• Abstract:

  A moderately to severely resorbed maxilla represents a challenge for functional occlusal rehabilitation, especially in cases arising from local infections, severe bone resorption or surgical treatments for oncological resection. Given the adversities of the techniques previously recommended, it was necessary to present an alternative that included the patient's rehabilitation capacity without major side effects. Thus, an alternative found was the All-on-four technique, which consists of placing four implants anchored in noble structures forming a polygon and a splinted prosthesis on top. A clinical case report of an All on four surgery was carried out. Patient JMS, 74 years old, Caucasian, completely toothless at the age of 22 due to car trauma, sought the clinic for dental implant treatment in search of undergoing superior protocol surgery. Serological tests were requested prior to surgery and computed tomography of the jaw. After the pre-surgical medication protocol, local anesthesia was performed with vasoconstrictor, relaxing incisions in the distal and midline for the total folding of the periosteum, instrumentation kit and implants NEODENT Alvim 3.5x 16mm, and Alvim 3.5 x 13mm all with locking greater than 60N and with universal transmucosal of 1.5mm straight anteriorly and 30 degrees posteriorly. The patient's complete denture was captured with metal braces and self-adhesive acrylic resin. It is concluded that All on four surgery in atrophic jaws with conventional implants has great predictability, being a differentiating proposal from maxillary sinus grafts and zygomatic implants.
