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

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

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.

Inclusion Criteria:

• totally edentulous patients in the upper arch and carriers of conventional complete dentures for more than ten years, without temporomandibular disorders
