Aim The present article describes a simplified protocol based on a digital workflow used for a patient rehabilitation from immediate pre-extraction (ID) to definitive complete dentures (DD).

Materials and Methods A 67 year old patient previously rehabilitated with removable partial dentures (RPD) referred to Siena University Prosthodontic Department complaining functional and aesthetic discomforts. The anamnestic data and photos were collected at the fist visit. The clinical observation and x-ray evidenced an hopeless dentition in both arches due to stage IV periodontal disease. Digital intraoral and bite scans were recorded with and without the existing Removable partial denture (RPD) for case study. The treatment plan included the extraction of all residual teeth and the delivery of ID maintaining the previous inter-maxillar relationship and all the aesthetics parameters. The ID were obtained by a single step milling procedure (Ivotion,Ivoclar Vivadent AG, Liechtestein)and after healing at 9 months it was decided to scan the relined ID in order to reproduce the cameo surface and tooth arrangement required for a new DD fabrication.

Results The patient was collaborative during all treatment, reported a positive adaption from the ID delivery, a good aesthetic integration and optimal functional comfort even with DD.

Conclusions The digital workflow for complete dentures fabrication requires limited time and effort compared to conventional protocols. Thanks to the digital workflow the patient obtained a good adaptation to the prostheses and an enhanced aesthetics and functional results. The authors have no conflicts of interest to declare.
