Digital duplication of maxillary complete denture: A dental technique

Abstract

ObjectiveThis technique aims to construct a virtual, well‐adapted maxillary denture from an existing, ill‐fitting denture in completely edentulous patients.Clinical ConsiderationsA functional impression is made using the loose maxillary denture, and a cone beam computed tomography (CBCT) of the entire old denture is carried out. The obtained digital imaging and communication in medicine (DICOM) file was segmented using an image computing platform software (3D slicer). The resultant Standard Tessellation Language (STL) file was 3D printed in porcelain white‐like resin, then colored and characterized.ConclusionsThe technique introduces a high‐quality digital denture replicate with good retention, that can replace the traditional duplication technique. It can also be used as a relining method for old dentures. This proposed digital technique reduces the number of clinical appointments while also providing a digital library for future denture manufacture.Clinical SignificanceThe proposed technique offers a high‐quality digital denture replicate that can replace the traditional duplication technique. This digital technique also reduces the number of clinical appointments required for denture duplication.

Digital design of a hybrid bone and tooth-supported surgical guide in patients with unilateral few remaining natural teeth: a dental technique

“…4 ). Use the segmentation panel to convert the bone Dicom file into an STL file on which a surgical guide can be designed [ 14 ]. The segmentation is made by adjusting the bone threshold and using the Select software tool to choose your area of interest only.…”

Effect of Duplication Techniques on the Fitting Accuracy of CAD-CAM Milled, 3D-Printed, and Injection-Molded Mandibular Complete Denture Bases

“…Digital denture duplication has been investigated in previous studies [12][13][14][15][16][17][18]. Clark et al [12] reported that the digital replication technique of the exciting prosthesis is a proven technique with decreased laboratory steps and required chair time compared with conventional methods.…”

“…Chen et al [1] compared the accuracy of digitally duplicated dentures to conventionally duplicated ones and concluded that the digital technique showed high accuracy and effectiveness. Fekri et al [16], compared, an ill-fitting maxillary denture duplicate with a well-fitted digitally duplicated denture and reported that digital duplication is a promising alternative to conventional duplication techniques. Alehaideb et al [17], compared different desktops and intraoral scanners for digital denture duplication and concluded that all the scanners could duplicate dentures with high accuracy.…”

“…In another study after creating a standard tessellation language (STL) file, dentures were duplicated using CAD-CAM milling and additive methods [12,13]. Although several studies [12][13][14][15][16][17] have assessed different techniques for digital denture duplication, different scanners, or provided a case report validating specific dental techniques, no studies have compared denture base materials and fabrication technologies in relation to digital denture duplications.…”
