This study was conducted to evaluate the influence of concave machined and concave microgrooved profiles of the transmucosal portion of implants on early peri-implant tissue regeneration. We assessed implants with 3 different transmucosal profiles: the bevel group that had only a bevel in the transmucosal part, bioseal group and bioseal/groove group that had a micro-groove in the S-shaped portion of the implant. A total of 36 implants (12 of each type) were placed in the edentulous mandibular ridges of 6 beagle dogs. We used radiographs to investigate the mesio-distal change of the marginal bone. Bucco-lingual bone resorption and soft tissue reactions were evaluated histologically. Radiographic and histological analysis did not show any difference in mesio-distal or bucco-lingual marginal bone resorption among any of the 3 groups (p > 0.05). The bioseal and bioseal/groove groups had more rigid connective tissue attachment than that in the bevel group. However, the bevel group had significantly long junctional epithelium attachment and the bioseal and bioseal/groove groups had long connective tissue attachment (p < 0.05). Implants with S-shaped concavity of the transmucosal portion resulted in a firmer connective tissue barrier, and thus, a better soft tissue regeneration, than implants with straight bevel.
