Retrospective Study of Bone Grafting Procedures Before Implant Placement

Abstract

Alveolar reconstruction using autogenous bone followed by implant placement is a reliable treatment for patients with insufficient bone. Complications and morbidity were frequently observed. However, in only 6.6% of all procedures, the final rehabilitation with dental implants was not possible.

Enxerto ósseo mandibular, complicações associadas às áreas doadoras e receptoras, e sobrevivência de implantes dentários: um estudo retrospectivo

“…Para Naert et al 20 , a associação entre enxerto ósseo e implantes dentários deve ser considerada um fator de risco para perda de implantes dentários, não sendo verificada associação significativa, em nosso estudo, de um maior ou menor índice de sucesso quando o enxerto ósseo mandibular foi empregado. Quando as áreas mandibulares são utilizadas para reconstrução dos maxilares, observaram Rabelo et al 21 , apenas 6,6% do total de rebordos reconstruídos não permitiram a instalação dos implantes dentários planejados. Sbordone et al 4 realizaram uma análise comparativa da sobrevivência de implantes dentários em sítios maxilares e mandibulares reconstruídos com enxerto retirado da crista ilíaca ou da sínfise, e em áreas nas quais o implante dentário foi instalado no remanescente ósseo.…”

Cortical Bone Augmentation Versus Nerve Lateralization for Treatment of Atrophic Posterior Mandible: A Retrospective Study and Review of Literature

“…[40][41][42][43][44][45] The other three experiments measured graft-related complications. 18,46,47 This augmentative technique is considered as a modification of GBR and onlay bone grafting. In this technique, a thin cortical bone block from an intraoral donor site is used over a recipient site to create a secured healing space for particulate bone regeneration.…”

“…Six out of nine studies on onlay bone grafting reported survival rate of implants placed in the posterior mandible after ridge augmentation using intraoral bone grafts (Table ) . The other three experiments measured graft‐related complications …”

Long-Term Retrospective Evaluation of Dental Implants Placed in Resorbed Jaws Reconstructed With Appositional Fresh-Frozen Bone Allografts

“…(Implant Dent 2016;25:400-408) Key Words: block grafts, bone augmentation, homologous bone, survival rate the lack of possibility of disease transmission or host rejection. 3 Nevertheless, some drawbacks were reported, including donor site morbidity, limited availability, increased operating time, and possible complications related to the harvesting procedure such as neurosensory disturbances, prolonged healing, and opportunistic infections. 4 To overcome these limitations, bone-harvesting research activities were directed toward the application of biomaterials and bone substitutes.…”
