Smile 3 Distractor
Skeletal expansion or Surgically assisted rapid palatal expansion is undoubtedly the best treatment option for maxillary hypoplasia and/or severe max. crowding. The advantages are obvious and multiple. There is no segmental tilting, there is no evidence of any orthodontic/orthopedic relapse and dental/ periodontal damage is excluded.
– Modules can be changed or removed without removing the plates and the screws
– Very useful distractor for pathological small upper jaws and clefts (module 8, 10, 12 mm)

Sequence of the surgery
- Corticotomies: lateral – midline + posterior disjunction
- Placement of the UNI-Smile Distractor with self-drilling screws between teeth n° (14)- 15-16 and (24)-25-26
Sequence of the distraction
- At the end of the surgery the blocking screw is tightly engaged, using wrist force. Place a tampon in case the blocking screw should drop.
- One week after the surgery the activation of the Smile Distractor is started. Remove the blocking screw and expand untill bone resistance is felt, then turn once or twice more. During activation (1 to 2 weeks) the patient should turn two times a day a quarter of a turn. At each quarter of a turn a new colour appears.
- After completion of the distraction put the blocking screw back real firm, using wrist force. The distractor needs to be in place 3 to 6 months.

Dr Defrancq (Anwerp, Belgium, http://www.facialsculptureclinic.com) made the following treatment plan: the goal was a 10 mm advancement of lower jaw (BSSO adv.) and chin point (genioplasty adv.). Since her lower teeth were damaged periodontally and manifest decay problems were present, Dr Defrancq decided to extract the lower teeth and replace them by implants in the proper angular position. This made it possible to advance the lower jaw 1 cm, necessary to relieve her from the sleep apnoea. The upper jaw was advanced (Le Fort I adv.) to meet the lower implant-teeth situation. The chin was advanced as much as aesthetically affordable. This also stretches the tongue muscles forward with a clear impact on the posterior airway. At the same time a smile distractor was placed to enlarge her too narrow maxilla. Enlarging the too narrow upper jaw has indeed a great impact on the palatal muscles, significantly broadening the upper airway.
