Background: The presence of black triangles around the dental implant-supported prosthesis and the failure to construct adequate papillae around them bothers dental implantologists. Peri-implant surgical soft tissue management will improve esthetics, function, and implant survival.
Aim: To compare the effects of rolled and nonrolled U-shaped flaps combined with a temporary crown in enhancing the soft tissue around dental implants.
Materials And Methods: Forty patients were included in this study; all patients were operated on by the same maxillofacial surgeon at Al-Iraq specialized dental clinics from January 2019 to January 2020. Patients were divided randomly into two groups: group A: at the second stage of implant surgery, a U-shaped flap without rolling was used in conjunction with temporary crown placement; group B: at the second stage of implant surgery, a U-shaped flap with rolling was used in conjunction with temporary crown placement. Then, the temporary crown was fabricated for both groups and kept in place for one month. Two independent maxillofacial surgeons evaluated all patients two weeks after the cementation of the final zirconia crown for the implant soft tissue esthetic score.
Results: The highest possible score assigned to the mesial papilla (2 scores) was present in 92.5% of the group A patients and only 77.5% of the group B patients. Moreover, we have found that alveolar bone contour is achieved perfectly (2 scores) in 70% of group A patients but only in 32.5% of group B patients.
Conclusion: The U-shaped flap without rolling with a temporary crown is a simple technique. It has good results, especially when there is no severe resorption of the labial bone plate (in canine and premolar areas).

Unlabelled: The aim of this work is to study the mechanical properties of temporary composite crowns and temporary composite orthopedic structures manufactured by 3D printing.
Materials And Methods: For the two studied groups of samples: the original 3D-printed samples and the poured samples from a composite material of a certain shape, 8 samples were made and visually checked for the absence of porosity. The strength and elasticity were measured using the three-point bending method and the hardness was measured using the indentation method.

Objective: This study evaluated the effects of finish-line design, tooth preparation taper or total occlusal convergence (TOC), and digital production technology on the retention of provisional crowns for molars.
Material And Methods: Different taper angles (10° TOC and 20° TOC) and finish line designs (chamfer and shoulder) were used to prepare four mandibular first molar teeth. Two subgroups of the prepared teeth received temporary crowns that were either "Computer-Aided Design" and "Computer-Aided Manufacturing (CAD/CAM) milled or 3D printed.

Background: This study aimed to analyze the effect of 3D printing temporary crowns on the single and continuous loss restoration of posterior teeth during secondary implant surgery.
Methods: This study adopted a single-center, randomized, single-blind, parallel-controlled trial design. Thirty patients who were admitted to the Department of Stomatology, Affiliated Hospital of Jiangnan University between January 2020 and February 2023 and who had >2 consecutive missing posterior teeth were implanted with the same implant system.
Flexural Strength of Different Commercially Available Auto-Polymerizing Acrylic Resins: An In Vitro Study.

Background Auto-polymerizing acrylic resins, composed primarily of poly(methyl methacrylate) and methyl methacrylate, are crucial in prosthetic dentistry due to their ease of use, cost-effectiveness, and acceptable aesthetics, polymerizing at room temperature to form solid polymer networks. One of the most important mechanical properties of these resins is flexural strength, which is essential for their performance under continuous masticatory forces. In clinical applications, prosthetic materials endure repetitive stress from chewing, and resins with higher flexural strength are better equipped to resist deformation and fractures.
