CLINICAL CASE

1 – The basis for planning implant therapy is clinical and radiological diagnosis with a CBCT scan.
2 – A precise 3-D planning model will be created based on CBCT data. Adaptations of the exact shape are possible, depending on the surgeon’s preference and feedback.
3 – The usual oral surgery and implantology hygiene provisions apply for the use of Yxoss CBR® intraoperatively. The same applies to patient medication.
4 – The opening incision should be designed in accordance with the extent, location and with respect to the anatomical structures of the region to be augmented.
5 – Subsequent steps are the preparation of a mucoperiosteal flap, debridement of scar tissue and the exposure of the defect. Sufficient blood supply of the flap is favored by a flap with a wide base.
6 – Autologous bone can be harvested from the usual intraoral donor sites and can be mixed with bone substitutes (e.g. Geistlich Bio-Oss®).
7 – The Yxoss CBR® is initially filled with autologous bone and bone substitute material (e.g. Geistlich Bio-Oss®).

9 – A resorbable membrane (e.g. Geistlich Bio-Gide®) should be placed over the Yxoss CBR® to prevent ingrowth of soft-tissue and to support soft-tissue regeneration over the titanium frame.
10 – The wound should be closed completely whenever possible. The mucoperiosteal flap is positioned tightly but tension-free over Yxoss CBR® with single interrupted and deep mattress sutures. Pressure on the augmented crest has to be avoided. Dentures are not to be applied.
11 – Before reopening, clinical and radiological diagnosis are to be taken into consideration.
12 – Reopening of the augmented site approx. 4 to 6 months post surgery and depend on the defect geometry, at latest 9 months after initial surgery.
13 – After removing the fixation screws, Yxoss CBR® can be easily removed using preset breaking points
14 – Newly formed vital bone is regenerated up to the contour defined by the shape of the Yxoss CBR®.
15 – Insertion of implants into the augmented alveolar ridge according to the prosthetic position.
16 – Prosthetic restoration is carried out in accordance with the usual precautions.

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.

Incision design showing the sulcular incisions with horizontal incisions across the interdental regions ending with a remote oblique vertical releasing incision distal to the first bicuspid tooth.
Geistlich Fibro-Gide® is trimmed in a dry state to 10 x 15 x 6mm. The corners were trimmed for better adaptation and the matrix was then hydrated in sterile saline solution.
The interdental papillae were de-epithelialized and Geistlich Fibro-Gide®was placed over the exposed roots extending onto the bone. Geistlich Fibro-Gide® was not secured with sutures.
Internal periosteal releasing incision was made to allow tension-free coronal advancement of the buccal flap to completely cover Geistlich Fibro-Gide®.The flap was secured with 5-0 Monocryl® sutures.
1-week post-operative visit: the healing looks good and sutures are intact. There was a small soft-tissue dehiscence at the buccal margin of the canine tooth.
Healing progressed well at 2 months post-operatively and the dehiscence defect seen at 1 week appears to be healing. Soft-tissue thickness is also evident at this stage.
At 6 months, 100% root coverage has been achieved. Note the increase in keratinized gingiva at the canine tooth where there was previously delayed healing. The patient is happy with the esthetic and functional outcome.

CLINICAL CASE

1 – Pre-operative view of the atrophied ridge.
