Augmentation post implant failure using Bond Apatite bone cement
In the following case, a failed #29 (45) implant needed to be removed and the defect was to be augmented with Bone cement
(Bond Apatite ®Augma biomaterials ltd.)
After sulcular incision and detachment of the soft tissue from the implant,a buccal flap was minimally raised. The implant was then removed.
After complete debridement and granulation tissue removal,
BA cement was ejected directly into the defect.
The graft was compacted by finger pressure over a dry sterile gauze pressing and molding the graft for 3 seconds. This is adequate time to achieve graft set and stability. The flap was then sutured.
The flap was not dissected for release since according to
BA protocols the flap should be placed directly on the graft with
tension and not tension free.
Healing was uneventful and 12 weeks post-op implant placement took place. The presence of higher bone peek levels mesially and distally enabled the placement of the implant above the buccal aspect of the alveolar crest and to augment over the exposed threads, of this newly placed implant, with additional BA cement at this stage.
