NCT03774888

Brief Summary

This study will compare two commonly used soft tissue grafting techniques (connective tissue graft, CTG vs Acellular Dermal Matrix, ADM) to augment the soft tissue at the time of lateral ridge augmentation procedure. Following ridge augmentation procedure, most of the times there is a need for soft tissue augmentation to change the quality of the tissue around future implant's site. To our knowledge, the influence of soft tissue augmentation at the time of ridge augmentation procedure has not been tested defects.

Outcome Measures

Primary Outcomes (4)

  • Measure Changes Clinically in Crestal Soft Tissue Thickness (in mm)

    The changes in clinical vertical crestal soft tissue thickness by using an endodontic file and periodontal probe.

    From baseline to 6 months

  • Measure Changes Digitally in Crestal Soft Tissue Thickness (in mm)

    The changes in soft tissue thickness digitally with superimposition of the intraoral scan and cone-bone computed tomography scan.

    From baseline to 6 months

  • Measure Changes Clinically in Soft Tissue Thickness at 4mm Apical From Gingival Margin

    The changes in clinical soft tissue thickness at 4mm apical form the gingival margin by using an endodontic file and periodontal probe.

    From baseline to 6 months

  • Measure Changes Digitally in Soft Tissue Thickness at 4mm Apical Form Gingival Margin

    The changes in soft tissue thickness digitally with superimposition of the intraoral scan and cone-bone computed tomography scan.

    From baseline to 6 months

Study Arms (3)

connective tissue graft

EXPERIMENTAL

Connective tissue grafting (CTG) will be placed at the time of lateral ridge augmentation.Following the placement of the bone graft and the membrane, a CTG will be harvested and sutured to the membrane and then the flaps passively sutured on top on the bone and soft tissue graft

Procedure: Connective tissue graft at time of bone graft

Acellular Dermal Matrix

EXPERIMENTAL

Acellular Dermal matrix (ADM) will be placed at the time of lateral ridge augmentation.Following the placement of the bone graft and the membrane, an ADM will be sutured to the membrane and then the flaps passively sutured on top on the bone and soft tissue graft

Procedure: Acellular Demal Matrix at time of bone graft

No soft tissue graft (Control)

ACTIVE COMPARATOR

Control group where no soft tissue graft is added to the lateral ridge augmentation.Following the placement of the bone graft and the membrane, the flaps passively sutured on top on the bone. No soft tissue graft will be added.

Procedure: No soft tissue grafting at time of bone graft

Interventions

following the placement of the bone graft and the membrane, a CTG will be harvested and sutured to the membrane and then the flaps passively sutured on top on the bone and soft tissue graft
