Background

Bonding of orthodontic brackets to teeth is important to enable effective and efficient treatment with fixed appliances. The problem is bracket failure during treatment which increases operator chairside time and lengthens treatment time. A prolonged treatment is likely to increase the oral health risks of orthodontic treatment with fixed appliances one of which is irreversible enamel decalcification.

Objectives

To evaluate the effectiveness of different orthodontic adhesives for bonding.

Search methods

Electronic databases: the Cochrane Oral Health Group's Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE.
Date of most recent searches: August 2002 (CENTRAL) (The Cochrane Library 2002, Issue 2).

Selection criteria

Trials were selected if they met the following criteria: randomised controlled trials (RCTs) and controlled clinical trials (CCTs) comparing two different adhesive groups. Participants were patients with fixed orthodontic appliances. The interventions were adhesives that bonded stainless steel brackets to all teeth except the molars. The primary outcome was debond or bracket failure.

Data collection and analysis

Data were recorded on decalcification as a secondary outcome, if present. Information regarding methods, participants, interventions, outcome measures and results were extracted in duplicate by pairs of review authors (Nicky Mandall (NM) and Rye Mattick (CRM); Declan Millett (DTM) and Joy Hickman (JH2)). Since the data were not presented in a form that was amenable to meta-analysis, the results of the review are presented in narrative form only.

Main results

Three trials satisfied the inclusion criteria. A chemical cured composite was compared with a light cured composite (one trial), a conventional glass ionomer cement (one trial) and a polyacid-modified resin composite (compomer) (one trial). The quality of the trial reports was generally poor.

Authors' conclusions

It is difficult to draw any conclusions from this review, however, suggestions are made for methods of improving future research involving orthodontic adhesives.

Adhesives for fixed orthodontic brackets

It is useful for a clinician to know the best adhesive for fixing orthodontic brackets, so they do not fail during treatment.
Bracket failure increases the time spent in surgery for repairs and the overall treatment time. At present orthodontics can choose between four groups of adhesives which may be set with a chemical reaction or curing light. Some adhesives may prevent early decay around brackets because they contain fluoride. There is only weak unreliable evidence that one adhesive may possibly have more failures associated with it and another adhesive may be more protective against early decay.

背景

固定式矯正托架之黏著劑

矯正托架與牙齒之間的黏著力對於固定式矯正治療的效率是很重要的。若在治療過程中,矯正器的脫落,非但會增加醫師門診的時間,而且也會加長治療療程的時間。過長的治療時間會危害口腔健康,其中一項危險是琺瑯質的脫鈣。

目標

評估不同矯正用的黏著劑對於黏著的效率。

搜尋策略

電子資料庫:主要由Cochrane Oral Health Group's Trials Register、 the Cochrane Central Register of Controlled Trials (CENTRAL)、 MEDLINE及EMBASE.找最近期的資料: 2002年8月 (CENTRAL) (The Cochrane Library Issue 2, 2002)

選擇標準

依據以下的納入標準搜尋:以隨機受控性試驗(randomised controlled trials)、臨床受控性試驗(controlled clinical trials)來比較兩種黏著劑者,參與的病人必須佩戴固定式矯正裝置,黏著劑用來固定除了大臼齒區外的不鏽鋼拖架,而主要結果為矯正器脫落或失敗。

資料收集與分析

錄中若有出現脫鈣(decalcification),視為第二個結果。利用兩位回顧者來精選關於實驗方法、參與者、黏著方法、效果與結果的部份。由於資料呈現無法進行統合分析,所以結果以敘述方式來表示。

主要結論

其中有三篇滿足納入標準。分別為化學聚合樹脂與光照聚合樹脂、傳統玻璃離子樹脂及改良式多酸樹脂(compomer)的比較,但是試驗指出這些品質都很差。

作者結論

從這些文獻回顧中很難得到一個結論,這表示說未來需要發展出改善研究方式的方法。

總結

對於一個臨床醫師,為了避免治療中的失敗,知道固定式矯正裝置最佳的黏著性是很有用的,拖架鬆脫除了需費時修復,還會讓整個治療期間增長。現在的矯正醫師,包括了化學聚合及光聚合等等,可以有4種黏著劑的選擇。有些黏著劑,其成份中含氟,可以早期預防托架周圍的蛀牙,與較高的失敗率可能有關,但目前證據仍較薄弱。
