A prospective, controlled clinical trial evaluating the clinical and radiological outcome after 3 years of immediately placed implants in sockets exhibiting periapical pathology

Abstract

Abstract:Objectives: The aim of the present study was to compare the clinical and radiological outcome of immediately placed implants in sockets with or without periapical pathology 3 years after implant placement. Materials and methods:29 patients with immediate implant placement were clinically and radiologically followed 3 years after implant placement (test-group: 16 patients without periapical pathology, control-group: 13 patients with periapical pathologies). Clinical (FMBS, FMPS, CAL, width of keratinized mucosa buccaly of the implant) and radiological parameters (IS-BIC) were assessed. Both 95% confidence intervals, as well as results of statistical tests (one-sample, two-sample, paired t-test) were provided. Results:The implant survival rate was 100% for all 29 implants after 3 years. The clinical and radiological parameters showed no statistically significant difference between the testand the control-group at 3 years (two-sample t-test). The vertical distance from the implant shoulder to the first bone-to-implant contact (IS-BIC) was between 1.54±0.88 mm (mesial, test) and 1.69±0.92 mm (distal, test). Between the 1-and 3-year visit the IS-BIC increased in both groups significantly on one side of the implant: 0.30±0.37 mm (mesial, test) and 0.33±0.43 mm (distal, control) (one-sample t-test). None of the 13 examined radiographs of implants immediately placed in sockets with periapical pathologies revealed retrograde periimplantitis after 3 years. Conclusion:It is concluded within the limitations of this study, that after careful debridement of the extraction socket, immediate placement of implants into sites with periapical pathologies can be a successful treatment modality for at least 3 years with no disadvantages in clinical and radiological parameters to immediately placed implants into healthy sockets.

Effect of PRF and Allograft Use on Immediate Implants at Extraction Sockets with Periapical Infection —Clinical and Cone Beam CT Findings—

“…Moreover, many studies have reported an increase in loss of endosseous implants at sites associated with periodontal disease 12,24,35) , whereas few have reported satisfactory results 13,20) . Similar success rates have been reported, however, with immediate implant placement whether the site was infected or not, provided infection was controlled thorough debridement of alveolar tissue by curettage and administration of broad-spectrum antibiotics 17,20,31,32,50,55) .…”

“…Hence, the presence of periapical infection should not be considered as a potential contraindication for immediate implant placement. Furthermore, human clinical studies have reported that implant survival rate ranged from 92 to 100% after 12 to 60 months of follow-up 13,17,20,31,32,50,55) . One study reported that the implant survival rate was 100%, and that hard and soft tissue integration was similar and favorable between the healthy and infected groups 18) .…”

“…Many studies have investigated immediate implant placement in infected extraction sockets due to periapical lesions 5,12,13,17,20,24,31,32,35,55) . Few have investigated the potential adjunctive effect of concomitant use of PRF and DFDBA bone grafts in such cases, however, which was, therefore, the purpose of the present study.…”

Tratamiento de fractura coronorradicular con implante inmediato postextracción Thommen SPI® Element y revisión de la literatura

“…El empleo de Bio-Oss® , utilizado en este caso clínico, como biomaterial de relleno en defectos óseos, periodontales e implantológicos, ha demostrado una gran eficacia clínica en el tratamiento con implantes, siendo importante a la hora de evitar en lo posible, el proceso de reabsorción ósea del alvéolo postextracción que va intrínsecamente unido a la cicatrización postexodoncia (31)(32)(33). Este material, debe utilizarse, en un favorable "ambiente osteogénico", situándolo sobre un lecho receptor que favorezca la revascularización rápida del material injertado y con la mayor estabilidad posible, en función del material utilizado, morfología y tamaño del defecto, así como la técnica que finalmente se haya decidido emplear (34,35).…”

“…(1) Estudos clínicos têm demonstrado que a taxa de sucesso dos implantes imediatos é similar a dos implantes instalados após o reparo ósseo. (2)(3)(4)(5) Evidências científicas demonstram que a implantação imediata preserva a arquitetura alveolar e favorece a manutenção da altura das cristas ósseas, (6,7) assim, a manutenção do contorno e da espessura gengival é favorecida, fatores essenciais para uma ção do longo eixo do cabo em relação a raiz dentá-ria (Figura 3, Apêndice A).…”
