ObjectiveThis clinical case describes a multidisciplinary retreatment of a patient with anterior fixed dental prostheses (FDPs) using minimally invasive restorations and a biologically oriented preparation technique (BOPT).Clinical ConsiderationsA 56‐year‐old female patient, treated 30 years ago with a metal‐ceramic FDP due to dental agenesis, presented a misfit prosthesis at the gingival margin, black spaces, and food retention at the pontics. Notably, tooth number 2.6 was absent, and she exhibited a left crossbite. Her chief complaint was the compromised esthetics of her restorations. Given her coagulation disorder, von Willebrand disease, she declined mucogingival surgery. A diagnostic wax‐up and mock‐up was performed to establish treatment goals. The initial phase involved periodontal, orthodontic, and implant treatment. The orthodontic treatment with aligners to correct the crossbite. Subsequently, bleaching and a second mock‐up were conducted to guide prosthetic treatment. In the prosthodontic treatment, the abutment teeth were prepared using a vertical BOPT to remodel the gingival tissues, achieving the esthetic goal of repositioning the gingival margin without surgery. The provisional phase was critical for soft tissue remodeling and ensured clinical success. After stabilization of the soft tissues, a monolithic zirconia FDP was delivered, with a follow‐up of 2 years.ConclusionsA multidisciplinary treatment plan, utilizing a digital workflow, resulted in stable clinical and esthetic outcomes at the two‐year follow‐up, effectively retreating an anterior bridge using BOPT in a patient with a coagulation disorder that contraindicated complex surgical interventions.

Background Vertical preparation techniques (VPTs), particularly the biologically oriented preparation technique (BOPT), have gained prominence in restorative dentistry due to their conservative approach to tooth structure preservation and improved aesthetic outcomes. This study aims to assess the knowledge and clinical practices of VPTs, including BOPT, among dental professionals in Sanaa, Yemen, and explore the barriers to their widespread use. Materials and methods An online cross-sectional survey was conducted among general practitioners and specialists in Sanaa, Yemen using a structured, self-administered questionnaire. The survey explored the participants’ knowledge, familiarity, and clinical use of VPTs and their perceptions of its advantages and challenges. Data were analyzed using descriptive statistics and Chi-square tests to evaluate associations between professional roles and VPT knowledge and practice. P values < 0.05 indicated statistical significance. Results Out of 285 participants, 76.8% were familiar with VPTs but only 11.6% reported using these approaches in clinical practice. The primary source of knowledge acquisition was informal, with 26.3% of the participants citing social media as their main resource. Specialists demonstrated significantly higher proficiency and confidence in applying VPTs compared with general practitioners ( p < 0.05). Key challenges identified in clinical adoption were controlling gingival bleeding (32.28%) and achieving precise margins during tooth preparation (34.74%). The majority (55.8%) of participants acknowledged the potential of VPTs as the future of restorative dentistry. Despite these benefits, 36.1% of the respondents emphasized the need for further training and educational programs to enhance proficiency and overcome the perceived complexity of these techniques. Conclusion This study highlights significant gaps in the knowledge and practice of VPTs, particularly BOPT, among the participants. While these techniques offer promising clinical and aesthetic benefits, their adoption is hindered by inadequate training and perceived complexity. Targeted educational interventions and further research are needed to support the broad implementation of VPTs in clinical practice. Clinical trial number Not applicable.

This work presents an original and very interesting approach to a calculus problem involving beams with intermediate supports through the transfer-matrix method, a very easy method to program to quickly obtain good results. To exemplify the applicability of this approach in dentistry, the calculus of a dental bridge on three poles is explored. Dental restorations are very important for improving a person’s general state of health as a result of improving mastication and esthetic appearance. The approach used in this study consists of presenting a theoretical study about an indeterminate beam with an intermediate support and then particularizing it for application in a dental restoration case, with a dental bridge on three poles and two missing teeth between the three poles. The bridge is assimilated to a simple static indeterminate beam. This paper is unique in that it involves the application of the transfer-matrix method for a case study in dental restoration. The assimilation of a dental bridge with a statically undetermined beam, resting on the extremities and on an intermediate support, is an original approach. The results obtained in the presented case study were validated by comparison with those obtained through the classical calculation of the Resistance of Materials, with Clapeyron’s equation of three moments. Due to the ease and elegance of solving various problems with the TMM, this approach will continue to be relevant to other original case studies with different modeling requirements, and these applications will be presented in future research.
