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.

Soft and hard tissue evaluation for vestibular socket therapy of immediately placed implants in infected and non-infected sockets: a 1-year prospective cohort study.

Background: Immediate implant placement using vestibular socket therapy (VST) proved to offer a successful treatment option in compromised sockets. However, the presence of active signs infection complicates immediate implants in sockets with defective labial plates, due to the possible contamination of the implant or the bone graft with existing infected tissues or oral environment via the fistula. This study, therefore, aims to explore the success of immediate implant placement using VST in managing infected compromised sockets.

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).

Immediate implant placement utilizing vestibular socket therapy versus early implant placement with contour augmentation for rehabilitation of compromised extraction sockets in the esthetic zone: A randomized controlled clinical trial.

Objective: The present randomized controlled trial compares for the first time the vestibular socket therapy (VST) to the contour augmentation technique in the management of compromised fresh extraction sockets in the maxillary esthetic zone, regarding mid-facial soft tissue changes (primary outcome), mesial and distal papillae dimensions, horizontal soft tissue changes and labial bone plate thickness at apical, middle and coronal levels (secondary outcomes) over 1-year.

Materials And Methods: Forty participants with single nonrestorable maxillary teeth in the esthetic zone were randomized into two groups; VST (test; n = 20) utilizing vestibular access for guided bone regeneration (GBR) with immediate implant placement, or contour augmentation (control; n = 20) undergoing an initial healing period followed by implant placement with GBR through a conventional access flap.

Results: All implants were successfully osseo-integrated, except for one implant in the test group.

A technique for retrieving cement-retained implant prostheses.

Lack of retrievability is one of the most important disadvantages of cement-retained implant restorations. A straightforward and cost-effective technique for accessing the abutment screw channel and unscrewing the abutment and cement-retained prosthesis as 1 unit is described. The technique does not jeopardize the integrity of the restoration, screw, abutment, or implant.
