PURPOSE To investigate the relationship between post and core build-up materials on the fracture resistance of endodontically treated teeth restored with different onlay restorations. METHODS 60 mandibular molars were endodontically treated and divided into three experimental groups that received one of the following onlay restorations: gold onlays, glass ceramic onlays (Empress I), or resin ...
OBJECTIVES To study the feasibility of urethral reconstruction with two urethroplasty techniques using an elastin and collagen heterograft in rabbits. MATERIALS AND METHODS Fifty-two male rabbits were studied. Two types of injury, (1) a 1.5 x 0.6 cm2 semicircumferential defect; (2) a 1.5 cm segmental defect of the penile urethra, were created and repaired using size-matched elastin and collag...
BACKGROUND A cartilage wedge block and covering flap are standard procedures for firm elevation of the ear in microtia correction. However, using costal cartilage for elevation of the reconstructed auricle can be insufficient, and the fixed cartilage wedge block may be absorbed or may slip out. Furthermore, elevating covering flaps is time-consuming and uses up fascia, a potential source of rec...
BACKGROUND Incisional hernia after abdominal surgery is a well-known complication. Controversy still exists with respect to the choice of hernia repair technique. The objective of this study was to evaluate the long-term recurrence rate as well as surgical complications in a consecutive group of patients undergoing open repair using an onlay mesh technique. METHODS Consecutive patients underg...
The objective of this study was to analyze the distribution of tensile stresses in indirect restorations prepared in several composite cavity bases. Elastic moduli of 20 materials were measured by nanoindentation technique for finite element analysis. Axisymmetric models of posterior onlays were constructed using combinations of two onlay materials and three cavity base materials. Thickness of ...
The aim of this study is to evaluate the efficacy of the application of allogenous bone at the maxillomandibular reconstructions for future rehabilitation with dental implants. The patients were submitted to reconstruction of maxilla, using allogeneic bone grafts, in 3 different techniques: onlay grafts for lateral ridge augmentation, onlay and particulate bone for sinus lift grafting, and part...
The management of patellae with a severe bony deficiency during revision total knee arthroplasty is a challenging problem. However, using a technique of augmentation with transcortical wiring of an onlay-type prosthesis allowed the authors to revise a deficient patellae successfully. After making the decision to revise the existing patellar component, the procedure was found to be technically s...
Surgical treatment of urethral strictures is a continually evolving process, and currently there is renewed controversy over the best means of urethral reconstruction. Buccal mucosa graft (BMG) has gained much interest because of its excellent short and long-term results, low post-operative complication rate, and relative ease of use [1,2]. A number of series reported success rate of 87-90% usi...
Controversy exists regarding the most predictable salvage for failed total ankle replacement. Revision total ankle replacement with soft-tissue release/reconstruction or explantation with tibio-talo-calcaneal arthrodesis with bulk structural allograft are the most commonly performed approaches. Tibio-talo-calcaneal arthrodesis with bulk structural allograft has a high complication rate; however...
UNLABELLED Although the literature has provided clinicians with some awareness of restorative material alternatives, such as laboratory-processed composite resin, these systems are not yet fully understood and implemented in daily practice, despite their benefits to dental patients. Whereas part I highlights treatment planning, preparation design, and impression making for an indirect resin onl...
