The purpose of this study was to establish a Japanese standard norm for orthognathic surgical analysis to be used in clinical applications and to clarify maxillofacial morphological characteristics in skeletal Class III malocclusions requiring orthognathic surgery. The materials were pretreatment lateral cephalometric radiographs in the relaxed lip posture from 50 subjects with skeletal Class I...

INTRODUCTION Chin cup (CC) therapy has been used as the traditional appliance for treating class III malocclusion during mixed dentition period. The aim of this study was to investigate the effect of CC on the improvement of skeletal and dentoalveo-lar skeletal changes in class III patients during mixed dentition stage. MATERIALS AND METHODS A total of 30 patients (7-9 years old) with skeleta...

Objective: The objective of this study is to assess the relationship anterior and posterior occlusal planes (AOP & POP) with Sella-Nasion (SN) Frankfort Horizontal (FH) in different skeletal malocclusion. Study Design Setting: It was a cross-sectional carried on 202 (40 males 190 females) pretreatment lateral cephalogram orthodontic patients Jinnah Medical Dental College, Karachi from June ...

INTRODUCTION Prognosis is the main limitation of interceptive treatment of Class III malocclusions. The interceptive procedures of rapid maxillary expansion (RME) and face mask therapy performed in early mixed dentition are capable of achieving immediate overcorrection and maintenance of facial and occlusal morphology for a few years. Individuals presenting minimal acceptable faces at growth co...

AIM Distraction osteogenesis (DO) is a treatment option for patients with maxillary hypoplasia secondary to cleft lip and palate (CLP). PURPOSE The aim of this study is to present a technique for maxillary DO using Le Fort I osteotomy with rigid external distraction (RED) system. SUBJECTS AND METHODS The patient presented in this paper was an Asian female with CLP aged 13 years and 6 months...

BACKGROUND The role of ankyloglossia in etiology of malocclusion is not much discussed over the years. The aim of the present study was to assess the skeletal and dental characteristics in subjects with ankyloglossia. METHODS Fifty-seven subjects diagnosed with ankyloglossia (group 1) were compared with 60 subjects (group 2) without ankyloglossia, who had class I skeletal base. Ankyloglossia ...

Objective: The aim of this study was to compare the effect of face mask (FM) and Maxillary Bite Block (BB) in skeletal class III patients during mixed dentition with control group of the same class during their growth. Materials & Methods: Forty-two patients were selected based on clinical and cephalometric examination, with age ranged from 6 to 8 years according to definite criteria. Patients ...
