About

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.

Full description

Intraosseous vertical defects are one of the consequences that could result from periodontitis, which are classified according to their architecture by the number of residual walls, defect width as well as topographic extension in relation to the tooth. Conventional surgery done for regenerative purpose regarding vertical defects has been known to be affected by clot stability, it was reported in the literature that reduced clinical outcomes occurred when early wound failure and exposure of the treated area occurred. This led to the innovation of different minimally invasive flap techniques that aimed at reducing the surgical trauma, allowing blood clot stability, protecting the regenerating site, reducing patient discomfort postoperatively as well as minimizing surgical chair time Among these techniques are papilla preservation flaps and minimally invasive surgical approaches with papilla elevation or without papilla elevation . However, these techniques had in their design incisions related to the interdental papilla which would jeopardize and complicate the vascular integrity of the interdental tissues Non incised Papilla surgical approach is a new surgical technique introduced by Moreno Rodriguez in 2017 to maintain the marginal tissues and the papilla intact by placing a horizontal or oblique incision apical to the defect and approaching it through an apical access leaving the marginal tissues to act as a "dome " protecting the blood clot
