Conditions

Outcome Measures

Primary Outcomes (1)

  • Changes in horizontal alveolar ridge width from pre-operatively (baseline) to 12 months after implant loading.

    Horizontal alveolar ridge changes in being assessed in the regenerated area. This outcome will be evaluated from pre-operatively (baseline), to 12 months after implant loading by measuring the alveolar ridge width at various points on the cross-sectional images using data obtained from CBCT scans.

    From pre-operatively (baseline) to 12 months after implant loading.

Secondary Outcomes (3)

  • Implant failure

    At 6 months (T6), and at 18 months (T18) after implant placement.

  • Complications

    6 months

  • Regrafting necessity

    At 6 months (T6).

Study Arms (2)

Alveolar ridge augmentation without ABG

ACTIVE COMPARATOR

Horizontal ridge augmentation using guided bone regeneration without autogenous block graft (ABG)

Procedure: Horizontal ridge augmentation

Alveolar ridge augmentation with ABG

EXPERIMENTAL

Horizontal ridge augmentation using guided bone regeneration with autogenous block graft (ABG).

Procedure: Horizontal ridge augmentation

Interventions

Surgical procedures performed to provide the alveolar ridge with enough width and height to allow for the prosthetically driven implant placement.

Also known as: Alveolar ridge augmentation, Bone grafting

Eligibility Criteria

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

You may qualify if:

  • years old, who required an implant supported restoration in at least one site, with severe atrophy of the alveolar ridge in the horizontal plane (class III-IV atrophy according to Cawood and Howell classification),
  • adequate oral hygiene
  • no history of previous bone augmentation procedures at the implant site, and
  • able to understand and sign an informed consent form.

You may not qualify if:

  • uncontrolled systemic conditions, irradiation in the head and neck area, - immunosuppressed or immunocompromised,
  • presented with oral disorders (such as lichen planus),
  • treated or under treatment with intravenous amino-bisphosphonates,
  • untreated periodontitis, poor oral hygiene and motivation,
  • parafunctional habits,
  • pregnant or lactating,
  • drug or alcohol abuse,
  • psychiatric disorders,
  • a history (within the last 3 months) of using (at least weekly or more frequently) smokeless chewing tobacco, smoking a pipe, cigar or cigarette (at a rate of more than 10 cigarettes per day),
  • acute/chronic infection/inflammation in the area, or
  • an extraction with less than 3 months of healing

Masking Details
Outcome measurements will be recorded by an examiner, who will not participate in any study procedure, and will be blind to the allocated treatment. This blinded examiner will be trained and calibrated to perform measurements. A dentist who is blinded to the treatment protocol will performe all radiographic measurements.
