中文摘要 | 本研究的目的在探討植入骨內錨定的外科併發症與不同形式植入物、不同植入位置及骨內錨定失敗的相關性。從90年9月至94年8月成大醫院齒顎矯正科資料中,將接受骨內錨定的25位患者以回溯性方式分析資料。其中4位男性,21位女性,平均年齡23歲;共植入骨內錨定77個,包括迷你骨板47片、迷你骨釘28支,微骨釘2支。其中,骨內錨定放置於上顎後方頰側37個及腭側14個,下顎後方頰側23個,上顎前方頰側2個及腭側1個。錨定用於前牙後拉30個,牙齒下壓26個,牙齒前拉11個,同時牙齒後拉及下壓6個,後牙扶正2個,後牙後退1個,牙齒突出1個。所有病例於術後追蹤12個月,結果顯示有16個骨內錨定具外科併發症,包括骨釘6個及骨板3個發炎、骨板6個感染及骨板1個感覺異常;上、下顎各發生8個,除了1個外,全部發生在頰側。骨內錨定一年成功率為88.3%,其中6個在矯正前鬆脫移除,另3個骨板/骨釘在矯正中鬆脫移除,9個全部發生在上顎,且其中4個有感染的併發症。我們的結論是:骨板比骨釘容易發生外科併發症,而併發症與植入位置沒有關係,但是骨板較骨釘容易失敗,主要發生部位在上顎頰側,而且感染可能是造成失敗的主要原因之一。 |
英文摘要 | Purpose: The aim of this study is to assess the surgical complications associated with type, position or failure of skeletal anchorage for orthodontic treatment. Materials and Methods: A total of 77 skeletal anchors (47 mini-plates, 28 mini-screws and 2 microscrews) in 25 patients (4 males and 21 females) were examined in the study. The average age of patients is 23 years. The skeletal anchors were placed in different locations. Among them, 51 were in the posterior maxilla (37 buccal & 14 palatal sides), 23 in posterior mandible (buccal side), and 3 in the anterior maxilla (2 buccal & 1 palatal sides). The skeletal anchors were used for different purposes including 30 for retraction, 26 for intrusion, 11 for protraction, 6 for retraction & intrusion, 2 for uprighting, 1 for distalization and 1 for extrusion. The complications were examined for a period of 12 months after surgical installation. Results: Surgical complications were observed in 16 skeletal anchors (20.8%). They included inflammation in 6 screws & 3 plates, infection in 6 plates, and paresthesia in one plate. All occurred in the buccal sides except one in palatal side. Among them, eight occurred in the maxilla, eight in the mandible. One year success rate of skeletal anchorages was 88.3%. Six plates were loosening before orthodontic use, and three anchors were loosening and removed during orthodontic use within one year. All occurred in the maxilla. Conclusions: The study suggested that surgical complications of skeletal anchorage were more commonly observed in miniplates than miniscrews, and there were no difference between the maxilla and the mandible. Failure often occurred in the buccal side of the maxilla and infection was one important factor causing failure of skeletal anchorage. |
