Using Buccal Pad of Fat Free Tissue Transfer With Immediate Implant Placement

2020年6月2日 更新者:Dina Youssef Attia、Alexandria University

Evaluation of Using Buccal Pad of Fat Free Tissue Transfer With Immediate Implant Placement in the Maxillary Posterior Area

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.

研究概览

详细说明

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.

研究衡量的是什么?

主要结果指标

结果测量
措施说明
大体时间
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.
大体时间: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).

6 months
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.
大体时间: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)
6 months
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.
大体时间: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.

6 months
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
大体时间:6 months
Implant stability will be measured by implant stability meter (OsstellTM), immediately postoperative and after 6 months.
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.
大体时间: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.
6 months
