LASAK company founded by doc. Ing. Zdenek Strnad, CSc,. and Ing. Igor Riedl, CSc. more…
The establishment of the LASAK company was preceded by cooperation in research and development at the Sklo Union Research Institute, as well as cooperation with a number of Czech and foreign institutions, in the field of researching new materials for artificial tissue and organ replacements.
After the closure of the Sklo Union Research Institute, at the beginning of the 1990s, doc. Ing. Zdenek Strnad, CSc., together with Ing. Igor Riedl, CSc., motivated by previous successful research, decided to create a new centre where it would be possible to continue researching these advanced materials. Towards the end of 1991, they founded the LASAK company with its headquarters in Prague, where not only research, but also the realization of these promising materials was successfully achieved.
Doc. Ing. Zdenek Strnad, CSc.
Graduated from the University of Chemistry and Technology Prague in 1962, where he successfully defended his doctoral dissertation on silicates. He habilitated there as an Associate Professor in 1992. From 1970 to 1971, he worked as an independent researcher at a number of universities in Great Britain. In 1986, he was employed by the Nippon Electric Glass Ltd., in Japan, as a consultant for glass ceramic materials. Prior to this, he had worked at the Sklo Union Research Institute for nearly 20 years (1974–92).
Ing. Igor Riedl, CSc.
Graduated from the University of Chemistry and Technology Prague in 1958 and was later awarded a postgraduate degree, “Candidate of Sciences” (CSc.). After he graduated, he became a technologist in the then national enterprise, "Prumyslove sklo" (Industrial Glass), at its “Ruzenin” plant. Later, he became a researcher in the Technical Glass Research Institute, in Prague, where he became a research group manager in 1968. He worked in research until 1990 when he was nominated Deputy Minister of Industry of the Czechoslovak Republic.
The first implant system of the LASAK company, IMPLADENT, was launched on the market. more…
The IMPLADENT implant system is gradually being recognized worldwide, with all technical details complying with the international consensus on material and design requirements for osseointegrated implants, i.e. implants inserted in the bone without any soft tissue interlayer, which can be considered a fundamental feature of contemporary dental implantology. At the time of its launch, dental implants were sandblasted and coated with bioactive hydroxyapatite. This type of surface was characterized by high osseoconduction properties and extreme tolerance of unfavourable conditions of osseointegration. Since 2000, after lauching LASAK´s new unique, hydrophilic, nanostructured, bioactive surface (BIO-surface), IMPLADENT implants are treated with this surface, thus significantly enhancing their properties.
Over the years, the IMPLADENT implant system has continued developing and improving, and has been complemented with new components.
BAS-0, BAS-R, BAS-HA
In the same year, LASAK also launched synthetic replacements for bone tissue based on glass ceramics and ceramics. more…
There are three kinds of bioactive materials with different characteristics and application possibilities:
BAS-0 – Apatite-wollastonite containing bioactive glass ceramic
BAS-R – Resorbable, tricalcium-phosphate-based ceramics
BAS-HA – Hydroxyapatite-based ceramics
Since these fully synthetic materials did not contain any organic elements, there was zero risk of immune reactions or transmission of pathogens.
These bioactive materials were then used for the fabrication of individual implants for facial surgery, such as orbital implants, ear or nose bone prostheses or fusion prostheses of intervertebral discs.
Introduction of an innovative synthetic tricalcium-phosphate-based material for bone regeneration. more…
Maximum effort and intensive investment in regular research and development facilitated the creation and introduction of a new bone graft product, PORESORB-TCP. It is a fully synthetic, tricalcium-phosphate-based material for bone regeneration. Thanks to its macro- and microporous characteristics, the structure of PORESORB-TCP is very similar to bone structure. As a bioactive, resorbable, inorganic, crystalline, non-metallic bone regeneration material, PORESORB-TCP has gained a good reputation, not only in dental implantology but also in neurosurgery and orthopaedics.
