RESUMO
Este trabalho tem por objetivo relatar um caso em que foi realizada a técnica de Summers para elevação do seio maxilar, associada à realização de osseodensificação. Paciente do gênero masculino, 53 anos, apresentando ausência do dente 17, com altura reduzida na área edêntula. Foi realizada a elevação do seio maxilar pela técnica de Summers associada à osseodensificação da região para uma melhora da qualidade óssea. Foi instalado um implante cone morse SIN de 3.8 x 8.5 com torque de 45 newtons. No acompanhamento pós-operatório não houve qualquer sinal ou sintoma de complicação e o paciente foi reabilitada com uma prótese parafusada sobre implante.
This study aims to report a case in which the Summers technique was performed for maxillary sinus elevation, associated with osseodensification. Male patient, 53 years old, with missing tooth 17, with reduced height in the edentulous area. Maxillary sinus elevation was performed using the Summers technique associated with osseodensification of the region for an improvement in bone quality. A 3.8 x 8.5 SIN morse taper implant with a torque of 45 newtons was installed. In the postoperative follow-up, there were no signs or symptoms of complications and the patient was rehabilitated with a screw-retained implant prosthesis.
Este trabajo tiene como objetivo informar de un caso en el que se realizó la técnica de Summers para la elevación del seno maxilar, asociada a la osteodensificación. Paciente varón, de 53 años, que presenta ausencia del diente 17, con altura reducida en la zona edéntula. Se elevó el seno maxilar mediante la técnica de Summers asociada a la osteodensificación de la región para mejorar la calidad ósea. Se instaló un implante morse cónico de 3,8 x 8,5 SIN con un par de 45 newtons. En el seguimiento postoperatorio no hubo signos ni síntomas de complicación y el paciente fue rehabilitado con una prótesis atornillada sobre un implante.

Con el objetivo de tratar mediante implantes dentales zonas de tejido óseo incipiente y minimizar el uso de técnicas más invasivas, surge la oseodensificación (OD), una técnica realizada mediante la utilización de fresas Densah®, diseñadas para aumentar la densidad ósea, desplazando y condensando el tejido óseo circundante al fresado. El objetivo del estudio fue determinar los cambios dimensionales en ancho y altura del reborde óseo alveolar (ROA) en zonas posteriores del maxilar utilizando la técnica de OD, 3 meses posterior a realizada la cirugía. Se realizaron evaluaciones imagenológicas mediante Cone-Beam-CT (preoperatorio y mínimo 3 meses postoperatorio) a 9 pacientes, en los que se instalaron 10 implantes, divididos según instalación mediata e inmediata. En ambos grupos, se midió el ancho del ROA tanto a nivel marginal, utilizando como referencia el plano de la cresta ósea vestibular (COV), como 4 mm apical al plano COV. También se midió la altura del ROA con relación al plano COV y al piso del seno maxilar (PSM). Las comparaciones se realizaron mediante el análisis estadístico prueba t student-muestras pareadas. Los datos imagenológicos mostraron un valor de p<0,05 para la expansión ósea, tanto en ancho (solo implantes mediatos, media 2,11 ± 1,66 mm) como en altura con relación a PSM (implantes mediatos e inmediatos, medias de 2,28 ± 2,21 y 1,88 ± 1,82 respectivamente). La técnica de OD resultó ser efectiva en generar un aumento, tanto en ancho de implantes mediatos a nivel del plano COV como en altura del ROA en implantes mediatos e inmediatos.
In order to treat areas of incipient bone tissue with dental implants and minimize the use of more invasive techniques, osseodensification (OD) is a technique performed using Densah® drills, designed to increase bone density by displacing and condensing the bone tissue surrounding the drill. To determine the dimensional changes in width and height of the alveolar bone ridge (ABR) in posterior regions of the maxilla using the OD technique, 3 months after surgery. Imaging evaluations were performed by Cone- Beam-CT (preoperative and at least 3 months postoperative) in 9 patients, in whom 10 implants were installed, divided according to mediate and immediate installation. In both groups, the width of the ABR was measured both at the marginal level, using the vestibular osseous ridge plane (VOR) as a reference, and 4 mm apical to the VOR plane. The height of the ROA was also measuredin relation to the VOR plane and the maxillary sinus floor (MSF). Comparisons were performed by student t-test paired-samples statistical analysis. Imaging data showed a value of p<0.05 for bone expansion, both in width (mediated implants only, mean 2.11±1.66 mm) and height in relation to PSM (mediated and immediate implants, means of 2.28±2.21 and 1.88±1.82 respectively). The OD technique proved to be effective in generating an increase in width of dental implants mediated at the level of the VOR plane and in height of the ABR (mediated and immediate implants).
RESUMO
Background: Dental Implant originally utilized for aesthetic and functional rehabilitation, this treatment option have transformed oral rehabilitation techniques and are now regarded as the gold standard of treatment for replacing single, partial, and full-arch teeth. With improvements in osteotomy technique, implant macro- and micro-geometry, surface treatment, types of implant prosthetic connections, and other aspects, the overall treatment duration has also been greatly shortened.Material & Methods:This study was carried out in two implant centers and is retrospective and descriptive. It was done in the Implant Surgery Centers of Banasree Dental and German Dental, Dhaka, Bangladesh. The research was carried out from January 2010 to June 2022. 63 people made up the entire sample for this study.Results:Most of the patients 21(33.3%) were aged between 51-60 years where most of the patients 36(57%) were female and 27(43%) were male. Maxilla was done in 45(71.4%) patients, mandible was done in 48(76.2%). 69(74.2%) implants were done on the anterior site and 24(25.8%) was done on posterior site. All the patients had a good primary stability of implant with an insertion torque of 30 N/cm or more. There were 100% survival rate after the implants and in good functional condition. All patients were happy with their implant.Conclusion:This approach of osteotomy preparation’s greater primary stability appears to have a minimal detrimental effect on implant success.
