Advancing 3D dental scanning: The use of photogrammetry with light detection and ranging for edentulous arches.

Statement Of Problem: The advent of computer-aided design and computer-aided manufacturing (CAD-CAM) has necessitated the acquisition of digital scans. However, there are limitations and problems with acquiring accurate 3-dimensional (3D) casts from edentulous patients, especially in the presence of saliva.

Purpose: The purpose of this in vitro study was to develop a novel approach for obtaining 3D casts of edentulous arches by using 2-dimensional (2D) images as an alternative to traditional 3D scanners with and without light detection and ranging (LiDAR).

Maxillary interim obturator prosthesis fabrication for a patient with limited mouth opening with a digital approach: A clinical report.

Squamous cell carcinoma is a common malignant condition affecting the oral cavity and may involve the surrounding maxillofacial regions. Treatment commonly involves resection of the tumor, followed by prosthetic rehabilitation of the resection defect. This clinical report presents a 62-year-old Asian male patient who had previously undergone surgical resection, resulting in a post-surgical Aramany Class II maxillary defect.

CAD-CAM fabrication of semiprecision LOCATOR-style abutments to correct severely misaligned implants supporting a 4-implant maxillary overdenture.

Implant-supported removable overdentures are a popular treatment option with a favorable impact on a patient's quality of life. A maxillary removable overdenture without palatal coverage should be supported by at least 4 implants uniformly distributed around the arch and connected by either semiprecision attachments or a bar. Optimally these 4 implants should be parallel or have their long axes nearly aligned to facilitate the prosthodontic phase of treatment by allowing the use of standard components.

Mechanical properties of simulated dentin caries treated with metal cations and L-ascorbic acid 2-phosphate.

This pH cycling study aimed to investigate the effects of L-Ascorbic acid 2-phosphate (AA2P) salts of Mg, Zn, Mn, Sr, and Ba on the surface microhardness, compressive strength, diametral tensile strength (DTS), and solubility of root canal dentin. 186 cylindrical dentin specimens from 93 teeth were fortified with optimal concentrations of AA2P salts of Mg (0.18 mM), Zn (5.
