No results posted yet for this study

Summary

immediate implant placement using the VST was compared to early implant placement protocol using Buser's technique regarding implant survival, changes in labial plate thickness and soft tissue height after 1 year of implant placement

Conditions

  • Dental Implant Failed

Interventions

OTHER

VST and immediate implants

One-cm long vestibular access incision was made using a 15c blade 3-4 mm apical to the mucogingival junction at the related socket . A subperiosteal tunnel was created connecting the socket orifice and the vestibular access incision using periotomes and micro periosteal elevators (. Implant fixture were then inserted after drilling to its pre-planned location 3-4 mm apical to socket base with adequate primary stability achieved using a torque wrench reaching 30 Ncm torque . A flexible cortical membrane shield that is made of cortical bone of heterologous origin of 0.6 mm thickness was hydrated and then trimmed and introduced from the vestibular access incision reaching 1 mm below the socket orifice through the tunnel . The socket gap between the implant and the shield was then packed thoroughly with particulate bone graft

Buser technique and early implants placement

In Buser's group early implant placement, the failing tooth was extracted atraumatically using a periotome. A collagen plug was placed to stabilize the wound clot. A healing period of 4-8 weeks (depending on the size of the extracted tooth) was followed. Then an open flap implant surgery using a triangular flap design was cut. After preparing the implant bed, the site was irrigated using normal saline. A healing abutment was then attached. Contour augmentation was done using autogenous bone chips mixed with saline and bone. A non-cross liked membrane was then placed, after being soaked with BCM. Finally, the healing abutment was removed and the flap was released to allow for its suturing.
