Abstract Background and objectives: For the planning of surgical procedures involving bony reconstruction mandible, autologous iliac crest graft, along with fibula has become established as a preferred donor region. While computer-assisted methods are increasingly gaining importance, necessary preparation geometric data based on CT imaging remains largely manual process. The aim this work was to develop test method for automated segmentation subsequent planning. Methods: A total 1,398...
Background and objectives: In oral maxillofacial operations, the iliac crest is a commonly used donor site from which to harvest bone for augmentation prior dental implantation or reconstruction of jaw defects caused by trauma pathological lesions. an aging society, proportion elderly patients undergoing grafting growing. Although postoperative morbidity usually moderate low, age health patient should be considered as risk factors complications delayed mobilization after operation. The aim...
Abstract Objectives In advanced stages of osteoradionecrosis, medication-related osteonecrosis the jaw, and osteomyelitis, a resection sections mandible may be unavoidable. The determination adequate bony margins is fundamental problem because cannot secured intraoperatively. Single-photon emission computed tomography (SPECT-CT) more accurate than conventional imaging techniques in detecting inflammatory jaw pathologies. clinical benefit for virtual planning mandibular primary reconstruction...
Introduction Up to one-fifth of breast cancer survivors will develop chronic cancer-related lymphoedema (BCRL). To date, complex physical decongestion therapy (CDT) is the gold standard treatment. However, it mainly symptomatic and often ineffective in preventing BCRL progression. Lymphovenous anastomosis (LVA) vascularised lymph node transfer (VLNT) are microsurgical techniques that aim restore lymphatic drainage. This international randomised trial aims evaluate advantages interventions...
Due to advancing digitalisation, it is of interest develop standardised and reproducible fully automated analysis methods cranial structures in order reduce the workload diagnosis treatment planning generate objectifiable data. The aim this study was train evaluate an algorithm based on deep learning for detection craniofacial landmarks cone-beam computed tomography (CBCT) terms accuracy, speed, reproducibility.A total 931 CBCTs were used algorithm. To test algorithm, 35 located manually by...
The morphometric analysis of maxillary sinus was recently presented as a helpful instrument for sex determination. aim the present study to examine volume and surface fully dentate, partial, complete edentulous depending on sex. Computed tomography data from 276 patients were imported in DICOM format via special virtual planning software, surfaces (mm2) volumes (mm3) sinuses measured. In sex-specific comparisons (women vs men), statistically significant differences mean found between dentate...
Aim: This in vitro study aimed to evaluate the effects of implant designs on primary stability different bone densities and bony defects. Methods: Five types (tapered-tissue-level, tissue-level, zirconia-tissue-level, bone-level, BLX implants) were used this assessment. The implants inserted into four artificial blocks representing varying bone-density groups: D1, D2, D3, D4. Aside from control group, three defects prepared. Using resonance frequency analysis torque-in -out values, each was...
Abstract Background This study aimed at comparing bracket placement and excess bonding adhesive depending on different indirect (IDB) techniques geometries. Methods Four hundred eighty brackets without hook (WOH) 360 with (WH) were placed 60 plaster models. Three IDB tested: polyvinyl-siloxane vacuum-form (PVS-VF), putty (PVS-putty), translucence double-polyvinyl-siloxane (double-PVS). PVS-VF PVS-putty combined chemically, double-PVS was light cured adhesive. Virtual images of models before...
Although nearly one-third of the world's disease burden requires surgical care, only a small proportion digital health applications are directly used in field. In coming decades, application augmented reality (AR) with new generation optical-see-through head-mounted displays (OST-HMDs) like HoloLens (Microsoft Corp) has potential to bring into However, for be performed on living person, proof performance must first provided due regulatory requirements. this regard, cadaver studies could...
Abstract Purpose For computer-aided planning of facial bony surgery, the creation high-resolution 3D-models bones by segmenting volume imaging data is a labor-intensive step, especially as metal dental inlays or implants cause severe artifacts that reduce quality computer-tomographic data. This study provides method to segment accurate, artifact-free 3D surface models mandibles from CT using convolutional neural networks. Methods The presented approach cascades two independently trained...
Abstract Background Orthognathic surgery can be carried out using isolated mandibular or maxillary movement and bimaxillary procedures. In cases of moderate skeletal malocclusion, camouflage treatment by premolar extraction is another option. All these surgical procedures have a different impact on the soft tissue profile. Methods The changes in profile 187 patients (Class II: 53, Class III: 134) were investigated. approaches differentiated as follows: mandible advancement (MnA), (MxS/MnA),...
The purpose of this pilot porcine cadaver study was to evaluate the feasible temperature thresholds, which affect osteocyte viability and bone matrix in a preclinical setup, assessing potential thermal necrosis for implant removal further vivo investigations.After bed preparation upper lower jaw, effects on were determined, using two tempering pistons with integrated thermocouples. To threshold time intervals leading necrosis, one piston generated warm temperatures at 49 56 °C 10 s other...
In this study is investigated if bundling of two scanners leads to better accuracy in recording faces than a standard face-scanning device.In group 28 volunteers, test specimens were attached their faces: one on forehead and turned 90° cheek. Each volunteer was scanned by FaceScan3D® bundled Artec EVA® scanners. The scans aligned three-dimensional model the specimen, mean error recorded. Length, width angles between specimen's planes compared.The deviation significantly lower for cheek...
