为了评估组合缺陷的影响,骨破坏和分叉参与,在手术后从口袋消除方面的疾病消退,没有炎症,分叉改进和预测性能。
在诊断为牙周炎III至IV期的患者中,上颌磨牙的骨性(骨内(+)或(-))和分叉缺损(FI程度1或2),通过牙周手术和至少6个月的随访进行回顾性筛选。累积可预测性(CR,%),治疗失败和临床参数从基线的变化在术前访问到最新的维护护理,包括口袋深度(PD),分析了水平和垂直分叉受累(FI)。具有低可预测性的治疗失败被定义为在维持期间探查时残余PD>4mm且出血。
纳入33例合并缺损51例患者。统计学分析显示显著的总体PD减少和FI改善(p<0.001)。与带上缺损的FI程度2相比,结合有带内()缺损的FI程度2显示出更多的水平分叉改善(p=0.007)。然而,合并缺陷类型与CR(p=0.702)和PD减少(p=0.707)无关.在所有参数中,基线PD伴近端FI2度提示治疗失败。
不同类型的组合缺陷,较深的基线口袋和近端FI2度会影响上磨牙治疗结果的可预测性.然而,手术治疗和严格的维持护理相结合仍然可以产生高的可预测性和生存率。

To evaluate the impact of combined defects, bony destruction and furcation involvement, on disease resolution after surgery in terms of pocket elimination, absence of inflammation, furcation improvement and predictive performance.
Combined bony (intrabony (+) or (-)) and furcation defects (FI degree 1 or 2) at maxillary molars in patients diagnosed as periodontitis stage III to IV, being through periodontal surgery and at least 6 months follow-up were retrospectively screened. Cumulative predictability (CR, %), failure of treatment and the change of clinical parameters from baseline at pre-operative visit to the latest maintenance care, including pocket depth (PD), horizontal and vertical furcation involvement (FI) were analyzed. Failure of treatment with low predictability was defined as residual PD > 4 mm with bleeding on probing during maintenance period.
Thirty-three patients with fifty-one combined defects were included. Statistical analysis showed significant overall PD reduction and FI improvement (p < 0.001). Combined FI degree 2 with intrabony (+) defects revealed more horizontal furcation improvement compared with FI degree 2 with suprabony defect (p = 0.007). However, type of combined defects was not relevant to CR (p = 0.702) and PD reduction (p = 0.707). Among all parameters, baseline PD with proximal FI degree 2 was indicated to failure of treatment.
Different types of combined defects, deep baseline pocket and proximal FI degree 2 would compromise the predictability of treatment outcomes in upper molars. Nevertheless, the combination of surgical treatment and strict maintenance care could still yield high predictability and survival rate.
