immediate

This study was aimed to compare the treatment success rate following immediate loading of single Vs. double retained Mandibular over dentures In this randomized clinical trial 20 subjects with problematic conventional complete dentures were studied. The chief complaint was poor retention of the mandibular dentures. Subjects were divided randomly in to two groups(A or B). All subjects received 3 (3/8 ´ 10mm) implants including one implant in the symphysis area located in the midline of mandible and two others located10-12 mm a way from midline. In group A, midline Implants were loaded immediately after surgery and the lateral Implants remained unloaded. In group B: lateral implants were loaded immediately and midline implants remained unloaded. Six months later,Denture retention, implant stability and periodontal parameters (PPD, BOP), crestal bone loss and survival rate of Implants were measured. The results within each group were analyzed using Pair t.test while results between the two groups were analyzed using Mann-whitney, T.test and Fisher tests. No significant difference in denture retention was reported(P < 0/6)with respect to implant stability (P < 0/3), crestal bone loss (P<0/3), PPD(P<0/7), BOP (P < 0/7) and survival of implant(P < 0/9) between over dentures retained by single implant or double implant. Single retained mandibular overdenture may be considered as an alternative treatment plan For socioeconomically under privileged patients.
