With conflicting results in the literature and various manufacturer recommendations, it is not known what cementation protocols are currently being used for implant restorations in US dental schools.
The purpose of this survey was to determine what dental cementation protocols are taught and recommended by 62 US dental schools and postgraduate programs.
From February to September 2008, 96 questionnaires consisting of 8 questions were sent to the chairperson or director of restorative departments, advanced prosthodontics programs, and implant programs. The questionnaire asked recipients which implant manufacturers provided the products used at their dental schools. Additionally, recipients were queried as to the choice of material and techniques for abutment and restoration preparations prior to definitive cementation. Data were analyzed with descriptive statistics.
A total of 68 (71%) surveys were returned, and 52 (84%) of the 62 predoctoral and postgraduate programs were represented. After deleting duplicate responses, 31 surveys were returned from restorative department chairpersons, 29 from advanced prosthodontic program directors, and 2 from implant program directors. Frequency of responses to each question was tabulated, and results are presented in 3 sections. For all 3 types of programs, Nobel Biocare was reported to be the most widely used implant system, followed by Biomet 3i, Straumann, Astra Tech, and Zimmer Dental systems. The most commonly used technique prior to definitive cementation is to airborne-particle abrade the intaglio surface of the restoration. Resin-modified glass ionomer is the most frequently used luting agent for cementing implant restorations. The 5 most commonly used materials to fill screw access openings are cotton pellets, composite resin, rubber-based material, gutta-percha, and light-polymerized provisional composite resin. Most predoctoral and postgraduate programs teach students to fill the screw access opening completely to the occlusal surface.
There are a wide range of implant cementation protocols and materials used; however, some common trends were identified among predoctoral and postgraduate programs.
由于文献中存在相互矛盾的结果和各种制造商的建议，目前尚不清楚美国牙科学校在种植体修复中使用的是什么粘结方案。
本调查的目的是确定 62 所美国牙科学校和研究生课程教授和推荐哪些牙科粘结方案。
2008 年 2 月至 9 月，向修复科主任、高级修复专业课程主任和种植科主任发送了 96 份包含 8 个问题的调查问卷。问卷询问收件人哪些种植体制造商为其牙科学校提供产品。此外，还询问收件人在最终粘结前，对基台和修复体预备的材料和技术的选择。数据采用描述性统计方法进行分析。
共收回 68 份（71%）调查问卷，其中 62 个本科前和研究生课程中有 52 个（84%）课程得到了代表。在删除重复回复后，从修复科主任处收回 31 份调查问卷，从高级修复专业课程主任处收回 29 份，从种植科主任处收回 2 份。对每个问题的回复频率进行了制表，结果分为 3 个部分呈现。对于所有 3 种类型的课程，诺贝尔生物公司报告的使用最为广泛，其次是 Biomet 3i、士卓曼、AstraTech 和 Zimmer Dental 系统。在最终粘结前最常用的技术是对修复体的凹面进行空气喷磨。树脂改性玻璃离子水门汀是最常用于粘结种植体修复体的粘固剂。最常用于填充螺丝通道开口的 5 种材料是棉片、复合树脂、橡胶基材料、牙胶和光固化临时复合树脂。大多数本科前和研究生课程都教导学生将螺丝通道开口完全填满到咬合面。
目前使用的粘结方案和材料种类繁多，但本科前和研究生课程中存在一些共同的趋势。
