Straumann implants (Strauman): advantages, description of varieties

Model range Disadvantages Indications and contraindications Installation steps Prices Comparison with other brands How to choose a clinic?
When back in 1974, a small Swiss company released its first implants, no one could have thought that this was the first step towards world leadership in the field of implantology and restorative dentistry. Today, Swiss Straumann implants are known throughout the world. They are preferred by implantologists from all continents, because the products of this brand combine high quality, a scientific approach and a full set of related materials. Strauman implants don’t just restore your smile—they restore your self-confidence.

All the company's products are based on scientific developments. Therefore, the company has many technological breakthroughs in the field of dental restoration and implantation.

When is prosthetics indicated?

Installing a crown on a tooth is a necessary procedure in situations where the patient:

• the tooth is destroyed as a result of injury, abrasion of enamel or carious lesions,
• extensions, fillings and other treatment methods are not possible,
• the root remained intact.

Some defects, including discoloration of the enamel, lead to an unaesthetic appearance of the entire dentition. The crown will protect the tooth walls from external impacts. Tooth mobility is caused by various periodontal pathologies. In this case, the use of temporary crowns is considered, which make it possible to strengthen the teeth and make them more stable. Crowns are also placed on healthy teeth, which act as support for defects associated with the installation of bridges and dentures.

Features of Neodent products

Appearance and material

The manufacturer uses only Ti Grade 4 for Neodent implants - high-quality titanium of the highest degree of purity. The material does not contain potentially dangerous additives, is 100% compatible with the human body, does not corrode and has increased strength. Moreover, the original characteristics of the material are preserved for decades.

As for the shape of implants, Neodent offers all possible options - classic root-shaped, cylindrical, shortened, elongated models, as well as ultra-long zygomatic modifications for installation on the upper dentition. They are used for delayed and immediate prosthetics. That is, for any patient, regardless of the severity of the situation, a solution can be found.

NeoPoros surface

NeoPoros coating is an analogue of the SLA surface from Straumann, i.e. treatment of the implant with abrasive particles and acid etching. The resulting rough relief contains many micropores with a diameter of 15 microns, and the surface contact area with the bone increases by approximately 50%. The roughness of the relief is necessary so that more points appear for the attachment of fibrin protein filaments, along which osteoblasts - young bone cells - migrate. As a result, osseointegration (fusion with the bone occurs faster), and bone tissue grows more densely.

Hydrophilic surface Acqua

Acqua is a hydrophilic surface of the Neodent implant, developed on the basis of NeoPoros. That is, it is an improved SLA surface that is almost instantly wetted by biological fluid (blood) when installed in the bone. After all, some of the building components are attracted from the blood - fibrin protein and calcium, for example. Therefore, the osseointegration process starts immediately, and not after a few days.

The combination of increased hydrophilicity and a rough coating is important for patients with “soft” bone, because engraftment - osseointegration, occurs quickly and with a very good prognosis. Therefore, hydrophilic surfaces are recommended for immediate prosthetics, especially in difficult clinical conditions.

Grand Morse and Cone Morse connections

Neodent offers two types of conical connections between implant and abutment. The first is a classic Morse cone (Cone Morse) with an angle of inclination of the lower walls of the abutment of 5 degrees. The second is a unique conical connection called the Grand Morse with a 16 degree angle. In both cases, the abutment is installed very accurately and hermetically, so germs do not penetrate inside.

Any twisting or displacement of the Grand Morse is eliminated thanks to anti-rotation stops, and it is also extremely stable under load. Grand Morse promotes uniform distribution of chewing pressure on the bone. This stability is maintained for many years. The absence of the “cold welding” effect between the implant and the abutment makes it possible to very quickly replace the latter if necessary.

