ABSTRACT

Objetivo: En este estudio se realiza un seguimiento de implantes inmediatos con carga inmediata en alveolos afectados por periodontitis activa, con el fin de determinar la supervivencia de los mismos, la pérdida ósea y otras variables que puedan suponer el fracaso del tratamiento tanto quirúrgico como protésico. Material y métodos: Fueron seleccionados pacientes a los que se les colocaron implantes inmediatos post-extracción con carga inmediata en zonas afectadas por periodontitis durante 9 años (desde diciembre de 2006 hasta enero 2015). Se recolectó de forma retrospectiva información relativa a los datos demográficos, datos relativos al implante y datos relativos a la evolución del implante a lo largo del tiempo de seguimiento (estabilidad de los tejidos blandos, duros y prótesis). Se calculó la pérdida ósea marginal por implante y la supervivencia de los implantes y prótesis. Fue calculada también por implante la distancia entre el implante estudiado y su implante o diente adyacente y las repercusiones que tuvo esta distancia en el comportamiento del tejido blando peri-implantario y la formación de papila. Resultados: Fueron reclutados 25 pacientes en los que se insertaron 39 implantes post-extracción inmediata con carga inmediata en zonas infectadas por periodontitis. El tiempo medio de seguimiento fue de 6 años (rango 1 a 7 años). únicamente 3 de los implantes incluidos en el estudio no cumplieron con los criterios establecidos para el éxito implantológico y la supervivencia de los implantes fue del 100%. La media de pérdida ósea marginal fue de 1,50 mm (rango 0,61-5,01 mm). No se registró ningún fracaso de prótesis en los ca-sos estudiados aunque si un 6% de incidencias protésicas (aflojamiento de tornillos y fracturas de porcelana). Se encontró una correlación estadísticamente significativa entre la distancia al implante-diente adyacente y la estabilidad del tejido blando tras la cirugía (p=0,038). La media de la distancia entre el implante estudiado y el implante o diente adyacente cuando el tejido blando se mantuvo estable tras el tratamiento fue de 3,10 mm ±1,67 y cuando no se mantuvo estable fue de 2,09 mm ±1,95. La distancia media al diente-implante adyacente cuando se formó papila fue de 2,96 mm ±1,95 mm. Conclusiones: La carga inmediata de implantes post-extracción inmediata en implantes afectados por periodontitis (infección activa en el momento de la inserción del implante) no es un factor de riesgo para la supervivencia de los implantes según los datos obtenidos por este estudio (AU)


Objective: In this study is a follow-up of immediate implants with immediate loading in a post-extraction sockets affected by acute infection was made, in order to determine the survival of the implants, bone loss and survival of the implants and prosthesis. Material and Methods: patients who have implants immediate post-extraction with immediate loading in areas affected by periodontitis during 9 years (from December 2006 until January 2015) were selected. Retrospectively collected information on demographic data, data relating to the implant and data relating to the evolution of the implant over time of follow-up (soft tissue stability, hard and prosthesis). We calculated the marginal bone loss by implant and the survival of the implants and prostheses. The inter-implant distance was calculated by the distance between the implant and implant or adjacent tooth and the repercussions of this distance on the behavior of the peri-implant soft tissue and the papilla formation. Results: Finally 25 patients and 39 implants were included in the study. The mean follow-up time was 6 years (range 1 to 7 years). Only 3 of the implants included in the study did not meet the criteria for implantological success and the survival of the implants and prosthesis was 100%. The mean marginal bone loss was 1.50 mm (range 0.61-5.01 mm). In a 6% of the prosthesis mechanical complications were observed (loosening of screws and porcelain fractures). A statistically significant correlation was found between the distance to the adjacent tooth-implant and the stability of the soft tissue after surgery (p=0.038). The average distance between the implant and the implant or adjacent (AU)

