Abstract
Purpose: The systemic effects of sleep apnea syndrome （SAS） are becoming a social issue as well as a medical and dental prob-
lem. This is a social issue as well as a medical and dental problem, and therefore, it should be taken into consideration in interdis-
ciplinary approach. This presentation will discuss cases of occlusal reconstruction from the prosthodontist’s point of view, taking
into consideration not only esthetics and function, but also airway. I will also introduce the Morphological Tooth Augmentation
Procedure （MTAP）, a new concept that is a variant of the recently popular vertical abutment tooth preparation （BOPT）, and a
less invasive prosthetic design based on the concept of MI.
Conclusion: Before prosthetic treatment after maxillofacial orthognathic surgery for patients with SAS, it is important to avoid
obstruction of the airway by the shape of the prosthetic device. The restorative treatment was performed using MTAP
（Morphological Tooth Augmentation Procedure）, a less invasive concept based on the concept of MI, and good results were
obtained. The systemic effects of sleep apnea syndrome （SAS） are becoming a social problem as well as a medical and dental
problem. This is an issue that needs to be taken into consideration in interdisciplinary approaches. In this presentation, I would
like to explain a case of occlusal reconstruction from the prosthodontist’s point of view, considering not only esthetics and func-
tion but also airway.
