In this paper, we establish a procedure for the enhancement of cone-beam computed tomography (CBCT) dental-maxillofacial images; can be useful in order to face problem rapid prototyping, i.e., generate 3D printable file dental prosthesis. proposed procedure, crucial role is played by so-called sampling Kantorovich (SK) algorithm reconstruction and image noise reduction. For latter algorithm, it...

Aim. This study aims to explain the main steps that characterize the implant-prosthetic rehabilitation in complex combined dental and maxillofacial trauma. Material and Methods. A 20-year-old patient reported an extensive facial trauma which also involved the alveolar process of the maxillary bone. The patient reported a maxillofacial fracture and the loss of teeth 1.3, 1.2, 1.1, and 2.1. A "Le...

The present study analyzed stress distributions in craniofacial structures around implant-supported maxillary prostheses. Using post-hemimaxillectomy computed tomography (CT) of a patient, the authors constructed a three-dimensional (3D) solid model using Digital Imaging and Communications in Medicine data (DICOM data) for maxillofacial and cranial bones. The effects of different prosthesis des...

Patients with a tracheostomy stoma experience compromised speech and function due to the associated changes in airflow patterns. Rehabilitation of a patient with tracheal stoma is a highly challenging task. The main objective is to design an inexpensive, easily fabricated stomal prosthesis for postlaryngectomy patients who require prolonged tracheotomy. This clinical case report describes a 29-...

PURPOSE Maxillofacial silicone elastomer is usually colored intrinsically with color pigments to match skin colors. The purpose of this study was to investigate the color stability of a maxillofacial silicone elastomer, colored with a thermochromic, color changing pigment. MATERIALS AND METHODS Disc-shaped maxillofacial silicone specimens were prepared and divided into 3 groups: a conventiona...

Ultrahigh molecular weight polyethylene (UHMWPE) having a low coefficient of friction (CoF), high wearand chemical resistance in harsh environments, is used for fabricating medical products (hip and knee joints, intervertebral discs, plates for maxillofacial surgery, and others). Priority of polymers, in particular UHMWPE to be applied as medical implant materials, is due to their proximity to ...
