Using acrylic customized X-ray positioning stents for long-term follow-up studies.

Objectives: Long-term assessment of teeth, dental implants, and their corresponding structures is vital to obtain more data concerning the achievement or disappointment of different treatment modalities in clinical situations.

Aim: This report aimed to verify the usage of customized X-ray positioning stents suitable for long-term follow-up studies.

Material And Methods: Two acrylic stents were compared.

Comparative Study Clarifying the Usage of PEEK as Suitable Material to Be Used as Partial Denture Attachment and Framework.

Background: Utilization of attachments in a removable partial denture is highly essential not only as a line of treatment but also as it has a remarkable impact on the denture's durability during the function. The attachment should act as a stress breaking system preserving the abutment teeth.

Aim: This consideration aimed to verify the convention of polyether ether ketone (PEEK) material as an attachment.

Comparative Study Clarifying the Most Suitable Material to Be Used as Partial Denture Clasps.

Background: Removable partial denture's clasp is of particular importance as it affects the denture longevity during the function. The key of successful clasp selection is to select a direct retainer that will control tipping and torquing forces on the abutment teeth, provide retention against reasonable dislodging forces and are compatible with both tooth and tissue contour and the aesthetic desire of the patient. In this consideration, different materials employed for the clasp construction were compared mechanically.
