Misfit detection in implant-supported prostheses of different compositions by periapical radiography and cone beam computed tomography: An in vitro study.

Statement Of Problem: Misfits at the implant-abutment joint (IAJ) can cause the biological and mechanical failure of implant therapy. Standard parallel periapical radiography (PERI) is the method of choice for assessing the fitting of implant-supported prostheses. Although current guidelines do not support the use of cone beam computed tomography (CBCT) solely for misfit detection, CBCT scans can also register misfits as imaging findings.

Accuracy of Three Cone Beam Computed Tomography Systems in the Detection of Implant-Abutment Misfit.

Purpose: To assess the accuracy of three cone beam computed tomography (CBCT) systems in misfit detection at the implant-abutment joint.

Materials And Methods: A total of 32 implants were placed in dry human mandibles. Porcelain-fused-to-metal crowns, both with and without a 200-μm-thick gap at the implant-abutment joint, were placed and then scanned using three CBCT systems: Picasso Trio (PT), OP300 (OP), and Scanora 3D (SC).

Accessory soleus muscle: a case report and clinical applicability.

Variations in leg muscle are uncommon. Literature on this subject is scarce, but when those variations are reported they may cause alterations in joint mechanics or cause some discomfort in the leg and foot. The accessory soleus muscle (ASM) is considered an unusual anatomical variation, with an incidence of 0.
