This paper presents a new technique for automatically detecting and diagnosing the repetitive surface defects in hot rolling. In the paper, surface image data of the hot rolled bars is online collected using advanced image sensors, and an automatic defect detection algorithm is developed for identifying the rollinduced repetitive surface defects by integrating the Canny detector and the Hough t...

Fig. 1. Computed tomography clearly demonstrated lung hernia of the right lower lobe through a chest wall defect at the site of a previous thoracoscopic surgery. At the previous thoracoscopic surgery, intercostal incision was closed with two interrupted sutures passing over the rib above the incision and through the rib below the incision, and three horizontal mattress interrupted sutures trave...

While AlGaN quantum cascade electro-optic devices recently received particular interest, the behavior of such vertical devices is not well understood and their performance greatly lags behind that of horizontal devices. The RTD is a benchmark for any such quantum cascade/intersubband (ISB) device. While epitaxial quality of InGaN/AlGaN could be improved so far that blue laser diodes became poss...

BACKGROUND Lower eyelid reconstruction after tumor removal is always challenging, and full-thickness defects beyond half of the eyelid length require a flap from a part other than the remaining lower eyelid, such as the temporal area or the cheek. OBJECTIVE We aimed to report our experience of applying Smith-modified Kuhnt-Szymanowski, one of the most popular procedures for paralytic ectropio...

BACKGROUND Localized alveolar ridge defect may create physiological and pathological problems. Developments in surgical techniques have made it simpler to change the configuration of a ridge to create a more aesthetic and more easily cleansable shape. The purpose of this study was to compare the efficacy of alveolar ridge augmentation using a subepithelial connective tissue graft in pouch and m...

Lateral ridge augmentation procedures are aimed to reconstruct deficient alveolar ridges or to build up peri-implant dehiscence and fenestrations. The objective of this systematic review was to assess the efficacy of these interventions by analyzing data from 40 clinical studies evaluating bone augmentation through either the staged or the simultaneous approach. The PRISMA (Preferred Reporting ...

We report the eventually successful treatment of a huge bone defect and peri-implantitis following reconstruction of a previously failed intra-mobile cylinder implant system (IMZ) implant site using distraction osteogenesis (DO). In the anterior mandible, two IMZ implants failed and surgical debridement was performed in accordance to the patient's needs. Thereafter, mobility and suppuration wer...

PURPOSE The purpose of this case series was to evaluate the effect of guided bone regeneration using demineralized allogenic bone matrix with calcium sulfate. MATERIALS AND METHODS Guided bone regeneration using Demineralized Allogenic Bone Matrix with Calcium Sulfate (AlloMatrix™, Wright. USA) was performed at the time of implant placement from February 2010 to April 2010. At the time of the...

We present the use of deproteinized bovine bone mineral and a non-crosslinked collagen membrane for reconstruction significant alveolar defect in this clinical case report,. The patient had extensive loss anterior maxillary region, posing challenge implant placement. Therefore, ridge preservation was performed following tooth extraction, resulting horizontal regeneration. Two implants were subs...

BACKGROUND The objective of this multicenter, randomized trial was to compare enamel matrix derivative (EMD; test) with barrier membranes (control) for the treatment of mandibular buccal Class II furcation defects. METHODS Forty-five patients with 90 comparable defects on contralateral molars were included. Defects were randomly assigned to EMD or bioabsorbable barrier membrane; the contralat...
