NCT03946020

Brief Summary

This study will be an open, prospective, split-mouth, randomised controlled clinical trial. A total of 14 patients searching for oral implant treatment and where a GBR procedure is indicated per implant treatment will be enrolled. All patients have to fulfill all of the inclusion criteria and none of the exclusion criteria. From all patients clinical photos will be taken. Two sites within a patient will be randomly allocated to the 'autologous bone chips and DBBM or 'DBBM particles alone' group. The study will be 1 year follow-up study comprising 9 visits

Outcome Measures

Primary Outcomes (1)

  • Horizontal and vertical bone augmentation

    The change of dimension was assessed comparing Cone Beam Computed Tomography scans (CBCT)

    16 weeks

Secondary Outcomes (2)

  • Success of grafting procedure as assessed by clinical interpretation

    1 year

  • Marginal bone level alterations assessed on peri-apical radiographs using software (ImageJ)

    1 year

Study Arms (2)

Augmentation with autologous bone + DBBM

ACTIVE COMPARATOR

A layer of autogenous bone chips was placed on the implant surface. On top of this a layer of DBBM (Bio-Oss™, Geistlich®, Wolhusen, Switserland) was placed, thereafter covered with a collagen membrane.

Procedure: Guided bone regeneration with or without autologous bone

Augmentation with DBBM

EXPERIMENTAL

A layer of DBBM was placed on the implant surface and thereafter covered with a collagen membrane. Care was taken to make both augmentations as comparable as possible by weighting the used amount of graft material.

Procedure: Guided bone regeneration with or without autologous bone

Interventions

Autogenous bone chips were collected. On each side a bone level implant was placed. The bone dehiscence was measured and was thereafter treated according to the GBR protocol. A resorbable native collagen was adapted to the defect.
