mplant dentistry has seen rapid and remarkable progress in recent years. Several questions have been raised concerning materials
as well as designs of both implants and implant abutments to achieve maximum clinical success rates. An understanding of their
properties will help the clinician in selecting the ideal prosthesis for each clinical case, while promoting final esthetic outcomes. With
the evolving technology and knowledge, an update of the current trends is necessary. The use of implants to replace missing teeth in
the esthetic zone is challenging. The restorations are subjected to direct visual comparison with the adjacent natural teeth. Perfect
three dimensional implant positioning and well-designed superstructures are therefore essential to mimic the appearance of a natural
tooth and to achieve an optimal esthetic outcome. The development of computer aided design, computer aided manufacturing (CAD/
CAM) technology has focused on precise and consistent manufacturing of zirconia ceramics with high strength and toughness.
CAD/CAM technology relies on exact dimensional predictions to compensate for sintering shrinkage, and is an economical and
highly reproducible method for manufacturing complex and individual geometrics from a green or presintered ceramic material.
Zirconia has become one of the dominant types of ceramic used for a variety of CAD/CAM restoration classes, including framework/
hand veneer, framework/pressed veneer, framework milled/veneer, full contour fixed prosthodontics, implant abutments, and large
implant supported substructures. Although zirconia is currently the strongest dental ceramic material available, fabrication variations
and finishing procedures can affect the longevity of this material as well as the veneer porcelain. Having a good working relationship
with a dental laboratory is strongly recommended. Of all-ceramic restorations produced in 2010, zirconia based units represented
approximately 50% of that total. The introduction of CAD/CAM has facilitated the use of superior dental ceramic, to enhance the
fabrication of consistent and predictable restorations in terms of strength, marginal fit and esthetics. CAD/CAM technology in
combination with zirconia ceramic has increasingly gained popularity in implant dentistry. Marginal accuracy, retention and color
matching of esthetic implant supported crown are critical determinant in the over all success of implant therapy and yet it remains
challenge. Especially with the innovative revolution of CAD/CAM systems designs and materials which has improved and refined
endlessly. So on understanding of their properties is a demand for helping the clinician in selecting the ideal prosthesis for each
clinical case while promoting final esthetic outcomes. In this lecture we will spot light in a comparative way between different CAD/
CAM techniques [Full contour CAD/CAM technique, Anatomical core CAD/CAM technique, over press CAD/CAM technique].
We will show their marginal accuracy, color matching and retention when used as a cemented versus screw retained esthetic implant
supported crowns. Digital implant dentistry is the “here and now” for dental implant practitioners. From digital treatment planning
and delivery to patient communication, new technologies are changing the way dentists practice implant dentistry. The digital
advancements in dentistry are growing at an incredible speed.
