Full-Mouth Implant-supported Rehabilitation with a Flapless Surgical Technique: A Treatment Approach
Successful implant treatment includes osseointegration as well as prosthetically optimal positions of the implants for esthetics and function. Computer-assisted oral implant surgery offers several advantages over the traditional approach. The purpose of this report was to evaluate a complex case of a 28-year-old female patient who lost all her teeth as a result of a aggressive periodontal disea...
This report describes a 3-dimensional (3-D) video-assisted thoracoscopic lung resection guided by a 3-D video navigation system having a patient-specific 3-D reconstructed pulmonary model obtained by preoperative simulation. A 78-year-old man was found to have a small solitary pulmonary nodule in the left upper lobe in chest computed tomography. By a virtual 3-D pulmonary model the tumor was fo...
Recognition of aberrant root canal configurations is critical to successfully negotiate and treat a one such aberrancies C shape system. The fins webs present in system presents challenge debridement obturation. Knowledge variations through advanced imaging modalities like CBCT, rotary hand instruments assisted with ultrasonics modified obturation techniques aid effective management shaped cana...
An 88-year-old right-handed man was admitted to our hospital for cognitive impairment and right-sided paralysis. His head non-contrast computed tomography (CT) showed large low-density areas (LDA) fibrous structures in the left occipital temporal lobe regions. Despite fact that it had been more than 10 years since his stroke, rehabilitation effective. This is a rare case which cerebellar culmen...
BACKGROUND Because of the increasing importance of computer-assisted post processing of image data in modern medical diagnostic we studied the value of an algorithm for assessment of single photon emission computed tomography/computed tomography (SPECT/CT)-data, which has been used for the first time for lymph node staging in penile cancer with non-palpable inguinal lymph nodes. In the guidelin...
OBJECTIVE To determine the predictive value of sentinel node biopsy (SNB)-assisted neck dissection in patients with oral squamous cell carcinoma (SCC) stage T1 to 2N0M0 and to determine the incidence of subclinical metastases. STUDY DESIGN Prospective cohort study. METHODS Fifty-one patients with clinically N0 neck underwent SNB-assisted neck dissection. The localization of the sentinel nod...
The rate of successful video-assisted thoracoscopic surgery (VATS) for resection of pulmonary nodules has improved since the development of radiologic localization techniques. The failure rate has decreased from 45% to 5%.1 Several techniques have been described, including methylene blue injection, hook-wire localization, and combined techniques, but none has proved entirely satisfactory.2-5 We...
PURPOSE Laparoscopy-assisted distal gastrectomy for early gastric cancer has gained acceptance and popularity worldwide. However, laparoscopy-assisted distal gastrectomy for advanced gastric cancer is still controversial. Therefore, we propose this prospective randomized controlled multi-center trial in order to evaluate the safety and feasibility of laparoscopy assisted D2-gastrectomy for adva...
Computed tomography colonoscopy (CTC) is an emerging alternative to conventional colonoscopy for colorectal cancer screening. A series of computer assisted diagnosis (CAD) techniques have been developed for use in CTC. Although high levels of accuracy for polyp detection have been reported, the problem of excessive false positive detections still warrants attention. We present a CAD-CTC techniq...
Optical coherence tomography (OCT) is an imaging technology with the potential to provide high-resolution images of the skin non-invasively. With this device, it is possible to identify a host of skin structures including tumors. In this case report, we demonstrate the use of an OCT device in delineating a lateral tumor margin of an ill-defined basal cell carcinoma prior to Mohs micrographic su...
