With the trend of shortening the treatment time and reducing patient discomfort/inconveniences immediate loading of implants has emerged as an alternative approach for replacing missing natural teeth. The aim of this study is to evaluate and compare the effectiveness of immediate implant loading protocol over conventional implant loading protocol in partially edentulous mandible.
Twenty patients were selected from out patients department who needed the replacement of one of the missing mandibular first molar. They were divided into two groups. In Group A patients implants were loaded with immediate implant loading protocol, whereas in Group B they were loaded with conventional loading protocol. Periimplant bone loss and soft tissue health were measured and compared using OPG and IOPA radiographs 06 and 12 months after implant placement.
One implant failed in immediate loading group (Group A), whereas all implants survived in conventional loading group (Group B). The average periimplant bone loss after 6 months and 1 year for Group A were 0.69 mm and 1.09 mm respectively, whereas it was 0.74 mm and 1.13 mm respectively for Group B. The difference in the bone loss between Group A and B was not statistically significant.
Immediate implant loading protocol has a highly acceptable clinical success rate in partially edentulous lower jaw although implant survival rate is slightly inferior to conventional loading protocol.
随着缩短治疗时间和减少患者不适/不便的趋势,种植体即刻负重已成为替代缺失天然牙的一种方法。本研究的目的是评估和比较即刻种植负重方案与传统种植负重方案在部分牙列缺失下颌骨中的有效性。
从门诊患者中选取20例需要替换下颌第一磨牙缺失的患者。将他们分为两组。A组患者采用即刻种植负重方案进行种植体植入,而B组采用传统负重方案。在种植体植入后6个月和12个月,使用口腔全景片(OPG)和牙片(IOPA)测量并比较种植体周围骨丢失和软组织健康情况。
即刻负重组(A组)有1枚种植体失败,而传统负重组(B组)所有种植体均存活。A组6个月和1年后种植体周围平均骨丢失分别为0.69mm和1.09mm,而B组分别为0.74mm和1.13mm。A组和B组之间的骨丢失差异无统计学意义。
即刻种植负重方案在部分牙列缺失的下颌骨中具有高度可接受的临床成功率,尽管种植体存活率略低于传统负重方案。
