Problems occurring after alveolar ridge split or bone blocks transfer procedures.
Unfortunately, the operations that increase the bone volume are connected with a number of risks and different complications. They include paresthesia, which may occur after the bone blocks takeoff, their volume loss in the process of their reconstruction, the probability of being contaminated, etc.
However, the greatest problem in the early post-operative period is a partial cutting of the bone fragments or bone blocks, which can be separated in different sides. We always want to create the bone volume that would be sufficient for the future implantation. However the elasticity of the mucoperiosteal flaps and level of their immobilization not always allow to align them adequately and to suture them above the newly created volume with without excessive tension.
So try to separate flops with the maximal depth and during the surgery get them back and evaluate their possible tension.
Try to evaluate the soft tissues flexibility, their volume and the possibility of their future immobilization at the first meeting with the patient. Palpate the alveolar ridges and the mucosa with special attention!
4.8-1A
On the 12th day after the surgery, the bone block cut through, and the alveolar ridge was uncovered. A significant part of the block had to be removed, the flops were deepithelialised, and the wound was sutured again.
4.8-1B
View of the performed surgery 10 days after extraction of the cutting fragment (23 days after the bone block transplantation).
4.8-1C
After 2 more months, the area of the performed surgery looked like this (80 days after the bone block was transplanted).
