Abstract

Abstract Guided bone regeneration (GBR) represents the gold standard to reconstruct alveolar bone and peri-implant rehabilitation. 1 The key principle of GBR is the use of membrane to exclude non-osteogenic tissues from interfering with bone regeneration. Membranes must have some characteristics such as biocompatibility, tissue integration cell-occlusion properties, and space making ability. 2 Titanium mesh is a non-resorbable membrane with good space-making effect and frequently combined with grafting materials. 3 However, titanium mesh exposure is one of the common complications. Recently, three-dimensional (3D) printing model is increasingly used in oral and maxillofacial reconstruction surgery for creating custom cutting guides, fixation devices, practice models, and implanted medical devices to improve the treatment outcome. Prior to surgery, titanium mesh pre-formed on a 3D printing model could make the shape of titanium mesh more precise and accuracy for shortening the operation time. 4
