Clinical report
A 65-year-old woman had been edentulous for 12 months and had been treated with mucosa-supported complete dentures. Her chief complaint was the inability to masticate comfortably because of her loose mandibular denture. She requested an IFCDP and new complete maxillary denture. She reported smoking 10 cigarettes a day but was otherwise healthy and not taking any medication. Initial prosthodontic and radiographic screening revealed favorable conditions for an implant-supported prosthesis (Fig. 1
Discussion
Promising concepts for optimizing patient comfort by combining a minimally invasive surgical approach with a fixed implant-supported reconstruction are underrepresented in the literature. The provision of 10 edentulous patients with a cross-arch fixed prosthesis has been described in a recent case series.10 Two 10-mm RN implants were inserted in the anterior area of the mandible and then splinted to 4 extrashort RN implants (4-mm endosseous length) in the posterior area of the mandible. The
Summary
The described treatment approach demonstrated the clinical feasibility of providing atrophied mandibles with IFCDPs supported by a combination of anterior regular and distal ultrashort tissue-level implants. This approach combined the advantages of a simplified prosthetic treatment concept: virtual prosthetic and surgical planning, s-CAIS, and novel CAD-CAM–supported complete-arch reconstruction. Thus, it may offer improvements when dealing with challenging anatomic, surgical, and prosthetic
