Subperiosteal peri‐implant augmented layer to correct bone dehiscence at immediate implant placement

Clinical Advances in Periodontics, EarlyView.
Abstract Background The purpose of the present case report is to describe the potential of the subperiosteal peri‐implant augmented layer (SPAL) technique in peri‐implant bone dehiscence (PIBD) correction at immediate implant placement (IIP). Methods This case report describes the application of the SPAL technique in two patients undergoing IIP at ...

Trans${^2}$-CBCT: A Dual-Transformer Framework for Sparse-View CBCT Reconstruction

CoRR
Cone-beam computed tomography (CBCT) using only a few X-ray projection views enables faster scans with lower radiation dose, but the resulting severe under-sampling causes strong artifacts and poor spatial coverage. We address these challenges in a unified framework.

Simplified SPAL technique to provide adequate peri‐implant phenotype: A pilot study

Clinical Advances in Periodontics, EarlyView.
Abstract Background Correction of peri‐implant bone dehiscence (PIBD) and optimization of the peri‐implant soft‐tissue phenotype are critical for long‐term peri‐implant tissues stability. A simplified, one‐stage, transmucosal variant of the subperiosteal peri‐implant augmented layer (sSPAL) technique was appraised and evaluated.

Critical expansion points: Mechanical signs of surrounding rock instability

Deep Underground Science and Engineering, EarlyView.
This study proposes the Rock Bearing‐Expansion Model (RockBEM) with critical expansion points (CEPs) to quantify post‐peak damage stages in deep‐buried rock masses via plane strain compression test (PSCT). CEP hysteresis&interval ratios reveal bearing performance dynamics and failure severity, advancing mechanistic insights into deep underground rock ...

Stereotactic Body Radiotherapy (SBRT) of Previously Unirradiated Mucosal Head and Neck Squamous Cell Carcinoma (SCC)

Head &Neck, EarlyView.
ABSTRACT Purpose To evaluate the efficacy and safety of stereotactic body radiation therapy (SBRT) in previously untreated primary mucosal head and neck cancer (HNC) patients unfit for conventional radiation therapy. Materials and Methods Retrospective analysis of previously unirradiated primary SCC mucosal HNC patients treated with SBRT from 2011 to ...

Hypervision Proton Surgery: The Future Direction of Proton Therapy

iNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

Augmented Reality of Anatomical Structures of the Maxillomandibular Complex for Learning Dental Radiographic Techniques

Journal of Dental Education, EarlyView.
ABSTRACT Introduction Augmented reality (AR) enables interactive learning in real‐world environments. In dental radiography education, AR offers a promising tool to enhance students' clinical skills by allowing them to simulate and practice procedures before engaging with actual patients. Repeated practice in an AR environment can reinforce theoretical

C-shaped Canal System in the Mandibular Second Molars in a Saudi Arabian Subpopulation Analyzed Using Cone-Beam Computed Tomography

Journal of Pharmacy and Bioallied Sciences
Background: The superimposition in radiographic images makes it difficult to diagnose C-shaped canals using two-dimensional imaging techniques. A non-invasive technique called cone-beam computed tomography (CBCT) makes it easier to comprehend the C ...
