Quality and rating of German dental implants from Alpha Dent Implants

Alpha Dent Implants company (Germany)

The company's employees developed a bone-implant system and were able to achieve predictable osseointegration of structures, significantly reducing the risks of unsuccessful implantation. Implants undergo thorough quality control and meet international standards ISO 9001, ISO 13485.

Alpha Dent Implants participates in charity events and conducts training courses for beginners and experienced dentists. The company's philosophy is that high-quality implantation can be accessible to everyone . The company has representative offices in different countries.

Features of the technology

• Surface 3D . Based on research conducted by the STR Surface Research Treatment laboratory (UK), a bioactive 3D surface for implants was created, which became the main achievement of the company. The coating has a porous multi-level structure obtained by sandblasting with oxide microparticles. This has a beneficial effect on the speed of healing of the structure.
• Oxide film is a coating of calcium hydroxyapatite, 10-12 microns thick. Stimulates active growth of bone cells and protects the surface of the implant.
• Biocompatible material . The gum formers, abutments and the implants themselves are made of pure titanium alloy GRADE 4. It combines high strength and biological compatibility with jaw tissue, which prevents allergic reactions and minimizes the risk of rejection.
• Carving . Each type of implant is threaded to allow installation with minimal damage to the bone. By choosing one or another option, you can achieve maximum compression, since when screwing the products, the bone tissue around is compacted, creating a kind of shell.

Alpha Dent implants can be installed in loose, narrow bone, with a minimum amount of tissue.

Types of thread of implants for Alpha Dent teeth

The lower part of the structure (intraosseous) is manufactured in three versions, due to which implants are divided into:

1. Screw - have a pointed thread, which is responsible for reliable fixation in the gum. They are screwed in according to the principle of a self-tapping screw.
2. Conical - imitate the anatomical shape of the tooth root. This is an innovative development with a 3D surface.
3. Cylindrical - shaped like a cylinder with a thread on the end. The surface also has a porous structure that accelerates fusion with the bone.

There are models for immediate and delayed loading, as well as for implantation in conditions of significant atrophy of the jaw bone.

Alpha Bio implants: reviews

On Alpha bio implants – reviews from implantologists are in most cases positive, but this should not mislead you.
This economical option is offered to patients with a limited budget, and so that the patient does not refuse implantation at all, he is not told about some of the disadvantages of this option. Of course, if we are talking about implantation in the area of ​​the front tooth (in an area with a lack of bone volume), then it is best to choose the more expensive Straumann, Nobel-Biocare or Astra implants. And if you also have a gummy type of smile (the gums are exposed when you smile), this is generally critically important. But if implants from these manufacturers are too expensive for you, there are 2 more alternatives. For example, the Israeli company MIS also has 3 implant options with an ultra-hydrophilic surface. Another economical option may be to install the TS-III CA implant from the Korean company Osstem (this implant also has a modern surface with increased hydrophilicity), but it is best used only on the upper jaw.

But as for the implants themselves, its best products are the NEO and SPI model implants. Below we will give several examples of the use of implants of this brand in practice...

1) Clinical case – absence of 4-5 teeth. A one-stage implantation technique was performed using 1 AlphaBio implant. Based on the implant and the patient’s own 6th tooth, a metal-ceramic bridge of three crowns was installed (note that a slight cyanosis of the gums around the crown on the implant is immediately visible).

2) Clinical case - with a complete absence of teeth in the upper jaw, 6 AlfaBio implants were implanted (two-stage implantation technique), onto which a permanent metal-ceramic bridge prosthesis was fixed after 6 months.

3) Clinical case – absence of a central incisor in the upper jaw. A two-stage implantation technique was performed, complicated by a lack of bone tissue in the area of ​​the missing tooth. In parallel with the installation of the implant, bone augmentation was carried out using bone material and a bioresorbable membrane.

Commentary on this clinical case - let's look carefully at Fig. 22... despite the bone grafting performed, we see that the alveolar process in the area of ​​​​the installed implant has a large concavity. Those. the increase in bone volume occurred in insufficient volume, and here the anterior bone wall will be clearly thinner than 2 mm. Of course, this will lead to bone tissue atrophy on the front surface of the implant, gum recession, and poor aesthetics.

In principle, in Fig. 23-24 we already see that the volume of the gingival papillae is insufficient, and due to this, the interdental spaces look like dark spots (dips). Over time, this problem will only worsen and the aesthetics will become completely unacceptable. That’s why we say that Alpha-Bio implants are not a very good option in the area of ​​the front teeth (especially if there is insufficient bone volume).

