Ciocca L, Fantini M, De Crescenzio F.
Nel caso in cui non si disponga di modelli preoperatori prima di iniziare la costruzione di una epitesi auricolare o nasale, è necessario avere modelli virtuali di riferimento che possano essere correttamente adattati sulla superficie del difetto. A tale scopo da un imnsieme di modelli reali in gesso presi da pazienti sani, si è proceduto alla costruzione di una biblioteca virtuale di modelli nasali ed auricolari che possano essere utilizzati anche nei casi congeniti di agenesia auris bilaterale, come accade ad es. come nella sindrome di Treacher Collins.
La realizzazione dei modelli digitali è avvenuta attraverso la scansione laser 3D dei modelli in gesso. Le differenti prese necessarie per la completa aqcuisizione di ogni calco sono state quindi registrate e fuse in un unico modello tridimensionale.
Vengono descritti nel dettaglio due casi di studio.
7.2 Progettazione di scaffold per la rigenerazione ossea: impostazione del modello di studio animale
Uno dei problemi più cogenti della Protesi Maxillo-Facciale è la morfologia ossea e mucogengivale residua dell’anatomia dei mascellari dopo l’intervento chirurgico maxillo-facciale. Molte variabili influiscono nel risultato post-operatorio a livello morfologico, fra cui principalmente la mancanza di una corretta progettazione protesica preventiva dell’intervento di exeresi maxillo-facciale. Infatti spesso il chirurgo si trova a dover affrontare il caso clinico da un punto di vista demolitivo e ricostruttivo, senza una base di progettazione protesica finale di come il caso dovrà successivamente essere riabilitato che serva da riferimento durante l’intervento. Tale problematica è alla base di un ampio protocollo di ricerca che gli autori conducono sulla possibilità di progettare scaffold in grado di ripristinare il corretto volume e di ospitare al loro interno cellule staminali che consentano la rigenerazione tissutale ossea.
Per tale obiettivo attualmente si sta lavorando su un modello di studio animale di cui si forniscono alcuni dettagli a titolo di esempio degli sviluppi futuri della ricerca nel campo della Protesi Maxillo-Facciale
TUTE PULITE PER UN LAVORO SPORCO. CULTURE DELLA CORPORATE SOCIAL SUSTAINABILITY NELLE FONDERIE ITALIANE
No full textLo scritto approfondisce i costrutti di cultura della c.d. Corporate Social Sustainability (“CSS”) e sostenibilità della vita organizzativa nelle fonderie italiane, inquadrate nella letteratura di settore come organizzazioni ad alto rischio. Le fonderie sono comunemente percepite come “Industrie 3D: Dirty, Dusty and Dangerous”, poco attente alla sostenibilità ambientale, sociale ed economica. La nostra ipotesi è che in questi contesti sia possibile identificare elementi culturali in grado di “rendere pulito” un lavoro “sporco”, così da migliorare la sostenibilità della vita lavorativa e contribuire alla transizione da “Industrie 3D” a “Industrie 3P: Profit, Planet and People”. Gli obiettivi conoscitivi riguardano (i) la descrizione degli elementi culturali in cui si esprime la CSS, e (ii) lo studio delle relazioni esistenti tra la CSS e altri oggetti teorici, (iii) la ricognizione di conoscenze empiriche a sostegno di processi di trasformazione di contesti lavorativi in un’ottica di sostenibilità organizzativa. A tale proposito abbiamo articolato un progetto di ricerca etnografico in tre fasi, giungendo ai risultati di cui in seguito.
