摘要:

文题释义:

盾构术:2010Hürzeler教授首次提出该技术,即刻种植前保留部分唇侧牙根结构,从而保存原天然牙与唇侧骨之间的牙周膜,减少唇侧束状骨的吸收。但较早的术式中种植体与牙片接触仅0.5 mm的跳跃间隙,增加了手术难度且存在一定的失败率,之后学者们对该术式进行了不同方法的改良。此次研究的改良是将跳跃间隙扩大到2 mm并在间隙中植入异种骨替代品。

唇侧束状骨:上颌前牙区唇侧骨壁较薄,主要由束状骨组成。唇侧束状骨是由牙周韧带发育而来的一层骨质,牙齿拔出后会很快吸收,造成牙龈退缩,唇侧丰满度降低,给美学区种植带来巨大风险。

背景:常规盾构术可减少上前牙即刻种植即刻修复后唇侧束状骨的吸收,但该技术对术者要求很高,种植体植入时容易造成唇侧余留牙片的松动,导致手术失败。

目的:评价上颌美学区改良盾构术与常规不翻瓣即刻种植即刻修复的临床效果。

方法:纳入20169月至20178月滨州医学院附属医院收治的60例口腔修复科患者,其中男33例,女27例,年龄20-81岁,包括中切牙38例、侧切牙22例,随机分2组:试验组30例接受改良盾构术即刻种植即刻修复,对照组30例接受常规不翻瓣即刻种植即刻修复。1年后复诊,记录种植体存留率,测量两组红色美学指数评分,锥形束CT检测种植体颈部及其根方24 mm的唇侧骨板厚度,调查患者对种植义齿的满意度。研究经过滨州医学院附属医院医学伦理委员会的审核批准(医院伦理批件号:2019-LW-025)

结果与结论:①两组种植体存留率均为100%;②试验组术后1年的红色美学指数评分高于术前、对照组(P < 0.05),对照组术后1年的红色美学指数评分低于术前(P < 0.05);③试验组术后1年的植体颈部及其根方24 mm唇侧骨厚度吸收均小于对照组(P < 0.05);④试验组患者满意度高于对照组(P < 0.05);⑤结果表明,改良盾构术即刻种植即刻修复有利于唇侧骨厚度的维持,能获得更好的美学效果。

Abstract:

BACKGROUND: The conventional shield technique can reduce the absorption of labial fasciculate bone after immediate implantation of anterior teeth, but it is highly demanded by the operator. When implants are implanted, it is easy to loosen the remaining teeth on the labial side, resulting in failure of the operation.

OBJECTIVE: To evaluate the clinical effects of a modified socket shield technique for immediate implant and immediate restoration and flapless immediate implant and immediate restoration in maxillary aesthetic area.

METHODS: Sixty patients were randomly chosen with failing tooth from September 2016 to August 2017 in Department of Stomatology in Affiliated Hospital of Binzhou Medical College. The samples included 33 males and 27 females, aged from 20 to 81 years. There were 38 cases of central incisor and 22 cases of lateral incisor. The patients were randomly divided into two groups. The 30 patients in the experimental group received a modified socket shield technique for immediate implant and immediate restoration. The 30 patients in the control group received conventional flapless immediate implant and immediate restoration. During return visit after 1 year, the retention rate of the implant and pink esthetic score were recorded; the buccal bone thicknesses of the implant neck and roots 2, 4 mm were observed by cone beam computed tomography; and the patient satisfaction was analyzed. The study was approved by the Medical Ethics Committee of the Affiliated Hospital of Binzhou Medical College (Hospital Ethics Approval Number: 2019-LW-025).

RESULTS AND CONCLUSION: (1) The survival rate of both groups was 100%. (2) One year after operation, the pink esthetic score of the experimental group was higher than the preoperative score and that in the control group (P < 0.05). The pink esthetic score of the control group was lower 1 year after surgery than preoperative score (P < 0.05). (3) One year after operation, the buccal bone thickness loss of the implant neck and roots 2, 4 mm in the experimental group was lower than that in the control group (P < 0.05). (4) The satisfaction rate of the experimental group was higher than that in the control group (P < 0.05). (5) The results showed that the modified socket shield technique used for immediate implant and immediate restoration can maintain the buccal bone thickness and improve the aesthetic effect.
