AI Article Synopsis
- The study investigated how static teeth exposure changes in different positions (upright vs. supine) among patients who had orthognathic surgery.
- It involved 148 patients, measuring teeth exposure before and after surgery, with results showing a significant difference of 0.99 mm when lying down compared to standing.
- The findings indicated that the difference in teeth exposure was more pronounced in males, while factors like orthodontic brackets, surgery timing, and age did not significantly impact the results.
Article Abstract
Objectives: This study aimed to explore the differences and influencing factors of static teeth exposure in different postures of orthognathic surgery patients.
Methods: A total of 148 patients were collected before or after orthognathic surgery. Photographs were taken in the upright and supine positions, and the static teeth exposure values were measured to compare whether the difference among different positions was statistically significant. The patients were classified in accordance with gender, presence or absence of orthodontic brackets, measurement time (preoperative or postoperative), and maxillary movement direction (forward or backward), and the difference of static teeth exposure was compared. The correlation between the difference of static teeth exposure and age was analyzed.
Results: The diffe-rence of static teeth exposure between the two positions was 0.99 mm±0.95 mm, which was statistically significant (=0.000). A statistical difference in the difference of static exposure was observed between female and male (0.05). No statistical difference in the difference of static exposure was observed among orthodontic brackets, preoperative or postoperative time points, and maxillary movement direction. In addition, no significant correlation was found between the difference of static teeth exposure and age (=-0.087, =0.291).
Conclusions: Compared with the upright position, the static exposure of teeth increased by approximately 0.99 mm in the supine position. The difference of static exposure under different postures was greater in males than in females. Furthermore, orthodontic bracket, maxillary surgery, maxillary movement direction, and age had no effect on the difference of static teeth exposure in different postures.

Oxidative stress (OS) is a common feature of many inflammatory diseases, oral pathologies, and aging processes. The impact of OS on periodontal ligament cells (PDLCs) in relation to oral pathologies, including periodontal diseases, has been investigated in different studies. However, its impact on orthodontic tooth movement (OTM) remains poorly understood.

: Achieving ideal anchorage is crucial in orthodontics for controlled tooth movement. Miniscrews (MSs) have improved skeletal anchorage, but freehand placement poses risks like root damage and limited precision. Guided techniques, including radiographic guides and computer-assisted methods (static [sCAS] and dynamic [dCAS]), were developed to enhance accuracy and safety.

Pulp chamber and root canal obliteration (PCO/RCO) presents a challenge for clinicians when nonsurgical endodontic treatment is indicated. Guided endodontics (GE) aims to precisely locate the root canal (RC) system while preserving as much pericervical dentin as possible. GE involves integrating cone-beam computed tomography (CBCT) of the affected tooth with a digital impression of the maxillary/mandibular arch, allowing for careful planning of the drilling path to the RC system through a three-dimensional (3D) static guide.

Purpose: Restoring ferrule-lacking, noncircular canal endodontically treated teeth (ETT) poses challenges owing to the increased susceptibility to root fracture and post dislodgement. We aimed to evaluate the influence of different post and core materials on the stress distribution and maximum Von Mises stress in ETT.
Methods: Four three-dimensional models were generated using different customized post and core materials: gold alloy, resin nanoceramic, polyetheretherketone (PEEK), and polyetherketoneketone (PEKK).
The glycerol stabilized calcium phosphate cluster for rapid remineralization of tooth enamel by a water-triggered transformation.

Remineralization is a common strategy for the repair of early demineralized tooth enamels, but the harsh dynamic oral environment often hampers its efficacy. Rapid remineralization is expected to address this challenge, however, the stabilizers of remineralization materials often resist their transformation required for repair. Here, by dissolving the ions of calcium and phosphate in glycerol-dominant solvents, we obtain the calcium phosphate clusters (1-2 nm), which are stabilized by glycerol (with high viscosity and affinity to clusters), but can perform a fast enamel repair via the water-triggered transformation in both static and dynamic environments.
