Replacing One Tooth

A crown mounted on a dental implant is the best choice if you have a tooth missing in the upper or lower jaw. The need to replace a missing tooth could be the result of an accident or because there was no predisposition for a tooth at birth.

Treatment Overview

A thorough examination

The first step in dental implant therapy is a discussion with your dental professional, followed by a thorough dental examination. The jaw is x-rayed to check the condition of the bone tissue and to determine the placement of the dental implant. An impression is made of the jaw and existing teeth, forming an important platform for the treatment.

Inserting the dental implant

There are two options for dental implant placement depending on your clinical situation. In a one-step procedure, the dental implant is put in place and a temporary abutment is attached. In a two-step procedure, the dental implant is installed and then covered by the gum. The abutment is attached at a later date.

In both cases, a temporary tooth or prosthesis is put in place, followed by a maximum healing period of three months for the lower jaw and six months for the upper jaw. In some cases, the dental implant can be loaded immediately although this depends on your bone condition.

Attaching the abutments

In a one-step procedure, the temporary abutment is replaced by a permanent one after the dental implant has bonded with the bone tissue. The second part of a two-step procedure involves making a minor incision to open the gum and put the abutment in place.

Producing the teeth

When the abutment is in place, a new impression is made. It is then compared with the impression made during the initial examination. Based on a final model, a dental technician carefully crafts the crown, bridge or prosthesis. Special attention is given to ensuring the right color and shape so that your new teeth look like your natural teeth. 

Fitting and re-examination 

When the teeth are ready, your dental professional simply attaches them to the dental implants. This is usually followed by a few follow-up visits to check functionality and esthetics and to make sure you are completely satisfied with your new teeth.

Healing period 

When you are ready for a dental implant, you will have a solution tailored to your needs, general state of health and the quantity and quality of your bone tissue. These factors also determine the total duration of the treatment. Consult your dental professional for your specific options.

Step by Step

Step 1

The need to replace a missing tooth could be the result of an accident or because there was no predisposition for a tooth at birth.

Step 2

The dental implant is installed in the jawbone. No healthy teeth are affected or damaged. With other replacement solutions, adjacent teeth might need to be ground down to support a bridge.

Step 3

The abutment is attached to the dental implant. A crown is then placed on the abutment, fitting perfectly at the edge of the gum.

Step 4

The new tooth is now complete and it is virtually impossible to see the difference between the existing teeth and the new tooth.

Astra Tech Implant System

Astra Tech Implant System : Developed with a biological and biomechanical approach

To put it simply, with the Astra Tech Implant System™, esthetics are integrated into the implant system design. We work together with nature in supporting the natural healing process instead of interfering with it. That is why you and your patients can rely on the Astra Tech implant system, not only today, but also tomorrow and beyond.

A successful implant system cannot be determined by one single feature alone. Just as with nature, there must be several interdependent features working together.

A unique combination of key features

OsseoSpeed™ – more bone more rapidly

Building on the proven success of TiOblast™, OsseoSpeed™ is the first and only implant in the world with a chemically modified titanium surface, providing unique nano scale topography, that stimulates early bone healing and speeds up the bone healing process.

The result of the micro-roughened titanium surface treated with fluoride is increased bone formation and stronger bone-to-implant bonding. Together with MicroThread™ on the implant neck, OsseoSpeed provides true growing power in action for more reliable and effective treatment. The clinical benefits of OsseoSpeed are proven and well-documented.

MicroThread™ – biomechanical bone stimulation

The neck of Astra Tech implants are designed with MicroThread™— minute threads that offer optimal load distribution and lower stress values. This design is based on a thorough understanding of bone physiology, vital to optimal implant design. Since bone tissue is designed to carry loads, dental implants must be developed to mechanically stimulate the surrounding bone in order to preserve it, taking into consideration that the critical point of the implant-bone interface is located at the marginal cortical bone where peak stresses occur.

