Soft and Hard Tissue Changes around Tissue‐Oriented Tulip‐Design Implant Abutments: A 1‐Year Randomized Prospective Clinical Trial

Abstract

Use of the new TA, with its significantly downsized diameter, resulted in reduced bone loss at 1 year. Further research will be required to assess the long-term effect of this abutment on peri-implant health.

Does the platform switching implant affect the crestal bone level? A systematic review and meta-analysis

“…We identified 19 potentially eligible studies (25 reports) (14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32) . The detailed search results are depicted in PRISMA flow diagram (Figure 2).…”

“…In two studies (19,25) no information was provided regarding generating the random sequence, while in the rest of the included trials adequate methods of randomization were described (14-18, ,20-24) . Regarding allocation concealment, it was unclear in two studies how the random sequence was concealed (18,19) , while all the remaining trials provided adequate description of their concealment method. (14-17,20,-25) .…”

“…We judged the risk of detection bias to be low in objective outcomes, and high in patient reported outcomes since lack of blinding can potentially introduce bias for this class of outcomes through multiple pathways (different expectations from the two groups and biased assessment of the effect) Higgins (13) . In seven studies, all the participants randomized were available for all follow-up duration with no drop outs or exclusions (15,16,18,19,20,21,25) . In four studies, the risk of attrition bias was high (14,17,22,24) .…”

“…We assessed five trials to be at high risk of reporting bias due to failure to report key outcomes that are expected to be reported for such studies (14,17,18,22,25) , while in all the remaining studies, the risk of bias was low (15,16,19,20,21,23,24) .…”

“…Seven trials reported implant failure (15,16,18,19,21,23,25) . There was no difference between platform switching and platform matching in implant failure after 1-3 years of follow up (RR 0.32, 95% CI 0.01 to 7.70; participants = 475; studies = 7; I 2 = 0%) (Analysis 1.1).…”
