vertical
  • Transverse
  • Sagittal

The key to making the ALF appliance work is to adjust the appliance so that it balances four cranial indicators. Only by correcting crania bone alignment will the patient experience a cure.


Aligning the Cranial Base

When used properly, the ALF appliance enables orthodontists to correct cranial base abnormalities, which in turn corrects bodily function.

cranial base

The maxillae represents the anterior 2/3 of the cranial base

Since the maxillae represents the anterior 2/3 cranial base and functions as the balancing mechanism for the entire skull, foramen magnum and atlas, it must be corrected first. By aligning the maxillae, it provides the foundation or template to build into.

From a clinical perspective, if the maxillae is distorted so goes the rest of the body. Since 46% of the motor and sensory neurons of the cerebral cortex of the brain relate to the face and mouth, maxillary distortions have the potential of disrupting the central nervous system and changing neurological function throughout the entire body.

The body functions best when its structures are aligned at right angles


Balance of the maxillae is critical for maintaining total structural integrity of the entire craniosacral mechanism. The dental complex via the occlusion provides the self-correcting mechanism for balancing the skull bones.

When the maxillae is crooked and teeth alignment is faulty the entire body goes into a compensation mode. This fact is exemplified by patient feedback that their structural manipulations do not hold. Invariably a dental component exists when there is strutural instability. No amount of symptomatic treatment will correct the underlying dental problem. It is for this reason that patient problems linger.


Adjusting the ALF

The following video will provide a description of how to carry out adjustments of the ALF appliance to correct cranial derangement.


Case Study

The following case study drives home the importance of employing ALF Principles in orthodontic treatment.

case study alf

Case Study:  27-years-old school teacher. The chief complaints were: severe facial pain. Had to applied hot compresses on face to ease the pain before bedtime, difficulty talking, neck and shoulder pain, TMJ pain, headaches, unable to sleep through the night because of pain, fatigue

All symptoms started after conventional orthodontics were completed at age 17. Fifty doctors were seen during the 10 year period.


ALF appliance in place

The ALF appliance is designed to correct the maxillary horizontal plane as well as help realign the teeth. The foundation must be corrected first before the lower teeth are moved.


Pre-Tx model exhibits canted maxillary transverse plane. The cranial base was distorted and the mandible over closed on the left setting up compression of the left TM joint and a structural domino effect.


The patient’s 10 years of pain were resolved when the distorted planes were corrected

RX Evidence

The following picture is a case treated by Dr. Jeffrey Brown. It shows the pre and post treatment RX of a young man who could not attend college, had severe arm spasms/tics, could not see straight, and experienced dizziness.


As the film shows, following 1 year of ALF treatment, the nasal septum is straighter, the palate more even, the cervical spine is better aligned, his eyes are more even, the mastoid bones (by the ears) are more level, the neck straighter, the zygomatic arches more level and he can open the mouth more. He is back in school too.

  2. So reading the splint therapy, I understand it all minus the cross splint. How do I know if that is what I need to do in the beginning. I’m also confused about how to register the bite.
    Thank you!


      • Ok, thank you for your time. I just am clueless if I need a cross splint. I guess I can play around. I really hope this technic helps me with my symptoms. I feel so many of the symptoms in my mouth, ear and eye on the right side. Feels like my right side collapsed. And my maxilla on the right side has changed, making my teeth hit incorrectly.


      • Playing around is not thr correct word. You may want to experiment until you find the splint that makes you feel better. Be very conservative until you master the techniques to register a bite on polimorph. Start with normal bite splints. In the end it id not difficult. Registering a bite on a splint directly in your mouth is not rocket science. It takes a little time to learn.. but in one hour you can master it.
        It takes 2 miutes from start to end to register a bite on a splint with polimorph.

      • Ok, experiment I will. I get my splint on Tuesday. How much polymorph do you put on each side? I watched the YouTube video on your blog showing the technique the girl used, but couldn’t tell how high to build up the polymorph.
