Simple and novel technique for fabrication of prosthetic vaginal dilators

Vaginal agenesis is one of the major congenital anomalies affecting women. Postoperative prosthetic vaginal dilators are indicated in patients treated surgically for vaginal agenesis. Although different dental materials such as acrylics and silicone-coated materials are used, addition silicones alone have never been used for the fabrication of prosthetic vaginal dilators. Addition silicone materials have advantages, such as high elastic recovery, high tear and tensile strengths, which aid in the definitive use of vaginal dilators. Vaginal dilators fabricated using addition silicone materials act as an efficient prosthesis in terms of function and ease of use in surgically treated vaginal agenesis patients.

Component Material

Posterior composite restorations are difficult to contour and polish due to their occlusal anatomy and opposing occlusion. Our study describes a technique for duplicating occlusal surface anatomy, using different dental materials that are able to copy anatomic details. The aim of the study was to evaluate the efficiency of occlusal matrix technique, by comparing technical ease of different dental materials. The study was conducted on extracted teeth which had intact occlusal surfaces or initial carious lesions at this level. An impression of the occlusal surface was made prior to cavity preparation, with four different dental materials: a flow composite, a dual-cure resin cement, a temporary acrylic resin (powder and liquid) and a temporary crown and bridge two-component material in a Unidose®. When the last layer of composite has been placed, the occlusal matrix was forced into the uncured composite to replicate the original occlusal surface, instead of performing manual curing and shaping as in the standard approach. Time needed for complete finishing the case, the hardness of each occlusal matrix and the final morphology obtained were evaluated. The main benefits of the occlusal matrix technique are the technical ease of use due to its simplicity and its high accuracy in reconstructing occlusal morphology. Although the shortest time needed for occlusal matrix preparation was for the dual-cure resin cement, the best oclusssal matrix was obtained with the temporary acrylic resin (powder and liquid).

Novel Method

Background and aim: Microtia is one of the forms of ear loss and deformity. A prosthesis that is simple to apply, and which has adequate suspension and acceptable aesthetics, can be useful in the rehabilitation of patients with this deficit and can improve the social and psychological effects of patients with ear amputation. The aim of this article was to describe a novel technique for fabricating ear prosthesis in a patient with congenital ear deformity. Technique: This method involves a novel method to produce an ear prosthesis using clips that were located within the layers of the final silicone ear. Discussion: This study demonstrated ease of use and acceptance by the patient. Design and fabrication of silicone ear prosthesis via this new method of suspension could also be suitable for provision to children with ear microtia who are not yet suitable for surgery or would not be suited to other methods of suspension. Clinical relevance The new method of suspension demonstrated that this approach could be used to provide low cost and acceptable silicone ear prosthesis for patients with microtia and partial ear amputation.

Better Than

In order to better understand the distribution of cell traction forces generated by rapidly locomoting cells, we have applied a mathematical analysis to our modified silicone rubber traction assay, based on the plane stress Green’s function of linear elasticity. To achieve this, we made crosslinked silicone rubber films into which we incorporated many more latex beads than previously possible (Figs. 1 and 6), using a modified airbrush. These films could be deformed by fish keratocytes, were virtually drift-free, and showed better than a 90% elastic recovery to micromanipulation (data not shown). Video images of cells locomoting on these films were recorded. From a pair of images representing the undisturbed and stressed states of the film, we recorded the cell’s outline and the associated displacements of bead centroids using Image-1 (Fig. 1). Next, using our own software, a mesh of quadrilaterals was plotted (Fig. 2) to represent the cell outline and to superimpose on the outline a traction density distribution. The net displacement of each bead in the film was calculated from centroid data and displayed with the mesh outline (Fig. 3).

Video Image Processing

The amphibian embryo offers advantages of size, availability, and ease of use with both microsurgical and molecular methods in the analysis of fundamental developmental and cell biological problems. However, conventional wisdom holds that the opacity of this embryo limits the use of methods in optical microscopy to resolve the cell motility underlying the major shape-generating processes in early development.These difficulties have been circumvented by refining and adapting several methods. First, methods of explanting and culturing tissues were developed that expose the deep, nonepithelial cells, as well as the superficial epithelial cells, to the view of the microscope. Second, low angle epi-illumination with video image processing and recording was used to follow patterns of cell movement in large populations of cells. Lastly, cells were labeled with vital, fluorescent dyes, and their behavior recorded, using low-light, fluorescence microscopy and image processing. Using these methods, the details of the cellular protrusive activity that drives the powerful convergence (narrowing)
