We predominantly use full titanium screw implants that have been in clinical use for decades (clinical use on patients began in 1965). For each indication, a suitable screw is available with different lengths, diameters, surfaces, designs (parallel-walled / conical), helical pitches, etc. More recently, zirconium oxide (Zr0) all-ceramic implants have been used in selected cases.
Both materials are highly tissue-friendly (biocompatible) and are not recognized by the body’s immune system. Therefore, they are also considered safe for allergy sufferers.

General information about implants
Practical implants, available in this or modified form today, were developed in the 1960s. These are today pure titanium screws, the developments focused initially on the type of threads, changes in the helical shape and the diameter, new developments of the dental prosthesis auxiliary parts and since the turn of the millennium of the implant surface. Over such implants there are follow-up examinations over partly several decades with recognized very high Einheilwahrlichkeiten. If successful, a dental implant as "lifetime"-Serve solutions, failures after dental prosthesis supply are essentially based only on infections ("periimplantitis") and technical complications such as fractures on implant and abutment parts and wear of the associated "Kaueinheiten".
In addition, metal implants are currently being used to reduce the classic healing times of at least three months in the lower jaw and six months in the upper jaw ("Teeth in an hour").
This is made possible by a complex preoperative diagnosis to determine the existing bone quality and the ideal implant position in the jawbone and new screw surfaces. The use of regenerative procedures and patient plasma can increase the rate of healing and improve well-being.
In the case of unfavorable bone density or in connection with bone superstructures, the probability of their likelihood of being healed on temporary implants can be increased by means of temporary restorations (temporary restorations) on additional provisional implants because it can no longer lead to incorrect loading. The patient is still not toothless.
The practice equipment
We have a recognized quality management system and ensure sterile conditions and reproducible workflows.
In addition to the classical model and two-dimensional X-ray analysis, special three-dimensional evaluations have increasingly come to the fore in planning (dental volume tomogram, DVT). The practice prescribes all diagnostic procedures.
Special torque-indicating surgical motors provide intraoperative information about the bone quality encountered; the intraoperative diagnostics will be extended.

Dental implants made of titanium
Titanium implants are regarded as the gold standard, for them there are sufficient study results in terms of survival of the screw and the crowns as well as with regard to the expected complications over the wearing time. As a rule, titanium implants are multi-part, so that applied by screwing on the same implant body depending on the clinical application different structures or they can be changed in a change in findings.
Zirconium implants have advantages in some aesthetically sensitive areas and in people who do not want to use metal bodies. They appear to be particularly biocompatible.
The original one-piece implants (the implant body anchored in the bone and the abutment are connected in one piece) are impressive in addition to the bright color due to their special tissue-friendliness. Long-term results are still pending. Ideally, the implant is also supplied with a conventional all-ceramic crown made of zirconium oxide.
Recently, split, ie two-part implant systems made of zirconium dioxide have come on the market. A screwing as with titanium implants is not yet possible safely. The structure is glued to the implant body.
A combination of the static advantages of a split all titanium implant with the tissue friendliness of the cicron oxide are screw-on zirconium abutments on titanium implants.
Applications of Dental Implants / Examples
Implants secure anchored crowns and bridges, partial dentures and total dentures.
Bridge constructions can be carried out purely implant-borne as well as in combination of teeth with implants. Long-term statistics on the survival rate of implants show slight advantages for purely implant-supported dentures.
are a proven remedy for the treatment of highly shortened rows of teeth in the posterior region, thus avoiding removable partial dentures. They can also be used to replace a partially broken row of teeth.
Implants for removable attachment of total dentures:
Removable dentures can be held securely by means of implants in place, so that pressure points can be largely avoided and safe bite off can be made possible. Classic methods for removable total dentures are bar constructions (below) or the use of locators (top). If the number of implants is low, dental care can be provided after a healing phase, with higher numbers of implants, especially in the lower jaw, as immediate restoration.
and when you turn this dentures, you recognize the basic features of a stable-base construction again.
Clearly recognizable the fine structure of the cast base, this denture is not loaded on tilting.
Implants for pillar augmentation
Implants for pillar augmentation are used as additional static supports, here using the example of a removable denture. This avoids the grinding of additional abutment teeth.
solid implant-supported constructions:
For fixed dentures in the edentulous jaw we need at least six implants per jaw if there is sufficient bone supply or in connection with bone structures. Alternatively, bridges can also be designed palate-free and removable.
A special form, originally designed for patients with severe bone loss or extreme jaw atrophy, designs on only four implants per jaw "All-on-four" The concept described dates from the 1990s. There are four implants here angulated built-in implants (the oblique arrangement in the bone allows, inter alia, a larger implant length) fixed reconstructions already applied shortly after implantation. It is largely dispensed with bone structures. The stability results from the rigid connection of the implants over the dentures. Depending on individual circumstances, there are several planning options for fixed dentures according to this concept. A peculiarity of this form of care is that fixed teeth immediately, i. can be placed within one day immediately after implant placement. Please, let us advise you.
Temporary implants serve to bridge healing times for the implants. As a rule, the small screws dissolve after a few weeks to months.
