Much of the burden of living with a disability is concentrated among those populations least financially able to bear the burden. As the price of 3 dimensional (3D) printing decreases, individual access to this technology increases. 3D-printed prostheses can be designed specifically for use in resource-poor settings, including developing countries, to minimize the cost of consumable parts while optimizing durability in harsh environmental conditions.

Objective: This study presents a novel digital interproximal enamel reduction (IER) clinical procedure, aiming to improve the effectiveness of IER processes in orthodontic treatment.
Methods: A malocclusion case of skeletal-class I and angle-class I was selected for the experimental investigation. A three-dimensional (3D) model of the dentition was constructed using scanning data from a plaster model.

This study aims to evaluate and compare the usability and performance of mixed reality (MR) technology versus conventional methods for preoperative planning of patient-specific reconstruction plates for orbital fractures. A crossover study design was used to compare MR technology with conventional three-dimensional (3D) printing approaches in the planning of maxillofacial traumatology treatments. The primary focus was on user-friendliness and the accuracy of patient-specific reconstruction planning.

Objective: Guided implant surgery using three-dimensional (3-D) planning software and 3-D printed surgical guides has become a critical tool for enhancing accuracy. This study aims to determine the minimum guide hole height necessary to maintain implant placement accuracy.
Materials And Methods: Ten maxillary models with edentulous areas were created using CT and optical scan data.
Purpose: To create tridimensional (3D) anatomical models of diaphyseal fractures in dogs (3D AMDFD) and to evaluate the models from their radiographs.
Methods: The study consisted of six stages: preparation of femur from a healthy dog cadaver; digitalization of the bone through a 3D scanner and creation of the base model; creation of a 3D AMDFD based on the image of the base model, 3D modeling carried out to reproduce five different types of diaphyseal fractures; printing the models produced on a 3D printer with a thermoplastic material; insertion of neodymium magnets in the fracture line to allow the assembly and disassembly of the parts; and radiography of 3D AMDFD in lateromedial and craniocaudal positions.
Results: The base model and 3D AMDFD had high precision in the replication of bone structures, like the bone in natura.
