Introduction: Alveolar ridge atrophy is characterized by resorption of alveolar bone due to tooth loss, it is difficult to place an implant in such cases. Numerous techniques were mentioned for reconstruction of the atrophic mandibular ridge. Tenting of the soft tissue matrix allow maintaining space for the graft material.
Objectives: The primary aim of this trial is clinical and radiographic evaluation of the tent pole implant placement simultaneously with GBR using a mixture of autograft and xenograft material and non-resorbable membrane (PTFE) for single stage management of vertically deficient mandibular alveolar ridge. The secondary aim is to evaluate the soft tissue healing around implant together with the implant crestal bone level.
Materials and methods: Fifteen implants were placed in this clinical trial. Patients had vertical bone augmentation to their mandibular edentulous ridge and implant placement in one step procedure. Patient's age ranges from 30 to 45 years. Implants were placed in the alveolar ridge with an average of 3 to 5 mm of their length were exposed, a mixture of autograft combined with xenograft were placed around implants in a tenting fashion covered with PTFE membrane and pined in place with tack pins.
Results: Bone height showed a statistically significant difference identified by cone beam computed tomography (CBCT).
Conclusion: From the results of this study, the single stage management of vertically deficient posterior mandibular edentulism using implant tent -pole grafting technique with simultaneous guided bone regeneration is a technique of high reliability in restoring mandibular vertical bone loss.
