DENTAL IMPLANTS

WHAT DOES The IMPLANT?
The implant is the branch of dentistry that deals with replacing missing teeth with artificial roots anchored to the bone that can support individual teeth, groups of teeth or can act as a stabilizing support for a full denture Mobile.

The plant is not more than a titanium screw, a highly biocompatible metal that does not cause reactions of foreign body rejection but establishes a direct connection with the bone which is the basis of the host integration in only 6 months; therefore the material implant is an important element in achieving integration between bone and implant.
In the rehabilitation performed by implants, the implant unit must be considered as a substitute of the dental root.

From an aesthetic point of view-prosthetic implants are arranged so as to obtain an optimum result from the treatment. We must also consider the degree of bone resorption and other anatomical features.
Capacity utilization provides a viable alternative to traditional dentures, allows us to restore the smile in a more natural, totally biocompatible materials, offers the possibility to get a tooth fixed even if you have more natural teeth and allows to rehabilitate the edentulous (for the lack of teeth) while preserving the adjacent teeth without limarli to insert bridges.
Because of the characteristics of biocompatibility and the high success Aesthetic and Functional we get the resolution of many problems prosthetic.

WHO CAN ‘MEETING The IMPLANT?
The implant can be addressed by a large number of patients, practically almost everyone. You have to assess the general health, bone available and its quality, the clinician evaluated by means of the “dental scan” (three-dimensional X-ray of the mandible and maxilla) and the motivation of the patient to maintain good oral hygiene.
There are cases, where, unfortunately, is not recommended to the patient implant therapy.
For example, it is not advisable to undergo the therapy if the patient goes through a period of great physical and psychological stress, or during pregnancy.
You can not make these interventions are in place if anticoagulants or immunosuppressive drug treatments. Anemia, impaired defenses against infections and other problems of coagulation and also juvenile diabetes are absolute contraindications to implant. In the case of cardiovascular disease in patients with prosthetic heart valves and previous bacterial endocarditis, there are high risks should be assessed in the treating cardiologist. Even in the case of special bone diseases must carefully consider the pros and cons of any implant therapy.

QUANTITY ‘BONE
The availability bone in the area toothless in which it is expected the insertion of implants, it is of utmost importance regardless of the implant system you want to use. Using the current diagnostic tools (x-rays, dental scan, etc..) Can be evaluated with sufficient accuracy the size and shape of the bone along with the anatomical relationships with facilities especially important.

In case of insufficient bone or gum can replace missing tissues with sterile materials and totally biocompatible.

STEPS IMPLANT
The first phase consists of a therapeutic detailed interview with the patient during which he is provided with clear information about his situation with dental indication of the various treatment options and the risks involved. The patient must make themselves fully aware of the importance and the possible consequences of the intervention.

If the patient agrees, and unless there are contraindications itself is inserted in the mandible or jawbone under local anesthesia.

The procedure lasts about 20-30 minutes for each implant inserted unless complications and is not painful during its course. In the healing phase may be a slight pain and a slight swelling (such as after extraction) The intervention is preceded and followed by drugs, at the discretion of the dentist or health care professional, including antibiotics and anti-inflammatory agents are included for avoid infection and excessive post-operative discomfort.
According to the traditional method are expected from 3-4 to 6 months depending on the location of the plants, before proceeding to the second stage surgery which consists in connecting a “healing abutment” implant. Soon the healing abutment is replaced with an abutment screw which forms the first support for a temporary crown, and only then for a final crown (PHASE PROSTHETIC).

IN THE ABSENCE OF BONE, WHAT TO DO?
The maxillary sinus is a cavity which is located in the bone maxilla, below the zygomatic bone (see illustration here to the left). Its function is to lighten the weight of the bones of the skull, is connected to the nasal cavity and is coated with a thin mucous membrane.
Natural in anatomy, the maxillary sinus extends down to the roots of the premolars and molars, as long as these teeth are present.

WHY ‘AND’ SHOULD THE sinus lift?

The extraction or loss of the premolars and molars often cause, within a few months, a process of bone resorption, which served as a support for the root of the tooth, in this way, the maxillary sinus extends downward. The result is that the jaw bone is too thin to place an implant, because the implant thread would fall “in a vacuum” of the maxillary sinus and would not be sufficiently anchored to the bone.
   
The surgical technique has solved the problem with an operation that involves the dissection of the thin membrane, so as to raise it upwards and fill of synthetic bone part of the maxillary sinus that will subsequently be used for the insertion of an implant. In fact, after a few months, the synthetic bone is colonized by cells of the bone of the patient and you get a bone suitable for insertion of an implant, which thus receives sufficient height to be firmly anchored to the bone structure.

The sinus lift can be performed with two very different techniques: the great rise and minirialzo of the maxillary sinus.

BIG sinus lift:
The sinus lift can be performed with two very different techniques: the great rise and minirialzo of the maxillary sinus.
 
This technique is expected to open a trap door side into the bone of the maxillary sinus, for access to the membrane, this is first unglued laterally, then with a tool inside the lifting passing below.
 This procedure presents a series of drawbacks: first, the operation is rather long and complex, which involves a high cost and requires the recruitment of many drugs (antibiotics, anti-inflammatories, painkillers and cortisone) for a considerable period of time; also there is a fair risk of tearing the thin membrane of the breast, which involves in some cases failure of the intervention; finally not underestimate the fact that in many cases after the intervention occurs a very marked swelling in the face, often accompanied by pain for about 3-6 days, depending on the case. It must not be forgotten that often you can not place implants in the same operation, but you have to wait 6 to 10 months before you proceed with a second operation for implant (you must then wait another 3-4 months before mounting the definitive crowns).

MINI LIFT in the maxillary sinus:
 
This technique is only used to place dental implants.
The minirialzo of the maxillary sinus is a delicate operation, simple and above all comfortable for the patient does not cause swelling, or pain in the days following surgery. Depending on how many implants require, you make small holes up to the sinus membrane: do not run the risk of tearing because the drills used are rounded at the tip and can not cut the soft tissues, and when he reaches the membrane, with a special plunger pushes the filling material that gradually dissected the membrane without risk and raises to the height needed to place implants. In this way it is often possible to place implants already in the same session, thus avoiding a second surgery and dramatically speeding healing time (generally from 4 to 8 months depending on the case against the 6-14 months required by the procedure of great rise in two surgery).