In particolare, la prima fase si è sostanziata in numerose osservazioni etnografiche su un campione di sei fonderie per descrivere la CSS, mostrando la sua espressione in diversi elementi culturali (pratiche, norme, valori, credenze, rituali, ruoli) legati ai seguenti oggetti teorici: pianificazione, comunicazione, team, sicurezza, contesto/contenuto, riconoscimento, identificazione, giustizia, management e conoscenza. Nella seconda fase, attraverso quattro focus group, sono state verificate le conoscenze sviluppate precedentemente e introdotto l’oggetto “tecnologia”. La relazione dell’oggetto “tecnologia” con la CSS è stata approfondita nella terza fase, mediante le c.d. “Visual Methodologies” e concludendo che le nuove tecnologie sono fondamentali per lo sviluppo di culture della CSS poiché agevolano la gestione di spazi e movimentazioni, di contesto e contenuto lavorativo, sicurezza, riconoscimento e identificazione, conoscenze, organizzazione del lavoro, impegno e innovazione.This dissertation explores the constructs of Corporate Social Sustainability (“CSS”) culture and sustainability of organizational life in Italian foundries, considered as high- risk organizations in the industry literature. Foundries are commonly perceived as “3D Industries: Dirty, Dusty and Dangerous”, with little attention to environmental, social and
economic sustainability. We deem that in these contexts it is possible to identify cultural elements that can “make clean” a “dirty” job, so as to improve the quality of working life and contribute to the transition from “3D Industries” to “3P Industries: Profit, Planet and People”. The research goals concern (i) the description of cultural elements in which CSS is expressed, and (ii) the study of relations between CSS and other theoretical objects, and (iii) the recognition of empirical knowledge to support transformative processes of work contexts in an organizational sustainability perspective. We have developed a three- phase ethnographic research project, achieving the outcomes set out below.
The first phase focused on ethnographic observations in a sample of six foundries to describe CSS, showing its expression in several cultural elements (practices, norms, values, beliefs, rituals, roles) related to the following theoretical objects: planning, communication, team, safety, context/content, rewarding, identification, justice, management and knowledge. During the second phase, through four focus groups, the previously developed knowledge was assessed and the object “Technologies” was introduced. The relation of the latter with CSS was studied in the third phase, through the so-called “Visual Methodologies” and it was concluded that new technologies are fundamental to the development of CSS cultures as they facilitate the management of space and movement, work context and content, safety, recognition and identification, knowledge, work organization commitment and innovation
Indian Literature and the World. Multilingualism, Translation and the Public Sphere
No full textIndian Literature and the World is a collection of critical essays featuring up-to-date scholarship on the most vibrant yet under-studied aspects of Indian writing today. Multilingualism, current debates on postcolonial versus world literature, the impact of translation on an “Indian” literary canon, and Indian authors’ engagement with the public sphere all shape the orientation of our volume. The essays cover political activism and the North-East Tribal novel; the role of work in the contemporary Indian fictional imaginary; history as felt and reconceived by the acclaimed Hindi author Krishna Sobti; Bombay fictions; the Dalit autobiography in translation and its problematic international success; development, ecocriticism and activist literature; casteism and access to literacy in the South; gender and diaspora as dominant themes in writing from and about the subcontinent. Troubling Eurocentric genre distinctions and the split between citizen and subject, we wish to approach Indian literature from the perspective of its constant interactions between private and public narratives, thereby proposing a method of reading Indian texts that goes beyond their habitual postcolonial identifications as “national allegories”
Digital Options for the Rehabilitation of the Atrophic Edentulous Maxilla
No full textObjective:
The aim of this study was to describe fully digital workflows for the Prosthetically Guided Reconstructive Surgery (PGRS) of edentulous patients affected by atrophic maxilla.
Methods:
The preoperative provisional removable full-denture was used as starting point to determine aesthetics parameters, occlusion of the final prosthetic rehabilitation as well as the respective maxillary implant positions using conventional softwares for the diagnosis of available bone and for the design of the full-arch prosthesis. The regenerative option (bone augmentation using customized titanium mesh), or the long implant option (navigated zygomatic implants) were both digitally projected depending on the patient needs. After implants healing, two sets of digital impressions were acquired: set #1 was the digital impression of implant positions; set #2 was the digitalization of the provisional full denture together with the impression of the rear side. The two sets were digitally combined into a single file. The metal framework of the final prosthesis was designed and manufactured using digital hybrid manufacturing technology and clinically evaluated with Sheffield test and radiographs; at the same time a resin prototype was produced for clinical try-in of aesthetic and functional parameters.
Results:
Aesthetic parameters and the occlusion of the provisional removable full-denture were digitally transferred to the provisional and definitive full-arch fixed prosthesis. The digital models were 3D-printed in occlusion to finalize in three steps the full-arch prosthesis.
