Monika Elżbieta Machoy, MD, graduated with distinction from the Faculty of Medicine and Dentistry at the Pomeranian Medical University in 2009. She is currently employed as a researcher in the Department of Orthodontics at the same university. Dr. Machoy attended a one-year scholarship program at the Ernst Moritz Arndt University in Greifswald, Germany, and a threeyear internship at the Technical University in Dresden, Germany.

She has been a speaker at numerous orthodontic conferences, including the American Association of Orthodontics, the European Orthodontic Symposium, and the Polish Orthodontic Society. She conducts research focusing on the effect of orthodontic treatment on dental and periodontal tissues and the causes of pain in orthodontic patients.

### Scope of the Series

Biomedical engineering is one of the fastest growing interdisciplinary branches of science and industry. The combination of electronics and computer science with biology and medicine has resulted in improved patient diagnosis, reduced rehabilitation time and better quality of life. Nowadays, all medical imaging devices, medical instruments or new laboratory techniques are the result of the cooperation of specialists in various fields. The series of biomedical engineering books covers such areas of knowledge as chemistry, physics, electronics, medicine and biology. This series is intended for doctors, engineers and scientists involved in biomedical engineering or those wanting to start working in this field.

Preface

Imaging, both two- and three-dimensional, is one of the basic foundations for success in dental work. There are many possibilities in the area of imaging and a variety

As the basis for imaging in dentistry is already digital visualization, it can be used in various devices, including computer tomographs, cameras compatible with systems for creating virtual prosthetic projects, intraoral cameras, and 3D face scanners. All these devices work independently of each other to produce digital images of the patient's mouth, but they can also be used together and thus fully exploit the

of equipment that is at least partially available in every office or laboratory.

The currently available technical and technological imaging techniques have opened up numerous possibilities for creating visualizations useful for dentists and technicians. It is now no longer difficult to obtain a three-dimensional image of a patient's face and profile, which is used, among other reasons, to visualize changes in appearance after prosthodontic or orthodontic treatment. The same is true of obtaining detailed scans of the area to be treated; scanning provides an exact map of the working field, allowing for the planning and implementation of even very difficult dental procedures. Equally available are three-dimensional images of the patient's skull, on the basis of which it is possible to accurately estimate the possibilities of dental implantation. These images help the dentist to plan the depth of implant placement and the angle at which the implants will be inserted into