Aba variety

Abutments for Neodent implants are available in all known shapes and types - these are straight abutments for strictly vertical installation of an implant, inclined and angular multi-unit abutments for implants implanted into the bone at an angle of up to 45 degrees. The manufacturer produces abutments for cement and screw fixation. And also for temporary and permanent prostheses, for removable and non-removable orthopedic structures. There are abutments for milling attachments for a crown using a CAD/CAM system, and abutments with a titanium base. Let's take a closer look at the available varieties:

• screw-retained abutments: Micro Conical 0°/17°/30°, Mini Conical,
• with cement fixation: Anatomic, CM 0°/17°/30°,
• for cement and screw fixation simultaneously: SM and C (titanium base), cobalt-chromium GM Co-Cr, Universal,
• removable (conditionally removable) dentures are fixed on the CM Equator and Equator Attachment abutments,
• temporary Pro Peek.

The versatility of the Neodent brand for different implantation methods

Thanks to the use of high-quality materials and progressive developments, Neodent implants are considered universal products. They are indicated for installation according to any known implantation protocols, for example, the following:

• one-stage implantation with immediate prosthetics: the main direction for which Neodent products are created. The prosthesis on the implants is fixed within 3-5 days from the date of surgery. The method is suitable if a large number of teeth are restored at the same time or a completely toothless jaw,
• two-stage implantation with delayed prosthetics: after the operation, the implants are left alone for 2-6 months until complete engraftment, and only then a prosthesis is installed. The method is more relevant if only 1-2 teeth are restored,
• one-stage implantation: this is an additional technique that is combined with two- and one-stage technology. The point is that the implant is placed immediately after the removal of the diseased tooth, i.e. There is no need to wait for the hole to heal. However, such removal must be planned several days in advance.

Sterile packaging

Neodent structures are stored and transported in individual double-layer packaging, which provides reliable protection from damage and contamination. You can remove the implant from it using an implant driver (this is a dentist’s tool) and install it immediately.

Types of Dental Crowns

There are different options depending on the raw material from which they are made. Each of them has its pros and cons.

Metal

Classic dentures in dentistry. Currently, inexpensive alloys made from medical steel, which is not subject to oxidation and is a durable, wear-resistant material, are often used for the manufacture of orthopedic structures. Disadvantages include an unaesthetic appearance and the risk of allergic reactions. Such dentures are installed on chewing teeth, which are not visible when a person talks or smiles.

Metal ceramics

Such crowns are durable and aesthetically attractive. In addition, their cost is significantly lower than all-ceramic analogues. The disadvantages of this type of prosthetics is that it is impossible to achieve the effect of transparency of the cutting edges in the prosthetic group of the anterior teeth.

Ceramics

The most attractive and expensive option. All-ceramic dentures are made from porcelain processed on a special milling machine. They are very similar to natural teeth. However, ceramics are fragile and cannot withstand significant chewing loads. Therefore, dentures made from it are used to restore front teeth.

Zirconium dioxide

It is not inferior in strength to natural tooth enamel. The material is suitable for the manufacture of solid bridges. The shade of zirconium dioxide can be matched exactly to the color of the patient’s natural teeth. The crowns are completely biologically compatible and safe for human health. They are suitable for patients with metal allergies.

Glass ceramics e.max

The most modern denture technology. The structure of the material is closest to tooth enamel. Externally, crowns are indistinguishable from natural teeth. Glass ceramics are biologically inert and hypoallergenic, while they are impervious to dyes and odors.

Straumann implant models

Straumann in Switzerland is continuously working to expand its product range to meet individual patient needs. In collaboration with the International Team for Implantology (ITI), new implantation models and technologies are being developed. Currently, the brand offers several options that differ in design and purpose. All models are united by innovative technologies:

• Bone Control Design
  is a development that preserves the volume of soft tissues and the alveolar ridge.
• Roxolid
  is a titanium-zirconium alloy that is ideal for rapid osseointegration. This alloy is superior to titanium in its strength. Great for small sizes. Helps preserve bone tissue. Products made from this alloy have a lifetime warranty.
• synOsta
  is a connection that prevents movement of the abutment and ensures its precise fit. Makes it possible to try on, rearrange abutments, and take an impression if one is missing.

How is a crown placed on a tooth?

The procedure takes quite a long time and consists of several stages.

