Background: Although they have proven effective in the resolution of mild to moderate malocclusions, aligners demonstrate substantial limitations. More complex malocclusions therefore require a combination of auxiliaries, or a hybrid approach involving both aligners and fixed appliances, such as miniscrew-supported appliances or sectionals. This case report presents a 25-year-old female patient with a severe transversal discrepancy associated with an anterior open-bite tendency effectively treated with a tooth bone-borne palatal expander characterized by two expansion screws (tandem expander) and a hybrid treatment with aligners.

Aim: The aim of this article is to compare the performance of ZeroExpander® realised using PEEK or PA12 for the expansion of the maxilla in paediatric patients, exploring a new concept for approaching maxillary expansion with a metal-free fixed automatic appliance, based on pre-programmed set-up and anchored on deciduous teeth.

Materials: It is a retrospective comparative study with a sample of 40 children in early or mixed deciduous dentition and transversal maxillary deficit, 20 treated with ZeroExpander® in PEEK and 20 treated with ZeroExpander® in PA12 with a mean age of 7.3 years old.

This case report describes a complex full-step class II case in a young adult patient treated with lingual straight-wire appliance and upper first molar extraction. As the patient refused a surgical treatment, she was offered the best possible camouflage with the double aim of obtaining an ideal occlusal relationship and maintaining the profile; appropriate biomechanical strategies, including extraction choice and anchorage control during space closure, were needed to achieve the planned results. This case report demonstrates the possibility of successfully resolving severe sagittal discrepancies in an adult patient without surgical treatment by means of a completely invisible non-compliance technique, with the extraction of the most compromised teeth.

Effects of Thermoforming on the Mechanical, Optical, Chemical, and Morphological Properties of PET-G: In Vitro Study.

Polymers (Basel)

January 2024

School of Dentistry, Dean: Prof. Massimo Cordaro, Catholic University of the Sacred Heart, IRCCS "A. Gemelli" University Polyclinic Foundation, Largo Agostino Gemelli 8, 00168 Rome, Italy.

The effectiveness of clear aligners in correcting malocclusions is closely linked to the properties of the materials used to make them. The polymers used in the manufacture of clear aligners have well-established properties. However, the process of manufacturing clear aligners, known as thermoforming, involves thermal and mechanical shocks that may alter these properties.

Background: The aim of the study was to compare the accuracy and reproducibility of three different 3D facial scanning systems, relying, respectively, on stereophotogrammetry, structured light and a smartphone app and camera.

Methods: Thirty subjects have been scanned with three different facial scanning systems, stereophotogrammetry, structured light and a smartphone app and camera. Linear measurements were compared with direct anthropometries measured on the patient's face, while the study of areas (forehead, tip of the nose, chin, right and left cheek) was evaluated by overlapping scans using the Geomagic Control X program.

Objective: The aim of the preliminary pilot single-center retrospective cross-sectional study was to analyze and compare the presence of non-secretory salivary inflammatory biomarkers in pediatric patients with West syndrome, Noonan syndrome, and a healthy control group.

Patients And Methods: A total of 60 saliva samples were collected during dental check-ups. The saliva samples collected were analyzed by liquid chromatography.

This article describes a class II subdivision malocclusion successfully treated by an invisible lingual appliance. The combination of en-masse distalization by interradicular palatal mini-screws and inner unilateral class II auxiliaries, first by intermaxillary elastic, later by a class II coil spring, resulted in a dento-alveolar correction, allowing one to maintain the appliance completely invisible. At the same time, the inclination of buccal sectors was normalized by a correct torque expression with set-up overcorrections, resulting in a significant improvement of the buccal corridors.

First and second branchial arch involvement in mandibulofacial dysostosis Guion-Almeida type.

Eur J Paediatr Dent

December 2023

Department of Life, Health and Environmental Sciences, Postgraduate School of Orthodontics, University of L'Aquila, Italy.

Mandibulofacial dysostosis Guion-Almeida Type (MFDGA; OMIM#610536) is a rare autosomal dominant genetic disorder caused by heterozygous pathogenic variants in the EFTUD2 gene. Mandibulofacial dysostoses are characterised by the core triad malar hypoplasia, maxillary hypoplasia and dysplastic ears, all derived by the impaired development of the first and second branchial arches. Differential diagnosis is often challenging.

Background: The aim of this paper is to remind how evidence-based paediatric dentistry should not only consider the best available scientific evidence relating to the patient's oral conditions but it should also consider the patient's needs beyond the clinic. In a child-family-oriented approach, the best restorative treatment for a primary tooth could not be the proper one for the child as a whole. Preservation of dental tissues as much as possible, without involving the pulp, is called minimal intervention dentistry (MID) and it is closely related to "selective caries removal" and "bioactive restorative materials".

The aim of this paper is to perform an observational descriptive study of the Obstructive Sleep Apnea Syndrome (OSAS) in a population of children by evaluating the prevalence and role of sex and age variables. The 22-item Pediatric Sleep Questionnaire (PSQ) was administered to parents of children aged 3 to 12 years. The questionnaire is a very simple tool since it allows for the indication of patients with possible OSAS diagnosis through a cut-off of 0.

Article Synopsis
  • The study aimed to compare the effects of two types of orthodontic treatments for mild class III malocclusion in children, specifically bimaxillary removable plates with class III elastics and elastodontic devices.
  • Twenty children, aged between 6.5 to 9.5 years, were treated and analyzed for changes in occlusion and maxillary morphology before and after treatment.
  • Results showed that both treatments corrected malocclusions, but elastodontic devices led to greater changes in the shape of the palate, suggesting they may be more effective in improving overall jaw alignment.

Aarskog-scott syndrome (AAS): a case report.

Eur J Paediatr Dent

September 2023

Department of Life, Health-Environmental Sciences, Postgraduate School of Orthodontics, University of L'Aquila, L'Aquila, Italy.

Background: Aarskog-Scott syndrome (AAS) is a rare developmental disorder characterised by facial dysmorphism, genital and limb anomalies as well as disproportionate acromelic short stature. Clinical diagnosis is based on physical examination and the presence of the most characteristic clinical signs. The diagnosis can be finally confirmed by molecular tests, which identify mutations in the FGD1 gene.
