    3D‐printed shell complete dentures as a diagnostic aid for implant planning and fabricating interim restorations for complete arch rehabilitations: A case series
    (Wiley, 2025) Azpiazu-Flores, Francisco X.; Yang, Chao-Chieh; Lin, Wei-Shao; Polido, Waldemar D.; Morton, Dean; Prosthodontics, School of Dentistry
    3D-printed shell complete dentures generated from a scan of the patient's existing prostheses can simplify and expedite the surgical planning and interim restoration design for complete arch rehabilitations. Three patients were rehabilitated with endosteal implants, and interim restorations were generated from the contours of the 3D-printed shell complete dentures used as diagnostic aids. This case series report presents the recommended protocol and its clinical progression, in addition to clinical and radiographic images of the treatment outcomes.

    Accelerated denture base festooning using a free 3D modeling computer program: A dental technique
    (Elsevier, 2024-05) Azpiazu-Flores, Francisco X.; Morton, Dean; Lin, Wei-Shao; Prosthodontics, School of Dentistry
    Denture bases should be contoured to recreate the natural contours of the tissues being replaced to ensure optimum phonetics, esthetics, and function.1 Several suggestions have been made regarding the desired shape and contours of the artificial root eminences, denture base extension contours, and surface characterization of the denture base.2–4 Traditionally, achieving these contours has been a time-consuming process done manually during the waxing stage of denture fabrication and requiring significant skill and artistry.2

    Expediting the Rehabilitation of Severely Resorbed Ridges Using a Combination of CAD-CAM and Analog Techniques: A Case Report
    (MDPI, 2024-02-02) Jurado, Carlos A.; Azpiazu-Flores, Francisco X.; Fu, Chin-Chuan; Rojas-Rueda, Silvia; Guzman-Perez, Gerardo; Floriani, Franciele; Prosthodontics, School of Dentistry
    With the life expectancy increasing, there is a growing need for prosthetic dental treatments to restore the oral health, function, and quality of life of edentulous patients. Presently, only a few articles are available describing the oral rehabilitation of patients with severely resorbed ridges with milled complete dentures. This clinical case report provides a straightforward protocol consisting of a combination of analog and digital techniques for the rehabilitation of edentulous patients with severely resorbed ridges with milled fixed and removable complete dentures. This technique permits the minimization of the number of appointments, improves patient comfort, allows for the digital archiving of important clinical data, and permits the manufacture of prostheses with improved mechanical properties. These favorable outcomes were achieved by using the patient’s existing PMMA complete denture as a custom tray for a final impression with light-bodied Polyvinylsiloxane. Subsequently, the resulting models were digitized, and a digital complete denture was designed and manufactured in an expedited manner using CAD-CAM techniques. Therefore, this case report highlights the potential of CAD/CAM technology to predictably restabilize oral functions and improve patients’ quality of life.

    Verifying the seating of a 3D-printed removable die using elastomeric matrices: A dental technique
    (Wiley, 2025) Azpiazu-Flores, Francisco X.; Donmez, Mustafa Borga; Lin, Wei-Shao; Morton, Dean; Yilmaz, Burak; Prosthodontics, School of Dentistry
    Computer-aided design and computer-aided manufacturing systems enable digital designing and 3-dimensional (3D) printing of definitive casts with removable dies. However, the fit of the removable dies should be without interferences for their accurate positioning in the cast. Given that the accuracy of additive manufacturing depends on design- and manufacturing-related factors, verifying the accuracy of the position of 3D-printed removable dies in their cast is essential to fabricate positionally accurate definitive prostheses, which would enable minimal or no laboratory and clinical adjustments. This dental technique article presents a straightforward approach to verify the seating of a 3D-printed removable die by using verification matrices made of a polyvinylsiloxane interocclusal registration material.
