简要总结
BACKGROUND: Implantdentistry has evolved over time with various novel protocols. These protocolshave guided in making the implant placement easier to a point that now theoutcomes can be predicted to a greater extent. Research using biomaterials suchas blood derived membranes and bone grafts have assisted in constant success ofthis therapy. Several strategies includingplacement of immediate implants have been proposed to preserve post extractionalveolar ridge from resorption during healing. The immediate implant treatmentprotocol serves many advantages including minimal surgical interventions, thusreducing total treatment time, preservation of adequate bone height and aestheticoutcomes especially in anterior region.
AIM: This study will be undertaken to evaluate effectiveness of implantplacement immediately followed by tooth removal with simultaneous PRFM andDFDBA grafting using a two-stage protocol.
MATERIAL AND METHODS: Thisstudy will be performed over one year period. Twelve patients, each having onetooth indicated for extraction in the maxilla and/or mandible will be selected.Implants will be placed into fresh extraction socket after augmentation withautologous platelet concentrate and bone graft, using two stage protocol.Second stage study will be performed 5-6 months following implant placement.Abutments will be connected within 3-6 weeks and definitive metal ceramicrestoration will be placed.
EXPECTED RESULTS:The success of the implant will be determined by the crestal bone changes andstability after 6 months following the use of PRFM and Bone graft (DFDBA).
CONCLUSION: Theaugmentation procedures have proved to be effective to achieve bone fill aswell as resolution of bone defects in surrounding implants. Bone augmentationalong with simultaneous implant placement may result in reduction of horizontalbone resorption.
KEYWORDS:Immediate implant, PRFM, DFDBA, Extraction socket, Atraumatic extraction.
