P. Ca Dathan, Kumar, T. Ma, Ravindran, Sa, Nair, KbChandrasek, and Kumar, A., “Prosthetic rehabilitation of lower limb with RTV siliconee using prosthodontic clinical and laboratory techniques – A case report”, Journal of Clinical and Diagnostic Research, vol. 10, pp. ZD35-ZD37, 2016.[Abstract]


variety of unique clinical and prosthetic challenges, because of distinctly different amputation levels of the lower limb. A female patient with history of Partial Foot Amputation (PFA) surgery at metatarsophalangeal joint level, due to crush injury reported for prosthetic rehabilitation. This case was successfully rehabilitated using room temperature vulcanizing (RTV) medical grade silicone for fabrication of foot prosthesis. Though limited in its function, it amply proves that the clinical and laboratory techniques used in fabrication of maxillofacial prosthesis can be effectively adapted for the fabrication of body prosthesis like toes and feet to enhance the quality of life of the patients. The patient was reviewed every year for three years. © 2016, Journal of Clinical and Diagnostic Research. All rights reserved. More »»

Bg, Jacob, Vg, and Anil, Sh, “Bioactivity and surface characteristics of titanium implants following various surface treatments: An in vitro study”, Journal of Oral Implantology, vol. 41, pp. e183-e188, 2015.[Abstract]


This study compared the surface topography, hydrophilicity, and bioactivity of titanium implants after 3 different surface treatments (sandblasting and acid etching, modified sandblasting and acid etching, and thermal oxidation) with those of machined implants. One hundred indigenously manufactured threaded titanium implants were subjected to 3 methods of surface treatment. The surface roughness of the nontreated (Group A) and treated samples (Groups B through D) was evaluated with a scanning electron microscope (SEM) and profilometer. The wettability was visually examined using a colored dye solution. The calcium ions attached to the implant surface after immersing in simulated body fluid (SBF) were assessed on days 1, 2, and 7 with an atomic electron spectroscope. The data were analyzed statistically. The SBF test allowed the precipitation of a calcium phosphate layer on all surface-treated samples, as evidenced in the SEM analysis. A significantly higher amount of calcium ions and increased wettability were achieved in the thermally oxidized samples. The mean roughness was significantly lower in Group A (0.85 ± 0.07) compared to Group B (1.35 ± 0.17), Group C (1.40 ± 0.14), and Group D (1.36 ± 0.18). The observations from this in vitro study indicated that surface treatment of titanium improved the bioactivity. Moreover, results identified the implants that were sandblasted, acid etched, and then oxidized attracted more calcium ions.

Microstomia has been defined as an abnormally small oral orifice associated with various etiopathologic factors. Management of these patients poses extreme difficulties in every procedure during prosthesis fabrication. Restricted mouth opening of the patient makes the insertion and the removal of the tray extremely difficult. So sectioning of the existing stock tray is necessary, so that the trays can be inserted and removed in sections. The main problem encountered during this procedure is the reorientation of the tray back in position. This article presents an innovative technique for the easy handling of the sectioned stock impression trays. © 2012 Indian Prosthodontic Society.
