The Simplified Papilla Preservation Flap in the Regenerative Treatment of Deep Intrabony Defects: Clinical Outcomes and Postoperative Morbidity

Abstract

The present study further supports the added benefits of guided tissue regeneration with respect to access flap alone in the treatment of deep intrabony defects, as well as the general efficacy of GTR in different clinical settings. Furthermore, our study indicates a possible influence of baseline tooth mobility on clinical outcomes.

Treatment of intrabony defects with guided tissue regeneration in aggressive periodontitis: clinical outcomes at 6 and 12 months

“…This type of flap design (SPPF) had been previously evaluated in a multicentre study where intrabony defects were treated with and without resorbable polylactide GTR membranes in severe CP. The 12-month results revealed a ΔCAL of 3.5 [2.1] mm and 2.6 [1.8] mm at the GTR and AF sites, respectively [25]. A similar ΔCAL was observed in the control group (SPPF 16 subjects completed the 6-and 12-month follow-up as 2 subjects were lost due to unrelated treatment reasons Two-wall (n) 1 0 6 Three-wall (n) 5 7 a The means with 95 % CI [in brackets] and ±SD of probing measurements of the defects at pre-surgery and intra-surgery PPD probing pocket depth, CAL clinical attachment level, CEJ-BD distance from cemento-enamel junction (CEJ) to the bottom of the defect, n number of defects alone) of the present study.…”

Regeneration of class II furcation defects: determinants of increased success

“…Trejo and Weltman (28) reported that intraosseous defects of teeth with Miller's class 1 and 2 mobility responded favorably to regenerative therapy. In contrast, Cortellini et al (41) reported that the greater the tooth mobility is at baseline, the smaller the clinical attachment level gain would be 1 year after regenerative therapy.…”

Periodontal tissue generation using autologous dental ligament micro-grafts: Case report with 6 months follow-up

“…Wetting the collagen III sponge with the micro-graft suspension after tissue dissociation, we reconstitute an activated undifferentiated tissue, able to produce by itself BMP-2 and VEGF for vascular net claiming and cell bridging. Then this cell suspension was grafted in the osseous defect with a mini-invasive surgical technique to avoid the depletion of the residual regenerating activity of the surrounding tissues that can occur after an extensive surgical trauma [31][32][33][34][35] . For the first 3 months we avoided performing an x-ray, although the emission dose is very low, in order to exclude any x-rays damaging the proliferating cells.…”
