El edentulismo es la pérdida total o parcial de dientes de etiología cariogénica, periodontal, traumática. Las enfermedades sistémicas prexistentes deben estar controladas, previo a los tratamientos odontológicos, mejorando el pronóstico. Objetivo: restaurar estética, función, fonética en paciente geriátrico con patologías sistémicas preexistentes controladas aplicando protocolo de rehabilitación oral completa. Presentación del Caso: Mujer de 74 años con hipertensión y diabetes, medicación permanente Glucophage (Metformina) y Losartan (Hidroclorotiazida). Desdentado total superior, desdentado parcial inferior, clase I de Kennedy. Tratamiento en Fases. Fase I planificación en modelos de yeso, modelos virtuales. Fase II quirúrgica instalación de 6 implantes dentales NEODENT. La fase II quirúrgica, se realizó cirugía campo abierto técnica de colgajo en forma de U, se colocaron 6 implantes dentales diámetro 3,75 mm x 11,5 mm. Cono Morse Alvim (13 y 23) ,cuatro implantes de conexión cónica, i.e drive implants (14, 16, 24 y 26). Fase III rehabilitación oral mediante filosofía gnatológica. Endodoncias de dientes inferiores, carillas de disilicato de litio, coronas de metal cerámica con ataches ERA, prótesis parcial removible inferior. Fase IV ejecución de prótesis hibrida superior con abutments multiunit de diferente angulación. Conclusión: el enfoque multidisciplinario en el tratamiento de la cavidad oral en pacientes geriátricos con patologías sistémicas prexistentes, permitieron restaurar función, estética fonética en el paciente.

“…In the present case, since the hard palate was sectioned, the prosthetic rehabilitation was planned with an obturator supported by a zygomatic implant considering the age of the patient. The major advantage of these implants is that they eliminate the use of graft material and its associated infections [ 16 , 17 ].…”

Rehabilitation of Maxillary Defect Using Zygomatic Implant Retained Obturator

Tumors involving the hard palate, maxillary sinus, or nasal cavity require maxillectomy based on the extent of the lesion. Lack of these boundaries affects the speech, esthetics, and masticatory function. Prosthetic rehabilitation of these defects can be done utilizing zygomatic implants. This present case describes the use of a zygomatic implant to retain a maxillary obturator in a 22-year-old male patient following partial maxillectomy (Brown’s Class 2b) due to odontogenic myxoma. A surgical obturator was secured in position subsequent to the implant placement. Following the healing period, an interim obturator using heat cure acrylic was fabricated. Mechanical retention for the definitive obturator was obtained through the ball attachment suspended from the multiunit abutment of the zygomatic implant. The case was followed up closely for a year to evaluate the function of the prosthesis. The prosthetic rehabilitation not only promoted esthetics and function but also improved the patient’s quality of life.

“…Mittal et al suggested the use of single-piece zygomatic implants to provide retention and support for an acrylic resin obturator and to alleviate osteocutaneous grafting procedure in a large maxillary defect. 42 Limitations associated with zygomatic implants include unavailability of bone, restricted intra-operative vision, anatomic complexity and variability of zygoma bone. 43 Also, overloading leverage in large defects, overgrowth of local soft tissue preventing abutment connection, sinus infections, facial pain, damage to surrounding structures and positional errors can adversely affect the success rate.…”

Various techniques have been described to restore acquired maxillary defects. The aim of this paper is to review the contemporary treatment modalities that have been explored to rehabilitate and reconstruct partial or complete maxillectomy in dentulous and edentulous patients. MEDLINE/PUBMED search was conducted for dental literature published from January 2000 to December 2018. Literature study revealed various methods and materials used to treat patients with acquired maxillary defects. These include modifications in method and materials used for the fabrication of conventional obturators (using precision and semi-precision attachments, telescopic copings, magnets, silicone based materials, titanium and its alloys, PEEK, thermoplastic resin); implant-supported obturators supported on conventional, zygomatic and pterygoid implants using different attachments (ERA, magnet, bar attachment, locator, ball attachment); use of CAD/CAM technology for presurgical planning and fabrication of obturator prosthesis; surgical reconstruction with microvascular free tissue flaps; and bone engineering. Significant attention has been devoted to refining current methods and developing better methods to successfully rehabilitate maxillectomy patients. The use of osseointegrated implants, newer prosthesis materials, advanced laboratory procedures, inclusion of CAD/CAM technology, advances in surgical reconstructive techniques and tissue engineering has revolutionized the traditional treatment options.
