“…10,11,13 The current design maintains the structural integrity of the catheter which can be lost in heat polymerization process of PMMA based mold. 8 It also avoids the use of dummy catheters which are occasionally used in heat polymerization of PMMA based molds, thus saving time and additional cost. 13 As compared to the 3D printed molds, the design execution of the current mold is economical and does not require any special equipment or manpower.…”

“…Several methods of fabrication of mold for brachytherapy have been documented. [7][8][9][10][11][12][13] PMMA based molds frequently carry wrought metal clasps which create disturbance in computer tomography (CT) scan during dosimetry. Gamma radiation has also been implicated to induce metal ion release and free radical formation with metal clasps.…”

Conservative management of metachronous second primary carcinoma of head and neck is preferred in order to preserve form and function. The purpose of the case report is to describe the treatment of metachronous second primary carcinoma of soft palate by high-dose-rate, remote, afterload brachytherapy. The brachytherapy was done in remote settings by afterloading Iridium 192 isotope carried through a custom fabricated surface mold. The mold enabled good adaptation, stability, and repeatable positioning of the radiation source at each treatment session of fractionated brachytherapy offering consistent dosimetric advantage through a single dosimetry calculation. Collaborative efforts of radiation oncologist and prosthodontist ensured conservative treatment in outpatient set up with minimal adverse effects.
