摘要

目的:比较两种修复基牙直接种植体在修复初期的软组织和硬组织变化。材料与方法:采用改良截骨法将28颗即刻种植体置入磨牙/前磨牙槽内。种植体周围的间隙用脱蛋白牛骨矿物质进行移植。根据种植体的牙槽大小,将种植体与钛修复基台(传统组)或定制修复基台(CA组)相连接。术前、术后和6个月回顾时均行x线和口内检查。结果:两组间颊部(P = 0.717)和舌部(P = 0.087)垂直骨丢失具有可比性。CA组远端缺损不完全填充更明显(P = 0.000)。两组间颊骨厚度变化相似(种植平台P = 0.902)。两组均能较好地维持面部中部软组织水平。结论:在本研究的局限性内,对于即刻植入后牙槽骨的种植体,定制的愈合基台可以促进大牙槽骨的闭合。尽管更明显的不完全缺损填充,由聚醚醚酮和树脂组成的愈合基台在早期愈合期间不会增加种植体周围骨丢失或软组织衰退的风险。

Early Healing of Immediate Implants Connected With Two Types of Healing Abutments: A Prospective Cohort Study.

Purpose: To compare hard- and soft-tissue changes around immediate implants connected with 2 types of healing abutments during the early phases of healing.

Materials and methods: Twenty-eight immediate implants were placed into molar/premolar sockets through a modified osteotomy method. The gaps around implants were grafted with deproteinized bovine bone mineral. According to the size of the alveoli, the implants were connected with titanium healing abutments (traditional group) or customized healing abutments (CA group). Radiographic and intraoral examinations were performed before surgery, postoperatively, and at the 6-month recall.

Results: Buccal (P = 0.717) and lingual (P = 0.087) vertical bone loss was comparable between groups. More significant incomplete defect fill was found at the distal aspect of the CA group (P = 0.000). The buccal bone thickness alterations were similar between the 2 groups (P = 0.902 at the implant platform). The mid-facial soft-tissue level was well maintained in both groups.

Conclusions: Within the limitations of this study, for immediate implants placed into posterior sockets, customized healing abutments can facilitate closure of large sockets. Despite more pronounced incomplete defect fill, healing abutments consisting of polyether ether ketone and resin did not render an increased risk for periimplant bone loss or soft-tissue recession during the early healing period.
