Teeth Extraction, Tooth Socket
Conditions
Brief summary
Alveolar bone resorption and labial bone plate reduction follow teeth extraction due to the deficiency of blood supply, derived from the loss of periodontal ligaments, and hence the socket shield technique with Bone graft was introduced to preserve the periodontal ligaments related perfusion and preserve socket dimensions for new bone formation. This study aims to compare implants placed in two differently preserved sockets, the first one preserved using Socket Shield technique with Autogenous Dentin Graft while the other socket preserved using socket shield technique with Alloplastic bone graft material
Interventions
PROCEDUREsocket shield technique with autogenous dentin graft
The crown of the hopeless tooth will be decoronated with a chamfer diamond bur and a large-head round diamond bur under copious irrigation, until the bone crest level. The root will then be sectioned along the long axis into buccal and palatal halves with a long shank fissure bur. The lingual root fragment will be carefully retrieved using microperiotome. The remaining buccal root fragment will be thinned and concaved slightly with a long shank fissure bur. The thickness of the buccal root fragment should be at least 1.5 mm to ensure resistance to fracture and resorption. The coronal part of this shield will be beveled to make a lingual slope for a better emergence profile with a large head round diamond bur. The socket shield will be checked for immobility so the implant could be inserted palatally into the socket shield. After the final preparation of the socket shield, Graft will be placed using autogenous dentin graft from the discarded palatal part of the tooth

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in implant stability | immeditely and at 3 months | it will be measured using Osstell ISQ, or Implant Stability Quotient, is a scale from 1 to 100 and is a measure of the stability of an implant. High stability means \>70 ISQ, between 60-69 is medium stability and \< 60 ISQ is considered as low stability. |
| change in bone density | at baseline and 3 months | it will be measured using CBCT |
| change in bone height | at baseline and 3 months | it will be measured using CBCT |
| change in Labio/Bucco-Palatal width | at baseline and 3 months | it will be measured using CBCT |
