Company history


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.

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.

Temporary ProImplant implants

The ProImplant system was developed with the aim of increasing treatment aesthetics and comfort for patients. More


LASAK one-piece temporary ProImplant implants enable the temporary treatment of patients with high aesthetic and functional demands with an existing prosthesis or with provisional fixed dentures during the healing period for permanent implants or graft sites. These temporary ProImplant implants give your patients the opportunity to leave your practice immediately after implantation with a functional denture.


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 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.

Based on 20 years of experience in manufacturing dental implants, a new implant system was launched. More


Thanks to LASAK’s proprietary long-term research and development, a new system BioniQ® was launched, which offers a unique set of properties while remaining simple and cost-effective.

Development of BioniQ implant system



BioniQ S2.9 narrow implants

LASAK adds narrow S2.9 implants and a new QN prosthetic platform to the BioniQ® implant system. More


S2.9 implants are made of high-strength titanium and feature the hydrophilic, nanostructured BIO-surface – the same as other BioniQ implants. The BioniQ® system offers an optimal solution in cases where treatment with conventional dental implants is either problematic or completely impossible; most frequently in the anterior area with reduced bone or with little space between the teeth or the implants.


BioniQ Plus implant

LASAK has extended its BioniQ implant system with BioniQ Plus implants with a machined collar, which are intended to be inserted, primarily, into the distal area. More


The BioniQ Plus implant has a machined collar with a height of 1.7 mm. It is fully compatible with all the instruments for BioniQ implants and the prosthetic components of the QR and QN platforms. The intraosseous part of the implant is provided with a BIO-surface, which ensures the excellent osseointegration that is a characteristic of all the BioniQ system implants.


Guided surgery

In the digital implantology, LASAK offers solutions and services for both pilot guided and fully guided surgery using the BioniQ implant system. More


BioniQ fully guided surgery is intended for prosthetics driven treatment with BioniQ implants inserted at the level of the bone using a surgical template. A surgical template printed on a 3D printer guides all instruments in precise trajectories. The surgical guide is equipped with titanium sleeves with tool stops to achieve the desired osteotomy depth and to ensure the accurate prosthetics position of implant according to the pre-prepared plan.


Fully guided surgery for edentulous jaws

BioniQ fully guided surgery also allows the management of prostheses for individual treatment of edentulous and partially edentulous jaws. More


This advanced solution allows the surgical template to be precisely anchored even in the most challenging anatomical conditions. The stability of the surgical template is essential if the surgical treatment is to be accurate from start to finish. This is particularly important when placing the template on the gingiva of an edentulous jaw, as this is where the greatest inaccuracies may occur. BioniQ fully guided surgery will ensure that the surgical template remains in a stable position during the entire surgical procedure, thus allowing the dental implants to be inserted safely and accurately into the planned location.
