Brief summary
compare autogenous bone graft, xenograft and nanohydroxyapatite in immediate implant w placement in maxillary esthetic zone with provisionalization
Detailed description
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.
Interventions
PROCEDUREAutogenous bone graft as space filling in immidiate implant placment
* The selected patients will be informed of the nature of the research work and informed consent will be obtained (immediate implant placement grafting with autogenous bone graft) * Patients will be subjected to CBCT (diagnostic for upper arch). * Local anesthesia will be given to the patient. * Scrubbing and draping of the patient will be carried out in a standard fashion for intra oral procedures. * The procedure will be carried out flapless. * In the study group: Atraumatic extraction * The extraction socket will be evaluated for absence of any fenestration or granulation tissues
PROCEDUREDeprotinized bovien as space filling in immidate implant placement
* The selected patients will be informed of the nature of the research work and informed consent will be obtained (immediate implant placement grafting with deprotinized bovien material) * Patients will be subjected to CBCT (diagnostic for upper arch). * Local anesthesia will be given to the patient. * Scrubbing and draping of the patient will be carried out in a standard fashion for intra oral procedures. * The procedure will be carried out flapless. * In the study group: Atraumatic extraction * The extraction socket will be evaluated for absence of any fenestration or granulation tissues
PROCEDURENano-hydroxiapatite alloplast in immidiate implant placement
* The selected patients will be informed of the nature of the research work and informed consent will be obtained (immediate implant placement grafting with nano-hydroxiapatite alloplast material ) * Patients will be subjected to CBCT (diagnostic for upper arch). * Local anesthesia will be given to the patient. * Scrubbing and draping of the patient will be carried out in a standard fashion for intra oral procedures. * The procedure will be carried out flapless. * In the study group: Atraumatic extraction * The extraction socket will be evaluated for absence of any fenestration or granulation tissues
