Passive fit and time efficiency for prefabricated versus conventionally constructed cobalt chromium CAD\CAM 3-unit implant supported frameworks in free end saddle models: a pilot invitro study.

Background: The passive fit of 3-unit implant supported prefabricated metal screw-retained prosthesis before implant placement might be difficult. Hence, we aim to evaluate the passive fit and time efficiency of CAD/CAM 3-unit implant supported fixed prostheses that were constructed based on virtual versus those based on actual implant positions in Kennedy Class I models.

Methods: A sample of 5 Kennedy class I models with thin wiry ridges were restored by 20 frameworks bilaterally, 10 based on actual (group A) and 10 based on virtual (group V) implant positions.

Deviation parameters of intraoral scanning with and without artificial markers versus conventional impression of total, partial and congenital nasal defects: A pilot non-randomized clinical trial.

Purpose: This pilot clinical trial aimed to investigate accuracy of intra-oral scanning (IOS) with and without artificial reference markers in capturing total, subtotal and congenital nasal defects.

Basic Procedures: Thirteen patients with 3 types of nasal defects were selected and digitally scanned using an IOS with (ScM) and without artificial markers (Sc). Patients were grouped as follows; Group T (total nasal defect), Group P (partial/subtotal nasal defect), Group C (congenital defect).

A Cross-Sectional Study of Temporomandibular Disorders Among Postgraduate Students.

Purpose: To investigate temporomandibular disorder (TMD) prevalence as well as potential TMD risk factors among postgraduate students.

Materials And Methods: In this cross-sectional and correlation study, 1,255 postgraduate students from different universities were recruited to answer Fonseca's Anamnestic Index (FAI) in addition to collected demographic data and relevant dental history. FAI was used to classify TMD severity.
