Summary: A detailed understanding of craniofacial ontogenetic development is crucial in various scientific disciplines. This study aimed to construct a facial aging model, evaluate the aging effect on facial form and important dimensions, and monitor the development of facial sexual dimorphism. The findings showed both common traits and sexual dimorphic changes during the aging process.

Summary: The aim of this study is to provide a new method for performing Enlow's neutral track analysis on cone-beam computed tomography (CBCT) images. The validity of the proposed 3D analysis method was confirmed by comparing it with the traditional 2D analysis on lateral cephalograms. Further studies are needed to validate these results with a larger sample and different skeletal class subjects.

Summary: In this study, the geometric and physical methods related to soft tissue modeling were investigated. For geometric modeling, the problem of repeated inverse calculations of control points in the Bezier method was solved via re-parameterization, which improved the calculation speed. Regarding physical modeling, the fitting ability of the particle spring model to the anisotropy of soft tissue was improved by optimizing the topological structure of the model and introducing a dynamic elastic coefficient parameter.

Summary: This article introduces a method for manufacturing hydrogel electronics using 3D printing technology. By using a special hydrogel supporting matrix and silver-hydrogel ink, complex 3D circuits can be created within the hydrogel matrix. The resulting hydrogel electronics are soft, stretchable, and exhibit high conductivity.

Summary: A pilot study was conducted using patient-derived 3D cell cultures to investigate the effects of photon and proton radiation on different subtypes of localized high-grade soft tissue sarcoma (STS). The study found pronounced differences in radiosensitivity among different subtypes of STS, and showed that photon and proton radiation had similar dose-dependent cell-killing effectiveness in the 3D cell cultures.

Summary: This study aimed to evaluate the precision and accuracy of single-camera photogrammetry (SCP) and multicamera photogrammetry (MCP) compared to direct anthropometry (DA). The results showed that SCP and MCP techniques were reliable and valid options for 3D facial imaging. SCP produced slightly larger mean values for some measurements, but the differences were within a clinically acceptable range. Caution should be exercised when assessing measurements in the gonial area and subnasale due to larger margins of error.

Summary: This study validated the reproducibility of 46 facial soft-tissue landmarks in 3D imaging, showing that the majority of landmarks are reproducible within 1mm and can be used as reference points in future clinical practice. The study included European Caucasian and Chinese volunteers and found that there were slight differences in landmark reproducibility between Caucasians and Asians in certain regions.

Summary: To overcome the challenges of inspecting patients' soft tissues and measuring the effects of dental procedures on their facial physiognomy, facial scanning and computer measurement techniques were used. The 3D face scans obtained with a low-cost scanner showed high accuracy and repeatability. Computational measurements proved to be accurate, repeatable, and comparable to actual measurements. The use of 3D facial scans as a faster and more comfortable technique can help detect and quantify changes in facial soft tissue resulting from dental procedures.

Summary: This protocol outlines how to utilize atomic force microscopy for measuring the elastic modulus of soft 2D surfaces and cell-laden 3D hydrogels. It includes instructions for sample preparation, instrument calibration, data collection and analysis, and inferring differential matrix remodeling activity in hydrogels. The protocol is suitable for probing a variety of synthetic and naturally derived polymeric hydrogels and allows users to characterize the mechanical properties of multiple surfaces or hydrogels in a single day with introductory AFM training.

Summary: This study investigated the relationship between skeletal and soft tissue changes after incisor retraction in patients with Angle Class I bimaxillary dentoalveolar protrusion. The results showed a significant correlation between skeletal point A and soft tissue point A on the anteroposterior axis. However, changes in incisor tip, apex, and inclination did not significantly affect the position of skeletal points A and B. It is important to consider both hard and soft tissue analysis in treatment planning for malocclusion.

Summary: The study found that the midpalatal suture density ratio (MPSD) obtained from pre-treatment scans is not an effective predictor of long-term skeletal expansion after Rapid Maxillary Expansion (RME). There was no statistically significant correlation between MPSD and skeletal expansion, indicating that MPSD is not a reliable indicator for predicting skeletal changes following RME treatment.

Summary: This study quantified the annual transverse growth of the maxilla using skeletal landmarks on CBCT scans in both male and female child and adolescent patients. The distances between landmarks increased significantly with growth, and males generally exhibited greater annual changes compared to females, though correlations with patient age were not significant.

Summary: This study used cone-beam computed tomography scans to measure changes in orbital volume from childhood to the late teenage years. Results showed that orbital volume increases by 1-2% annually until the late teenage years. This finding is clinically relevant, as it may affect surgical outcomes for reconstructive surgery in pediatric anophthalmic sockets.

Summary: In this study, the outcomes of patients with Class II malocclusion treated with the cervical pull face-bow headgear appliance in combination with full fixed orthodontic appliances were quantified and compared. The results showed that Class II skeletal correction was mainly achieved by posterior and inferior displacement of the maxilla, while the mandibular position did not significantly change.
