A set of novel finite element models of surgically assisted rapid palatal expansion (SARPE) that could perform a clinically required amount of expander activation with various angles of buccal osteotomy was created for further analysis of the expansion patterns of the hemimaxillae in all three dimensions.

The zebrafish maxillary barbel is an integumentary sense organ containing ectodermal, mesodermal and neural crest derivatives. Importantly, the adult barbel can regenerate after proximal amputation. This video introduces maxillary barbel development and demonstrates a surgical protocol to induce regeneration, followed by collection, embedding and downstream imaging of barbel specimens.

Source: J. Jacob Chavez, Ryan T. Davis, and Taylor D. Sparks, Department of Materials Science and Engineering, The University of Utah, Salt Lake City, UT Thermal expansion is extremely important when considering which materials will be used in systems that experience fluctuations in temperature. A high or low thermal expansion in a material may or may not be desirable, depending on the application. For instance, in a common liquid thermometer, a material with a high thermal expansion would be...

Here we demonstrate step-by-step a manageable, orthodontic tooth movement protocol operated on a murine maxillary model. With the explicit explanation of each step and visual demonstration, researchers can master this model and apply it to their experimental needs with a few modifications.
FAQs
Expansion depends on how applied lateral force is transferred through the maxilla. An orthodontic expander loads the upper jaw and teeth, producing a widening response that may include skeletal change, dental movement, or both. In growing patients, the force can separate the midpalatal suture, making the interaction between device loading and craniofacial growth central to treatment behavior.
Skeletal widening reflects change in the maxillary bones, whereas dental expansion reflects movement of teeth within the arch. Maxillary expansion can involve either contribution, and the applied force may affect both. Separating these components helps bioengineers analyze how a device produces its measured increase in transverse width and helps clinicians interpret the resulting arch form.
Growth status matters because the midpalatal suture can separate in growing patients, followed by new bone formation during healing. That sequence links mechanical loading with biological remodeling rather than tooth movement alone. Consequently, growth is an important condition in models of craniofacial mechanics and in decisions about how expansion should be planned for an individual patient.
The central feature is the expander’s ability to apply controlled lateral forces to the upper jaw and teeth. In bioengineering, that loading behavior connects device design with tissue mechanics and the resulting pattern of skeletal and dental change. Studying this relationship can support more informed device development and patient-specific orthodontic treatment planning.
Clinically, maxillary expansion can help correct posterior crossbite, improve coordination between the dental arches, and address constricted nasal or oral spaces. These goals show that the approach is not limited to increasing width alone. Its value is assessed through how the altered transverse relationship supports arch form and overall orthodontic treatment objectives.
Patient-specific planning should consider the desired transverse width, dental arch form, and the presence of constricted nasal or oral spaces. It should also account for whether expansion is expected to involve the maxillary bones, the teeth, or both. These factors connect anatomical goals with the selection and use of an appropriate orthodontic expander.
Maxillary expansion provides a focused bioengineering model because it combines an applied device force with bone remodeling, tissue mechanics, and craniofacial growth. Researchers can therefore examine how mechanical loading produces changes in skeletal and dental structures, while treatment planners can use the same framework to relate patient anatomy to expansion goals and device design.
