Details and patient eligibility

About

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.

Enrollment: 10 patients

Sex: All

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

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

Exclusion criteria

• evidence of systemic or psychic pathology that contraindicates implant treatment.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Triple Blind

---

10 participants in 4 patient groups, including a placebo group

Mechanized parallel abutments

Placebo Comparator group

Description:

Implants were immediately covered with this type of abutments after insertion. This is the most common procedure. It would be the gold standard

Treatment:

Device: dental implant with transepithelial abutments manufactured by Galimplant Dental System (Spain)

Anodized parallel abutments

Experimental group

Description:

Implants were immediately covered with this kind of abutments after insertion. Only the surface treatment varies to the gold standard

Treatment:

Device: dental implant with transepithelial abutments manufactured by Galimplant Dental System (Spain)

Mechanized convergent abutments

Experimental group

Description:

Implants were immediately covered with this kind of abutments after insertion. Only the geometry of the emergence profile varies with regards to the gold standard

Treatment:

Device: dental implant with transepithelial abutments manufactured by Galimplant Dental System (Spain)

Anodized convergent abutments

Experimental group

Description:

Implants were immediately covered with this kind of abutments after insertion. Both the surface treatment and the geometry vary with regards to the gold standard
