Characterization and Crystallographic Evaluation of Wrought Stainless Steel Used As Wrougt Framework in Acrylic Partial Denture - An In Vitro Study
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 2
Abstract
One of the treatment option for Partially edentulous condition is by removable partial denture . The treatment option of partially edentulous condition is casts partial denture (CPD) & acrylic partial denture which is known as transient partial denture (TPD) widely. The designing concept of CPD is justified biologically & mechanically when compared to TPD. In our country TPD is widely used as definitive prosthesis because it is economical when compared to the CPD . Hybrid partial denture where in which wrought bars made of stainless steel were used to connect the right and left half of the arch , as a result the acrylic coverage is reduced well .A case series of partial denture rehabilated with wrought frame is presented here . An observational study was conducted with the aim of analyzing the metallurgy of stainless steel. The component present in the wrought frame work was analyzed using plasma emission spectroscopy . The main alloying element being Chromium 13 % .Wrought frame work when subjected to cold working the crystal structure will be altered resulting in catastrophic failure of the metal. Annealing was done to relive the stress and to get the lattice in arranged manner. The changes in the frame work before and after annealing was analyzed using optical microscope .The result of annealing is well appreciated by the ordered arrangement of the crystals.
