简要总结
Immediate tooth replacement with immediate implants into fresh extraction sockets has become a common and promising clinical procedure in daily practice in regard of implant survival, osseointegration and esthetic outcomes . However, there are some challenges encountered in the treatment of patients with labial bone plate dehiscence. Deficiency of facial bone anatomy has a negative impact on esthetics and is a critical causative factor for esthetic implant complications and failures ..
Few studies investigated the reconstitution of labial bone plate dehiscence using ice cream cone technique and their results showed adequate bone regeneration 4 to 6 months where no labial plate was present prior to grafting technique. Ice cream cone technique as a flapless grafting technique in conjunction with immediate implant placement in patients with labial bone plate dehiscence requires further studies for its clinical relevance and approval.
详细描述
Classical methods of guided bone regenerative methods succeeded to partially reconstitute the lost labial plate of bone using different grafting materials with barrier membranes.
This might be attributed to the necessity of using a full mucoperiosteal flap which interrupts the vascular supply to the bone and jeopardizing the process of total facial bone regenerative process. Therefore, Tan-Chu et al., (2014) described in a case report an innovative technique using resorbable collagen membrane in the shape of ice cream cone and allograft in the reconstitution of labial plate in patients with socket type II after extraction with folding the membrane to seal the socket and containing the blood clot to allow for occupation of osteogenic cell population without raising a flap. This technique showed an adequate bone regeneration with net result of 1.32 mm prior to no labial plate present before grafting. Hence, using immediate implant placement with the conjunction of the ice cream cone technique in regeneration of labial plate of bone needs to be further assessed to evaluate its clinical outcomes.
