Maxillary Sinus Floor Augmentation Using Blood Without Graft Material. Preliminary Results in 10 Patients

Objective This study aimed to systematically review the available literature on the treatment of patients with juvenile idiopathic arthritis (JIA) with temporomandibular joint (TMJ) involvement. Study Design According to the PRISMA statement (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, studies were included until August 2012. Results A total of 40 articles were identified. TMJ involvement in patients with JIA varies between 17% and 87%. The mean age at diagnosis of JIA is 7.2 years. TMJ treatment can be divided into 2 main groups, an arthritis group and a dentofacial deformity group. The main treatment modalities are counseling, pharmaceutical interventions, physiotherapy, orthodontic treatment, surgery, or a combination of the aforementioned therapies. Conclusions TMJ involvement in patients with JIA has a high incidence. There is no consensus on the treatment of TMJ pathology and dentofacial deformities in patients with JIA, and treatment varies from counseling to surgery. Treatment to improve aesthetics and function and to obtain pain reduction can be effective. However, the articles are heterogeneous, and the level of evidence is low (level IV).

Treatment management of children with juvenile idiopathic arthritis with temporomandibular joint involvement: a systematic review.

Purpose The aim was to determine the survival rate of dental implants installed in the posterior region of the maxilla after a graftless maxillary sinus lift via the lateral window approach and to identify the factors involved in the results. Materials and methods A systematic search was done on MEDLINE, EMBASE, LILACS, Scopus, and Science Direct up to June 2016; additional studies were identified through an analysis of references. Primary studies in English, Spanish, Portuguese, and French were included; the selection and data extraction process was conducted by 2 investigators independently, and the methodological quality was evaluated by means of the Effective Public Health Practice Project's Quality Assessment Tool. Results The combined search identified 232 articles. After the selection process, 11 articles were identified, 9 of which were prospective and 2 were retrospective. In all of them, the graftless maxillary sinus lift was done with the immediate installation of the implant. All the studies included presented a low methodological quality. The mean survival rate of the implants was 97% with an average new intrasinus bone formation of 6.2 mm. Conclusion This technique has a high implant survival although it is not possible to identify its correct indication and contraindication.

Graftless Maxillary Sinus Lift Using Lateral Window Approach: A Systematic Review

RESUMEN: Los procedimientos quir urgicos que envuelven la rehabilitaci on de la regi on maxilofacial requieren frecuentemen-te el uso de injertos para la reconstrucci on de de deformidades cong enitas o adquiridas. De esta forma, defectos oseos pueden clasificarsecomo cr iticos o no cr iticos. En esta investigaci on fueron utilizados 6 canes machos realizando 2 defectos bicorticales de 8mm de di ametroen la calota craneal de cada animal; el relleno de las cavidades se realizo como grupo 1 con coagulo sanguineo y grupo 2 con huesoautogeno en particulas. A trav es de un an analisis histologico descriptivo se observo en el periodo de tres semanas de sacrificio que elgrupo 2 fue el unico en presentar regiones de aposicion de nuevo tejido oseo. En el periodo de 6 semanas el grupo 2 presento part iculasde hueso autogeno utilizadas para el relleno en estado de reabsorcion avanzada en ausencia de los bordes nitidos entre el defecto y elhueso preexistente. De este modo se concluye que el metodo que auxilie en el proceso de reparacion tecidual como los injertos oseosautogenos, estan indicados en la recuperacion de defectos criticos, iguales o mayores que 8mm.

RESUMEN: Las fracturas orales y maxilofaciales representan un 6% a 8% de las fracturas oseas corporales. Estas lesiones sonde complejo manejo y exigen un diagn ostico precoz, certero y preciso. El Hospital Regional Hern an Henriquez Aravena, de la ciudad deTemuco, no posee cirujanos orales y maxilofaciales en los equipos de urgencia inmediata, de forma que los ingresos son realizados porotros profesionales.En un ano de seguimiento se realizaron 34.931 consultas medico-legales en el Servicio de Urgencia del Hospital RegionalHernan Henriquez Aravena. De esas consultas se escogio una muestra representativa de 742 sujetos de quienes se obtuvo informaciongeneral y de las lesiones en particular. Se obtuvo tambien asociacion estadistica mediante la prueba Chi – Cuadrado.Seis porciento de las consultas en el Hospital Regional Hernan Henriquez Aravena fueron asociadas a fracturas maxilofaciales,donde el grupo con mas consultas fueron el de los menores de 20 anos. Del total muestral, el 64.4% correspondio a sujetos del sexomasculino, manteniendo una relaci on hombre:mujer de 3.1:1; sin embargo, esta relaci on aumento su diferencia en sujetos mayores de 15anos. El 31.1% de las consultas fueron causadas por agresiones, mientras que 24.4% fueron asociadas a las ca idas. La principal zona defractura fue el complejo orbito-naso-etmoidal con un 55.6% y las fracturas dentoalveolares con un 22.2%. Existi o asociaci on estad isticamentesignificativa entre edad, sexo, agresion, fracturas mandibulares y fracturas dentoalveolares (p < 0.05).Los datos reflejan la alta prevalencia de fracturas maxilofaciales en la comuna de Temuco, Chile, siendo similar a lo que ocur reen otras partes del mundo. El grupo de los j ovenes es el de principal consulta donde las agresiones juegan un papel fundamental. Con elpresente estudio descriptivo creemos que se justifica plenamente la presencia de cirujanos orales y maxilofaciales en los equipos deurgencia del Hospital Regional Hernan Henriquez Aravena, Temuco, Chile.
