Biomechanical performance of dental implants inserted in different mandible locations and at different angles: A finite element study
Accurate implant placement is essential for the success of dental implants. This placement influences osseointegration and occlusal forces. The freehand technique, despite its cost-effectiveness and time efficiency, may result in significant angular deviations compared with guided implantation, but the effect of angular deviations on the stress-strain state of peri-implant bone is unclear.

Comparison of the weight of conventionally heat-processed hollow and solid obturators and 3D printed hollow obturators
The weight of larger obturators places increased stress on the supportive teeth and bearing tissue and allows gravity to act as a dislodging factor affecting the stability and retention of the prosthesis. However, whether conventionally processed and 3-dimensionally (3D) printed hollow obturators have similar reduced weights compared with solid obturators is unclear.

Comparison of trueness and margin quality of additively and subtractively manufactured definitive resin-based laminate veneers
Currently available 3-dimensional (3D) additively manufactured (AM) resins used for definitive restorations have different chemical compositions and viscosities. The fabrication trueness and margin quality of laminate veneers additively manufactured with different resins have not been extensively studied. (Source: Journal of Prosthetic Dentistry)

A computer-assisted endodontic access technique to remove fiber posts
Clinical treatments employing a 3-dimensional computer-assisted endodontic access technique (CEAT-3D) to remove fiber posts from posterior teeth in a minimally invasive manner using computer-aided design and computer-aided manufacturing (CAD-CAM) technology are described. Three patients with symptomatic molars and periapical radiolucency and with different treatment complexities had been referred for endodontic retreatment. For the removal of the fiber posts and endodontic retreatment, 3-dimensionally printed guides were designed from intraoral and cone beam computed tomography (CBCT) scans with a digital planning software...

Effect of stabilization of patients on the accuracy and scanning time of maxillary dentate quadrants: A clinical study
As intraoral scanning has gained widespread acceptance as an alternative to conventional impression-making, numerous studies have evaluated the influence of operator-related factors and patient-related factors on scanning accuracy. While several authors have noted patient movements as a clinical limitation of scanning technologies, research providing empirical data or testing this hypothesis is lacking.

Evaluating risk factors associated with poor removable prosthesis hygiene in community-dwelling elders: A cross-sectional study
Removable dental prosthesis cleanliness is multifactorial, and key clinical and nonclinical factors associated with prosthesis hygiene should be identified to inform practice, particularly given the dearth of studies relating specifically to prosthetic factors and prosthesis cleanliness.

Fabrication of a reverse-engineered custom scan body as a digital solution for recording implant position: A dental technique
A technique for the reverse engineering of the implant-abutment connection to fabricate a custom scan body is described. The implant-abutment connection was designed using the exocad software program, the scan body with screw channel was designed with the Blender software program, and the file was either 3-dimensionally printed in definitive tooth-colored resin with ceramic filler material or milled in polyetheretherketone (PEEK). This technique offers an accurate, cost-effective digital solution for implant optical scanning that can replace prefabricated scan bodies that may not be available for all implants. (Source: Jou...

Digitally designed occlusion of an implant-supported crown considering physiological tooth displacement under occlusal loading
Physiological natural tooth displacement under occlusal loading can influence intraoral occlusal contacts. However, gypsum casts and digital scans cannot simulate the physiological tooth displacement under occlusal loading. The occlusal design of the implant-supported crowns has been based mainly on the experience of dental laboratory technicians, lacking accuracy and individualization. Therefore, a digital technique that considers physiological tooth displacement is presented to design the occlusion of implant-supported single crowns. (Source: Journal of Prosthetic Dentistry)
