Implantology and SLA Surface

IMPLANTOLOGY

Implantology has become a natural part of dental treatment. On one hand, extensive research and development, and on the other, the comprehensive expertise of dentists and dental technicians, have made the installation of implants a routine practice today. The foundation of the OPUS implant system is based on this robust structure. In close communication with experts from clinics and dental offices, it has combined proven ideas with innovative solutions while considering future demands.

Dental implants placed in the jawbone function as tooth roots. Since they possess characteristics closest to natural teeth, they provide better chewing and speaking functions compared to bridges and traditional prostheses. They also offer a more natural and aesthetic appearance. Successful results can be achieved when correct and sufficient knowledge, experience, and equipment are combined. With proper care, dental implants can be used for many years. The patient’s existing bone condition and systemic diseases are very important for implants. With the latest technology, most patients are made suitable for implant treatment. The OPUS Implant System contains minimum components with maximum flexibility. It can be used for all indications and in all positions within the mouth. Your trust in us is based on scientific evidence. Therefore, since our establishment, OPUS's research teams have collaborated closely with leading clinics, research institutes, and universities to provide validity for our products, which meet exceptional quality standards.

Tooth loss is a very common problem; therefore, the use of dental implants has also become a common practice. Research into dental implant designs, materials, and techniques has increased in recent years and is expected to expand in the future. However, much work remains to be done on better biomaterials, implant design, surface modification, and functionalization of surfaces.

We offer high-quality implant systems with diameters ranging from 3.4 to 4.8 mm and lengths of 8, 10, 12, and 14 mm. All our implants are made of titanium alloy Ti-Grade4 and comply with ISO5832-2 standards. Titanium has the property of fully integrating into the bone. When combined with the partial advantages of strength and durability, titanium becomes the ideal implant material. The flawless internal structure of the OPUS Implant System ensures an exact fit between the abutment and implant, preventing micro gaps. This ensures the implant’s longevity and prevents screw breakage or loosening.

IMPLANT SURFACE

The rate and quality of osseointegration of dental implants are related to surface roughness and composition. Today, titanium and titanium alloys are considered the best materials for bone connection. Various surface treatments are applied to titanium implants to further enhance their biological acceptability. The primary aim of these surface treatments is to adapt to surface topography and surface energy. In this way, wettability, cell proliferation, cell growth, and bone apposition increase, thereby accelerating the osseointegration process. The osseointegration process occurs in two stages. In the first stage, the placed implant material comes into direct contact with the bone. At this stage, there is no supportive structure between the bone and the organic structure. During this initial period, which lasts until the formation of the biological structure, the interaction between the implant and its surroundings is mainly mechanical due to the lack of a supportive structure. In the second stage, observed in studies on the osseointegration process, the titanium implant in contact with the bone is covered with soft fibrous tissue. It is critical for this capsule structure surrounding the dental implant to have the correct thickness and structure to bear the loads applied to the dental implant and to stabilize it adequately in the bone. These two stages are vital for preventing implant loss and ensuring the long-term performance of the implant. For SLA surfaces, the osseointegration period lasts between 6 to 8 weeks.

In surface preparation methods, SLA (Sand-Blasted Anodizing) surfaces are used. SLA surface coating is not an overlay. Sandblasting is applied to roughen the surface.

The entire interior and surface of the implant undergo uniform sandblasting. Following the sandblasting process, acid etching at high temperatures is applied. As a result, small micro-pores measuring 2-2.5 microns are observed on the implant surface. This unique macro/micro topography reduces the possibility of bacterial colonization while providing an ideal structure for cell attachment. SLA implant surfaces are moderately rough surfaces. The degree of roughness is consistent across the implant surface. The SLA system is the surface treatment system that provides the highest success rate in healing.
