Summary: The surface roughness did not significantly affect cellular behavior, but there were slight differences between materials. Cells grown on zirconia dioxide exhibited higher cytotoxic effects, while those on lithium disilicate showed lower inflammation expression.

Summary: Preserving marginal bone level is crucial for the success of dental implant therapy. This study found that platform-switching (PS) dental implants showed less reduction in marginal bone level compared to platform-matching (PM) dental implants, and had a positive impact on vertical and horizontal bone defects.

Summary: The study evaluated the efficacy of using three-dimensional preformed titanium mesh for non-contained horizontal defects in guided bone regeneration, showing significant hard tissue gain rates in all three groups, with better results observed in patients using cross-linked collagen membranes in combination with the titanium mesh.

Summary: This study aimed to investigate early bone healing around implants with non-modified and modified surfaces. Four different surface characteristics were tested in the mandibles of 6 dogs. The results showed that implants with surface modifications had higher bone-to-implant contact and more newly formed bone within the defect area compared to implants with non-modified surfaces. Acid-etching in oxalic and hydrofluoric acid was found to promote early formation of bone-to-implant contact.

Summary: This study aimed to assess the effect of anodization process on the adhesion of fibroblasts and bacterial adhesion on clinically used dental implant surfaces. The results showed that anodization reduced bacterial adhesion, while roughened surfaces improved protein adsorption, fibroblast adhesion, and viability.

Summary: The study demonstrated that customized healing abutments and collagen matrices are both effective solutions for socket sealing in immediate implant placement, although a higher volumetric variation can be expected in the presence of thin bone phenotypes.

Summary: The present study evaluated the biomechanical behavior of PEEK abutments with different heights on single titanium implants. The results showed that PEEK abutments can be indicated with caution for implant-supported rehabilitation and may be suitable as temporary rehabilitation.

Summary: The efficacy of long (>=2mm) compared to short (<2mm) shoulder height abutments in peri-implant marginal bone level (MBL) changes was investigated in systemically healthy individuals with at least one two-piece dental implant. Meta-analysis revealed that long abutments significantly exhibited lower MBL changes compared with short ones at <1 year and >=1 year. Studies with implants placed in a more subcrestal position showed less differences in MBL changes between long and short abutments.

Summary: The study found exogenous metal contaminants and other impurities in commercial titanium dental implants, which may provoke immunological reactions despite conforming to standard compositions. Further investigation into the clinical relevance of these findings and discussion on the adjustment of industry standards are warranted.

Summary: This in vitro study found that the use of transepithelial abutments in monolithic zirconia partial implant-supported fixed prostheses affects the size of microgaps at the implant-abutment interface. The group with transepithelial abutments had significantly smaller microgaps compared to the group with Ti-base abutments, with both groups falling within clinically acceptable ranges.

Summary: The study evaluated changes of implant surfaces with different roughness after instrumentation with ultrasonic-driven scaler tips of different materials. Results showed that all tips except resin left extensive residuals on the surfaces, with the least change resulting from resin or carbon tips on machined surfaces.

Summary: The study found that implants with prefabricated abutments experience less crestal bone loss compared to those with customized abutments and have a lower failure rate.

Summary: Fixed prostheses are common treatment options for edentulous patients, but researchers are exploring alternative materials due to limitations of titanium. This study used finite element analysis to evaluate the stress distribution in fixed prostheses with polymeric frameworks and different bone densities. The choice of framework material depended on spongy bone density. Soft frameworks were recommended for low-density cases to reduce stresses on bone tissues.

Summary: To address the problem of insufficient bone mass in the implant area, we performed vertical bone augmentation in the posterior mandibular region with the aid of a healing abutment. Data from patients with insufficient vertical bone height were collected, and the success rate of the implant surgery was 93.3%, with a mean vertical bone gain of 2.91mm. The peri-implant soft tissue parameters showed good results with no observed complications. Rating: 7/10.

Summary: This review paper focuses on histological clinical studies in humans that have examined the effects of different materials or surface treatments on peri-implant soft tissues. The results show the influence of different abutment materials on peri-implant soft tissues and highlight the need for further research in this area.
