简要总结
The substitution of a tooth with a fixture often induces undesired morphological changes, resulting in a deterioration of the aesthetic appearance. The purpose of this study is to compare the soft tissue behavior next to two different implant connections: 5° (group 1) and 35° hexed (group 2), conical, internal with switching platform design after 12 months of functional provisionalization

结局指标
主要结局
The width (MT) of the peri-implant mucosa
时间窗: 12 months
was calculated from the vestibular shoulder of the analogue to the external mucosa point perpendicular to the implant major axis digitally calculated by 3D software Gom.
height of the peri-implant mucosa (MH)
时间窗: after 12 months
This measurement (MH) corresponds to the depth of the implant referred to the most coronal point of the buccal mucosa measured according to the main implant axis digitally calculated by 3D software Gom.
