Compression osteosynthesis mandible

Plates with basal grooves and locating pins which grasp the lingual side of the mandible are available for extra-oral approaches. Plast Reconstr Surg ; The growth of bone tissue in any case represents an improvement: The effects of a tooth in the fracture line as a cause of infection can be minimized by preoperative antibiotic therapy.

The main methods used to correct mandibular hypoplasia are osteoplasty and compression—distraction osteosynthesis CDO [6—13]. Horizontal Distraction Allow activation intraoral distraction of up to 30 mm in length, for the growth of bone in the ramus and mandibular body.

Hippocrates was the first to describe reapproximation and immobilization through the use of circumdental wires and external bandaging.

J Oral Maxillofac Surg ; Most fracture treatment, however, involved some form of external bandage or wrap, occasionally used in conjunction with a bridle wire, until the 19th century, when Gilmer reformed the treatment of fractures by fixated full arch bars on the mandible and the maxilla.

In implant heads, was done 4 months later, and the final the comparison of the posteroanterior cephalograms prostheses were fabricated Figs 10 and The ligature based on Ernst is a figure-eight ligature placed around two adjacent teeth, preferably including the premolars and first molar.

Ideally, two pins with a large distance between them should be placed into each large segment to prevent rotation. After adaptation of the ligatures, the metal arch bar and ligature ends are reinforced with self-curing acrylic.

Mandibular fractures are among the most common skeletal injuries occurring in human beings. Materials and methods Compression—distraction osteosynthesis was used to treat 69 children ranging in age from 2 weeks to 15 years with congenital 37 patients with Goldenhar and Franceschetti syndromes, Robin syndrome or acquired 32 patients with traumatic or inflammatory temporo-mandibular joint arthrosis and ankylosis microgenia, which was bilateral in 41 cases.

The physiologic motion of the temporomandibular joint is a rotational-gliding motion, which is directed by the coordination of the muscles of mastication stomatognathic system. Retrospective analysis of data from medical records. Therefore maxillofacial surgeons, dentists and orthodontists alike seek simple solutions, economic and, in turn, reliable.

The entire structure of the mandible is comprised of a solid skeletal construction basilar archextending from the coronoid and condylar processes, over the rami and body, to the chin—allowing insertion of masticatory and tongue muscles—and a periodontal component alveolar process.

33: Principles of Fixation for Maxillofacial Trauma

Cases in which surgical exposure of fracture sites may interrupt blood supply, such as severely comminuted fractures or contaminated wounds, pose a risk for hardware infection and may be an indication for skeletal pin external fixation.

This can be ultimately converted to internal plate fixation to avoid prolonged skeletal pin hardware application. Therefore, each patient underwent dynamic US evaluation consisting of 7—10 exams.

Iizuka et al, [7] also noted infection as an important complication and suggested that it can be reduced by experience of the operator. Risultati Sono stati rilevati e descritti i segni ecografici equivalenti al tessuto di rigenerazione per distrazione DRnormotrofico, ipertrofico e ipotrofico.

The joint capsule is attached to the articular disk. Fracture segments can be reduced using various methods, including bone reduction forceps, manual anatomic reduction, interdental fixation, and a combination of these.

Osteosynthesis systems for the treatment of mandibular fractures

The plate is adapted to the mandible such that the fracture gap is positioned between the two eccentric holes. In all patients from group I, passive radiological controls were carried out during the entire CDO cycle.

However, the labiolingual thickness and the vertical orthodontic archwire, and elastomeric traction. Superimposition of pretreatment black line nuity in bony defect areas, create the anterior curvature and posttreatment red line lateral cephalogram of the alveolar bone, and provide good-quality regen- tracing.

Mandibular fractures occur as simple, double, or multiple factures, often together with midfacial fractures. Stabilisation of a fracture also requires thick plates with bicortical screws along the lower border.

Full Text Abstract Objective: Therefore, the second option was se- lected for this patient. Introduction Congenital or acquired hypoplasia of the mandible leads to esthetic problems and dental—maxillary disorders associated with various medical, psychological, and social problems [1—5].

Compression osteosynthesis implies the use of rigid fixation across a fracture or osteotomy so that the fragments are compressed together even when the body part is at rest (no functional load).

Traditional Methods vs Rigid Internal Fixation of Mandible Fractures

It must be applied in such a way that the addition of a functional load will not reverse the compressive force.

These techniques contradicted the AO and Luhr's emphasis on compression and absolute rigidity. Champy later performed a series of experiments with miniplate that delineated “ideal lines of osteosynthesis” within the mandible. Plates placed along these lines were thought to provide optimal fixation and stability [Figure 1].

Ideal plate. The present study was aim to determine the effectiveness and the advantages of non compression miniplate osteosynthesis at upper border of mandible along champy's lines of osteosynthesis.
