DAS TTA SYSTEM NACH FAVERO: EINE INNOVATIVE IMPLANTATGESTUTZTE THERAPIE DER KLASSE II." Innovative Class II implant-supported therapy: the Favero TTA (total treatment appliance) system
No full textThe possibility of using the Pendulum in a modular version, with removable arms, springs, arches and other components, makes it a first-choice appliance in the lingual aesthetic treatment of most class II malocclusions. The Pendulum, due to its design characteristics, is an intra-oral fixed and purely lingual device. As a result of this, it has achieved a position of superiority in lingual technique therapy. The use of the Pendulum appliance in its standard form, or with some technical modifications to make it more versatile, has extended its therapeutic use to the field of lingual orthodontics. As in interceptive treatment, it can be seen how the Pendulum successfully achieves its established aim regarding correct molar relationship, while also solving crowding of the incisors thanks to the front area of anchorage (F Pendulum). In adult treatment the F Pendulum is just as valid and appreciated. However, particular care should be taken regarding the biomechanics of distalization in order to avoid the undesirable effects of extrusions and tipping. On the other hand, distalization tends to be mostly bodily. In adult treatment the insertion of superstructures in the acrylic part has made it possible to introduce various techniques such as implant anchorage, distalization of mid-anterior modular areas and alignment and contraction of the incisors. The multi-bracket lingual technique can be used in on-going treatment immediately after molar distalization or in later advanced phases of treatment, where the functions of the Pendulum are extended

In Parabolas Salomonis. In Ecclesiasten. In Canticum canticorum : Tre esposizioni iberiche
No full textA partire dall’età carolingia nelle biblioteche prima della Francia, poi dell’area alpina e dell’Italia, si diffonde un trittico di commenti anonimi ai libri biblici che la tradizione attribuisce a Salomone: Proverbi, Ecclesiaste, Cantico dei Cantici. Queste esposizioni, chiaramente riconducibili a un’origine iberica, circolano in più redazioni, frutto di interventi di adattamento e ampliamento operati in più momenti e luoghi. In questo volume si ricostruisce per la prima volta l’articolata tradizione – spesso congiunta ma non solo – di questi commenti e si pubblica l’edizione critica (la princeps per i primi due) delle loro diverse redazioni, restituendo la comune identità a quelli che dai cataloghi e repertori apparivano testi isolati, oscurati dall’anonimato o da false attribuzioni. La storia dell’esegesi dei tre libri biblici può così arricchirsi di un tassello non trascurabile, come mostrano la dimensione e l’estensione geografica della tradizione manoscritta che ci ha tramandato questa costellazione di commenti
Le tour du monde: les mémoires de voyage d'un émigrant de Schio en Russie et au Canada au début du XXme siècle
No full textThe essay exploits the published memoirs of an Italian emigrant in order to inquiry on the modalities of the reconstruction of past experiences concerning emigration and the assessment of family relationships. The role of the correspondence and of written and printed supports in the reconstruction performed in the memoirs is evident, and is connected with other experiences affecting the reconstruction itself, from movies to novels
Control of tooth movements with the Speed system
No full textSteps taken to evolve the straight-wire system eventually led to the development of self-ligating brackets. The Speed system, comprehensive of bracket, wires, force, and anchorage management, is a significant evolutionary development. The design property of the fourth wall in the Speed bracket allows the Ni-Ti wire to be placed in the slot fully. Closure of the gate activates the wire for the desired type and direction of tooth movement. A sequence of round, square, rectangular wires, Ni-Ti and stainless steel, permits a complete control of the tooth position during the different phases of the orthodontic treatment. In this study, the effectiveness of the system is investigated in four groups of patients: Class II, div 1 with four first bicuspid extractions; Class II, div 2 non-extraction; Class II div 1 non-extraction in mixed dentition; Skeletal Class III skeletal treated with an orthodontic-surgical treatment plan. Treatment results were assessed using the intra-oral photographs, and radiographs taken at the start of treatment, at the end of active treatment, and in retention. Satisfactory control of tooth positions during the horizontal, mesio-distal and torque movements, both in the extraction and non-extraction cases were observed. During the course of treatment, in extraction cases where sliding mechanics are used, shifting of the anchorage from posterior to the anterior unit is possible as a result of increased forces. This shift is facilitated by the activation of the spring clip on the anterior teeth. The advantages of the self-ligating Speed system are the low levels of force used, low friction, and precise control of tooth movement

Virtual study models: a comparison of modular application systems.
No full textAbstract
INTRODUCTION:
Virtual study models made their first appearance on the orthodontic market in 1999. The early systems offered two-dimensional images; reliable 3D images of study models were obtained only with the introduction of laser technology. Virtual study models have reduced the number of limitations and obstacles associated with the use of conventional plaster models and resulted in the creation of the "paperless orthodontic office". To understand their drawbacks, advantages and affordability, the different systems available for virtual dental casts were compared.
DISCUSSION:
The systems envisaging the use of 3D virtual study models are: Orthocad, e-models, Orthoproof, SureSmile, Invisalign and Libra. All of these systems offer model "manipulation" options, whereas only Orthocad, e-models and SureSmile offer advanced levels of software complexity, so as to ensure: virtual set-up, computer-aided bracket placement, planning and construction of orthodontic appliances. The use of hand-held scanners calls for highly specific skills. Basic requirements to use digital models include: a personal computer, internet access, management software.
CONCLUSION:
The digital elaboration of orthodontic study models is developing beyond the collection of morphologic and diagnostic data, towards the planning and production of orthodontic devices, through the use of morphing simulating the several phases of the treatment. Digital 3D models can be used at a basic and at a more advanced level, depending on the clinician's level of experience.

Respiratory disorders in paediatric age: orthodontic diagnosis and treatment in dysmetabolic obese children and allergic slim children
No full textObesity and allergic susceptibility are worsening problems in the most industrialised countries. With different mechanisms, they both lead to a deterioration of children's life quality because they affect the respiratory system, leading to asthma and respiratory disorders such as mouth breathing and obstructive sleep apnoea. The latter are related to specific types of malocclusions that require an early diagnosis and specific multidisciplinary treatment. The purpose of this work is to show the characteristic signs and symptoms of these disorders in children of the two phenotypes (allergic and slim, obese and dysmetabolic). Intercepting such issues allows both pediatricians and paediatric dentists to refer the child to a multidisciplinary team of specialists able to deal, in a holistic way, with both the physical and behavioural causes, and also with the consequences on systemic and craniofacial development in particular
