Effect of Surface Treatments Applied to 3D Printed Permanent Resins on Shear Bond Strength.

Background: 3D-printed permanent resins have recently been introduced to produce permanent restorations. The aim of this study is to evaluate the effect of surface treatment methods on the shear-bond strength (SBS) between 3D-printed permanent resins and adhesive cement.

Material And Methods: In this study, samples were produced using digital light projection (DLP) and stereolithography (SLA) 3D printers with two permanent resins (Crowntec, Saremco and Permanent Crown, Formlabs) in accordance with manufacturer guidelines.

Comparison of efficacy and usability of custom mandibular advancement devices fabricated with the conventional method and digital workflow: A pilot clinical study.

Purpose: To compare the effects of fabricating methods of custom monoblock mandibular advancement devices (MADs) on usability and efficacy in patients with mild and moderate obstructive sleep apnea (OSA).

Materials And Methods: Digitally fabricated custom MADs (dMADs) were produced for 11 OSA participants who had previously used conventionally fabricated custom MADs (cMADs). The participants answered a modified usability questionnaire for both MADs, and the average scores that were given to the questionnaire were evaluated by age, sex, and body mass index (BMI), and the scores of cMADs and dMADs were compared.

An Alternative Incorporation Technique for Minimizing Complications in Attachment-Retained Implant Mandibular Overdentures: Technical Report.

The present technical report aimed to display an alternative incorporation method for ball/stud attachments in mandibular implant overdentures (MIO) to prevent or minimize metal housing debonding and attachment malpositioning. Precoating of metal housings with auto-polymerizing acrylic resin (AAR) and fabrication of straight AAR bars onto metal housings for optimal parallelism were used as new techniques. The glossy flat surfaces of metal housings (matrices) were sandblasted and precoated with a thin layer of AAR in the laboratory.

Comparison of hemodynamic effects of lidocaine, prilocaine and mepivacaine solutions without vasoconstrictor in hypertensive patients.

Objective: Local anesthetic solutions with vasoconstrictors are not contraindicated in hypertensive patients, but due to their hemodynamic effects, local anesthetics without vasoconstrictors are mainly preferred by the clinicians. The aim of this study was to compare hemodynamic effects of three different local anesthetics without vasoconstrictors during tooth extraction in hypertensive patients.

Material And Methods: Sixty-five mandibular molars and premolars were extracted in 60 hypertensive patients (29 females and 31 males; mean age: 66.
