Summary: This retrospective case series evaluated the short-term clinical advantages and limitations of full-arch implant-supported restorations made of monolithic zirconia suprastructures passively luted to titanium bar infrastructures. The study reported a 100% prosthetic survival rate with no implant failures or serviceable prosthetic complications. While two cases showed minor fracture lines in the zirconia suprastructures, no intervention was required. Long-term clinical studies are needed to confirm these outcomes.

Summary: This crossover clinical study aimed to evaluate and compare patient satisfaction and masticatory performance of mandibular two implant overdentures with zirconia bar and cobalt chromium bar attachments. The results showed that patient satisfaction with zirconia bar was significantly higher than with Co-Cr bar in terms of appearance, time, hygiene, recommend procedures, and overall experience.

Summary: This study describes a fully digital workflow for an implant-supported fixed hybrid restoration and highlights its benefits. The prosthesis consists of a titanium primary structure and a zirconia secondary structure, produced using a double CAD/CAM system. This procedure can be used for various cases, from simple to complex.

Summary: This study aimed to test the failure load and failure mode of a novel implant-crown interface for personalized zirconia CAD-CAM crowns. Results showed that the new interface exhibited similar failure loads as conventional interfaces, but with different failure modes. The study has important clinical significance, as it simplifies the digital workflow for ceramic implant reconstructions.

Summary: This study used the DLMS technique to design and insert an immediate post-extraction custom-made implant. After 10 years, the implant was found to maintain dimensional stability of the peri-implant soft tissues with no crestal resorption. This could potentially be a valid alternative to current immediate post-extraction implant procedures.

Summary: The study compared prosthetic aftercare between patients with two vs. four mandibular implant-retained overdentures and found that the use of four implants was more beneficial in relieving pressure sore spots. However, the number of implants did not have an influence on mechanical wear.

Summary: The study assessed the impact of different materials and base heights on the retention strength of hybrid-abutment crowns. The results showed that lithium disilicate had the highest retention strength, while zirconia had the lowest. Therefore, it is recommended to use etchable ceramics for CAD/CAM fabricated hybrid-abutment crowns.

Summary: An interdisciplinary approach is crucial in solving implantology problems. This study developed a mathematical model and methodology to analyze the mechanics of a complete overdenture based on a bar and four implants. The results provide insights into the strength of the implants and bone, and recommendations for the design and load distribution of overdentures.

Summary: The purpose of this study was to measure the flexural strength and failure load of acrylic resin immediate implant-supported interim prostheses fabricated by conventional processing and computer-aided manufacturing. The results showed that implant fixed interim structures milled from high-density PMMA blanks had a 35% higher flexural strength than heat-processed denture base PMMA. The low-profile coping design was stronger than the heat-processed material, and the failure point was relocated from the lateral walls to the cervical margin area.

Summary: This study evaluated the fracture strength of implant-supported provisional restorations made of PMMA when immersed in different solutions. The results showed that the fracture resistance was highest in distilled water and lowest in tea.

Summary: The study investigated the long-term performance of tooth-implant-supported and solely implant-supported double-crown-retained overdentures for complete restoration of the jaw over a period of up to 11 years. The results showed high survival and success rates for both types of restoration, but common minor complications required significant aftercare.

Summary: Obtaining accurate models and well-fitting prostheses for implant-supported prostheses is challenging. This study compared the quality of digital and conventional impressions for fabricating implant-supported complete bars. The results showed no significant difference in the misfit between bars fabricated using digital and conventional impressions, regardless of the number of screws used for fixation.

Summary: This retrospective study evaluated the long-term clinical and radiographic outcomes of zirconia-based screw-retained implant-supported zirconia fixed dental prostheses (ISZFDPs). The results suggest that zirconia-based ISZFDPs are a reliable long-term treatment option, with stable bone levels and low peri-implantitis rates.

Summary: The present study evaluated the histological and histomorphometric characteristics of post-extraction sites grafted with decellularized bovine compact bone, mixed and unmixed with leukocyte- and platelet-rich fibrin, after four months of healing. The results showed that socket preservation with a mixture of decellularized bovine compact bone and leukocyte- and platelet-rich fibrin demonstrated favorable results compared to using decellularized bovine compact bone alone.

Summary: This study retrospectively assessed the clinical and radiographic outcomes of immediately loaded full-arch fixed prostheses supported by axial and tilted implants for up to 15 years. The results showed a high survival rate for the implants, indicating that this technique is a viable treatment modality for immediate rehabilitation of both maxilla and mandible.

Summary: The study aimed to evaluate intra-arch mandibular dimensional changes during mouth opening using CBCT. Fifteen patients were enrolled in the study for pre- and post-CBCT assessment. CBCTs were taken with specific settings and measurements were made using radiographic markers. The results showed significant tightening and shortening of the mandible in the maximum opening position. These mandibular dimensional changes should be considered in treatment planning to avoid complications.

Summary: Restoring teeth with dental implants has become the gold standard in recent years, especially in the esthetic zone. Narrow diameter implants (NDI) may be a treatment option to resolve the limitations of limited available bone and interdental space in the anterior zone. This retrospective study compared the clinical and radiographic outcomes of one-piece and two-piece NDIs over a two-year follow-up period, showing comparable results in implant success, prosthetic failures, complications, peri-implant bone level changes, and Pink Esthetic Score.

Summary: This study evaluated the prophylactic effect of localized biomimetic minocycline and systemic amoxicillin on immediate implant placement at infected extraction sites. The results showed that localized minocycline could improve implant success by reducing bone loss and increasing removal torque, while systemic amoxicillin could maintain the stability of the peri-implant soft tissue. However, the combination of these two antibiotics did not enhance the prophylactic effect.

Summary: The performance of fixed complete dental prostheses supported by axial and tilted implants after at least 3 years of follow-up was evaluated. The results showed that tilted implants had lower marginal bone loss compared to axial implants, regardless of the maxillary or mandibular position. This surgical approach represents a predictable option for the rehabilitation of edentulous arches.

Summary: This in vitro study presents a debonding protocol for removing a screw-retained, monolithic, zirconia restoration from its titanium-base abutment. The abutment integrity was evaluated microscopically and no changes were reported in the structure and properties of the material. Further clinical studies with longer follow-up periods are needed to confirm these preliminary results.

Summary: This in vitro study compared the time required for implant site preparation using two different surgical prosthetic templates. The study found that the templates without metallic sleeves had a shorter preparation time. The type of prosthodontics surgical guide used can significantly impact the time and procedure for implant site preparation.
