This study aims to investigate the clinical outcome following treatment of peri-implantitis lesions. Five subjects with 7 implants were treated with surgical approach. Four subjects with 6 implants were initially treated with non-surgical approach or hygiene control. However, inflammation was not resolved and more bone loss was found. Therefore, surgical treatment was performed. After surgical exposure of the defect, granulation tissue was removed and implant surface was treated using tetracycline and chlorhexidine. Then, the flaps were sutured. The wound healing was performed in a non-submerged mode. The present finding demonstrates stable results without progression of bone loss. In one subject, deep V shaped bone defect was filled with bone substitute (ICB, CanCellous Bone, Rockey Mountain Tissue Bank, USA), and resorbable membrane (Lyoplant$^{(R)}$, B.Braun Aesculap AG, Germany) was placed over the grafted defect and healing abutment was connected. However, the inflammation was not resolved and more bone loss was found. At one month after regenerative surgery, the implant was removed.

This study was aimed to suggest to better treatment method of jaw cyst that the maximum diameter was wider than 3cm, using different treatment and clinical and radiographic result. We divided the 60 patients into three groups, group A(20 patients) were treated with cyst enucleation and Decalcified Freeze-Dried Allogeneic Bone(DFDB) graft, group B(20 patients) were treated with cyst enucleation and autogenous bone graft, group C(20 patients) were treated with only cyst enucleation. Each group was evaluated with panramic radiograph and clinical sign & symptom at pre-op and post-op(immediate, 6, 12, 24, 36 month). Bone density was evaluated with disital densitometer. The result was as follows : 1. Post-Op infection was higher in group C(4 pts.) than in group A(1 pt.) and B(1 pt.) 2. Post-Op gingival recession was higher in group C(3 Pts.) than in group A(1 pt.) and B(1 pt.) 3. Anatomic distortion was higher in group C(3 Pt.) than in group A(1 Pt.), and B(1 pt.) 4. reoperation was done in two patients who were in group C 5. There were donor site morbidity in two patients 6. there was no significant difference between group A and B in their bony density in their follow up period(p>0.05). 7. There were significant differences between group A, B and group C in their bony density until post-op 24 months but a little differences at post-op 36 months(P<0.01)

For the successful guided bone regeneration(GBR) of maxillary bony defect, proper soft tissue coverage is one of the most important things. Soft tissue dehiscence can be most common reason of osseous reconstruction failure. If a vascular supply to the graft should not develop from the host tissue, then the graft may also fail. Both of these prerequisites can be aided by judicious use of the buccal fat pad(BFP). Many methods for adequate soft tissue coverage have been proposed and the use of the BFP is one of them. BFP is useful in posterior maxillary area, can cover larger area and have higher blood flow than other methods. so the use of the BFP may offer protection and early blood supply to maxillary bone graft. This report describes the history, anatomy, blood flow, and clinical usefulness with two clinical cases.

Over the past decades, conventional complete dentures were used for various patients although they have incomplete function. Overdenture using dental implants could help the improvement of denture function. In this case, a fully edentulous patient was treated with a conventional complete denture on the maxilla and implant retained overdenture retained by 2 freestanding implants placed in the anterior region of the mandible, following recommendations from the 2002 McGill. Locator attachments were used for retention of the mandibular overdenture. Patient was satisfied with the final maxillary full denture and mandibular implant retained overdenture in esthetic and functional aspect.

Immediate implant placement is one of the treatment options in postextraction sites in anterior region. This article describes the high esthetic value of a single-tooth implant immediately placed in the anterior maxilla using a flapless approach and modifying a provisional restoration. The case reported illustrates the practical procedure involved in developing natural esthetics with modifying a provisional restoration. The technique provides an accurate impression of the soft tissue through the intraoral use of provisional restoration. The final restoration uses a custom-made titanium abutment and porcelain fused gold crown. The technique is relatively simple and provides excellent results from an esthetic point of view, which is demonstrated by the results of pink esthetic scores and white esthetic scores after 1 year.

The purpose of this study is to reveal the factors leading to the problem of unilateral condylar fractures and suggest a treatment guideline of treatment for good prognosis in surgical treatment. The factors can be age, sex, fracture site, degree of displacement, posterior occlusion loss, post-operative alteration of condylar head position, post-operative condylar head resorption, and maxillomandibular fixation period. One hundred and eleven patients with unilateral condylar fractures, who were treated by surgical method from 1990 Feb. to 2000 Feb., were studied. Minimum follow-up period was 6 months. The results were as follows ; 1. In the age group of 41-60, females had significantly higher complication rate than males, therefore we must be careful about treatment of female in this age group 2. In level I fractures of the mandibular condyle, because there were abundant complications when the patients were treated with fragment removal, conservative treatment is recommended over the surgical approach. 3. There were no differences in the complication rate, in the level Ⅱ, Ⅲ fractures. but were severe complications in the cases of patients treated by Dr.Nam's method or fragment removal. Therefore, open reduction and internal fixation is recommended over Dr.Nam's method or fragment removal. 4. In level Ⅳ fractures, open reduction and internal fixation is recommended 5. Although there was a higher complication rate depending on the degree of deviation, there was no correlation between the degree of deviation and development of complications in each level of fracture 6. Because the complication rate was higher in cases of condylar resorption, vertical dimension loss, and alteration of condylar head position, we must make an effort to prevent such complications during treatment

