Introduction: Three adult case reports (79 and 60 years old females and a 60 year old male) were selected to demonstrate maxillary morphogenesis. These patients were treated for maxillary underdevelopment which can affect occlusion and airway space due to the relationship between the tongue and the hard palate.
Intervention: Each patient wore the Homeoblock™ appliance for a minimum of twelve months. The Homeoblock™ consists of ‘Adams clasps’ on the bicuspids with a baseplate that incorporates a palatal expansion jack screw. The appliance is relieved from the palatal tissues. Flap springs rest on the anterior teeth and a Hawley arch wire extends from left to right canine. A bite block is placed on the second bicuspid and first molar on the less developed side.
Results: Improved tongue position, tone, and the resulting increased pharyngeal airway size were found with each patient.
Discussion: Once nurture seemed clearly distinct from nature. External influences seem to be able to influence a network of chemical switches within our cells collectively known as the epigenome.
Conclusion: These three cases demonstrated how modifications of tissues in the craniofacial region can occur with adult patients in their 6th and 7th decade of life.
