Research

A curated reading list.

The peer-reviewed papers Dr. Deal returns to most often — and the same papers we teach from at Real Deal Seminars. A few are flagged as parent-readable for those who want the source material themselves.

  • 2005 · Clinician

    Maxillomandibular expansion for the treatment of sleep-disordered breathing in children

    Guilleminault, C., Stoohs, R., et al. · Sleep Medicine

    Establishes a direct mechanism: arch expansion enlarges the airway. A foundational paper for the airway-aware paradigm.

  • 1968 · Clinician

    The primary role of functional matrices in facial growth

    Moss, M.L., Salentijn, L. · American Journal of Orthodontics

    The biological case for plasticity. Function shapes form throughout development, not only in childhood.

  • 1981 · Clinician

    Primate experiments on oral respiration

    Harvold, E., et al. · American Journal of Orthodontics

    Classic primate study showing that forced mouth breathing alters facial growth — a direct mechanistic precedent for the human pattern.

  • 2010 · Both rooms

    The naso-maxillary complex, the mandible, and sleep-disordered breathing

    Kim, J., Guilleminault, C. · Sleep & Breathing

    Connects narrow naso-maxillary anatomy to sleep-disordered breathing severity in adults and children.

  • 2008 · Clinician

    Airway protection: the missing link between obstructive sleep apnea and TMD

    Simmons, J.H., Prehn, R.S. · Sleep

    Proposes that protective postural responses to airway compromise drive a meaningful share of TMD cases.

  • 2012 · Parent

    Sleep-disordered breathing in a population-based cohort: behavioral outcomes at 4 and 7 years

    Bonuck, K., et al. · Pediatrics

    Large cohort showing behavioral consequences of pediatric sleep-disordered breathing — useful when speaking to parents.

The literature is the framework. The cohort is the protocol.

Reading the papers gets you the paradigm. Real Deal Seminars gets you the case sequencing, the appliance choices, and a year of cases you can apply on Monday.
