Overview
Brief Summary
The aim of the research is to evaluate the clinical outcome of short dental implants, characterized by a new macro-structural design and inserted in the upper or lower jaw in patients with reduced bone volume. The clinical outcomes will be compared for different surface treatments of implant neck and those of prosthetic components.

Eligibility Criteria
Inclusion Criteria
- •healthy patients, with edentulous maxillary or mandibular ridge, requiring rehabilitation with two adjacent implants;
- •at least 6 month after extraction;
Exclusion Criteria
- •post-extractive implants;
- •sites requiring bone regeneration or maxillary sinus lift;
- •general health problems that contraindicate implant treatment.
Outcomes
Primary Outcomes
Marginal Bone remodeling around the implant
Time Frame: 0-4-12 months after implant placement
The marginal bone remodeling will be evaluated by Radiographic examination. Periapical radiographs will be performed using paralleling technique with a Rinn-type positioner, customized for each patient at implant placement (T0), prosthetic restoration delivery (T1), and after 12 months (T2).Peri-implant bone levels will be measured at each time point as the linear distance (in mm) between implant platform and bone crest at mesial and distal aspects of each implant. A positive value will be assigned if the bone crest is coronal to the implant platform, whereas a negative value will be assigned if the first bone-to implant contact is apical to the implant platform. All measurements will be performed by two examiners, using measuring software (Image J). Each measurement will be performed three times at three different points.
Secondary Outcomes
- Periodontal indexes: Probing Depth(The measurements will be performed at 4 (T1) and 12 (T2) months after implant placement.)
- Implant Stability evaluation(0-4 months.)
- Suppuration on probing(The measurements will be performed at 4 (T1) and 12 (T2) months after implant placement.)
- Bleeding on Probing(The measurements will be performed at 4 (T1) and 12 (T2) months after implant placement.)
- Plaque index of peri-implant tissues(The measurements will be performed at 4 (T1) and 12 (T2) months after implant placement.)
