From Intraoral Scan to Custom Implant Restoration
Digital technology continues to revolutionize modern dentistry,
benefitting every phase of treatment from diagnosis to final restoration.
Here, Dr. Perry Jones demonstrates the use of an intraoral optical
scanning system, followed by the CAD/CAM design and milling
of all-zirconia custom abutments and a monolithic zirconia bridge,
to precisely restore a historically problematic anterior case.
Implant Q&A: Interview with Dr. Michael McCracken
Ongoing studies have revealed correlations between tooth loss and
systemic health issues such as gastrointestinal disorders, atherosclerosis,
or even cancer. In this interview, prosthodontist and University
of Alabama School of Dentistry professor Dr. Michael McCracken
discusses the use of dental implants to stave off resorption, access to
treatment, and various restorative options available today.

Delivery of a Mini Implant-Retained Overdenture
Though mini implants are designed to accommodate the immediate
loading of an existing denture in the presence of primary stability,
patients are often better served by the fabrication of a prosthesis
specifically fitted for the new biologic form factor. Dr. Christopher
Travis outlines the process of providing a new overdenture designed
for optimal function and esthetics following the osseointegration of
four mini implants.
Implant and Mandibular Canal Mapping
Three-dimensional CBCT images have a wide range of diagnostic
and treatment planning uses, and are quickly becoming a standardof-care
practice in implant planning. Using an illustrative case report,
Dr. James Jesse describes how the latest 3-D imaging technology can
help to produce safer, more predictable treatment outcomes.
Zirconia Crown Esthetics and Optical Properties
With their flexural strength, fracture toughness and toothlike esthetics,
monolithic crowns & bridges milled from zirconia are increasingly
being used as alternatives to traditional PFM restorations. In
this scientific overview, Glidewell Laboratories’ Ken Knapp explains
how the future of zirconia as a restorative material is rooted in the
efforts of material scientists to engineer nanocrystalline structures
that better approximate the optical translucency of natural dentition.
