Introduction

Bone augmentation is frequently necessary to support dental implant placement procedures. Autogenous bone is considered to be the current gold standard for bone augmentation; however, only limited amounts of autogenous bone can be harvested at the implantation site. Furthermore this procedure may lead to morbidity problems.
 

Objectives

As an alternative, commercially available bone substitutes may be used to limit some of the drawbacks associated with autogenous bone. Straumann® BoneCeramic is a commercially available synthetic bone graft substitute comprising porous biphasic calcium phosphate, in the form of granules, which has been on the market since 2004.
In this study we report long-term implant survival rate.

Material and Methods

In all indications, with exception of bone splitting, Straumann® BoneCeramic was used in combination with autogenous bone. For vertical augmentation procedures bone particles were first fixed to the alveolar ridge and subsequently covered by the synthetic graft particles. A resorbable collagen membrane was always used to protect and stabilize the augmentation site. Implants were mostly inserted simultaneuosly into the augmented bone. Functional loading occurred between 3 and 5 months post-surgery, depending on the indication.
 

Results

Between January 2005 and December 2008 we performed 332 sinus floor elevations, 153 bone splitting procedures, 148 lateral augmentations and 37 vertical augmentations using this new material. A total of 1025 dental implants, from various different manufacturers, were inserted.
We disposed of 3 years follow data for 73 implants placed, at least 2 years follow up data for 403 implants and at least 1 year follow up data for 751 implants.
Four implants were lost, three after sinus lifts and one following vertical augmentation. The overall success rate was 99.6%.

Conclusions

The result is encouraging, also in comparison to previous data obtained with the use of autogenous bone alone. The positive influence of the material on the healing process can be related to its osteoconductive and resorption characteristics.
