Sponsor's own description
The aim of the study was to compare the surface roughness (Ra) 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 to 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 To 30 to 180 days they were withdrawn and they were evaluated the Ra (Mitutoyo Surfest SJ-301® Mitutoyo Corporation Inc., Kanagawa, Japan) and the adhesion of microorganisms (CFU/ml). The Ra:um (the 30th and 180th): BOD, 0.965 - 1.351; BJOD, 1.325 - 2.384. Adhesion: molds and yeasts, BOD, 2.6 x 102 and 4.6 x 103; BJOD, 3.0 x 102 and 5.3 x 104. Adhesion: mesophyll aerobe, BOD, 3.8 x 106 and 5.8 x 106; BJOD, 4.3 x 106 and 7.1 x 107. The BOD and BJOD, present different Ra (P \< 0.05) to 30 to 180 days. To 30 days (P = 0.489) differences do not exist as regards the adhesion of molds and yeasts and mesophyll aerobe between both overdentures. To 180 days (P = 0.723) differences exist as regards the adhesion of mold and yeast and mesophyll aerobe, being major in BJOD.
