A rare mental foramen variation and the role of cone‐beam computed tomography in preventing nerve injury: A case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background The interforaminal space is frequently used for dental implant placement due to its strategic location between the bilateral mental foramina. However, neurosensory disturbances following surgical intervention near the mental foramen (MF) can occur in up to 43% of cases.

A macrophage model of osseointegration

Current Directions in Biomedical Engineering, 2016
Abstract The mechanisms of peri-implant de novo bone formation and contact osteogenesis are still largely unknown. In 1984 Donath et al. showed that macrophages were the first cells to colonize a titanium implant. Recently it was shown that that there are inflammatory (M1) and healing macrophages (M2), the latter of which can secrete BMP

Quantifying Bite Forces for Solid Foods: Implications for Patients Postmandibular Reconstruction

Head &Neck, EarlyView.
ABSTRACT Background Bite forces required to masticate different food consistencies remain unknown, complicating dietary guidelines following mandibular reconstruction. This study quantifies the forces required for solid foods and estimates safe bite limits postreconstruction.

Assessing Implant Stability in Cementless Femoral Components With Different Interference Fits

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Cementless total knee arthroplasty implants offer advantages over cemented implants, such as bone preservation and easier revision procedures. However, the optimal interference fit required to achieve a good press‐fit fixation, essential for both primary and long‐term stability, remains uncertain.

Can Hounsfield Unit Evaluation of Preoperative CT Scans Predict Surgeon's Preference of Cementless Fixation in Total Knee Arthroplasty?

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Adequate bone quality is necessary for reliable cementless fixation during total knee arthroplasty (TKA). Hounsfield Units (HUs) can be a useful surrogate of bone density, and therefore a proxy of bone quality. We sought to determine whether HU would correlate with subjective intraoperative assessment of bone quality and hence use of ...

Osseointegration of Wrapped Dental Implants in Rabbits [PDF]

, 2015
Edentulous patients (those lacking teeth) require one of two approaches to augmentation: inserting a vertical bone graft, or subperiosteally anchoring a device on which an implant can be attached.

The Importance of Modeling Press‐Fit to Accurately Evaluate Interfacial Micromotion as an Indicator of Primary Stability in Uncemented Arthroplasty

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Arthroplasty is most often performed to alleviate pain and restore function in patients with end‐stage degenerative joint disease. Uncemented implant fixation is increasingly used in total knee and total ankle arthroplasty. Implantation using interference press‐fit is a manufacturer‐recommended guideline for achieving stable primary fixation ...

Pulsed electromagnetic field therapy on nonsurgical treatment of peri‐implantitis: 12–26 months follow‐up

Journal of Periodontology, EarlyView.
Abstract Background Pulsed electromagnetic field (PEMF) therapy, renowned for its immunomodulatory effects and established efficacy in orthopedics, shows promise for managing peri‐implantitis by reducing soft tissue inflammation and marginal bone loss.

Peri‐implant hypoxia as a potential barrier against ferroptotic mechanisms during peri‐implant diseases: A cross‐sectional study

Journal of Periodontology, EarlyView.
Abstract Background Hypoxia modulates inflammation and oxidative stress through hypoxia‐inducible factor‐1α (HIF‐1α). Ferroptosis, an iron‐dependent cell death process, is regulated by glutathione peroxidase‐4 (GPX4) and involves lipid peroxidation markers like malondialdehyde (MDA).

Titanium migration and bone response in loaded osseointegrated implants: ESEM‐EDX analysis in Macaca fascicularis

Journal of Periodontology, EarlyView.
Abstract Background Titanium nanoparticle (TP) migration into peri‐implant bone may influence osseointegration. It remains unclear how loading protocols may affect TP distribution. This study aimed to detect TP in the bone around implants undergoing different loading protocols in Macaca fascicularis.
