Implantation stages

  • Implantation stages Technologies of implant setting

Each method of implantation (one-stage or two-stage) foresees separate stages of surgery for implants introduction. Teeth implantation is executed consecutively and requires sometimes a long time, which depends on the degree of difficulty of performed interventions and on individual particularities of the body.
The preparation for teeth implantation. A decisive role in implantation planning plays the type of adentia (teeth loss), method of denture placement, volume and structure of bony tissue in implantation place.
Depending on the type of adentia we choose the form, construction, size and method of implant setting. Before preparing the implantation, accompanying diseases of both oral cavity and of the body in overall are treated, as they can influence directly or indirectly on the process of implant integration.
In surgery a primary importance has the principle of atraumatic technique. Any surgical wound can heal by initial stretching only with the condition to observe the aseptic and perform the surgery intervention with a minimal tissue trauma. The atraumatic surgery technique consists in performing a succession of procedures, envisaging the correct choice of surgical access, a strict observation of rules incumbent upon preparation of bony support, implant setting and closing of surgical wound.

One and two-stage methods of implantation as basic methods of surgery

The оne-stage method uses fixed construction of implant, whose supporting abutment sticks out in the oral cavity. The preparation of bony support is made both by using bloodless method (perforator) without putting in stitches and by cutting the mucous membrane and periosteum, which is performed only on the crest of alveolar apophysis. Then two mucous- periosteum rags are detached, the implant is placed and stitches are put in. We prefer the bloodless method!
Insufficiency consists in the impossibility, with such systems of implants, to produce denture, in order to replace the section of lacking teeth, only on the placed implants. However we face the need of grinding smooth neighbor teeth for joining them to the denture together with implants.

Two-stage method consists in the fact that at the beginning we have to place inside the bone an element and in a certain period of time we place on it the shaper of gingival clasps, later on we can place the abutment or another orthopedic component included in the implant construction. Two-stage method represents the most widely accepted surgery.
I step. After cutting and detachment mucous-periosteal flaps above the alveolar apophysis, follows shaping of bony support drills of different diameter. Then cover screw implant is screwed in the shaped support.
To prevent tissue growing in the internal carved canal, we will screw cover in the osseointegrated element. Mucous-periosteal flaps are put back in the place, and the wound is tightly sewed.
II step. 3-6 months later we determine the location of osseointegrated elements under mucous membrane (with the help of probe or by cutting the mucous membrane). The mucous membrane above the osseointegrated element is excised with the perforator; we screw in the cover and shaper of the gum, which is further replaced by the supporting abutment.
The abutment is places after a complete and safe integration of the implant. It is performed as soon as teeth implants merges with the bone. The abutment (a link joining teeth implant and implant-supported bridge) is crewed in the implant. Now the surgery of dental implantation is carried out and no other surgical intervention is necessary. Healing lasts approximately one week and then we can proceed to the following step – denture placement.

These and other technologies are used in the dental centre “Denta Vita” located in the centre of Chisinau, where our qualified dentists take advantage of all their experience with the help of the up-to-date equipment for our patients’ benefit.