Preparation. At this stage, the doctor draws up a treatment plan, which will depend on the complexity of the particular case, prescribes an x-ray examination and discusses with the patient how the crowns will be installed.

Preliminary treatment may require the removal of teeth if they cannot be restored. A bridge prosthesis involves the use of fixation of several supporting teeth, and one of the points of the plan may be the process of clarifying their number. After this, the cost of installing crowns on the teeth is calculated, and the time frame for manufacturing the prosthetic lock and adaptation to the patient’s oral cavity is determined. After all the preparatory stages before prosthetics, the patient is invited to an orthopedic dentist to treat the supporting teeth and make an impression.

Removal of damaged tissue is carried out using local anesthesia. This also applies to tooth depositing, since during preparation the bur may touch the gums, which may cause discomfort. The condition of the tooth tissue is assessed taking into account the thickness of the crown being installed. Grinding results in the fact that only a stump remains, on which the prosthesis will later be installed.

Making a crown. The doctor takes impressions after preparing all the teeth that will be fixed with single crowns or bridges. Additionally, a 3-dimensional model is created using endoscopic equipment. Using impressions and scan data, dental technicians in the laboratory cast plaster models that are used directly to make the crowns.

Dentures can be made from various materials according to the patient's choice. If the process of producing crowns takes a long time, the patient is provided with plastic structures during this period. This approach not only helps maintain the aesthetics of your smile, but also protects already treated teeth.

Crown fitting. Performed to determine the accuracy of the shape and color of dentures. If the crown fits perfectly, its base is covered with a special ceramic mass. The fitting process can take a long time. At the preparatory stage, the patient will have to visit the dentist at least 2 times. The length of time spent in the doctor's office depends on the condition of the patient's denture. Subsequent production of the prosthesis in the laboratory may take several weeks. Installation of the prosthesis using temporary cement can take about a month.

Installing a crown on a tooth. If the prosthesis is ready, the structure is installed using special cement. Initially, a temporary composition is applied, which allows you to safely control the position of the prosthesis and the reaction of neighboring teeth. If the patient does not experience discomfort, permanent crowns are installed. The choice of method depends on the degree of tooth decay.

Reviews

The Straumann implantation system is known all over the world and is very popular. Yes, the price of the components is on average 5–15% higher than other analogues, but their quality is confirmed not only by certificates, but also by reviews from grateful patients.

Contraindications for prosthetics

In some cases, installation is impossible due to concomitant diseases. Local contraindications are:

• the presence of foci of inflammation in the oral cavity;
• insufficient hygiene;
• bleeding gums.

The list of general contraindications includes:

• pathologies limiting surgical intervention;
• allergic reactions to anesthetics;
• chronic diseases of the heart and blood vessels;
• diabetes;
• oncological diseases in the stage of decompensation;
• bleeding disorders;
• mental pathologies;
• exhaustion of the body after long-term drug or chemotherapy.

In addition, it is recommended to postpone prosthetics during pregnancy and lactation.

One Step Hybrid implantation technique

Neodent has developed the One Step Hybrid single-stage implantation technology for patients with “soft” bone types III and IV. The essence of the method is that 5 implants are installed on a toothless jaw (lower or upper) - vertically in the front zone, and inclined at the sides. Titamax EX models are used. Over the course of several days, the systems are loaded with a fixed prosthesis on a cast frame. The prosthesis is fixed on the abutments using cement, and there is no need to undergo re-prosthetics after 6-12 months, because the prosthesis is permanent. According to studies, the survival rate of implants used with the One Step Hybrid concept within 2 years is 98.2%.

Caring for your teeth after crowns are installed

Dentures are immune to tooth decay, but plaque can accumulate on them. With insufficient oral hygiene, it causes an unpleasant odor and the formation of tartar. As a result, healthy teeth may begin to decay.

Standard care for crowns boils down to preventative brushing of teeth twice a day and visiting the dentist once every six months. It is recommended to use pastes with a low abrasiveness coefficient, and remove food particles between the teeth using an irrigator or dental floss. It is also advisable to rinse your mouth after every meal.

