USINAGEM EM IMPLANTES ZIGOMÁTICOS E REABILITAÇÃO ESTÊTICO-FUNCIONAL EM PACIENTE PSEUDO CLASE III: RELATO DE CASO

The rehabilitation of atrophic jaws represents a complex challenge, leading to the search for innovative approaches. Conventional procedures, such as sinus lifts, have limitations, driving interest in zygomatic implants. However, complications persist, especially in areas of pronounced concavity. This case report aims to demonstrate the effectiveness of an innovative surgical approach, combining zygomatic and transnasal implants, to overcome anatomical limitations and achieve satisfactory aesthetic and functional results. A 58-year-old female patient, completely toothless, underwent rehabilitation at the Instituto Rosenvaldo Moreira, due to pronounced maxillary atrophy. Two treatment plans were proposed, involving zygomatic and transnasal implants. The surgery, performed in an outpatient setting under intravenous sedation and local anesthesia, included the sequential installation of transnasal and zygomatic implants, with special attention to machining the cervical third to prevent complications. The surgical approach used, combining zygomatic and transnasal implants, proved to be effective in the rehabilitation of the atrophic maxilla. Careful machining helped to avoid complications, demonstrating stability and absence of peri-implant inflammation in the one-year follow-up. This report offers a valuable contribution, highlighting the feasibility and success of this innovative approach in challenging situations of maxillary atrophy in implant dentistry.
