This book serves as a comprehensive guide to Cone Beam Computed Tomography (CBCT), focusing on its fundamental physics, anatomical landmarks, and multifaceted applications in various fields of dentistry and medicine. It bridges the gap between theory and practical implementation, making it an essential resource for students, professionals, and researchers. The reader will gain a thorough understanding of how CBCT works, including its ability to generate high-resolution 3D images from multiple X-ray projections, which enables precise visualization of structures not visible through conventional 2D radiography. This technical foundation sets the stage for a deeper appreciation of how CBCT contributes to various fields.

"Dist rbios neuromusculares" refere-se a uma variedade de condi es que prejudicam a fun o muscular, quer directamente atrav s de patologias do m sculo volunt rio, quer indirectamente atrav s de patologias do sistema nervoso perif rico ou de jun es neuromusculares. Outras doen as da medula espinal ou do c rebro n o s o classificadas como "neuromusculares". Tem um efeito sobre os nervos que controlam os m sculos volunt rios. Os m sculos volunt rios, como os que est o dentro dos bra os e pernas, s o frequentemente controlados. As mensagens que controlam estes m sculos s o enviadas por c lulas nervosas, tamb m conhecidas como neur nios. A comunica o entre o sistema nervoso e os m sculos perturbada quando os neur nios se tornam insalubres ou morrem. Devido a isto, os m sculos tornam-se fracos e desperdi am-se. Tremores, c ibras, dores e dores, bem como problemas de articula o e movimento, podem ser sintomas de fraqueza. Pode tamb m ter um impacto no funcionamento do cora o e na respira o. As doen as neuromusculares cl ssicas s o classificadas como doen as que envolvem neur nios motores nas cordas cranianas e espinais, ra zes nervosas espinais, plexos nervosos, nervos perif ricos, jun es neuromusculares, e/ou m sculos com base na sua localiza o.

Der Begriff "neuromuskul re St rungen" bezieht sich auf eine Vielzahl von Erkrankungen, die die Muskelfunktion beeintr chtigen, entweder direkt durch Pathologien des willentlichen Muskels oder indirekt durch Pathologien des peripheren Nervensystems oder der neuromuskul ren Verbindungsstellen. Andere Erkrankungen des R ckenmarks oder des Gehirns werden nicht als "neuromuskul r" eingestuft. Sie wirken sich auf die Nerven aus, die die willk rlichen Muskeln steuern. Willk rliche Muskeln, wie die in Armen und Beinen, werden h ufig kontrolliert. Die Nachrichten, die diese Muskeln steuern, werden von Nervenzellen, auch Neuronen genannt, gesendet. Die Kommunikation zwischen dem Nervensystem und den Muskeln ist gest rt, wenn die Neuronen erkranken oder absterben. Infolgedessen werden die Muskeln schwach und verk mmern. Zuckungen, Kr mpfe, Schmerzen sowie Gelenk- und Bewegungsprobleme k nnen Symptome einer Schw che sein. Sie kann auch Auswirkungen auf die Herzfunktion und die Atmung haben. Klassischerweise werden neuromuskul re Erkrankungen als St rungen klassifiziert, die motorische Neuronen im Hirn- und R ckenmark, in den Spinalnervenwurzeln, in den Nervengeflechten, in den peripheren Nerven, in den neuromuskul ren Knotenpunkten und/oder in den Muskeln betreffen.

" Troubles neuromusculaires " d signe une vari t d'affections qui alt rent la fonction musculaire, soit directement par des pathologies du muscle volontaire, soit indirectement par des pathologies du syst me nerveux p riph rique ou des jonctions neuromusculaires. Les autres maladies de la moelle pini re ou du cerveau ne sont pas class es comme "neuromusculaires". Elles ont un effet sur les nerfs qui contr lent les muscles volontaires. Les muscles volontaires, comme ceux des bras et des jambes, sont souvent contr l s. Les messages qui contr lent ces muscles sont envoy s par des cellules nerveuses, galement appel es neurones. La communication entre le syst me nerveux et les muscles est perturb e lorsque les neurones deviennent malsains ou meurent. De ce fait, les muscles s'affaiblissent et se d t riorent. Les contractions, les crampes, les courbatures et les douleurs, ainsi que les probl mes d'articulation et de mouvement, peuvent tous tre des sympt mes de faiblesse. Elle peut galement avoir un impact sur la fonction cardiaque et la respiration. Classiquement, les maladies neuromusculaires sont class es comme des troubles impliquant les neurones moteurs dans les moelles cr nienne et pini re, les racines des nerfs rachidiens, les plexus nerveux, les nerfs p riph riques, les jonctions neuromusculaires et/ou les muscles en fonction de leur localisation.

Per "disturbi neuromuscolari" si intende una serie di condizioni che compromettono la funzione muscolare, direttamente attraverso patologie del muscolo volontario o indirettamente attraverso patologie del sistema nervoso periferico o delle giunzioni neuromuscolari. Altre malattie del midollo spinale o del cervello non sono classificate come "neuromuscolari". Hanno un effetto sui nervi che controllano i muscoli volontari. I muscoli volontari, come quelli delle braccia e delle gambe, sono spesso controllati. I messaggi che controllano questi muscoli sono inviati dalle cellule nervose, note anche come neuroni. La comunicazione tra il sistema nervoso e i muscoli si interrompe quando i neuroni si ammalano o muoiono. A causa di ci , i muscoli diventano deboli e si indeboliscono. Contrazioni, crampi, dolori, problemi articolari e di movimento possono essere sintomi di debolezza. Pu anche avere un impatto sulla funzione cardiaca e sulla respirazione. Classicamente le malattie neuromuscolari sono classificate come disturbi che coinvolgono i motoneuroni dei cordoni cranici e spinali, le radici dei nervi spinali, i plessi nervosi, i nervi periferici, le giunzioni neuromuscolari e/o i muscoli in base alla loro localizzazione.

"Neuromuscular Disorders" refers to a variety of conditions that impair muscle function, either directly through pathologies of the voluntary muscle or indirectly through pathologies of the peripheral nervous system or neuromuscular junctions. Other diseases of the spinal cord or brain are not classified as "neuromuscular." It has an effect on the nerves that control voluntary muscles. Voluntary muscles, like those within the arms and legs, are often controlled. The messages that control these muscles are sent by nerve cells, also known as neurons. Communication between the nervous system and muscles is disrupted when neurons become unhealthy or die. Due to this, muscles become weak and waste away. Twitching, cramps, aches, and pains, as well as joint and movement problems, can all be symptoms of weakness. It can also have an impact on heart function and breathing. Classically neuromuscular diseases are classified as disorders involving motor neurons in the cranial and spinal cords, spinal nerve roots, nerve plexuses, peripheral nerves, neuromuscular junctions, and/or muscles based on their location.
