Introduction: Many advanced techniques and materials have been introduced in the recent years with the advent of the new designing technology. Hence, in our study, we aimed to compare in maxillofacial trauma, the three-dimensional (3D) plating systems.
Materials And Methods: We piloted a prospective clinical study among 50 subjects of both genders with mandibular parasymphysis fracture. We compared the 3D miniplates with the two-dimensional (2D) miniplates where the subjects were divided into 2 groups equally. The clinical parameters were compared at different times of follow-up after the surgery.
Results: We observed that there was a similar distribution of the genders and the side of the fracture of the parasymphysis. There was a significant difference between the groups for the mouth opening while there was no significant difference for the sensory deficit. The subjects recovered better with the 3D mini-plates.
Conclusion: The mandibular fractures can be successfully treated with the 3D miniplates that help in a quick and efficient recovery.

A three-dimensional numerical model of the vacuum sintering furnace was established, combined with the custom program of temperature-voltage feedback regulation. Through simulationand experimental validation, the heating and holding stage as well as the thermal hysteresis phenomenon of the furnace were analyzed, a dimensionless quantity of hysteresis temperature difference was proposed and calculated, the distribution of the electric field and temperature uniformity of the furnace were discussed in detail, while the structural improvement approach was proposed based on simulation. The results show that: during the heating process, the maximum of thermal hysteresis temperature difference between the graphite cylinder and the heating tube is 0.

Digital orthodontics has been integrated into NasoAlveolar Molding (NAM) therapy to overcome challenges in the conventional NAM method. This study introduced an individualized Digital NAM (iDNAM) and evaluated the changes in the alveolar ridges and nasolabial morphology after iDNAM treatment. Prospective data were collected from 15 infants with complete unilateral cleft lip and palate who underwent iDNAM therapy.

Objectives: The aim of the present study is to evaluate the accuracy of a digital template on the three-dimensional accuracy of edentulous implantation through a retrospective study to provide more clinical evidence for the use of digital templates in edentulous patient.
Materials And Methods: This study evaluates the efficacy of a digital surgical template in edentulous jaws, comparing preoperative plans with postoperative outcomes across four metrics: platform, apex, depth, and angular deviations. Utilizing a patient with an edentulous maxilla as a case study, this research employs CBCT for preoperative and postoperative assessments, with deviations analyzed via 3-Shape software.

Objective: Calcaneal fracture fixation remains a challenging procedure in orthopedics, with computational tools increasingly aiding in the optimization of preoperative planning. To compare the biomechanical stability of intramedullary fixation and locking plate fixation for Sanders II and III calcaneal fractures by three-dimensional (3D) finite element analysis and to provide a theoretical basis for clinical application.
Methods: The Computed Tomography (CT) images were segmented using Mimics software (Materialise NV, Belgium) to identify the region of interest based on threshold segmentation.

The rates of recovery of spontaneous circulation, admission survival, and discharge survival of out-of-hospital cardiac arrest (OHCA) patients in China are much lower than the world and Asian averages, and the data on the survival of in-hospital cardiac arrest (IHCA) patients are also less favorable. The variable quality of cardiopulmonary resuscitation (CPR) and the low percentage of bystander CPR participation are the main reasons for these phenomena. Real-time feedback devices are an effective strategy to address these issues and have been recommended for use in several guidelines.
