NCT05322226
Addiction care is "a la carte treatment", adapted to the motivation and time constrains of users. Thus, various types of psychotherapeutic follow-up can be considered, different addictolytic medications or opioid maintenance therapies can be offered during treatment and hospitalization must be adaptable. In liver transplantation (LT), sustained alcohol relapse is a critical issue because it increases medium and long-term morbidity and mortality. In recent years, the issue of severe acute alcoholic hepatitis as an indication for LT has necessitated increased focus on appropriate alcohol monitoring around liver transplantation. Previously, alcohol consumption in pre- and post-LT period was mainly self-reported. More recently, the biological markers of excessive alcohol consumption have been validated in liver disease and can play a role in liver transplant recipients follow-up. The investigator hypothesize that standardized targeted addiction monitoring of LT patients decreases the rates of sustained alcohol relapse one year post liver transplantation.

This prospective observational clinical study aims to evaluate the three-dimensional surface wear and clinical survival of orthodontic attachments fabricated with customized composite materials used in clear aligner therapy. Attachments play a critical role in the biomechanical efficiency of aligner treatment by facilitating planned tooth movements. However, the mechanical and surface properties of the composites used for attachment fabrication may affect their wear behavior and long-term stability. In this study, four different composite materials will be tested using a split-mouth design in patients treated with clear aligners. Each quadrant will receive a different composite, including both customized and universal types. All attachments will be fabricated using standardized digital templates and bonded under identical clinical conditions. Surface wear will be evaluated using three-dimensional optical scanning and metrology software at baseline, 1 week, 1 month, 3 months, and 6 months. Lost attachments will be replaced and recorded but excluded from wear analysis. The results of this study are expected to provide valuable insights into the optimal material selection for clear aligner attachments, improving treatment accuracy and clinical durability.
