Changing ocular prostheses in growing children: a 5-year follow-up clinical report.

Eye loss in children can be caused by trauma, glaucoma, or cancer, and may result in anxiety and depression. Recovery after eye loss involves a replacement with a custom-made eye prosthesis, but, as the patient ages, changes in the size and shape of the eye socket can result in a sunken appearance of the child's prosthetic eye. This article describes the fabrication of a custom-made eye and the necessity of changing ocular prostheses for a growing child, with a 5-year follow-up.

Effect of Dietary Simulating Solvents on the Mechanical Properties of Provisional Restorative Materials-An In Vitro Study.

The purpose of this investigation was to evaluate the mechanical properties of provisional restorative materials after storage in dietary simulating solvents. A total of 120 specimens, 40 specimens each of Luxatemp Star, Revotek LC and DPI Self Cure were prepared. The specimens were divided into four groups with 10 specimens each and stored in dietary simulating solvents for 7 days at 37 °C as follows: Group I-Control, Group II-Artificial saliva, Group III-0.02 N Citric acid and Group IV-Heptane. After 7 days, flexural strength was obtained using universal testing machine at a crosshead speed of 5 mm/min and the fractured specimens were immediately subjected to the microhardness test knoop hardness number by using Knoop microhardness tester (10 gm/15 s). The data were analyzed for difference by use of Kruskal-Wallis and Dunn's multiple comparison tests using a significance level of 0.05 to determine the mean differences. Significant effect was observed on the properties of provisional restorative materials after storage in dietary simulating solvents as compared to the control group (p ≤ 0.05). Bis-acryl resin based Luxatemp Star showed significantly superior flexural strength and hardness as compared to the Revotek LC and DPI Self Cure in dietary simulating solvents. Within the limitations of this study, it may be concluded that dietary simulating solvents showed significant influence on the mechanical properties of the provisional restorative materials.

A modified technique for retention of orbital prosthesis.

An orbital defect (congenital or acquired) causes severe facial asymmetry and disfigurement, which results in psychological and social disturbances to the patient. It becomes a challenging task for a maxillofacial prosthodontist to fabricate a prosthesis that replicates the healthy side of the face. Success of the prosthesis depends primarily on satisfactory retention of the same. This clinical report illustrates rehabilitation of a patient with an orbital defect by fabricating a hollow orbital prosthesis, utilizing anatomical undercuts for retention using an acrylic resin template relined by a resilient denture liner.