The LASAK company was one of the first implant manufacturers to produce narrow-diameter implants with a diameter of only 2.9 mm. By 2006, as the first implant manufacturer on the European market, the company was already able to present a nine-year clinical study with excellent results. more…
The IMPLADENT implant system was complemented with a narrow range of dental implants and corresponding prosthetic, impression and laboratory components. This innovation led to widening the application possibilities of treatment to also include cases where implants had been so far problematic or impossible to use; most frequently in the anterior area with reduced bone or with little space between the teeth or the implants.
The product portfolio was widened with intervertebral disc replacements. more…
The excellent osseoconductive properties of new titanium materials, that lead to faster and improved healing of IMPLADENT dental implants, made it possible to extend the application of these materials into neurosurgery. In addition to dental implants, LASAK started producing intervertebral disc replacements, which prevent instability of the affected motion segment of the lumbar or cervical spine.
The successful development of a breakthrough technology of titanium surface treatment. LASAK was the first company to launch a bioactive, hydrophilic, nanostructured surface treatment of dental implants (BIO-surface) on the European market. more…
The LASAK company, led by Ing. Jakub Strnad, Ph.D., developed an original surface treatment technology creating a three-dimensional macro-, micro- and nanostructured hydrophilic titanium surface with bioactive properties, known as BIO-surface. Well-documented clinical and trial results confirmed that dental implants with the BIO-surface significantly speed up and improve the osseointegration process. They also optimise implant stability in the critical primary healing stage, which leads to higher predictability and an improved treatment success rate and allows the application of new progressive clinical methods that significantly reduce treatment time.
The BIO-surface stimulates the establishment of osteogenic cells, assists their differentiation and the bone matrix synthesis, which leads to the creation of a deeper bone-implant contact in less time and without any soft tissue interlayer. Leading world manufac¬turers soon also adopted this type of implant surface treatment.
Appointment of a new CEO
The LASAK company owners appointed Ing. Jakub Strnad, Ph.D,. as the new managing director during the annual meeting. more…
Ing. Jakub Strnad, Ph.D., had worked in the company since 1998 starting as a researcher and passing through all the key company processes across different levels of management. His expertise, international experience and personal characteristics, together with the active support of the company's partners, have contributed to the continuous growth of the company.
Introduction of a synthetic bone regeneration material based on hydroxyapatite with a low substitution rate. more…
The OssaBase-HA regeneration material presented a chemically and structurally similar, synthetic alternative to biological bone substitutes. Its fully synthetic composition guarantees zero risk of immune reactions or transmission of pathogens. The system of interconnected macro- and nanopores, which mimic the structure of human bone, offers a perfect substitute for missing or lost bone tissue independently, or in combination with, autologous bone tissue.
The LASAK company was awarded the prestigious Czech Scientific Award, “Ceska Hlava 2010” in the category Industry Award for Innovation in a Dental Implant System. more…
The innovation included the unique bioactive surface treatment and innovative implant design which enable high primary stability, and faster and safer healing of the implant in the bone tissue. LASAK was the first company to launch a bioactive, hydrophilic, nanostructured surface treatment of dental implants (BIO-surface) on the European market.

Moreover, the Research Centre hosts implantology training and lectures for dentists and dental technicians from the Czech Republic and abroad.
The LASAK company launches a unique production system of precisely milled CAD/CAM dental constructions for implants. more…
LASAK CadCam technology offers the fabrication of precisely milled prosthetic constructions fixed directly to the implants without the need for abutments or any other attachments. This reduces the number of interfaces between the implant and the prosthesis, which could present potential sources of bacterial contamination.
The LASAK company started producing individual artificial replacements for the anatomical reconstruction of bone defects in the cranial and facial area. more…
These are unique, individual implants designed and fabricated exactly according to the CT data of each patient. The borders of the replacement match perfectly the borders of the defect, which guarantees an excellent aesthetic result without the need to adjust the implant in the operating room.
Based on 20 years of experience in manufacturing dental implants, a new implant system was launched. more…
