ESCANEAMENTO DIGITAL E PROTOTIPAGEM 3D PARA CONFECÇÃO DE LAMINADOS CERÂMICOS: RELATO DE CASO CLÍNICO

Abstract

Introduction: laminates  veneers can  be  an  excellent  choice  for  color  correction,  shape, size  and  dental  positioning.  However,  it  is  a technique  that  requires  several  laboratory steps  with  risks  of  distortion  in  the  molding  and  casting  steps  of  the  model.  Thus, maladjustments of laminatesin the mouth may be frequent. Objective: to report a clinical case  of  nine  ceramic  laminates  through  the  digital  scanning,  virtual  punching  and  3D prototyping of the model. Methods: A 59 years old woman showed up to dental clinic searched  dental  care  complaining  of  dental  disproportionality  when  smiling.  At  the clinical  examination,  a  maxillary  inclination  was  observed  that  caused  disharmony.  It was proposed the making of ceramic laminates to compensate the bone discrepancy as well as improve shape, contour and dental color. After the digital planning, preparation diagnostic wax-up, mock up, and acceptance of patient planning, the dental preparations were  started.  After  this  step,  the  teeth  were  scanned  (Trios  3Shape),  punched  and prototyped  in  a  3D  printer.  The  model  was  sent  to  the  laboratory  to  do  the  prosthetic parts in lithium disilicate in an injected and makeup manner. At last, it were made the tests  dry,  wet,  required  adjustments  finally  cementation  of  the  ceramic  laminates  with photopolymerizable resin cement. Conclusions: the technology employed was efficient in solving this case, being a fast technique, which caused little discomfort to the patient and provided a good adaptation of the ceramic laminates.
