RESUMEN
The present study measured removal torque and bone-implant interface resistance of machined implants, acid-etched implants, or machined implants irradiated around the implant area with infrared low-level laser therapy (LLLT; 830 nm) immediately after surgery. There were statistically significant differences between Groups A (control) and B (rough surface) (P = .03). Implants with a rough surface seem to add resistance to the bone-implant interface compared with smooth titanium implants or implants treated with LLLT.

Treatment of facial trauma sequelae is a complex and challenging process. There is still controversy over suitable materials for orbital wall reconstruction. This study evaluated calcium phosphate cement (CPC) implants manufactured by rapid prototyping in the repair of orbital wall defects secondary to trauma. Computed tomographic scans of 5 patients were used for surgery planning and production of CPC implants. Implants were used to restore orbital wall anatomy, ocular alignment, and facial contour. Benefits resulting from the use of implants, such as a reduced operating time, patient response to biomaterial implantation, biomaterial integrity and stability, and patient satisfaction with treatment, were analyzed qualitatively. Our results suggest that CPC is an effective and safe material for orbital reconstruction because of its biocompatibility and easy production and placement.
