The 16th annual scientific implantology seminar was organized by the company LASAK on 20 April 2012 at the Clarion Congress Hotel Prague. The seminar was attended by nearly 200 dentists and dental technicians from the Czech Republic and abroad.
Jakub Strnad, PhD, director of LASAK, opened the seminar and welcomed the participants. He was followed by Prof. Jiří Mazánek, MD, DS, as moderator for the morning lecture blocks. 
The introductory lecture by Prof. Antonín Šimůnek, MD, PhD and Dana Kopecká, MD, PhD from Hradec Králové was focused on the immediate loading of implants as a reliable procedure for tooth replacement. This procedure, which has increasingly been in demand, was made possible in particular by the highly structured implant surfaces that accelerate osseointegration and by the conical shape of the fixtures that facilitate the achievement of high primary stability. The authors discussed in which cases, under which circumstances, and by which technique this method can be used. By default, it is used for ACCEL and ProImplant, IMPLADENT implants, which was demonstrated by many case reports. The lecture was accompanied by a video demonstration of the operation.
Dr. Jiří Holakovský from Prague demonstrated the reconstruction and rehabilitation of the defect after comminuted mandibular body fracture and loss of the mandibular alveolar process, including teeth, on a specific female patient. The alveolar bone distraction technique was used in combination with horizontal alveolar ridge augmentation to deal with the lack of vertical volume. Intraosseous dental implants were inserted after healing.
In modern implantology, there has been a growing need for the replacement of insufficient alveolar bone volume. Dr. Miguel Lecaro David Cevallos, PhD, from Hradec Králové presented clinical results, supported by histological evaluation of biopsies, of the specific combination of β-tricalcium phosphate and autologous bone as augmentation material for a two-stage lateral sinus lift.
Dr. Thomas Vosáhlo from Hradec Králové presented several case reports as examples of implant-prosthetic reconstructions with different treatment concepts. They are designed based on anatomical features of the alveolar bone, vertical distance of the jaw relationships, presence of parafunctions, or with respect to the types of previously implanted prosthetic works. To achieve the most natural result, the implant-prosthetic treatment itself is often preceded by periodontal or orthodontic pretreatment.
Using examples from his own dental practice, Dr. Ján Gazdačko from Martin, Slovak Republic, presented several types of implantology treatment in patients with various complications (hepatitis, osteoporosis, type 2 diabetes, and others). Given the overall health of the patients and their financial means, he selected hybrid replacement in most cases. In the conclusion, he described the case of a nurse who had contracted jaundice from a patient, and experienced severe calcium deficiency as a side effect of the therapeutic substance. After stabilization, implants were placed in the patient 19 years ago and are still functional to the patient’s satisfaction until today.
Dr. Rudolf Hocheneder from Munich, Germany, presented on “Periimplantitis: a predictable therapy, combining photodynamic therapy (Helbo-Laser), soft tissue graft and PRP.” With the increasing number of implants, more and more problems with periodontal diseases can be seen around the implants (mucositis, periimplantitis). Compared to conventional periodontology, the implant-bone interface differs substantially from the natural teeth, and therefore different diagnostic and therapeutic schemes are needed. Dr. Hocheneder introduced a proven concept of solutions for peri-implant infections and demonstrated the surgical procedure step by step.
The lecture of Assoc. Prof. Dr. Pavel Poleník, PhD, from Plzeň, was focused on the current issue of the integration of soft tissue with the implant surface. Soft tissue surrounding the implant is an important element forming the interface between the implant and the osseointegrated, microbially contaminated environment of the oral cavity. Results of the tests showed that the character of the titanium surface is an important factor that governs the development and quality of the connection with type I collagen fibrils.
The conference also included a poster section, which presented the use of the customized abutment Cast-On, which was introduced on the Czech market by LASAK during the spring.
