Prefabricated Trays Stock for Impression of Cleft lip and Palate Orthopedic Appliances: A Three-Dimensional Computational Analysis of Maxillary Jaws.

Objective: This study aimed to propose digitally designed impression trays, for newborns with cleft lip and palate (CLP) defects, using the computer-assisted design and manufacturing (CAD/CAM) technique, based on measurements of width, length, and height made on processed and scanned plaster models. Thus, we will describe the different software and concepts that can be used for the design of these impression trays.

Design: A total of 59 plaster casts of newborn patients with CLP were collected and then scanned.

[CAD/CAM assisted facial epithesis: Clinical and technical aspects].

The face is an important part of the human body from an anatomical, functional, aesthetic and psychosocial point of view. It can be the site of several mutilations resulting from trauma, treatment of neoplasms and congenital malformations. The plastic facial prosthesis is therefore indicated to restore these facial deformities and to compensate for the various consequences.

Maintaining occlusal stability by selecting the most appropriate occlusal scheme in complete removable prosthesis.

The search of an adequate occlusal scheme that maximizes dentures' stability and patients' satisfaction is an ultimate objective in every complete prosthodontic treatment. Many studies compared occlusal schemes in terms of retention, comfort and masticatory performance. The purpose of this article is to review literature about different occlusal schemes related to complete dentures' stability and edentulous patients' satisfaction, in order to select the most appropriate occlusal scheme.
