The aim of this study is to assess the surface roughness of the implant-retained mandibular bar overdenture (BOD) and the implant-retained mandibular ball joint overdenture (BJOD) in jaw and its relation with the adhesion of molds and yeasts and mesophyll aerobe, in time 30 and 180 days in mouth.
Five-systems titanium bar CARES and synOcta Straumann Dental Implant System, Holding AG Inc., Basel, Switzerland (BOD), and five-systems joint ball Klockner Implant System; Soadco Inc., Escaldes-Engordany; Andorra (BJOD), were used in two parallel groups of five participants, in an essay to simple blind person. To 30 and 180 days, the overdentures were withdrawn and evaluated the Ra: ųm. SJ-301 Mitutoyo Corporation Inc., Kanagawa, Japan, and the adhesion of microorganisms (colony-forming unit/ml).
The results were as follows: the : Um (30 and 180): BOD, 0.965-1.351; BJOD, 1.325-2.384. Adhesion: Molds and yeasts, BOD, 2.6 × 10 and 4.6 × 10; BJOD, 3.0 × 10 and 5.3 × 10. Adhesion: Mesophyll aerobe, BOD, 3.8 × 10 and 5.8 × 10; BJOD, 4.3 × 10 and 7.1 × 10.
At 30 days ( = 0.489), there were no differences in BOD and BJOD for adhesion of molds and yeasts and mesophyll aerobe between both overdentures. At 180 days ( = 0.723), there were differences in the adhesion of mold and yeast and mesophyll aerobe, being greater in BJOD.
本研究旨在评估下颌种植杆式覆盖义齿（BOD）和下颌种植球铰式覆盖义齿（BJOD）在口腔内30天和180天时的表面粗糙度，及其与霉菌、酵母菌和叶肉需氧菌黏附的关系。
两组平行实验，每组五名参与者，分别使用瑞士巴塞尔的CARES五系统钛杆和士卓曼牙科种植系统（BOD），以及安道尔埃斯卡尔德斯 - 恩戈尔达尼的索德科公司的Klockner种植系统五系统关节球（BJOD），进行单盲试验。在30天和180天时，取出覆盖义齿，使用日本神奈川的三丰公司的SJ - 301测量表面粗糙度Ra（μm），并评估微生物黏附情况（菌落形成单位/毫升）。
结果如下：表面粗糙度Ra（μm，30天和180天）：BOD为0.965 - 1.351；BJOD为1.325 - 2.384。霉菌和酵母菌黏附情况：BOD为2.6×10和4.6×10；BJOD为3.0×10和5.3×10。叶肉需氧菌黏附情况：BOD为3.8×10和5.8×10；BJOD为4.3×10和7.1×10。
在30天时（P = 0.489），两种覆盖义齿在霉菌、酵母菌和叶肉需氧菌的黏附方面没有差异。在180天时（P = 0.723），霉菌、酵母菌和叶肉需氧菌的黏附存在差异，BJOD的黏附情况更严重。
