PURPOSE: The aim of this study was to evaluate volumetric and clinical outcomes of atrophic posterior mandibles treated with inlay or onlay bone grafting techniques. MATERIALS AND METHODS: In posterior mandibles, alveolar ridges were treated either with interpositional equine cancellous bone block (inlay group) or with onlay autogenous bone block (onlay group). Bone volumes at baseline and at 4 months after surgery were measured by computed tomography. RESULTS: A total of 20 subjects were enrolled in the present study: 10 in the inlay group and 10 in the onlay group...

BACKGROUND: In large incisional hernias and after laparostoma midline closure may be impossible. A novel abdominal wall expander system (AWEX) is proposed and evaluated. METHODS: In patients with large incisional hernias and laparostoma where primary midline closure was impossible, AWEX was used. Patients undergoing abdominal wall reconstruction using AWEX between May 2012 and December 2015 were included. Intraoperative the abdominal wall was stretched by attaching the midline fascia borders to a retraction system under tension for 30 minutes...

BACKGROUND: Piezo-surgery represents a novel alternative technique. The Piezo-surgery is well tolerated and permits a large number of applications in decribed literature. The principle of piezo-surgery consists into inducing micro-vibrations to a metallic insert with a particular custom. The aim of this article is to study and to evaluate the use of Nobelactive implants in combination with piezosurgical split-crest technique in severe atrophy of the upper maxilla. This approach allows avoiding the use of onlay grafts, due to rise the trasversal width of the crestal bone, which could have more complications and uncertain prognosis...

INTRODUCTION: Multidisciplinary burns care is constantly evolving to improve outcomes given the numerous modalities available. We examine the use of Biobrane, micrografting, early renal replacement therapy and a strict target time of surgery within 24h of burns on improving outcomes of length of stay, duration of surgery, mean number of surgeries and number of positive tissue cultures in a tertiary burns centre. METHODS: A post-implementation prospective cohort of inpatient burns patients from 2014 to 2015 (n=137) was compared against a similar pre-implementation cohort from 2013 to 2014 (n=93) using REDCAP, an electronic database...

INTRODUCTION: Cavity preparations of posterior teeth have been frequently associated with decreased fracture strength of the teeth. Choosing the correct indirect restoration and the cavity design when restoring the posterior teeth i.e., premolars was difficult as it involves aesthetic, biomechanical and anatomical considerations. AIM: To evaluate the fracture resistance and failure pattern of three different cavity designs restored with monolithic zirconia. MATERIALS AND METHODS: Human maxillary premolars atraumatically extracted for orthodontic reasons were chosen...

The aim of this article is to identify the indications for adhesively cemented restorations and to provide a correct step-by-step protocol for clinicians. New cavity preparation principles are based on morphological considerations in terms of geometry (maximum profile line and inclination of cusp lines), and structure (dentin concavity and enamel convexity). In this article, we discuss previous preparation concepts that were not designed purely for adhesive restorations and were therefore not conservative enough or suitable for adhesive procedures...

BACKGROUND: Incisional hernia is a frequent long-term complication after abdominal surgery, with a prevalence greater than 30% in high-risk groups. The aim of the PRIMA trial was to evaluate the effectiveness of mesh reinforcement in high-risk patients, to prevent incisional hernia. METHODS: We did a multicentre, double-blind, randomised controlled trial at 11 hospitals in Austria, Germany, and the Netherlands. We included patients aged 18 years or older who were undergoing elective midline laparotomy and had either an abdominal aortic aneurysm or a body-mass index (BMI) of 27 kg/m(2) or higher...

Revision rhinoplasties and saddle nose deformities usually require grafting for reconstruction. Between January 1, 2000, and January 1, 2017, autologous rib grafts were used in 127 secondary and tertiary rhinoplasty patients [(57/127 females) and (70/127 males)]. Osseous-cartilaginous rib grafts (OCRGs) were divided into three parts (i.e., 1/3 upper peripheral, 1/3 central, and 1/3 lower peripheral). The harvested OCRGs were also shaped as vertical strips using a number 11 scalpel blade. These OCRGs were shaped to form the L-strut cartilaginous graft (LSCGs), osseous-cartilaginous spreader grafts (OCSGs), osseous-cartilaginous onlay grafts, nasal valve grafts (NVGs), and lower lateral cartilaginous grafts (LLCGs)...

