Fully digital workflow for a CAD-CAM custom healing abutment with an optimal emergence profile: A dental technique.

The preoperative fabrication of well-contoured, computer-aided design and computer-aided manufacturing (CAD-CAM), custom healing abutments is essential for guiding soft tissue healing and saving chairside time. This dental technique involves a fully digital workflow to fabricate a CAD-CAM custom healing abutment that relies on preoperative digital implant planning. The healing abutment is designed with an optimal emergence profile that can predictably direct the anatomy of the peri-implant mucosa.

Alogliptin attenuates testicular damage induced by monosodium glutamate in both juvenile and adult male rats by activating autophagy: ROS dependent AMPK/mTOR.

Monosodium glutamate (MSG) is one of the most commonly used food additives, known for its adverse health effects. Alogliptin (ALO) is a highly selective dipeptidyl peptidase-4 inhibitor, but its role in male reproductive function remains debated. The study was designed to evaluate and compare the potential of ALO in mitigating MSG-induced testicular toxicity in juvenile and adult male rats.

Single posterior implant-supported restorations fabricated using a scannable healing abutment versus a conventional scan body: A randomized controlled trial.

Statement Of Problem: The use of a scannable healing abutment is a convenient option for fabricating implant-supported restorations (ISRs) with a digital workflow; however, clinical studies evaluating prosthetic efficacy are lacking.

Purpose: The purpose of this randomized controlled trial was to investigate the prosthetic efficacy of definitive posterior single ISRs fabricated after scanning using a scannable healing abutment-scan peg (SHA-SP) in comparison with a conventional scan body (CSB). The time for data acquisition, quality of proximal and occlusal contacts, and relative occlusal force of ISRs were measured.

Quantitative and qualitative assessment of the wear pattern of two attachment systems of dissimilar materials for mandibular implant-retained overdentures: an in-vitro study.

Background: Attachment material is one of the contributing factors to the degree of wear of the attachment components in mandibular implant-retained overdentures. The purpose of this in vitro study was to compare the wear behavior of 2 different attachment systems of dissimilar materials in mandibular implant-retained overdentures by qualitative and quantitative methods.

Methods: Two attachment systems of different materials were utilized (n = 16); Titach (Dental Evolutions Inc, Beverly Hills, CA, USA) with a titanium-to-titanium interface and Locator R-Tx (Zest Anchors Inc, Escondido, CA, USA) with a titanium-to-nylon interface.

Positional transfer accuracy of titanium base implant abutment provided by two different scan body designs: an invitro study.

Background: The variabilities in design and material of scan bodies have a major role in the positional transfer accuracy of implants. The purpose of this invitro study was to compare the 3D transfer accuracy (trueness and precision) of titanium base (TB) abutment position provided by 2 different scan bodies: one-piece scan body (SB) in comparison to two-piece healing abutment and scan peg (HA-SP).

Methods: A maxillary model with a dummy implant in the 2nd premolar (Proactive Tapered Implant; Neoss) was 3D printed and TB (Ti Neolink Mono; Neoss) was tightened on the implant and scanned by using a laboratory scanner (inEos X5; Dentsply Sirona) (reference scan).

Registration of maxillomandibular relationship through a fully digital workflow for complete-mouth rehabilitation with screw-retained fixed implant-supported prostheses: A clinical report.

Digital recording of the maxillomandibular relationship by using intraoral scanning in completely edentulous patients for computer-aided design and computer-aided manufacture implant-supported prostheses can be challenging. This clinical report describes the fabrication of complete arch, screw-retained implant-supported prostheses in a completely edentulous patient with a fully digital workflow.

Color-invariant skin lesion semantic segmentation based on modified U-Net deep convolutional neural network.

Melanoma is a type of skin lesion that is less common than other types of skin lesions, but it is fast growing and spreading. Therefore, it is classified as a serious disease that directly threatens human health and life. Recently, the number of deaths due to this disease has increased significantly.

Retention of a telescopic overdenture on customized abutments after the simulation of 1 year in function.

Background: Telescopic implant-retained overdentures are considered one of the most common treatment modalities for edentulous patients.

Objectives: The aim of the study was to evaluate the retention of a BioHPP (biocompatible highperformance polymer) telescopic overdenture supported by customized abutments made from 2 different materials after the simulation of 1 year in function.

Material And Methods: Twelve models of a completely edentulous mandible were three-dimensionally (3D)-printed.

Retention of mandibular implant-retained overdentures with two different attachment designs: An in vitro study.

Statement Of Problem: Retentive force and loss of retention should be considered when selecting an attachment. Studies that evaluate the retentive force and the effect of repeated cycles of insertion and removal on the TITACH attachment with a metal-to-metal interface are needed.

Purpose: The purpose of this in vitro study was to measure the retention of mandibular implant-retained overdentures with 2 different attachment designs before and after 1000 insertion and removal cycles.
