The effect of three different periodontal pre-treatment procedures on the success of telescopic XXXX .

@entity548 @entity235 @entity7606 @entity3628 @entity92 @entity10273
In this prospective study, 120 teeth consisting of maxillary and mandibular @entity235 and premolars were divided into three groups each containing 40 teeth. The teeth were assigned randomly in quadrants to three different periodontal treatment protocols. The first group was treated with professional prophylaxis only. The second group received additional deep scaling. With the third group, additional surgical periodontal flap surgery and scaling was performed. Both @entity548 index (PBI) and @entity92 ( @entity92 ) were evaluated before, during and after treatment. During the subsequent prosthetic treatment phase all teeth were then used as telescope abutments supporting a removable prosthesis. The documentation of the @entity10273 ( @entity10273 ) was then used as a clinical parameter. One year after the incorporation of telescopic @entity7606 ( @entity7606 ), @entity92 , PBI and @entity10273 were again evaluated. The resulting periodontal parameters were compared between the different groups using the @entity3628 ( @entity3628 ) repeated measures and the Kruskal-Wallis test for non-parametric variables. Differences within the three treatment groups were determined using the t-test, e.g. the Wilcoxon test for dependent variables (P < 0.05). A significant decrease in inflammatory indices (PBI) was found for all types of periodontal treatment (P < 0.03 for all groups). Additionally, the reduction in @entity92 was significant for all of the three groups (P < 0.001 for all groups). The greatest reduction in @entity92 was observed in the group in which a surgical approach was used. Evaluation of the @entity10273 after the incorporation of the telescopic @entity7606 showed that tooth position did not influence the periodontal prognosis and that the use of telescopic @entity7606 exerted no ascertainable negative influence on the periodontium of the abutment teeth.
