Recent years, the trend of encounter rate of Orthodontics in adult is increasing, especially most of lingual orthodontic patients are adult.
Working as a staff in busy clinic, it was not easy to keep track of patient's various information, so we tried to develop a new system that computerize all the information of patients, and easy to understand information in a split second.
At reception, we introduced new system that enables managing of appointment, patient's information, and information transmission not only from clinic LAN systems, but also from remote operation.
We also introduced Dental X (planet inc.) system for hygiene instruction and uniform management of test results and oral pictures, by using chair-side PC or i-Pad.
Moreover, we developed the electronic medical record for Orthodontics ORTHO-REX in concern with RECS company, it made us lag-less share of information and delicate supplement that could not be made by ordinary analog records.
The inter-linking of these three systems could freed us from complicated work, so we had enough time to talk with our patients.
This lead to enrich and reliable provision of information, also decrease troubles.

Improvements in the customized base design and the bonding system have allowed development of a precise direct bonding system, named KommonBase. KommonBase is characterized by a large bonding base, which can acquire the best fitting and a precise bracket positioning while also enhancing bond strength. There is no need to use transfer trays because of its self-positioning shape.
Morphological complexity of lingual surface is a great advantage for applying KommonBase. There are many landmarks on lingual surface of the teeth; cingulum, marginal ridge, lingual groove, etc. KommonBase can achieve seating of bracket position according to the landmarks.
Brackets can be positioned easily and accurately by pressing the brackets with explorer. If the bracket is laid on incorrect position, KommonBase can direct it to a correct position. Most part of KommonBase spread over the lingual surface of the teeth consists of KommonBase resin LV. This extended resin was very thin like a film. Even in the case of occlusal interference, interfered resin can be grinded automatically according to the function of occlusion.
KommonBase should be bonded firmly throughout orthodontic treatment, and it also should be removed easily at the end of treatment. Hybrid ionomer is superior alternative for the bonding of lingual orthodontic brackets. The bond strength of hybrid ionomer is not affected by contamination of saliva and water.

In lingual orthodontics, we often need the custom set up model for indirect bonding system.
To make the custom set up model , we have to do more accurate diagnosis and to decide treatment plan.
My conception for the accurate set up model is to use the model, it was mounted in centric relation and to use the articulator with adjusted condylar controls.
This time, I report the 2 cases by the Lingual Core system using the manual set up model with the articulator adjusted condylar controls.

There are Patients who causes inflammation in the inside of lingual orthodontic treatment.
I am thinking those that as the cause, inflammation does not disappear in many cases, it only brushes positively.
1: The place which is not visible from the front is equipped with equipment, it is hard to take a dental plaque.
2: It is easy to increase accumulation of a dental plaque between a bracket and gum for adhered near gingival.
3: In brushing technology, a difference exists by an individual.
4: There is a patient who gets gingivitis easily, the difference in a host's bacteria and the reaction. For example , cause bacteria of gingivitis and periodontitis are existed in the mouth.
It said that gingivitis and periodontitis are the infection by bacteria , perio medical treatment was perfomed. perio basic medical treatment. (with life style instruction, brushing instruction, scaling, partial medication of antibacterial medicine)
After, change of probing depth of gingival was investigated and the improvement of inflammation was accepted.

The patient was a 27year and 7months old female patient when treatment first commenced. The chief complaint was the upper anteriors crowding. The molar relation was Angle ClassⅡand the overjet was＋7.2mm. Cephalometric analysis showed ANB of ＋9.6°and lessgrowth of mandible. Upper and lower central incisors were flaring. The patient was diagnosed with Angle ClassⅡ malocclusion division 1 with lessgrowth of mandible and crowding. Non-extractin of the lower bicuspids was planned initially in order to correct of overjet , however, the treatment performed with the extraction of two upper first premolars and two lower second premolars because of the upper and lower central incisors were flaring and the lower arch discrepancy were －5.2mm.The patient was treated using palatal bar and elastics for the correction of Angle Class Ⅱ molar relation. Active treatment time were 31 months. Stable occlusion and good function have been maintained for 3 years 10 months post-treatment.
