PURPOSE This study was conducted to compare the time-course changes in condylar long-axis and skeletal stability after sagittal split ramus osteotomy (SSRO) with bicortical plate fixation versus monocortical plate fixation. PATIENTS AND METHODS Of a group of 40 Japanese patients diagnosed with mandibular prognathism, 20 underwent SSRO with bicortical plate fixation using a locking plate syste...

purpose: to compare the results of implantation of intraocular lens (iol) haptics in ciliary sulcus versus optic capture through the posterior capsulorrhexis following iol implantation in capsular bag in pediatric cataract surgery. methods: eighteen eyes of nine children with bilateral congenital or developmental cataract were included in this contralateral prospective randomized study. all cas...

This study pertains to a random sample of untreated French-Canadian adolescents (79 females and 107 males) evaluated at 10 and again at 15 years of age. Superimpositions on natural reference structures were performed to describe condylar growth and modelling of 11 mandibular landmarks. Superimpositions on natural cranial/cranial base reference structures were performed to describe mandibular di...

OBJECTIVE To assess the intra-rater and inter-rater reliability for measuring femoral anteversion angle (FAA) by a radiographic method using three-dimensional computed tomography reconstruction (3D-CT). METHODS The study included 82 children who presented with intoeing gait. 3D-CT data taken between 2006 and 2014 were retrospectively reviewed. FAA was measured by 3D-CT. FAA is defined as the ...

PURPOSE The purpose of the present study was to analyze the effect of clenching on the biomechanical response of human mandible and temporomandibular joint (TMJ) to traumatic force by the finite element (FE) method. MATERIAL AND METHODS FE models of the mandible and the TMJ in resting and clenching positions were prepared. Distribution and magnitude of von Mises stress were analyzed by applyi...

The purpose of this retrospective study was to analyze changes in the position condyles following mandibular setback surgery with manual guidance. included 28 patients prognathism who underwent using guidance a bioabsorbable mesh for fixation, and center condylar head were compared at three time points: before (T0), within 1 week after (T1), 6 months (T2). results showed significant lateral, an...

OBJECTIVES Posterior condylar offset (PCO) and posterior tibial slope (PTS) are critical factors in total knee arthroplasty (TKA). A computational simulation was performed to evaluate the biomechanical effect of PCO and PTS on cruciate retaining TKA. METHODS We generated a subject-specific computational model followed by the development of ± 1 mm, ± 2 mm and ± 3 mm PCO models in the posterior...

OBJECTIVES/HYPOTHESIS We hypothesized that children with isolated nonsyndromic unilateral congenital aural atresia have subclinical mandibular condylar hypoplasia ipsilateral to the atretic ear, and that the Jahrsdoerfer score is associated with the degree of condylar hypoplasia. STUDY DESIGN Retrospective self-controlled case series. METHODS We reviewed high-resolution computed tomography ...
