Clinicians treating overdenture patients need to know if immediate loading and conventional loading results in similar outcomes. This study aimed to perform a systematic literature search of studies comparing immediate and conventional loading of mandibular overdentures irrespective of the number of implants and conduct a meta-analysis of implant failure and marginal bone loss MBL. A literature search of PubMed, ScienceDirect, Ovoid, Springer, and Google Scholar databases was performed for randomized controlled trials RCTs comparing immediate vs conventional loading of mandibular overdentures. The primary outcome was implant failure and the secondary outcome was marginal bine loss MBL. A descriptive analysis was performed for other outcomes. Thirteen trials were included.

It is found to help in the preservation of alveolar bone and delay the process of complete edentulism. An overdenture is a denture, the base of which covers one or more teeth, prepared roots or implants. An overdenture is usually used for elderly patients that have lost some teeth but not all, rendering them suitable for a set of full dentures. An advantage of overdentures compared to full dentures is that the roots left in the maxilla upper jaw help preserve bone of the upper jaw, preventing bone resorption. The gums around the teeth must be relatively healthy for an overdenture to not cause any further problems. A maxillary overdenture may be supported by implants.
Background: It has been stated that mandibular overdentures are more satisfactory than conventional dentures, but problems relating to the use of retrospective ratings, lack of control group and sequential provision of treatment may compromise the findings. Objective: To establish a comparison between treatment with conventional complete dentures and implant-retained overdentures in elderly patients by conducting a literature review. Materials and methods: A search of English language peer-review literature was completed using Medline up to focusing on evidence-based research.
This article presents a comparison between different attachment systems used to retain and support maxillary and mandibular overdentures in completely edentulous patients. A literature review based on a MEDLINE search limited to English-language articles published from to the present was performed, and a large number of attachments available in the dental market were reviewed with regard to several factors, including: 1 implant survival rate, 2 marginal bone loss, 3 soft tissue complications, 4 retention, 5 stress distribution, 6 space requirements, 7 maintenance complications, and 8 patient satisfaction. These factors are considered essential for the successful outcome and good long-term prognosis of the prostheses. Selection criteria previously published in the literature are discussed as well.