Prediction of the soft tissue changes following hard tissue movement is very important from the esthetic view point for patients who have orthognathic surgery. There are many cephalometric analysis of facial bone and soft tissue on the lower lip and chin region but few soft tissue analysis on the midface after mandibular setback surgery. This study was performed to obtain whether the mandibular posterior movement has influence on the midface and the predictable ratio of post-operative measurement values of the soft tissue changes following mandibular setback surgery. Fifteen patients (8 males and 7 females) who had undergone mandibular setback surgery were selected and analyzed the soft tissue movement on the upper lip and the cheek region. Post-operative changes of the soft tissue measurements after mandibular surgery were examined on pre- and post-operative cephalo-metrics and the ratio of changes were analyzed after drawing the reference line on the face with the barium sulfate solution. The reference lines were perpendicular to the intercanthal line from infraorbital foramen and lateral canthus. The results obtained were as follows : 1.There were tendancy of anterior movement of soft tissue adjacent the nose after mandibular surgery 2.There were incerased tendancy of the amount of anterior movement from the nasal crease to the cheek region. 3.The amount of anterior movement of the soft tissue was larger below the palatal plane compared with above the palatal plane in the cheek region. 4.The upper lip length was increased and moved posterior direction after mandibular setback surgery 5.The lower lip was moved posterior direction by posterior movement of the mandibular structure 6.Soft tissue of the midface around the nose moved anterior direction after mandibular setback surgery but there was no correlation between the amount of mandibular setback and the amount of the soft tissue changes

After performing mandibular setback surgery, we found some changes in patterns and organs of speech. This investigation was undertaken to investigate the aspect and degree of speech patterns according to the amount of surgical setback in mandibular prognathic patients. Thirteen patients with skeletal Class Ⅲ malocclusion were studied preoperative and postoperative over 6 months. They had undergone the mandible setback operation via bilateral sagittal split ramus osteotomy(BSSRO). We split the patients into two groups. Group 1 included patients whose degree of mandibular setback was 6mm or less, and Group 2 above 6mm. Control group was two adults wish normal speech patterns. A phonetician performed narrow phonetic transcriptions of tape-recorded words and sen- tences produced by each of the patients and the acoustic characteristics of the plosives, fricatives, and flaps were analyzed with a phonetic computer program (Computerized Speech Lab(CSL) Model 4300B(USA) ). The results are as fallows : 1. Genera1ly, Patients showed longer closure duration of plosives, shorter VOT(voice onset time) and higher ratio of closure duration against VOT 2. Patients showed more frequent diffuse distribution than the control group in frication noise energy of fricatives. 3. In fricatives, frequency of compact from were higher in group 1 than in group 2. 4. Generally, a short duraction of closure for /ㄹ/ was not realized in the patient's flaps. Instead, it was realized as fricatives, sonorant with a vowel-like formant structure, or trill type consonant. 5. Abnormality of the patient's articulation was reduced, but adaptation of their articulation after surgery was not perfect and the degree of adaptation was different according to the degree of surgical setback.

This study was aimed to furnish the data of facial bone fracture which was related regional and social environment and to aid diagnosis and treatment of the fracture. This is the retrospective and clinicostatical study on 626 patients with facial bone fracture. The patients were treated in the Dept. of Oral and Maxillofacial Surgery of Wonkwang University Hospital from Jan. 1, 1993 to Dec. 31, 1997. The result were as follows : The facial bone fractures occured most frequently in the twenties(32.3%) and male were predominent(77.4%) than female. The most frequent etiologic factor of facial bone fracture was fall down(42.8%) and midface fracture was traffic accident(63.4%). The most common site of fracture was symphysis(51.1%) and angle(29.7%), condyle(27.5%), ZMC(13.4%) were next in order of frequency. Of the 626 patients, 590 patients(89.5%) were treated with open reduction and only 36 patients(10.5%) were treated with closed reduction. In the blow, the ratio of angle fracture(50%) is especially high(the overall ratio 29.7%) and in the Out car TA, the ratio of ZMC fracture(34.6%) is especially high(the overall ratio 13.4%). In the Fall-down, the ratio of symphysis(58.4%) and condyle fracture(33.6%) is especially high(the overall ratio 51.1%, 27.5%). Postoperatives complication were found in 35(5.6%) of 626 patients, in which mouth opening limitation(3%) was the most common. Above results suggest that early diagnosis and treatment of fracture site, systemic condition and associated injuries are nessary, and cooperative treatment with medical department should be performed.
