Treatment of grade II furcation involvement using resorbable guided tissue regeneration membrane: A six-month study

Abstract

Aims:The present study was undertaken to evaluate the effectiveness of the combination of hydroxyapatite and β-tricalcium phosphate bone alloplast with bioresorbable guided tissue regeneration membrane for the treatment of mandibular grade II furcation defects.Settings and Design:A total of eight patients, four females and four males, in the age group of 18 to 65 years, with bilateral buccal grade II furcation defects in the mandibular molars, participated in the study.Materials and Methods:The following clinical measurements were recorded at baseline as well as three and six months post surgery: The Turesky-Gilmore-Glickman modification of the Quigley Hein plaque index, the Loe and Silness gingival index, Relative Clinical Attachment Level Vertical Probing Depth in the mid-furcation area, and Horizontal Probing Depth in the mid-furcation area.Statistical analysis:Pairwise comparisons within the groups were done by applying the independent student t test. Comparisons were also drawn between the test and the control groups by applying the independent student t test.Results:The mean gain in the relative clinical attachment levels in the test and control groups, at the end of six months, were 2.50 and 1.63 mm, respectively. The mean change in the horizontal probing depth values at the end of six months in the test and control groups were 2.88 and 1.63 mm, respectively. The mean reduction in the vertical probing depth values in the test and control groups were 1.50 and 1.38 mm, respectively.Conclusions:The resorbable GTR membrane with bone material was more effective than open debridement alone, in the treatment of furcation defects.

Comparative evaluation of effectiveness of concentrated growth factors (CGF) enriched bone graft matrix (sticky bone) with hydroxyapatite reinforced beta tricalcium phosphate and bioabsorbable membrane in treatment of class ii furcation defects -A clinical study

“…This nding has evidences from the literature showing, although limited, a mean PPD reduction by using HA/ β-TCP + GTR compared to monotherapy in management of furcation defects. 22,23 Similarly, statistically signi cant clinical attachment gain of 3 ± 1.12 mm was seen in HA/β-TCP + GTR group compared to sticky bone group 2 ± 0.85 mm at 6 months (mean CAL gain-1 ± 1.27; p < 0.05).These results are comparable with ndings stated in a literature where HA/β-TCP along with PLA-PGA membrane 23 ,collagen membrane 24 in class II furcation type defects reported a signi cant CAL gain after 6 months. Placement of a PLA-PGA membrane over DFDBA as a therapeutic modality in furcation defects had also indicated regenerative potential.…”

Clinical evaluation of porous hydroxyapatite bone graft (Periobone G) with and without collagen membrane (Periocol) in the treatment of bilateral grade II furcation defects in mandibular first permanent molars

“…compared open flap debridement with the use of collagen membrane and bone graft, and concluded that the use of bone graft in combination with membrane showed better improvement in the clinical parameters. [17] Surgical considerations like wound stability,[1] space maintenance,[18] and postoperative conditions[1] are particularly important aspects of GTR surgeries. Second-generation bioabsorbable membranes eliminate the need for second surgery for barrier removal, reduce the risk of loss of regenerated attachment, increase patient acceptance, integrate well with host tissues, enhance tissue coverage, reduce barrier exposure, and resist or prevent microbial colonization.…”

Comparative evaluation of platelet-rich fibrin versus beta-tri-calcium phosphate in the treatment of Grade II mandibular furcation defects using cone-beam computed tomography

“…[17] A hole in the horizontal direction approximately at the level of furcation entrance was made on the clear stent. The stent was used as the standardized, reproducible landmark to record the horizontal depth of furcation (H-DOF) at the follow-up interval [Figure 3].…”
