Immediate Implant Placement With Provisionalization Using Different Bone Grafts as a Space Filling Material in the Maxillary Esthetic Zone

Immediate Implant Placement With Provisionalization Using Autogenous Bone Graft Particulates vs Deproteinized Bovine Bone vs Nano-hydroxyapatite Alloplast as a Space Filling Material in the Maxillary Esthetic Zone

compare autogenous bone graft, xenograft and nanohydroxyapatite in immediate implant w placement in maxillary esthetic zone with provisionalization

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.

Inclusion Criteria:

• Adult patients with badly broken teeth in upper esthetic zone indicated for extraction
• Both sexes.
• No intraoral soft and hard tissue pathology
• No systemic condition that contraindicate implant placemen

Exclusion Criteria:

• Heavy smokers more than 20 cigarettes per day.
• Patients with systemic disease that may affect normal healing.
• Psychiatric problems
• Disorders to implant are related to history of radiation therapy to the head and neck neoplasia
