Abstract

In past, the materials used for denture bases were vulcanite, celluloid&phenol formaldehyde. Acrylic resins were introduced to dentistry in 1930's. There are certain limitations of acrylics like residual monomer allergy, poor mechanical strength, low fatigue strength, brittle on impact, poor conductors of heat, low hardness, high coefficient of thermal expansion, thermal shrinkage, poor color stability of self-cured resins, porosity, crazing, warpage, poor adhesion to metal and porcelain and requirement of mechanical retention. But still they are the most widely used denture base materials till date. But recently there has been much advancement in the field of denture base resins to overcome their drawbacks and to obtain an ideal denture base material. This article reviews the various advancements in the field of denture base resins.

Abstract

Objective: The aim of the study was to determine the clinical outcome when polyglactin 910 membrane was used to treat 30 patients with isolated buccal millers class II gingival recessions.
Materials and Method: Thirty subjects were selected with a chief complaint of hypersensitivity or denuded ischolar_mains; all were willing to participate in the clinical study. Inclusion criteria were the presence of 4mmor more of buccal millers class II gingival recession, a lack of contraindications for periodontal surgery.
Results: The mean reduction in clinical recession from baseline to 6 months postoperatively was 2.47±0.86 mm, i.e, 54%, which was statistically significant. There was a definite reduction in Pocket Depth, from a mean at baseline of 1.53±0.63mm to a mean of 1.07±0.26mm at 6 months. 
Conclusion: The use of GTR is a suitable alternative to the use of patient's own palatal masticatory mucosa. Polyglactin 910 as a GTR resorbable membrane gives the clinician another tool that provides acceptable ischolar_main coverage.
