Auto-transplantation procedure, to replace lost tooth, where implant or fixed/ removable prosthetic option isn't recommended/ possible, as in child patients and young adults, have wide range of success rate. Not only proper case selection including transplantable tooth selection with ideal stages of root completion and root configuration, available bone and soft tissue; but also the surgical skill and post-surgical care play important roles for the success of the procedure. Here, 2 cases of auto-transplantation have been discussed.
Cartilage is avascular with limited to no regenerative capacity, so its loss could be a challenge for reconstructive surgery. Current treatment options for damaged cartilage are also limited. In this aspect there is a tremendous need to develop an ideal cartilage‐mimicking biomaterial that could repair maxillofacial defects. Considering this fact in this study we have prepared twelve silicone‐based materials (using Silicone 40, 60, and 80) reinforced with hydroxyapatite, tri‐calcium phosphate, and titanium dioxide which itself has proven their efficacy in several studies and able to complement the shortcomings of using silicones. Among the mechanical properties (Young’s modulus, tensile strength, percent elongation, and hardness), hardness of Silicone‐40 showed similarities with goat ear (P > .05). Silicone peaks have been detected in FTIR. Both AFM morphology and SEM images of the samples confirmed more roughed surfaces. All the materials were nonhemolytic in hemocompatibility tests, but among the twelve materials S2, S3, S5, and S6 showed the least hemolysis. For all tested bacterial strains, adherence was lower on each material than that grown on the plain industrial silicone material which was used as a positive control. S2, S3, S5, and S6 samples were selected as the best based on mechanical characterizations, surface characterizations, in vitro hemocompatibility tests and bacterial adherence activity. So, outcomes of this present study would be promising when developing ideal cartilage‐mimicking biocomposites and their emerging applications to treat maxillofacial defects due to cartilage damage.
Loss of facial structure as a consequence of injury or salvaging surgery, demands reconstruction and rehabilitation of lost structures. Here comes the role of a reconstructive and craniofacial surgeon. Lots of surgical options are available to fulfil the requirement but all require a second operative site to restore the primary defect. New age of scientific development are in search of regenerate the lost structures by the means of stem cell or biocompatible material. In such search we have tried to contribute by development of implant mimicking cartilage to reconstruct the lost facial structure. In this article we are going to share our research experience, to fulfil our goal and objective we have developed three different types of biocompatible silicon material (Si-40, Si60 & Si80). After formulation, preparation and mechanical characterization, it was observed that Si40 was best suitable silicone for bio-composite preparation.
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.
