“…Deterioration is mainly caused by environmental exposure to ultraviolet (UV) light, air pollution, and changes in humidity and temperature. 3 Chemical disinfection can produce some property alterations of the silicones used as a maxillofacial prosthesis material, so it is important to evaluate these alterations during prosthesis fabrication. Sterilization of dental instruments, equipment and materials has long been suggested and accepted as a requirement in the dental care area.…”

Evaluation of hardness and surface roughness of two maxillofacial silicones following disinfection

2009

The purpose of this study was to evaluate the Shore A hardness and surface roughness of two silicones for maxillofacial prosthetic treatment, under the infl uence of chemical disinfection and storage. Twenty-eight specimens were obtained, half of which were made of Silastic MDX 4-4210 silicone and, the other half were made of Silastic 732 RTV silicone. The specimens were divided into four groups: Silastic 732 RTV and MDX 4-4210 with disinfection 3 times a week with Efferdent tablets and the same materials without disinfection. The hardness of the materials was analyzed with a Shore A Durometer. The surface roughness was established by a digital portable roughness tester, initially and 2 months after the confection of the specimens. A variance test was applied (2-way ANOVA), followed by Tukey test (the level of signifi cance was set at 1%). The storage time factor statistically infl uenced (p < 0.01) the materials' properties of hardness and roughness. MDX 4-4210 (28.59 Shore A, 0.789 Ra) presented higher values than Silastic 732 RTV (18.08 Shore A, 0.656 Ra) for both properties. Regarding the disinfection period, there was no signifi cant difference in any of the materials tested.

“…But silicone is the material of choice as it is flexible and easy to merge with adjacent tissues and provide natural like appearance as in this presented case [29]. But the limited service of maxillofacial prostheses is usually a consequence of deterioration of the elastomer and color change under environmental exposure to sunlight and change in temperature, humidity and hand contact during cleaning, and adhesive use on a daily basis (Chen et al [30], 1981, and Hanson et al [31], 1983)…”

“…Deterioration is mainly caused by environmental exposure to ultraviolet (UV) light, air pollution, and changes in humidity and temperature. Handling the prosthesis during cleaning and the application of adhesives and cosmetic additives may also alter the physical properties and color stability of the material [30, 31, 33, 34]. …”

Insufficient knowledge of medical chemicals and their improper use have destructive effects. Accidental exposure to chemicals on facial tissue may result in large facial defect. For ages the tradition of piercing nose is common but improper use of unknown chemical for piercing has deleterious effect. Mostly rhinectomy defects are acquired caused by trauma or malignant diseases. Prosthetic rehabilitation is the preferred treatment of choice for any large rhinectomy defects as medical and surgical interventions are ineffective in developing esthetics. Main concern with the prosthesis for such defects is retention. This article describes rehabilitation of a patient with large size nasal defect created by chemical burn in childhood during piercing. Implant retained customized silicone nasal prosthesis was fabricated using simple O-ring attachments and innovative modified polyamide acrylic resin substructure acting as skeleton.

“…Lewis and Castleberry4 stated that the ideal colour properties required in a maxillofacial prosthetic material must accept and retain intrinsic and extrinsic colouration, and that the appearance and mechanical strength of the prosthesis must not be changed by sunlight or other environmental factors. Colour instability of the prosthesis may be attributed to ultraviolet light exposure, air pollution, cosmetics and the use of strong solvents to clean the prosthesis 5 – 7…”

This is a clinical case report of a 52-year-old male patient with four partially missing fingers of the left hand. The article describes the clinical and laboratory procedure of making prosthesis with modern silicone material. A wax pattern was fabricated using the right hand of the patient. A special type of wax was formulated to make the pattern so that it can be easily moulded and carved. Intrinsic and extrinsic staining was also performed to match the adjacent skin colour. The patient was given the finger prosthesis and was asked to use a half glove (sports) to mask the junction between the prosthesis and the normal tissue. It also provides additional retention to the artificial fingers. The patient felt his social acceptance improved after wearing the finger prosthesis.
