文题释义:

两段式种植体:即种植体基台与固位体分为两段而不是一个整体的种植体。手术时,与骨组织结合的固位体和与牙龈组织结合的基台是前后分别进行2次完成,而在基台与固位体两段之间是通过种植体中心螺丝将其相连成为一个整体。首次植入先将固位体植入骨组织内,缝合伤口,待种植体固位体在完全无负载的休息状态下与骨组织产生骨结合后,再行二次植入,即切开牙龈组织,通过种植体中心螺丝连接基台,拆线后即可取模并完成最终修复体。优点是种植体骨结合好,不易感染,义齿的修复方式多样,其上部结构可多种选择,远期效果好,成功率高,缺点是需经两次种植才能完成。
口腔种植体:也称为牙种植体或者人工牙根。是通过外科手术的方式将其植入人体缺牙部位的上下颌骨内,待其手术伤口愈合后,在其上部安装修复假牙的装置。

 

背景:种植体-基台连接面已逐渐成为种植修复成功的一个关键因素,但多种不同基台链接方式对种植体周软组织的影响尚不清楚。
目的:比较3种不同的基台连接方式对于前牙美学区种植体颈部牙槽骨和软组织的影响。
方法:随机选择60例上颌美学区单牙种植修复患者,其中传统平台对接贝格种植体20例,平台转换奥齿泰TS型种植体20例,士卓曼穿龈式种植体20例。种植后3-6个月行二期手术,即刻拍摄X射线片,将测量所得种植体周围骨高度作为基准线,2周后取模,行永久冠修复。修复后12个月再次拍摄X射线片,测量种植体周围边缘高度和评价软组织的情况。
结果与结论:不同连接方式种植修复后种植体周围边缘骨吸收量与红色美学指数具有显著差异,平台转换种植体的骨吸收量明显少于传统基台连接组(P < 0.05),红色美学指数也高于传统基台连接组(P < 0.05)。结果说明,平台转换种植体在上颌美学区单牙种植修复相较于传统基台连接种植体能更有效的保留周围骨组织且美学效果较佳。

Abstract:

BACKGROUND: Implant-abutment connection has become a key factor in the success of implant restoration, but 
the effects of different implant-abutment connections on peri-implant tissues is unclear.
OBJECTIVE: To compare the effects of three different implant-abutment connections on the alveolar bone and peri-implant soft tissues at the maxillary esthetic zone.
METHODS: Sixty patients undergoing aesthetic restoration of single maxillary anterior tooth were enrolled randomly, including 20 cases of Bego Replace system, 20 of Osstem Replace system, and 20 cases of ITI Replace system. All the patients had a follow-up of 3 to 6 months after the surgery, and then received the two-stage surgery. Radiographic and clinical examinations were made at the same time. Peri-implant bone height measured was used as the reference line. The final crowns were made after 2 weeks, and the peri-implant bone resorption and pink esthetic scores were evaluated after 12 months shown through X-ray films.
RESULTS AND CONCLUSION: There were significant differences in peri-implant marginal bone loss and pink esthetic scores among different groups after implant restoration. The amount of marginal bone loss around implants using platform switching was significantly less than that using platform butt-joint (P < 0.0.5), and the pink esthetic scores of the former group was higher than the later one (P < 0.05). These findings indicate that aesthetic restoration of a single maxillary tooth implant using platform switching is able to preserve better marginal bone and acquire better aesthetic effects.
