Bone Loss, Implant Tissue Failure, Periodontal Bone Loss
Conditions
Brief summary
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

* Missing teeth * good oral hygiene * good systemic health
Exclusion criteria
* lactation * pregnancy * heavy smoking (more than 20 cigarettes/day) * 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
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| height of the peri-implant mucosa (MH) | 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. |
| The width (MT) of the peri-implant mucosa | 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. |