A novel and custom-made selective laser melting (SLM) 3D-printed alloplastic temporomandibular joint (TMJ) prosthesis is proposed. The titanium-6aluminium-4vanadium (Ti-6Al-4V) condyle component and ultra-high molecular weight polyethylene (UHMWPE) fossa component comprised the total alloplastic TMJ replacement prosthesis. For the condyle component, an optimized tetrahedral open-porous scaffold with combined connection structures, i.e. an inlay rod and an onlay plate, between the prosthesis and remaining mandible was designed...

REVIEW
Akio Horiguchi
Male anterior urethral stricture is scarring of the subepithelial tissue of the corpus spongiosum that constricts the urethral lumen, decreasing the urinary stream. Its surgical management is a challenging problem, and has changed dramatically in the past several decades. Open surgical repair using grafts or flaps, called substitution urethroplasty, has become the gold standard procedure for anterior urethral strictures that are not amenable to excision and primary anastomosis. Oral mucosa harvested from the inner cheek (buccal mucosa) is an ideal material, and is most commonly used for substitution urethroplasty, and lingual mucosa harvested from the underside of the tongue has recently emerged as an alternative material with equivalent outcome...

BACKGROUND: Reconstruction of the nasal lining is the most difficult part of complex nasal reconstruction because the mucosa has a unique texture and fineness. Many techniques, ranging from skin grafts to local flaps, have been applied for the reconstruction of the mucosa. In some cases, even free flaps have been used. OBJECTIVE: The aim of this study was to discuss the feasibility of using turn-in flaps in nasal reconstruction. MATERIALS AND METHODS: Seventeen patients with full-thickness nasal defects underwent reconstruction with turn-in flaps...

OBJECTIVE: To assess the role of registries in the postmarketing surveillance of surgical meshes. BACKGROUND: To date, surgical meshes are classified as group II medical devices. Class II devices do not require premarket clearance by clinical studies. Ethicon initiated a voluntary market withdrawal of Physiomesh for laparoscopic use after an analysis of unpublished data from the 2 large independent hernia registries-Herniamed German Registry and Danish Hernia Database...

Patellofemoral arthroplasty (PFA) has long been a clinical option for patients with isolated patellofemoral arthritis. However, a high rate of failure as a result of patellar instability related to component malposition, soft-tissue imbalance, errant surgical techniques, and poor trochlear implant designs contributed to the underutilization of PFA. The evolution of surgical indications, trochlear implant design, component positioning, and soft-tissue balance has led to improved patellar tracking, fewer failures related to patellar instability, and improved functional outcomes...

André V Ritter, Newton Fahl, Marcos Vargas, Rodrigo R Maia
In the direct-indirect composite technique, composite is applied to a nonretentive tooth preparation (eg, a noncarious cervical lesion or a veneer/inlay/onlay preparation) without any bonding agent, sculpted to a primary anatomic form, and light-cured. The partially polymerized restoration is then removed from the preparation and finished and tempered extraorally chairside. The finished inlay is bonded to the preparation using a resin-based luting agent. Advantages of this technique include enhanced physical and mechanical properties afforded by the extraoral chairside tempering process because of increased monomer conversion, and greater operator control over the final marginal adaptation, surface finishing and polishing, and anatomy of the restoration, given that these elements are defined outside of the patient's mouth...

Conventional dental implants have been reported for nasal and orbital regions but due to limited thickness of calvarium they are not used in mastoid region. Onlay bone grafting in skull concomitant with implants is a predictable method and experimental animal studies confirm it. Parietal bone and lateral mandibular ramus are suggested source of bone grafts and dental implants with 7 mm length can be used safely. Increased fixture length may lead to increase survival in long term.

BACKGROUND: Irregularities or deformities of the nasal dorsum after hump reduction account for a significant number of revision rhinoplasties. We therefore developed a technique of meticulously dicing and exactly placing free diced cartilage grafts (fDC), harvested from septum, rib, or ear cartilage. The cartilage paste is used for smoothening, augmentation, or camouflaging of the nasal dorsum in primary or revision rhinoplasties. METHODS: A retrospective analysis of multi-surgeon consecutive open approach rhinoplasties from January to December 2014 was conducted at a single center...

BACKGROUND AND AIM: In the age of synthetic prostheses most of hernia studies include a careful examination of the various types of prosthesis, their characteristics and their repair indications. Biological prostheses are also beginning to draw attention. But in terms of recurrence especially for poor or developing countries, the discussion is different, due to their high cost which makes them difficult to afford. In this article we present new flap reconstruction techniques for the reconstruction of the abdominal wall versus mesh repair, applied on swine models, outline the results of each technique, and specify the indications for their use...
