“Background: Within the broad spectrum of rehabilitation, maxillofacial prostheses are those that are made to restore the appearance of a person who has suffered facial deformation due to cancer, accidents, congenital diseases, among others. Although these are not made to restore functionality, they have a major impact on restoring the patient's quality of life as it is an area so closely linked to their identity. For his reason, they have to be carefully tailored for each patient, which tends to increase cost and production time Objectives: The purpose of this research is to compare different additive manufacturing mechanisms, to evaluate which of them achieves the best reproduction of the leather details and maintains the desired dimensional properties. Methods: The manufacturing equipment will be selected comparing 7 different 3D printing of an oculo-palpebral model for a future max...

“Bitemark analysis is a challenging procedure in the field of criminal case investigation. The unique characteristics of dentition are used to find the best match between the existing patterned injury and the suspected perpetrator in bitemark identification. Bitemark analysis accuracy can be influenced by various factors, including biting pressure, tooth morphology, skin elasticity, dental cast duplication, timing, and image quality. This review article discusses the potential of a smartphone camera as an alternative method for 3D bitemark analysis. Bitemark evidence on human skin and food should be immediately recorded or duplicated to retrieve long-lasting proof, allowing for a sufficient examination period. Various studies utilizing twodimensional (2D) and three-dimensional (3D) technologies have been developed to obtain an adequate bitemark analysis. 3D imaging technology provides ...
