Different approaches for digital workflows have already been presented for their use in palatal plates for newborns and infants. However, there is no evidence on the accuracy of CAD/CAM manufactured orthodontic appliances for this kind of application. This study evaluates trueness and precision provided by different CAM technologies and materials for these appliances. Samples of a standard palatal stimulation plate were manufactured using stereolithography (SLA), direct light processing (DLP) and subtractive manufacturing (SM). The effect of material (for SM) and layer thickness (for DLP) were also investigated. Specimens were digitized with a laboratory scanner (D2000, 3Shape) and analyzed with a 3D inspection software (Geomagic Control X, 3D systems). For quantitative analysis, differences between 3D datasets were measured using root mean square (RMS) error values for trueness and precision. For qualitative analysis, color maps were generated to detect locations of deviations within each sample. SM showed higher trueness and precision than AM technologies. Reducing layer thickness in DLP did not significantly increase accuracy, but prolonged manufacturing time. All materials and technologies met the clinically acceptable range and are appropriate for their use. DLP with 100 µm layer thickness showed the highest efficiency, obtaining high trueness and precision within the lowest manufacturing time.

This case report presents surgically assisted orthodontic treatment for an adult patient due to labial exostosis, prominent malar, and unesthetic chin. Her treatment was total arch distalization with modified C-palatal plate for maxillary arch and miniscrews for mandibular arch. In addition, she was treated with alveoloplasty, malarplasty, and genioplasty to improve the consistency of her profile. The total treatment duration was 28 months.

Congenital decubital ulcers were found in 94% of newborn infants with unilateral cleft lip and palate in the course of a systematic study of a large cohort study (N = 52). The procedures for diagnosis, documentation, and follow-up are described. The ulceration area at birth varied over a wide range. The ulcerations were usually located in the posterior part of the vomer. Sonographic evidence supports the hypothesis that the ulcerations are caused mechanically by the motor activity of the tongue during the fetal and newborn period. The decubital ulcer disappeared in each case within 5 days following the implementation of a palatal plate.

ABSTRACT Objectives To compare the dental and skeletal treatment effects after total arch distalization using modified C-palatal plates (MCPPs) on adolescent patients with hypo- and hyperdivergent Class II malocclusion. Materials and Methods The study group included 40 patients with Class II malocclusion (18 boys and 22 girls, mean age = 12.2 ± 1.4 years) treated with MCPPs. Fixed orthodontic treatment started with the distalizing process in both groups. Participants were divided into hypo- or hyperdivergent groups based on their pretreatment Frankfort mandibular plane angle (FMA) ≤22° or ≥28°, respectively. Pre- and posttreatment lateral cephalograms were digitized, and 23 variables were measured and compared for both groups using paired and independent t-tests. Results The hyper- and hypodivergent groups showed 2.7 mm and 4.3 mm of first molar crown distalizing movement, respectively (P < .001). The hypodivergent group had a slight 2.2° crown distal tipping of first molars compared with 0.3° in the hyperdivergent group. After distalization, the FMA increased 3.1° and 0.3°, in the hypodivergent and hyperdivergent groups, respectively (P < .001). SNA decreased in the hypodivergent group, while other skeletal variables presented no statistically significant differences in the changes between the groups. Conclusions The hypodivergent group showed more distal and tipping movement of the maxillary first molar and increased FMA than the hyperdivergent group. Therefore, clinicians must consider vertical facial types when distalizing molars using MCPPs in Class II nonextraction treatment.

Infants with craniofacial malformations (CFMs) are at increased risk of various clinical problems, including respiratory and feeding disorders, the result of which may be long-lasting. An improvement in clinical care can be achieved by prenatal diagnosis and interdisciplinary birth preparation. Feeding problems may particularly be stressful for the family and require a team approach involving nursing staff, speech therapists and nutritional specialists to anticipate, avoid and treat sequelae such as failure to thrive or recurrent aspirations. Special techniques (eg, optimisation of breast feeding, alternative feeding methods or manual orofacial therapy) may be used individually to improve feeding competence; supplemental nutrition via a nasogastric or gastrostomy tube may be temporarily necessary to ensure adequate weight gain. The high prevalence of respiratory disorders in infants with craniofacial abnormalities requires anticipation and screening to prevent growth failure and neurological deficits. Treatment of upper airway obstruction varies widely, strategies can be divided into non-surgical and surgical, and in those aimed at widening the pharyngeal space (eg, prone position, palatal plates, craniofacial surgery) and those bridging the narrow upper airway (eg, nasopharyngeal airway, modified palatal plate, pneumatic airway stenting, tracheostomy). The complex management of an infant with CFM should be performed by a multidisciplinary team to offer specialised support and care for affected families.
