Implant 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 welldesigned 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 the all-ceramic restorations produced in 2010, zirconia based units represented approximately 50% of that total. The introduction of computer aided design/ computer aided manufacturing (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 isn’t the future. Far from it 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.

She joined the Prosthodontic Department of Alzahraa University Hospital-Al-azhar University in Egypt from 2002 until now. She has also worked as a Lecturer Assistant at Miser University For Science and Technology . She received her Master’s Degree in Prosthodontics from Al-azhar university in 2009 and she accredited it from Educational Credential Evaluators, USA .Currently she is pursuing her Phd degree. She is a member of AACD as well as AAID and DSD Certified Member. She was a Participant Speaker lately in FDI World Dental Congress 2016 at Poznan. She is interested in cosmetic cadcam dentistry with special interest in color and implant supported restorations. She has her own private clinic and studio in Cairo in which she treats cases in co-operation with many international smile designers and technicians. Also, she is the Co-founder in Digital Reverse Engineering Academy which implies a very recent and unique theory in digital dentistry.
