Bone regeneration of horizontal defects in the posterior mandible: 1-year prospective study results

INTRODUCTION

Alveolar ridge defects caused by tooth extraction, trauma or periodontal diseases often require surgical procedures to allow implant-supported prosthodontic rehabilitation. Guided bone regeneration (GBR) utilizing bone graft substitutes and collagen membranes is considered a preferred treatment option able to provide bone of sufficient volume and quality for implant placement (1,2). To ensure long-term success, however, the augmented bone should also promote stable and healthy response of the peri-implant tissues.

The aim of this multicenter prospective study was to evaluate GBR in severe horizontal bone defects using bovine bone graft material (creos xenogain, Nobel Biocare) and collagen membrane (creos xenoprotect, Nobel Biocare) prior to implant placement.

Highlights

  • Significant bone width gain 8 months post GBR surgery: 4.0 ±1.5 mm at 1 mm and 4.8 ± 1.7 mm (n=45) at 3 mm from the top of the crest. 
  • Successful placement of 91 implants in 43 patients. 
  • High cumulative implant survival and success rates of 100% and 96.3%, respectively, from definitive prosthesis placement to 1-year follow-up.

Werner Zechner & Bastian Wessing: Simultaneous GBR and implant placement in horizontal ridge augmentations

Guided bone regeneration (GBR) is a well established technique for horizontal alveolar ridge augmentation. Since the first publications in the early 1980’s extensive research was carried out focusing on different membranes, grafting materials, and timing of implant placement, as...

Horizontal and vertical ridge augmentation of a knife-edge ridge

A 54-year-old man presented with missing right lower teeth and ridge deficiency. Horizontal and vertical augmentation by GBR (Guided Bone Regeneration) was carried out using the “Tenting Screw Technique”. Two implants and a free gingival graft were placed.
