A shorter latency period was suggested to be sufficient for the early stage of healing process because the craniofacial bones have a rich vascular supply. There are number of variables which modify the protocol such as less time necessary for optimal hard and soft tissue response in younger patients.

It is generally suggested that distraction forces leading to cellular deformation are signalled to the cellular genome through mechanotransduction. Int J Oral Maxillofac Surg.

The Incision to access the bone must be conservative in length, with minimal dissection of the periosteum to ensure good blood supply close to the osteotomy site. Br J Oral Maxillofac Surg. Abstract An attempt has been made to review various devices as well as the outstanding studies done in the past for understanding the methodology of distraction for regeneration of bone. Report of a case using a new device.

Conversely, rh-BMP-2 was effective in enhancing consolidation when applied as solid or liquid phase at day 0 and at the end of distraction. This comprehensive, full-color text presents the latest information on extraoral and intraoral distraction appliances, including tooth-borne, bone-borne, and hybrid fixation methods. Alterations of morphology and microdensity in the condyle after mandibular osteodistraction in rat.


Bone regeneration within a human segmental mandible defect: Br J Oral Samchukv Surg. This allows surgeons, the lengthening and reshaping of deformed bone. Distraction osteogenesis of the human craniofacial skeleton: Molecular events and mechanism of bone formation in distraction osteogenesis in humans. The initial development of intraoral mandibular distraction devices progressed in two directions 1 miniaturization of external devices, 2 modification of available orthodontic devices.

Craniofacial Distraction Osteogenesis

A proliferative response may contribute to improved long-term stability of mandibular xraniofacial by distraction osteogenesis. This phase usually lasts weeks, and the traction modifies the normal development of the regeneration process. New techniques of bone skull defect substitution. This has led to an evolution of various distraction devices from bulky extraoral to miniaturized submerged intraoral devices.

Do position and soft tissue affect distraction vector? Intraoral mandibular distraction osteogenesis. Effects of distraction forces and frequency of distraction on bony regeneration. J Bone Joint Surg Br.

Craniofacial Distraction Osteogenesis : Alexander M. Cherkashin :

Cutaneous scars are associated with external distractors and occur in the path of pin movement [ Figure 5 ]. Sagittal ramus osteotomy for use in intraoral distraction osteogenesis in primates.

Alveolar ridge distraction An intriguing application of the bone transport technique is the augmentation of the maxillary and mandibular alveolar ridges. Midface surgery from Tessier to distraction.

Dietraction attached to the bone are bone-borne; to the teeth are tooth-borne or attached to the teeth and bones are the hybrid type of distraction appliances. The complications of distraction can be studied by dividing them into two categories, technical complications and general complications.

They can be placed above i. Concluded that position alone had minimal effects on distraction vector.

Unfavourable results with distraction in craniofacial skeleton

Hypotrophic regenerate A hypotrophic regenerate is characterised by delay or lack of mineralisation of the distraction gap [ Figure 4 ]. Paris, France, Bologna, Italy: A variety of cephalometric analyses are available to map the precise location and extent of the deformity.


The distraction device should be secured using the anchoring pins and a test distraction should be performed intraoperatively to make sure that the fixation of the device and the osteotomy is complete.

Effect of rhythm and level of distraction on muscle structure: Case Reports; Distraction Osteogenesis: The post-distraction complications centre around the failure to achieve the planned result. Right and left maxillary and mandibular distractors are separately available.

Skin, blood vessels, nerves, muscle, ligament, tendon, and cartilage.

Unfavourable results with distraction in craniofacial skeleton

Am J Orthod Dentofacial Orthop. Cranial Distraction Distraction osteogenesis is a powerful tool for surgical reconstruction of complex deformities.

The present study analyses the current standards and techniques of distraction and details in depth the various errors and complications that may occur due to this technique. Depending on the direction of lengthening, devices have been classified as unidirectional, bidirectional, or multidirectional devices. Force-displacement behaviour of biological tissue during distraction osteogenesis. Technical considerations in distraction osteogenesis.

Support Center Support Center. Failure to recognise this leads to undue stress on the fixation pins culminating in either loosening of samcchukov pins at the site of bone craiofacial or loosening of the pins at their site of distractor clamp anchorage.
