title: Maintaining and attenuating periodontal tissues for aesthetic implant placement.
abstract: Alveolar ridge resorption and soft tissue recession after tooth extraction inevitably disrupted the harmonious pre-existing periodontal complex, compromising clinicians' ability to recreate successful aesthetic restorations. Although numerous surgical procedures had been advocated for the augmentation of both the alveolar ridge and its soft tissue to ideal contours, questions remain regarding viability and predictability of these procedures. This is especially critical in the maxillary anterior region, where a the condition of the soft tissue complex and its relationship to the implant restoration and its adjacent dentition often determines the implant's success. The described technique of retaining the root remnant and inducing the proliferation of the surrounding tissue in conjunction with immediate implant placement results in the preservation of existing soft and hard tissue, thus minimizing the necessity of grafting procedures and facilitating primary flap closure during implant placement.
