Leading researcher Dr. Sergio Uribe, DDS, PhD

ORCID ID: 0000-0003-0684-2025
Dr. Sergio Uribe is a dentist and maxillofacial radiologist. He has defeated Ph.D. and currently works as an associate professor at Riga Stradins University in Riga, Latvia.
Uribe's primary focus is on using clinical and epidemiological study designs, statistical modeling, and artificial intelligence (AI) to improve the diagnosis and treatment of oral conditions, particularly caries, oral cancer, and temporomandibular joint disorders. He is particularly interested in using deep learning and machine learning techniques to analyze dental radiography images for the early detection and prognosis of oral diseases and developing clinical trial protocols incorporating these technologies.


Dr. Ieva Bagante, MD, DDS, Dr.med.

Assistant professor in the department of Oral and Maxillofacial Surgery and Oral Medicine, Riga Stradins University.
Head of the department of Oral and maxillofacial Surgery in P. Stradins Clinical University Hospital.
Oral and maxillofacial surgeon at the Institute of Stomatology and Children's Clinical University Hospital.
Postdoctoral researcher at the Baltic Biomaterials Excellence Centre. Ongoing research on 3D planning of surgical treatment of orbital floor and/or multiple facial fractures.


Doctor of medical science. Certified plastic surgeon – dr. med. Janis Zarins

ORCID ID: 0000-0003-1168-0921
Dr. med. J. Zarins graduated from Riga Stradins university in 2018 becoming a certified plastic surgeon. In 2020, he defended his Ph.D. thesis about bone tissue regeneration and became a Doctor of Medical Science. Dr. Zariņš has been working at the Microsurgery Centre of Latvia since 2013 and has specialized in reconstructive microsurgery for oncological patients, where soft tissue and bone tissue reconstructions must be done after tumor resection procedures. In the head and neck area, complex mandible and maxillary reconstruction are done wh a transplantation of different microvascular flaps.
In the framework of the BBCE project, a contemporary approach is realized for patients with head and neck tumors for better preoperative planning and treatment. Mandible or maxilla 3D models are developed according to radiological examinations. Individual planning is done after oncological principles and patient-specific cutting guides are manufactured with a 3D printer. Virtual preoperative planning provides more options to perform anatomical reconstruction and decreased the time for surgery and improvement of quality of life. Dr. Zarins has specialized in temporomandibular joint (TMJ) reconstruction, where a new reconstructive surgical method has been developed for patients with huge joint, bone, and soft tissue defects. This technique provides autologous reconstruction using only the patient's healthy tissue to replace all lost structures after tumor resection. This technique is promising especially for patients undergoing postoperative radiotherapy.


Medical Engineer: Oskars Radzins

ORCID ID: 0000-0002-2443-9582
Graduated from the University of Glasgow (Glasgow, Scotland, United Kingdom) in 2012 with a master’s degree in biomedical engineering. Recently has started further education as a PhD student at Riga Technical University, faculty of computer science and information technology.
As a medical engineer, the main role within the project is contributing to the transitional point between the physical and digital domains in the healthcare sphere. Some of the primary tasks include data management, computer-assisted modeling, methodology development for conducting digital measurements, object design, and preparation for 3-D printing.
