In the treatment of orthodontic patients with idiopathic condylar resorption, symptoms of temporomandibular joint disorders and constantly changing occlusions caused by an instability of mandibular position make it difficult for orthodontists to confirm definitive orthodontic diagnosis and treatment plans. Therefore, these patients' temporomandibular joint (TMJ) structures need to be stabilized with splint therapy before active tooth movement to identify and maintain the true mandibular position. For some idiopathic condylar resorption patients, orthognathic surgery can cause further resorption on the vulnerable condyles of the mandible; thus, effective orthodontic camouflage treatment after joint stabilization should be considered. During the orthodontic camouflage treatment, adverse loads on the TMJ structures, which could change the position of condyles, should be avoided, and TMJ-friendly mechanics must be applied.

Purpose Of The Study: Temporary hemiepiphyseodesis using figure-eight plates is currently one of the main surgical techniques to correct axial deformities of lower limbs in paediatric patients. Comprehensive analysis, correct indication and monitoring of treatment are the basic prerequisites for successful therapy. The aim of the study was to analyse parameters that could become an alternative to standard parameters used nowadays, namely the inserted screw angle (SA), and a new parameter - condylar ratio (CR).

Objective: In this study, we aimed to establish an experimental model of idiopathic condylar resorption by combining surgically induced anterior disc displacement and estrogen deficiency in growing rabbits. This study aimed to investigate the individual and combined effects of these factors on condylar resorption.
Materials And Methods: Seventeen female Japanese White rabbits were divided into four groups: control, ovariectomy, anterior disc displacement surgery, and combination of ovariectomy and anterior disc displacement surgery.

Background And Objectives: Idiopathic condylar resorption (ICR) can be described as a dysfunctional remodeling of the temporomandibular joint (TMJ). It is clinically characterized by morphological changes in TMJ including reduced ramus height, accelerated mandibular retrusion and reduced growth in juveniles. With a strong predilection towards females (90 %) within an age group of 10 to 40 years, diagnosis and management of ICR is a critical clinical challenge.

Background: Idiopathic condylar resorption (ICR) is a rare condition of unknown etiology characterized by progressive decrease in volume and pathologic remodeling of a previously normal mandibular condyle. Juvenile idiopathic arthritis (JIA) affecting only the temporomandibular joint (TMJ-only JIA) is characterized by synovitis and destruction of TMJ tissues without involvement of other joints. It is often difficult to differentiate the 2 conditions because they exhibit similar phenotypes.
