“…Our findings are in agreement with earlier studies. 17,23,25,26 This research exhibited that the majority of participants (45.6%) preferred to use polyvinylsiloxane as a material of choice for the final impression, followed by ZOE impression paste (34.6%) as a second option. It is obvious that there is an increase in the popularity of using elastomeric (non-aqueous) materials.…”

“…4 In Nepal, (73.3%) of dentists favoured using ZOE impression paste, followed by polyvinylsiloxane (11.7%), polyether (11.7%), and polysulfide (3.3%) respectively. 26 One of the major drawbacks of ZOE impression material is the rigidity after setting, which cannot be able to use for recording the undercuts. It was found that the most used impression philosophy in the current study was mucostatic technique (50.4%), which was followed by selective pressure (37.1%) and muco-compressive techniques (13.2%).…”

Background: The success of complete dentures mainly depends on impression-making accuracy; thus, dentists need to select the proper impression materials and techniques to achieve optimal outcomes. Objective: To determine the favoured impression materials and techniques used for complete denture construction among dentists practicing in the Central/Western regions of Libya. Materials and Methods: This study was conducted between July 2023 and September 2023. The questionnaire was comprised of 30 questions, which were divided into two parts including; 11 questions for demographic and professional attitude and 19 questions focused on professional steps of complete denture fabrication for edentulous patients. Results: The response rate for this questionnaire was (66%). It was revealed that (96.1%) of respondents used only irreversible hydrocolloid (alginate) as an ideal option for primary impressions. In response to the same question for final impressions, (45.8%) of participants exhibited that polyvinylsiloxane was the favourite choice. Regarding custom trays, (41.7%) of practitioners preferred using light-cured acrylic resin as a custom tray to take definitive impressions. (87.4%) of prosthodontists border molded the custom tray in sections by (81.9%), using modelling plastic impression compound by (92.1%). The most used philosophy for final impression making was the mucostatic impression technique by (50.4%), while (37.0%) used selective pressure and (12.6%) selected muco-compressive. Implant-supported overdenture was discussed as an alternative treatment by (65.4%). The obtained data was statistically analyzed using SPSS 28. Conclusion: This study reflects a diversity of opinion among Libyan dentists during the construction of complete dentures. The most commonly used material for primary impression was irreversible hydrocolloid (alginate) and for final impression was polyvinylsiloxane, which coincides with professional practices worldwide. Modelling plastic impression compound was the most preferred material for border molding. The mucostatic technique was the predominantly used impression philosophy for final impression making.

“…7 A study done by Bhochhibhoya et.al, also found that majority of practitioners in Nepal, utilize ZOE for making fi nal impression in auto-polymerizing acrylic resin made custom trays and preferred selective pressure impression philosophy. 8 The impressions made by students were assessed on the basis of criteria like errors during mixing, fl ow of the material, positioning of the tray, thickness as well as extension of impression material. The most common error was found to be lack of exposure of all tissue stops, which signifi es non-uniform thickness of material within the tray.…”

Introduction: An accurate impression is the foundation of denture fabrication process thus a practitioner should be aware of the possibility of including errors during this procedure. Time spent in making a good impression will reduce the time required in adjusting the final prosthesis as well as make it more comfortable for the patient in accepting the prosthesis. Materials and Methods: Maxillary arch final impressions made by undergraduate dental students on 106 edentulous patients were evaluated. The impressions were assessed on the basis of criteria’s like errors on mixing, flow, tray positioning, presence of voids, creases/irregularities, exposure of tissue stops and extension at posterior border. The data’s collected were analyzed for the frequency of occurrence and distribution of each type of errors. Results: It was found that 97.2% of students performed at least one detectable error during making of maxillary arch final impression. The number of errors made by students ranged from single to as much as seven errors in one impression. The most common error was lack of exposure of all tissue stops followed by presence of voids and creases/irregularities on impression surface. Conclusion: There is high possibility of including errors while making maxillary arch final impression by undergraduate dental students. The study highlights the need to explore novel techniques of clinical demonstrations and teaching important concepts to learning students. The inclusion of more pre-clinical exercises in undergraduate curriculum relating to manipulation of dental materials may improve skills of students in making accurate edentulous impressions.

“…Resin-bonded fixed partial denture (FPD) is a legitimate treatment choice for the substitution of missing teeth in conditions when the protection of the tooth structure is required or the prosthesis assumes a transitional part in the oral cavity [3]. In spite of their inconveniences, for example, more regular rates of deboning than traditionally luted bridges, resin bonded FPDs have favorable circumstances, for example, an minimally invasive preparation, diminished cost and great patient acknowledgment [4]. Fixed prosthodontics is the area of prosthodontics concentrated on for all fixed dental prostheses.…”

The aim of this survey was to integrate impression techniques evolved all over the years for fixed partial dentures and to know the techniques and materials which are used in the present day by the practitioners. Material and methods: A questionnaire based survey was conducted among the dental practitioners of Makkah region of Saudi Arabia.. Ethical approval for the beginning of the study was obtained via Institutional Review Committee, Ibn Sina National College for Medical studies, Jeddah. A self-administered anonymous questionnaire was distributed to the participants. Data were analyzed by using SPSS 19 software. Results: Results shows that, majority of responses indicated use of irreversible hydrocolloid in stock metal tray for making the preliminary impression. 80% of them used retraction cord for gingival retraction and only few of them used elecrosurgery, lasers, rotary curettage and gingifoam. Maximum participants used hemostat along with retraction cord. Most of the participants used addition silicone with single mix heavy body with light body technique for making final impression and some of them used polyether. Conclusion: The ideal materials, technique, and armamentarium are required for the long-term success of the treatment for fixed dental prosthesis. Also, if the ideal procedure is not followed, it will lead to a compromised fit of the final prosthesis and failure of the treatment.
