简要总结
The primary outcome of the study was the vertical variation of peri-implant buccal and palatal bone level from implant placement (T0) to uncovering stage (3 months later - T1)
详细描述
despite various recommendations, there is insufficient evidence to set a threshold for minimal buccal bone thickness necessary to ensure peri-implant marginal bone stability and optimal aesthetic outcomes.
Therefore, the aim of the present multi-centre prospective study was to investigate the influence of buccal and palatal bone thickness at the time of implant placement on peri-implant bone remodeling during the submerged healing period, with a strict control of possible confounding factors.
