Treating Intrabony Defect With MINST VS MINST Extended PRF (MINST PRF)
Clinical Effectiveness of Minimally Invasive Non-surgical Technique With or Without Extended Platelets Rich Fibrin in Intrabony Defects: a Randomized Controlled Clinical Trial
This study evaluates a minimally invasive non-surgical technique (MINST) for treating periodontal intrabony defects, with or without the addition of Extended Platelet-Rich Fibrin (e-PRF). The goal is to determine which approach provides better bone regeneration and gum healing.
Study Procedures
Control Group:
Local anesthesia by infiltration at the treatment site
Instrumentation of the root surface up to the bottom of the periodontal pocket
Efforts are made to minimize trauma to soft tissues and interdental papilla using subpapillary access
Cleaning is performed using piezo-electric devices with delicate tips, avoiding aggressive root smoothing or gingival curettage
3-4× magnification loupes are used to improve precision
Intervention Group:
All the above procedures
Followed by injection of e-PRF, a preparation derived from the patient's own blood
Blood is collected in 4 mL tubes and centrifuged at 700 g for 8 minutes
The platelet-poor plasma is heated to create an albumin gel
The remaining buffy coat (rich in platelets and growth factors) is mixed with the cooled albumin gel to form Alb-PRF, which is applied to the defect

Actieve vergelijker: MINST Alone
Participants will receive modified minimally invasive non-surgical periodontal therapy (MINST) alone. The procedure will be performed under local anesthesia using piezoelectric ultrasonic instruments with thin tips and magnification loupes while preserving root cementum and minimizing soft tissue trauma. No platelet-rich fibrin or other regenerative biomaterial will be applied. |
Modified minimally invasive non-surgical periodontal therapy performed under local anesthesia using piezoelectric ultrasonic instruments with thin tips and magnification loupes. The procedure aims to thoroughly debride the periodontal pocket while minimizing soft tissue trauma and preserving root cementum by avoiding intentional root surface smoothing and gingival curettage. |

Experimenteel: MINST + Extended Platelet-Rich Fibrin (e-PRF)
Participants will receive modified minimally invasive non-surgical periodontal therapy (MINST) followed by the application of autologous extended platelet-rich fibrin (e-PRF) into the intrabony periodontal defect. MINST will be performed under local anesthesia using piezoelectric ultrasonic instruments with thin tips and magnification loupes while preserving root cementum and minimizing soft tissue trauma. The e-PRF will be prepared from the participant's peripheral blood by combining heated albumin gel with liquid platelet-rich fibrin before placement into the defect. The protocol follows the procedures described in the study protocol |

Autologous extended platelet-rich fibrin (e-PRF) prepared from the participant's peripheral blood. Whole blood is centrifuged to obtain liquid platelet-rich fibrin, while the platelet-poor plasma is heated to form denatured albumin gel. The cooled albumin gel is mixed with the liquid platelet-rich fibrin to produce e-PRF, which is applied into the periodontal intrabony defect immediately after completion of the MINST procedure |
