Experimental Validation of Plastic Mandible Models Produced by a "Low-Cost" 3-Dimensional Fused Deposition Modeling Printer.

Background: The objective of this study was to investigate the accuracy of 3-dimensional (3D) plastic (ABS) models generated using a low-cost 3D fused deposition modelling printer.

Material/methods: Two human dry mandibles were scanned with a cone beam computed tomography (CBCT) Accuitomo device. Preprocessing consisted of 3D reconstruction with Maxilim software and STL file repair with Netfabb software.

Suspension sutures in facial reconstruction: surgical techniques and medium-term outcomes.

The purpose of this study was to assess the medium-term results of using thread-lift sutures as a means to support soft tissues in facial reconstructive surgery. The rationale for the introduction of this method was to provide support for tissues used in the reconstruction in cases where this would otherwise have been difficult to achieve, or would have demanded major additional surgery in patients already undergoing major surgical procedures. The outcome of the procedure was assessed 12 and 24 months after surgery.
