Guided Bone Regeneration Using Fixed vs Non-Fixed Resorbable Collagen Membranes

Guided Bone Regeneration Using Fixed vs Non-Fixed Resorbable Collagen Membranes: A Randomized Controlled Clinical Trial

Sponsor

Universitat Internacional de Catalunya

Enrollment

26 participants

Start Date

Nov 5, 2020

Study Type

INTERVENTIONAL

Conditions

Bone Resorption

Summary

The aim of this clinical trial is to compare the horizontal bone gain when grafting a bone substitute with non fixed resorbable collagen membranes (control group), versus fixed resorbable collagen membranes (test group) in resorbed ridges requiring Guided Bone Regeneration (GBR) to facilitate implant placement at 6 months.

Eligibility

Min Age: 18 Years

Inclusion Criteria8

Men and women over 18 years old or older
Patients requiring Guided Bone Regeneration due to insufficient ridge width(≤5mm) to place dental implants, with sufficient vertical ridge height (≥9mm) from vital anatomical structures (the inferior alveolar nerve in the Mandible, or the sinus in the Maxilla)
One or more teeth missing in posterior zone (Premolars, and Molars)
Absence of active Periodontal disease
Good level of oral hygiene (Plaque index \<25%)
Absence of systemic diseases that could influence the outcome of the therapy (Uncontrolled diabetes, osteoporosis, bisphosphonate medications)
Non smokers or light smokers (\<10 cigarettes per day)
Informed consent signed

Exclusion Criteria6

Patients with sufficient ridge width (\>5 mm) and height (≥9mm) from vital anatomical structure) requiring no GBR to place dental implants
Patients with severe horizontal and vertical defects requiring other surgical techniques.
Long-term non-steroidal anti-inflammatory drug therapy (3months).
Lactating females or currently pregnant women.
Severe cognitive or psychiatric disorders.
Unwillingness to return for follow-up examination.

Interventions

PROCEDUREHorizontal GBR with the use of non-resorbable pins for the stabilization of the collagen membrane

Horizontal Guided Bone Regeneration, with a mixture of xenograft (Cerabone®) and allograft (Maxgraft®), on a 50-50 mixture ratio, grafted in the area required to be augmented, and then covered by a collagen membrane (Jason® membrane), being fixed with non-resorbable pins (Test Group).
