  • Design and fabrication of a Sleep Apnea Device using computer-aided design/additive manufacture technologies
    Proceedings of the Institution of Mechanical Engineers Part H: Journal of Engineering in Medicine, 2013
    Co-Authors: Noor Al Mortadi, Jeffrey Lewis, Dominic Eggbeer, Robert J Williams
    Abstract:

    The aim of this study was to analyze the latest innovations in additive manufacture techniques and uniquely apply them to dentistry, to build a Sleep Apnea Device requiring rotating hinges. Laser scanning was used to capture the three-dimensional topography of an upper and lower dental cast. The data sets were imported into an appropriate computer-aided design software environment, which was used to design a Sleep Apnea Device. This design was then exported as a stereolithography file and transferred for three-dimensional printing by an additive manufacture machine. The results not only revealed that the novel computer-based technique presented provides new design opportunities but also highlighted limitations that must be addressed before the techniques can become clinically viable.

  • an individually adjustable oral appliance vs continuous positive airway pressure in mild to moderate obstructive Sleep Apnea syndrome
    Chest, 2002
    Co-Authors: Winfried Randerath, Markus Heise, Rolf Hinz, Karlheinz Ruehle
    Abstract:

    Background: For the treatment of nonsevere obstructive Sleep Apnea syndrome (OSAS), mandibular advancement Devices (MADs) are employed as an alternative to nasal continuous positive airway pressure (CPAP) therapy. However, very few specific data on the effectiveness of MADs in this group of patients are available. We therefore compared an individually adjustable intraoral Sleep Apnea Device (ISAD) that permits movements of the lower jaw in three dimensions, with CPAP in the treatment of patients with an Apnea/hypopnea index (AHI) < 30/h. Methods: In a randomized crossover study, 16 men and 4 women (mean SD age, 56.5 10.2 years; body mass index, 31.2 6.4; AHI, 17.5 7.7/h) were treated for 6 weeks with each modality. Results: In the initial phase, a significant improvement in AHI (baseline, 17.5 7.7/h; ISAD, 10.5 7.5/h [p < 0.05]; CPAP, 3.5 2.9/h [p < 0.01]) and in breathing-related arousals (baseline, 8.9 6.1/h; ISAD, 3.7 3.3/h [p < 0.01]; CPAP, 1.4 1.6/h [p < 0.01]) was achieved with both modalities. Considering all 20 subjects, after 6 weeks of treatment, normalization of the respiratory parameters was seen only with CPAP. However, 30% of the patients had a lasting reduction in AHI to < 10/h with the ISAD also. The patients considered the ISAD to be easier to use (scale of 1 to 6: ISAD, 1.8 1.1; CPAP, 3.1 1.5 [p < 0.05]), and indicated greater utilization of the Device in comparison with CPAP. Conclusion: Even in patients with mild-to-moderate OSAS, CPAP is the more effective long-term treatment modality. In the individual case, the better compliance seen with the ISAD may be advantageous.
