Introduction: Fracture of denture being most common clinical complain in daily Prosthodontic practice, results in great inconvenience to patient and humiliation to Prosthodontist. A satisfactory repair should be cost-effective, simple to perform, match the original color and not cause distortion to the existing denture. Objective: The aim of the present study is to investigate the effect of different surface treatments and surface design modifications on the transverse strength of repaired heat cure polymethylmethacrylate denture base resin Materials and Methods: A total of 135 rectangular specimens measuring 65 x 10 x 2.5 mm were made from heat cure PMMA resin using standardized mould. They were further divided into following 5 groups with 27 specimens in each group with simple random sampling method. Group A: control, Group B: 45° bevel of the edge, Group C: rounded contour of the edge, Group D: dichloromethane application at the edge and Group E: sandblasting of the edge. The repair index was fabricated with poly vinyl siloxane (putty). The specimens in each sample group were sectioned in the center to form 2 parts with approximately 3mm gap in between them. The sectioned surface of each sample group was modified according to their group specification and repaired using autopolymerizing acrylic resin. All the repaired specimens were tested for transverse strength in universal testing machine by subjecting them to 3-point bend test and the value at which the fracture of specimen occurred were noted. Data were analyzed with one-way ANOVA for multiple group comparisons followed by Tukey post hoc for group comparison (p<0.05). Results: Transverse strength of original specimen was higher than that of repaired specimen. Transverse strength of specimen repaired with surface design modification with rounded contour of the edge was higher than chemical and mechanical treatment and 45 bevel of the edge Conclusion: Within the limits of the study, irrespective of the method of repair, the transverse strength of surface design modification with rounded contour of the edges was significantly higher than the group repaired with surface design modification 45 bevel of the edge, chemical treatment with dichloromethane application at the edge and mechanical treatment by sandblasting of the edge.
Physical defects that compromise appearance or function, which prevent an individual from leading a normal life, usually prompt the individual to seek treatment that will reinstate acceptable normalcy. The loss of an eye impairs the patient’s visual function, yet also results in a noticeable deformity. Prosthesis should be provided as soon as possible to raise the spirits and ease the mind of the afflicted. An ocular prosthesis is a maxillofacial prosthesis that artificially replaces an eye missing as a result of trauma, surgery, or congenital absence. A custom ocular prosthesis has advantage of close adaptation to the tissue bed, provides maximum comfort and restores full physiological function to the accessory organs of the eye.
Importance and benefits of denture labeling have been widely described in forensic and dental community. It helps in identification and prevents the probability of losing dentures in geriatric edentulous patient. Several methods have been described in literature for the purpose of labeling denture. The article fully describes an inclusive method which is simple, economical, permanent and is done with equipment readily available in a laboratory.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
