A Cone-Beam Computed Tomography x-ray (PaX-i3D Green; VATECH), with parameters of 120 kVp,37.07 MAs, and a 0.25 mm voxel size, was performed for each patient to obtain Digital Imaging and Communication in Medicine (DICOM) file. Intraoral scanning for both working and opposing arches, along with digital bite registration, was carried out using the (MEDIT i600; MEDIT Corp.) to create a standard tessellation language (STL) file.A tooth-supported surgical guide was designed according to the prosthetically driven implant placement concept. The design of temporary restorations was carried out using (Exocad, Dental CAD software) after virtual extraction of the non-restorable anterior tooth [
Virtual designing of the temporary prosthesisAfter superimposition of the patient’s STL and DICOM files using (Real guide 5.0 software 3DIEMME), and according to the bone width, length, and socket dimensions, the implants (implant direct Legacy; Malibu Hills Road, Calabasas Hills, CA, USA) with a diameter of (3.7–4.2 mm) and a length of (13–16 mm) were selected.

Design of the implant placement surgical guideThe surgical guides and the temporary restorations were 3D printed using (clear resin, EPAX resin for the EPAX 3d printer) and (white porcelain-like resin, EPAX resin for the EPAX 3D printer), respectively.
