简要总结
compare autogenous bone graft, xenograft and nanohydroxyapatite in immediate implant w placement in maxillary esthetic zone with provisionalization
详细描述
Placement of implants into extraction sockets targets the maintenance of peri implant hard and soft tissue structures and the support of a natural and esthetic contour. The main advantages of immediate implant insertion in comparison with delayed implant placement protocols are as follows: a reduced treatment time, less number of sessions, and, thus, the less invasive procedure. This study examines the clinical performance (survival rate, marginal bone levels and Pink Esthetic Score [PES]) of OsseoSpeed™ implants placed into extraction sockets with immediate provisionalization in the anterior maxilla after a follow-up of at least 12 months.
The removal of teeth results inevitably in both horizontal and vertical changes of hard and soft tissue dimensions.
Clinical research has shown that the loss of volume in the extraction sockets is high: the biggest bone volumetric changes take place during the first 12 months from the dental extraction, with a reduction of bone volume of 50%, of which 2/3 (30%) are within the first 3 months.
Nowadays to get success in postextraction implantology means managing the early and irreversible alveolar bone dimensional changes following tooth extraction, in order to minimize the negative effects on the aesthetics final.

研究组 & 干预措施
autogenous bone graft as a space filling material
Autogenous bone from sub mental bone had been grafted in jumping gap between implant and freshely extracted socket
干预措施: Autogenous bone graft as space filling in immidiate implant placment (Procedure)
deproteinized bovine as a space filling material
Granules of deproteinized bovine bone of 0.25-1.0 mm diameter were used to fill the remaining defect when the distance of the defect wall to the implant surface was > 3 mm.
干预措施: Deprotinized bovien as space filling in immidate implant placement (Procedure)
nano-hydroxyapatite alloplast as a space filling material
The patient was treated using alloplast material mixed with a nano-bone graft to fill gap between implant and freshely extracted socket
