It is obvious from the figures above that the surgical treatment covers a wide spectrum. More over, the procedures involving bone augmentation, guided tissue regeneration and especially orthognatic surgery is more demanding in this group of patients than in general.
Maxillary osteotomy
1) |
With maxillary advancement and simultaneous transverse expansion of the maxilla there is a high risk of relapse. Surgical assisted rapid maxillary expansion (SARME) should therefore be considered. |
2) |
Relapse after inferior repositioning of maxilla can be reduced by the use of a Z-shaped osteotomy and grafting. |
3) |
Maxillary osteotomy should be performed after sinus floor augmentation, if a patient needs both procedures.
The mucosal lining of sinus is difficult to elevate without perforations,
if a maxillary osteotomy has been performed previously. |
4) |
Advancement of posterior segments (space - closing) is an alternative to sinus augmentation and implant placement. |
Mandibular osteotomy.
