The purpose of this study is to evaluate the effect of HTR?? (hard tissue replacement, Bioplant Inc, U.S.A) polymer on short-term healing as a grafting material for alveolar ridge augmentation. A 48-year-old female presented insufficient bone height and width for the placement of implants. HTR?? polymer was used for ridge augmentation. Bone biopsy was harvested 8 months after the ridge augmentation procedure. HTR?? polymer displayed rapid bone regeneration and mature lamellar and trabecular bone redevelopment. Clinical and histologic observation from the treatment of the patient presented suggest that HTR?? polymer seems to be a appropriate material for alveolar ridge augmentation.

Soft tissue defects in oral & maxillofacial region caused by tumor resection, trauma, congenital deformities have been treated in autogenous soft tissue flap, allogenic material, free dermal graft, fascia graft. Of these methods, autogenous dermis graft had initially been applied in hernia treatment at the beginning of nineteenth century and have been applied in soft tissue augmentation coverage of vital structure, dead space removal and reconstruction of fascia. A fat graft is used in reconstruction of orbit at the enucleation, restoration of facial contours, etc. In this case, patient with chin soft tissue defect in traffic accident was treated in autogenous dermis-fat graft from patient's abdominal and gluteal region. Chin defect was recons ructed favorably. There was no severe atrophy of grafted area 12 months postoperatively. We will report the result that is favorable esthetically with literature review.

Distraction osteogenesis (DO) is a surgical process for reconstruction of combined deficiencies in bone and soft tissue. It involves gradual, controlled displacement of surgically created fractures which results in simultaneous expansion of soft tissue and bone volume. Due to the late introduction of healing by DO in the field of odontology, alveolar DO is increased. The process of alveolar DO involves osteotomy in the area of deficiency, fixation of a healthy segment of bone adjacent the deficient site, transport, and maintenance of newly formed bone. After a 7- or 10-day latency period for soft tissue healing, distraction is performed at the rate of 0.5㎜ twice a day fully to 7㎜. The distractor is then maintained for consolidation after distraction for 10- to 12 weeks. After consolidation, the distractor is removed. Improvement of vertical bone regeneration was achieved in all cases. The resultant distraction zone is filled with natural bone, consistent with the distraction osteogenesis concept. This results in mature cortical bone at the crest for enhanced implant stability and prosthodontic treatment.

Superior orbital fissure syndrome is characterized by ophthalmoplegia, ptosis of the eye, reflex dilation of the pupil, and anesthesia of the upper eyelid and forehead. This syndrome may be the result of craniofacial fractures as well as neoplasms of the retrobulbar space, hematomas in the orbital muscle cone and retrobulbar space, and hematoma and infection of the cavernous sinus. A case of superior orbital fissure syndrome is described.

Rough rice(Chucheong) which had been harvested at the experiment station, Chung Buk National University on October 26, 1992, was used in this experiment. The rough rice was divided into two parts. A part of the rough rice was parbolied(B series) and another part was untreated(A series). Brown and polished rice was obtained from untreated and parboiled rice. Six different types of the rice stored at room temperature for about 10 months. During the storge time, moisture and crude lipid contents, free fatty acid values, peroxide values, TBA values and fatty acid compositions were investigated. The result was as follows. 1. The moisture contents of all the samples decreased remarkably during the storage periods. Polished rice showed the greatest decrease. The decreasing rate was pronounced between 3-7 mouth. 2. The crude lipid contents of the polished and brown rice increased during the storage periods. As the moisture contents decrease, the crude lipid contents was increased proportionally. The crude lipid contents of rough rice were rarely changed. 3. The free fatty acid values of all the samples increased during the storage periods. The increasing rate was pronounced between 5-9month. The free fatty acid values of polished rice was greater than those of brown and rough rice. 4. Peroxide values of all the samples increased during the storage periods. Especially, the increase in the peroxide values remarked between 5-9month. The peroxide values of untreated rice were greater than those of parboiled rice. 5. TBA values of all the samples increased during the storage periods. Its increase pattern were similar to the peroxide values. 6. Major fatty acids of the samples were oleic acid, and linoleic acrid, palmitic acid. A little of stearic acid, myristic acid, linolenic acid, and arachidic acid was found. The changes in fatty acid composition of the each samples were rarely noted during the storage periods.

The purpose of this study was to investigate the epidemiology of midface fratures. We observed clinically 71 patients with midface fracture who visited the Department of oral and maxillofacial-surgery, Chosun University, Dental Hospital, from 1991 to 1994. The results obtained were as follows. 1. There was the highest age incidence in the third decade(29.6%). 2. There was the highest incidence in the summer(36.6%). 3. The most etiologic factor of midface fracture was traffic accidents(43.6%) and next factor was fall down(38.0%). 4. The highest incidence fracture was zygomatic arch(38.7%) and next fracture was ZMC fracture(31.5%). 5. Most midface fracture was treated within 2 weeks(86.7%). 6. Midface fractures was most frequently combined with mandibular fracture(15.5%), head injuries(14.1%),orthhopedic injuries(8.5),thorax & abdomen(5.6%). 7. The highest complication was the nerve injury(8명), and next complications were infection(3명), epiphora(3명) etc.

The purpose of this study was to investigate the mean cranial bone thickness at various points of the bone and to serve as a clinical guide for choosing a bone graft. Twelve bones were obtained from 6 Korean adult skulls for this study. The mean bone thickness at each point of the 17 points of the bone and at the corresponding points of the opposite bone was obtained in all skulls studied. The thinnest part of the parietal bone was 5.92mm. The thickest part of the parietal bone was 7.58mm. The mean bone thickness at each point of measurements on two opposite bones was compared using the paired Student's t-test. The mean thickness did not differ significantly. The thickness in the same bone varied widely depending on the points of measurement.

Odontogenic fibromyxomas are extremely rare benign odontogenic tumors that probably arise from interstitial portion of jaw bone. The plain X-ray showed osteolytic destructive lesions in the molar root area. CT scans demonstrated osteolytic expansile lesions with mild enhancement of the solid portion of the mass. Histologically, the tumor is composed of fibrous tissue and myxoid tissues. In this paper a case of odontogenic fibromyxoma of the maxilla and a review of the literature is presented.

Medpor 매식후 치유과정에서 Methylprednisolone 이 미치는 영향

김수관,정성수 대한악안면성형재건외과학회 2000 Maxillofacial Plastic Reconstructive Surgery Vol.22 No.2

The purpose of this study is to evaluate the difference in healing of Medpor□ implants of two different thickness (1.5mm and 4.5mm) and the effects of methylprednisolone on the healing process. Light micro-scopic and scanning electron microscopic examinations, and hardness measurement were made in 100 rats 2, 4, or 8 weeks postoperatively. The 1.5mm thin implants were taken better than the 4.5mm thick implants. The inflammatory responses were reduced after application of methylprednisolone with arrangement and amount of bone matrix deposited being more irregular and reduced in bulk than in the control group. To hasten postoperative healing after Medpor□ implantation, the thinner material should be used and steroid injection should be avoided. Key Words : Medpor□, methylprednisolone

As the laser becomes more widely available in recent years, the oral and maxillofacial surgeon will have greater opportunity to use it for the treatment of soft tissue and hard tissue pathologies of the mouth. However, little information has been published on the bone. Dental lasers serve as an adjunct to regular treatments and enhancing outcomes in still others. The laser replaces conventional therapies with equal or improved results. Lasers offer new treatment options that heretofore were not available. Laser dentistry is capable of significantly minimizing discomfort, enhancing recovery times, and improving the overall efficiency of the dental office. We describe the basic researches and the developimg laser devices.
