> Treatments > Implantology - white implants In case natural teeth are lost, there is a possibility to replace them with implants. In most cases it is possible to implant. We differentiate the immediate implantation (implant is placed straight after the tooth removal), the delayed implantation after approx. eight weeks and the socalled late implantation. In case there are not enough bones, it is possible to restore those using different bone construction techniques. In aesthetic implant surgery, the precondition for success is the preservation or restoration of primal, natural bone size. |
1) The jaw bone will prepare for the implant. 2) The implant heals after the integration in. 3) After the healing phase the implant will prepare for the artificial tooth. 4) The artificial tooth is integrated. |

Natural hard and soft tissue contours enable both the ideal implant position and the ideal appearance of the prosthesis, thus offering a harmonious relation to the neighbouring teeth and being free from prosthetic compensation. To obtain an ideal implant aesthetic may be as simple as the replacement of tooth deemed not worthy of preservation using the immediate implant in order to preserve the condition of soft part architecture. |
Correspondingly, in order to enable aesthetically satisfying results for the implant patients, the treatment duration extremely varies, e.g. three month for uncomplicated immediate implant or two years or more for complicated cases. However, it may be also complex and the multiple sequences of therapies, jaw orthopedia, multilayer reconstruction of hard and soft parts from implants and the cosmetic periodontal surgery will be necessary in order to ensure the harmony with the neighbouring teeth. Titan versus zirconium dioxide. |

Zirconium dioxide as a ceramic material for crowns and bridges has found one's way into oral implantology. It forms - like the long-proven metal titanium - the framework and is veneered with tooth-colored porcelain. In addition has the material good biological, physical properties and aesthetic qualities. In the case of degeneration of the tooth socket is the silver-gray color of the titanium implant visible, for the bright zirconium dioxide is not a problem. The main characteristics of both types of implants on a quick look: |
Properties of titanium: - Classical - Metal - Titanium particles in the surrounding tissue - Partial titanium particle incompatibility (30-40%), particle test necessary - 1% real allergie - Increased risk in grade 3/4 responders (patients with increased tendency to inflammation) - Ageing - Gap with corrosion, anaerobic crypts - Aesthetically sometimes deficient, grey translucency - Complex and many parts - Much experience |

On the subject of titanium incompatibility Titanium incompatibility is usually not an allergy, but the consequence of an increased inflammatory reaction. Titanium particles are phagocytosed by macrophages and trigger an inflammation. Titanium incompatibility is diagnosed with the titanium simulation test. A positive result can mean titanium incompatibility. The titanium simulation test correlates to the degree of tendency to inflammation (see "high responders") Implants made of zirconium dioxide are alternatives. "High responders" - Knowledge of the degree of inflammation enables failures to be estimated before implantation with titanium materials. Grade 3 and grade 4 patients, so-called high responders, are risk patients for titanium implants. There is a correlation between high responders and patients with titanium particle incompatibility. |
Charakteristiks of zirconium dioxide: - New - Non-metallic - Biocompatible - No gap, no corrosion, no anaerobic crypts, since made from a single piece - No ageing - No to scarcely any periimplantitis - No particle test necessary - No bone loss - Aesthetically superior - Simple and few parts - Less experience - in the meantime 5 years with FCD (Feith Ceramic Dental) - Oxide ceramic is extremely resistant to corrosion - Particles are not toxic - Cerium partially stabilises, ages scarcely to not at all and is elastic - Fractures are possible despite high strength |
