U-Shaped Bone Splitting and Osteotome Techniques for Narrow Alveolar Ridge in Implant Surgery
Conclusions:
This technique is primarily useful for cases with a facial concavity. The modification could prevent iatrogenic labial bone defect during the surgery, and compared with onlay bone grafting, it may shorten the overall treatment time and avoid traumatizing the bone donor site.

Effects of Platelet Concentrates Used in Alveolar Ridge Preservation: A Systematic Review
Conclusion:
The effects of different kinds of platelet concentrates used in ARP might be different. Leukocyte- and platelet-rich fibrin might have a more positive effect on alveolar width and height preservation than platelet-rich plasma. However, randomized clinical trials included in the review were few and the strong evidence on this topic was not yet enough. (Source: Implant Dentistry)

Osteotome-Mediated Sinus Floor Elevation With or Without a Grafting Material: A Systematic Review and Meta-analysis of Long-term Studies (≥5-Years)
Conclusion:
High long-term implant survival was demonstrated after osteotome-mediated sinus floor elevation with or without a grafting material. However, long-term randomized controlled trials comparing the 2 treatment modalities are sparse. Hence, conclusions drawn from this systematic review should be interpreted with caution.

Effects of Simvastatin on the Viability and Secretion of Vascular Endothelial Growth Factor of Cell Spheroids Cultured in Growth Media
Conclusions:
Based on these findings, the application of simvastatin clearly decreased the cellular viability of the cell spheroids made with stem cells and osteoblast-like cells but increased the secretion of VEGF by the cell spheroids. (Source: Implant Dentistry)

Evaluation of Anatomical and Volumetric Characteristics of the Nasopalatine Canal in Anterior Dentate and Edentulous Individuals: A CBCT Study
Conclusion:
Severe bone resorption due to sustained edentation complicated implant surgery because of the increase in incisive and nasal foramen diameters and decrease in buccal residual bone dimensions. The NPC volume was found fewer in edentulous patients, and by the resorption, the volume was decreased. (Source: Implant Dentistry)

Use of Combination of Allografts and Xenografts for Alveolar Ridge Preservation Procedures: A Clinical and Histological Case Series
Conclusion:
Favorable clinical results were observed after the use of the combined bone graft, although a large variability in tissue proportions was present at 4-month healing time, especially for new mature bone. (Source: Implant Dentistry)

Doxycycline and Autogenous Bone in Repair of Critical-Size Defects
Purpose:
The association of doxycycline (DOX) and autogenous bone on repair of critical-size defects was evaluated.
Materials and Methods:
Fifty albino rats were divided into 5 groups (n = 10). A 5-mm diameter defect was treated with: control (CO)—blood clot; DOX in Natrosol (NAT)—10% gel; NAT—gel; particulate autogenous bone (PAB); and PAB + DOX − PAB associated with 10% DOX gel. The animals were euthanized at 4 and 8 weeks postoperatively. Histomorphometric analysis was performed to assess the percentage of new bone in the defect area. Statistical analysis of the results was performed using analysis of varia...

Rehabilitation of Postextractive Socket in the Premaxilla: A 12-Year Study on 27 Titanium Plasma Spray Resorbable Calcium Phosphate Coated Single Implants
Conclusion:
Although a good preservation of the residual bone tissue in postextraction implant sites treated with keratinized epithelial connective tissue grafts was observed, the low number of treated cases does not allow us to propose this experimental protocol to all cases of bone defects but it certainly represents a new option. Further studies on a greater number of patients and using implants with different surface characteristics should be conducted for a better understanding of the indications of the proposed treatment.

Influence of Cross-Section Design and Vertical Misfit on Stress Distribution in Overdenture Retaining System: 3-Dimensional Finite Element Analysis
Conclusions:
Higher vertical misfit increased the stress values on the overdenture-retaining bar system; complex cross-sectional designs increased stress values on the bar framework, prosthetic screw, and periimplant bone tissue; stiffer alloys caused higher stress values on all the studied conditions.

Osteotome Sinus Floor Elevation Without Grafting: A 10-Year Clinical and Cone-Beam Sinus Assessment
Purpose:
To evaluate the thickness of the sinus membrane in contact with implants inserted 10 years before using an augmentation procedure without grafting material, and to identify adverse events correlated with implant protrusion in the sinus.
Materials and Methods:
Osteotome sinus floor elevations were performed without grafting material. The implants (Straumann AG, Basel, Switzerland) were placed simultaneously, all protruded into the sinus. After 10 years, implants were considered viable in the absence of mobility, pain, infection, or continued radiolucency. Sinus health was assessed using cone-beam computed tomo...

Cone Beam Computed Tomography Evaluation of the Artery in the Lateral Wall of the Maxillary Sinus: Retrospective Analysis of 602 Sinuses
Conclusion:
Based on the CBCT scans, we found that a very high proportion of patients have the maxillary artery in their lateral sinus wall, which is important information for sinus augmentation or sinus surgery. (Source: Implant Dentistry)

Reliability of the Osstell Implant Stability Quotient and Penguin Resonance Frequency Analysis to Evaluate Implant Stability
Purpose:
To evaluate the reliability of the Osstell implant stability quotient (ISQ) and Penguin resonance frequency analysis (RFA) devices in measuring implant stability.
Materials and Methods:
Forty implants were embedded in self-curing acrylic resin, soft-lining material, polyvinyl siloxane impression material, and polycarboxylate cement (n = 10). After the initial setting times were completed, the stability of each implant was measured with Osstell ISQ and Penguin RFA with 3 repeated measurements. The “intraclass correlation coefficient” evaluated the correspondence between the measurements (P (Source: Implant Dentistry)

Influence of the Buccal Bone Crest Width on Peri-Implant Hard and Soft Tissues Dimensions: A Histomorphometric Study in Humans
Conclusions:
Similar hard and soft tissues dimensions were observed in both groups. However, a higher horizontal bone resorption was seen at the control sites. Nonsubmerged implant installation should be performed when a 1 mm buccal bony crest width is present so as to limit the horizontal bone resorption. (Source: Implant Dentistry)
