INTRODUCTION Disc displacement without reduction with limited opening is an intracapsular biomechanical disorder involving the condyle-disc complex. With the mouth closed, the disc is in an anterior position in relation to the condylar head and does not reduce with mouth opening. This disorder is associated with persistent limited mandibular opening. CASE REPORT The patient presented severe l...

Introduction: Angle and internal position of lateral pterygoid muscle leads to contraction over two half of the mandible in maximum opening and protrusion position so it can affects impression prosthetic procedures. The aim of this study was to evaluate the mandibular flexure in two transverse and antro-posterior dimensions. Methods: Seventy edentulous patients at Mashhad Faculty of Dentistry a...

OBJECTIVE To assess rotation and translation movements of the mandible at maximum mouth opening in a group of patients successfully rehabilitated after condylar fractures. MATERIALS AND METHODS Using a three-dimensional motion analyser, free movements of mouth opening were recorded in nine patients, and divided into their rotation and gliding components. Surface electromyography (EMG) of the ...

Microstomia is a term used to describe a small oral aperture, which is different from micrognathia in which patients have small jaws. The term microstomia may be better defined as any restriction in the range of motion of the mandible, so it is functionally reduced mouth opening. Normal maximum mouth opening ranges from 36-77mm in healthy individual with average value of 40-50mm. Abstract: Stat...

INTRODUCTION Temporomandibular disorders (TMD) lead to masticatory muscle pain, jaw movement disability and limitation in mouth opening. Pain is the chief complaint in 90% of the TMD patients which leads to disability and severe socioeconomic costs. The purpose of this study was to evaluate the therapeutic effects of low level laser therapy (LLLT) compared to pharmacotherapy with NSAIDs (naprox...

OBJECTIVE To estimate active maximum mouth opening (AMMO) in a Jordanian subpopulation and to study associated factors and relationship to patient's dental conditions. METHODS This cross-sectional study was conducted on 496 patients aged 15-80 years at the University of Jordan Hospital, Amman, Jordan between October 2008 and March 2009. The AMMO was measured as maximum distance between incisa...

PURPOSE The aim of this study was to evaluate the relationship between the width of 3 or 4 fingers of one hand and maximum mouth opening (MMO) in healthy subjects. METHODS One hundred and forty dental students (age 21 to 42 years, mean 27.4 years) participated in the study. The ability of each subject to position 3 or 4 fingers, vertically aligned, between the upper and lower central incisors...

abnormal elongation of the mandibular coronoid process is rare and its etiology is not yet elucidated. the aim of this report is to demonstrate and discuss the relationship between elongated mandibular coronoid process and limitation of mouth opening with cone beam computed tomography. although the clinical characteristic of elongation of the coronoid process is mandibular limitation, in this r...
