“…Cherkashin BF et al [40] developed a protocol for setting artificial teeth in completely removable prosthodontics without bite ridge landmarks based on comprehensive dentistry literature and clinical experience, leading to more efficient prosthesis fabrication for patients with complete secondary dementia. Von Stein-Lausnitz M et al [41] conducted a double-blinded randomized controlled trial to assess the impact of face-bow registration on occlusal parameters in complete denture remounting, revealing no substantial differences between face-bow and mean setting methods in changing the vertical dimension [42]. Steinmassl PA et al [43] evaluated various CAD/CAM denture systems, highlighting these technologies' potential to reduce patient visits and improve denture adaptation, with each system offering unique advantages based on the dentist's expertise and patient needs.…”

This manuscript introduces a novel two-step technique for fabricating mobile dentures post-extraction to streamline prosthodontic rehabilitation. The study utilizes various materials, including dental polymers, metals, ceramics, and composite materials, each chosen for their unique properties that contribute to the final prosthesis’s functionality, durability, and esthetics. The detailed procedure involves an initial occlusal registration immediately following tooth extraction, capturing precise occlusal relationships and a comprehensive dental impression. This approach reduces clinical visits and leverages optimal alveolar ridge morphology. The expected results highlight the efficiency of the technique, reducing treatment time without compromising quality and potentially improving patient satisfaction and prosthodontic outcomes. This innovative method conclusively promises rapid, efficient, and patient-centered dental rehabilitation, emphasizing the need for future research to validate its effectiveness and explore long-term outcomes.

“…Despite these results, there has been an ongoing debate on the utility of the face-bow transfer in clinical practice in prosthetic dentistry and orthognathic surgery [13][14][15][16][17][18][19]. One pilot study has questioned the bene t of the face-bow transfer in the treatment with splints in a special situation, and two studies have questioned whether the nal occlusion in complete dentures bene ts from the measure [20][21][22]. Several reviews have discussed the bene ts of using face-bows in prosthetic dentistry and pointed to a lack of evidence on the use of face-bows at that time [23][24][25][26].…”

Objectives This study aimed to determine whether the positioning of the patient in combination with force-controlled nasion support improves reproducibility in applying an arbitrary face-bow. Materials and methods 22 undergraduate students participated in the study as operators and repeatedly mounted an arbitrary face-bow on a single patient. Each operator performed the face-bow transfer twice, employing two different techniques. The standard technique used the classical rigid nasion adapter on a seated patient. In contrast, the novel method utilized a force-controlled nasion adapter which limits the force to the earbuds to 3 N on a reclined patient. The sequence of techniques was randomized (crossover design). Based on the face-bow transfers, randomly chosen maxillary casts were mounted in an individual articulator. The orientation of all models in the articulator was measured with a 3D-Digitizer at three predetermined sites. The differences between the means and specific positions were calculated, the means and standard deviations were computed, and significance tests were performed (Mann-Whitney-U-Test). Results Statistical analysis indicated a significantly smaller variance in the vertical plane for the patient in a reclined position combined with the novel nasion support (SD novel technique 5.187 vs. standard technique 6.309; p = 0.02). Conclusion Using the novel force-controlled nasion support to apply the face-bow in a reclined patient position improves reproducibility. Clinical relevance The application method for transferring maxillary casts to individual articulators should be altered towards placing patients in a reclined position with a nasion adapter that limits the force to the earbuds for better reproducibility.

“…Therefore, to minimize occlusal errors, maxilla should be related to the arbitrary hinge axis using facebow. 5,6 Ideally occlusal contacts in all posterior teeth are uniformly distributed and they should contact simultaneously. Clinically uneven pressure distribution on occluding teeth is due to nonuniform contacts created due to cuspal interferences.7…”

“…With rising awareness about evidence based dental practice it is important to identify and eliminate such unnecessary diagnostic procedures and ineffective therapeutic interventions. [1][2][3][4][5][6] This study is conducted to explore whether the use of facebow brings any benefit in patients requiring three unit fixed prosthesis.…”

The utility of facebow might reduce the occurrence of occlusal interferences in fabrication of three unit fixed prosthesis. There is a lack of data regarding the clinical usefulness of facebow in fixed prosthesis fabrication.The purpose of this clinical trial was to study and compare the occlusal interferences in three unit fixed prosthesis fabricated with and without facebow transfer.15 participants satisfying predefined inclusion and exclusion criteria were selected in this clinical trial. For each participant, 2 pair of three unit fixed prosthesis were fabricated. Prosthesis were fabricated one with and other without facebow transfer. The treatment involved single operator and single technician to minimize the error if any. After fabrication, the prosthesis were evaluated on the basis of the occlusal contacts and interferences of the three unit fixed prosthesis using a 40um articulating paper. The prosthesis with better occlusal contacts was cemented and the results were evaluated using chi square test.Nine out of 15 three unit fixed partial denture prosthesis fabricated using facebow transfer had reduced incidence of occlusal interferences. 6 out of 15 prosthesis fabricated without facebow transfer had reduced incidence of occlusal interferences. The results were evaluated using chi square test which was highly significant. (P>1), the three unit fixed prosthesis fabricated with facebow transfer had reduced no. of occlusal interferences.Taking into consideration of the complex and multiphase study design of the study with a finite number of participants and one specific arbitrary face-bow, the following result could be drawn as there is significant difference in three unit fixed partial denture prosthesis fabricated by the use of the arbitrary face-bow compared to a mean setting as compared to three unit fixed partial denture prosthesis fabricated without facebow transfer. The three unit fixed partial denture prosthesis fabricated with facebow transfer yields a better prosthesis and minimizes the harmful occlusal interferences as compared to the three unit fixed prosthesis fabricated without facebow transfer.Evidence based dentistry is needed to asses and abolish the unnecessary steps in clinical dentistry. Facebow is one such step which has been questioned for long by many clinicians and there is lack if clinical trials with its use in fixed prosthodontics. This study is to evaluated the importance of use of facebow transfer in fabrication of three unit fixed prosthesis.
