Expansão cirúrgica do rebordo alveolar por osseodensificação, regeneração tecidual guiada com implante fabricado por manufatura aditiva e cirurgia plástica periodontal na zona estética – relato de caso com dois anos de acompanhamento

RESUMO

Paciente do sexo feminino, com 28 anos de idade, apresentou-se à clínica odontológica com ausência do incisivo central superior direito. Após avaliação clínica e radiográfica detalhada, menos de 3 mm de espessura óssea remanescente foram detectados. Após a abertura do retalho de espessura total, os procedimentos de osseodensificação foram iniciados. Depois, um implante cônico feito por manufatura aditiva foi instalado, seguido pelo biomaterial ósseo particulado e colocação da membrana absorvível fixada ao cicatrizador, finalizando pela aplicação de um enxerto de tecido conjuntivo subepitelial. Quatro meses depois, uma restauração provisória foi confeccionada e procedimentos cirúrgicos plásticos periodontais foram realizados para nivelamento das margens gengivais. Após dois anos de acompanhamento, os tecidos moles e duros permanecem sem intercorrências.

ABSTRACT

A female, 28 years-old patient presented to the dental clinics with the lack of the right maxillary central incisor. Upon detailed clinical and radiographic exams, less than 3 mm of bone thickness were detected. After elevation of a full-thickness flap, the osseodensification procedures were initiated. Then, a tapered dental implant made by additive manufacturing was placed, followed by a particulate bone biomaterial and absorbable barrier membrane fixed by the healing abutment, ending the surgery with a subepithelial connective tissue graft. Four months later, a provisional restoration was fabricated and periodontal plastic surgical procedures were made to level the gingival margins. After two years of follow-up, the soft and hard tissues remain free of intercurrences.

Key words – Dental implants; 3D printing; Osseodensification; Bone regeneration; Esthetic zone.
