Effect of Shape and Surface Treatment of the Transmucosal Abutments on Peri-implant Health.

Not Applicable

Completed

• Conditions: Edentulous; Alveolar Process, Atrophy

• Registration Number: NCT05284461
• Lead Sponsor: University of Salamanca

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.

Primary Outcome Measures

Name	Time	Method
Density of the peri-implant soft tissues	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	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	3 months after healing	Histological assessments as ordinal variables of the grade of inflammatory infiltrate (none, minor, major)according to standard guidelines.