Sudden temperature changes lead to the formation of microcracks in solid materials. To ensure that your crowns last as long as possible, you should avoid eating foods and drinks that are too hot or cold.

Comparison of manufacturers

The table provides comparative data for manufacturers of premium products.

As can be seen from the table, all other things being equal, turnkey Straumann implants are priced close to Nobel brand products and higher than for ROOT products.

Prices for Strauman implants in Moscow differ little from clinic to clinic. If the price is significantly lower, this is a cause for concern. There are no low prices for real company products. Beware of fakes. Remember, Straumann products have no analogues.

Possible complications and ways to eliminate them

In some cases, patients after prosthetics complain of severe pain. The reason may be incomplete sealing of the dental canals, due to which an inflammatory process develops. Pain under the prosthesis can also be caused by the formation of a cyst or the presence of a piece of instrument in the canal. To fix the problem you need:

• remove the prosthesis
• open the channels,
• clean them,
• reseal,
• install a crown.

If there is structural damage to the tooth, cracks or holes at the junction of the crown with living tissue, prosthetic stomatitis may develop, which occurs due to strong pressure on the gums. This leads to poor circulation and bedsores. In this case, re-installation of the crown is also required.

Some patients experience allergic reactions to the material from which the prosthesis is made. Galvanic syndrome is observed if crowns made of different materials are installed in the mouth. Such a proximity is fraught with the appearance of a galvanic current, which stimulates the oxidation process. The patient feels a metallic taste in the mouth and weakness. He has a change in the color of the crowns and teeth next to them.

Removing dental crowns is quite difficult, especially if you need to save the structure for later reinstallation. Help to preserve the denture: special tools, which are hooks, with the help of which dentures are cleaned. In addition, modern dentistry allows crowns to be removed using ultrasound. After treatment, the crown can be easily returned to its place.

Key Product Benefits

Neodent implant systems have earned many positive reviews from dentists and patients - almost 45 thousand professionals choose this brand for dental restoration. Belonging to the Straumann Group and our own developments gives Neodent implants a lot of advantages:

• for the development and study of implantation systems, one of the largest research laboratories is used, where the world's leading specialists work,
• For patients with periodontitis, a unique biogel Emdogain from Straumann is offered: the drug restores periodontal tissue (by 80% in 12 months), after which implantation can be performed. Not all patients need this treatment. And only for those who chose implantation with delayed prosthetics,
• reduction of injuries, implantation time (“time in the dentist’s chair”) and rapid recovery after it: thanks to 3D surgery planning and navigation surgery,
• reduction of implant healing time by half due to the use of Acqua’s own hydrophilic surface,
• the ability to combine implantation with the replanting of high-quality osteoplastic materials BoneCeramic and Botiss Biomaterials,
• production of comfortable and durable prostheses: for this, a modern CAD/CAM complex called CARES is used - the prosthesis is modeled on a computer and milled on a robotic machine under program control.

Immediate loading NeoArch implantation protocol

Neodent offers its version of the one-stage All-on-Four implantation concept called NeoArch (“NeoArc” or “NeoArch”). The essence is similar to the world’s first method of this kind - All-on-4 or “All on 4” from Nobel Biocare, as well as ProArch from Straumann. “NeoArk” is carried out like this: on one row, where not a single tooth has been preserved, 4 implants are placed, and an aesthetic and functional denture is immediately fixed on top. NeoArch uses Helix GM, Helix GM Long, and Zygoma GM zygomatic implants with a hydrophilic surface, which take root quickly and are suitable for all bone types.

Read on the topic: how to distinguish the original All-on-4 from similar All-on-4 implantation techniques.

The manufacturer notes that the prosthesis is conditionally removable (for the doctor, not for the patient). In this case, the orthopedic structure is fixed on a screw fastening, and not on a cement one. Therefore, if necessary, the dentist can easily remove it and put it back. The difference between NeoArch and One Step Hybrid is not only in the number of implants, but also in prosthetics. With NeoArk, immediately after implantation, an adaptive fixed prosthesis is placed, which must be replaced with a permanent one after about six months.