Conical Seal Design™ – a strong and stable fit

The Conical Seal Design™ is a conical connection below the marginal bone level that transfers the load deeper down in the bone. Compared to conical connections above the marginal bone level and flat-to-flat designs, Conical Seal Design reduces peak stresses and thereby preserves the marginal bone. It also seals off the interior of the implant from surrounding tissues, minimizing micro-movements and micro-leakage. Conical Seal Design simplifies maintenance and ensures reliability in all clinical situations. What's more, the tight and precisely fitting implant-abutment relation of the Conical Seal Design makes abutment connection a quick and simple procedure. The abutment is self-guiding and the installation procedure is non-traumatic, eliminating the risk of bone damage.

Connective Contour™ – increased soft tissue contact zone and volume

The Connective Contour™ is the unique contour that is created when you connect the abutment to the implant. This contour allows for an increased connective soft tissue contact zone both in height and volume, which integrates with the transmucosal part of the implant, sealing off and protecting the marginal bone


Astra Tech BioManagement Complex™

Our way of safeguarding a reliable, predictable and esthetic result both in the short- and long-term, is with the Astra Tech BioManagement Complex?. This is a unique combination.

The unique soft tissue seal on the abutment level, together with well-calculated biomechanical interactions with the bone around the implant neck, ensure optimal conditions for the bone. The load distribution and the lack of micro-movements and micro-leakage are the main reasons for maintained healthy peri-implant tissues and preserved marginal bone levels.

Why accept bone loss?

When it comes to implant treatment, peri-implant soft-tissue architecture and texture, in combination with maintained marginal bone levels, are absolute prerequisites for long lasting esthetic success.

Under the right conditions, nature itself does the major part of the job. The Astra Tech implant system is designed to provide nature with the right conditions; all of the system's parts work together for reliable clinical success. In fact, the system offers unrivalled, documented results when it comes to the maintenance of marginal bone integrity and soft tissue health.

A holistic approach


To design a successful implant system, one needs not only a great deal of knowledge about biology and mechanics, but also an understanding of what happens when the two interact.

Early on in the development of the Astra Tech implant system, we realized the value of a holistic approach. That is why the Astra Tech implant system was uniquely based not only on a biological but also a biomechanical approach

With the introduction of the OsseoSpeed surface, providing unique nano scale topography, we have taken this to the next level by incorporating biochemistry. Just as in nature, a successful existence cannot be determined by one single element alone. The terms biomechanics and biochemistry are no longer sufficient as there must be several interdependent features working together. This interaction is what we call the Astra Tech Bio Management Complex.

SLActive – Surface technology

Groundbreaking clinical results strongly support the benefits of SLActive

SLActive, the next generation in implant technology was supported by more scientific studies than any other dental implant technology at the time of market launch.

The new Straumann surface optimizes implant stability in the critical early treatment period, thereby enhancing treatment predictability. It offers new treatment options linked with more security for clinicians and patients.


Surface Innovation

From surface topography to surface chemistry

We look back on a long tradition of pioneering implant surfaces, having developed the ground-breaking SLA® surface in 1994.

This surface reduced the average healing time from 12 weeks (TPS surface) to only 6-8 weeks. Shortly after its introduction, the macro- and microstructured, osseoconductive SLA® surface became the gold standard in implant technology.

The SLActive surface takes the proven concept of SLA® one step further to set the new surface benchmark. Due to its surface chemistry, SLActive accelerates the osseointegration process, leading to increased predicatability in all treatment plans and shorter treatment times.


Clinical Impact

Increased treatment predictability in every indication

SLActive provides significantly more bone-to-implant contact two weeks after insertion compared to SLA®, as shown in animal studies. This substantially higher BIC-value results in improved treatment predictability for all protocols.

Shorter treatment times

SLA® set the gold standard by cutting healing times in half, from 12 weeks to 6-8 weeks. SLActive further reduces healing times by reliably offering sufficient secondary stability for early loading at 3-4 weeks after implant placement.

Expanded treatment options

Implants with the SLActive surface are suitable for all indications, and are especially beneficial in advanced and complex treatment protocols in challenging indications such as immediate loading.
