Digital Dentistry: From Extraction to Immediate Dentures in a Single Appointment

Immediate Dentures - Digital Dentistry - CE Course
Launch Course

Course Objectives (2 CE Credits)

Siamak Abai, DDS, MMedSc

Digital advancements in areas such as CAD/CAM technology, intraoral scanning and 3-D printing are promoting greater efficiency while expanding the treatment options available to dentists. These tools allow for streamlined care and laboratory protocols that can be modified to meet the individual needs of each patient.

In this presentation, Dr. Siamak Abai outlines a case in which a traditional impression would have resulted in iatrogenic extraction of the patient’s remaining dentition. A model-less workflow is initiated through intraoral scanning, facilitating delivery of immediate dentures and extraction of the patient’s teeth at the same appointment. Topics include:

  • Impression-taking considerations for patients with Class III tooth mobility
  • Treatment planning the delivery of immediate dentures
  • The benefits and applications of intraoral scanning in fully edentulous cases
  • Clinical and laboratory workflows facilitated by digital impressions
  • Traditional and digital techniques involved in the fabrication of dentures
  • Application of CAD/CAM technology in the design and production of restorations
  • The use of pre- and post-extraction digital models in fully edentulous cases
  • Prosthesis fabrication from models produced with 3-D printing technology


The convergence of digital tools and traditional denture fabrication techniques offer dental practices and laboratories a wide range of restorative options for edentulous patients. In some cases, intraoral scanning can reduce the number of appointments and increase the likelihood of patient acceptance of the treatment plan.

With a comprehensive understanding of the options available for producing restorations, clinicians can help ensure that they approach cases in a manner that is as patient-friendly and efficient as possible.

CAUTION: When viewing the techniques, procedures, theories and materials that are presented, you must make your own decisions about specific treatment for patients and exercise personal professional judgment regarding the need for further clinical testing or education and your own clinical expertise before trying to implement new procedures.
