What are the risks of leaving osteosynthesis material …

The relatively simple procedure for removal of osteosynthesis material facilitates the decision for or against removal for the surgeon, and is an advantage over other functionally stable methods for osteosynthesis.
An extremely narrow or curved mandible is considered a contra-indication for lag screw osteosynthesis because in these cases the gliding canal is not sufficiently covered laterally with cortical bone (Welk and Sümnig 1999).

What Is Osteosynthesis Material

(2002) recorded connections between clinically and/or axiographically determined limitations their patients suffered, and the kind of osteosynthesis material used.

Another option is to remove the plate via an oral approach with transbuccal removal of the screws.
Biomechanically, miniplate osteosynthesis is not the ideal method due to the position of the plate at the lateral margin of the mandibular ramus.

Pre-auricular approach

If a pre-auricular approach is selected, the condylar neck is exposed first and then the condylar head is located.

partially edentulous jaw)If osteosynthesis is required for fixation of fragments, mini-plates or micro-plates are used.

It is important to ensure that the screw is inserted into an area of the condylar head such that it will not be in the way of subsequent osteosynthesis plates and screws.

Fixation of osteosynthesis plates with screws in healthy bone away from inflamed tissues is essential in these cases.

Definition of Osteosynthesis - MedicineNet

Strain is the deformation of a material (eg, granulation tissue within agap) when a given force is applied. Normal strain is the change in length (Δ l)in comparison to original length (l)when a given load is applied. Thus, it hasno dimensions and is often expressed as a percentage. The amount of deformationthat a tissue can tolerate and still function varies greatly. Intact bone has anormal strain tolerance of 2% (before it fractures), whereas granulation tissuehas a strain tolerance of 100%. Bony bridging between the distal and proximalcallus can only occur when local strain (ie, deformation) is less than theforming woven bone can tolerate. Thus, hard callus will not bridge a fracturegap when the movement between the fracture ends is too great [22]. Nature dealswith this problem by expanding the volume of soft callus. This results in adecrease in the local tissue strain to a level that allows bony bridging. Thisadaptive mechanism is not effective when the fracture gap has been considerablynarrowed so that most of the interfragmentary movement occurs at the gap,producing a high-strain environment. Thus, overloading of the fracture with toomuch interfragmentary movement later in the healing process is not welltolerated [23].

Furthermore, their patients suffered limitations following the use of plating systems for osteosynthesis (miniplates, microplates).

Clinically, scarring of the capsule and ligaments has been observed in the course of necessary removal of osteosynthesis material, particularly in the case of loosening of material and/or screws.

Here, compression osteosynthesis is always preferable to mini-plate osteosynthesis (Prein and Schmoker 1989, Luhr et al.
