Una polpa esposta, a causa della degenerazione delle strutture dentinali dovuta alla carie o a un trauma, tende a innescare meccanismi protettivi che sono la diminuzione della permeabilit dentinale, la formazione di dentina terziaria e una reazione infiammatoria e immunitaria. Esiste una relazione simbiotica tra la dentina e la polpa e quindi la gestione della polpa esposta pu essere realizzata con una procedura di pulp capping. L'obiettivo di tutte le strategie di trattamento della polpa vitale quello di creare uno stato che consenta la formazione di una barriera di tessuto duro e il recupero del tessuto, preservando la funzionalit e quindi garantendo la permanenza a lungo termine del dente vitale nella cavit orale.

Eine freiliegende Pulpa, entweder durch Degeneration der dentinalen Strukturen durch Karies oder durch ein Trauma, neigt dazu, Schutzmechanismen in Gang zu setzen, n mlich eine Verringerung der dentinalen Permeabilit t, die Bildung von terti rem Dentin und eine Entz ndungs- und Immunreaktion. Es besteht eine symbiotische Beziehung zwischen Dentin und Pulpa, und daher kann das Management der freiliegenden Pulpa durch ein Pulpa-Capping-Verfahren erreicht werden. Das Ziel aller Strategien zur Behandlung der vitalen Pulpa ist es, einen Zustand zu schaffen, der die Bildung einer Hartgewebsbarriere und die Wiederherstellung des Gewebes erm glicht, so dass die Funktionalit t erhalten bleibt und somit sichergestellt wird, dass ein vitaler Zahn langfristig in der Mundh hle bleibt.

An exposed pulp, either by degeneration of dentinal structures by caries or trauma will tend to initiate protective mechanisms which are, a decrease in dentinal permeability, formation of tertiary dentin and, an inflammatory and immune reaction. There is a symbiotic relation between dentin and the pulp and hence management of exposed pulp, can be accomplished by pulp capping procedure. The objective of all vital pulp treatment strategies is to create a state that enables the formation of a hard tissue barrier and the recovery of tissue, preserving the functionality and therefore ensuring that a vital tooth remains in the oral cavity long-term.

In the field of dentistry 3D printing is entrenching itself as an advancing forefront. Additive manufacturing, or 3D printing, is becoming a viable alternative to subtractive manufacturing, or milling in the field of computer-aided manufacturing. Material research for use in additive manufacturing is ongoing, and a wide range of materials are being used or developed for use in dentistry. Digital technology and 3D printing have significantly elevated the rate of success, improving the quality and accuracy of dental treatment. Educational programs that use 3D printed models encourage students and trainees to improve their dental expertise. This book aims to review the various 3D printing techniques, materials for fabricating models, and applications in dentistry.
