Customized reconstruction of an extensive mandibular defect: A clinical report

Abstract

Myoepithelial carcinomas are rare malignant tumors arising from salivary glands. They most commonly involve the parotid and minor salivary glands but may also occur in the submandibular glands. These tumors can become extensive, causing bony expansion and destruction. A 31-year-old man with a large swelling on the left side of the face is presented. Histologic examination of an incisional biopsy confirmed a diagnosis of a myoepithelial carcinoma arising from the left submandibular salivary gland. After tumor resection, the patient's mandible was reconstructed with a customized mandibular framework produced by means of 3-dimensional (3D) laser sintering. This approach significantly reduced cost, advanced surgical procedures, and operating room time, which is of great benefit in a developing country like South Africa.

Lower Susceptibility of Laser-irradiated Ti-15Mo Surface to Methicillin-resistant Staphylococcus aureus Cells Adhesion

“…Yet, titanium-6aluminium-4vanadium (Ti-6Al-4V) alloy is often the material of choice used to produce biomedical implant components [8][9][10][11] , prosthetic stems for total hip arthroplasties 12 , and prosthetic devices for mandible reconstructions 13,14 , due to its superior mechanical strength compared to commercially pure titanium (cpTi) 15 .…”

Prosthetic rehabilitation of a patient with hemimandibulectomy by a double occlusal table prosthesis

“…Mandibular deformity rehabilitation is of utmost importance to restore oral function. 15 The rehabilitation of mandibular defects are challenging because in addition to the loss of anatomical structures, there is a proprioceptive loss which leads to the absence of sensation of muscles of mastication and occlusion. 16 Hence, the purpose of this report was to present a prosthetic device that would help in acquiring the normal physiological oral functions.…”

From bench to bedside – current clinical and translational challenges in fibula free flap reconstruction

“…Upon this prototype, the definitive titanium osteosynthesis plate can be flexed, pressed, or molded preoperatively, and most notably, controlled against the stereolithographic model ( 98 ). For assisting in surgical planning and checking the fitting accuracy of the PSI preoperatively a polyamide 3D anatomic model of the remaining mandible can be fabricated by means of 3D printing (i.e., SLS) ( 99 ). Recent studies and case reports reported high accuracy levels and patient satisfaction following 3D-printed PSI, rendering 3D printing a valuable tool in up-to-date FFF reconstruction ( 100–102 ).…”
