ABSTRACT
A reabilitação de maxilas atróficas permanece como grande desafio ao cirurgião, mesmo nos dias atuais. Nos últimos anos, as fixações zigomáticas têm sido apresentadas na literatura como uma opção viável para o tratamento daqueles pacientes que apresentam severa atrofia do rebordo alveolar maxilar com extensa pneumatização dos seios maxilares e que não desejam se submeter a procedimentos reconstrutivos. Sendo assim, o objetivo do presente estudo é realizar uma breve revisão da literatura e avaliar retrospectivamente as complicações encontradas em 16 casos de implantes zigomáticos, em um período mínimo de 24 meses de acompanhamento. Os resultados mostram que o percentual de complicações foi de 50% e que o índice de sucesso no tratamento foi de 76%. A dor foi o tipo de complicação mais comum (30%), seguida pela não osseointegração (25%) e pela infecção (20%). Em conclusão, podemos afirmar que complicações podem ocorrer em qualquer fase do tratamento e podem ocasionar a perda dos implantes zigomáticos instalados, devendo o cirurgião estar apto a intervir no momento necessário.
The rehabilitation of atrophied maxillary arches stands is a great challenge to surgeons. In the last years, the zygomatic fixations have been presented in literature as a practicable option to the treatment of patients with severe atrophy, large pneumatization of maxillary sinuses, and avoiding reconstructive procedures. In this case, the aim of this study is to perform a brief literature review and retrospectively evaluate the complications found in 16 cases of zygomatic implants, with a minimum period of 25- month follow-up. The results show that the percentage of complications was 50%, and the treatment success rate was 76%. Pain was the most common complication (30%), followed by the lack of integration (25%), and infection (20%). In this way, we can affirm that complications may occur in any treatment phase with loss of the zygomatic implant installed, obligating surgeons to interfere in certain occasions

AIM: The purpose of this report is to present a case of surgical and prosthetic treatment of a woman with inflammatory fibrous hyperplasia (IFH) and her evaluation during a six month period. BACKGROUND: IFH is a benign pathology, prevalent in female patients, and principally associated with ill-fitting prosthetic devices in need of adjustment. It is common for patients to require surgical removal of the hyperplastic tissue and fabrication of a new prosthesis. CASE REPORT: A 55-year-old female with a history of smoking presented with a chief complaint of missing the scheduled adjustment of her maxillary complete denture and the presence of moveable tissue under the denture. Surgical excision of the hyperplastic tissue followed with fixation of the prosthesis for six months to guide the healing of the soft tissue and to reshape the contours of the maxillary supporting tissues. SUMMARY: Surgical removal of hyperplasic soft tissue is a routine procedure, and the fixation of the prosthesis for the support of tissue during healing improves intraoral conditions for the fabrication of a new prosthesis in the future.