Summary:

If the protocol for the surgical stage of implantation is followed, the survival rate of Alpha Bio implants is about 96% when implanted in the upper jaw and about 98% when implanted in the lower jaw. These are good indicators, but not the best. Again, for market leading companies these figures are still 1-1.5% higher. However, as we said above, implant survival is not the only indicator that you need to pay attention to.

For example, the main reason for negative reviews of implants is the increasing deterioration of aesthetics in the gingival zone. This is due to the natural gradual atrophy of the bone around the implant neck, which can reach up to 1.5 mm only during the first 1.5 years. A decrease in the bone level leads to the fact that the neck of the implant remains covered only by the mucous membrane, which leads to the appearance of sharp blueness of the gums around the implant, as well as a decrease in the level of gingival papillae. Therefore, a very important criterion when choosing an implant in the aesthetic zone is the amount of bone atrophy during the first 5 years.

And clinical studies and the experience of implantologists can give us an idea of ​​this. When implanting in the aesthetic zone (in the area of ​​the front teeth), I would give preference primarily to AstraTech and Straumann implants, because these implants have the lowest rate of bone atrophy. As for the implantation technique with immediate or early loading, when prosthetics are carried out immediately or within several weeks after implantation, then it is also advisable to choose the above implants (but if the budget does not allow, then at least MIS or Osstem).

What is included in the implant system catalog

• Gum formers;
• abutments;
• implants;
• transfers;
• locators.

In addition to dental systems, the company offers: dental cement, drills, implant drivers, and instruments. For the convenience of specialists, the latter are formed into sets: compression, surgical, for sinus lifting and others.

Types of implants

1. Active - rods with active triple thread in the form of a spiral. They have an increased area of ​​contact with the bone and increased stability. Used for immediate installation in soft or damaged bone.
2. Classic is a root-shaped implant, made in a classic shape, with a triangular thread. Can only be used if there is sufficient bone tissue in a healthy state.
3. Active Plus - has a cone shape with a small thread at the top. Prevents bone resorption and relieves stress on it.
4. Active Conus is an analogue of the Active model, which additionally provides strong adhesion to the abutment.
5. Classic Conus is a cone-shaped product that connects to the abutment and healing abutment. This allows the crown to be firmly secured.
6. Slim is a thin implant for fixation in a narrow bone (frontal zone). It can be installed in the alveolar ridge or between closely spaced teeth. Suitable for immediate loading.
7. Integral is a monolithic abutment design with high primary stability. It has several levels of thread height, rounding in the apical zone and micro-threads in the area of ​​​​contact with the cortical plate of the bone. Indicated for installation in atrophied and soft bone. Designed for one-stage implantation in a minimally invasive manner, does not require a gum incision.
8. The company's latest development is the Active Bio with a hydrophilic 3D surface. It is distinguished by a triangular body shape in the area of ​​​​the transition of the cortical bone to the spongy bone, which provides maximum anti-rotation effect and the creation of favorable conditions for bone regeneration. To increase primary stability, a “latch effect” is used.

Abutments

Alpha Dent Implants custom abutments:

• spherical;
• conical (angular, straight, wide);
• zirconium;
• plastic and aesthetic superstructures;
• titanium (long, wide, narrow, angular, straight, with or without ledges);
• plastic burnt out;
• temporary (made of biologically compatible thermoplastic).

Thanks to their diversity, they give the dentist the opportunity to achieve good aesthetic results in any clinical case. They are easy to combine with implants of any type, adjusting the prosthesis to the patient’s dentition. Each abutment is equipped with a screw for attachment to the implant. All elements are divided by color for easy selection.

Dentium implants

A high-tech product from a South Korean manufacturer. There is a premium and budget line of Dentium implants.

All Dentium series, according to experts, are characterized by:

• Root-like shape close to natural. The pin is located in the hole and evenly distributes the load on the bone. The original thread of Dentium implants contributes to the rapid stabilization of models.
• Hermetically connects to different types of abutments.
• The increased area of ​​contact with tissue accelerates implant healing.

There is a line of mini-implants, the installation of which is minimally invasive; the designs are suitable for installing “all-on-4” or “all-on-6” systems. Dentium brand implants take root in 99% of clinical cases and are used for express implantation (installation at the time of removal). The brand produces several size ranges, so it is easy to choose the right model for each patient.

