ABSTRACT
Introduction: Facial defects can affect the appearance of an individual, resulting in psychological and social
problems. In certain cases, surgical reconstruction of facial defects may not be feasible and prosthodontic
rehabilitation may be the best option. Case description: A 72-years old gentleman was referred for the
rehabilitation of a facial defect on the right side of his nose. The defect was affecting him psychologically and
socially. The decision was made to construct a nasal prosthesis for him that would be retained by desirable
undercuts and adhesive. Discussion: Management of facial defects are challenging due to multiple reasons such
as matching of the prosthesis to surrounding skin and retention of the prosthesis. The prosthesis can be retained
with implants, facial accessories, desirable undercuts, or adhesives. For this patient, the prosthesis was retained
by using undercuts combined with medical-grade adhesive. A thin layer of flash at the edges of the prosthesis was
maintained to ensure even finish margin. The prosthesis fabrication successfully resolved the patient’s condition.
Anthropometry is defined as the scientific study of the measurements and proportions of the human body. To date, the most used methods for the acquisition of facial anthropometric parameters are direct method employing calipers and protractors tools, which are time-consuming, or indirect methods employing three-dimensional (3D) imaging systems, which are expensive. Despite the possible advantages of two-dimensional (2D) photography, it is not widely explored due to complications such as resolution and distortion of digital photos. The objective of this study is to
assess the accuracy of the Digital Single-Lens Reflector (DSLR) camera as an indirect method against direct method at different aperture and distance to subject. Adults aged 20-45 years were voluntarily recruited in this study (n=24). Twelve facial anthropometric parameters were measured for each participant using direct anthropometry (sliding caliper), and indirect anthropometry (DSLR camera). When placing the DSLR camera at 2.0 meters from subjects with f/6.3 aperture, nine facial anthropometric parameters were obtained accurately (p> .05). The findings suggested that
the accuracy of the DSLR camera as an indirect method for the acquisition of facial anthropometric parameters was established at the aperture setting of f/6.3 and the object distance at 2.0 meters. Therefore, it can be recommended as a facial anthropometry acquisition technique.
