Comparison of AudaxCeph®'s fully automated cephalometric tracing technology to a semi-automated approach by human examiners.

Objective: To compare the reliability of cephalometric landmark identification by an automated tracing software based on convolutional neural networks to human tracers.

Materials And Methods: Sixty cephalograms were traced by two board-certified orthodontists and AudaxCeph®'s artificial intelligence software. The following thirteen landmarks were identified in each tracing: Sella, Nasion, A point, B point, Porion, Menton, Pogonion, Orbitale, Gonion, Upper Central Incisor Incisal Edge (U1 Tip), Upper Central Incisor Root Apex (U1 apex), Lower Central Incisor Incisal Edge (L1 Tip), Lower Central Incisor Root Apex (L1 apex).

Comparison of tensile bond strength of new and rebonded Symetri Clear™ ceramic brackets with Transbond™ XT or BluGloo™, with or without surface treatment: An in vitro study.

Objectives: This study sought to determine the bond strength of the Symetri Clear™ bracket after rebonding (reused) for a second and third time.

Materials And Methods: Symetri Clear™ mandibular incisor brackets were bonded to bovine incisors and divided into six experimental groups. Two groups underwent tensile bond strength testing, and the remaining four groups were debonded using the manufacturer's recommended plier.

Shear bond strengths of molar tubes bonded with different adhesives.

Aims: This study determined which molar base retentive designs produced the greatest shear bond strength (SBS) to human molars when using different adhesives.

Methods: One hundred and fifty extracted human molars were divided into 15 groups of 10. The tested molar tube bases included two stainless steel experimental base designs, a titanium single mesh 80 gauge base, a stainless steel double mesh 150 gauge under 80 gauge base and a stainless steel single mesh 80 gauge base.

Shear bond strength of four orthodontic bonding systems.

Recently new orthodontic bonding systems have been developed for attachment of brackets to the etched facial surfaces of teeth. Two of these new systems use bonding agents that contain solvents. It is claimed that this improves the polymerization of the unfilled resin primer and may increase bond strength.
