Dental implants

Définition

The dental implant is an artificial root made of titanium intended to be buried in the maxilla or mandible that secondary support a prosthetic element. Strengths The modern implantology was born in the 50's through the work of Professor Branemark on osseointegration. He had noticed in studies on bone marrow of rabbits and dogs as hollow titanium screws implanted in the bone were almost part of it. The principle of osseointegration was born. Systems and techniques could then develop. To make an overview of the implants, we must see the advantages, disadvantages, constraints, techniques and results. The indications for implants are most commonly replacing missing teeth: This can be to replace one missing tooth without being required to intervene on the adjacent teeth, as required for a conventional bridge. Implants can also be used to replace a denture with a fixed prosthesis. Impossibilities exist and must be rigorously eliminated. They can be medical: a field immunocompromised, a systemic disease, allergies major risk medical treatment (anti coagulant for example), certain heart conditions (heart valve), or progressive disease are absolute contraindications against . They are sometimes anatomical: quality of the gums, density and structure of the bone status of inferior alveolar nerve, sinus volume. Finally, they can meet the patient misunderstanding of the implications for monitoring, neglect, poor hygiene and low motivation are equally unacceptable. The pre-implant assessment involves a medical examination and a phase of radiology and fingerprints. All must contribute to ensure optimal results and that this amount of information that allows the practitioner to offer a specific solution, leaving it to the patient to give their "informed consent" full and total. Finally, be aware that interventions need to implant the practitioner with appropriate training for the patient and rigorous discipline. Technically, two solutions are currently available technology "Swedish" in two stages: the implants are placed into the bone "to nurse" for 3 to 6 months, leaving healing and osseointegration to take place. Secondarily, the implants are uncovered, a screw is in place: it is put into operation. If all is stable in the bone, the implant itself is then performed. The technique "Swiss". It is done in a while. The implants are placed in the bone but are not buried under the gum, the collar of the implant above. The prosthesis can be performed after the same period of osseointegration. The implant is an evolving science and recent advances have helped to provide a range of implants suited to anatomical conditions "difficult". Similarly, in addition to pure titanium implants, various alloys are being considered. Meanwhile, the use of periodontal tissue regeneration techniques has expanded the indications and increasing success. In short: The implant is a solution among other prosthetic solutions with advantages and disadvantages. It is the responsibility of the practitioner during his one dialogue with the patient to identify and propose the best solution to the particular case represented by the loss of teeth.
