One-year follow-up of @entity702 / XXXX alloy X commercially pure @entity702 narrow-diameter implants placed in the molar region of the mandible: a randomized controlled trial.

@entity1 @entity548 @entity604 @entity8463 @entity702 @entity3040
OBJECTIVE: To analyze @entity604 ( @entity604 ) and clinical parameters around narrow-diameter implants (NDIs - 3.3  mm) made of @entity702 / @entity8463 alloy (TiZr) in comparison with commercially pure @entity702 (cpTi) installed in the molar region of the mandible after 1  year in function. MATERIALS AND METHODS: Ten @entity1 participated in the study. A TiZr and a cpTi @entity3040 were randomly installed in contralateral molar sites of the mandible of each @entity1 in a split-mouth design. Eight weeks after healing, all metal-ceramic single crowns were adapted to the implants and @entity1 were enrolled in a plaque control program. @entity604 at the mesial and distal aspects of the implants were evaluated by comparing periapical radiographs taken immediately after prosthesis installation (T1) and 1  year after loading (T2). Clinical probing depth, @entity548 on probing, suppuration, visible plaque and implant mobility were evaluated to determine implant success and survival rates. RESULTS: Mean @entity604 at the interproximal aspects of TiZr implant sites was 0.32      0.27  mm, while at cpTi implant sites mean @entity604 was 0.35      0.24  mm (P  =  0.60). Both TiZr and cpTi NDIs presented 100% implant survival and success rates, with no significant differences in the clinical parameters studied (P  >  0.05). CONCLUSION: TiZr and cpTi NDIs presented similar outcomes after 1  year in function in the molar region of the mandible. The results suggest that TiZr and cpTi NDIs may be equally used to support single crowns in the posterior area of the mouth. However, further studies with longer follow-up periods are necessary to confirm these findings.
