Nos ltimos anos, a cirurgia virtualmente planeada tem sido progressivamente utilizada na reconstru o de defeitos de maxillectomia e mandibulectomia t o grandes. O conceito de cirurgia assistida por computador utiliza a simula o cir rgica e o desenho tridimensional (3-D) assistido por computador/fabrica o assistida por computador (CAD/CAM), originalmente introduzido para fins de precis o e para diminuir a morbilidade, utiliza ferramentas como guias de corte em vez de depender exclusivamente da aproxima o manual intra-operat ria para a reconstru o facial. O planeamento CAD/CAM para cirurgia ajuda a criar e fabricar dispositivos cir rgicos personalizados para procedimentos como transfer ncias de retalhos livres de osso vascularizado ou como guias cir rgicos para ressecar os defeitos do esqueleto craniomaxilofacial.

In den letzten Jahren wurde die virtuell geplante Chirurgie zunehmend zur Rekonstruktion solch gro er Maxillektomie- und Mandibulektomie-Defekte eingesetzt. Das Konzept der computergest tzten Chirurgie nutzt die chirurgische Simulation und die dreidimensionale (3-D) computergest tzte Planung/Computerfertigung (CAD/CAM), die urspr nglich aus Gr nden der Pr zision und zur Verringerung der Morbidit t eingef hrt wurde und Hilfsmittel wie Schneideschablonen verwendet, anstatt sich bei der Gesichtsrekonstruktion ausschlie lich auf die intraoperative manuelle Ann herung zu verlassen. Die CAD/CAM-Planung f r die Chirurgie hilft bei der Entwicklung und Herstellung ma geschneiderter chirurgischer Ger te f r Verfahren wie vaskularisierte freie Knochentransfers oder als chirurgische Schablonen zur Resektion von Defekten des kraniomaxillofazialen Skeletts.

Au cours des derni res ann es, la chirurgie planifi e virtuellement a t progressivement utilis e pour la reconstruction de ces grands d fauts de maxillectomie et de mandibulectomie. Le concept de chirurgie assist e par ordinateur fait appel la simulation chirurgicale et la conception/ fabrication assist e par ordinateur en trois dimensions (CAO/FAO). Introduite l'origine pour des raisons de pr cision et pour r duire la morbidit , elle utilise des outils tels que des guides de coupe au lieu de s'appuyer exclusivement sur l'approximation manuelle perop ratoire pour la reconstruction faciale. La planification chirurgicale assist e par ordinateur permet de cr er et de fabriquer des dispositifs chirurgicaux personnalis s pour des proc dures telles que les transferts de lambeaux osseux vascularis s ou comme guides chirurgicaux pour r s quer les d fauts du squelette craniomaxillofacial.

Negli ultimi anni, la chirurgia pianificata virtualmente stata progressivamente utilizzata per la ricostruzione di tali ampi difetti di maxillectomia e mandibulectomia. Il concetto di chirurgia assistita dal computer utilizza la simulazione chirurgica e la progettazione/lavorazione tridimensionale (3-D) assistita dal computer (CAD/CAM); originariamente introdotto per la precisione e per ridurre la morbilit , utilizza strumenti come le guide di taglio invece di affidarsi esclusivamente all'approssimazione manuale intraoperatoria per la ricostruzione facciale. La pianificazione CAD/CAM per la chirurgia aiuta a creare e produrre dispositivi chirurgici personalizzati per procedure come i trasferimenti di lembi ossei vascolarizzati o come guide chirurgiche per la resezione dei difetti dello scheletro craniomaxillofacciale.
Correlations of Soil and Rock Properties in Geotechnical Engineering

Correlations of Soil and Rock Properties in Geotechnical Engineering

Jay Ameratunga; Nagaratnam Sivakugan; Braja M. Das

Springer, India, Private Ltd

sidottu
This book presents a one-stop reference to the empirical correlations used extensively in geotechnical engineering. Empirical correlations play a key role in geotechnical engineering designs and analysis. Laboratory and in situ testing of soils can add significant cost to a civil engineering project. By using appropriate empirical correlations, it is possible to derive many design parameters, thus limiting our reliance on these soil tests. The authors have decades of experience in geotechnical engineering, as professional engineers or researchers. The objective of this book is to present a critical evaluation of a wide range of empirical correlations reported in the literature, along with typical values of soil parameters, in the light of their experience and knowledge. This book will be a one-stop-shop for the practising professionals, geotechnical researchers and academics looking for specific correlations for estimating certain geotechnical parameters. The empirical correlations in the forms of equations and charts and typical values are collated from extensive literature review, and from the authors' database.
