Fabrication of a Biocompatible Nanoantimicrobial Suture for Rapid Wound Healing after Surgery.

Suture-associated infections on surgical sites are known to be related to the surface characteristics of the sutures. The present study aimed to fabricate a novel functional suture for surgical procedures and characterize its antioxidative, antimicrobial, and in vitro wound healing properties. St John's wort, , extract (eHp), and biogenic silver nanoparticles (AgNPs) have been combined and used for coating the silk sutures.

A 3D dynamic finite element analysis of biomechanical behaviour of maxilla and fixative appliances following advancement Le Fort I surgery applied in different lengths.

Objectives: Dynamic analysis of chewing impact on the stability of rigid fixation techniques following Le Fort I osteotomy has not been investigated in the previous literature. The aim of the present study was to evaluate segmental displacement and von Mises (VM) stress values on the fixation devices following different amounts of Le Fort I advancements under dynamic loading conditions.

Materials And Methods: The 3D finite element models simulating 3, 5 and 8 mm advancement of maxilla at the Le Fort I level were generated using CBCT scan data.

How do implant threads and diameters affect the all-on-four success? A 3D finite element analysis study.

Background: The effect of different thread designs and diameters on the all-on-four concept is unclear.

Objective: The aim of the study was to clarify the differences in stress distribution of dental implants with various thread designs and diameters based on the all-on-four concept with three dimensional (3D) finite element analysis (FEA).

Methods: A 3D model of a totally edentulous mandible was used to perform the FEA.

An Effective Phytoconstituent Aconitine: A Realistic Approach for the Treatment of Trigeminal Neuralgia.

Trigeminal neuralgia pain remains a challenge to treat. Natural compounds may be promising options for relieving pain. This study was aimed at investigating the effects of aconitine in a rat model of trigeminal neuralgia pain.

Does the angulation of the mandibular third molar influence the fragility of the mandibular angle after trauma to the mandibular body? A three-dimensional finite-element study.

The relationship between mandibular third molar (M3) angulation and mandibular angle fragility is not well established. The aim of this study was to evaluate the impact of M3 angulation on the mandibular angle fragility when submitted to a trauma to the mandibular body region. A three-dimensional (3D) mandibular model without M3 (Model 0) was obtained by means of finite-element analysis (FEA).

Coronal Split Corpus Osteotomy of the Mandible: A Modified Visor Osteotomy Technique for Bone Volume Enhancement.

The bony augmentation of severely atrophied mandible is generally required for the purposes of prosthetic rehabilitations. The treatment strategies have been well defined in the literature ranging from osteotomy techniques to distraction osteogenesis. Visor osteotomy is the milestone of the reconstructive surgery for the atrophied mandible which has received some modifications.

Biomechanical Evaluation of Different Fixation Methods for Mandibular Anterior Segmental Osteotomy Using Finite Element Analysis, Part Two: Superior Repositioning Surgery With Bone Allograft.

In this study, the biomechanical behavior of different fixation methods used to fix the mandibular anterior segment following various amounts of superior repositioning was evaluated by using Finite Element Analysis (FEA). The three-dimensional finite element models representing 3 and 5 mm superior repositioning were generated. The gap in between segments was assumed to be filled by block bone allograft and resignated to be in perfect contact with the mandible and segmented bone.

Biomechanical Evaluation of Different Fixation Methods for Mandibular Anterior Segmental Osteotomy Using Finite Element Analysis, Part One: Superior Repositioning Surgery.

The aim of the current study was to comparatively evaluate the mechanical behavior of 3 different fixation methods following various amounts of superior repositioning of mandibular anterior segment. In this study, 3 different rigid fixation configurations comprising double right L, double left L, or double I miniplates with monocortical screws were compared under vertical, horizontal, and oblique load conditions by means of finite element analysis. A three-dimensional finite element model of a fully dentate mandible was generated.

Hounsfield unit comparison of grafted versus non-grafted extraction sockets.

Volumetric changes of the alveolar ridge after socket preservation with various techniques have been investigated frequently. However, changes in bone density and quality of bone within the extraction sockets have seldom been studied. The purpose of this study was to evaluate the bone quality of grafted versus non-grafted socket sites prior to dental implant placement using Hounsfield unit (HU) values derived from cone-beam computed tomography (CBCT) imaging.

J-bone graft for the reconstruction of the jaws.

The J-bone graft technique has been used for the reconstruction of glenoid surfaces with significant bone loss in orthopedic surgery in which the J-shaped bicortical bone graft is harvested from the iliac crest. Because of the osteotomy design, the press-fit fixation into the defect is obtained. In this technical note, the authors adopted this technique to oral and maxillofacial surgery and described the technique for the reconstruction of the jaws.

Evaluation of bone graft harvesting techniques from anterior ilium.

Autogenous bone harvest from the anterior ilium is a common procedure in the surgical field. In the current study, a retrospective analysis was performed regarding the bone graft harvesting techniques from the anterior ilium. The retrospective analysis with a 1-year period included 16 patients who had undergone iliac bone grafting for oral and maxillofacial reconstruction.

Dental treatment of a patient with central sleep apnea and phobic anxiety under sedation: report of a case and clinical considerations.

Central sleep apnea (CSA) results from a reduction in lack of output from the central respiratory generator in the brainstem, manifesting as apneas and hypopneas without discernible efforts. CSA can lead to hypercarbia, arrhythmias, pulmonary hypertension, and heart failure. Indeed, the patient may develop a disturbed breathing during sedation procedures.

Unusually severe limitation of the jaw attributable to fibrodysplasia ossificans progressiva: a case report with cone-beam computed tomography findings.

Fibrodysplasia ossificans progressiva (FOP) is a rare hereditary connective tissue disease characterized by the progressive ectopic ossification of ligaments, tendons, and facial and skeletal muscles throughout life. Symptoms begin in childhood as localized soft tissue swellings. Immobility and articular dysfunction appear with involvement of the spine and proximal extremities.