Product advantages

The Alpha Dent Implants dental system is characterized by well-thought-out packaging, convenient color coding and beautiful design. Among the main positive points:

• the ability to install several rods immediately after tooth extraction;
• rapid period of osseointegration;
• high probability of engraftment (98%);
• preventing tissue damage during installation;
• correct distribution of chewing load on the jaw;
• minimal risk of allergic reactions or rejection;
• use of pure titanium;
• active thread for reliable fixation in the bone;
• 3D Active coating, which enhances the adhesion of implants to bone tissue cells;
• ease of use (does not require complex hygiene procedures);
• high strength;
• lifetime warranty.

Installation process

Installation of Alpha Dent products can take place in one or two stages, depending on the specific model.

Single-stage technology has recently become the most popular. Installation takes place in an outpatient clinic, and the entire process takes less than an hour. One-stage implantation is performed during one visit to the dentist.

Initially, at the site of the missing tooth, the doctor expands the root canal, into which the structure is then installed. The head of the implant extends beyond the edges of the gum, so a temporary crown can be installed on the same day.

Thanks to this approach, it becomes possible to immediately restore the aesthetic appearance of teeth and restore their functionality.

Engraftment of the implant takes from three months to six months. As soon as this happens, a permanent crown is installed in place of the temporary one.

Two-stage implantation got its name not by chance and it proceeds as follows:

• Initially, the implant is implanted into the bone tissue;
• After the structure has healed, an abutment is installed.

Alpha Dent products are characterized by a long service life, which ranges from 15 to 25 years. If the prosthesis is damaged or broken, then specialists can easily and quickly restore it under warranty.

Manufacturer's warranty

The manufacturer provides a lifetime warranty on Alpha Dent implants . All elements undergo a multi-level control system. To protect against counterfeiting, the rods are packaged in a double flask with individual markings. The serial number is entered into the patient's record upon installation.

The products are highly sterile, which eliminates the risk of infection. The radiation method is used for sterilization. The advanced set of implants includes:

• patient passport;
• work protocol for an implantologist;
• sterile napkin;
• flask holder.

Product range

The company produces several types of implants:

1. Classic - products have a triangular classic thread and a cylindrical shape. They are simply installed on the desired area of ​​the gum.
2. Classic Conus is a cone-shaped model. Before installation, the product is secured to the abutment, which ensures better fixation of the material.
3. Active is a spiral-shaped product equipped with a triple thread and is installed for all types of dental problems. The rod is suitable for immediate implantation.
4. Active Conus - analogues Additionally, the material adheres to the abutment.
5. Active Plus - the upper part of the implant has the shape of a thread. The main purpose of the device is to redistribute the load between dental tissues and prevent their resorption.
6. Integral – model with abutment. Installed without incision of soft tissues during one visit to the doctor.
7. Slim. A thin conical rod is installed in the case of a narrow ridge or with closely spaced natural teeth, as well as in the case of temporary restoration between already installed permanent rods. The product assumes immediate loading.

The video provides an overview of the updated line of Alpha Dent implants.

How are implants of other systems different?

Many patients ask about which implant is best to install. In the ranking of dental systems, Israeli Alpha Bio and German Ankylos occupy good positions:

1. Alpha Bio implants come in 4 types: Spiral, Arrow Press, Alpha-Tec, Dualfit. They differ from each other by the type of thread. There are models for atrophied bone. The surface is treated with a special compound for reliable fixation in the tooth socket and improved performance.
2. Universal Ankylos implants are made of titanium and zirconium oxide. The relief surface is created by jetting. Equipped with a specially designed progressive thread for implantation into bone of any density and volume. The crown is placed just above the gum, which guarantees a natural appearance.

Alpha Bio implants – pros and cons

The Alpha-Bio implant system has quite a lot of strengths, but still these implants remain economy class and will not be able to give an ideal result in most clinical situations (24stoma.ru). The best implants from this company are NEO1, NEO2 and SPI. Implants of both NEO series have the ability to be fitted with metal-free ceramics made of zirconium dioxide using CAD/CAM technology.

This option of prosthetics will allow you to make not only a crown from ceramics, but also an individual ceramic abutment (which will have a better effect on the aesthetics of the gums). Another advantage is that the line includes implants for narrow spaces, for example, for a narrow alveolar ridge. Well, their main advantage is their affordable price. We will move on to calculating the turnkey price below.

Installation of the Alpha-Bio implant: video

In this video you can see the installation of 2 Alpha-Bio implants of the “NEO” series - in the area of ​​the lateral upper jaw (the diameter of both implants is 3.75 mm).

