“…The objective of the present study was to evaluate volumetric measurements of the upper airspace of patients with OSA following wearing two different designs of MAA. MAAs used in this study were fabricated by CAD/CAM technology as it was strongly recommended by various studies due to its accuracy and adaptability (29)(30)(31).…”

INTRODUCTION: Obstructive sleep apnea (OSA) is a condition in which there is repetitive and intermittent occlusion of the upper airway (UA) during sleep. OSA can be treated through; continuous positive airway pressure (CPAP), surgery, or oral appliances. Mandibular Advancement Appliance (MAA) is considered a valid alternative, which can be the first choice in simple snorers and mild-moderate OSA. MAA can be either custom-made or non-custom-made, one-piece or two-piece, titratable or non-titratable. While Monoblock designs permit no mouth opening, two-piece appliances vary in permissible lateral jaw movement and in the coupling mechanisms which attach the two plates together. OBJECTIVES: measuring the change in UA volume after the use of two different designs of MAA (Monoblock and Biblock) MATERIALS AND METHODS: Twenty patients with diagnosed OSA were divided randomly into two equal groups: Monoblock group ; received Monoblock MAA fabricated using CAD/CAM technique at different advancement levels; 50% then 75% of maximum advancement, Biblock group; received Biblock MAA fabricated using CAD/CAM technique at different advancement levels; 50% then 75% of maximum advancement. UA volume of all patients were evaluated after three months of acclimatization of each stage of advancement through Cone-Beam Computed Tomography (CBCT). RESULTS: Biblock group showed statistically significant increase in UA volume at 75% mandibular advancement level, compared to Monoblock group (p=.001). There was statistically significant increase in UA volume percentage change from baseline to 50% advancement (p=.016), and also from baseline to 75% advancement (p=.001) in favor to Biblock MAA. CONCLUSIONS: Both Monoblock and Biblock MAA produced statistically significant increase in UA volume of OSA patients. Biblock MAA with elastics presented statistically significant favorable increase in UA volume in relation to Monoblock MAA.

Purpose CAD/CAM complete dentures have increased in popularity and a wide variety of systems are currently available. These prostheses present many advantages for clinicians, technicians and patients. Subtractive manufacturing is used by most of the available systems while a few manufacturers use an additive manufacturing technique. This article describes the currently available systems and materials available for the fabrication of CAD/CAM complete dentures and reviews the literature relative to their physical properties. Methods A comprehensive review of the literature was completed to enumerate the currently available techniques to fabricate CAD/CAM complete dentures and discuss their physical properties. A search of English language peer‐reviewed literature was undertaken using MEDLINE and PubMed on research articles published between 2000 and 2019. A hand search of relevant dental journals was also completed. Results The literature indicates the physical properties of CAD/CAM milled poly(methylmethacrylate) or PMMA as it is commonly described is superior to conventionally processed PMMA for the fabrication of complete dentures. Conclusion The incorporation of CAD/CAM technology into complete denture design and fabrication streamlines the clinical and laboratory processes and provides improved physical properties that enhance denture quality.

“…Tasaka et al demonstrated that experimental dentures fabricated using additive manufacturing techniques were also more accurate and obtained greater retentive forces than experimental denture bases fabricated using heat curing techniques. Recent papers 18 comparing milled and printed dentures show that both technologies produce dentures that are better fitting than those produced using traditional analog techniques 17 …”

The use of computer aided design and computer aided manufacturing in the fabrication of complete removable dentures has demonstrated that the prostheses produced are superior in many ways to removable dentures produced using analog techniques. A variety of clinical workflows that take advantage of digital technology have been shown to shorten the number of appointments required to produce high quality prostheses. This paper presents an overview of additive manufacturing in contemporary removable complete denture workflows and describes effective three appointment clinical techniques using additive manufacturing to produce a clinical trial denture and definitive prosthesis.
