Restoring the congenitally missing lateralby dr. John Tsourounakis
Clinical examination revealed a class I Siebert ridge deficiency. You can appreciate the severe horizontal ridge deficiency at the CBCT scan.
Augmentation of the deficient site was done with a combination of autogenous bone, obtained from the base of the maxilla with a trephine, and bovine xenograft. The composite graft was covered with an absorbable collagen membrane.
A CBCT scan, taken 6 months following the augmentation procedure, revealed a significant increase of the edentulous site.
An Astra Osseospeed EV implant, 3.0x13mm was placed in a restoratively driven position. An autogenous soft tissue graft was placed at the buccal of the implant to enhance the esthetics of the future restoration.
