Hybrid Orthodontic Treatment System
HOTS
T. Ikegami DDS, MS Kumamoto, Japan

Hybrid Orthodontic Treatment System (HOTS) has been developed in the search of the most efficient and reliable treatment system by combining the following 3 orthodontic devices or methods which were developed independently with different treatment concepts.

1. Micro Implant Anchorage (MIA)
2. Combination wire
3. Multi-loop Edgewise Arch-wire (MEAW)

The most important feature of this system, compared with the conventional en-masse retraction in which 6 anteriors are retracted together, is that in this technique the canines are retracted along the corner curve of the canine area independently from the other 4 incisors. These 6 anteriors, however, are still retracted simultaneously. In this way, the canines can travel along the alveolar trough between the cortical bones. On the other hand, with the conventional en masse movement, canines may easily hit the lingual cortical bone as it is retracted straight backwards. Thus the distal movement of the 6 anteriors may not be as smooth as with the HOTS thereby causing more damage to the anterior teeth as well as to the lingual alveolar bone, which will result in extended treatment time.


HOTS Treatment Procedure

Step1. Extraction of bicuspids and insertion of MIA in one visit
Step2. Leveling with the .0155 or .0175 multi-stranded wire and the .016 Ti-Ni wire with “lace-back” retraction of the canines followed by final alignment with .016 x .022 Ti-Ni wire
Step3. Simultaneous retraction of canines, as well as 4 incisors, with combination (.017x.025 rectangular and .016 round) wire
Step4. Finalization with the MEAW (.016 x .022 Stainless steel wire)



Flow of HOTS


Ext. of first bicuspids and insertion of the MIA(2mo.)
↓
Levelling　of upper and lower arches (6 mo.)
↓
Retraction of canines as well as 4 incisors by a wonderwire (6mo.)
↓
Final overjet reduction and settling by MEAW (6mo.)

Total 20 months of treatment time

Radiographic Cephalometry: From Basics to Videoimaging



Radiographic Cephalometry: From Basics to 3-D Imaging, Second Edition

Alexander Jacobson, Richard L. Jacobson



Digitization of photographs, radiographs, and cephalometry has radically transformed the practice of clinical orthodontics. This important textbook, widely regarded as the definitive source on radiographic cephalometry, has now been updated and expanded to reflect these emerging technologic innovations. In addition to covering basic principles - including manual tracing techniques, landmark identification, and the traditional cephalometric analyses - this new edition describes the numerous applications of digital radiography, digital radiographic cephalometry, and 3-D cephalometric analysis for enhanced accuracy and efficiency in diagnosis and outcome prediction. Eight completely new chapters have been added on the advantages and drawbacks of 2-D versus 3-D analysis; the use of imaging in treatment planning; the value of electronic storage, analysis, and retrieval of all records; anteroposterior cephalometry; the first 3-D cephalometric analysis; and more. An accompanying CD-ROM containing a reproducible headfilm and templates, both for manual and digital cephalometry, as well as sample video clips is included with every book. This comprehensive text is ideal for both students and experienced professionals who wish to ******* and/or update their understanding of this subject.
