The Cortically Fixed at Once approach CF@O allows to fix cortical implants even in severely atrophic jaws. The specificity of this protocol is that no graft, no sinus lift and no nerve displacements are used. In this way severe atrophies may be rehabilitated within 10 days with a fixed denture.
When there is loss of teeth, atrophy of the alveolar processes occurs in a vertical as well in a horizontal plane.
The term ATROPHY is defined in the dictionary as a “wasting away”, a diminution in the size of a cell, tissue, organ or part. When this process starts, it continues throughout the patients life because of the lack of stimuli (disuse atrophy) seen on alveolar process of the jaws. Implant placement in severely atrophic jaws is especially challenging because of the poor quality and quantity of the future implant bed. Calvarial or iliac bone grafts, mental nerve displacement and sinus lift procedures are often used to overcome the initially unfavourable anatomical and mechanical conditions.
But despite acceptable success rates, these approaches involve unpredictable degrees of morbidity at the donor or recipient sites. Furthermore patients are sometimes reluctant to undergo such procedures. The Cortically Fixed at Once approach CF@O uses the remaining bone for fixing cortical implants. The specificity of this protocol is that no graft, no sinus lift and no nerve displacements are used. Specific implants plate shaped implants ranging in length from 41-43 mm are used in the extremely atrophic sectors to well manage these regions.
The high fatigue strength of these solid titanium implants without any welds or added parts is particulary indicated for mechanically demanding situations (the canine and zygomatic sectors of the maxilla) and the mandibular ramus.
In this way severe atrophies may be rehabilitated within 10 days with a fixed denture. The Cortically Fixed at Once protocol is appliable to edentulous maxillaes and mandibles, to unilateral edentulisme in maxilla and mandible to bilateral edentulism in maxilla and mandible.
