The clinical database and the complex esthetic cases used in digital PBL-CBL method
bone block
Twenty-six cases with one to six teeth missing in the anterior maxilla were included as the clinical information database for digital PBL-CBL method. In fifteen cases, 3D printed titanium meshes were fabricated for guided bone regeneration. Four patients received onlay bone block grafting under the assistance of 3D printed surgical guide. Eighteen patients underwent second bone augmentation simultaneously with dental implant placement at T2. Six patients received connective tissue grafting before soft tissue conditioning. These cases can cover all the techniques and theoretical knowledge in courses of esthetic implant therapy. A case of guided bone regeneration under the guidance of 3D printed titanium mesh was displayed below to show the digital workflow in detail.The patient was a 26-year-old female patient who had #23 tooth extracted 5 years ago. A clinical exam revealed good oral hygiene and a normal smile line (
