The contour of the residual ridge is reduced within 1 year by approximately 25% in width after the extraction of a natural tooth. The augmentation of a tooth socket after an extraction decreases the loss of available bone width for an endosteal implant. Grafting at the same time as the extraction has benefits from both a patient and doctor perspective. However, primary closure is more difficult, and may require the facial keratinized gingiva to be undermined and approximated on the crest of the ridge, or the use of membranes, which are exposed during the soft tissue healing. The modified socket seal surgery uses a technique described by Landsberg and couples his procedure with autologous bone harvested from the maxillary tuberosity. As a result, the tooth extraction socket may be augmented with autologous bone and connective tissue with a simplified approach at the same time as the extraction of a tooth.

Dry socket, a common painful complication after tooth extraction, is typically caused by improper blood clot formation or its premature dislodgement, often exacerbated by bacterial infections. Traditional gelatin sponges, widely used as clinical fillers, provide favorable biocompatibility and hemostatic support but suffer from suboptimal hemostatic efficiency, lack of antimicrobial properties, and insufficient anticoagulant factors, which increase the risk of dry socket. Addressing these limitations, a novel tannic acid cross-linked gelatin sponge has been developed using directional lyophilization.

Background: Anatomically formed healing abutments were suggested in literature to address many of the issues associated with immediate posterior implant insertion such as large extraction sockets that are extremely hard to seal without reflecting the mucoperiosteal flap, extraction sockets anatomy that are not suitable for regular healing abutment placement, and potentially high occlusal stresses when planning a temporary implant supported prothesis to improve the conditioning of supra implant tissue architecture and the emergence profile of the implant supported restorations.
Purpose: To clinically evaluate the peri-implant soft tissue profile of single posterior implant retained restorations and to assess patient related outcomes of the implant restorations that were conditioned immediately by CAD-CAM socket sealing abutments (SSA) versus those conditioned by Titanium (Ti) standard healing abutments (SHA).
Methods: Twenty participants received twenty-two single maxillary immediate implants after flapless minimally invasive tooth extraction and 3D guided implant placement in the posterior area (premolar and molar) and allocated randomly into two groups (n = 11), the intervention group: patients received PEEK SSA and the control group: the patients received Ti SHA.
Asiatic acid methyl ester, a new asiaticoside derivative, induces osteogenic differentiation of hPDLCs.

Objective: Asiaticoside has the capacity to induce osteogenic differentiation of human periodontal ligament cells (hPDLCs) through Wnt (Wingless-related integration site) signaling. A modified chemical structure (by removing glycoside side chain), referred to as asiatic acid methyl ester (AA1), has been constructed and evaluated for its capacity to induce osteogenic differentiation.
Design: hPDLCs viability was determined by MTT assay.
Adequate Failure Loads for Modified Lemaire Lateral Extra-articular Tenodesis Are Achieved With an Interference Screw, Staple, and Suture Anchor: A Biomechanical Study of Structural Properties.

Department of Orthopedics and Rehabilitation, University of Vermont, Burlington, Vermont, USA.
Background: A lateral extra-articular tenodesis (LET) is increasingly being utilized to augment an anterior cruciate ligament reconstruction because it has been shown to reduce the risk of postreconstruction graft failure or recurrent rotatory instability. Various femoral fixation techniques are available, including the use of an interference screw, staple, or suture anchor.
Purpose: To determine and compare the biomechanical properties of an LET graft when using an interference screw, staple, or suture anchor for the femoral fixation for a modified Lemaire LET.

Article Synopsis
- Root caries pose a significant challenge in dentistry, requiring effective noninvasive preventive strategies due to poor outcomes of current restorative treatments.
- Researchers developed PAMAM-C11, a modified peptide that binds to hydroxyapatite to prevent demineralization in caries lesions and combat periodontal destruction, enhancing mineralization and resisting washout.
- PAMAM-C11 also protects against enzymatic breakdown in dentin, supports the growth of important stem cells for periodontal repair, and showed promising results in an in vivo rat model, suggesting its potential for clinical use in preventing root caries.
