ABSTRACT
Recent development of dental implantology has taken an interest in the bone graft procedure. This is a review of literature, published from 1994 to November 1999. This study is provided by MEDLINE search. In this study, 718 patients received 829 graft with placing 2,677 endosseous implants. In mandible, nonvascularized or vascularized block bone grafts provided better results (success rate 95.2%) than particulate grafts(83.6%). But in maxilla, particulate grafts provided better results(93.7%, 86.2%) and more cases especially in sinus elevation. There were many cases using autogenous bone graft and revealed good results, but allogenic or alloplastic bone graft materials also were used by many surgeons.

This report was a 10year retrospective study on mandible fractures. The study was based on a series of 245 patients who had been treated for mandibular fractures as in-patient at Yongsan Hospital of Medical college of Chung-Ang University during the period of Jan. 1987 to Dec. 1996. The results obtained are as follows; 1. In respect of incidence, the number of fractures was increased to 1990 and then it was decreased. The ratio of Men to Women was 6 : 1. 2. The major etiologic factors were traffic accident(30.2%), fisticuffs(28.6%), falldown(25.3%), accident related to work(7.8%), and sports(6.9%). In recent years, the decreasement of fractures due to traffic accident and the increasement of fractures due to sports was impressive. 3. The age frequency was highst in the third decade(44.9%), and second(%), fourth(%), decade in orders. In the first decade, the cause of fractures was traffic accident and falldown only, and the fractures due to sports were concentrated on second and third decade. 4. The frequent location of mandibular fractures was symphysis(36.1%), left angle(16.4%), right condyle(10.4%), right angle(8.6%), left condyle(8.6%), left body(5.8%), left ramus(4.0%), ramus(3.8%). The number of average fracture site was 1.62 at each patient and the number of average fracture line was 1.91 at each patient. 5. The simple fracture was 43.7%, and the complex fracture was 56.3%, then the open fracture was 35.5%, and the closed fracture was 64.5%. 6. In respect of treatment, the frequency of open reduction was 74.3% and that of closed reduction was 25.7%, but in the condyle, closed reduction(68.0%) was the more frequently using method of treatment than open reduction(32.0%). 7. The patients were treated an average of 3.27 days after injury and the average hospitalization period was 10.07 days. 8. The mandibular 3rd molar was existing in 60.6% of angle fractures.

The purpose of the present placebo-controlled double-blind study was to investigate the preventive effect of 5mg dexamethasone on swelling, trismus, and pain after removal of impacted mandibular third molars with bone reduction. The participants were consisted of 20 healthy individuals(9 male, 11 female) with bilaterally symmetrical impacted mandibular third molars. Each patient served as his own control. Immediately after removal of impacted teeth, either 5mg dexamethasone or normal saline was injected intramuscularly. On the first day, 2nd day, and 7th day after operation, facial swelling, trismus, and pain were evaluated. On the first day, the difference in the volumetric change of facial swelling was 45% (p<0.05) as measured by Holland's nine pointers facebow. The trismus was reduced by 28% (p<0.01) in test froup. Pain assessed with Visualanaloguescale(VAS) was reduced by 33% (p<0.001) by dexamethasone. It can be concluded that sterokd treatment is recommended in third molar surgery when pronounced postoperative swelling, trismus, and pain are expected.
