Localised alveolar ridge defect refers to volumetric deficit of the limited extent of bone and soft tissue within the alveolar process. Such type of ridge defects can be corrected by surgical ridge augmentation that can be accomplished by the addition of either soft or hard tissues. The contour of a partially edentulous ridge should be thoroughly evaluated before a fixed partial denture is undertaken. The ideal ridge width and height allows placement of a natural appearing pontic which provides maintenance of a plaque-free environment. This article describes a procedure of surgical ridge augmentation of a localised alveolar ridge defect in the maxilla, followed by fixed partial denture, enhancing the aesthetics, function and health.

Unlabelled: Zika virus (ZIKV) infection can lead to a variety of clinical outcomes, including severe congenital abnormalities. The phosphatidylserine (PS) receptors AXL and TIM-1 are recognized as critical entry factors for ZIKV . However, it remains unclear if and how ZIKV regulates these receptors during infection.

Alveolar ridge loss presents difficulties for implant placement and stability. To address this, alveolar ridge preservation (ARP) is required to maintain bone and avoid the need for ridge augmentation using socket grafting. In this study, a scaffold for ARP was created by fabricating a 3D porous dense microfiber silk fibroin (mSF) embedded in poly(vinyl alcohol) (PVA), which mimics the osteoid template.

Background and objective Alveolar ridge defects in partially edentulous patients present significant challenges in prosthodontic treatment planning. Seibert's classification system provides a structured approach to categorizing these defects based on the buccolingual and apico-coronal dimensions of the ridge. Accurate classification is crucial for determining appropriate treatment strategies for implant placement, fixed prosthesis, or tissue augmentation.

Epithelial-mesenchymal transition (EMT) is implicated in the pathogenesis of silicosis. High mobility group box 1 (HMGB1) has been found to induce EMT in fibrotic diseases. Previous studies have revealed a critical role of HMGB1 in silicosis, whereas the detail mechanisms still obscure.

Background: The stability of soft and hard tissues surrounding the implant is not only a matter of aesthetics, but also affects the long-term stability of the implant. The present study was to explore the influence of buccal mucosa width/height (W/H) ratio, emergence profile and buccal bone width on peri-implant soft and hard tissue changes in the posterior region.
Methods: Fifty-eight posterior implant restoration cases were recruited in this study.
