The precision of an impression determines the subsequent accuracy and fit of the final restoration. Therefore, the ultimate search is for the most accurate impression material and the most efficient and least time consuming technique. One of the major debates in implant dentistry has focused on the advantages of the pick-up versus the transfer impression technique. The pick-up technique is widely accepted as the more accurate. However, the conventional transfer technique is simpler and less time consuming. The Hex-Lock-Friction-Fit impression coping (AB Dental Devices) combines the advantages of the transfer impression technique and the pick-up impression technique. In this article we will review the relevant literature, discuss the advantages of this unique implant impression technique, and present some related clinical cases.

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.

Abstract. According to conclusions of ITI World Congress (2018), the accuracy of the dental impression determines the quality of the working model and, consequently, the fixation of the prosthetic restorations at the final stage. Inaccurate dental impression will inevitably lead to technical and biological complications (Wolfart S., 2016). According to Lee and co-authors (2019), the accuracy of the dental impression is influenced by the chosen method, namely closed or open tray, the presence or absence of transfers splinting and the choice of impression material type. The most accurate impression has been proved to be an impression taken with the use of an open tray impression technique, by means of polyether impression material with preliminary transfers splinting using internally interfaced implant system. The objective of the research was to evaluate the quality of implants placement transferring to the model by comparative analysis of different methods of clinical transfers splinting in order to take impressions using an open tray impression technique. Twelve clinical situations were studied. Four groups were formed according to the method of transfer splinting. Each group included 3 clinical cases. Impressions were taken with the use of an open tray impression technique in all clinical cases with preliminary custom-made trays with holes in the implants projections. A grading scale was created when assessing the quality of transfer splinting as a key factor in the accuracy of implant placement transferring. Each of the groups received from 1 to 4 points where 1 point was the worst result according to this criterion and 4 points meant the best one. Among the criteria for splinting quality evaluation, 1-3 criteria were considered to be subjective, criterion 4 was considered to be objective. Therefore, criterion 4 received coefficient ×2 in order to increase the objectivity of the results evaluation. There were 4 criteria: The simplicity of the technique and the time spent splinting. The cost of the technique. Passivity when fixing the bridge prosthetic restoration after manufacturing. Radiologically measured distance between the centers of implant analogues on the model relative to each other after an impression taking by means of different splinting techniques and deviation of the value from the position of the centers of implants heads tops after osseointegration according to CT scan. Analyzing the results of the research, splinting techniques were ranked according to the obtained points. Research group 1 scored 6 points using dental floss and flowable compomer. A considerable amount of time was spent splinting with relatively inexpensive technology. The passivity of the fixation was the worst in comparison with other methods and the largest error was determined radiographically. Group 4 scoring 17 points was determined as the best of the chosen techniques. Despite the high cost of the chosen technique, prosthetic restorations made after transfers splinting by means of this technique had the highest fixation accuracy and the lowest deviation of the implants analogues on the model radiographically in comparison with the position of the implants in the upper alveolar ridge and lower alveolar ridge due to the cost of the material based on poly-vinyl siloxane.

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.

Abstract A quality-made dental impression is a prerequisite for successful fixed-prosthodontic fabrication and is directly dependent on the dimensional stability, accuracy and flexibility of the elastomeric impression materials, as well as on the appropriately used impression techniques. The purpose of this paper is to provide a literature review of relevant scientific papers which discuss the use of various silicone impression materials, different impression techniques and to evaluate their impact on the dimensional stability and accuracy of the obtained impressions. Scientific papers and studies were selected according to the materials used, the sample size, impression technique, storage time, type of measurements and use of spacer for the period between 2002 and 2016. In the reviewed literature several factors that influence the dimensional stability and accuracy of silicone impression molds, including the choice of the type of viscosity, impression material thickness, impression technique, retention of the impression material on the tray, storage time before the casting, number of castings, hydrophilicity of the material, release of byproducts, contraction after polymerization, thermal contraction and incomplete elastic recovery were presented. The literature review confirmed the lack of standardization of methodologies applied in the research and their great diversity. All findings point to the superiority of the addition silicone compared to the condensation silicone.

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.
