This systematic review aimed to determine the effectiveness and success rates associated with the use of orthodontic closure and dental implants to replace missing first molars. The results of the research taken into consideration in this paper were presented using the Preferred Reporting Items of Systematic Reviews and Meta-Analyses (PRISMA) framework. 8 of the remaining papers were selected because they met the inclusion criteria after 32 articles were excluded due to duplication. The remaining articles were examined in both their abstracts and full texts to determine their eligibility for this systematic literature review. Five studies were considered to provide evidence for implants used to replace the lost first molar, while three studies were included to show support for orthodontic closure. Since dental implants do not involve the other teeth surrounding the missing tooth, unlike orthodontic closure, which involves the entire dentition, they appear to be a better option for therapy.
