An evaluation of a resorbable (semirigid) GTR membrane in human periodontal intraosseous defects: A clinicoradiological re-entry study

Abstract

Aim:To evaluate the effectiveness of a resorbable, semi rigid guided tissue regeneration (GTR) membrane in the treatment of periodontal intraosseous defects.Settings and Design:Randomized controlled clinicoradiological re-entry study.Materials and Methods:Eight patients with bilateral, identical intraosseous defects were selected. The sides for test and control group were randomly allocated to treat either with bioresorbable semi rigid membrane (test group) or open flap debridement (control group). Radiographic analysis was done by comparing intraoral peri apical radiographs taken at baseline and at six months. Extended cone paralleling device with grid was used to standardize radiographs. Auto CAD software was used for the analysis.Statistical Analysis Used:Paired-t test.Results:On surgical reentry at six months, the mean reduction in depth of the defect at the test site was 2.63 mm. The mean gain in Relative attachment level was 1.75 mm. The control sites showed a statistically insignificant gain. The mean percentage defect fill assessed on radiographs using auto CAD software was 15.54%.Conclusion:The resorbable, semi-rigid GTR membrane can be effectively used for the treatment of human one-walled angular defects.

Development of biodegradable silkworm cocoon derived silk membrane for GTR in the treatment of grade II furcation

“…The radiographs were enlarged to twice the original dimension and the area of interest was marked digitally so that any differences between preoperative and postoperative changes could be calculated. Although the X-ray grid can evaluate bone changes, AUTOCAD is more precise and can give values upto decimal points (Melke et al, 2016;Gowda et al, 2011). This is in accordance to a study done by (Yajamanya et al, 2017).…”

Clinical and Radiographic Evaluation of Regenerative Potential of GTR Membrane (Biomesh®) along with Alloplastic Bone Graft (Biograft®) in the Treatment of Periodontal Intrabony Defects

“…The results obtained are comparable with those of previous studies. [17][18][19] Radiographic monitoring of alveolar bone changes following regenerative procedures is a noninvasive, painless alternative to direct bone measurements; regeneration in periodontal defects is usually measured by bone fill in angular defects. In the present study, the radiographic assessment was carried out by analyzing defect.…”

Comparison of treatment effects of guided tissue regeneration on infrabony lesions between animal and human studies: a systematic review and meta‐analysis

“…Of these publications, 606 articles were excluded after reviewing the titles and abstracts. Furthermore, 27 reviews were excluded because four did not study periodontal defects , three did not provide outcome measurements , 18 had inadequate or incomplete data for analysis and two described defect depths of < 3 mm .…”
