The current trial aim was to evaluate clinically and radiographically the changes around dental implants inserted immediately in maxillary anterior esthetic zone using a novel combination of autogenous demineralized tooth graft. with autogenous demineralized tooth plate and compared this approach to autogenous demineralized tooth graft.
The present study included 63 patients, aged 20 to 45, with teeth that needed to be extracted. After Kafrelsheikh University research ethics committee approval, patients were randomized into 3 groups: group I patients underwent immediate implantation with Duo-Teck membrane, while group II patients underwent the same procedure, but the dehisced bone defect was grafted by autogenous demineralized tooth graft. finally group III was grafted by combination of autogenous demineralized tooth graft. with autogenous demineralized tooth plate.
Patients with missing teeth face the prospect of tooth replacement either through the use of removable prostheses, fixed natural teeth-supported prostheses, or implant-supported prostheses. In many circumstances, implants are the alternative to fixed or removable prosthetic appliances.
One of the various indications of implant therapy is the replacement of periodontally hopeless teeth. The successful use of dental implants for more than 3 decades has been extensively documented for both conventional and immediate implant therapy.
The installation of implants in extraction sockets was advocated as a means to reduce the number of surgical procedures; to preserve the dimensions of the alveolar ridge; to reduce the interval between the removal of the tooth and the insertion of the implant supported restoration and furthermore, it may enhance osseointegration by taking advantage of the natural bone healing process around the implant.
A variety of regenerative techniques using combinations of bone grafts and barrier membranes have been suggested to promote bone regeneration in localized defects at implants placed into extraction sockets (Mayfield 1999). Bone substitutes were used to fill the marginal void between the implant and the bone, and barrier membranes were placed to protect the site during healing.
In the presence of fenestration or dehiscence defects, the potential for spontaneous bone formation at such defects is poor, so it is advised to use augmentation procedures for bone enhancement. Bone augmentation procedures are effective in promoting bone fill and defect resolution at implants placed in post-extraction sites, and are more successful with immediate and immediate-delayed placement than with conventional delayed placement.
The current trial aim was to evaluate clinically and radiographically the changes around dental implants inserted immediately in maxillary anterior esthetic zone using a novel combination of autogenous demineralized tooth graft. with autogenous demineralized tooth plate and compared this approach to autogenous demineralized tooth graft.

| Stability Quotient of dental implant (SQDI) | Osstell TM was used to record the primary stability.ISQ, or Implant Stability Quotient, is a scale from 1 to 100 and is a measure of the stability of an implant. The ISQ scale has a non-linear correlation to micro mobility. With more than 1400 scientific references, investigators now know that high stability means >70 ISQ, between 60-69 is medium stability and < 60 ISQ is considered as low stability. | 12-month. |
| pink esthetic score (PES) | The pink esthetic score (PES) evaluates the esthetic outcome of soft tissue around implant-supported single crowns in the anterior zone by awarding seven points for the mesial and distal papilla, soft-tissue level, soft-tissue contour, soft-tissue color, soft-tissue texture, and alveolar process deficiency.Using a 0-1-2 scoring system, 0 being the lowest, 2 being the highest value, the maximum achievable PES was 14 | 12-month. |
| facial marginal bone level (FMBL) | Utilizing CBCT sagittal sections, the BMBL was evaluated by computerized analysis. Navigation was done on the multiplanar display until the implant's precise same-view location was established on the reformatted cross-sectional section and panoramic view. | 12-month. |

Moreover, baseline, 6- and 12-months alterations of radiographic horizontal buccolingual ridge width (HBLRW), facial marginal bone level (FMBL), peri-implant Density of bone (PIDB) and peri-implant vertical bone defect depth (PIVBDD) changes were assessed using cone beam computed tomography (CBCT).
