Brief summary
Implants placed immediately after tooth extraction usually present challenges in obtaining soft tissue coverage with high risk of bacterial invasion, wound dehiscence and subsequently adverse effect on the success rate of the implant due to lack of primary soft tissue closure over the implant. Different surgical methods have been described to achieve primary soft tissue closure in maxillary fresh socket, each having its advantages and disadvantages, based on that, buccal pad of fat can solve this soft tissue coverage problem with minimal complications and high success rate of the placed implants.The objective of this study is to evaluate the use of buccal pad of fat tissue with immediate implant placement in the posterior maxillary area.
Detailed description
Ten patients will be selected randomly from the outpatient clinic, Alexandria University seeking for an immediate implant placement. The sample will be selected to match the inclusion and exclusion criteria. It will be operated upon in the Oral and Maxillofacial Department, Faculty of Dentistry, Alexandria University. One stage surgery will include tooth extraction, placement of an immediate implant, bone grafting material and autologous soft tissue graft from the buccal pad of fat. Patients will be assessed clinically and radiographically to evaluate bone and soft tissue measurements.
Interventions
PROCEDUREXenograft bone substitute (Osteo-biol)
Xenograft bone substitute will be placed over the implant to cover the bone defect after extraction.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Evaluate postoperative pain when using the buccal pad of fat free tissue graft for primary soft tissue coverage with immediate implant placement in the posterior maxillary area. | 6 months | Postoperative pain will be recorded by each patient after 2, 6, and 12 hours postoperatively, then daily for the first week using: a 10-point Visual Analogue Scale (VAS) (17) from 0 to 10 (0 no pain, to 10 severe pain). |
| Evaluate swelling when using the buccal pad of fat free tissue graft for primary soft tissue coverage with immediate implant placement in the posterior maxillary area. | 6 months | Postoperative swelling will be recorded by each patient after 2, 6, and 12 hours postoperatively, then daily for the first week using a 10-point scale with 4 parameters will be used: none (no swelling), light (intraoral, localized to the treated area), moderate (extraoral swelling localized to the treated area), and severe (extraoral swelling extending beyond the treated area) |
| Evaluate soft tissue healing when using the buccal pad of fat free tissue graft for primary soft tissue coverage with immediate implant placement in the posterior maxillary area. | 6 months | Evaluation of soft tissue healing At week 1, week4 and at 6 months: Presence/absence of postoperative complications will be evaluated, including: Bleeding, hematoma, wound dehiscence, local infection, partial flap necrosis, excessive granulation tissue or vestibular obliteration, edema, facial asymmetry and mouth opening limitation. |
| Evaluate implant stability when using the buccal pad of fat free tissue graft for primary soft tissue coverage with immediate implant placement in the posterior maxillary area | 6 months | Implant stability will be measured by implant stability meter (OsstellTM), immediately postoperative and after 6 months. |
| Radiographic evaluation for using the buccal pad of fat free tissue graft for primary soft tissue coverage with immediate implant placement in the posterior maxillary area. | 6 months | After 3 months then at 6 months Cone Beam CT will be requested in order to measure: * Bone density. * Amount of bone buccally and palatally to the implant. * Marginal bone loss. |
