“…Advancement in the progress of implants suggested that the reverse zygomatic implant appears to hold promise as a useful addition to the implant arsenal for the treatment of maxillectomy patients [13]. Literature suggests that the atrophic bone contents induce no osseointegration with zygomatic implants, leading to periimplantitis and complications [14][15]. Some of the surgical placement complications of the pterygoid implants reported in the literature include minor venous bleeding, minor trismus, implant displacement, and a unique case of continuous pain and discomfort [16][17][18].…”

Maxillofacial defects and their rehabilitation are a major concern in this socially productive era. The rehabilitation of these massive defects in the oral and maxillofacial region poses a challenge to the prosthodontist in terms of selection of material, retentive aids, the adaptive capability of the patient, and cost. This case report describes the management of the midfacial defect involving the orbit, zygoma, maxilla, and their soft tissue counterparts with a removable silicone extraoral compartment and an acrylic intraoral compartment, which are retained with strong cobalt samarium magnets, an elastic loop around the occiput, and spectacles. The maxillofacial prosthesis fabricated for this patient restored the patient's facial esthetics, speech, dental articulation, lip support, mastication, and anterior maxillary seal.

“…Apart from this, there are certain complications associated with the placement of zygomatic implants, such as orbital injury/penetration, oroantral fistula formation, sensory nerve deficits temporarily, and vestibular cortical fenestration [ 18 ]. To overcome these complications, it is important to plan the placement of the implant based on a CT/CBCT imaging, and the skill of the surgeon plays a crucial role.…”

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.

“…No entanto, as compli-cações dos implantes zigomáticos, sendo a sinusite a mais comum, podem ser difíceis de manejar, resultando na perda do implante. Assim sendo, a escolha da reabilitação por meio de implantes zigomáticos deve ser definida de forma seletiva, a fim de minimizar as possíveis complicações 23 .…”

Maxilas severamente atrofiadas representam um desafio às reabilitações implantossuportadas. A reconstrução maxilar com enxertos ósseos para permitir a reabilitação com implantes osseointegrados é um tratamento com boa previsibilidade e alto índice de sucesso. No entanto, a morbidade causada pela necessidade de regiões doadoras e grande quantidade de osso dificulta a aceitação dos pacientes; podendo, inclusive, ser contraindicada dependendo da condição sistêmica. O objetivo deste trabalho é revisar a literatura, discutir as indicações, complicações, previsibilidade das reabilitações com implantes zigomáticos, assim como relatar um caso. Os implantes zigomáticos surgiram como uma alternativa para a reabilitação de pacientes maxilectomizados, decorrente da exérese de tumores. Contudo, a técnica foi extrapolada para os casos de atrofia óssea severa, como abordado no caso em questão, e perdas ósseas decorrentes de infecções ou traumas, diminuindo o tempo e a morbidade do tratamento, quando comparada à reconstrução óssea. A reabilitação com implantes zigomáticos pode apresentar complicações, como o mau posicionamento dos implantes, comprometendo a reabilitação; todavia, apesar das restrições da técnica, a literatura mostra que os implantes zigomáticos, quando bem indicados, representam uma boa alternativa para a reabilitação de maxilas severamente atrofiadas.
