Overview
Brief Summary
The sample was comprised by 10 patients in which 40 dental implants are placed in an atrophic maxilla. All the implants were connected to 4 types of transepithelial abutment: i.e: parallel anodized abutment(n=10); parallel mechanized abutmen(n=10)t, convergent anodized abutment(n=10); and convergent mechanized abutment (n=10) three months after insertion implants were extracted with the surrounding hard and soft tissues for the histological evaluation of the clinical performance.

Outcomes
Primary Outcomes
Density of the peri-implant soft tissues
Time Frame: 3 months after healing
Histological assessments as ordinal variables of the density of the collagen fibers (low, medium, high) according to standard guidelines.
Bone to implant contact
Time Frame: 3 months after healing
It is a Percentage estimation of native bone in direct contact to implant determined by histological assessments (optical microscopy)
Peri-implant inflammation of the soft tissues
Time Frame: 3 months after healing
Histological assessments as ordinal variables of the grade of inflammatory infiltrate (none, minor, major)according to standard guidelines.
