The implementation of augmented reality (AR) in image-guided surgery (IGS) can improve surgical interventions by presenting the image data directly on patient at correct position and actual orientation. This approach resolve switching focus problem, which occurs conventional IGS systems when surgeon has to look away from operation field consult a 2-dimensional screen. Microsoft HoloLens, head-mounted AR display, was combined with an optical navigation system create AR-based system....

The purpose of the study is to determine clinically relevant accuracy implant placement in edentulous maxilla using computer planning and a mucosa-supported surgical template.In each total 30 consecutive patients suffering from retention problems their upper denture, two or four Brånemark MkIII Groovy (Nobel Biocare®, Zürich, Switzerland) implants were installed. Preoperatively, first, cone-beam tomography (cone beam tomography) scan was acquired, followed by virtual planning. Hereafter,...

The purpose of this study was to determine the clinically relevant accuracy implant placement in augmented maxilla using computer planning and a mucosa-supported surgical template.Twenty-five consecutive edentulous patients with an extreme maxillar alveolar ridge resorption were treated bone augmentation procedure. In second stage, six Brånemark MkIII Groovy (Nobel Biocare®, Zürich, Switzerland) implants installed. Preoperatively, cone beam tomography (CBCT) scan acquired, followed by...

Background We described safety and functional one-year follow-up outcomes of individuals with lower limb amputation treated bone-anchored prostheses using titanium press-fit osseointegration implants. Methods All consecutive between March 2015 June 2018 curved femur implant (OFI-C) indicated for a long femoral remnant, gamma (OFI-Y) short or tibia (OTI) were eligible this study. adverse events evaluated, infections graded as follows: grade 1 2: low- high-grade soft tissue infection,...

To design a relevant method to compare the virtual planned implant position ultimately achieved and evaluate, in case of discrepancy, cause for this.Five consecutive edentulous patients with retention problems upper denture received four implants maxilla. Preoperatively, first cone-beam CT (CBCT) scan was acquired, followed by planning. Then, surgical template designed endosseous were flapless installed using as guide. inventory any differences position, postoperative CBCT matched...

Measurement and production of traditional prosthetic sockets are time-consuming, labor-intensive, highly dependent on the personnel involved. An alternative way to make prostheses is using computer-aided design (CAD) manufacturing (CAM). Fused Filament Fabrication (FFF) may be an low-cost sockets. This study investigates tensile properties potential printing materials suitable for FFF according ISO527 (Standard Test Method Tensile Properties Plastics). To ensure that FFF-printed safe patient...

The results of the self-expandable urethral stent (Wallstent) in treatment strictures were evaluated 7 patients with a followup 23 to 31 months. 4 failures caused by exuberant fibrotic proliferation lumen stent, which required further endoscopic 2 and even surgical removal 1. In other was progressive will require treatment. 1 patient there is slowly diminishing urine flow rate, seems be stable. Early reports on suggest that its use obviate necessity for complex surgery stricture. Strictures...

Flapless immediate implant placement and provisionalization (FIIPP) in the aesthetic zone is still controversial. Especially, an initial buccal crest thickness (BCT) of ≤1 mm thought to be disruptive for final stability jeopardizing outcome.To radiographically assess BCT height (BCH) after 1 year calculate correlation between achieved BCT.The study was designed as a prospective on FIIPP. Only patients were included whom one maxillary incisor considered lost. In six centers, 100 consecutive...

Not long after the introduction of osseointegrated implants outside oral cavity, auricular prostheses are retrained on implants. New insights have been gained with next-generation percutaneous titanium for bone conduction hearing since its in 2010. As a result, same technology was introduced Vistafix® system (VXI implant) to retain prostheses. The aim this study is evaluate surgical procedure, clinical outcome, and satisfaction patient osseointegration-retained prosthesis using VXI 11...

Currently, assessment of acetabular fracture reduction is mainly performed by evaluating 2D slices 3D CT scans. This subjective method can potentially be improved using models and objective analysis tools. In order to evaluate the potential value digital reconstructed in reduction, reconstructions fractured acetabulum were compared mirrored healthy contralateral side for both pre-, post-surgical setting.Thirteen patients with one-sided fractures included study. All received a postoperative...

Abstract Introduction Implant‐supported removable complete overdentures (IODs) are a common treatment in case of edentulism and malfunctioning the conventional denture. Manufacturing IODs way (C‐IODs) is time‐consuming, but digital workflow, this can be done three sessions. Digitally produced (3D‐IODs) also more advantageous than C‐IODs because lost or broken 3D‐IODs swiftly reproduced as design always available. Purpose To prove non‐inferiority study, with margin 0.3 point per Oral Health...

To assess the reliability and accuracy of linear measurements on three-dimensional (3D) cross-sectional images, both acquired with cone beam computed tomography (CBCT) multi-detector row CT (MDCT). Bone thickness was evaluated regard to image-guided planning craniofacial implant surgery.Five dry human skulls were used. Cuts made a circular bone saw at ideal positions in nasal, orbital, temporal regions prior acquisition CBCT MDCT scans. After imaging examination, width assessed by three...

The aim of this study was to evaluate a novel soft tissue-based method register an intraoral scan (IOS) with cone beam computed tomography (CBCT) scan. IOS and CBCT data were obtained from eight dentate patients (mean age 21±2 years; three male, five female) 14 fully edentulous 56±9 six female). An algorithm developed create tissue model the scan, which allowed registration be performed IOS. First, validation on jaws palatal mucosal surface accuracy evaluation at level teeth. Second,...

Purpose Fused filament fabrication (FFF) using tough poly lactic acid (PLA) was determined to be the most suited method achieve low-cost prosthetic sockets. However, improvement in material properties is desirable strengthen these This study aims evaluate annealing as a potential improve by heat treatment of object after 3D printing. Design/methodology/approach Four different methods and control group were tested according ISO standard 527–1 527–2. The four included: oven; sand; water;...
