The bond failure rate of the full custom lingual bracket appliance system

Aya Hayashi, Goshi Ito, Yuko Nakano, Toru Inami

Released: June 22, 2016

p.4-12

Objective
In case of lingual orthodontic treatment, the bonding failure is serious problem because orthodontists can not bond the bracket correctly. The purpose in this study was to evaluate the bonding failure rate using Incognito system.
Material and Methods
42 patients (7 male, 35 female) were treated with Incognito system in Inami orthodontic office. We studied to each patients about some items: bonding failure times, the kinds of teeth falling off the bracket, the rates of bonding failure in each teeth, the characters of teeth surface, the shape of bracket base and the kind of cement using at initial bonding.
Results
The average number of bonding failure times in all patients was 2.3 times. 43% patients of the total did not fallen off the bracket once. The bonding failure rate was the highest at the molars in upper and lower jaw. The restoration tooth showed higher rate of bonding failure than natural tooth. Furthermore, the bracket types of band and pad exhibited lower rate than narrower type of bracket base.
Conclusion
Bracket failure occurred easily in the part of molars and repaired tooth. Therefore, to prevent the bracket falling off, it is necessary to order a wide bracket base as possible and make some additional treatments before bracket bonding such as drilling the undercut when the tooth surface is repaired.

Teeth Bank - Autotransplantation of tooth-

The patient was aged 38 years and 3 months old at the first visit. Although the upper left wisdom tooth had fully erupted, occlusion could not be achieved due to the extracted opposing tooth. Therefore, the wisdom tooth was extracted for use in the present study.
Dental X-ray was taken before extraction, and the donor tooth was polished. Xylocaine with 1:80,000 epinephrine was used as local anesthesia. Extraction was performed using only forceps with diamond particles. The extracted tooth was placed in a polypropylene container and immersed in preservative solution. The tooth in the solution was then frozen in a programmed freezer with a magnetic field. After the donor tooth had been frozen, it was preserved for 4 days in an ultracold freezer at -150°C. It was naturally defrosted at room temperature of 22°C directly before transplantation.
Root canal filling was performed with calcium hydroxide paste 30 days after transplantation. After autogenous transplantation of the frozen tooth, the periodontal membrane was regenerated, and the prognosis was satisfactory.
This article will discuss guidelines from the periodontal perspective to evaluate the treatability of periodontally compromised adult orthodontic patients.

Facial change produced with the intrusion of the upper and lower dentitions using 4 anchor screws in an Angle Class II Division 1 case.

An Angle Class II Division 1 case with a deep bite was treated with a lingual bracket system in combination with anchor screws placed in the upper and lower arches. The treatment allowed for not only Class II correction but also favorable occlusal and facial changes with the intrusion of the entire upper and lower dentitions and not just the anterior teeth.

Properties of non-surgical treatment in the mandibular protrusion.

p.33-48

Objectives
In Japan, there are many situations that necessitate changes in treatment plan from orthognathic surgery to orthodontics alone for various reasons. The objectives of this presentation are to present anterior crossbite cases treated with orthodontics alone based on computer simulations of orthognathic surgery and to discuss the dental, occlusal, and facial improvements achieved with the treatment.
Methodologies
Mandibular setback with sagittal split ramus osteotomy was proposed to both Case 1 and Case 2 during the initial consultation because of mild chin protrusion and anteriorly positioned B point. However, the patients opted for non-surgical treatment and were thus treated non-surgically by lingual orthodontics. Upper and lower premolars were extracted to move the upper molars mesially and retract the lower incisors by lingual tippling in order to obtain a positive overjet.
Results
While the anteroposterior position of the maxilla remained unchanged, the initial Angle Class III molar relationship was corrected to Class I in both cases with mesial movement of the upper molars using moderate anchorage. Because of the change in treatment plan from orthognathic surgery to non-surgical treatment, the lower incisors were retracted by lingual tipping, resulting in improved overbite and overjet.
Conclusions
Concave profiles were improved with orthodontics alone by changing the inclination of teeth. Lingual orthodontics, which provides strong mandibular anchorage and facilitates lingual tipping of the anterior teeth, can be an effective option to successfully treat patients who do not wish to undergo surgery.

A half lingual case of .018”×.025” slot brackets and .022”×.028” slot brackets were placed on the anterior teeth and canine, and the posterior teeth respectively , and the upper anterior teeth were retracted by sliding mechanics.

For lingual orthodontics treatment, it is considered difficult to control torque in the upper anterior for extraction cases. Various methods have been suggested in order to ensure torque control of the upper anterior region. The purpose of this paper is to report a desired treatment result: .018”×.025” slot brackets and .022”×.028” slot brackets were placed on the anterior teeth and canine, and the posterior teeth respectively, and the upper anterior teeth were retracted by sliding mechanics with .018×.025 stainless steel wire.

Lingual orthodontic treatment is a very attractive treatment method from the aesthetical point of view because appliances cannot be seen ,”invisible”, and the number of patients who want lingual orthodontic treatment is increasing year after year. The choices of lingual orthodontic treatment increase and the mechanics of the treatment progresses every day, too. JLOA holds Basic Typodont Course of Lingual Orthodontic Treatment every year in order to expand capability to understand biomechanics peculiar to lingual orthodontic treatment and to improve the expert skill without affected by kinds of appliances.　Lectures in the seminar programs are held by chapter division as emergency response and patient management including initial troubles that are prone to happen by lingual orthodontic treatment.

Complaint from a patient feeling tongue of the bracket when mounted a symptom of lingual orthodontic treatment-specific, pain, foreign body sensation, pronunciation failure, for swallowing function was heard from the beginning.
Fujita method Since its introduction in 1970's, a history that has been repeatedly improved development to design simpler the shape of the lingual bracket at present.
However, even if simplified, patient perception of individual vary, there is a difference between our operator side anyway, I need time to get used to.
So, before attaching the lingual bracket fixed, can be training the patient and also can experience in three dimensions the equipment fit, our correspondence prior pain, foreign body sensation, pronunciation failure, to the swallowing function．
We report a case devised a tray that can be.
