NCT06334159

Brief 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.

Outcome Measures

Primary Outcomes (2)

  • Horizontal Bone Gain

    To compare the horizontal bone gain when grafting a mixture of xenograft and allograft (50/50) with non-fixed resorbable collagen membranes (control group) versus fixed resorbable collagen membranes (test group) in resorbed ridges requiring GBR to facilitate implant placement at 6 months. Along the 6 months, 3 Cone Beam Computed Tomography scans (CBCT) will be needed. At baseline (T1), the first CBCT will be taken before performing any surgical procedure to measure the initial width of the ridge. Immediately after the GBR (T2), a second CBCT scan will be taken, which will be useful to measure new ridge width in each group. Finally, at 6 month follow-up a third CBCT scan will be taken (T3) in order to assess the difference with T1 regarding amount of bone gain horizontally, and with T2 regarding horizontal dimensional stability of the grafted bone in each of the 2 groups.

    T3: 6 months after the Horizontal GBR

  • Bone Width Gain

    To compare the bone width gain between the test group and control group, 6 months after the horizontal GBR. A caliper will be used in order to evaluate and compare the bone width gain at T1, T2, and T3 between the Test and Control Groups. These measurements are performed intra-operatively before the Horizontal GBR (T1), immediately after (T2), and at 6 months (T3) at the time of implant placement. Measurements will be performed at 1cm, 3cm, and 5cm apical from the bone crest at the regenerated area.

    T3: 6 months after the Horizontal GBR

Secondary Outcomes (4)

  • Horizontal Dimensional Stability

    T3: 6 months after the Horizontal GBR

  • Post-surgical complications

    T2-T3: From the surgery to 6 months

  • Patient's satisfaction

    At 2-weeks follow up after the surgical procedure

  • Histologic examination of the augmented bone at 6 months

    At time of implant placement

Study Arms (2)

Control Group

EXPERIMENTAL

Horizontal Guided Bone Regeneration with a mixture of xenograft (Cerabone 0.5-1mm particles) and allograft (Maxgarft \<2mm particles) bone substitute (50/50) with non-fixed resorbable collagen membranes (Jason Membrane 20x30mm)

Procedure: Horizontal GBR without the use of non-resorbable pins for the stabilization of the collagen membrane

Test Group

EXPERIMENTAL

Horizontal Guided Bone Regeneration with a mixture of xenograft (Cerabone 0.5-1mm particles) and allograft (Maxgarft \<2mm particles) bone substitute (50/50) with fixed resorbable collagen membranes(Jason Membrane 20x30mm) with the use of pins (Titan Pins)

Procedure: Horizontal GBR with the use of non-resorbable pins for the stabilization of the collagen membrane

Interventions

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).

Test Group

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 left unfixed (Control Group).

Control Group

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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

You may not qualify if:

  • 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.
