DENTAL IMPLANTATION

Today, dental implantation is the most effective method of restoring dental defects in the world. It is the most advanced technology with many advantages: a crown made on a dental implant is aesthetic and functional, it does not differ in appearance from a real tooth. For example, STRAUMANN dental implants are covered by a lifetime guarantee (technical cost of the implant and crown).

Advantages of dental implants

Nature-like appearance of dental crowns on implants.

Alternative methods of replacing lost teeth involve the fabrication of bridges or removable dentures. Almost always, after wearing a bridge or removable denture, a major restoration of bone and gum tissue volume is required, which is comparable or more expensive than a simple implantation of a tooth immediately after its extraction.

In most cases, bridges require grinding down the supporting teeth (there are always at least two supporting teeth, as single-support bridges are prohibited) to a thickness of 1.5 - 2 mm around the entire perimeter of the crown part, which means that they must be depulped beforehand. Currently, there is no guarantee for quality tooth depulping, it is a very complex and often unpredictable process, which can lead in 5 - 6 years to the development of inflammation and as a consequence, the loss of the supporting tooth. As a result, the supporting tooth will have to be extracted and a new bridge with more ‘suspended’ teeth and new ‘victim’ supports will have to be planned. From a biomechanical point of view, it is preferable that each tooth is only responsible for itself. The tooth is fixed in the bone alveolus by special shock absorber fibres, which distribute the load evenly. If the tooth is overloaded (in this case it is the addition of suspended crowns), irreversible processes of soft tissue (gum) and bone loss around the supporting tooth may occur, which leads to unaesthetic appearance and loosening, loss of the supporting tooth, development of inflammation around it. Often, when it is necessary to prosthetically replace the area of the tooth row where the ‘suspended’ crown was located, we are faced with a lack of bone and gum, just as when planning to replace a tooth where inflammation and gradual bone loss have been developing for a long time.

Of all types of removable dentures that are supported by natural teeth, we only fabricate telescopic dentures. They are the only ones capable of competently distributing the load on the supporting teeth for many years without destroying themselves and the surrounding bone and gum. This type of prosthesis requires the mandatory depulping of all supporting teeth. In our clinic it is forbidden to make bridges in combination with all kinds of support elements for removable dentures.

When a tooth is extracted, there is almost always irreversible loss of bone and gum. Although it is possible to place an implant even with a minimal amount of bone and gum, the long-term result of such an intervention will be disappointing: lack of aesthetics, inflammation, over-implantitis, loss of the implant, re-implantation in more difficult conditions.

Tooth implantation involves screwing a titanium implant into a pre-prepared bed in a sufficient volume of bone, forming the gingival part, making and screwing the dental crown to the implant.

Methods of dental implantation

If the conditions exist, implantation can be carried out immediately after tooth extraction (one-stage implantation) or after the healing of the extracted tooth (two-stage implantation). The optimum time for implantation after tooth extraction is 8 weeks. Bone and gum augmentation can be done in two ways.

The process of dental implantation

Before dental implantation, it is recommended to make a surgical template, through which the implant site can be prepared with perfect precision exactly where it is needed, according to the CT scan.