ABSTRACT

Objetivos. Evaluar el valor pronóstico de la movilidad primaria (momento de inserción del implante) y secundaria (fase protésica), así como el de la densidad ósea en el resultado de éxito o fracaso del implante durante un seguimiento continuado al año, a los 5 años y a los 10 años. Material y métodos. Se realizó un estudio longitudinal prospectivo con un seguimiento a 10 años en el que se incluyeron 151 implantes colocados en 71 pacientes, no fumadores, durante los años 2005 y 2006. A cada uno de los implantes se les midió las estabilidades primaria y secundaria a través de un valor Periotest® (VPT) y se anotó la densidad ósea presente en el momento de la implantación. De los 151 implantes colocados inicialmente, completaron el estudio 109. Resultados. No se observaron diferencias estadísticamente significativas respecto a la movilidad del implante en el momento de inserción o en la fase protésica y el éxito o fracaso del mismo al año, a los 5 años, o transcurridos 10 años desde su inserción. Sí encontramos diferencias estadísticamente significativas con relación al tipo de densidad ósea donde se colocó el implante a los 5 y 10 años (p<0,05). Conclusiones. La movilidad primaria o secundaria del implante carece de valor pronóstico significativo sobre el éxito del mismo transcurridos 10 años desde su inserción. Por el contrario, la densidad de hueso inicial tiene una clara influencia en el éxito del implante a los 10 años, siendo más proclives al fracaso los huesos de alta densidad ósea (AU)


Purposes. To prospectively analyze the prognosis value of the primary mobility (at the moment of implant insertion) and secondary (prosthetic phase), as well as bone density, in the implant success or failure after one year, five years and ten years. Materials and methods. Between 2005 and 2006, 151 implants were placed in 71 non-smoking patients. Primary (at the moment of surgery) and secondary (once osseointegrated) stabilities were measured in each implant through a Periotest® value (PTV) and the bone density was scored at the moment of implantation. One hundred nine of 151 implants placed initially completed the study. Results. There were no statistically significant differences regarding implant mobility at the moment of its insertion or once osseointegrated and the implant success or failure after 10 years. However, statistically significant differences were found respect to the bone density where the implant was placed after 5 and 10 years (P<.05). Conclusions. Primary or secondary mobility of the implant has no significant prognosis value on the implant success after 10 years. On the other hand, bone density has a clear influence on long time implant success. High density bones are more predictable to fail than low density bones after a long time (AU)

ABSTRACT

O objetivo dessa revisão foi buscar na literatura o que há de mais atual no que envolve a implantação imediata (I.I.), abordando aspectos de seleção do paciente, de planejamento, cirúrgicos e protéticos e determinando o tipo de tratamento mais previsível. Para isso, foi realizada uma pesquisa bibliográfica no PUBMED com as palavras-chave esthetic, immediate dental implant e review, totalizando 40 trabalhos. Foram selecionados 23 trabalhos pertinentes ao tema. Posteriormente foram realizadas novas buscas com as palavras-chave atraumatic extraction, connective tissue, bone graft, guided surgery, flapless immediate implant vs flap, socket shield, immediate provisionalization, platform switching, associadas com a palavra-chave immediate implant. Além disso, foram realizadas pesquisa e seleção manual na lista de referências dos trabalhos em questão e também acrescentados uma revisão de literatura na língua portuguesa e trabalhos de 2017 relevantes ao tema, totalizando 72 trabalhos para confecção desta monografia. Com base nesta revisão de literatura, as conclusões foram de que não há consenso sobre o tratamento cirúrgico/protético mais previsível em I.I.; o planejamento digital parece favorecer os resultados da I.I.; o momento de instalação tipo 2 do implante é o tratamento mais previsível; a determinação do remanescente ósseo é fundamental para o planejamento em I.I.; deve-se preferencialmente realizar I.I. em pacientes com fenótipo periodontal espesso; a abordagem cirúrgica sem retalho, o uso de enxerto de tecido conjuntivo subepitelial e o implante imediato com plataforma trocada parecem ter resultados estéticos mais favoráveis; a técnica de preservação radicular associada ao I.I. parece favorecer o resultado estético; o uso de enxerto ósseo no alvéolo durante a colocação de implante imediato permite menor alteração dos volumes teciduais; a provisionalização imediata parece favorecer o resultado estético a curto prazo quando é associada a enxerto ósseo e garante uma manutenção dos volumes de tecido mole


The objective of this review is to search the literature for the most current in what involves immediate implantation (I.I.), addressing aspects of patient selection, planning, surgical and prosthetic and determinants of the type of more predictable treatment...

