About

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

Enrollment: 104 patients

Sex: All

Ages: 18 to 90 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• severe medical conditions that could affect periodontal health and peri-implant tissue response
• use of drugs correlated to periodontal hypertrophy
• bone volume that required bone augmentation procedures before implant placement as well as soft tissue graft or any kind of peri-implant tissue engineering
