Clinical Longevity of Obturators in Patients with Jaw Defects: a Retrospective Cohort Study.

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.

Survival of Double-Crown-Retained Implant-and-Tooth- Supported Removable Partial Dentures: A ≥ 5-Year Clinical Follow-up Study.

Purpose: To assess the survival of double-crown-retained implant-and-tooth-supported removable partial dentures (DCR-ITSRPDs), evaluate abutment survival, and identify first aftercare measures.

Materials And Methods: The influence of various factors on the survival of the DCR-ITSRPDs and the abutments were observed in this retrospective and clinical follow-up study using the Kaplan-Meier estimate. In addition, the first-required aftercare measure for each prosthesis was evaluated.

Which Patient-Related Factors Influence the Outcome of Telescopic-Retained Removable Implant-Supported Dental Prostheses in Edentulous Patients?

Purpose: To survey the clinical performance of telescopic-retained removable implant-supported dental prostheses (TR-RISDPs) in edentulous patients, as well as incidental maintenance measures and technical complications.

Materials And Methods: In this retrospective analysis, the former presence of oral cancer, prosthesis location (maxilla or mandible), and participation in a follow-up program were analyzed as possible factors with an influence on survival and maintenance treatments of the TR-RISDPs and dental implants using Kaplan-Meier estimates.

Results: A total of 86 TR-RISDPs (mean follow-up: 4.

Survival time of post and cores after recementation: A 16-year retrospective study with special focus on loss of retention.

Objectives: Numerous studies investigating the survival time of post and cores have found that loss of retention is the most common cause of failure Nevertheless, investigations focusing on decementation, survival after recementation, and the influencing parameters in a large number of patients with long follow-up periods are lacking. Therefore, the aim of this short communication article is the survival analysis of post and cores after recementation and repeated loss of retention.

Materials And Methods: During the observation period (2004-2020), 653 patients received 953 post and cores.

Clinical performance of different types of dental prosthesis in patients with head and neck tumors-a retrospective cohort study.

Objectives: To investigate how different types of dental prosthesis perform in patients with head and neck tumors.

Materials And Methods: In this retrospective clinical cohort study, the impact of different patient-related factors was analyzed as influencing factors on the survival probability of dental prosthesis using Kaplan-Meier estimate. For analysis, the dental prosthesis was divided into groups: group 1 (fixed dental prosthesis), group 2 (removable dental prosthesis), group 3 (implant-supported dental prosthesis), and group 4 (prostheses anchored using wrought wire clasps and obturators).

Clinical Outcomes of Implant-Supported Dental Prostheses: A Retrospective Analysis Considering Patient-Related Factors.

Purpose: To investigate the clinical performance of implant-supported dental prostheses (ISDPs), this retrospective clinical study observed influencing factors on survival of the prostheses and necessary maintenance treatments during the observation time and complications of the dental implants.

Materials And Methods: Patients who were provided either with fixed implant-supported dental prostheses (FISDPs) or telescopic-retained removable implant-supported dental prostheses (TR-RISDPs) were included in this retrospective clinical study. Potential influencing factors on the survival probability of the prostheses were observed using Kaplan-Meier analysis: patient sex, type of prosthesis, location, dentition in opposing arch, participation in follow-up visits, and whether the patient had a previous history of oral cancer.

Nonprecious Alloy vs Precious Alloy Telescopic Crown-Retained Removable Partial Dentures: Survival and Maintenance Needs.

Purpose: The purpose of this retrospective clinical study was to evaluate the clinical outcomes of nonprecious alloy (NPA) vs precious alloy (PA) telescopic crown-retained removable partial dentures (TRPDs), the factors influencing survival, and the type and number of maintenance procedures required during the observation period.

Materials And Methods: This retrospective clinical study is based on 462 patients with a total of 572 TRPDs on a total of 1,946 abutment teeth. The following parameters were analyzed with Kaplan-Meier analysis: sex; alloy type; denture location; number and distribution of abutment teeth (Kennedy Class); vitality of abutment teeth; dentition in the opposing arch; and participation in follow-up visits.

Wear and Fracture Strength of New Ceramic Resins for Chairside Milling.

Purpose: The purpose of this in vitro study was to evaluate wear and fracture strength of chairside-milled new ceramic resins after artificial aging in a chewing simulator.

Materials And Methods: Two ceramic resins (Lava Ultimate and Vita Enamic) and two conventional ceramics (IPS Empress CAD and Celtra Duo) were tested. For analysis of wear, baseline and follow-up scans of the specimens were made, the scans were superimposed, and the wear was calculated.
