Purpose: The aim of this study was to conduct a systematic review and meta-analysis to evaluate the influence of cantilevers upon implant-supported fixed partial dentures on marginal bone loss (MBL) and prosthetic-related complications.
Materials And Methods: An electronic literature search was conducted in the PubMed database by two reviewers (LTM and AM) for articles written in English from June 2003 to January 2013 that were prospective human clinical trials with the clear purpose of appraising the effect of implant-supported fixed partial prostheses on peri-implant bone level and prosthetic complications. Data from the selected studies were extracted to carry out the statistical analysis.
Results: Following the method described earlier, from initial research of 643 studies, 4 human clinical studies met the inclusion criteria and provided enough data to include them in the present meta-analysis. For the overall data, the pooled weighted mean (WM) of the MBL was 0.72 mm (range, 0.49 to 1.10 mm), with a 95% confidence interval (CI) of 0.36 to 1.08 mm. For the chi-square test, P = .60, representing a low heterogeneity among studies. MBL around implant-supported restorations with and without cantilevers was not found to be significant between both groups. The weighted mean difference (WMD) was 0.10 mm (favoring the non-cantilever group), with a 95% CI = -0.18 to 0.39 mm (P = .47). For the chi-square test, P = .97, also indicating a low degree of heterogeneity between the studies.
Conclusion: The dearth of scientific evidence in this matter does not permit clear conclusions to be drawn. However, within the limitations, marginal bone loss does not seem to be influenced by the presence of cantilever extensions. Moreover, minor technical complications were found when a cantilever was present when compared to the control groups.

Facial nerve dysfunction (FND) is a well-recognized but poorly documented complication of mandibular distraction osteogenesis (MDO) for Robin sequence (RS). This study aims to document the authors' experiences with FND and identify risk factors associated with this adverse event. A retrospective review of a prospectively gathered database was performed to identify patients with RS who underwent MDO at the authors' institution from March 2016 to June 2023.

Ewing sarcoma family tumors (ESFT) pose diagnostic challenges, which largely depend on the primary site of involvement and tumor stage. Despite advancements in treatment, metastatic ESFTs remain associated with poor outcomes. This case describes a 21-year-old woman who, in July 2022, presented with a left breast mass identified through ultrasound and CT scan, along with abdominal distention.

Background And Purpose: This study investigates the practicality and utility of the "outline sign," which refers to the thin curvilinear hyperenhancing line that may be seen along the margin of a meningioma on a spin-echo postcontrast T1-weighted image. For cases in which the differential diagnosis may include other tumors, visualization of the outline sign may help to increase the diagnostic confidence for a meningioma. Therefore, in the temporal bone region such as the cerebellopontine angle or jugular foramen, where differential considerations may include a schwannoma or paraganglioma, we additionally investigated whether the outline sign may be observed in these nonmeningioma lesions.

Background: Unilateral cleft lip secondary nasal deformities are common and require surgical correction frequently. The nasal dome on the cleft side is depressed, and the nasal ala is in an extended and flattened position compared with the noncleft side. In addition, the nasal septum is deviated into the cleft nostril.

Objective: The aim of this study was to compare image quality features and lesion characteristics between a faster deep learning (DL) reconstructed T2-weighted (T2-w) fast spin-echo (FSE) Dixon sequence with super-resolution (T2) and a conventional T2-w FSE Dixon sequence (T2) for breast magnetic resonance imaging (MRI).
Materials And Methods: This prospective study was conducted between November 2022 and April 2023 using a 3T scanner. Both T2 and T2 sequences were acquired for each patient.
