Part 1
The maxillary sinus in 3D - what dentists need to know
One of the main reasons for CBCT imaging in dental medicine is the assessment of the residual ridge and maxillary sinus prior to sinus floor elevation (SFE) procedures for dental implant placement. Cross-sectional imaging (CBCT) has been recommended for pre-operative evaluation of the available bone in the posterior maxilla and assessing health or pathology of the maxillary sinus. The most common anatomic variation in the maxillary sinus is the thickness of the Schneiderian membrane. Furthermore, septa within the maxillary sinus are common findings. The presence of septa has been related to an increased risk for perforation of the Schneiderian membrane during SFE. Thus, detailed knowledge of the anatomic structures of the maxillary sinus and related sinonasal areas seems to be beneficial prior to SFE to avoid surgical complications, which ideally is gained radiographically by the use of CBCT scans. In clinical situations when there is evidence of sinus pathology, or when the clinician believes that sinus drainage is impaired and may jeopardize the outcome of the prospective implant procedure to be undertaken, it seems advisable to consult an ear, nose, and throat (ENT) specialist.

 Learning Objectives:

  1. Know the normal anatomy of the maxillary sinus as seen on 3D imaging (CBCT)
  2. Know the most common pathologies as seen on CBCT imaging
  3. Know the clinical relevance of assessing health versus pathology of the maxillary sinus for dental medicine / oral surgery / oral implantology

Part 2
Non-plaque-induced gingival diseases - a clinically relevant overview
In 2017 the American Academy of Periodontology (AAP) and European Federation of Periodontology (EFP) co-presented the new classification for periodontal and peri-implant diseases and conditions at the world workshop. While plaque-induced gingivitis is one of the most common human inflammatory diseases, several non-plaque-induced gingival diseases are less common but may be of major significance for patients. Non-plaque-induced gingival lesions are often manifestations of systemic conditions, but they may also represent localized pathologic changes limited to gingival tissues. The novel classification is based on the etiology of the lesions and includes: genetic/developmental disorders; specific infections; inflammatory and immune conditions and lesions; reactive processes; traumatic lesions; gingival pigmentation, neoplasms. The present lecture will focus on the most commen and also clinically relevant non-plaque induced gingival diseases. Furthermore, diagnostic options and also relevant differential diagnostic options will be discussed.

Learning Objectives:

  1. Know main groups of non-plaque induced gingival diseases
  2. Know how to differentiate between systemic and local causes for gingival lesions based on clinical inspection
  3. Know diagnostic options available to reach a final diagnosis
  4. Know when and to whom to refer patients to with non-plaque induced gingival diseases



Michael Bornstein has been appointed in January 2020 as professor and chair of the Departement of Oral Health & Medicine at the University Center for Dental Medicine Basel (UZB) of the University of Basel, Switzerland. Since April 2020 he is also head of "research" and member of the executive board at the UZB.

He obtained his dental degree (1998) and thesis (Dr. med. dent., 2001) at the University of Basel. He continued with a specialisation in oral surgery and stomatology in Basel (1998-1999, Prof. Dr. Dr. J. Th. Lambrecht) and Bern (2000-2002, Prof. Dr. D. Buser). In 2004, he was visiting assistant professor at the Department of Periodontics (Prof. Dr. D. Cochran) at the University of Texas Health Science Center at San Antonio, USA, with a grant from the Swiss National Science Foundation. From 2007-2014 he was head of the Section of Dental Radiology and Stomatology, University of Bern. In 2009, he obtained the Habilitation (Privatdozent / PhD) and in 2014 he became Asscociate Professor in the field of „Oral Surgery and Stomatology“.

From 2016-2019 he has been Clinical Professor in Oral and Maxillofacial Radiology at the Faculty of Dentistry, The University of Hong Kong, Hong Kong SAR, China. In December 2018 he is been appointed as Associate Dean of "Research and Innovation" of the Faculty of Dentistry. He currently is a Visiting Professor at the OMFS-IMPATH Research Group, Department of Imaging and Pathology, University of Leuven, Belgium, and since January 2020 a Honorary Professor of the Faculty of Dentistry, The University of Hong Kong.

His fields of research include cone beam computed tomography (CBCT) in clinical dental practice, diagnostic imaging, stomatology/oral medicine, GBR procedures and dental implants. He has published 190 original articles, and is the author / co-author of numerous case reports, review articles, and book chapters.
