Factors associated with the non-adaptation to new mandibular complete dentures: a scoping review.

Purpose: To identify and map the scientific evidence regarding the factors that may influence the adaptation of complete edentulous to the mandibular complete denture.

Materials and methods: An electronic search strategy in the PubMed/MEDLINE, Web of Science, Scopus, Cochrane Library, and Virtual Health Library databases from 1945 to 2021, was conducted, according to the criteria established by PRISMA-ScR. Studies that addressed factors that influenced adaptation and acceptance to mandibular complete denture were included, such as socio-demographic and psychological aspects and patient-centered condition, and denturer-elated factors.

Results: The search yielded 9264 studies, of which 87 articles were considered eligible for full-text screening. Of this total, 23 were included for data extraction. Sociodemographic factors do not interfere with adaptation to a mandibular complete denture. Reports of complaints regarding pain and discomfort negatively impact the acceptance of complete dentures. Patients with a neuroticism personality have more difficulty accepting the complete dentures, being more predisposed to abandon them.

Conclusion: The psychological condition interferes with the predictability of treatment. Older and female patients, using first mandibular dentures, with resorbed ridges, and poor technical quality had more difficulty adapting to the complete dentures. However, these data must be interpreted with caution due to the variability of methodologies of the studies included in this review. Int J Prosthodont 2023. doi: 10.11607/ijp.7774.
