BUCCAL WALL AUGMENTATION WITH RESORBABLE MAGNESIUM MEMBRANE WITH IMMEDIATE IMPLANT PLACEMENT: CASE REPORT

Case presentation: Immediate implant placement with an immediate provisional on the implant is the most acceptable therapeutic solution for the patient. Early implant placement 4-8 weeks after tooth extraction with bone regeneration or immediate implant placement with bone regeneration are two options used when the prerequisite for immediate implant placement is missing, namely an intact buccal wall with a minimum thickness of 1 mm. The aim of this work is to demonstrate immediate implant placement with augmentation of the buccal wall with a new resorbable magnesium membrane. The patient came to the surgery because of residual tooth root of the maxillary second premolar. The therapy plan was the immediate implantation. CBCT revealed residual tooth root of the maxillary second premolar with very thin buccal wall. After lifting the mucoperiosteal flap and showing residual tooth root, the tooth root was extracted and an implant was immediately placed in that place. A magnesium-based resorptive membrane (NOVAMag®) was placed to preserve original width of the buccal wall. The xenograft (cerabone®) was placed between the outer surface of the buccal wall and the membrane and between the implant and the inner surface of the buccal wall. T he diaphragm was fixed with magnesium-based resorbable screws (NOVAMag® fixation screw). A xenogenic collagen matrix (mucoderm®) was placed above the membrane for the purpose of soft tissue augmentation. Conclusion: The technique of augmentation and immediate implant placement demonstrated in this case improves architecture of the alveolar ridge after extraction and aesthetic outcome of the future prosthetic restoration.
