Changes in the mandibular and dento-alveolar structures by the use of tooth borne mandibular symphyseal distraction devices

Skeletal and dental effects of tooth-borne versus hybrid devices for mandibular symphyseal distraction osteogenesis

“…Both toothborne and hybrid distraction devices are recognized for their effective treatment of mandibular crowding. 8,14,15,18 Analysis of study models and radiographs supported the use of both tooth-borne and hybrid distractors to effectively resolve mandibular crowding. The results were consistent with previous literature stating that the greatest expansion takes place nearest to the site of distraction.…”

“…Other studies of tooth-borne distraction have also demonstrated dental changes through increased proclination of mandibular anterior teeth. 14,18 DelSanto et al 14 showed a greater increase in lower incisor angulation for the tooth-borne distractor than for the hybrid distractor. The more disproportionate regenerate and the greater proclination of mandibular incisors suggest that expansion with a tooth-borne distractor is gained through greater dental effects than MSDO with a hybrid distractor.…”

Mandibular midline distraction: A systematic review

“…Of note are the small sample sizes of the studies implying low power, with only two studies having a sample size of over 30 patients von Bremen et al, 2008). The medical ethical committee was consulted in six of the studies (Iseri and Malkoc, 2005;Duran et al, 2006;Malkoc et al, 2006;Bayram et al, 2007;Landes et al, 2008;Seeberger et al, 2010). Only Weil et al included an error analysis (Weil et al, 1997).…”

Innovation in anterior mandibular alveolar distraction osteogenesis: Introduction of a new bone-borne distraction device and first clinical results

“…While distraction of the ascending ramus (Tuzuner-Oncul and Kisnisci, 2011), the mandibular corpus (Iatrou et al, 2010) and the mandibular symphysis (Seeberger et al, 2011) are widely accepted techniques, segmental distraction osteogenesis of the anterior mandibular process is rarely found in literature.…”

“…An alternative surgical technique in the treatment of severe dental incisor crowding is mandibular symphyseal distraction (Seeberger et al, 2011) but this is mainly used in cases of a transverse mandibular width deficiency. In cases of dento-alveolar decompensation the technique of "orthodontic microsurgery" as introduced by Bertossi et al (2011), offers the opportunity to correct dental malposition without leading to unfavourable dental tipping.…”
