Hospital Intervention in Severe Sinus Infection After Bone Graft.

This study presents the case of a patient who required antrostomy under general anesthesia to treat a sinus lift complication. The patient was a 43-year-old woman with no systemic abnormalities who underwent maxillary sinus lift surgery associated with mineralized bovine bone graft. The Schneiderian membrane was perforated during the procedure, and the rupture was treated with collagen membranes to close the wound and contain the biomaterial, preventing its dispersion. The patient developed a maxillary sinus infection 7 days after surgery. This infection was initially treated with 875 mg amoxicillin combined with 125 mg clavulanic acid. Although the initial infection did not worsen, the patient developed maxillary sinusitis. Thirty days after the onset of the initial infection, the patient underwent an intraoral surgery under local anesthesia to remove the biomaterial and clean the sinus cavity. Despite this procedure, maxillary ostial patency was still compromised, and antrostomy was performed endoscopically in a hospital setting under general anesthesia. This procedure resolved the sinus infection. Then, 12 months after hospitalization, the patient was treated with another sinus graft surgery without postoperative complications. The treatment of sinus infections caused by the graft surgery may require early and active intervention with antibiotics, graft removal, and antrostomy to prevent major complications.

Osteogenesis imperfecta type III: Oral, craniofacial characteristics and atypical radiographic findings oral.

Osteogenesis imperfecta (OI) is a disease characterized by decreased bone mineral density, causing susceptibility to bone fractures by mild trauma and bone deformities. The aim of this study was to describe an osteogenesis imperfecta type III clinical case, its craniofacial and oral changes as well as its atypical radiographic findings. An eighteen-year-old, male patient diagnosed with osteogenesis imperfecta type III was referred for dental evaluation; the clinical examination showed the craniofacial and oral changes of the disease such as triangular face, class III malocclusion, anterior open bite and posterior crossbite, dentinogenesis imperfecta presenting amber discoloration. The radiographic examination revealed teeth with pulp chamber obliteration and root canals, however unusual findings were also observed such as: bilateral increase of the mandibular canals and preservation of the pulp chamber and third molar root canals. Our findings show that is essential an adequate knowledge of anatomy, a careful anamnestic evaluation and a complete radiological evaluation of the patient with OI. Key words:Dental anomalies, developmental disability, rare disorders.

Tomographic Analysis of the Impact of Mandibular Advancement Surgery on Increased Airway Volume.

PURPOSE: This study aimed to quantify, using cone-beam computed tomography (CBCT) in patients who underwent a mandibular advancement surgery associated with genioplasty, three-dimensional changes in airway space and to evaluate whether these changes differ between men and women. MATERIALS AND METHODS: Preoperative and 8-month postoperative CBCT scans of 38 patients aged 18-45 years of either sex and any ethnicity who underwent mandibular advancement surgery associated with genioplasty were analyzed using the Xoran software (Xoran Technologies, Ann Arbor, MI, USA). The linear distances gonion-gnathion (Go-Gn) and condylion-menton (Co-Me) were obtained. Airway volume was measured using the Dolphin Imaging software, version 11.0. Then, data were tabulated and analyzed using Student's t-test. RESULTS: Mean patient age was 30.3 years; 39.47% were men and 60.63% were women. The mean Go-Gn distance was 72.05 mm before surgery and 78.56 mm after surgery, with a mean gain of 6.51 mm. The mean Co-Me distance was 113.47 mm before surgery and 119.89 mm after surgery, with a mean increase of 6.42 mm. Both differences were statistically significant. The mean volume of airway space was 17,272.92 mm3 before surgery and 24,173.74 mm3 after surgery, with a statistically significant mean increase of 6900.82 mm3. There was no statistically significant difference in mean volumetric gain between men (7566.69 mm3) and women (7456.69 mm3). CONCLUSION: Mandibular advancement surgery results in significant increase of airway space, and there is no difference in airway volume between men and women.

Computer guided surgery in the maxillary esthetic zone / Cirurgia guiada por computador em área estética da maxila

ABSTRACT This clinical report describes the implant rehabilitation for the treatment of pathological roots resorption due to inadequate orthodontic movement in prosthetic space reduced by means of load and immediate implants, computer-guided surgery and use of the own tooth crown in a 21-year-old-patient. The atraumatic exodontics of the right and left upper lateral incisors was performed, and then immediate placement of osseointegrated implants using the computer guided surgery technique. The crown teeth itself was used in the immediate aesthetic and functional rehabilitation. Completion of the treatment resulted in a functional and aesthetic successful outcome and a 27 months follow-up presented uneventful. The procedures included in this complex rehabilitation treatment in the esthetic zone were appropriate and essential for the maintenance of the soft and hard tissues contour and thickness ensuring the excellence in rehabilitation.

RESUMO Este relato de caso clínico descreve a reabilitação com implantes para o tratamento da reabsorção radicular patológica devido à movimentação ortodôntica inadequada em espaço protético reduzido, por meio implante imediato e carga imediata, pela técnica da cirurgia guiada por computador e uso da própria coroa dentária, em paciente de 21 anos. A exodontia atraumática dos incisivos laterais superiores direito e esquerdo foi realizada, em seguida realizou-se a instalação imediata dos implantes osseointegráveis, utilizando a técnica de cirurgia guiada por computador. Os próprios dentes da coroa foram usados na reabilitação estética e funcional imediata. A conclusão do tratamento resultou em sucesso funcional e estético com acompanhamento de 27 meses sem intercorrências. Os procedimentos incluídos neste complexo tratamento de reabilitação na zona estética foram adequados e essenciais para a manutenção do contorno e espessura dos tecidos moles e duros garantindo a excelência na reabilitação.
