This refers to the surgical techniques of one implant in the alveolar bone is thick enough and height between the existing teeth. The most common indication is the lack of a tooth between two healthy teeth in patients who, for whatever reason, wish to avoid the preparation of teeth for crowns and bridge development.
SINGLE MISSING TOOTH
Patients in our region, who want implants compensate for the absence of teeth, almost as a rule, go for fixed denture. Empirically, it was found that 6-8 implants, implanted in the jaw without any teeth can carry a fixed prosthetic compensation which contains 12 to 14 crowns. Number of implants depends on their length and diameter and spaced teeth in the opposite jaw. So, for example, six implants with a diameter 4.1 mm, a length of 10 - 12 mm, embedded between the dental opening, can carry 12 crowns, which means that fixed prosthetic restorations can include two distal extension. In doing so, care must be taken to distal implants suffer the greatest pressure of chewing forces. This is especially important if you are in the opposite jaw lateral tooth or fixed prosthetic restorations.
Modern dental implant is a titanium screw that is embedded into the jaw bone and coalesce with it, and serves as a replacement for lost or missing root of the tooth. Dental implants are an ideal option for patients with good oral hygiene that suffered the loss of teeth due to periodontal, teeth treatment failure, trauma or any other reason. The look and feel of a patient with implants is identical to that of natural teeth. Since the implant is firmly combine with jaw bones are prevented bone loss and gum recession that often occur in dental bridges and dentures below. No one will be able to notice that you have an artificial dental restorations.
IMPLANT SUPPORTED DENTURE
The defects of alveolar jaw bone continuation, usually, resulting from bone resorption due to inflammation around the tooth root or the result of bone loss during a tooth extraction or trauma. Often the places are ideal for implants with the static aspects of planning and optimal scheduling for later prosthetic care. In cases where it is not possible to achieve primary stability of implants in alveolar bone above or below the defect, filling defect is indicated transplantation bone or deputies of the natural bone, and implantation is delayed for at least six months. Procedure like this increases bone volume in all dimensions, width flap must be immobility by cutting the peritoneum in order to, without tension, ears for the palatal side of the cut. When reconstruction of the defect, is intended to compensate the height of alveolar bone, bone transplants should be applied in the form of blocks.This kind of transplant should be covered with commercial Absorber membrane or as a free peritoneum flap. By applying the membrane, preventing the ingrowths of soft tissue through existing cavities between the granules in any way the bone surface becomes smooth and separates easily and peritoneum in the second act at the time of implant installation. When the bone defect filled with granules and does not cover the membrane, granules tend migration through the peritoneum, even in the lining, which makes it difficult abruption peritoneum at the time of implantation.
By lifting flap, round drill is use to remove the cortex in the projection of mandibular canal in the desired segment. One part of the groove created in the cortex, the curette removed spongiose part of bone to content channels. Suitable instrument, the "sixes" or narrow curette, which is introduced into the channel between the beam and neurovascular spongiose, protects the nerve from possible damage during the final drill to remove bone lateral mandibular canal wall. Neurovascular bundle is, curette, and separated from the mandibular canal walls and move laterally in order to create space for the safe installation of implants. After implantation, neurovascular bundle is allowed to passively snaps into implants.
LATERALISATION OF INFERIOR DENTAL NERV
When the height of alveolar bone in the area of the maxillary sinus is less than 10 mm, it is usually indicated some of the methods of "raising" the floor of the maxillary sinus in order to avoid undesirable penetration and perforation of the mucous membranes in the sinus cavity of the implant. The literature uses the term "sinus lift" for most surgical techniques. Raising the floor of the sinus can be done in several ways depending on the amount of alveolar bone.
