CLINICAL CASE

Initial situation, patient presented with radiographic and clinically traditional signs of peri-implantitis, including bleeding on probing, suppuration, radiographic progressive bone loss and clinical pathologic probing depths.
Mechanical debridement was achieved using titanium scalers, an ultrasonic device with an implant protective cap and titanium brushes to remove all of the visible contaminants of the implant surface. Citric acid was then placed on shreds of a non-woven gauze and applied to the surface for approx. 1min. Copious irrigation was done using saline solution and the surface was ablated using the Er:YAG laser at 20pps/50mj.
After the surface was prepped and no signs of residual granulation tissue was noted, the defect was grafted with Geistlich Bio-Oss®. Attention was given towards not augmenting beyond the bony envelope.
A protective Geistlich Bio-Gide® membrane was placed over Geistlich Bio-Oss®.
Geistlich Fibro-Gide® was placed over Geistlich Bio-Gide® to enhance soft-tissue volume and quality. Geistlich Fibro-Gide® was trimmed and adapted to the defect site ensuring a tension free closure.
Geistlich Fibro-Gide® was place on the top of the bone graft to enhance soft-tissue thickness. Geistlich Fibro-Gide® is porous. We can observe the rapid penetration of blood through the matrix.
Closure with a tension-free flap was achieved by releasing incisions and secured using 4-0 chromic gut sutures.
1.5 year post-operative photo and radiograph show the healing of the soft-tissues with no signs of peri-implantitis and adequate tissue thickening. Radiographic bone levels have maintained stable over the course of the year.
