Mandibular midline distraction using a tooth-borne device and a minimally invasive surgical procedure

Minimally Invasive Genioplasty Procedure

“…In the presented approach, the vertical incision through the lower lip frenulum leaves a short and inconspicuous scar in the midline. 9 , 10 The mentalis muscles are kept intact, eliminating possible myodysfunction. The advantages of this technique above alloplastic implants are those of a standard genioplasty: no foreign body, effective in correcting vertical or transverse deformities of the mentum, not limited in size and shape, no bone resorption resulting from the implant, and so on.…”

“…Optional, a chin hook, as used for the transmandibular midline distraction osteotomy, can facilitate the osteotomy, in this case there is no need to make the horizontal groove. 10 The design of the osteotomy is influenced by the esthetic requirements. There are no chin wing osteotomies performed with this technique.…”

Pharyngeal airway changes following symohyseal distraction osteogenesis

“…On the other hand, tooth-borne and hybrid distractors are less invasive and cheaper, but do not yield pure skeletal results. They mostly yield larger dentoalveolar expansion with dental tipping [11,16,17] . Airway parameters might be easily altered as a consequence of separation of the two mandibular halves.…”

Mandibular Midline Distraction Osteogenesis with a Bone-borne, Tooth-borne or Hybrid Distraction Appliance: a Systematic Revieww

“…However, bone-borne distraction appliance is associated with increased cost, extended duration of surgery, trans-mucosal hardware emergence and the need of a second operation to remove the distraction appliance [ 1 , 10 ]. Tooth-borne distraction appliance apply their vector on the dentoalveolar level and generally facilitate a disproportionate transverse expansion pattern with a larger alveolar bone widening than the basal mandibular bone as well as dental-tipping [ 2 , 12 , 13 ]. However, tooth-borne distraction appliance is cheaper, cemented preoperatively and provides better aesthetic and patient comfort especially when a lingual device is used [ 1 , 12 , 13 ].…”

Hybrid distraction appliance combines advantages of bone-borne and tooth-borne appliance, since the appliance is attached to both the bone and teeth [ 13 , 14 ].…”
