A novel technique of custom ocular prosthesis fabrication

The literature provides several techniques for fabricating ocular prostheses, ranging from stock to custom-made prostheses. A cosmetically acceptable ocular prosthesis is that which reproduces the colour, form and orientation of the iris and allows the patient to return to a ifestyle to which they were previously accustomed. A sequence of steps for construction of custom-made ocular prostheses is outlined in this case report with emphasis on accurate positioning of iris using a transparent graph template. Ocular rehabilitation restores the compromised aesthetics, maintains the normal physiology of the ocular area, and increases the social life and self-esteem of the patient.

Comparison of Two Techniques of Rehabilitating Ocular Defect with Custom Made Ocular Prosthesis

Ocular prostheses have a long history of successful use, and variations in the techniques and materials used have been introduced through the years. Advantages such as reduced treatment time and increased simplicity make this method a good alternative to conventional tedious methods of fabricating ocular prostheses. This case report outlines a sequence of steps for construction of cost effective custom made ocular prostheses by a simple method.

Prosthetic Rehabilitation of Ocular Defect Using Digital Photography: A Case Report

The fundamental objective in restoring a congenital as well as acquired defect of eye with an ocular prosthesis is to enable the patient to cope better with the difficult process of rehabilitation after an enucleation or evisceration. A cosmetically acceptable prosthesis is that reproduces the color, form and orientation of iris and allows the patient to return to accustomed lifestyle. A sequence of steps for construction of custom-made ocular prostheses is outlined in this case report using the advantages of digital imaging technique.

Automatic Reasoning for Design under Geometrical Constraints

Parametric design is very stable but requires a predefined dimensioning and ordering scheme, thus limiting flexibility and precluding sketch input. Variational geometry design, while general and flexible, necessitates intensive use of numerical solvers to solve many simultaneous nonlinear equations. Frequently the solvers cannot solve these equations. A new system, based on an original theory for automatic constraint analysis, has been developed for solving sets of two-dimensional geometric constraints in product design. The proposed system offers the flexibility of variational based design along with the stability of parametric design. The solution strategy is based upon breaking down the problem into a sequence of construction steps. When no sequential construction is found, auxiliary geometrical constructions are automatically generated based on rules for relocating constraints. Thus, an apparently simultaneous constraint set is converted into a set that can be constructed sequentially by decomposing strongly connected components of the original constraint graph. This new approach has been implemented in a system for designing sheet metal parts.

Fabrication of interim acrylic resin removable partial dentures with clasps

An orderly sequence of steps for construction of an interim acrylic resin partial denture has been presented. The technique allows the dentist to fabricate an effective restoration that has a definite path of insertion and removal that can be placed in the patient's mouth with little time spent on adjustment and correction. This technique may be used with heat- or cold-curing acrylic resin.
