Window Technique for the Final Impression of a Maxillary Flabby Ridge: A Case Report of an Edentulous Patient

Abstract

The window technique is a highly useful clinical procedure for resolving several issues while taking a final impression of a patient with a mobile or displaceable anterior maxillary ridge, also referred to as a flabby ridge. This kind of ridge is particularly problematic due to the underlying tissues lacking strength and resilience, making it challenging to achieve a solid and comfortable denture fit. This typically exacerbates the problem, as conventional pressure during impression-making induces further displacement, which reduces the impression's precision. However, due to the utilization of a unique type of window in this impression technique, the window approach does not exert direct pressure on the flabby tissue. This innovative method of combining two types of impression materials, i.e., zinc oxide eugenol paste and impression plaster, with a window technique facilitates the fabrication of functional and well-fitting dentures by improving impression accuracy while reducing patient discomfort. The method outlined makes it easier for ordinary dentists to treat flabby ridge cases, allowing them to deliver patients with comprehensive care without the need for specialist referrals.
