Generalized periodontitis treated with periodontal,orthodontic,and prosthodontic therapy:A case report

BACKGROUND Generalized periodontitis is a severe periodontal disease characterized by rapid periodontal destruction in healthy persons.This case report describes the treatment of a severe crowding,large overjet,and occlusal collapse due to the loss of anterior guidance with generalized periodontitis.CASE SUMMARY A 35-year-old female patient with a chief complaint of crowding and maxillary protrusion was diagnosed with generalized periodontitis by clinical and radiographic examinations.To improve crowding and overjet,orthodontic treatment was performed after basic periodontal therapy.Severely damaged upper right lateral incisor and left canine were extracted,and lower right first premolar and left second premolar were also removed to treat severe crowding.After orthodontic treatment,periodontal flap surgery for upper left molars and guided tissue regeneration for the lower left second molar was performed.Then,a dental implant was inserted in the upper left canine legion.The esthetics of the maxillary anterior tooth was improved by prosthetic restorations.The treatment result showed a well-improved occlusion with proper anterior guidance and healthy periodontal tissue after a retention period of 10 years.CONCLUSION Periodontal,orthodontic,and prosthodontic treatments are extremely useful to improve function and stable periodontal tissue for generalized periodontitis.

错[牙合]畸形伴牙列缺损患者行口腔正畸联合修复治疗的效果

目的分析错[牙合]畸形伴牙列缺损行口腔正畸联合修复治疗的效果。方法选取本院收治的80例错[牙合]畸形伴牙列缺损患者为研究对象,随机分为对照组和研究组。对照组患者给予口腔正畸治疗,研究组患者给予口腔正畸联合修复治疗,比较2组患者治疗效果、牙齿功能评分以及治疗前后生活质量。结果研究组患者治疗总有效率为97.50%,对照组患者治疗总有效率为80.00%,差异有统计学意义(P<0.05)。治疗干预后,研究组患者咀嚼功能、语言功能、舒适度、美观度等指标评分均显著优于对照组(P<0.05)。治疗干预后,研究组患者生活质量评分为(56.23±1.62)分,对照组为(79.66±2.05)分,2组比较差异有统计学意义(P<0.05)。治疗干预后,研究组患者在牙齿固定评分、软垢指数、牙菌斑附着指数等指标评分显著优于对照组(P<0.05)。结论与单一口腔正畸治疗比较,口腔正畸联合修复治疗有助于改善咀嚼功能和言语功能,提升牙齿美观度,且安全性较高,不良反应较少。

牙周炎综合治疗的临床疗效观察

目的:回顾性分析牙周炎综合治疗的临床疗效。方法:实验组为获得较完整牙周炎综合治疗的患者61例,对照组选择长期仅作基础治疗和药物治疗的牙周炎患者40例,回顾性评价两组临床指标的变化。结果:实验组平均失牙数低于对照组(P<0.05)。牙周探诊深度,治疗前两组基线无统计学差异。实验组治疗后较基线改善(P<0.05),对照组较基线恶化(P<0.05)。结论:10年追踪观察表明,只有通过牙周炎综合治疗方案才能最大限度保证取得短期或长期的牙周治疗效果,单一牙周治疗对长期有效稳定控制菌斑和消除牙周袋疗效不肯定甚至无效。

正畸-临时修复联合治疗对上颌切牙位置的保持效果

目的:探讨正畸术后即行临时修复治疗对患者上颌切牙位置的保持效果。方法:将于北京大学口腔医院第五门诊部就诊行正畸-修复联合治疗的患者20例,随机分成两组。实验组在正畸治疗完成后即行临时修复治疗,1周内完成永久修复,保持3个月;对照组在正畸治疗完成后即保持3个月,然后行上前牙永久修复治疗。使用数字模型记录实验组与对照组患者分别在正畸-永久修复治疗完成后(T_(X)1)、保持3个月后(T_(X)2)、正畸治疗完成后(T_(C)1)、保持3个月(T_(C)2)后患牙位置的变化。测量患牙在空间移动中牙轴角度变化、冠切线角度变化、近远中向距离变化、垂直向距离变化等指标,分析患牙移动与保持的效果。结果:两组患者T1与T2时间点相比,患牙位置均有变化。对照组牙轴角度变化、冠切线角度变化、近远中向移动量和垂直向移动量均大于实验组;两组间牙轴角度变化、近远中和垂直向移动量均存在统计学差异(P<0.05)。结论:正畸-临时修复治疗较常规正畸后保持3个月再行修复治疗相比,可有效保持上颌切牙的位置。
