Transgender and gender diverse (TGD) individuals most often choose for phalloplasty as a means to create masculine external genitalia. The neophallus created in phalloplasty is usually insufficient for penetrative sexual intercourse due to the lack of erectile structures. Therefore, implantation of an internal erectile prosthesis or use of an external device or epithesis is required. Internal prostheses are the main method for attaining penile rigidity after phalloplasty, but they carry a high risk of complications. Previous research has shown that up to 22% of prostheses for cisgender men were explanted due to various reasons, including infection, erosion, and malfunction within 20 months. The lack of reliable and durable erectile devices leads to a large proportion of patients either choosing phalloplasty but never going for the placement of an erectile prosthesis or completely abandoning the idea of GGAS under the form of phalloplasty. Secondarily, TGD individuals may be concerned about complication rates and likely need for additional surgeries associated with penile implant surgery. Therefore, alternative options for transgender and gender non-conforming patients after phalloplasty are needed. These alternatives may be surgical or non-surgical. External penile epitheses or penile splints were originally designed for cisgender men with erectile dysfunction but have been used experimentally by post-phalloplasty transgender men. While there is no data on the usability and durability of penile epitheses in a TGD population, they may be a viable alternative to an internal penile prosthesis after phalloplasty. Penile lifters or splints, marketed as ElatorTM or ErektorTM, are commercially available and consist of two rigid rings connected by rigid metal rods. The biggest of two rings is placed around the base of the phallus, and the second ring is placed behind the coronal ridge. By connecting the rods to the ring at the base of the penis, tension and rigidity between the two rings is created, allowing the user to penetrate their partner and remove the device after intercourse. The current study aims to extend the knowledge on these external devices by comparing them to the implantation of an internal penile prosthesis in post-phalloplasty transgender patients.
The objective of our study is to evaluate the effectiveness of prone position in preventing intubation or death in spontaneously ventilated patients with COVID-19 with acute respiratory failure.
The aim of this study was to describe a novel digital technique to analyze the wear of screw-retained implant-supported metal-ceramic dental prostheses and natural tooth as antagonist. Materials and methods: Ten patients were consecutively included to rehabilitate partial edentulism by dental implants. Both the screw-retained implant-supported metal-ceramic dental prostheses and the natural tooth as antagonist were submitted to a digital impression through an intraoral scan to generate a Standard Tessellation Language digital file preoperatively (STL1), at 3 months (STL2), and 6 months (STL3) follow-up. Afterwards, an alignment procedure of the digital files (STL1-STL3) was performed on a reverse engineering morphometric software and volume changes at the screw-retained implant-supported metal-ceramic dental prostheses and the natural tooth as antagonist were analyzed using Student's t-test. Moreover, Gage R&R statistical analysis was conducted to analyze the repeatability and reproducibility of the digital technique.
This study titled "Prospective, Multicentre Study to Assess Performance of the MonoCer Acetabular Cup in Primary Total Hip Replacement" is a multi-centre prospective registry-nested cohort study, using AOANJRR's web-based data collection system integrated with Registry data collection, designed to assess the ten-year clinical outcome of the MonoCer Acetabular Cup in Primary Total Hip Replacement. The primary outcome measure is mortality and secondary measures are PROMs and complications.
The primary objective of the study is to evaluate the 10-year performance of the MPACT DM cup in the treatment of patients requiring total hip arthroplasty. The primary endpoint is the 10-year life span of the prosthesis according to the Kaplan Meier curve.
Sarcopenia and malnutrition are closely involved in frailty. To prevent them, it is essential to assess oral function. "Oral fragility" manifests with specific signs or symptoms, including occlusion loss due to tooth loss and chewing difficulty. To recover from it, restoring function by placing a dental prosthesis in the event of tooth loss is essential. In Chile, many patients referred to secondary care to perform new prosthetic treatment live in conditions of less oral functionality and enter waiting lists that can take years, impacting general functionality. Falls are a public health problem with a high economic cost, the second cause of death worldwide. One of the causes is sarcopenia, and it has been studied that the decrease in the number of teeth and the occlusal posterior support region may be risk factors for decreased gait speed, an objective measurement of fall risk. It has been studied that the decrease in the number of teeth causes a reduction in total muscle mass, walking speed and lower quality of life. General objective: To evaluate the impact on the general functionality of applying an immediate prosthetic functionalization protocol in patients with deficient removable prostheses, compared with conventional treatment, at the secondary level of the health system, in patients over 70 years of age. Methodology: randomized, double-blind clinical trial with two groups of 62 patients each: experimental and control. The intervention will consist of recovering prosthetic function in one session before conventional rehabilitation vs the control group receiving conventional rehabilitation. Measurements will include manual grip strength measurements made with a Jamar dynamometer, timed up-and-go test, before and after prosthetic treatments and quality of life related to oral health through Ohip 7sp. Descriptive statistics will be applied through the registration of frequency and contingency tables. To compare hand grip strength, Pearson's Correlation will be used; for risk of pre and post-fall, the t-test will be applied for two related samples; for quality of life before and after the intervention, Chi2 will be used; changes in grip strength, fall risk and quality of life, between the different groups according to the Eichner index, one-way ANOVA will be applied, for related samples.
The Intervention Will be All Ceramic Single-retainer Resin Bonded Fixed Partial Denture Using the Upper Canine as Abutment With Minimum Preparation on the Lingual Surface Within the Enamel Providing Maximum Area for the Retainer Bonding, to Replace the Upper Lateral Incisor and Will be Compared With the Control/Comparator Group Which is the All Ceramic Single-retainer RBFPD Using the Upper Central Incisor. The Participants in This Study Will be Recruited by the Researcher From the Clinic of Fixed Prosthodontics Department, Clinic of Orthodontics Department and Clinic of Diagnosis Department, Cairo University Without Any Financial or Non-financial Incentives.
This is a prospective observational clinical trial to evaluate the clinical performance of the Cerec Tessera prosthetic assembly on implants restored with chairside CAD/CAM-generated crowns. This investigation is intended as a Post Market Clinical Follow-up study for the product Cerec Tessera and its prosthetic assembly for implants, which will serve as a life-cycle approach to safety, backed up by clinical data and post-market monitoring.
The objectives of this study are to evaluate the performance and safety of the Vantage Mobile-Bearing Total Angle System. This study will follow subjects for a period of up to 10 years post-surgery.
