Dr. Jakob Zwaan, The Netherlands
Born in 1962 in the Netherlands. Graduated in dentistry in 1987 at the University of Utrecht, NL and emigrated to Italy in the same year. Operating in a private dental office at Calusco d’Adda(BG, Italy) since 1990 as a general practitioner. First approach to periodontal and implant surgery and implant supported prosthodontics in 1993, continuously updating professional knowledge and skills following lectures and attending courses.
Lectures and gives hands-on courses on implant related as well as periodontal plastic surgery subjects since 2007. A strong focus on digital treatment planning aided by all means of digital support systems as intra-oral scanning, cbct-scanning and implant planning softwares. Recently integrated in the clinical protocol calibrated smile design procedures for planning and patient communication. Prosthodontic finalizing of (implant) treatment is ever more shifting to CAD-CAM procedures that perfectly combine with and follow up into digital planning.
Member of the Dutch Society for Periodontology.
Author of clinical follow-up studies on tapered and narrow implants. Currently doing research regarding accuracy of different methods and components for intra-oral scanning.

Course Description
In modern dentistry innovative technologies developed in other industries are being offered and implemented at high speed, causing continuous change of information flow for academic as well as marketing purposes. It can be imagined that people not fully confident with these new, most digital, technologies are confused by sometimes contradictory messages and do not feel comfortable adopting new protocols or investing important sums of money in hardware and software.
During this workshop a team of experts, led by dr Jakob Zwaan, will demonstrate how it is possible to convert traditional diagnostic, surgical and prosthetic protocols into a workflow that is digitized to the optimal level without compromising safety for the patient and quality and accuracy of the final result. Also will be highlighted how it is possible to integrate step by step new tools without abandoning completely the precious experiences built up during our professional careers.
Delegates will be shown how dr Zwaan’s team approaches patient intake and diagnostic phase with the means of clinical, radiological and esthetic analysis. In the next step they will learn how to perform Smile Design 2D based on a simple photo protocol. Calibration and transmission into the laboratory of measurements of the newly designed smile are essential. The dental technician will then translate this information in a traditional or a digital CAD wax-up and successively produce a silicon index necessary for mock-up in the mouth. Delegates will learn how to edit video’s of the patient before treatment and the patient with the mock-up. The mock-up will be used as a 3D digital file that can be imported and matched with DICOM from CT-scan so that (implant-) treatment planning can be really prosthetic driven. Criteria to opt for guided surgery as well as how to design and produce a surgical template will be illustrated. Also different prosthetic components available in company libraries can be used to optimize treatment planning, taking into account also the possibility of up to 25° angulated access holes for screw retained CAM devices. In the end the opportunity is offered to experience the use of an intraoral scanner and also will be shown how certain strategies and tools can optimize chairside time and patient comfort.

Course Objectives
Demonstrate delegates how data are collected and elaborated into a “multi-layer” digital environment for diagnosis, esthetic analysis and treatment planning
Understanding of each aspect from the point of view of the prosthodontist, the orthodontist, the surgeon and the dental technician and how these specialist can interact
Show a completely open workflow so that each participant can decide for his own practice which digital tool to implement and what part of his/her traditional protocol to maintain
Highlight the importance of Smile Design and discuss how photo- and video imaging can be applied to optimize treatment as well as communication with the patient
Promote a rational discussion about guided surgery, choice of material and methods for prosthesis
