RESUMO
O objetivo deste estudo foi avaliar clinicamente a taxa de sucesso de dois implantes com diferentes tipos de tratamento de superfície em maxilas com reconstrução óssea prévia. Foram selecionados dez pacientes. Maxilas altamente reabsorvidas (2 mm de altura e espessura) receberam enxertos da crista ilíaca em bloco para aumento lateral, sendo parte triturada e colocada no seio maxilar para aumento vertical. Implantes convencionais com superfície lisa (n = 38) e TiUnite MKIII com superfície rugosa (n = 38) foram instalados cinco meses após os enxertos usando-se uma técnica cirúrgica modificada. Após cinco meses, procedeu-se a reabertura e o teste de torque para verificar a estabilidade dos implantes. Um implante em cada grupo foi perdido. A taxa de sucesso para cada tipo de superfície foi de 97,4%. Todos os enxertos mostraram 100% de sucesso.
ABSTRACT
The aim of this study was to clinically evaluate the success rates of two different implant surfaces in bone-grafted maxillary arches. Ten completely edentulous patients were selected. Highly resorbed maxillae (2 mm in height and widht) received iliac crest bone block grafts for lateral augmentation, being that some material was morselized and packed into the maxillary sinus for vertical augmentation. Standard, machined (n = 38) and TiUnite MKIII rough-surface (n = 38) dental implants were placed five months meses after grafting procedures according to a modified surgical technique. Then, five months later, second-stage procedures and torque tests were performed to verify implant stability. One implant was lost in each group. Individual success rates were of 97.4%. Bone grafts demonstrated 100% of success.
