Split-ridge Technique and guided bone regeneration: current indications and predictability

Introduction: Guided bone regeneration (GBR) is the most well documented method of bone augmentation in localized bone areas. Splitridge technique (SRT) is an alternative option to treat alveolar ridge deficiencies and provide condition for implant placement. Thus, the aim of the present case reports is to simplify the current indications and predictability of SRT or GBR in daily clinic. Description: Two patients willing to have implant placement in an atrophic ridge were submitted to two different surgical techniques for bone augmentation. In case one, the patient had SRT performed with a placement of bone substitute and implant placement at the same time of augmentation. Three months after surgery the implant was ready for restoration. In the second case, GBR technique with tenting screws and fixation pins was performed, associated with bone substitute and resorbable collagen membrane. Six months later, implant surgery was done and eight weeks after placement, implants were ready for prosthetic rehabilitation. Discussion: Both procedures can be used for rehabilitation with implants in partially edentulous patients, provided their indications are respected. Conclusions: The predictability of SRT and GBR procedures in terms of survival and success rates seems to be similar. Proper indication according to location, type and extension of bone defect and surgeons’ skills are decisive factors for the indication of one procedure over another.
