[Orthognathic surgery and contour plasty. Synergism or opposition].

The article presents two cases of sisters with malocclusion: distal deep bite with typical skeletal and soft tissue deformation. In the first case classic three-steps orthognatic treatment plan was realized: orthodontic preparation with subsequent orthognatic bi-maxillar surgery with genioplasty. In second one we made contour-plasty with implants. Two different plans follow to two different results. Discussion around all differences of two approaches is the main interest of this overview.
