Details and patient eligibility

About

Procedure: Tooth is extracted, then A-PRF+ is placed inside the socket. After that the ridge dimensions is asses clinically at the baseline) in addition to clinical assessment of the gingival biotype at the baseline.

Then patients will be divided into 2 groups:

Group 1: 50% of patients will have recurrent Liquid-PRF injections inside the extraction socket every 2 weeks (A-PRF+, followed by recurrent Liquid-PRF) Group 2: 50% of patients without recurrent (just A-PRF+) After 3 months from extraction: both groups will be assessed clinically (gingival biotype) & (Ridge dimensions) in order to assess the role of recurrent application of Liquid-PRF on these parameters.

Full description

In this study, we will select 20 patients who need a simple tooth extraction, then determine the gingival biotype, take a blood sample to prepare A-PRF+ (centrifugation of the patient's blood for 8 min at 1300 rpm using red caps tubes), then do the extraction. After that, A-PRF+ is prepared and inserted into the extraction socket, and sutured using horizontal mattress suturing technique.

After the clinical assessment of the ridge dimensions at the baseline

Then patients will be divided into 2 groups:

Group 1: 10 patients will have recurrent Liquid-PRF injections inside the extraction socket every 2 weeks (A-PRF+, followed by recurrent Liquid-PRF) Liquid-PRF preparation: Centrifugation of the patient's blood for 8 min at 2500 rpm using white caps tubes.

Group 2: 10 patients without recurrent application of Liquid-PRF (just A-PRF+) After 3 months from extraction: both groups will be assessed clinically (gingival biotype) & (Ridge dimensions) in order to evaluate the effect of recurrent application of Liquid-PRF on these parameters.

Assessment method:

for Hard tissue evaluation (Bone): we assess the dimensions clinically For soft tissue: we will use a periodontal probe to assess the gingival thickness after giving local anesthesia.
