Brief Summary

Several minimal invasive techniques have been proposed since the last decade aiming to enhance and provide adequate environment for periodontal regeneration. Harrel and Rees proposed minimally invasive surgery (MIS) in 1995 and minimal invasive surgical technique (MIST) that was introduced in 2007 and then further enforced with modified minimally invasive surgical technique (M-MIST) in 2009 . A new minimal invasive technique called Non-Incised Papilla Surgical Approach (NIPSA) was introduced in 2017. It is aims to maintain the marginal tissues integrity by placing horizontal or oblique incision apical to the defect approaching the defect through apical access.

Study Arms (2)

NIPSA technique with Allograft plus PRF

EXPERIMENTAL

Non-incised papilla preservation technique to treat intraosseous bony defects with the addition of Allograft plus PRF

Procedure: Non-Incised Papilla Surgical Approach

NIPSA technique

ACTIVE COMPARATOR

Non-incised papilla preservation technique to treat intraosseous bony defects without the addition of Allograft plus PRF

Procedure: Non-Incised Papilla Surgical Approach

Interventions

Horizontal or oblique incision is done on the buccal mucosa as far as possible from the marginal keratinized tissue and the inter dental papilla The horizontal/oblique incision is extended mesio-distally enough to allow proper visualization of the defect A full thickness flap is elevated apico- coronally to expose the coronal limit of the defect Scaling and root planning are done using mini-curettes and power driven ultrasonic tips with care trying to maintain fibers attached to the cementum Granulation tissue is removed with mini-curettes detached from the bony walls and removed from the base of the papilla carefully with microblades and microscissors . 1ry soft tissue closure will be performed by horizontal mattress suture 2mm from the edges of the incision as a first line of closure and then simple interrupted suture as a second line of closure using (5-0, 6-0) polypropylene suture.
