This study estimated the 1-year survival of early-loaded Defcon treatment surface Avantblast (TSA) implants (Impladent; Sentmenat, Barcelona, Spain) and compared this success rate with those reported in the literature for conventionally loaded implants.
In this retrospective case series study, the sample comprised subjects receiving 1 or more implants placed and loaded early between 2002 and 2005. The definition of implant success was based on clinical and radiologic Buser's criteria; all patients had a follow-up period of 1 year. Information was collected on patient age, gender, oral hygiene, and smoking status; implant location, diameter, and length; and prosthetic parameters for performing an implant survival analysis.
A total of 642 Defcon TSA implants were placed (318 in the maxilla and 324 in the mandible) in 192 patients, who were rehabilitated with 298 prostheses. The implant survival rate was 98.13%. A review of the literature on early loading between 2001 and 2005 revealed a success rate of 98.4%.
Our recorded success rate is similar to that found in the reviewed literature corresponding to large series of patients subjected to early implant loading.
本研究评估早期负载的Defcon治疗表面Avantblast（TSA）种植体（Impladent；西班牙巴塞罗那森特马的Sentmenat公司）的1年生存率，并将该成功率与文献中报道的传统负载种植体的成功率进行比较。
在这项回顾性病例系列研究中，样本包括2002年至2005年间接受1枚或更多枚早期植入和负载的种植体的受试者。种植体成功的定义基于临床和放射学的Buser标准；所有患者的随访期均为1年。收集了患者年龄、性别、口腔卫生和吸烟状况；种植体位置、直径和长度；以及用于进行种植体生存分析的修复参数等信息。
共为192例患者植入了642枚Defcon TSA种植体（上颌318枚，下颌324枚），并用298个修复体进行了修复。种植体生存率为98.13%。对2001年至2005年间早期负载的文献回顾显示成功率为98.4%。
我们记录的成功率与回顾文献中对大量早期种植体负载患者的研究结果相似。
