The Powder X-ray diffraction (PXRD) data of Nelumbo Nucifera fibre is utilized to study multifaceted properties. Rietveld refinement was carried out along with cellulose phase. The crystallite size was computed using the Scherrer equation, and through first principle calculations, it has been illustrated and concluded that the size is not ellipsoidal, as previously suggested by other researchers; rather, it exhibits a multidimensional shape.

Patients are placed in a crippling predicament due to the functional and psychosocial difficulties brought on by the illness and its treatments. Both surgeons and maxillofacial prosthodontists may encounter challenges with reconstruction and therapy following cancer treatment.

Comparative assessment of their mechanical properties will help the clinician select the right product for a specific clinical situation, but a systematic review is lacking.
Purpose: The purpose of this systematic review was to analyze the existing data in the literature regarding 5 mechanical properties of tissue adhesives for extraoral silicone prostheses: peel strength, tensile strength, shear strength, torsional strength, and tack.
Objective: Stable and accurate positioning of condyle in the glenoid fossa is necessary for maintaining occlusion, facial symmetry and normal function of the temporomandibular joint following segmental resection of mandible. In non-reconstructed mandibular segments or those with fractured reconstruction plates the bony defect gets altered due to contraction or inadvertent muscular pull. This paper describes various techniques used to control dentate and edentate segments of the mandible during reconstruction following an ablative procedure.

Three-dimensional reconstruction of these mandibular segmental defects is critical for proper mandibular functioning and esthetics. Various methods used to reconstruct such defects include bridging reconstruction plates, modular endoprosthesis, non-vascularized and vascularized bone grafting with stock reconstruction plate or patient specific implants (PSI) and tissue engineering bone transfer.
