Redefning precision in orbital prosthesis Rekha Gupta Maulana azad Insttute of Dental Sciences Introduction : orbital defects are seen as a culmination of management of tumors of orbital contents or as a result of immuno-compromised conditions . These defects lead to significant facial disfigurement, functional limitations, and negative psychological impact on the patient. Even though prosthetic rehabilitation of such defects is extremely challenging, it is extremely fulfilling when done right. Orbital prosthesis fabrication is an art in itself. Various techniques have been advocated to fabricate an orbital prosthesis, retained by a myriad of options such as adhesives, magnets or implants. With the advent of rapid prototyping, it has become possible to incorporate this technology in the improvisation of the conventional methods of fabrication. . Material and methods: a 50 yr old male patient reported in the opd with an orbital defect due to mucormycosis. The defect was rehabilitated with a silicone prosthesis which was a two-staged fabrication: first an inner mould was digitally fabricated , hollow in shape to reduce the weight, precise in fit owning to its exact dimensions as well as biocompatible due to its materials . The second stage involved making the silicone prosthesis attached to the inner mould.. Conclusion: a perfect synergism of the conventional design with a digital novelty resulted in a well-fitting, stable and aesthetic orbital prosthesis.. DOI: 10.4103/0972-4052.246596 23. Precision through digital technology: A case report Reshma Kulkarni Government Dental College, Bangalore A patient who has lost his appearance and identify because of some curse in life wants to live a dignified life for himself and for the society . As a prosthodontist we can sculpt his lost part of his face, but along with the digital technology we can make him appear more human. . A patient who had lost his eye because of mucormycosis has been reconstructed using the digital technology , 3d printing and with the knowledge of artist, making rehabilitation work much easier.

Clinical and radiographic evaluation of platform switched implants Rohan Bhoil 12 CDU / Army Dental Corps Purpose : to find effects of platform switch technique on dental implants in relation to crestal bone height changes, implant stability and probing depth, in the indian subpopulation.. Material & methods: 30 implants were divided into two equal groups - platform matched (group i) and platform switched (group ii). Variables were studied at time of placement and after six and twelve months of implant placement.. Results at end of study period, group i showed a mean mesial marginal bone loss of 1.4±0.4 mm, and 1.5±0.3mm on distal side. These values were1.0±0.2mm and 1.1 ±0.2 mm, respectively for group ii. Mean implant stability quotient was 66.9±3.7 for group i and 69.2±5.5 for group ii. Mean probing depth was 2.2±0.4mm for group i and 2.1±0.2mm for group ii.. Conclusion from these preliminary findings, it can be concluded that platform switch technique seems to limit crestal bone remodeling to a certain extent. This beneficial effect manifests after exposure of the implant to oral environment and may increase long term predictability of implant therapy vis- à-vis the platform matched implants. Hence, it would be desirable to incorporate such design features into implant design. However long term follow up is required to draw an effective conclusion regarding the implant stability and probing depth of the peri-implant soft tissues.. The results obtained with platform switch technique, on indian sub- population, is consistent with those obtained by other researchers on varying subject populations of different nationalities.. Keywords: platform switch, platform match, implant, crestal bone loss, implant stability. DOI: 10.4103/0972-4052.246598 25. Implant dentistry : From failure to success Sattyam Wankhade GDC, Nagpur Understanding failures and their causes is more difficult with implant supported prosthesis than with conventional prosthodontics perhaps because of the greater risk or invasiveness of the procedues and/or the greater expense to the patient. Most unsuccessful cases are the
