Conditions
Summary
This clinical study aims to evaluate the effectiveness of patient-specific 3D-printed titanium facial implants in the reconstruction and aesthetic correction of facial defects. The study will include patients presenting with congenital, traumatic, or post-surgical facial deformities requiring reconstructive intervention. Eligible participants will undergo preoperative clinical assessment and radiological imaging to design customized implants using computer-aided design (CAD) and 3D printing technology. The implants will be fabricated from medical-grade titanium and surgically placed according to standardized maxillofacial reconstructive protocols. Postoperative follow-up will assess functional outcomes, implant stability, complication rates, and aesthetic improvement over a defined observation period. Outcome evaluation will include clinical examination and patient-reported satisfaction measures. The objective of this study is to determine whether patient-specific 3D-printed titanium implants provide reliable functional restoration and improved aesthetic outcomes in facial reconstruction compared to conventional reconstructive techniques.

Interventions
Patient-specific 3D-printed titanium implants will be used for reconstruction of facial bone defects and correction of facial deformities. Each implant will be individually designed based on high-resolution computed tomography (CT) imaging and three-dimensional virtual surgical planning (VSP) using computer-aided design (CAD) software to accurately match the patient's anatomical defect. The implants will be manufactured from medical-grade titanium alloy (Ti6Al4V) using selective laser melting (SLM) additive manufacturing technology. Post-processing will include surface finishing and sterilization prior to surgical use. Surgical placement will be performed under general anesthesia following standard maxillofacial surgical protocols. The customized implants will be fixed to the native bone using titanium fixation screws when required to restore facial contour, structural support, and symmetry. Postoperative follow-up will include clinical and radiological assessment using CT imaging t
