Advancing Craniofacial Alignment and Posture


Head and neck alignment play a crucial role in overall health, yet traditional chiropractic or dental approaches often address these issues independently. In a groundbreaking study, Dr. G. Dave Singh, Dr. Chris Chapman, and Dr. Myles Preble explore the combined effects of atlas orthogonal (AO) chiropractic adjustments and biomimetic oral appliance therapy (BOAT) in their paper, Craniofacial Changes after Combined Atlas-Orthogonal and Biomimetic Oral Appliance Therapy.


Dr. Singh has stayed on the cutting edge of innovation in biomimetic oral appliances, pushing the field of dentistry and orthodontics to new heights. Dr. Chapman is a pioneer in the upper cervical world, bridging the gap of clinical care between airway orthodontics and upper cervical chiropractic care. As one o our  esteemed colleagues, Dr. Chapman carries the prestigious title of Diplomate of Chiropractic Craniocervical Junction Procedures, one of only approximately 80 worldwide. Through his efforts and ongoing collaboration between these worlds, we have seen substantial advancements in cranio-cervical and craniofacial stability, leading to significant improvements in clinical outcomes.



This study builds on the collective expertise of these three thought leaders, offering a multidisciplinary solution that significantly improves craniofacial alignment and provides a new perspective on addressing structural and neurological health.


How the Study Was Conducted


Eleven adults (average age 39.5) with atlas subluxations and malocclusions were evaluated. Participants first underwent AO adjustments, targeting upper cervical misalignment. Following these adjustments, they were fitted with a biomimetic oral appliance (DNA appliance®), designed to optimize craniofacial and dental structure. Radiographic assessments measured alignment changes at three stages: pre-treatment (T0), post-AO adjustment (T1), and after oral appliance therapy (T2). This systematic approach allowed researchers to evaluate the isolated and combined effects of each therapy on craniofacial alignment.


Key Findings and Implications


The study revealed that combining AO adjustments with BOAT created a powerful synergy for improving craniofacial alignment. Participants experienced a mean improvement of 68.2% in craniofacial alignment after the combined therapy. Specific parameters such as atlas cephalic displacement, cervical spine angles, and axis rotation showed significant enhancements. For example:


  • Atlas cephalic displacement decreased from 2.50 mm at baseline to 1.10 mm after AO adjustments and further to 0.50 mm after BOAT.
  • Axis (C2) rotation improved from 6.60° at baseline to 2.80° after AO adjustments and to 1.50° with the combined therapy.
  • Cervical spine-atlas angular rotation improved from 3.10° at baseline to 1.60° after AO adjustments and further to 0.60° after BOAT.


These structural improvements suggest the combination of AO adjustments and BOAT provides greater benefits than either therapy alone. Beyond alignment, the combined therapy addresses underlying compensation mechanisms that may enhance overall postural stability, airway function, and neurological outcomes. This evidence emphasizes the importance of integrating care when treating complex conditions like craniofacial and upper cervical misalignment.


A New Perspective on Structural Health


This study reinforces the idea that structural and neurological health is best addressed through a multidisciplinary approach. Combining AO adjustments with BOAT not only optimized craniofacial alignment but also highlighted how different healthcare specialties can work together to address root causes of structural imbalances.


At Cerebral Chiropractic Center, our primary goal is to uncover the root cause or causes of a patient’s problem and tailor a solution to their unique needs. This may involve precise upper cervical care alone or collaborating with other healthcare providers, such as airway orthodontists, for a comprehensive treatment plan. The more we explore multidisciplinary care for complex conditions, the more we find opportunities to achieve long-term structural stability and improved neurological outcomes—outcomes that might not be possible with isolated approaches. This research exemplifies how integrating expertise can lead to transformative results for patients.

Headache and Migraine Breakthrough

By Dr. Chris Slininger, DC, DCCJP • June 25, 2024
Pain, Throbbing, Aching, Pressure, and Tension In The Head There has been a breakthrough in understanding why headaches and migraines occur and how to fix them. More studies have shown that problems in the upper neck play a big role in causing headaches. A specialized method of correcting the upper neck can reduce or eliminate the symptoms without drugs or injections. Headaches are not normal even though they are common. The amount of times a person gets a headache does not make it normal. It actually just means the problem is more severe and there is usually a root cause to the problem that has not been uncovered yet. Most people do not know the root cause of their headaches. This leaves many people simply managing symptoms with medication or just coping with the pain. Currently, the most common treatment for headaches is prescription drugs, and treatment like Botox injections is on the rise, even though it only provides temporary relief. In recent years, there has been a greater understanding of one of the more common root causes of headaches and migraines. Headache and migraine pain often originate from nerves in your upper neck. More specifically, it is in an area called the brainstem. (See figure 1) This brainstem is the transition point between the brain and the spinal cord. It is located at the base of your skull into the upper part of the neck. Inside of this brainstem is a group of nerves called the trigeminal nucleus, which is the pain center for the head, face, and neck. If this trigeminal nucleus of the brainstem gets irritated, it causes the head, and sometimes the face, to hurt. One of the most common causes of this type of nerve interference is an upper neck misalignment. An upper neck misalignment occurs when the bones of the upper neck get out of place from a fall, concussion , car accident, or some sort of head or neck injury. Unfortunately, not many doctors, chiropractors, or neurologists are trained to evaluate this specific problem, leaving many people suffering from headaches for years. The key to addressing these types of headaches and migraines is to find the root of the problem instead of masking the symptoms. If a person is found to have upper neck nerve irritation from a misalignment, then they would be a candidate for our specialized type of care used to realign the upper neck with a gentle correction. Once the upper neck has been properly realigned, the bones no longer irritate the nerves and the headaches begin to subside. This specialized type of care is called Upper Cervical Care . With so many people suffering from headaches, there is good news. This specialized treatment is available the Cerebral Chiropractic Center in St. Petersburg, FL, which opens February 2024. Dr. Chris Slininger, the founder of Cerebral Chiropractic Center, is a craniocervical specialist who has been practicing in the Tampa Bay Area for the last 10 years. Upper Cervical Care is a powerful, precise, and gentle approach to long term relief. If you are serious about recovery, schedule a free consultation. You will meet with Dr. Slininger to learn more about headaches and migraines and to see if you could be a candidate for treatment.
