Application of computer-aided design and 3D-printed template for accurate bone augmentation in the aesthetic region of anterior teeth

Abstract

Purpose To explore the outcomes of bone augmentation in the aesthetic zone of the anterior teeth using computer-aided design and a 3D-printed template. Methods Ten patients with severe bone defects in the aesthetic zone of anterior teeth were included in the study; CT data were collected before surgery. The design of the osteotomy line in the bone defect area was determined under computer simulation. The position parameters and osteotomy line of the free bone were determined via virtual surgery. A 3D-printed template was prepared to guide the accurate placement of the bone graft. Reexamination was conducted to evaluate the position of the bone graft immediately after the operation and the resorbed capacity of the bone graft before implant restoration. Results The position of the bone graft was consistent with the preoperative design. The amount of bone graft resorbed was within the acceptable range three months after the operation, and the effect of implant restoration was satisfactory. Clinical significance Use of computer-aided design and a 3D-printed template can be an effective approach for accurate bone augmentation in the aesthetic zone of the anterior teeth.

Application of 3D Printing in Bone Grafts

“…A high-performance scaffold underpins the success of a bone tissue engineering strategy, which is a crucial part of the process. The resulting scaffold should be designed with multiple characteristics in mind, including a desirable shape; physical, chemical, structural, and biological features for regenerating complex bone tissues; and enhanced biological performance [ 49 , 140 ]. Magnetic resonance imaging (MRI) and computed tomography (CT) [ 141 , 142 ] provide images of specific defects in an individual patient, and the images can in turn be further used for 3D printing the defective object [ 11 ] ( Figure 3 and Figure 4 ).…”
