A study was conducted to compare the effectiveness of the crib and positive reinforcement in eliminating anterior open bites and increased overjets caused by digit-sucking. The overjet and overbite were measured using an overjet ruler at the start and end of the seventeen-week observation period. Forty patients consented to participate but measurements were only obtained for 11 subjects. The tr...

Unilateral closure of maxillary extraction spaces in patients with Class III malocclusion can be challenging. This case report describes the closure of first premolar and first molar extraction spaces in a patient with a Class III dental relationship. Two miniscrews were used for intraoral skeletal anchorage. The Class III dental relationship was corrected; a positive vertical overbite was achi...

background: the purpose of this study was to compare the occlusal peer assessment rating (par) index in class i patients treated by means of begg and edgewise methods. materials and methods: the pre- and post-treatment study models of class i patients, referred to two private clinics, treated with begg method (n = 30) and standard edgewise method (n = 30), were reviewed retrospectively using pa...

OBJECTIVE We compared the skeletal and dental changes that resulted from the use of two methods of intermaxillary fixation (IMF)-miniscrews and surgical archwire-in 74 adult patients who had Class III malocclusion and were treated with the same orthognathic surgical procedure at a hospital in Korea. METHODS All the patients underwent Le Fort I osteotomy and bilateral sagittal split ramus oste...

The stomatographic system has been studied by several researchers, yet it is still unclear, weather a genetically determined facial morphology decides the strength of masticatory muscles,(1) or weather a strong musculature influences the form of the face. This formed the basis of present study to relate muscle activity with various malocclusions. Thus, 60 samples of younger age group were divid...

In the present report, we describe the successful use of miniscrews to achieve vertical control in combination with the conventional sliding MBT™ straight-wire technique for the treatment of a 26-year-old Chinese woman with a very high mandibular plane angle, deep overbite, retrognathic mandible with backward rotation, prognathic maxilla, and gummy smile. The patient exhibited skeletal Class II...

Skeletal changes greater than those observed in untreated adults have been noted beyond 1 year post-surgery in adult patients who had surgical correction of a long face deformity. The stability of skeletal landmarks and dental relationships from 1 to >3 years post-surgery was examined in 28 patients who had undergone surgery of the maxilla only, and in 26 patients who had undergone 2-jaw surger...

The effect of vertical dimension of occlusion (VDO) on maximizing isometric deltoid strength (IDS) was measured in subjects with deep overbite. Sixteen female dental students with deep dental overbite and no history of temporomandibular joint disorder (TMD) were used as their own control and tested for isometric strength of the deltoid muscles, using a hand held strain gauge. Measurements were ...
