The 18th implantology seminar IMPLANTOLOGY 2014 took place on 4 April 2014. Among the participants were nearly 200 dentists and dental technicians dedicated to implantology from the Czech Republic and abroad.
It has become a tradition that the seminar was inaugurated by Jakub Strnad, CEO of LASAK, followed by Prof. Dr. Jiri Mazanek, moderator of the first lecture session.
An introductory lecture by Dr. Dana Kopecka (Hradec Kralove, CZ) dealt with practical assessment of the quality of the bone suitable for implant placement, various defects and adjacent anatomical structures, based on long-term experience. She addressed the choice of length, width and possible use of tilted implants. The presentation was accompanied by a series of illustrative X-ray images and CT scans. She also discussed the suitability of applying different diagnostic methods for important anatomical structure detection.
Tilted implants were also the subject of the presentation given by Dr. Antonin Simunek (Hradec Kralove, CZ). The performance of a final element analysis showed the stress distribution in the bone surrounding such implants, which can be placed in an area of higher quality bone, while the implant neck can be placed in a more convenient area from the prosthetic point of view. These theoretical assumptions together with presented clinical experience invite further investigation and evaluation of the results and offer a good prognosis in the case of this type of implant.
Solutions for edentulous jaws were the general subject of the lecture given by Chief Physician Dr. Ladislav Dzan (Liberec, CZ) that presented the advantages and disadvantages of the so-called social solution – restorations anchored on two implants with ball attachments − with the support of thirty-six case studies. The solution for the edentulous jaw is on one side a great challenge for any implantologist, yet on the other side, it can become their nightmare.
Based on rich long-term experience in periodontics and implantology, Dr. Curd M. L. Bollen (NL) gave an interesting presentation oninflammation of soft tissue surrounding the implant and on peri-implantitis accompanied by resorption of bone tissue. Dr. Bollen presented basic statistical data regarding peri-implantitis, carried out defect classification according to its dimensions, and presented aetiological factors for peri-implantitis. In the second part of the lecture, he presented the main non-invasive and surgical treatment methods and demonstrated their effectiveness by means of his own clinical cases, accompanied by abundant photographic documentation. Dr. Bollen’s contribution was met with extraordinary acceptance and invited a lively discussion.
Dr. Tomas Siebert (SK) introduced the complex procedure of immediate implant placement and functional loading in a patient treatment using the LASAK Impladent system. This treatment method aims at maximizing the patient’s comfort by cutting out the edentulous phase. The strategy for choosing the conservative approach, periodontal treatment and implant placement was also discussed.
Prof. Dr. Tatana Dostalova (Prague, CZ), delivered a stimulating speech on CAD/CAM technology for production of dental implants out of homogeneous BioCam system units. Progressive research makes the production of such implants less costly and improves their precision. This solution literally opens doors to perfect aesthetics and high reliability. What catches one’s attention is the experience with creating pseudo-papillae, which contribute to impeccable aesthetics.
Associate Professor Dr. Pavel Polenik (Pilsen, CZ) concluded the seminar by delivering a lecture on interaction of connective tissue with the hydrophilic, bioactive surface of implants. Soft tissue surrounding the implant is an important element which constitutes the interface between the osseointegrated part of an implant and the microbially contaminated oral environment. It plays an essential role in prevention of infections threatening the implant service life. The most convenient solution seems to be the achievement of an interface between the soft tissue and the implant that most closely resembles the physiological attachment from both the structural and the functional point of view.
The poster section presented clinical studies of maxilla reconstruction, results of experimental development and a study evaluating the key properties of dental implants − comparison of the bioactivity and fatigue stress limit of dental implants available in the Czech Republic − and the bioactivation of titanium and PEEK. The visitors were free to ask questions concerning the new system BioniQ® and BioCam® bridges and abutments on display in the lobby, as well as to make other enquiries to the R&D and sales representatives from LASAK.
