The effects of modified adhesion retention on the surrounding tissues of dental implant / 实用口腔医学杂志

ABSTRACT

Objective:To investigate effects of the modified adhesion retention on the surrounding tissues of dental implant.Methods:182 patients with tooth defects were randomly divided into 2 groups,The patients in control group (n =89) received the traditional retention,in the test group(n =93) received modified adhesion retention.The bone loss at the near and far edges of the implant,alveolar bone height and thickness,the pictorial view of pink esthetic score variables(PES),the modified plaque index(mPLI),the modified sulcus bleeding index (mSBI) and the satisfaction were recorded and compared 1 year after treatment.Results:Compared with control group,the test group showed less bone loss(P＜0.05),more alveolar bone height and thickness(P＜0.05).The satisfaction of the comfort,chewing and language function,retention,esthetics,PES,mPLI and mSBI improved to varying degrees(P＜0.05).Conclusion:The modified adhesion retention is more effective than the traditional retention in stabilizing the bone support of implant and reduce bacterial infection.
