3D Facial Scanning: Dual-Arch Fixed Prostheses From Diagnosis to Delivery.

Three-dimensional (3D) facial scanners can be used to effectively and accurately diagnose, treatment plan, design, and deliver dental prostheses. The use of 3D facial scanning enables clinicians to replicate a patient's face 3-dimensionally in various lip positions to facilitate full-arch dentistry. Digitally replicating the face gives the clinician and technician the ability to visualize different possible lip positions.

Managing Ridge Resorption After Tooth Extraction Using Partial Extraction Therapy.

Achieving successful long-term esthetic outcomes in implant dentistry requires that the height and width of the facial or buccal alveolar bone wall and, subsequently, the peri-implant tissues be maintained. Partial extraction therapy (PET) can be used to reduce the risk of facio-lingual collapse after tooth loss and improve the preservation of alveolar bone height and blood supply. This article demonstrates the use of PET for treatment of a hopeless tooth in the esthetic zone.
