Article Abstract
Transcrestal sinus floor elevation (tSFE) is a useful method for vertical bone augmentation in the posterior maxilla at the time of implant placement. However, this is a blind surgical technique with a risk of perforating the Schneiderian membrane. In this article, we present a simple technique to perform tSFEs using ridge spreaders. With this technique, the tSFE is performed in a slow and controlled manner without the entry of instruments into the maxillary sinus. Furthermore, many clinicians may find they already have the necessary surgical tools within their armamentarium. This precludes the need for rotary drills that spin at high revolutions per minute in the sinus cavity or osteotomes which may result in an uncomfortable patient experience. In order to fully exemplify its clinical utility in performing successful tSFE without membrane perforation, we present this surgical technique in a case with limited residual bone height and a steeply oblique sinus floor.

Transcrestal sinus augmentation has emerged as a minimally invasive alternative to lateral window techniques for vertical bone augmentation in the edentulous maxilla. Since its early introduction and modification over the last several decades, this technique has demonstrated predictable outcomes for implant placement in regions with limited bone height. This narrative review examines the current understanding and evolution of transcrestal sinus floor elevation (TSFE), focusing on factors related to long-term stability.

Orbital trauma can result in significant complications, particularly when accompanied by foreign body entrapment. Wooden foreign bodies are rare but carry a high risk of infection and chronic inflammation. In these cases, immediate surgical intervention is critical for restoring orbital anatomy and preventing complications.

Background: Oroantral communication (OAC) is a perforation between the oral cavity and maxillary sinus, commonly occurring after maxillary posterior tooth extraction. The role of imaging in identifying high-risk cases remains unclear.
Purpose: The study aimed to estimate the association between periapical and cone beam computed tomography (CBCT) imaging with OAC exposure during maxillary posterior tooth extraction and evaluate the necessity of CBCT in clinical decision-making.

: Maxillary sinus floor augmentation (MSFA) is commonly used to increase posterior maxillary bone volume prior to implant placement. Although generally successful, late complications can impact long-term outcomes. The purpose of the study was to estimate the incidence and timing of atypical late complications following (MSFA) using bovine xenohybrid bone grafts.

Purpose: This long-term retrospective case series study aimed to evaluate the efficacy and to identify risk factors for peri-implantitis associated with the one-step lateral sinus floor elevation (LSFE) procedure in patients with a severely atrophic posterior maxilla.
Materials And Methods: Clinical data were obtained from Periodontic Department at Taipei Tzu Chi Hospital. One-step, non-submerged LSFE enabled simultaneous implant placement in sites with residual bone height < 5 mm.
