The influence of abutment design on bone resorption around immediately loaded and osseointegrated implants used to support fixed partial prostheses was investigated in a 1-year study. One hundred ten implants were placed in 24 anterior partially edentulous maxillae. The probing depths of each implant were measured 6 and 12 months after abutment placement and analyzed statistically. Total probing depth was 1.75 ± 0.75 mm. There were significant differences between non- and submerged implants with angled abutments and between submerged implants with straight and angled abutments. No significant differences were observed between non- and submerged implants with straight abutments and between nonsubmerged implants with straight and angled abutments. Bone resorption around dental implants is influenced by the abutment design and the associated implantation protocol.
一项为期 1 年的研究调查了基台设计对支持固定局部义齿的即刻负载和骨整合种植体周围骨吸收的影响。110 个种植体被植入 24 例上颌前部部分缺牙区。在基台放置后 6 个月和 12 个月测量每个种植体的探诊深度，并进行统计学分析。总探诊深度为 1.75 ± 0.75mm。非埋入式和带角度基台的埋入式种植体之间以及带直基台和角度基台的埋入式种植体之间存在显著差异。而带直基台的非埋入式和埋入式种植体之间以及带直基台和角度基台的非埋入式种植体之间无显著差异。种植体周围的骨吸收受基台设计和相关种植体方案的影响。
