This present study describes an impression technique to rehabilitate patients with flabby ridge in pre-maxilla through complete dentures. The proposed technique consists on the association of nondisplacive impression of the flabby area in the primary and functional impression. Therefore, a primary impression was performed with irreversible hydrocolloid with a dual impression. The impression material was removed at the region corresponding to the flabby area, characterizing a window, where a re-impression was conducted with the same material in a more fluid consistency. The functional impression was executed with a custom tray with perforations at the flabby area fabricated over a primary anatomic cast previously relieved. As a result, an anatomic impression with reduced compression over the flabby ridge was obtained. Moreover, an accentuated decrease of the mucosa compression was obtained through the material overflow from the custom tray perforations at the functional impression. After the acrylization of the prosthetic piece, a delimited box corresponding to the flabby mucosa in the prosthesis base was verified. Thus, it is concluded that the association of techniques proposed in this study reduced the compression over the flabby ridge area resulting in a complete denture copying anatomically the flabby area at rest. Thereby, in this case through a precise negative reproduction, a more favorable retention of the maxillary complete denture was obtained in patients with flabby ridge at the pre-maxillary area.

ABSTRACT Displaceable tissue on edentulous ridges may present a considerable clinical challenge to dental practitioners when providing complete dentures. Displaceable, or ‘flabby ridges’, present a particular difficulty and give rise to complaints of pain or looseness relating to a complete denture that rests on them. If the flabby tissue is compressed during conventional impression making, it will later tend to recoil and dislodge the resulting overlying denture.   A careful consideration and application of the principles of complete denture construction for such condition can provide a palliative form of treatment. This article describes reports of three such clinical cases, and demonstrates the use of a suitable impression technique. How to cite this article Sonune SJ, Singh S, Dange S.

Conventional Impression

Flabby maxillary ridge is the most commonly encountered clinical condition during routine dental practice. The presence of these displaceable denture-bearing tissues often poses difficulty during fabrication of complete dentures resulting in compromised support, retention and stability. Many impression techniques and materials have been proposed in various literatures to help overcome this difficulty. These techniques vary in philosophies but are often quite time-consuming to perform, and rely on materials not commonly in use in contemporary dental practice. The purpose of this paper is to describe an impression technique for flabby ridges, using conventional impression material.

ABSTRACTBackground: Impression making is one of the critical factors in determining success or failure of complete denture therapy. The precise reproduction of edentulous foundation is essential for retention, stability, and support of the removable prosthesis. Evidence suggests that there is variability in materials and techniques regarding impressions making for complete dentures. There is little published information on studies conducted among Nepalese Prosthodontists. The purpose of this study was to evaluate current materials andmethods for impressions for complete denture prosthodontics in Nepal. Materials & Methods: A questionnaire based survey was conducted among Nepalese Prosthodontists. Ethical approval for the beginning of the study was obtained via Institutional Review Committee, Nepal Medical College. A self-administered anonymous questionnaire was distributed to the participants. Data were analyzed by using frequency distribution.Results: Majority of responses indicated use of irreversible hydrocolloid in stock metal tray for making the preliminary impression. The selective pressure was the predominantly used impression philosophy (78.3%). The most common material for the fabrication of custom trays was autopolymerizing acrylic resin (96.7%). All respondents border molded the custom tray prior to making the final impression. The final impression materials used were zinc oxide eugenol impression paste (73.3%), polyvinylsiloxane (11.7%), polyether (11.7%) and polysulphide (3.3%). Conclusion: Although there is variability in impression materials andtechniques used by Prosthodontists in Nepal for the fabrication of complete dentures, the results showed interesting trends. Most practitioners followed the traditional techniques of complete denture impression procedures.Keywords: complete denture; custom tray; edentulism; impression.

Masticatory Efficiency

INTRODUCTION: Study aimed to investigate the influence of mandibular residual ridge shape on masticatory efficiency in complete denture wearer. MATERIAL & METHODS: Twenty-eight complete denture wearers of age group 45-65 who received their complete dentures and who had no complaints in daily use of them were selected for the study. The mandibular residual ridge was evaluated by using a replica of the ridge obtained using silicone impression material The basal area of the replica was measured by a Cercon eye scanner. The volume and the height of the replica were then mathematically calculated. Masticatory efficiency in each subject was measured by the sieving method. The data obtained were analysed through Karl Pearson’s coefficient of correlation. RESULTS: The results of this study showed significant correlation of the masticatory efficiency to the basal seat area, volume as well as to the height of the mandibular residual ridges. Among the three parameters, the basal area showed the strongest correlation. CONCLUSION: From this study, it was concluded that the basal area of the denture foundation greatly influenced the masticatory efficiency when compared to the volume and height of the mandibular residual ridge.

Efficient Alternative

Several implant impression techniques with different materials have been described in the literature. Generally, border molding, functional, and final impressions have been made with 3 different materials, which makes the procedure technique-sensitive and time-consuming. A combination of open-tray and functional impression techniques is described in this technical report. Border molding and functional impression procedures are made at the same time using a vinyl polysiloxane impression material, which makes this technique a simple and time-efficient alternative for clinicians.
