A novel method for fabricating nasoalveolar molding appliances for infants with cleft lip and palate using 3-dimensional workflow and clear aligners

Does Infant Orthopedics and Neonate Lip Surgery Influence the Occlusal Relationship in Patients With Unilateral Cleft Lip and Palate (UCLP)?

“…There is still a field of active research on the long-term effects on maxillary growth, and these can be confounded by the results of surgical techniques for lip and palate repair (Kapadia et al, 2020). Although Bous et al (2020) published a proposal for treatment with IO with the intention to reduce the time of consultation and visits, it is known that this protocol may not be applicable and reproducible in large centers, as part of public policies, since it requires closer care and more frequent consultations, the so-called burden of care (Ross, 1987; Sitzman et al, 2015).…”

“…Additionally, some rehabilitation protocols make use of orthodontics as preparation and complementation of primary plastic surgeries (Burston, 1958; Rosenstein, 1969; Hotz, 1969; Lapa, 1970; Huddart, 1974; Hotz and Gnoinski, 1979; Gnoinski, 1982; Jacobson and Rosenstein, 1984; Lopes, 1986; Bennun et al, 1999; Grayson et al, 1999; Grayson and Cutting, 2001; Prahl et al, 2001; Liou et al, 2004; Jaeger et al, 2007; Garfinkle et al, 2011; Papadopoulos et al, 2012; Jayashree and Paul, 2013; Van der Heijden et al, 2013; Rau et al, 2015; Hosseini et al, 2017; Bous et al, 2020; Gong et al, 2020; Kapadia et al, 2020).…”

“…Several types of appliance design are described in the literature. These appliances are classified as active, when force is applied to the maxillary segments aiming to move them in medial direction to reduce the cleft width (Rosenstein, 1969; Lapa, 1970; Bennun et al, 1999; Grayson et al, 1999; Grayson and Cutting, 2001; Prahl et al, 2001; Bous et al, 2020; Gong et al, 2020; Kapadia et al, 2020); and passive appliances (Hotz, 1969; Hotz and Gnoinski, 1979; Gnoinski, 1982; Jacobson and Rosenstein, 1984; Lopes, 1986; Jaeger et al, 2007; Fisher, 2007; Satoshi et al, 2020) which aim to provide conditions for the intrinsic developmental potential, inducing spontaneous approximation of the alveolar segments (Figure 1).…”

Digital Presurgical Infant Orthopedics in COVID-19 Crisis

“…Intraoral scanners can accurately capture the palatal cleft area and other anatomic details in 3D digital format (ie, STereoLithography [STL] file). These 3D digital models of cleft defect can be used to create a digitally designed sequential NAM appliance for 3D printing or sequential digital models for 3D printing upon which sequential NAM appliance may be constructed (Ahmed et al, 2019;Zheng et al, 2019;Batra et al, 2020;Bous et al, 2020;Gong et al, 2020;Schiebl et al, 2020;Shanbhag et al, 2020). Digital NAM appliances have a more precise fit and are as effective as traditional NAM devices (Branstetter and Patel, 2019;Bous et al, 2020;Gong et al, 2020).…”

Details of various recent techniques on dNAM fabrication and treatment (publications from the year 2019 and 2020) have been summarized in Table 1.…”
