Zygoma Implant-Based Rehabilitation of Three Patients with Primary Failure of Eruption of Teeth and a 5-Year Follow-up: A Case Series.

Primary failure of eruption (PFE) is a rare, nonsyndromic condition in which non-ankylosed teeth fail to erupt either fully or partially due to malfunction of the eruption mechanism. Three young patients are presented in this article with features consistent with a diagnosis of PFE. The features of this condition are described together with different modalities of treatment planning for such patients.

Comparative Evaluation of Wettability at Various Stages of Working Time for Light Body and Medium Body Consistencies of Three Elastomeric Impression Materials.

Aim: The main purpose of this study was to compare the wettability of light and medium body consistencies of three different elastomeric impression materials during their working time.

Materials And Methods: Vinylpolysiloxane, polyether, and vinylsiloxanether light body and medium body impression materials were used to fabricate the test samples. The contact angles of the impression materials were determined at 30 s from the start of mixing until their entire range of working time using a goniometer.

Influence of Cortical Layer and Surgical Techniques on the Primary Implant Stability in Low-density Bone: An Study.

Aim: This study aimed at evaluating the influence of cortical layer and surgical techniques on the primary stability of implants in low-density bone.

Materials And Methods: Two solid rigid polyurethane blocks with a density equivalent to 0.32 g/cm simulating cancellous bone were used.

Compatibility of Nonoriginal Abutments With Implants: Evaluation of Microgap at the Implant-Abutment Interface, With Original and Nonoriginal Abutments.

Purpose: The purpose of this study was to evaluate the fit of nonoriginal abutments to implants at the implant abutment junction.

Materials And Methods: Twenty titanium implants from a single manufacturer were randomly divided into 2 groups of ten each. Ten titanium premachined original abutments (group I) and ten titanium premachined nonoriginal abutments (from different manufacturer-group II) were connected to the implants with the recommended manufacturer torque level and then embedded into autopolymerizing clear acrylic resin blocks.

Restoration of Atrophic Edentulous Maxilla of a Patient with Ectodermal Dysplasia Using Quadruple Zygomatic Implants: A Case Report.

Rehabilitation of patients with ectodermal dysplasia often presents clinical challenge due to hypodontia, anodontia, and severe atrophy of edentulous ridges. Zygomatic implant therapy can be used as a method of achieving osseointegration without bone grafting in such situations. This clinical report describes the dental rehabilitation of atrophic maxilla of a 26-year old female patient with a fixed prosthesis, immediately loaded on four zygomatic implants.

Restoration of failing maxillary implant-supported fixed prosthesis with cross arch splinted unilateral zygomatic implant: a clinical report.

Management of one or more failing distal implants in an implant supported fixed prosthesis in a completely edentulous maxilla creates a challenging situation. Restoring immediate function with additional implants in such a situation can be a challenge considering the loss of supporting bone, need for grafting, age, and the patient's desire for immediate fixed dental prosthesis. This clinical report describes a situation where a zygomatic implant has been placed unilaterally and splinted with osseointegrated conventional implants by an immediate fixed provisional restoration.
