Good afternoon, ladies and gentlemen. My name is Katarzyna Maciejewska. I am oral surgeon and I am Bicon opinion leader in Poland. Together with my co speaker, Dr. Michał Drozdowski, I will have a pleasure and honor to present Bicon implants by consistent presence in our country. Bicon has started its activity in Poland in 2009. Since beginnings, activity, was focused on two areas. The first of them is promotion by consistence in Poland, and the second, education and trainings. Over this fifteen years, we managed to introduce Bicon system across the country. You can see location, dental clinics and prosthetics laboratories in Poland, working with Bicon system. We are present in the most of big cities and municipal areas. Started from 2009, we organized over one hundred sixty full day trainings and many advanced courses. During basic courses 900 dentists were trained, which were introduced to Bicon system and inserted over 700 implants. And advanced courses, we were dedicated to dentists already using Bicon implants in their day to day work. The most interesting cases were the cases of advanced atrophy of the maxillary alveolar process with very close contact with the maxillary sinus. With the minimal amount of bone of about 1–3mm. Implantation procedure, were performed using internal elevation of the maxillary sinus floor using crestal sinus lift technique. CGF, only was used during this procedure. The venous blood from the patient was collected, the plasma was centrifugated, and faced with the growth factors and stem cells, was used under, moved the pieces of crestal bone. The implants were inserted with the sinus lift temporary abutments. The first patient was the man, thirty seven years old, without first maxillary molars. The first of them, on the right side, he lost five years before. The lowest bone height measurement was one and a half millimeter. CBCT examination didn’t reveal any pathology in the maxillary sinus. The patient was qualified to the Crestal sinus lift procedure. The procedure was performed without problems, without complication, with the CGF from blood patients patient. Implant six by five was inserted with the sinus lift temporary abutment. After five months after surgery, the implant was uncovered and a temporary abutment was inserted. And now, after eight years working implant with the integrated abutment crown, the X-ray examination showed the stability of the prosthetics reconstruction and stable level bone, about seven millimeter high. The same patient on the left side, three years after he first molar was lost. The lowest bone height was one point seven millimeters. In the same time, the same procedure was performed. Implant four and half by five was inserted with the sinus lift temporary abutment. The the treatment was without complication. After five months, implant was uncovered and temporary abutment was inserted. On the X-ray examination, visible level bone of new bone formation is about seven millimeters. CBCT examination in this year was performed, showed the same bone level. The next patient was the woman, forty one year old, without right molars in the maxilla. Ten years after extraction, the residual bone had only about two millimeters. The crestal sinus lift procedure with the CGF was performed. The implant six by five inserted with the sinus lift temporary abutment in position first molar. Eight years after loading, implant height of bone around the implant is over seven millimeters. The longest observation, the longest follow-up, fifteen years, relate to women four to five years old without the molars in the maxilla, with the distance two millimeters to the maxillary sinus. Fifteen years after loading implant six by five point seven with the integrated abutment crown, the height of newborn formation is over seven millimeters. The next patient was woman sixty thirty six years old, implant four and a half by six with the sinus lift, temporary abutment was inserted during the crestal sinus lift procedure with the CGFP. CBCT examination after fifteen years after loading implant shows over seven millimeters newborn versus five millimeter two millimeters before before surgery. During the advanced courses, over one hundred implantations were performed. All of implants were inserted with the crestal sinus lift procedure. From all of them, only two implants were lost at the integration stage, and only one of them was lost five years after loading. The presented cases, example of cases with the crestal sinus lift technique using venous blood plasma shows the stability of the prosthetics reconstructions and the stable level of new bone formation in time. Another challenge in implantology is the narrow alveolar process. A few words about this will tell you Dr. Michał Drozdowski. Michał, the floor is yours. Thank you. Thank you very much doctor. My name is Michał Drozdowski. I’m an oral surgeon. My name is Michał Drozdowski. I’m a oral surgeon. Katarzyna is my first teacher of the Bicon system. I’ve been working with Bicon implants for nine years. Currently, is the only implant system I work with. Ladies and gentlemen, I would like to present two cases of an edentulous treatment with full arch work based on Bicon implants. Sixty three years old patient, lady, implantation of Bicon implants in location thirty three and forty three after splitting the mandible. Proceeded by piezo surgical preparation. The time for piezo preparation to implantation procedure is six weeks. The time from procedure to the unveiling of the implants is four months. Returning the prosthetic work with two Brevis abutments after two months. Observation period one year from completion of work and eighteen months from implantation. Area thirty three before the procedure. In the implanted section, the mandible is fifteen millimeter high, but very narrow in the vestibular lingual dimension. Controlled CBCT in area thirty three after preparation. Mental foramen. It’s the same area from another side. After preparation for splitting with a piezo surgery, and splitting and insertion of implants, sorry, after six weeks. In the first stage, the mandible was prepared for splitting by cutting the lingual plate on both sides at the dimension of ten by ten millimeter. Area thirty three, condition after implantation. Bicon implant three point zero by six point zero. Date of implantation, May twenty nine twenty twenty three. Before, after. Area forty three before the procedure. Controlled CBCT in the area forty three after preparation with piezo surgery for splitting. Splitting and insertion of implants after six weeks. Opposite side, area forty three condition after implantation. Bicon implant three point zero by eight point zero. Date of implantation, May twenty nine twenty twenty three. Before, after. The oral cavity after healing of the mucous membrane with Brevis abutment installed. Date of installation of Brevis connectors, October the second 2023. Prosthetic work with Brevis housing. Conditioning the oral cavity. The second case, the work presents a prosthetic reconstruction on telescopes of a seventy year old patient, also a lady, Stage one February twenty twenty, implantation of Bicon implants in location twenty four and twenty five. Stage two June 2020, implantation of Bicon implants in location eleven, fourteen and sixteen. Delivery of work in January 2021. In location twenty four, the bone got completely crushed. The implant was covered with bone and left at the patient’s request. CBCT follow-up on consultation in March 2025. Interval in surgical stages waiting for implant healing at location twenty four. Location sixteen, Bicon implant four point zero by five point zero. Date of implantation, June ninth 2020. Location fourteen, implant four point zero by six point zero, date of implantation June ninth 2020. Location eleven, Bicon implant three point zero by six point zero, date of implantation June ninth 2020. Location twenty five, Bicon implant four point zero by six point zero. Date of implantation, February nineteenth 2020. And this is a clue of this location twenty four, Bicon implant four point zero by six point zero. Date of implantation February nineteenth, 2020. Controlled CBCT taken five years after the procedure, implant healed with full stabilization. And what happened here? It’s not of skills of surgeon, because those very bad surgeon, but it’s skills of Bicon implant. Condition in oral cavity. Prosthetic work with view elements in the work galvanized with gold and prosthetic laboratory president. View of their work in the other cavity. The cases of the last two patients demonstrate proper implant healing despite very difficult condition and lack of bone. In our opinion, the success is possible due to the unique feature of Bicon implants resulting from the lack of primary stability. I also I would like to acknowledge my teachers, Dr. Katarzyna Maciejewska and Prof. Mauro Marincola. I would like to send thanks to team of my clinic, part of them are today with me, Dr. Luisa Mihalska Rataji, Lewandowski Poknitska. And I would also like to thank my wife. Without her, my professional success wouldn’t be possible.
