Purpose: This in vitro study compared the dimensional accuracy of two impression techniques: Duralay splinted impression copings (D) and metal splinted impression copings (M) for implant-supported prostheses.
Materials And Methods: A master cast with four parallel implant abutment analogs and a passive framework were fabricated. Vinyl polysiloxane impression material was used for all impressions with a metal stock tray. Two groups (D and M) were tested (n = 5). The measurement method employed was just one titanium screw tightened to the framework. Each group's measurements were analyzed using software that received the images of a video camera coupled to a stereomicroscope at 3100 magnification. The results were analyzed statistically (t test).
Results: The mean values of abutment/framework interface gaps were: master cast = 32 Μm (SD 2), group D =165 Μm (SD 60), and group M = 69 Μm (SD 36). There was a statistically significant difference between the D and M groups (P ⋜ .001).
Conclusion: Under the limitations of this study, it could be suggested that a more accurate working cast can be fabricated using metal splinted impression copings.

Intra-oral flaps serve as a valuable solution for small to medium-sized oral cavity defects, yet complications such as flap sagging, tension at suture lines, mastication-related injuries, and patient discomfort remain challenges. The use of intraoral splint to support the flap diminishes these risks and complications. Conventional intraoral impression techniques are fraught with risks, including impression material infiltration and muco-compression, compromising blood supply.

This clinical report describes how a decubital ulcer arose from the direct contact of the vestibular movable mucous membrane against mini-implant balled-type heads after the mini-implant insertion in the edentulous atrophic mandible of a 78-year-old patient who was not wearing a conventional mandibular complete denture for more than 10 years. Due to severe alveolar ridge atrophy, mini-implant insertion (2.0 mm wide) was an option without extensive surgical procedures.

This study is aimed at detailing a technique for digitally fabricated fixed restoration for both immediate replacement after extraction and splinting of the adjacent mobile teeth. Demand for a fixed restoration of the missing teeth in the mandibular anterior region is very common but sometimes problematic for dentists. It often happens that there is significant loosening of the remaining teeth adjacent to the missing tooth, which should be splinted.

Article Synopsis
- The study aimed to assess how effective CAD/CAM technology is in designing and manufacturing 3D-printed dental models for creating splints for children with dental trauma.
- Researchers treated 28 patients, splitting them into two groups: one received CAD/CAM-based splints and the other wire-composite splints, with follow-ups over 24 months.
- Results indicated that while both splint types had similar outcomes, the CAD/CAM splint showed higher pulp survival and periodontal healing rates, suggesting its potential for reducing treatment-related injuries.
Dextrose neuroprolotherapy and occlusal splint treatment outcomes in occlusal trauma: Evaluation through ultrasound imaging.

Background: Occlusal trauma has become a common phenomenon among individuals today. Its primary source is bruxism, which involves unusual activities such as clenching and grinding during the day or sleep. The hypothesis is that with 5% dextrose neuroprolotherapy, both the trigger points and affected nerves will be healed, and the muscle will be relieved by eliminating the pain.
