The use of dental implants to support mandibular or maxillary overdentures is a widely used treatment modality. Advantages are an increase in retention, an increase in chewing ability, and easy access for oral hygiene procedures. While telescopic and conical crowns have been used for decades to connect natural teeth to overdentures, not many cases have been reported in the literature of telescopic crowns placed on implants to support overdentures. This article describes 7 patients with overdentures supported by telescopic crowns who received 65 implants (ITI Straumann). The cases presented in this report have been in function for up to 4.5 years. During that time no adverse events were reported. The use of telescopic crowns as attachments for implant-supported overdentures may be a viable treatment option.

Purpose: Implant-supported overdentures have been an effective treatment method for edentulous mandibles. However, the loading time after implant placement is still controversial. The purpose of this study was to evaluate the outcome of implant-supported overdentures using telescopic crowns for the treatment of edentulous patients with immediate loading protocol.

Background: The purpose of this study was to evaluate the effect of using different types of metallic and non-metallic telescopic crown attachment materials on wear resistance and surface tomography changes in implant-retained mandibular overdentures.
Materials And Methods: Completely edentulous mandibular epoxy models were fabricated, in which two implants were placed in the canine region and retained to the implants with three different material combinations used for the construction of telescopic attachments. Thirty-three identical mandibular overdentures were fabricated using the conventional standardized technique.

Article Synopsis
- Telescopic crown-retained dentures (TCDs) are widely used prosthetics for patients with missing teeth, but using a post and core (PC) treatment as an abutment often leads to failures, particularly due to fractures caused by extra axial forces.* -
- A study analyzed 246 patients and 399 PC treatments over up to 17.33 years, comparing two scenarios: PC treatment performed at the time of TCD fitting (PC1) versus after an abutment tooth fracture (PC2).* -
- Results indicated that PC2 had significantly lower survival rates than PC1, highlighting the importance of using PC1 when treating endodontically treated abutment teeth and the need for careful

Statement Of Problem: The long-term effects of wearing removable partial dentures (RPDs) remain unclear.
Purpose: This systematic review addressed the question "Is the long-term use of RPDs deleterious to the remaining teeth?"
Material And Methods: This review was guided by the preferred reporting items for systematic reviews and meta-analyses (PRISMA) checklist. Six databases and nonpeer-reviewed literature were searched in April 2024 without language or follow-up restrictions.

Objectives: The primary objective of the present retrospective clinical study was to determine the survival time of obturators while analyzing possible influencing factors.
Materials And Methods: This retrospective clinical cohort study analyzed the influence of various clinical factors on the survival probability of obturators and their follow-up outcomes using Kaplan‒Meier analysis.
Results: A total of 76 patients with 115 obturators were included in the study (47 men and 29 women, mean age 58.
