OBJECTIVE Disinfection procedures often cause deterioration in a maxillofacial prosthesis. Color and hardness alterations could lead to a replacement of the prosthesis. MATERIAL AND METHODS An experimental chlorinated polyethylene (CPE) and a commercial polydimethyl siloxane (PDMS) sample were treated with four different disinfection procedures for a period which simulates 1 year of clinical ...

Techniques of rapid prototyping were introduced in the 1980s in the field of engineering for the fabrication of a solid model based on a computed file. After its introduction in the biomedical field, several applications were raised for the fabrication of models to ease surgical planning and simulation in implantology, neurosurgery, and orthopedics, as well as for the fabrication of maxillofaci...

STATEMENT OF PROBLEM The clinical life of a maxillofacial prosthesis averages about 6 months, before it needs to be refabricated. Degradation of the color and physical properties of the prosthesis are the principle reasons for replacement. PURPOSE This second part of a 3-part in vitro investigation evaluated the change in physical properties of popular colorant-elastomer combinations as a res...

In the present study, the growth of a single isolate of Candida albicans on saliva-, serum-coated or protein free (uncoated), thermocycled (4-70 degrees C for 1 min, respectively; 0, 1000 and 10 000 times) 15 commercial maxillofacial materials was investigated, by monitoring pH changes in growth media. The inhibitory effect of the tissue conditioners on fungal growth was analysed using three pa...

Mucormycosis is an opportunistic fungal infection, which mainly affects immunocompromised patients. Once the maxilla and orbit are involved, surgical resection debridement of necrosed areas can result in extensive defects .in prosthetic rehabilitation such cases major challenge replacement misssing soft hard tissues following resection. Hence acceptable becomes a to maxillofacial prosthodontist...

This clinical report describes the multidisciplinary approach in the maxillofacial rehabilitation of a 7-year-old boy diagnosed with osteosarcoma of the mandible. Following surgical resection of the left half of the mandible from the angle to the parasymphyseal region, a free osseocutaneous flap from the fibula was used to successfully reconstruct the mandible. Dental implants were subsequently...

PURPOSE The aim of this study is to present the development of a new technique to obtain 3D models using photogrammetry by a mobile device and free software, as a method for making digital facial impressions of patients with maxillofacial defects for the final purpose of 3D printing of facial prostheses. METHODS With the use of a mobile device, free software and a photo capture protocol, 2D c...

Augmented reality refers to: “a technology that superimposes a computer-generated image on user’s view of the real world, thus providing composite view”. It has become resourceful in many fields including dentistry and medicine. Currently augmented is restricted to education, maxillofacial surgeries implantology but further research development can expand its uses other critical areas. In prost...
