SGS Dental implants: Perfect biocompatibility, lifetime guarantee

SGS Dental products entered markets in Russia in 2011. And last year, in 2020, received a market authorization for the company's groundbreaking implant range. What are the features and benefits of the new SGS Dental implants?

SGS International Ltd. was founded in the region of Shaan in the Principality of Liechtenstein in 2007. A few years later, as part of an expansion of production, implant manufacturing was moved to Budapest, the capital of Hungary. SGS Dental's innovative SBTC coating is processed in Germany — at the DOT factory, which has one of the most advanced laboratories in the world.

SGS Dental products are in the mid-range price segment, although they are of comparable quality to premium brands such as Straumann, Astra Tech, etc.

Swiss equipment, the use of titanium oxide in the creation of the implant, innovative coating, and a wide range of prosthetics all contribute to the price. But it helps dentists solve almost any clinical problem, and patients to lead a fulfilling life with a big smile.

The new SGS range includes different types of implants and their superstructures — our own range of abutments and multi-units, etc. All prosthetic components and instruments are colored gold to prevent any confusion with the superstructure of the classic SGS implant lines.

TYPES OF IMPLANTS:

• P1D, for dense bone types (D1, D2). The implant has a very fine thread pitch. This allows it to enter the bone gently, without injuring it.
• P7D, for loose bone types (D3, D4). Aggressive implant, with a wide thread, which provides better adhesion to loose bone.
• The P5D is a universal implant, for all bone types. NEW! It is an implant with a unique «Matrix» thread developed by SGS.

All implants are suitable for immediate loading protocols and single-step implantation. Provide high primary stabilization.

HOW IS AN SGS IMPLANT CREATED?

The future implant is cut from a five-meter-long medical grade titanium bar on a machine.

Next, it needs to have a porous structure, and to achieve this, the implant is sandblasted with titanium oxide. This is the difference between SGS and other, cheaper systems in which the implants are treated with aluminium dioxide.

After processing, the implants are acid-etched — they are dipped in a bath of acid and metal particles must be washed out. But micro-particles of aluminium can remain in the body of the implant and subsequently poison the patient's body. This is why aluminium is not used in the processing of SGS implants.

The implant is then coated with SBTC and then sent for gamma irradiation sterilization and sealed in sterile conditions. 

STUDY OF THE OSSEOINTEGRATION OF PT-COATED TEST IMPLANTS AND PT/BONIT®-COATED IMPLANTS

COATING: SBTC

Another key difference with SGS Dental is the Smart Bioactive Trebecular Coating (SBTC). Most implant manufacturers do not use coatings at all, limiting themselves to sandblasting and acid etching.

Some implant systems are coated as follows: calcium phosphate is sprayed onto the implant body: by plasma spraying. A 200–300−micron thick calcium «coat» builds up on it. This thick coating is heterogeneous, which can cause it to peel away from the implant during insertion. It is also prone to the formation of calcium lumps, which leads to the formation of a fibrin coating. Even if the surgeon performs the operation perfectly, the implant may begin to loosen, unscrew, and disintegrate after a few years. Such cases are not exceptional.

SGS Dental implants have a thin — 10−20 micron — bioactive calcium-phosphate coating SBTC, which is applied by electrochemical deposition (immersion in a special solution bath). The chemical composition of the coating is a mixture of bruchite (a readily soluble phase of calcium phosphate) and hydroxyapatite. The good thing about that is that it interacts with the body significantly faster: it has time to «attract» osteoblasts, increasing the rate of bone formation on the implant surface. After all, it is not enough for the implant to be mechanically well anchored in the bone. It is necessary for it to «fuse» with the bone tissue. It is in such cases that a lifetime guarantee can be given for its installation.

CONNECTION: CONE

The classic implant system has a flat connection — the inner hex. But practicing dentists have proven that implants with another type of connection, the tapered type, perform better in various clinical situations.

Studies have confirmed that with the classic joint type, there is micro-mobility, especially in the masticatory group of teeth. When the patient chews, the implant moves, although this mobility is measured in microns. Accordingly, a vacuum is created between the abutment and the walls of the implant, which acts like a pump, drawing in all unfavorable flora, food particles. This can cause resorption and rejection of the implant. Therefore, the patient has to see the doctor every six months to have the structure taken apart and cleaned.

In the case of tapered implants, this micro-mobility is almost non-existent  — due to the cold-welding effect, unfavorable flora does not penetrate the implant and cleaning every six months is not necessary for these implants.

Based on its own research, SGS Dental has decided to launch a new range of implants with an 8−degree taper, but to keep the classic range in production to ensure it remains the preferred choice of doctors.

CONE: 8 DEGREES

The implant systems available today have a different cone angle. To achieve a cold-welded effect, manufacturers use a more or less radical cone. The developers of SGS have studied this question at length and have concluded that 8 degrees is the most optimal angle for both the doctor's work and the long-term preservation of the cold-welding effect.

WIDE RANGE OF SUPERSTRUCTURES

SGS Dental is one of the few implant systems that has a wide range of superstructure types and sizes — from gingiva shapers, transfers, angled abutments to 45−degree multi-units. This enables orthopedists to deal with any clinical situation, even the most complex.

SURGICAL KIT

SGS Dental has taken a holistic approach to surgical kit formation. The SGS basic surgical kit includes tools not only for surgery, but also for orthopedics: various screwdrivers (short and long), wrenches, and even a torque wrench (rather than the usual reversible wrench).

The specialist receives tools for working with all SGS Dental implant lines: universal cutters, implant guides for hex, taper, narrow taper.

The premium level of the entire SGS Dental system is due to European production under the supervision of a Swiss office and engineers, high-precision Swiss equipment and expensive raw materials. All this ensures the consistently high quality of the SGS Dental system.

Peri-implantitis. Laser. Waterlase

The laser came to Russian dentistry in the early 2000s and today is no longer perceived as something revolutionary. It has become the standard for quality dental care, for which there are proven protocols and methods. Today we are talking about the protocol for the treatment of peri-implantitis.

Our call is very important to you

As you know, the greatest business benefit comes from a patient who does not leave you forever. Successful clinics earn up to 80% of their revenue on return visits. The base of repeat patients is a huge resource, and experts say that millions are buried in it, but is it so easy to dig them up?

BrainMark Dental Studio: Great Start

The chain of family dental clinics BrainMark Dental Studio from the UNIDENT group of companies was launched in Moscow just over a year ago, under conditions of restrictions and quarantine measures. And in just a year, all four centers of the chain achieved results that some clinics have been going for decades.
