최근 교정치료가 진보함에 따라 치료대상이 성인에까지 폭넓게 적용되고 교정장치에도 심미성이 요구되어지고 있다. 이러한 요구에 부응하여 bracket과 attachment의 소형화, ceramic 또는 plastic을 사용한 투명도가 높은 장치가 개발되었다. 그러나, 순측 치면에서 bracket을 장착하는 치료에 있어서는 심미성에 한계가 있다. 이러한 점에서 lingual bracket은 설측 치면에 접착함으로써 성인교정에 있어서 심미적으로 우수하다고 할 수 있다. 이에 저자들은 lingual bracket을 이용한 교정치료에 있어서 새로운 기공과정과 임상과정을 확립하였기에 소개하고, 현재 많이 사용하고 있는 Ormco사와 Dr. Fujita의 lingual bracket을 이용하여 치료한 증례를 다음의 순서로 4회에 걸쳐서 보고하고자 한다.

Making a precise and ideal set-up model is an essential part in the indirect bonding procedure for lingual orthodontic treatment. To evaluate the accuracy of the making a set-up model, 22 adult patients who received lingual orthodontic treatment with 4 bicuspid extractions were selected, and 3 sets of dental models (before, set-up, and after treatment) were measured using the set-up model gauge, an instrument for measuring the inclination and angulation of the clinical crowns on the dental model. Two sets of lateral cephalograms (before and after) from each patient were also evaluated. The mean difference between the before treatment model and the set-up model was $-3.93{\pm}6.98^{\circ}$ for the inclination and $1.87{\pm}5.79^{\circ}$ for the angulation. And the mean difference between the set-up model and the after treatment model was $-4.31{\pm}5.91^{\circ}$ labiolingually and $-2.16{\pm}3.27^{\circ}$ mesiodistally, The after treatment model differed from the before treatment model about $-8.24{\pm}5.39^{\circ}$ in inclination. There were no significant difference between the measured gauge that measured from the dental model using the set-up model gauge and the calculated gauge angle measured from the lateral cephalogram using constructed points and lines. Using the set-up model gauge, it is possible to evaluate the study model 3-dimensionally in relation with the patient's lateral cephalogram and establish whether the doctor's prescription or overcorrection is built in the set-up model precisely.

This case report describes the treatment of a 23-year, 8-month-old female patient with a Class II malocclusion who showed severe bidentoalveolar protrusion and anterior crowding. The treatment plan consisted of extracting all the first premolars, decrowding and en masse retraction of the upper six anterior teeth and lower anteriors. The upper C-plate placed in the midpalatal area combined with lingual sheath fixtures were used as substitutes for posterior anchorage teeth during upper anterior retraction. Preadjusted brackets (0.022-inch) were used for upper anterior decrowding. A 0.9 mm diameter stainless steel lever-arm soldered to the main arch wire facilitated controlled retraction of upper anteriors. The upper and lower dentition was detailed using a tooth positioner during the finishing stage. Correct overbite and overjet were obtained by decrowding and retraction of the upper six anterior teeth into their proper positions. Use of the C-plate and lingual appliances provided ideal anchorage to enhance the improvement in facial balance. The active treatment period was 19 months. The treatment result was stable 13 months after debonding.

The purpose of this study was to evaluate the morphological changes of olveolar bone and mandibular symphysis of lower incisor by presurgical orthodontic treatment and orthognathic surgery in skeletal class III malocclusion. The sample consisted of 30 adult class III malocclusion patients who have received bilateral sagittal split mandibular osteotomy. Lateral cephalograms were taken before treatment, after presurgical orthodontic treatment and 3 months after orthognathic surgery. Skeletal and symphyseal measurements were compared and the relationships between them were analysed. The results were as follow : 1. The labial and lingual alveolar bone height in presurgical and postsurgical group were decreased than that of pretreatment group. 2. The vertical measurements of the craniofacial skeleton showed reverse correlationship with anteroposterior width of basal alveolar bone, but IMPA showed correlatiionship (p<0.01) 3. The craniofacial skeleton and the change of symphyseal measurements(symphyseal length, symphyseal width) showed no correlationship. 4. The labial alveolar bone height showed correlationship with lingual alveolar bone height(p<0.001), and negative correlationship with lingual alveolar crestal width(p<0.01). Labial and lingual alveolar crestal width has negative correlationship (p<0.05). Mandibular symphyseal length and width has positive correlationship(p<0.01). 5. IMPA, LISA showed negative correlationship with labiolingual alveolar bone height and lingual alveolar width and positive correlationship with labial alveolar base bone width.
