Abstract(s)
Atualmente os avanços na área da implantologia têm revolucionado a reabilitação estética e funcional de áreas edêntulas, incluindo o desafio específico representado pela reabsorção óssea no maxilar superior.
Após a extração dentária, ocorre um processo fisiológico de remodelação no osso alveolar, resultando na redução das dimensões da crista óssea. Essa reabsorção óssea é ainda mais acentuada no maxilar superior, podendo ser agravada pela pneumatização do seio maxilar, o que reduz significativamente o volume ósseo disponível para a colocação de implantes. Além disso, doenças periodontais graves, traumas e a falta de estímulo nos tecidos ósseos também contribuem para a atrofia maxilar superior.
Contudo, uma solução eficaz para contornar essas limitações tem se destacado: os implantes Pterigóideos. Estes implantes representam uma alternativa para a reabilitação de pacientes com atrofia maxilar superior severa. Colocados através da tuberosidade maxilar, são fixados no processo pterigóide do osso esfenóide e no processo piramidal do osso palatino.
Os implantes Pterigóideos oferecem uma ancoragem sólida e estável, permitindo a reabilitação oral nestes casos desafiantes. Além disso, eliminam a necessidade de enxertos ósseos, reduzindo o tempo de cicatrização, a morbilidade e o custo do tratamento. Esta abordagem inovadora tem sido relatada na literatura com taxas de sucesso notáveis, proporcionando aos pacientes uma solução segura e eficiente.
Os implantes Pterigóideos permitem assim, ao médico dentista superar as limitações impostas pela reabsorção óssea no maxilar superior. Esta técnica oferece a oportunidade de restaurar a função mastigatória, a estética e a qualidade de vida dos pacientes que enfrentam edentulismo e atrofia maxilar.
Currently, advances in implantology have revolutionised the aesthetic and functional rehabilitation of edentulous areas, including the specific challenge posed by bone resorption in the upper jaw. After tooth extraction, a physiological process of remodeling occurs in the alveolar bone, resulting in a reduction in the dimensions of the bone crest. This bone resorption is even more pronounced in the upper jaw and may be aggravated by the pneumatization of the maxillary sinus, which significantly reduces the bone volume available for implant placement. Moreover, severe periodontal diseases, trauma and the lack of stimulation in the bone tissues also contribute to upper jaw atrophy. However, an effective solution to circumvent these limitations has stood out: pterygoid implants. These implants represent a viable alternative for the rehabilitation of patients with significant upper maxillary atrophy. Placed through the maxillary tuberosity, they are fixed into the pterygoid process of the sphenoid bone and the pyramidal process of the palatine bone. Pterygoid implants provide a solid and stable anchorage, enabling oral rehabilitation in these challenging cases. In addition, they eliminate the need for bone grafts, reducing healing time, morbidity, and cost of treatment. This innovative approach has been reported in the literature with remarkable success rates, providing patients with a safe and efficient solution. Pterygoid implants thus allow the dentist to overcome the limitations imposed by bone resorption in the upper jaw. This technique offers the opportunity to restore masticatory function, aesthetics, and quality of life for patients facing maxillary atrophy.
