Interdisciplinary approach for bilateral maxillary canine: First premolar transposition with complex problems in an adult patient

Abstract

Adult patients seeking orthodontic care were increased nowadays not only on esthetic need but also on functional demand. But problems with adult patients were not only malocclusions but also dental caries, pulpal pathology, missing teeth, muco-gingival problems and loss of supporting structures. We report here a case of 35-year-old female with complete transposition referred as a positional interchange of two permanent teeth within the same quadrant of the dental arch along with gingival recession of the lower anteriors and missing molars. Gingival health was improved by free gingival graft in lower anteriors followed by fixed orthodontic procedure to correct transposition. Based on transposition crown recontouring and restoration was done along with replacement of missing molars with fixed prosthesis. Thus, proper treatment planning with interdisciplinary management improves not only the esthetics and occlusal relationship but also with stable results.

Compositional Tailoring of Mg–2Zn–1Ca Alloy Using Manganese to Enhance Compression Response and In-Vitro Degradation

“…In the last decade, magnesium and its alloys have been extensively researched for potential applications in the field of orthopedics, craniofacial and cardiovascular applications [1][2][3][4][5][6]. Magnesium and its alloys have gained great attention as a biodegradable implant material because of its low density, high mechanical strength, Young's modulus (40)(41)(42)(43)(44)(45) matching close to the human bone (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20), and excellent biocompatibility [7][8][9]. These advantages of magnesium alloys have made them an exciting alternative in comparison to non-biodegradable metals like titanium alloys, cobalt-chromium alloys, and stainless steel for orthopedic and craniofacial applications [10][11][12].…”

The drawback of currently used bio-metals/alloys is the requirement of revision surgery to remove implants from the human body.…”

In vitro cytotoxicity and osteogenic potential of quaternary Mg-2Zn-1Ca/X-Mn alloys for craniofacial reconstruction

“…Bone loss caused by congenital defects, tumour resection irradiation, and trauma are common in craniofacial regions 1 . The bone loss occurring due to these conditions must be regenerated or replaced for the critical function of mastication, deglutition and most importantly to maintain the functional harmony and aesthetics of the facial complex 2 – 4 . Autografts have been a gold standard treatment options for bone loss 5 .…”

COVID-19 Biomedical Plastics Wastes—Challenges and Strategies for Curbing the Environmental Disaster

“…Garbage management systems throughout the world have, already, struggled to deal with current plastic waste, and the predicted rise in waste from the COVID-19 epidemic threatens to overload waste management systems as well as healthcare capacity. Medical waste from hospitals is particularly problematic, due to the need to destroy any residual pathogens [2,10].…”
