“…The patient was quite satisfied with her postoperative outcome. It should be mentioned that we selected cone beam CT for lower dose of radiation and cost 13 since the postoperation CT would not be clinical necessary.…”

Background: To surgically remove osteoma and to keep an optimal cosmetic profile would be very challenging. To solve the difficulty, we utilized the three-dimensional (3D) printing technologies in generating a patient-specific instrument guide (PSIG) for the safe removal of a skull bone tumor. Methods: The preoperational brain computed tomography (CT) provided the digital imaging with thin slices, and then images were reconstructed into a 3D skull model. Based on the model, we designed a PSIG to make landmarks on the osteoma to avoid excessive removal of the skull bone. During the operation, the surgeons could remove the osteoma piece by piece by using the landmark as a reference point. Results: The PSIG was successfully applied to remove an osteoma that measured 60 × 48 × 40 mm 3 over the left frontoparietal skull of a female patient. The 3D CT reconstruction taken both before and 4 months after surgery showed a significant change in the appearance of the osteoma. Conclusion: The PSIG was able to guide the surgeon in the safe removal of the skull osteoma, as well as in maintaining the cosmetic skull profile.

“…In the study, we showed that the digital method was faster in fabricating maxillar (B2= 5.3±0.67) and mandibular (B4= 4.5±0.53) lingual retainer than the conventional method in fabricating maxillar (B1= 20.0±2.91) and mandibular lingual retainers(B3= 9.7±0.67). The digital method is more stable than the conventional method in fabricating the lingual retainer, which was not disturbed by the individual differences or morphological differences of oral tissue or teeth as much as the conventional method [14,15]. The morphological differences among the maxillar upper incisors were more notable than the mandibular lower incisors.…”

The computer-aided designed and manufactured (CAD/CAM) technology is nowadays wildly used in the oral and dental science that provides a stable and efficient way to treat simple and severe disease. The lingual retainer has not change too much until nowadays with the CAD/CAM technology. In this study, we planned to compare the time-consuming and stability of lingual retainer fabricated between conventional method and CAD/CAM method. The results showed that the time for maxilla (B1= 20.0±2.91) and mandible (B3= 9.7±0.67) with conventional method was four times to fabricate the lingual retainer for the maxilla (B2= 5.3±0.67) and mandible ( B4= 4.5±0.53) with CAD/CAM method respectively. These results indicated that the digital method was more efficient in lingual retainer fabrication than conventional method. And while it was more complicated to manufacture lingual retainer for the maxilla than for the mandible, but the conventional method cost twice times to bend the lingual retainer for the maxilla (B1= 20.0±2.91) of the time to bend the lingual retainer for the mandible (B3= 9.7±0.67), while the difference of time-consuming between fabricating the maxilla and mandible was not more than ten percent. All of these indicated that compared with conventional method, the digital method was more efficient and stable which was not disturbed so much by the morphological or individual difference. And it should be the way to deal with the issue of shortage of orthodontists and orthodontic technicians.

ZusammenfassungDefekte im Bereich des Mittelgesichtes sind oftmals nicht nur von funktioneller Bedeutung, auch die ästhetische Komponente solcher angeborenen oder erworbenen Deformitäten beeinträchtigen maßgeblich die Lebensqualität der Patienten. So bedingen Rekonstruktionen des Mittelgesichtes nicht nur lediglich verlorengegangenes oder nicht angelegtes Gewebe zu ersetzen, sondern vielmehr vorhersagbare Ergebnisse sowohl hinsichtlich Ästhtetik als auch Funktion für den individuellen Patienten zu erzielen. Digitale Planungsmöglichkeiten unter Einbeziehung von unterschiedlichen Oberflächen- und Volumendaten in Kombination mit modernen additiven Fertigungstechniken zur Biomodell- und Implantat-Herstellung sowie intraoperativer Unterstützung durch Nutzung realer und virtueller 3D-Volumendaten bei Navigation und intraoperativer Bildgebung aber auch Ergebnissicherung durch postoperative Analyse haben heute in die moderne Mittelgesichtsrekonstruktion Einzug gehalten und setzen neue Standards für die medizinische Versorgung. Ziel dieses Referates ist es im Folgenden die modernen Möglichkeiten der patienten-spezifischen Mittelgesichtsrekonstruktion unter Einbeziehung computer-assistierer Planungs- und Fertigungstechniken darzustellen.
