AbstractModern concepts in the world of beauty arise from popular models, beautiful faces of actors document a bi-protrusive asset with high tension for soft tissues. Facial symmetry has been proposed as a marker of development and stability that may be important in human mate choice. For various traits any deviation from perfect symmetry can be considered a reflection of imperfect development. Additionally, bi-protrusive profile is dependent on the hormonal level regardless of male or female sex. The goal of maxillofacial surgery is to provide best results both for aesthetic and functional aspects. Following these new concepts of aesthetic of the face, new surgical procedure by osteodistraction techniques will lead to a very natural result by harmonizing the face also preventing aesthetic decay in aging faces. Ten cases with a feedback on the aesthetic results using the fivepoint scale of Likert after orthognatic surgery performed following distraction new techniques in combination with ancillary surgical procedures.The aesthetic results in all patients were highly satisfactory. All the patients accepted the new aesthetic of the face avoiding elements of discrepancy and consequently medico-legal problems.

“…Disadvantages of these methods are their invasiveness, risk for infection, and necessity of a second surgical stage for appliance removal, after expansion. 14 Several different techniques are available to correct a maxillary transverse deficiency in adult patients, which are as follows: -Segmented Le Fort I osteotomy with down fracture, palatal expansion, and three-dimensional maxillary repositioning (Le Fort I-segmented expansion [LFI-E]) -Surgical-assisted RME by incomplete Le Fort I osteotomy (without down fracture) using dental-borne devices, the Hyrax (SARMEdental) -Surgical-assisted RME by incomplete Le Fort I osteotomy with bone-borne devices (SARME-bone), Pinto et al -Le Fort I osteotomy with down fracture, three-dimensional maxillary repositioning, and distraction osteogenesis with dental-borne devices (Le Fort I-Distraction Osteogenesis-Dental [LFI-DO]-dental) -Le Fort I osteotomy with down fracture, three-dimensional maxillary repositioning, and distraction osteogenesis with bone-borne devices (LFI-DO-bone) -Le Fort I osteotomy with down fracture, three-dimensional maxillary repositioning, and distraction osteogenesis with rigid boneborne devices (LFI-DO-bone-rigid) [15][16][17][18] The segmented Le Fort I osteotomy is a 1-step surgery that modifies maxillary dimensions and position in the 3 planes of the space; however, the limits of this technique are significant. Limits include the difficulty for a large amount of expansion because of the palatal fibromucosa tension, bone fragment tipping, root damage risk, bone necrosis of the premaxilla after periosteal elevation of the palatal bone, difficulties in the management of the bone fragments during fixation, 19,20 severe intraoperative and postoperative hemorrhage after damage of the descending palatine artery or other blood vessels, oroantral or oronasal communications, permanent instability of bone segments, and loss of gingival papillae after a large 1-step widening of the bone.…”

Maxillary constriction is a very common pathology with implications on dental occlusion, temporomandibular joint dysfunction, nasal breathing, and impairment on the smile and face esthetic.New techniques for expansion of the maxillary bones are particularly useful in relation to the new esthetic ideals of smile and face beauty.To achieve a bodily expansion of the maxillary bones, we developed a new rigid palatal distractor device with both tooth-borne and paramedian bone-borne anchorages to achieve a safe and simple anchorage site suitable also for orthodontic appliances.The reported cases show good results, with bodily maxillary expansion and cross-bite correction without any problems or complications. Substantial advantages of this new device and technique, in comparison with other commonly used palatal distractors, consisting of bodily maxillary movements, avoidance of relapse risks, and safe and simple screw insertion site for bone anchorage also suitable for orthodontic movements, are discussed.

“…The Le‐Fort I osteotomy is a typical kind of maxillofacial surgery and refers to separating the maxilla and the palate from the skull above the roots of the upper teeth through an incision inside the upper lip. Then, the fractured maxilla is fixed in its new position with titanium screws and plates . Maxilla cutting and drilling are the main procedures for Le‐Fort I osteotomy and the algorithms of the corresponding simulations are described as follows.…”