Disadvantages of the AlfaBio implant system –

1) The disadvantages include the “Nano Tec” surface itself. This is certainly a high-quality SLA surface with microporosity from 1 to 5 microns, which will give a good result when using a two-stage implantation technique and in the absence of a deficiency of bone volume at the implantation site (especially when it comes to implantation in the area of ​​lateral teeth). But as we said above, this surface is still morally outdated in comparison with more modern ultra-hydrophilic surfaces from other manufacturers.

In particular, the lack of increased hydrophilicity makes these implants less attractive in the following situations - 1) if you are planning immediate and early loading, 2) if you are planning a one-stage implantation technique, 3) if there is a deficiency of bone tissue in the implantation area and one-stage bone grafting is necessary plastic surgery, 4) and even more so if you are planning to implant a front tooth in an area with a deficiency of bone volume.

In the latter situation, you should not save on implants at all, because the surface of the implant significantly affects the efficiency of new bone formation around it. And here we need a surface with increased hydrophilicity and a special type of thread around the neck of the implant. As a practitioner, I can say that no implant behaves as well in conditions of insufficient bone volume as Straumann implants with the SLActive surface. Near these implants, bone formation is observed even in gaping type bone defects.

2) The second disadvantage is that AlfaBio implants are made of grade 23 titanium, i.e. made of titanium alloy Ti-6Al-4V. Aluminum and vanadium impurities somewhat worsen the quality and speed of osseointegration. This may be critical if you are planning immediate or early weight-bearing, if you have osteoporosis, diabetes or a smoker, or if you are using a one-stage implant technique. Again, what does the word “critical” mean? Critical in this case means that the risk of implant failure in such situations will be slightly higher - in comparison with implants made from a more expensive brand of titanium without impurities, and even more so if they also have an ultra-hydrophilic surface.

3) Around any implant, after an artificial crown is fixed on it, atrophy of the bone tissue around the neck begins. This is due to the fact that the implant begins to experience chewing load, and it is transferred from the implant to the bone. Moreover, the size of such atrophy is completely different for different implant models. The norm is considered to be 1.0 mm of bone atrophy within 1 year (from the moment of functional load) and then 0.2 mm per year. But such indicators were considered the norm until modern implants from Staumann, NobelBiocare, and AstraTech appeared.

Around the neck of implants from the above-mentioned manufacturers, bone atrophy is practically not observed at all, which is due both to the characteristics of the surface and to the fact that the necks of these implants have a special microthread pattern. Why is it so important that there is as little atrophy as possible? The loss of bone height leads to gum recession (i.e., the level of the gums recedes). At the very beginning of this process, you may notice a loss of volume in the gingival papillae in the interdental spaces, as well as a bluish appearance of the gums around the implant neck.

Further increase in gum recession leads to exposure of the metal neck of the implant. We want to note that the main complaints of patients about the dental implantation procedure in principle - in 95% of all cases - relate specifically to the poor aesthetics of the gums around the neck of the implant. Therefore, if you are planning implantation in the area of ​​the front teeth, as well as in an area with insufficient bone volume, then as an implantologist, I would not recommend Alfa-Bio to my patients. Below in Fig. 17-24 you can see the result of installing the Alpha-bio implant with simultaneous bone grafting, and this result is not very good (we will comment on it below)

4) And we forgot one more important point - never do implantation according to the All-on-4 (or All-on-6) protocol, which are used for permanent bridge prosthetics of an edentulous jaw - using Alpha Bio implants. These implants are not suitable at all for this type of prosthetics for toothless jaws with immediate loading. You will experience very strong bone resorption around the implants within the first few years of functional load, which will lead to early failure of the structure.

If you have a toothless jaw and you are planning budget implantation using Alpha Bio implants, the choice should be made in favor of the classic two-stage implantation method, with the implants engrafting within 3-6 months (all this time you will wear a temporary removable denture). And only after this time can a permanent fixed bridge prosthesis be made. Only in this case, the design on these implants can serve you for a long time.

When choosing Alpha-Bio may be optimal -

If you plan to carry out the safest option - a two-stage dental implantation technique, in which the implant is engrafted under a tightly sutured mucous membrane, and prosthetics will begin no earlier than in 3-6 months. At the same time, there should not be a deficit of bone tissue volume in the implantation zone, and this is absolutely good - if we are talking about implantation of the lateral group of teeth.

Or the second option is when you have a limited budget and you don’t want to grind down adjacent teeth for crowns. But in this case, you will have to sacrifice the aesthetics of the gums, although if you are planning implantation in the area of ​​​​the lateral teeth, then this may not be so important.
