An osseointegrated implant is an artificial element that is placed into the jawbone in order to restore missing teeth and that osseointegration. Osseointegration is defined as the direct binding, both functional and structural link between the living bone and implant surface under load.
Osseointegrated implants are indicated in cases of partial and complete desdentación. There are few absolute contraindications considered for the use of implants such as pregnancy, granulocytopenia, corticosteroids maintained, uncontrolled diabetes, hemophilia, osteoradionecrosis, chronic renal failure, etc..
Not all patients can receive osseointegrated implants.
A good history and a thorough examination and radiological orofacial are essential before starting the technique of implant placement.
Most of the techniques has a first-stage surgery consisting of insertion of the implant looking at four key principles:
* Infertility, osseointegrated implants
* Milling careful
* No pollution, and
* Initial implant stability.
The second surgical stage is performed once the time has elapsed (months) for osseointegration to occur, and it proceeds to the connection of transepithelial abutments. Once the healing is at the moment in which the implant is ready to begin the placement of the prosthesis.
Complications are rare and are divided into immediate and mediate (secondary or delayed).
Immediate complications include: bone fractures, tuberosity, sinus or nasal floor or mandibular, lacerations, bleeding, soft tissue injuries, nerve injuries, displacement of the implant, submucosal emphysema, broken instruments, broken fillings, or dentures neighboring and so on.
Mediate complications include: infections (osteitis, abscess, osteoradionecrosis, cellulitis, trismus, sinusitis, etc.), hemorrhagic (local or general cause), mucositis and peri; general (bacteremia, sepsis, glomerulonephritis, or hyperthyroid hyperglycemic crisis, decompensated heart, hepatitis, etc).
