ABSTRACT
A reabilitação com implantes tem como desafio as limitações de quantidade e qualidade óssea, sendo necessárias técnicas cirúrgicas de enxerto ósseo, permitindo a instalação dos implantes convencionais. Para pacientes que preferem opções menos complexas e traumáticas, os implantes curtos são uma opção de tratamento menos invasiva e com boa previsibilidade. Porém, para o seu melhor desempenho, princípios biomecânicos devem ser empregados, como utilização de mesa oclusal reduzida, ferulização de implantes, conexão interna do tipo Cone Morse e plataforma Switching. O objetivo desse trabalho foi relatar um caso clínico de uma paciente que descartou a cirurgia de levantamento de seio maxilar, sendo então proposto o tratamento com a utilização de implante curto do tipo Cone Morse, em que foi realizado o planejamento reverso e o uso de princípios biomecânicos.
Rehabilitation with implants is challenged by bone quantity and quality limitations, being necessary surgical techniques for bone grafting that allow conventional implants installation. for patients who prefer less complex and traumatic options, short implants are a less invasive treatment option and has good predictability. however, for best performance, biomechanical principles should be used, such as use of reduced occlusal table, splinting implants, internal connection of the Cone Morse type and Switching platform. The aim of this study was to report a case of a patient who dismissed the maxillary sinus lifting surgery, so the treatment proposed was the use of short implant Cone Morse type, in which reverse planning was done with the use of biomechanics principles.

The aim of this observational study was to assess the degree of patient satisfaction toward implant-supported prostheses. A questionnaire was used with two scales (one consisting of detailed adjectival and the other of numerical responses) regarding chewing, esthetics, speaking, comfort and overall satisfaction. The scales were administered to a sample of 147 patients treated with implants and prostheses. The data were submitted to the Kappa statistic and the Chi-square test to analyze the association between dependent and independent variables. High degrees of satisfaction (greater than 91%) were found for all categories evaluated, regardless of gender, age, number of implants or type of prosthesis. “Comfort” was associated significantly with the number of implants (p = 0.038), and “speaking” was associated significantly with the type of prosthesis (p = 0.029). Positive agreement was found between the scales for all categories evaluated, without statistically significant differences regarding respondent preference (p = 0.735). Patients treated with implant-supported prostheses were highly satisfied with the treatment.

Propósito: el propósito de este estudio fue evaluar y comparar el rendimiento masticatorio de pacientes desdentados totales rehabilitados mediante (prótesistipo Ad-Modum y/o prótesis removibles convencional. Método: Se evaluaron24 pacientes divididos en 3 grupos de ocho pacientes. Grupo Ipacientes rehabilitados con prótesis Ad-Modum bimaxilar, Grupo IIpacientes rehabilitados con prótesis Ad-Modum inferior y prótesis total removible superior, Grupo III pacientes rehabilitados con prótesis total removible bimaxilar. Se solicitó a cadapaciente realizar 20 golpes masticatorios a una pastilla de silicona previamente estandarizada, a la muestra obtenida se le realizó tamizado múltiple y los resultados fueron procesados con la fórmula de obtención de rendimiento masticatorio propuesta por el protocolo de Edlund y Lamm en 1980. Resultados: Lospromedios de rendimiento masticatorio fueron: Grupo I(15,6 por ciento±3,4), Grupo II (4,3 por ciento±4,6), Grupo III (0,3 por ciento±0,7). Mediante test de Tukey se demostró que existendiferencias significativas entre el grupo I y II, pero no entre los Grupos II yIII. Conclusiones: El tratamiento con prótesis Ad-Modum bimaxilar logró elmejor rendimiento masticatorio entre los 3 tratamientos rehabilitadores evaluados, el tratamiento con prótesis total removible superior y Ad-Modum inferior fue más exitoso en términos de rendimiento masticatorio que el grupo rehabilitado con prótesis total removible bimaxilar. Los tratamientos con prótesis removible total convencional, no otorgan al paciente una óptima función masticatoria

The achievement of passive fit is an important prerequisite for the prevention of complications in full-arch screw-retained implant prosthesis. With cemented prosthesis, the cementation compensates for the discrepancies in the cast framework, but the lack of retrievability seems undesirable. The aim of this paper is to propose a modified screw-retained prosthesis design for complete arch implant fixed rehabilitation. A technique for the fabrication of a full-arch metal-resin implant-supported screw-retained prosthesis is described. Cementation of the framework to the abutments intraorally improves the passivity of fit of the prosthesis on the implants. Maintenance of screw-access channels in the final prosthesis ensures retrievability. The metal-resin design allows for easy repair and maintenance. The prosthesis is cost-effective compared to conventional options and can be employed as a viable treatment alternative when considering metal-acrylic resin complete arch fixed prosthesis.

Using implant to replace missing teeth is dependent on bone quality and quantity. One of the ways to achieve better bone quality and quantity is using grafts such as autogenos bone, Bioss and demineralized dentin. The aim of this research was to study the histomorphometric effect of demineralized dentin on increasing bone quantity and ossteointegration in tibia bone of rabbit. In this experimental study five white New Zeeland female rabbit were obtained and a 3.5 mm hole was created to insert implants. One implant was inserted in each tibia so each rabbit had two implants. A 6 mm defect was made at the distal of that hole. These defects contained two cortical layers. One of these defects was filled with autogenous demineralized dentin [ADDM] and the other one was left empty. Each defect was covered with collagen membrane. Rabbits were sacrificed in 3, 5, 7, 9, 11 weeks and two samples were obtained from each rabbit. The samples were decalcified, their implants were removed and send to laboratory for histologic and histomorphometric assessment. Histomorphometric evaluation showed equal bone to implant contact [BIC] in cortical layer in both groups. The mean BIC in bone marrow of experimental group was more than the control group in different weeks [Addm=%19, control=%0]. The mean surface of new bone within threads [NBT] in different weeks in ADDM group was greater than controls [ADDM=%35 control%23.6]. In this study histomorphometric ADDM caused new bone formation in bone marrow around implant and osteointegration was increased

El análisis prospectivo hasta 2 años de la evolución clínica y radiográfica en la colocación de implantes individuales en el sector anterior con restauración inmediata. Los pacientes fueron evaluados clínica y radiográficamente a uno, tres y seis meses. El reporte preliminar a 6 meses demuestra que los implantes están oseointegrados. Se han medido los grados de reabsorción ósea por mesial y distal como criterio de evolución de la terapia. Después de 6 meses el cambio en los niveles de tejido óseo estadísticamente no es significativo. Los resultados de este estudio marcan un nivel de éxito del 100 por ciento hasta la actualidad, con un estado periimplantario altamente favorable y resultados estéticos muy buenos, con la ventaja de la reducción de los tiempos y pasos clínicos
