Premaxilla Ridge Augmentation
Pre-op photos. The profile photo shows a concavity underneath the nose and significant nasiolabial folds. The frontal face photo, the upper left lip rolls under the lower lip. The collapse of the premaxilla creates an unattractive smile.
Severely atrophic premaxilla. The lack of width of the premaxilla is not just a bone volume problem, but due to the thin ridge, there are areas where there is nearly no trabecular bone between the cortical bone plates. Trabecular bone is the source of the regenerative cells that are needed to convert the bone graft into bone.
In planning a regenerative surgery, consideration must be given where the regenerative cells are located and how they will reach the bone graft, as well as how long it will take for them to migrate into the bone graft before other cells arrive or resorption occurs.
From the CT scan, a plastic model is constructed. The model is shipped to SteinerBio and the bone graft is constructed under sterile conditions. In this case, the bone graft comprises of Ridge Graft™ mixed with OsseoConduct™ beta tricalcium phosphate standard granules, covered with OsseoConduct™ Cortical Plates. The bone grafts are packaged sterile, refrigerated, and shipped to the surgeon. The surgeon opens the tissue, perforates the buccal bone, and inserts the bone grafts.
With the case complete, a natural pleasant smile is achieved. Only a dentist can restore or improve facial esthetics. If bone and teeth are lost, muscle atrophy usually follows, producing and aged, asymmetrical, unattractive facial appearance that plastic surgery cannot restore.
