PURPOSE: The purpose of this study was to analyze the current literatures and to assess outcomes of implant treatment in patients with generalized aggressive periodontitis. MATERIALS AND METHODS: Studies considered for inclusion were searched in Pub-Med. The literature search for studies published in English between 2000 and 2012 was performed. Our findings included literature assessing implant treatment in patients with a history of generalized aggressive periodontitis (GAP). All studies were screened according to inclusion criteria. The outcome measures were survival rate of superstructures, marginal bone loss around implant and survival rate of implants. All studies were divided into two follow-up period: short term study ( or = 5 years). RESULTS: Seven prospective studies were selected, including four short-term and three long-term studies. The survival rates of the superstructures were generally high in patients with GAP, i.e. 95.9 - 100%. Marginal bone loss around implant in patients with GAP as compared with implants in patients with chronic periodontitis or periodontally healthy patients was not significantly greater in short term studies but was significantly greater in long term studies. In short term studies, the survival rates of implants were between 97.4% and 100% in patients with GAP-associated tooth loss, except one study. The survival rates of implants were between 83.3% and 96% in patients with GAP in long term studies. CONCLUSION: Implant treatment in patients with GAP is not contraindicated provided that adequate infection control and an individualized maintenance program are assured.

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.

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.

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 625 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.
