Computed tomographic scan showing all 3 dimensions sagittal, coronal, and axial of the orbitofacial defect as a preliminary step in the formation of a biomodel. Photographs of a 3-dimensional 3-D computed tomographic biomodel with a polymethyl methacrylate PMMA implant. A, Front view of the biomodel shown in violet with the PMMA implant shown in green covering the orbital defect. B, Diagonal view of the same biomodel and implant demonstrating the 3-D effect and showing depth and dimension of the implant, which is fitted into the defect. The prefabricated PMMA implant front [a] and diagonal [b] view is constructed using computer-generated data and the biomodel.

HTR-PMMA is a technology-driven, cranial patient-matched implant designed to achieve cosmesis of the skull resulting from tumor, trauma, or deformity. These images are used to create anatomical models, which are then used to build the patient-matched implants. They are intended to fill voids or defects in bone resulting from disease, traumatic injury or surgical trauma. These devices can be used in aesthetic reconstructive procedures where augmentation or change in bony contours is desired. Hydrophilic Allows for placement of implant into antibiotic solution pre-operatively; enables vascular flow post-operatively. Previous page.
HTR-PMMA Patient-Matched Implant
This ultra aesthetic temporary material combines 5 plus layers of colors into one disc, giving the restoration the most natural look possible. The top of the gradient disc is lighter and very translucent incisal and gradually shades down to the bottom that is darker cervical. This, in combination with a unique polymerization molding technology, creates the ideal material properties of the PREMIOtemp blanks.
The Polymer Expansion Implant System, which is a system for the substitution of missing dental roots in natural or surgical alveolus, has been developed by the author. The polymer used is poly methyl methacrylate PMMA. A material is sought that has three of the basic physical and mechanical qualities of human dentine: low modulus of elasticity, thermal and electrical passiveness, and ideal porosity.
