Atraumatic Extraction and immediate implant placement into infected site with the "ice cream cone" technique and L-PRF: A Case Report

ABSTRACT: We describe a case report of a 53 years old patient with osteopenia treatment, which presented a longitudinal root fracture in relation to 9 tooth Single Fixed Prothesis (SFP), an active fistula and a bucal plate loss. It was prescribed the tooth extraction and the immediate Biohorizons® Tapered Internal® implant installation. The regeneration of the bucal plate was performed using the technique of "ice cream cone" using Mineross®, Mem Lok® and L-PRF.

Immediate implant placement in periodontally infected sitescombined with concentrate growth factors:a clinical study / 安徽医科大学学报

To investigate whether the use of concentrate growth factors have a favorable impact on clinical outcome of immediate implant in periodontally infected sites.48 patients with 51 teeth with periodontitis and periapical periodontitis accepted immediate implantation in the maxillary esthetic zone.25 implants(test group) were placed simultaneously with guided bone regeneration (GBR) using CGF combined with Bio-oss, other 26 implants(control group) were treated with Bio-oss alone.The facial bone thickness at 0, 4 and 8mm apical to the implant platform were measured immediately after, 3 months after and 6 months after surgery;pain visual analogue scale (VAS) was used to assess the degreeof pain in the patient within 1 week after surgery.3 months after surgery,the change of horizontal resorption in labial was less in test group(P<0.05).In the first three days postsurgery, the test group reported significantly less pain with respect to the control group(P<0.05).The application of CGF produced beneficial impacts on clinical outcome of immediate implant in periodontally infected sites.
