• Resumen

  • This article aspires to show that pterygoid implants are a magnificent and viable alternative to other posterior implants of the maxilla, especially in cases of atrophy.

    This study is based on a retrospective analysis of pterygoid implant data from 2003 to 2023, recollecting the following variables: year of placement, location, shape of the implant, diameter of the implant, length of the implant, torque of the implant, whether or not it was post-extraction, whether or not there was immediate loading, whether or not smoking was present (smoking habit), the brand of the implant and the success/survival or failure/non survival of the implant.

    The total of 178 pterygoid implants placed in the 113 patients eligible for the study was analysed by subgroups, with percentage of global success of 98.3% (3 failures).

    Pterygoid implants offer biomechanical and success/survival characteristics similar or superior to the so-called conventional implants and avoid a series of surgical and prosthodontic procedures more difficult than the ones required by other implants in many occasions.
