ObjectiveThis study uses polysomnography and the Epworth sleepiness scale to assess the efficiency of the Ocluch©MAD in patients with Obstructive sleep apnea-hypopnea syndrome (OSAS), on overall respiratory disturbance indices (RDI), supine respiratory disturbance index (SRDI), minimum oxygen saturation, microarousals, CT90 (or ID90), sleep efficacy and snoring. These data are associated with skeletal class and facial biotype in order to establish predictive parameters for its effectiveness according to craniofacial morphology.Methods22 adult patients (between 38 and 60 years of age) of both sexes (7 women, 15 men) diagnosed with OSAS in the Hospital de Carabineros de Chile (HOSCAR) Neurology Unit were recruited and given the Ocluch© MAD in the hospital’s dental clinic, for its use during a three-month period. Patients were assess at the beginning and in the end of this period.Results87.5% of patients with mild OSAS achieved the success criterion and normalization; 71.5% of patients with moderate OSAS achieved the success criterion and 33.3% achieved normalization; 85.7% of patients with severe OSAS achieved the success criterion and 57.1% achieved normalization. All class I and mesofacial patients achieved normalization, but class II patients had the greatest proportional improvement.ConclusionsThe Ocluch MAD is an efficient low-cost alternative that should be considered among the therapeutic arsenal for a multidisciplinary approach to treating this disease.
RESUMENTanto en la práctica clínica como en la academia, siempre está presente la interrogante de cuál es la mejor posición mandibular para organizar una oclusión terapéutica y satisfacer los requerimientos estéticos y funcionales de los pacientes. Esta pregunta se podría responder desde la perspectiva de las diferentes escuelas de oclusión, siguiendo sus técnicas y utilizando su aparatología. Sin embargo, debido a que no existe suficiente evidencia científica que sustente la superioridad de una escuela sobre la otra, es preciso hacer una revisión donde se expongan los principios en que se basan las distintas filosofías oclusales, los autores que les dieron origen, la época en que surgieron y la terminología que usaron -desde el siglo pasado hasta nuestros días-, contrastándolas con la literatura científica actual. Esta no es una tarea fácil, ya que los estudios disponibles acerca de oclusión presentan gran variabilidad en la definición operacional de los términos, haciendo difícil su comparación. Se sugiere para el futuro buscar una estandarización de las definiciones y técnicas de registro, con el objeto de generar evidencia científica confiable, conducente a la creación de protocolos de recomendación para la toma de decisiones clínicas predecibles desde el punto de vista oclusal.

ABSTRACTBoth in clinical practice and academia, there is always the question about what is the best mandibular position to organize a therapeutic occlusion that satisfies functional and aesthetic requirements from patients. This question could be answered from the point of view of different occlusion schools of thought, following their techniques and using their apparatuses. However, due to the lack of scientific evidence to support the pre-eminence of a particular school over the rest, it is necessary to go through the princip les that provide the foundations for the different occlusal philosophies: the authors who gave birth to each school of thought, the time in which they were formed and the terminology they used, from the early 20 th century to present times and making a comparison with current scientific literature. This is not an easy task, given that available studies about occlusion feature a great variability in the operational definition of terms, making comparison difficult. The article suggests that it would be necessary for the future to look for a standardization of recording definitions and techniques. The aim is to generate reliable scientific evidence for the creation of protocols of recommendation for predictable decision-making from an occlusal point of view. Rev. Clin. Periodoncia Implantol.
