Evaluation of the 3D Augmented Reality-Guided Intraoperative Positioning of Dental Implants in Edentulous Mandibular Models.
This research aimed to propose a three-dimensional (3D) augmented reality navigation method with point cloud-based image-patient registration that could merge virtual images in the real environment for dental implants using a 3D image overlay and to evaluate its feasibility. ⋯ The proposed point cloud-based registration method can achieve excellent registration accuracy. Dental implant placement guided by the proposed 3D augmented reality navigation method showed better accuracy and applicability, as well as higher efficiency, than the traditional 2D image navigation method.

Randomized Controlled TrialA Prospective, Randomized, Open-Label Study Comparing an Opioid-Sparing Postsurgical Pain Management Protocol With and Without Liposomal Bupivacaine for Full-Arch Implant Surgery.
Mild to moderate pain is common following dental implant surgeries, although severe pain is reported in some patients. This randomized, open-label trial was designed to determine the efficacy and safety of an opioid-sparing postsurgical pain management protocol with or without local infiltration of liposomal bupivacaine for full-arch implant surgery. This procedure is used in edentulous and/or failing dentition patients and involves securing four or more implants to the maxilla and/or mandible to serve as anchors for dental prostheses. ⋯ Patients receiving an opioid-sparing postsurgical pain management protocol with liposomal bupivacaine 266 mg experienced a statistically significant reduction of postsurgical pain and clinically relevant reduction in opioid consumption. The overall incidence of treatment-emergent adverse events was comparable in patients receiving an opioid-sparing postsurgical pain management protocol with or without liposomal bupivacaine.

Evaluating Maxillary Sinus Septa Using Cone Beam Computed Tomography: Is There a Difference in Frequency and Type Between the Dentate and Edentulous Posterior Maxilla?
To analyze and compare the frequency, type, and location of maxillary sinus septa in patients with a dentate and an edentulous posterior maxilla using cone beam computed tomography (CBCT) imaging. ⋯ Sinus septa are frequent anatomical structures, and are found equally often in patients with a dentate and an edentulous posterior maxilla. This is of clinical relevance, as patients with missing teeth in the posterior area of the maxilla are often in need of a sinus floor elevation (SFE) procedure when dental implant placement is intended. As sinus septa are reported to be an important reason for surgical complications during SFE, a three-dimensional radiographic examination using CBCT prior to surgery might be helpful for diagnostic evaluation and treatment planning.

Randomized Controlled TrialCone Beam Computed Tomography Assessment of Maxillary Sinus Floor Augmentation Using Beta-Tricalcium Phosphate Alone or in Combination with Platelet-Rich Plasma: A Randomized Clinical Trial.
The aim of this study was to evaluate and compare the long-term clinical and radiographic outcomes between a bone graft substitute mixture (beta-tricalcium phosphate [β-TCP] and plateletrich plasma [PRP]) and β-TCP bone graft substitute alone used for sinus floor elevation. ⋯ In this study, PRP plus β-TCP graft substitute did not produce significantly more vertical bone height gain or significantly less vertical bone graft resorption compared with β-TCP graft substitute alone. Within the limitations of this study, however, it can be concluded that both grafting materials produced sufficient vertical bone height gain for safe implant placement.

Cell Attachment Following Instrumentation with Titanium and Plastic Instruments, Diode Laser, and Titanium Brush on Titanium, Titanium-Zirconium, and Zirconia Surfaces.
The aim of this study was to evaluate the surface characteristics and gingival fibroblast adhesion of disks composed of implant and abutment materials following brief and repeated instrumentation with instruments commonly used in procedures for implant maintenance, stage-two implant surgery, and periimplantitis treatment. ⋯ Repeated instrumentation did not result in cumulative changes in surface roughness of implant materials made of titanium, titanium-zirconium, or zirconia. Instrumentation with plastic implant curettes on titanium and zirconia surfaces appeared to be more favorable than titanium implant curettes in terms of gingival fibroblast attachment on these surfaces.
