Impact on quality of life and oral health in edentulous patients rehabilitated with implant-supported complete dentures - All-on-Four technique

Abstract

This study addresses the impact on quality of life and oral health in edentulous patients rehabilitated with implant-supported complete dentures using the All-on-four technique. The aim was to analyze the functional, aesthetic, and psychosocial benefits provided by this therapeutic approach, highlighting its relevance in the oral rehabilitation of individuals with total tooth loss. The research is characterized as a qualitative, descriptive, and exploratory literature review, developed from the analysis of scientific articles published in national and international dental databases. Studies related to implantology, oral rehabilitation, quality of life, and the All-on-four technique were selected, prioritizing recent and relevant publications. The results showed that the All-on-four technique presents high clinical predictability and high success rates in the rehabilitation of edentulous maxillae, providing significant improvement in mastication, phonetics, prosthetic stability, and facial aesthetics. It was also observed that the distal inclination of posterior implants favors better biomechanical distribution of masticatory loads, reducing the need for bone grafts and minimizing surgical morbidity. In addition to functional benefits, the analyzed studies demonstrated positive impacts on patients' self-esteem, self-confidence, and social interaction, directly reflecting on their oral health-related quality of life. Important contributions of digital planning and guided surgery techniques to increased surgical precision and treatment predictability were also identified. It was concluded that the All-on-four technique constitutes a modern, safe, and effective therapeutic alternative for the rehabilitation of completely edentulous patients, promoting functional, aesthetic, and psychosocial recovery. Thus, implant-supported treatment is not limited to tooth replacement but significantly contributes to the physical, emotional, and social well-being of rehabilitated individuals.
