Clear aligners effects on aesthetics: evaluation of facial wrinkles
Background: To evaluate the facial aesthetic effects of orthodontic treatment performed with clear aligners and
to compare it to an untreated control group, on lower third facial ageing in adult patients through the use of the
Wrinkle Severity Rating Scale (WSRS) at the beginning (T0) and at the end (T1) of the study period.
Material and Methods: A clear aligners treated group (TG) of 68 patients was compared to a control group of 33
untreated patients (UG). Each group was divided in 2 subgroups according to age: subgroup 1 if under 40 years
of age and subgroup 2 if over. Facial aesthetics of the lower third was evaluated at T0 and T1 by a panel of five
aesthetic experts with WSRS.
Results: Statistically significant changes were found in all subgroups comparing WSRS scores at T0 and T1. The
between group comparisons revealed that wearing clear aligners produces a statistically relevant improvement in
lower third facial aesthetics both in younger (p < 0.05) and older (p < 0.001) patients.
Conclusions: The present retrospective cohort study has successfully shown that malocclusion therapy conducted
through the use of clear aligners in a population of adults affected by dental crowding has beneficial effects on
lower third facial ageing
Contro i nemici della risata : Le stagioni teatrali di Umberto Simonetta al Teatro Gerolamo
Direttore del Teatro Gerolamo fra il 1978 e il 1983, Umberto Simonetta è stato autore, regista e produttore di numerose pièce di successo, fra le quali Sta per venire la rivoluzione e non ho niente da mettermi (con Livia Cerini), Mi voleva Strehler (con Maurizio Micheli), che ha oltre mille repliche all’attivo, Ne ho mangiata troppa (con il figlio adottivo Luca Sandri).Head of the Teatro Gerolamo between 1978 and 1983, Umberto Simonetta was the author, director and producer of numerous successful plays, among which The revolution is about to come and I have nothing to wear (with Livia Cerini), I wanted Strehler (with Maurizio Micheli), who has over a thousand repeats to his credit, I ate too much (with his adopted son Luca Sandri)
Correlation between transverse and sagittal dimensions in early stage: a retrospective study between patients treated with clear aligners and untreated patients
Abstract Background The interceptive treatment of Class II malocclusion using clear aligners is still debatable. This retrospective study analyzes the short-term occlusal and cephalometric effects in 40 growing patients with Class II malocclusion. Methods The sample was divided into 2 groups: Following the dentoalveolar expansion protocol, the first group was treated with clear aligners (GI). The second group was untreated (GN). Dental arches were scanned before and 1 year after the therapy. Similarly, linear measurements on digital casts and cephalometric ones on lateral X-rays were compared. Maxillary (Lmax), mandibular intermolar length (Lmand), and posterior transverse intermolar discrepancy (DIT) were evaluated. The distance between the mesiobuccal cusp of the upper first molar and the buccal groove of the first lower molar was considered at both sides (Cdx and Csx). The statistical descriptive analysis of T0 and T1 values was performed using a paired t-test, setting a p value < 0.05. Results A greater improvement in molar and skeletal Class II parameters in the GI group compared to the GN group was detected. Specifically, in GI, Lmax improved by 3.3 mm, Lmand by 1.1 mm, and DIT improved from − 2.1 mm to 0.1 mm, while Cdx and Csx decreased by 1.28 mm and 1.13 mm, respectively. In contrast, the GN group showed smaller improvements, with Lmax increasing by 1 mm, Lmand by 0.8 mm, DIT improving from − 2 mm to -1.8 mm, and both Cdx and Csx exhibiting slight increases of 0.04 mm and 0.09 mm, respectively. No statistically significant differences were observed regarding divergence or the correlation between skeletal and dental measurements. Conclusions Dentoalveolar expansion using Invisalign First appears effective and predictable with better outcomes than the control group. An improvement of skeletal Class II is detected in the treated group with dental improvements on maxillary arch

Analysis of the Changes in Occlusal Plane Inclination in a Class II Deep Bite “Teen” Patient Treated with Clear Aligners: A Case Report
Background: Optimal management of hypodivergent growing patients demands a strict control of vertical dimension and to exploit the growth potential. If a deep bite malocclusion causes a traumatic contact between the upper and lower incisors and affects the facial appearance, an early interceptive treatment is recommended. The aim of this case report is to outline the clinical management of the occlusal plane of a growing Class II division 1 deep bite patient treated with aligners and Class II elastics. Methods: The treatment lasted 11 months and was divided into two phases. Treatment goals included improvement of the soft tissue profile and basal bone relationships through an increase in the mandibular third of the face and a sagittal advancement of the mandible. The correction of the curve of Spee involved intrusion of the mandibular incisors and extrusion of the mandibular premolars. Results: The cephalometric analysis at the end of the treatment displayed significant differences in the skeletal and occlusal pattern along with aesthetic improvements. Conclusion: The final cephalogram showed a consistency between the planned tooth movement and the clinical results. Although definitive recommendations must be withheld until longer follow-up is available, the patient presented here shows that the treatment protocol yielded positive mandibular growth

La 'riforma' degli ammortizzatori sociali [The 'reform' of social protection for the unemployed]
The Author analyzes the reform of social protection provisions for the unemployed. The reform turns out to be rather a soft rationalization of the existing provisions. There are important provisions and an attempt at outlining a systematic framework. However, the pieces of the whole jigsaw puzzle are far from finding the right place. We assisted to a virtual reform, the main object of which is that of restoring the political credibility of the Country. However, on the whole, the Author does not believe that something much different could be have been done, considering the deep economic crises of the Country, the complexity of the provisions under review and the fact that the Monti’s Government is a temporary one. The main shortcomings of the reform, however, are the lack of a universal provision on minimum income for the unemployed and the softness of the link between unemployment benefits and labour market active policies

Protezione sociale ed istituti della riconciliazione
The Author explains the importance of finding a definition of reconciliation in the area of social protection in order to be able to have a critical approach to the different instruments of reconciliation. She looks then to the definition of reconciliation in the European Union legislation and stresses how the notion of reconciliation is linked to substantial equality and to the redistribution of roles within the family as well as to a bi-directional nature of its provisions and to the presence of a complex whole of rationes. These elements are then used to suggest a path for the definition of reconciliation in the social protection field
