Abstract

OBJECTIVES

The aim of this study was to assess the clinical outcomes achieved with Computer-Assisted Design/Computer-Assisted Manufacturing implant abutments in the anterior maxilla.

MATERIAL AND METHODS

Nineteen patients with a mean age of 41 (range form 26 to 63) years, treated with 21 single tooth implants and 21 Computer-Assisted Design/Computer-Assisted Manufacturing (CAD/CAM) abutments in the anterior maxillary region were included in this study. The patients followed 4 criteria of inclusion: (1) had a single-tooth implant in the anterior maxilla, (2) had a CAD/CAM abutment, (3) had a contralateral natural tooth, (4) the implant was restored and in function for at least 6 months up to 2 years. Cases without contact point were excluded. Presence/absence of the interproximal papilla, inter tooth-implant distance (ITD) and distance from the base of the contact point to dental crest bone of adjacent tooth (CPB) were accessed.

RESULTS

Forty interproximal spaces were evaluated, with an average mesial CPB of 5.65 (SD 1.65) mm and distal CPB of 4.65 (SD 1.98) mm. An average mesial ITD of 2.49 (SD 0.69) mm and an average distal ITD of 1.89 (SD 0.63) mm were achieved. Papilla was present in all the interproximal spaces accessed.

CONCLUSIONS

The restoration of dental implants using CAD/CAM abutments is a predictable treatment with improved aesthetic results. These type of abutments seem to help maintaining a regular papillary filling although the variations of the implant positioning or the restoration teeth relation.

摘要

目的

本研究旨在评估计算机辅助设计/计算机辅助制造种植基台在上颌前部的临床效果。

材料与方法

本研究纳入了19例平均年龄为41岁（范围26至63岁）的患者，他们在上颌前部接受了21颗单颗牙种植及21个计算机辅助设计/计算机辅助制造（CAD/CAM）基台的治疗。患者需符合4项纳入标准：（1）上颌前部有单颗牙种植；（2）有CAD/CAM基台；（3）对侧有天然牙；（4）种植体已修复并正常使用至少6个月至2年。无接触点的病例被排除。评估邻间隙乳头的有无、牙-种植体间距（ITD）以及从接触点底部到相邻牙牙槽嵴骨的距离（CPB）。

结果

评估了40个邻间隙，近中CPB平均为5.65（标准差1.65）mm，远中CPB平均为4.65（标准差1.98）mm。近中ITD平均为2.49（标准差0.69）mm，远中ITD平均为1.89（标准差0.63）mm。所有评估的邻间隙均有乳头存在。

结论

使用CAD/CAM基台修复牙种植体是一种可预测的治疗方法，美学效果更佳。尽管种植体位置或修复牙关系存在差异，但这类基台似乎有助于维持正常的乳头充盈。
