With the prevalence of peri‐implantitis increasing, management of the disease is an important therapy to consider. The goal of a dual augmentation technique in the treatment of peri‐implantitis is to address hard and soft tissue deficiency simultaneously. This report of two cases presents clinical and radiographic outcomes for surgical treatment of peri‐implantitis with a dual augmentation technique in advanced peri‐implantitis cases with inadequate keratinized tissue. Case Series: Two patients diagnosed with advanced peri‐implantitis exhibiting bleeding on probing (BOP), probing depth (PD) >6 mm, and bone loss >3 mm were treated. Affected implants were treated with specific surface decontamination protocol followed by using a combination of recombinant human platelet‐derived growth factor with a mixture of freeze‐dried bone allograft and deproteinized bovine‐derived bone. Subsequently, acellular dermal matrix was used as a membrane to cover defects and augment soft tissue volume at the same time. The dual augmentation technique demonstrated significant radiographic bone gain in 3 to 5 months and increase in mucosal thickness that appeared to be stable during the follow‐up period of 15 months. Surgical reentry provided further evidence to confirm radiographic bone fill. Clinical examination also revealed significant reduction in PD and BOP. Conclusion: Within the limitations of this report, treatment of peri‐implantitis with a dual augmentation technique appeared to enhance bone and soft tissue regeneration in advanced peri‐implantitis cases with existing mucogingival defects.
