A Comparison of Two TAD Techniques (Miniscrews Versus Miniplates) for Treating Class III Malocclusion and The Associated Skeletal and Dental Effects

James Chen, Jesus I. Patino, Jenny Zwei-Chieng Chang, Chung-Chen Jane Yao, Ib Leth Nielsen

The aim of this study was to compare two different techniques for distalizing the mandibular dentition
in patients with Class III malocclusion using either miniscrews or miniplates. We evaluated the skeletal and
dento-alveolar changes associated with each method. The study also aimed at identifying cephalometric
characteristics in the subjects associated with the most predictable, successful outcome of treatment.

Validating the 3D and 2D Mandibular Plane to the Frankfort Plane for Craniofacial Measurement

Jason Jyun-Chen Kuo, Ellen Wen-Ching Ko

Purpose: This study evaluated whether the three-dimensional (3D) plane-to-plane mandibular plane angle measurement method could be applied in clinical analysis in a manner similar to the application of conventional two-dimensional (2D) cephalometric measurement, regardless of whether patients had symmetrical planes.

A Comprehensive Diagnostic System for Orthodontists-Beyond Angle's Classification

Ib Leth Nielsen

Traditionally orthodontists have used the classification system developed by Edward H. Angle in 1900
to describe the malocclusion of an orthodontic patient. This classification is very limited with respect to the
information it provides and should be replaced by a more detailed and inclusive description of a patient’s
malocclusion as well as the underlying biology. In this review article we propose a new technique that ensures
all pertinent information gets considered and we suggest a systematic approach to a more differentiated
orthodontic diagnosis. Our approach divides the diagnosis into clearly defined categories that bring together
the clinical findings into a comprehensive diagnosis.

Unusual Skeletal Growth of an Adult Patient with Acromegaly: A 12 Year Follow-up After Orthognathic Surgery

Szu-Ching Lee , Shou-Hsin Kuang, Yu-Shu Yen, Shen-Chieh Lina, Tzu-Ying Wu1

Acromegaly is an uncommon endocrinological disorder, which is rarely seen in patients presenting for
orthodontic treatment. Herein, we report a patient who underwent orthognathic surgery and was diagnosed
with acromegaly during the retention phase. During disease progression and treatment, gradual changes in
the mandible and facial soft tissue were detected. General information and management of acromegaly are
reviewed, and the role of orthodontists in the treatment of patients with acromegaly is discussed.

Management of Patient with Euryprosopic Face and Upper Central Diastema

Chung-Teng Chang, Yi-Min Liu, Yuen-Yung Tsang, Huei-Mei Tsai

An adult female has upper central diastema complicated with a complete deep bite and spacing in lower
dentition. The broad face and ovoid shaped dental arch form require special attention as an intrinsic transverse
dimensional skeletal malocclusion. The treatment modality therefore should be totally different from other
deep bite cases with crowding or tapered dental arch. The space retention after active treatment is of prime
important. Root divergence of upper incisors and bodily protraction movement of lower posterior teeth were
the main concerns during treatment. Fixed lingual retainer and long term follow up are essential for stable
outcome.
