RESUMO
O objetivo desta revisão foi atualizar o conhecimento básico sobre medicações antiangioênicas e antirreabsortivas, além dos bifosfonatos, e discutir condutas clínicas, protocolos de tratamento e gerenciamento da osteonecrose que podem ser adotados para benefício dos pacientes na Implantodontia. Devido à ocorrência de novos casos de osteonecrose após o uso de medicações antiangiogênicas e antirreabsortivas, a American Association of Oral and Maxillofacial Surgeons (AAOMS) sugeriu a mudança de nomenclatura Bronj (Bisphosphonate-related osteonecrosis of the jaw) para MRONJ (Medication-related osteonecrosis of the jaw). O tipo de medicação e a indicação da mesma (câncer, mieloma múltiplo, osteoporose/osteopenia) devem ser levados em consideração no manejo dos pacientes. Há controvérsias sobre a suspensão das medicações (Drug Holiday) e testes que predigam o risco de MRONJ. Novas pesquisas realizadas em cobaias procuram determinar o efeito do alendronato ministrado sistemicamente, após a cirurgia, sobre a osteointegração de implantes, neoformação óssea e reabsorção de enxerto ósseo. Outra abordagem de pesquisa sobre bifosfonatos aplicados sobre a superfície dos implantes, com o objetivo de melhorar a osteointegração, está sendo realizada em humanos e em cobaias. A constante atualização dos profissionais de saúde se faz necessária para tratamentos mais eficientes e com menor risco aos pacientes.
ABSTRACT
The objective of this review is to update the basic knowledge about antiangiogenic and antiresorptive medications, in addition to bisphosphonates and discuss clinical procedures, treatment protocols and management of osteonecrosis, which can be adopted for the benefit of patients seeking dental implant treatment. Due to the occurrence of new cases of osteonecrosis after using antiangiogenic and antiresorptive medications, the American Association of Oral and Maxillofacial Surgeons (AAOMS) suggested changing Bronj nomenclature (Bisphosphonate-related osteonecrosis of the jaw) to MRONJ (Medication-related osteonecrosis of the jaw). The type of medication and treatment indications (cancer, multiple myeloma, osteoporosis/osteopenia), should be taken into consideration for patient management. There is controversy about the suspension of medications (Drug Holiday) and tests to predict the risk of MRONJ. New animal model studies try to determine the effects of alendronate as systemically administered, after implant surgery, on bone formation and bone graft resorption. Other studies at human and animal investigate the role of bisphosphonates as biological coatings at implant surfaces to improve osseointegration. Continuing dental education is mandatory to provide more efficient treatments with less risk to patients.
