Brief summary
Objective: The aim of this prospective observational clinical study is to evaluate the bone level changes in a new implant design, fully tapered and platform switching with the one-time one-abutment protocol after one year of loading. Material and methods: Thirty patients received 1 or 2 implants (6, 8 and 10 mm in length, 3.5, 3.75 or 4.5 mm diameter and bone level design) to replace a single or multiple gap. Radiographic, clinical, esthetic and survival success rate were evaluated after one year of loading. Results: At 12 months post final loading, there were no peri-implant bone loss in any of the cases. Mean marginal crestal bone loss between surgery and crown placement was 0.19 ± 0.17 (p \<0.0001). Between surgery and 12 months of follow-up, the mean marginal crestal bone loss was 0.25 ± 0.24 (p \<0.0001). There were a SSD between 1 year follow-up and crown placement in PI in the mesial (0.33 ± 0.54 p= 0.003) and distal aspect (0.5 ± 0.73 p= 0.001). The PPD was SSD deeper at 1 year follow-up than at crown placement only in the mesial and distal probing (averaged depth=0.75 and p\<0.0005). No statistically significant differences were found for any of the other clinical and est
Interventions
DEVICEDENTAL IMPLANT
The study implants were 3.5, 3.75 or 4.5 mm implant diameter, Straumann® BLX implant SLActive® Roxolid® (Institut Straumann AG, Basel, Switzerland) and the abutment was a 0 °, 2.5 mm of height Straumann® Screw-retained Abutment. The length of the implants was 6, 8 and 10 mm. The 6 mm implant is only commercially available in 3.75 and 4.5 diameter.

Inclusion criteria
* Males or females with, at least 18 years old. * Single and multiple gaps (premolars & molars) that require single and partial fixed restorations (2 implants, 1 pontic). * Adequate bone quantity at the implant site to allow the placement of diameter 3.5, 3.75 or 4.5 mm and lengths of 6 mm, 8 mm, 10 mm, 12 mm or 14 mm. * Patients had to be informed of the follow up visits and willing to attend to the clinical centre for these appointments.
