History:
For around 50 years now, dental science has been occupied with the problem of replacing missing teeth with synthetic support teeth called implants.
The widest variety of systems has been developed in the course of time (screw type, leaf type and cylindrical implants as well as re-implants).
There have also been advances in the use of implant materials. Today, cylindrical implants made of titanium are used almost exclusively.
The structure of the implant:
Cylindrical in shape, diameter from 3.25 to 4.8 mm, there is a female thread in the body of the implant, which will be used to fix the artificial tooth later on.
Installation of implants:
With the help of a panoramic x-ray image, all the teeth and the periodontium (tooth bed) will be checked for inflammations if any. The precondition for an implant is a properly sanitised chewing mechanism – in other words, cysts, granuloma, foci of infections, periodontal infections and badly made fillings should first be removed.
The x-ray images will be scanned into the computer and a diagnosis will be made using an implant planning and bone density analysing program (FRIA-COM) in order to achieve absolute certainty concerning optimum placement of the implants.
After anaesthesia, around 4 mm of the gum in the area into which the implant is to be installed will be cut out. The implant depth in the bone is set with a pilot drill, and the implant bed in the bone is drilled out step by step. Finally, the sterile implant will be unpacked and screwed in, so as to closely seal the edge of the bone. As a rule, the gum above the same will be stitched up.
Thereafter, a compulsory healing phase of three to six months has to pass. After this healing phase, the implants are reopened and a supporting member is screwed into the female thread of the implant; it now looks like a ground-off tooth.
The relevant tooth replacement can be placed on this supporting member.
Risks:
Rheumatic disorders, osteoporosis, or infections of all types, that can occur during the healing phase of the implant bed in the bone.
Implant systems:
We use globally accepted systems in our clinic, namely Pitt Easy, Frialit II, Steri Oss (all cylinders with a hydroxilapatite-plasma frame-coat).
The system
The two-phase Pitt-Easy cylinder shaped implant is made of pure titanium, with two different surfaces:
• With V-TPS-coating (Vacuum-Titanium-Plasma-Spray-coating) for the tried and tested therapy. The Vacuum-Titanium-Plasma-Spray-coating enlarges the surface six times and thereby enables contact osteogenesis and osseo-integration.
• With FBR-coating, to reduce the regeneration time. The new bioactive Fast Bone-Regeneration-surface is the “Turbo” model amongst the surface treatments. It achieves upto 23 percent higher bone addition in comparison to other raw surfaces, and has a high capillary effect for intensive, quick anchoring. The purely synthetic material made of resorbable calcium phosphate is also applied to the tried and tested V-TPS coating. The new bone grows within six to twelve weeks maximum. The flexibility of the surface also makes insertion easier.
Pitt-Easy is available in 5 diameters and 9 lengths, extending from 8 – 24 mm. The colour control system offers the doctor, assistants and dental technicians certainty over the entire line.
Indication
This is where system proves its versatility: The Pitt-Easy cylindrical implant is the optimum solution for not only individual tooth replacement and gaps, but also in free-end situations and upper and lower jawbones without teeth.
The essential characteristics
• The self-tapping expansive thread eliminates the need for pre-cutting the thread. The minimum trauma caused ensures quick bone regeneration. The apical cutting notches offer an additional protection against rotation.
• The new double-coating FBR also makes possible rapid osseo-integration in case of D3 and D4 bones. With FBR, dentures in a set can accept a progressive load immediately, and in the case of single dentures, loads can be applied as early as six weeks after the operation.
• Simple insertion techniques with standardised simultaneous drilling for every implant length and every implant diameter guarantees high insertion safety.
• Guarantee of a high success rate.
Aesthetics
The particularly comprehensive range of prosthetics offered allows optimum individual solutions - from the technical as well as the aesthetic point of view - and is continually being developed further. Some examples:
• From the new individual supporting member, tailor-made individual solutions can be prepared, for example if a supporting member has to have an angle of more than 25° to ensure symmetry, or if an unusual gingival contour requires a circular step – all these are possible.
• The new V.D.L. Anatomic Line makes it easier for the dental technician to prepare an exact, clearly defined crown termination. The sub-gingival external contour of the new supporting member allows not only a highly individual adaptation to gingival contour, but also to the individual anatomical tooth cross-section - which is particularly important in case of thin incisors.
• The new Ceramium Line for the final replacement is the only ceramic supporting member with a basal precious metal compound (no yirconium oxide) and anatomical contouring. Totally natural-looking solutions are made possible. |
