In general terms, the best rehabilitation options for patients previously subjected to hemi-mandibulectomy are far beyond their financial possibilities. For this reason surgical-prosthetic reconstructive approach is mainly restricted to the use of more affordable materials such as Kirschner wire and methyl-methacrylate immediate prostheses. The latter are widely recommended due to their low cost, ease of handling, and because they prevent soft tissue atrophy. A clinical case is reported in this article: 25 year old male patient seeking treatment at the Oncology Service of the Hospital General de Mexico (Mexico's General Hospital) due to the presence of a volume increase in the area of the left mandibular angle. Microscopic analysis revealed presence of mixed malign tumor ( final histopathological diagnosis). It was decided to perform hemi-mandibulectomy of involved area, with reconstruction of lost bone segment by means of positioning an immediate methyl methacrylate prosthesis (thermosetting methyl). The prosthesis was fixated with osteosynthesis wire at both resection margins, at 3 mm above the cortex.
