Objectives: The purpose of this study was to compare the intraoperative and postoperative effects of Piezosurgery and conventional rotative instruments in direct sinus lifting procedure.
Patients And Methods: Twenty-three patients requiring direct sinus lifting were enrolled. The osteotomy and sinus membrane elevation were performed either with Piezosurgery tips or rotative diamond burs and manual membrane elevators. Time elapsed between bony window opening and completion of membrane elevation (duration), incidence of membrane perforation, visibility of the operation site, postoperative pain, swelling, sleeping, eating, phonetics, daily routine, and missed work as well as patient's expectation before and experience after the operation were evaluated.
Results: There was no significant difference between Piezosurgery and conventional groups regarding incidence of membrane perforation, duration, and operation site visibility as well as patient's expectation before and experience after the operation (P > 0.05). However, there were significantly more pain and swelling in the conventional group compared with the Piezosurgery group (P ≤ 0.05).
Conclusion: Sinus lifting procedure performed with Piezosurgery causes less pain and swelling postoperatively compared with conventional technique. Patients' daily life activities and experience about the operation are not affected from the surgical technique.

Background: A comprehensive investigation to associate the use of polynucleotides and hyaluronic acid with bovine bone in maxillary sinus lift procedures in rabbits has not been performed yet. The aim was to evaluate the influence of this novel association on the processes of bone regeneration in maxillary sinus augmentation.
Methods: In this prospective, randomized, within-animal model, maxillary sinus augmentation was performed bilaterally in 12 rabbits.

The decision to rehabilitate insufficient alveolar bone height with short implants is considered an effective treatment. Complicated surgical procedures such as ridge augmentation, vestibuloplasty, and sinus lifting are usually accompanied by high risks such as membrane injury, hemorrhage, nerve affection, and increased time needed for implant treatment with unpredictable healing time. Short dental implants allow for faster treatment and decrease the need for complicated surgeries that are usually associated with standard dental implants, as in all four and all six concepts.

Introduction: Platelet-rich fibrin (PRF) is being increasingly utilized in surgical procedures due to various improvements in clinical outcomes. More recently, a heating process to denature albumin in the platelet poor plasma (PPP) layer has been shown to extend the resorption time of PRF from a typical 2-week period to 4-6 months. Because of its > 4 month resorption properties, extended PRF (e-PRF) membranes have been used in dentistry as an alternative to collagen membranes in alveolar ridge preservations, ridge augmentations, soft tissue grafting, and as a barrier membrane in lateral sinus grafting procedures.

Article Synopsis
- * The procedure involves lifting the buccal fat pad and sinus mucosa under general anesthesia, then filling the resulting gap with a biomaterial that supports osseointegration.
- * With sufficient surgical experience, this method is considered a reliable solution for successful dental implant placement in the maxillary posterior area.

Objective: Although autogenous grafting is accepted as the gold standard in intraoral grafting, xenogenous grafts are frequently used in sinus lift surgeries due to their osteoinductive and osteoconductive properties. This study aimed to investigate the efficacy of fish spine-derived xenogenic grafts in sinus augmentation surgery.
Material And Methods: In this study, a fish spine-derived xenogenic graft was produced for comparison with autogenous graft and bovine derived xenogenic grafts.
