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.
Résumé
Objective@# To provide a clinical reference by evaluating the restorative results of an accurate impression technique for distal-extension removable partial dentures.@*Methods@#Forty-two patients with free-end dentition defects who visited the Prosthodontic Department of Nanjing Stomatological Hospital, Medical School of Nanjing University, between April 2017 and January 2018 were selected. The final impression was made by an accurate impression technique to fabricate fifty-two removable partial dentures with casting frameworks. The restorative result was judged by clinical examination and patient feedback immediately after wearing dentures and at 1 week, 3 months and 6 months.@*Results@#All fifty-two dentures for forty-two patients were seated successfully, with good retention and stability. Complications occurred throughout the 6-month follow-up, including 4 cases of mucous pain, 4 cases of retention force attenuation and 1 case of abutment fracture. There were no periodontics problems. The dentures garnered high patient satisfaction.@*Conclusion@#The accurate impression technique for distal-extension removable partial dentures showed good clinical results in this follow-up investigation.