ABSTRACT

BACKGROUND: Discrimination between ongoing and solved research questions may help to distinguish established dogmas from evidence-based implant dentistry. PURPOSE: The purpose of this study was to investigate topics of interest in the field of oral implant science and evolving thematic trends in clinical studies during the last decade. MATERIALS AND METHODS: Electronic and manual searches of English literature were performed to identify clinical studies on oral implants. Out of 15,695 publications screened, 2,875 clinical investigations were included. RESULTS: Among the most prevalent topics were immediate loading (14.3%), bone substitutes (11.6%), lateral sinus grafting (10.7%), implant overdentures (10.5%), single-tooth implant crowns (8.8%), cross-arch implant bridges (8.0%), immediate implant placement (7.5%), implant surfaces (7.0%), simultaneous implant placement and augmentation (6.4%) as well as guided bone regeneration (5.3%). Significant increase of scientific interest was seen in immediate loading (+6.3%, p < .001), platform switching (+2.9%, p < 0.001), lateral sinus grafting (+2.3%, p = .024), flapless implant surgery (+2.2%, p < 0.001), and guided implant surgery (+1.9%, p = .011), while research on implant overdentures (-6.6%, p = .033) and tooth-to-implant connection (-2.5%, p = .010) was on the decline. CONCLUSIONS: Literature coverage, since the beginning of the 21st century, has seen greater focus on surgical topics compared to prosthodontic issues (p = .005) while only few topics experienced decrease of interest indicating scientific consensus.

ABSTRACT

Introducción. Los eventos de estrés, como una cirugía bucal, pueden elevar los niveles de catecolaminas circulantes produciendo un alza en la presión arterial a niveles dañinos para el organismo. Nuestra investigación tiene como propósito determinar si existe una variación estadísticamente significativa de la presión arterial durante la cirugía de implantes. Materiales y método, Se registró la presión arterial sistólica (PS) y diastólica (PD) a 30 individuos sometidos a una cirugía de implantes mediante un monitor Dinamap Pro 400. Se calculó el valor de la presión arterial media (PM) y, finalmente, se determinó la diferencia entre la PM inicial de cada individuo y el valor más alto de la PM alcanzado durante la cirugía. Resultados. El promedio de las PM iniciales fue de 91,452 mmHg y el promedio de las PM máximas alcanzadas durante la cirugía fue de 104,476 mmHg, existiendo diferencia estadísticamente significativa (p = 0,0005). Conclusión. Se observa un alza significativa en los valores de PM registrados en los individuos durante la cirugía de implantes, por lo que es importante considerar esta alza en todos los pacientes que serán sometidos a dicho procedimiento y más aún en aquellos que ya posean valores elevados de su presión arterial de manera a evitar posibles complicaciones (AU)


Introduction. The stress situations like an oral surgery can increase the blood catecholamines, producing an increased arterial blood pressure to levels that could damage health. This study attempt to determine whether there is a statistically significant variation in the arterial blood pressure during dental implant surgery. Materials and method. We registered the blood pressure - systolic (SP) and diastolic (DP)- to 30 subjects undergoing implant surgery with the Dina map Pro 400 monitor. We calculated the mean arterial blood pressure (MP) and finally we determined the difference between initial mean blood pressure and the highest blood pressure value reached at surgery. Results. The mean of the initial mean blood pressure was 91.452 mmHg and the mean of highest mean blood pressure reached during surgery was 104.476 mmHg, obtaining statistically significant differences (P=.0005). Conclusion. As there was a significant increase in the MP values recorded in subjects during dental implant surgery, this should be taken into account in all patients undergoing to this procedure, and particularly in those with hypertension, to avoid possible complications (AU)
