This article describes the orthodontic treatment for a young woman, aged 23 years 5 months, with a Class III malocclusion and a deviated midline. Two orthodontic mini-implants (C-implants, CIMPLANT Company, Seoul, Korea) were placed in the interdental spaces between the mandibular second premolars and first molars. The treatment plan consisted of(More)
OBJECTIVE The purpose of this study was to assess new three-dimensional (3D) cephalometric variables, and to evaluate the relationships among skeletal and dentoalveolar variables through 3D cephalometric analysis. METHODS Cone-beam computed tomography (CBCT) scans were acquired from 38 young adults (18 men and 20 women; 22.6 ± 3.2 years) with normal(More)
The purpose of this study was to compare preferred facial profiles rated by different age groups. An average profile of each gender was constructed from subjects with normal occlusions. Each average profile was located in the centre, and then the lips were protruded or retruded in six 1mm increments in each direction. 70 lay people were divided into 3(More)
OBJECTIVES The aim of this study was to analyse the displacement and stress distribution in the maxillofacial complex during maxillary protraction with buccal and palatal plates using three-dimensional finite element analysis. MATERIALS AND METHODS Three anchorage appliance models-palatal plate (Type A), miniplate at the infrazygomatic crest (Type B), and(More)
INTRODUCTION Our objective was to evaluate the factors that affect effective torque control during en-masse incisor and canine retraction when using partially osseointegrated C-implants (Cimplant, Seoul, Korea) as the exclusive source of anchorage without posterior bonded or banded appliances. METHODS Base models were constructed from a dental study(More)
This paper describes the treatment of a female patient, aged 23 years and 5 months, with a Class II division 1 malocclusion, who showed severe anterior protrusion and lower anterior crowding. Specially-designed orthodontic mini-implants were placed bilaterally in the interdental space between both the upper and the lower posterior teeth. Both lower first(More)
OBJECTIVE The purpose of this study was to investigate the relationship between the mandibular dental and basal arch forms in subjects with normal occlusion and compare them with those of Class III malocclusion using cone-beam computed tomography (CBCT). METHODS CBCT images of 32 normal occlusion (19 males, 13 females; 24.3 years) and 33 Class III(More)
OBJECTIVE To evaluate the therapeutic effects of a preformed assembly of nickel-titanium (NiTi) and stainless steel (SS) archwires (preformed C-wire) combined with temporary skeletal anchorage devices (TSADs) as the sole source of anchorage and to compare these effects with those of a SS version of C-wire (conventional C-wire) for en-masse retraction.

OBJECTIVE This study aimed to evaluate the effect of an intentionally created socket on bone remodeling with orthodontic tooth movement in rabbits. METHODS Eighteen male rabbits weighing 3.8 - 4.25 kg were used. An 8-mm deep and 2-mm wide socket was drilled in the bone 1 mm mesial to the right mandibular first premolar. The left first premolar was(More)
In this article, we describe the treatment of a woman, aged 25 years 8 months, with a Class II malocclusion, severe anterior protrusion, and a high mandibular plane angle. The treatment plan consisted of extracting both maxillary first premolars and mandibular second premolars. En-masse retraction of the 6 maxillary anterior teeth was performed with a(More)