Conclusions:
The workflows of PGRS allowed realizing the full process of the prosthetic and surgical rehabilitation of edentulous patients with atrophic maxilla using a complete digital CAD-CAM technology.

“Plurality, Identity, Democracy, Globalization…. A conversation with Sunil Khilnani” in Indiascapes. Images and words from globalized India
No full textRossella Ciocca interviews Sunil Khilnani author of the much appraised The Idea of India: one of the best non-fictional introductions to the complexities of politics in contemporary India. The strengths and weaknesses of present-day uneven modernity are discussed around a few strategic topics. First of all plurality, which in its linguistic, cultural, religious, ethnic variety has been vindicated since Independence as a foundational value, is seen as the quintessential resource for achosen practice of syncretism but also in danger of becoming the very source of fragmentation and implosion in a country increasingly maimed by fundamentalism and fanaticism. Democracy is then interrogated between the comfortable perspective of the firmly established and normally operating mechanisms of democratic routine, on the one hand, and the flawsof a still dramatically unjust system of distribution of rights and opportunities, on the other. Identity politics is in turn analysed both in its positive action of mobilizing society around the problem of social upgrading and in its unwelcome side effects of increasing practices of rigid and restricted classification fomenting division and violent sectarianism. In the end Indian growing cultural appeal upon the globalized scene is questioned in its complex relationship with the country’s quest for a role of protagonist in political as well as economic affairs upon a new multilateral international stage

Prosthetically Guided Maxillofacial Rehabilitation Cad-CAM technology
No full textAs recently reported by a review of the literature from 1990 to 2011 (1), maxillofacial prosthesis are a reliable treatment option to restore maxillofacial defects and improve the quality of life of the patients who undergone cancer surgery. This book has born from the clinical experience during the last fifteen years, and it aims to describe the recent advances in using CAD-CAM technology for the construction of the extra-oral maxillofacial prostheses and of surgical guides and bone plates used in the maxillofacial bony reconstruction after cancer removal. The atlas form of the book allows readers to better understand and duplicate the procedure into their own clinical practice; the style of e-book allows the authors to update once a year the contents, giving to the reader the last findings in this research area.
The approach of the authors to the extra-oral prosthetic rehabilitation is related to the concept that a good plastic surgery may be better than a facial prosthesis, and for this reason a maxillofacial prosthesis represents the last option to offer to the patient whenever a surgical attempt should be a failure in terms of aesthetics and function.
Moreover, for the oral and maxillofacial reconstructive surgery the fibula free flap is still today the gold standard to restore wide defects, but from a prosthetic point of view a lot of rehabilitative problems are still present when a patient is scheduled for the final prosthetic rehabilitation after using the fibula free flap. Our clinical research has been intended to prevent this important problem, giving an indication to the surgeon before the beginning of the cancer surgery of where he/she has to position the vascularized graft as a function of the final prosthetic oral rehabilitation.
From this problem, new solutions for the bone reconstruction were created: the scaffolds for the bone regenerative medicine whose use in a near future could substitute the use of the fibula free flap. A chapter describes the new research trend in this area.
The editorial style of this e-book allows updating the data once a year, giving us to publish the more recent findings in the field of the Prosthetically Guided Maxillofacial Surgery

Design and Rapid Manufacturing of anatomical prosthesis for facial rehabilitation
No full textIn this work a novel design and manufacturing procedure have been experimented in order to improve the production of implant-supported nasal prosthesis. The complete workflow was divided into three main steps: data capture, prosthesis design and prosthesis manufacturing. First, the data capturing of the patient’s face was obtained by means of 3D laser scanning. Then, design and manufacturing phases were carried out through CAD–CAM procedures and Rapid Prototyping technologies to obtain the mold for the silicone processing and the substructure for the retention of the prosthesis. Moreover, to design the customized prosthesis based on real anatomic shapes, a novel “Ear&Nose Digital Library” was developed in the framework of a multidisciplinary project with the involvement of students from medicine and engineering faculties. Advantages in terms of improvement of retention and cost reduction are presented
