Résumé
Objective@#The present study investigated the clinical effects of a single complete denture using two-step fine impression during the restoration of mandibular alveolar ridge atrophy. @*Methods @#A back-end window tray that was personalized and adjusted was used to obtain the original impression for a mandibular alveolar ridge case. The individual trays were made with the conception of mandibular occlusal denture, and the final impression was obtained after active edge shaping using different viscous silicones. @*Results @#A case of single complete denture with mandibular alveolar ridge atrophy restoration was accomplished using a single complete denture and two-step fine impression. The denture was well fixed and functioned well, and the patient was satisfied.@*Conclusion @#The application of fine impression into a single complete denture is helpful for the restoration of mandibular alveolar ridge atrophy.
